Halo (series)/Characters

Characters from  include:

Master Chief John-117
""This one is machine and nerve, and has its mind concluded...""

The Player Character and a central figure in the story's mythology. A Silent Protagonist outside of cutscenes, the Chief is the leader of the SPARTAN-IIs, a group of One-Man Army Space Marines serving in the UNSC. The SPARTANs were created to help the fight against human rebels, but once the Covenant showed up they took to that fight without complaint. As of Halo: Combat Evolved, John is officially the only survivor of the corps.

"343 Industries: A Spartan tossing his chest plate should feel like an anvil dropping… A Spartan sprinting across concrete should be a stealthy whisper... Putting on your helmet should feel like powering up an F-15E."
 * Authority Equals Asskicking- The highest-ranking Spartan-II and arguably the best.
 * After the war, he was given the rank of "Master Chief Petty Officer of the Navy", the highest enlisted rank in the UNSC navy.
 * Badass: How badass?

""He's received the highest commendations for bravery. Countless decorations for honor and selflessness. But Master Chief's greatest achievement reaches far beyond what any medal could ever hope to commemorate. For the men and women of the 26th Century, he is a human embodiment of possibility, the last Spartan standing against an angry tide. This strength of spirit is forged through his legend. Jericho VII. The Battle of Reach. High Charity. Tales rife with sacrifice and courage. Tales that grow, flourish, and inspire. And while he shapes his own history, he in turn shapes the history of all who follow. For no matter what horrors are released upon the day, they cannot match the reply of soldiers emboldened with his spirit, an army of Master Chiefs unto themselves.""
 * Born Lucky- Many people have stated that John is extremely lucky. Cortana even states in Halo 3 that, of all the other Spartan soldiers, she personally chose John because of his luck.
 * Considering Noble Six, who is the only other SPARTAN rated "hyper lethal", and his luck...
 * Child Soldier- All Spartan-IIs started at age six, receiving their augmentations and armor at 14.
 * Cyborg - Standard-issue Spartan-II enhancements: carbide-ceramic ossification (metal and ceramics on his bones), catalytic thyroid implant (containing human growth hormones), muscular enhancement injections, occipital capillary reversal (souped-up eyes), and superconducting fibrification of neural dendrites (Spartans literally think faster). And, finally, the Powered Armor that "connects" directly to his central nervous system.
 * Deadpan Snarker- He has his moments, especially in the novels.
 * "Thought I'd try shooting my way out...mix things up a little..."
 * Determinator
 * Famed in Story- His legend spreads from the ODST's that knew about him beating four guys to death in a gym without breaking a sweat, to his tales throughout the UNSC about him and his men defeating the Covenant, and even to the Covenant hating him with passion (or respecting him) for the destruction of the first Halo ring.
 * Subverted in the Believe Campaign. While he is honored as the savior of the human race, the battle depicted there is non-canon. Wild Mass Guessing and fanon consider it a massive ONI cover-up campaign to hide the truth about, y'know, all life in the entire galaxy nearly ending and all that.
 * First-Name Basis- With the other Spartans, Dr. Halsey,.
 * Genius Bruiser- He didn't reach Master Chief Petty Officer by brawn alone.
 * The Hero
 * Hope Bringer
 * I Gave My Word- "You know me. When I make a promise..." Cortana: "You... keep it... I do know how to pick 'em." Chief: "Lucky me."
 * Jack of All Stats- Noted as being great at everything, but having no skill standing out in terms of capabilities, except for leadership and luck.
 * Lightning Bruiser- As all Spartans are.
 * Made of Iron- The books make it clear that he's kept fighting despite heavy injuries on many occasions.
 * One-Man Army
 * The Paragon- Lampshaded in the Believe Campaign:


 * Powered Armour- MJOLNIR Armor, Models 4 through 6.
 * Spear Counterpart: Many consider him one of Samus Aran.
 * Sobriquet- "The Demon", to the Covenant.
 * Super Soldier- Spartan-II
 * Super Strength- Comes with the metal-laced skeleton, enhanced muscles, and power armor.
 * The Promise- See I Gave My Word above.
 * The Quiet One- Even compared to most of the other Spartans.
 * The Stoic

Cortana
An Artificial Intelligence and a main character in her own right, Cortana serves as Mission Control, whether she's uploaded into external computers or the Chief's Powered Armor. According to Expanded Universe material, she was created as tech support (on-the-spot hacking) for a secret mission into Covenant space, but as time goes on, her role gets a lot more complicated.


 * Brain Uploading- The manner of her creation, courtesy of a flash-clone of Dr. Halsey's brain.
 * Bob Haircut - From Halo 2 onwards. (though the trailer for Halo 4 shows her without them).
 * Captain Obvious- "This cave isn't a natural formation."
 * Deadpan Snarker- Oh, yeah.
 * Exposition Fairy
 * Ms. Fanservice
 * Hey, It's That Voice!- Jen Taylor, also known as Princess Peach and Zoey.
 * MacGuffin Girl
 * Me's a Crowd- Gained the ability to create imperfect clones of herself during the novel First Strike.
 * Playful Hacker- To her allies.
 * The Cracker- To her enemies.
 * Tron Lines
 * Voice with an Internet Connection
 * Voice with an Internet Connection

The Arbiter (Thel 'Vadam)
""...This one is but flesh and faith, and is the more deluded.""

A member of the Sangheili ("Elite") race of the Covenant, currently in disgrace after a serious failure. Given one last chance to redeem himself (or die trying) by stepping into the armor of The Arbiter, he becomes a second Player Character for part of the plot and eventually spearheads a diplomatic and military effort to rebel against the Covenant and seek alliance with humanity.


 * Authority Equals Asskicking- Was a Supreme Commander before being "Shamed". And considering how the Sangheili promotion system works...
 * Asskicking Equals Authority
 * Badass
 * Fire-Forged Friends- With the Chief during Halo 3
 * Hey, It's That Voice!- Keith David, most recently Sergeant Foley, but also Anderson, Childs, the Navy recruitment ad guy, and that dude who gets into a long fistfight with Roddy Piper over magic shades.
 * And Goliath.
 * Large Ham- Becomes a bit of one in Halo 3. Not as over the top as the rest of his people, though.
 * Laser Blade- Scarcely seen without his plasma sword.
 * Pre-Mortem One-Liner- "And so... you must be silenced."
 * The Atoner- Until he is betrayed and promptly learns that he really didn't have much to atone for in the first place.
 * Plays this straight in that he seems to feel some remorse for formerly aiding the war against humanity.
 * The Lancer- During Halo 3.

Ship Master Rtas 'Vadum

 * A Father to His Men- He even treats the Grunts with respect.
 * Four-Star Badass: Of a sort. In the end, Rtas isn't the commander of Special Operations for nothing.
 * Fan Nickname- Half-Jaw, due to the fact that he lost his two left mandibles.
 * Large Ham- Very.
 * "Ship-Master, they outnumber us, three to one!" Rtas: "Then it is an even fight. All cruisers fire at will! Burn their mongrel hides!"
 * Doubles as a Badass Boast.
 * Reasonable Authority Figure- Relatively
 * The Men First- "But these... are my Elites. Their lives matter to me; yours does not."
 * Well-Intentioned Extremist- Was willing to (and almost did) sacrifice humanity to protect the galaxy from the Flood, even after he had entered an alliance with them.

Sergeant Major Avery Johnson
""I would've been yo' daddy, but the dog beat me over the fence!""

Appearing in the first game as one of a number of computer-controlled Marines who can fight alongside the Master Chief, Johnson was the game's Ensemble Darkhorse. In later games he was critical to the plot, gaining Gameplay Ally Immortality and serving as The Lancer and Number Two to both the Arbiter and John.


 * Badass Boast: "Hell, Chief, it'll take more than that pack of walking alien horror-show freaks to take out Sergeant A.J. Johnson".
 * "Am I right, marines?!", "Sir, Yes sir!", "Mm-hmm, Damn right I am!". And that was just his first appearance.
 * He literally makes about a dozen.
 * Badass Grandpa- He's 82 years old.
 * Badass Normal
 * Bald Black Leader Guy- He actually has hair, but otherwise fits.
 * Inverted..
 * Defiant to the End: Even when he was beaten up by the Brutes, he refused to light the Halos. He instead shoved insults right at the Prophet of Truth's face.
 * Despair Event Horizon:  death seems to be this for him. He no longer fights the Brutes, or mocks Truth.
 * Determinator- He has his moments of this.
 * Friendly Sniper
 * Large Ham
 * Nice Hat
 * Sergeant Rock- Am I right, marines?!
 * SIR, YES SIR!
 * Mm-hmm, damn right I am.
 * Smoking Is Cool- Sweet Williams cigars.
 * The Lancer- Often plays this role to the Chief.
 * Your Mom- Sorta "I woulda been yo' daddy, but the dog beat me over the fence!")
 * Sergeant Rock- Am I right, marines?!

Captain Jacob Keyes

 * Badass: Captain Keyes is this any time he's commanding a ship. PERIOD.
 * Mind Rape-as the Flood sift his memories.
 * Heroic Willpower-part of how he resists said mind rape.
 * Captain Exposition
 * Mercy Kill- Received one from the Master Chief
 * The Captain
 * Oral Fixation Fixation: Keyes and his grandfather's pipe.
 * Reasonable Authority Figure
 * Reasonable Authority Figure

Commander Miranda Keyes

 * Action Girl
 * Badass Normal- Takes down two Brutes by herself and wounds several others with just a shotgun and a pistol.
 * Commanding Coolness
 * Julie Benz: Voices her in Halo 2.
 * Luke, I Am Your Father: Yeah we all know she's Keyes daughter, but what most people don't realize her mother is
 * Reasonable Authority Figure
 * Statuesque Stunner - She's five-foot-ten, according to the Halo Wiki
 * The Other Darrin - Voice actress change from Halo 2 to 3
 * "Well Done, Daughter" Gal- Her mother,, believes that she joined the UNSC Navy and changed her last name to Keyes to impress her father. Their relationship is never actually explored, so it is unknown how he felt.
 * According to the latest novel, Glasslands,
 * Sure, Why Not? - Speculation abounded that she was the daughter of Halsey as far back as 2005, based on small clues on the Bungie forums.

Fleet Admiral Terrence Hood

 * Big Good
 * Despair Event Horizon: He seems to almost reach it after the Battle of Earth, when Earth was saved from the Flood by sheer luck.
 * Knight Fever: That's Lord Hood - presumably a little historical joke.
 * Mission Control
 * Bald of Awesome
 * Reasonable Authority Figure
 * Ron Perlman- Voice

343 Guilty Spark

 * Affably Evil: He's not entirely evil, but he's so damn polite.
 * A.I. Is a Crapshoot- More than a little nuts from the get-go..
 * According to the Anniversary edition terminal in "The Silent Cartographer," Spark was entering prolonged periods of hibernation, and when he awoke he became so bored that he started conducting experiments on Installation 04 - such as blowing up sections of the surface and throwing them into space to see what would happen to the soil and organic life on those sections.
 * Ancient Keeper- Over 100,000 years old... and more than a little unhinged from the eons of isolation.
 * : It's hinted in Origins, from Halo Legends, that he was.
 * Beware the Nice Ones-
 * Big Bad: For Halo: Combat Evolved, even though he appears halfway through, and his intentions revealed even later.
 * Glowing Eye of Doom/Red Eye Take Warning
 * Not So Harmless- Oh, Spark's pissed. How sca-... ''did he just
 * Obstructive Code of Conduct- He appears to be serving the Forerunners (who are gone) and helping the 'Reclaimers' (which he doesn't do a good job at).
 * Smug Snake
 * Stop Helping Me!- Good gravy, shut up already!
 * Well-Intentioned Extremist- Sure he wants to activate the Halos, and through them kill all sentient beings, but what else can you do to beat the Flood.

The Prophet of Truth

 * A God Am I: Only in Halo3, which is at odds with his initial behavior in the second game.
 * Ax Crazy: He supposedly lost major traces of his sanity in between Halo 2 and Halo 3.
 * Big Bad Ensemble: Is just as much of a threat as the Gravemind in Halo 2 and Halo 3, though killing Truth before he activates the Halo rings is your top priority.
 * The Chessmaster
 * In the Back-.
 * Ironic Nickname- He's a complete liar and a psychopath to boot, but chose his title as a personal reminder of his hypocrisy.
 * Kick the Dog: Does this to Johnson after . "I see now why they left you behind. ...You were weak... and gods must be strong."
 * Manipulative Bastard
 * Meaningful Name- At the outset of the war, he took the title of "Truth" to remind himself of all the lies he'd have to tell to keep going.
 * The Other Darrin- Voice changed from Top Dollar in Halo 2 to Zod in Halo 3.
 * Omnicidal Maniac: The Omnicidal Maniac.
 * Psychotic Smirk: Gives one when he found the portal in ODST.
 * The Stoic: In Halo 2 he never showed any form of emotion, even with the facts of Halo 04's destruction and the discovery of Halo 05 but...
 * Not So Stoic:..in Halo 3 it's revealed that his stoic personality was just a facade to hide his psychopathic, sadistic personality and extremely high temper.
 * The Uriah Gambit: He pulled this one on both Regret and Mercy. When he tried it on the Elites however....
 * Villainous Breakdown: Experiences this in his final moments.
 * You Have Outlived Your Usefulness:
 * Why Don't Ya Just Shoot Him: Averted. Unlike his Brute Honor Guards, he does just shoot

 * You Have Outlived Your Usefulness:
 * Why Don't Ya Just Shoot Him: Averted. Unlike his Brute Honor Guards, he does just shoot

The Prophet of Mercy

 * Hidden Depths- While Truth is more secular and Regret is more dogmatic, Mercy is genuinely religious.
 * Ironic Nickname- He's a merciless bastard.
 * Well, only partly. He did stick his neck out for Regret during Halo2..
 * Satellite Character: His only actual function was to show that Truth was a Manipulative Bastard. His office was literally earned by being at the right place at the right time, and his earlier position was fraudulent and In Name Only (he "communicated" with the Dreadnought's Oracle, who was inert until Truth came there in order to become High Prophet.)

The Prophet of Regret

 * Curb Stomp Battle: It's entirely possible to just run up to his chair, avoiding his easily dodegable lasers, and punch him to death. At least on Normal or Easy. Trying this on Heroic or Legendary will get you shot to death by his dual-plasma rifle wielding Elite Mooks.
 * Disc One Final Boss: His forces make up all of the Chief's enemies in the first five human missions in Halo2, and four of those involve chasing him down before he activates Halo on Earth, but taking him out was only a small portion of the plot to the second game.
 * Flunky Boss: He's backed up by his respawning Elite Honor Guard. He'd be a pushover if it wasn't for them since his only attack is a very powerful (but easy to dodge) laser. He distracts you while his guards kill you, or vice versa.
 * General Failure
 * Glass Cannon: He's fairly weak by himself, but the cannon on his gravity chair is almost always a one hit kill.
 * Hot-Blooded: Something Truth was blaming him for when he attacked Earth, and it later had big consequences for his life and for Truth's plans.
 * It's suspected he caught it from working with the Elites.
 * Hypocritical Humor: "Such a frail thing. You would hardly think them a threat." This is coming from someone who never leaves his hover chair.
 * Ironic Nickname: If he regrets anything, up to and including what he had for breakfast, he didn't show it
 * Even afterward, he doesn't regret anything!
 * Large Ham: "I shall light this holy ring, release its cleansing flame, and burn a path into the DIVINE BEYOND!" We're not kidding; this is how he normally speaks.
 * Heck, that's the translated version. In whatever language he was talking in, it was a calm, steady hymn. And a worded version of the first game's theme.
 * Omnicidal Maniac: Somewhat subverted. It seems he genuinely doesn't know what the Halo rings do.
 * Properly Paranoid: Concerning Truth.
 * Smug Snake
 * Spanner in the Works: A milder form of this to Truth.
 * The Starscream: A mild and self-preservational example towards Truth, who he thought would ditch him as soon as he was no longer useful.
 * Youth Is Wasted on the Dumb

Tartarus, Chieftain of the Brutes

 * Asskicking Equals Authority: Comes with being a Brute Chieftain.
 * Bullfight Boss: Trying to use anything other than hit and run tactics will get you smashed by his gravity hammer
 * The Dragon: To Truth.
 * Drop the Hammer
 * Final Boss: For Halo2.
 * Flunky Boss: Has a few squads of brutes backing him up, though it hardly makes a difference since you have a bunch of Elites backing you up, so you're free to ignore them and just focus Tartarus.
 * Go Mad from the Revelation: Subverted. He gets all berserk when the Arbiter and 343 Guilty Spark tell him the truth of the Halos, but he refuses to believe it. It's a good hint that his rage was born from denial.
 * Large and In Charge

The Gravemind
""I am a monument to all your sins.""

"Gravemind: Do I take life or give it? Who is victim, and who is foe? Gravemind: Resignation is my virtue; like water I ebb, and flow. Defeat is simply the addition of time to a sentence I never deserved... but you imposed."
 * A God Am I- Though it's arguably the truth.
 * Assimilation Plot- The Gravemind keeps insisting that if it's allowed to carry out its plan, true peace will result. Right...
 * : It probably wasn't kidding when he told that.
 * Badass Boast- "I HAVE BEATEN FLEETS OF THOUSANDS! CONSUMED A GALAXY OF FLESH AND MIND AND BONE!"
 * There's not even a way to properly convey how much hate and anger is infused in that phrase in text. Even more amazing is that it's not bluffing...
 * Big Bad Ensemble: While separate antagonists, Gravemind and Truth make up the top villains for Halo 2 and Halo 3, though Gravemind is the more powerful threat.
 * Blue and Orange Morality: It's highly likely that the Gravemind doesn't even consider anything it does to be truly evil.
 * While that is never explicitly said, there are many allusions to it, particularly after it becomes clear to it that it has lost:
 * While that is never explicitly said, there are many allusions to it, particularly after it becomes clear to it that it has lost:

"Gravemind: I have the memories of many poets far beyond your limited human culture. And I have the quickness of intellect to compose all manner of poetic forms as I speak rather than labor over mere words for days."
 * To be specific, the Gravemind believes that it is the next step in evolution, and that the Flood is a gift he is giving any creature he consumes. This was his main weapon in turning Mendicant Bias: reminding him that his creators' religion revolved around embracing evolution and letting it have its way, painting them in a hypocritical light when they opposed the Flood.
 * Although, considering what we find out in Cryptum,.
 * Primordium straightens it out in the most non-straight screwed-up way possible. Apparently,  We can only hope the last novel clears it up.
 * Eldritch Abomination: An organic plant that represents the consciousness of the parasitic Flood, is he.
 * Evil Laugh: In Halo 3,.
 * Evil Sounds Deep
 * Galactic Conqueror: And unlike the most of them, it has already conquered at least one galaxy and now wants ours.
 * Gratuitous Trochaic Septameter
 * Hive Mind
 * I Am Legion
 * Large and In Charge: For a plant thing, the thing is the size of a city.
 * And in Halo 3, after turning High Charity into an extension of himself, it is a city, or rather, a moon.
 * A moon over twice the size of the Death Star, to be precise (300+ kilometers). And he was apparently present in a good portion of a Halo, able to grab both Chief and Arbiter when they're a good ways away from each other. Also, the described body is one of dozens. Or hundreds.
 * Large Ham: One of the most prominent examples in the series. Check out it's above Badass Boast for one of it's best.
 * Manipulative Bastard
 * Omnicidal Maniac
 * The Chessmaster: Chillingly evident when you consider that it always speaks in verse. Some poets spend years going over individual poems, where as the Gravemind is so intelligent it can improvise every word it speaks into a rhyme.
 * Time Abyss
 * Utopia Justifies the Means: Except he doesn't even believe that what he's doing is horrifying.
 * We Can Rule Together: it used this temptation on Mendicant Bias on how they were the superior races unlike the Forerunners and so have every right to conquer them. It worked, but Bias would later regret the offer.
 * Wicked Cultured: it speaks as if it writes poems. When Cortana asked it why it did so in Human Weakness, it simply said it was preference, as after having consumed many poets from different cultures, it grew fond of their gifts.

 * - In Halo 3,.

032 Mendicant Bias

 * The Atoner: When the Forerunners activated the rings, he regretted his alliance with the Flood and spent the last 100,000 years wishing to undo his actions. He attempted to finally atone himself by helping Master Chief offscreen on The Ark, even if he knows it wouldn't be enough to redeem himself.
 * Conflict Killer:
 * Face Heel Turn: Reversed 100,000 years later.
 * Fallen Hero: and he spent the last 100,000 years to become a hero again in the eyes of the "reclamiers".
 * Famous Last Words: "And so here at the end of my life, I do once again betray a former master. The path ahead is fraught with peril. But I will do all I can to keep it stable - keep you safe. I'm not so foolish to think this will absolve me of my sins. One life hardly balances billions. But I would have my masters know that I have changed. And you shall be my example."
 * The Ghost: His only physical appearence is through the Terminals as words..
 * Redemption Equals Death: He probably died when the Installation 04 (II)'s activation "did a number" on the Ark but it's still unknown if he did.
 * My God, What Have I Done?: When his Face Heel Turn ended up with the extinction of the Forerunners.
 * Nice Job Breaking It, Hero: First by helping the Flood against the Forerunners and many years later telling the Prophets of the relationship between the humans and the forerunners, provoking the Human-Covenant War.
 * There Is No Kill Like Overkill:
 * Unwitting Pawn
 * What You Are in the Dark: He spends the better part of Halo 2&3 trying to save humanity despite it being very likely none of them will ever know he existed.

The Rookie

 * Badass Normal
 * Heroic Mime
 * The Faceless
 * The Ishmael
 * Non-Indicative Name: While he is the newest member to join the squad, the Rookie's been in plenty of missions before and no one gets into the ODSTs without a lot of experience.
 * One-Man Army- Not as much as Master Chief, but still.
 * Rookie Red Ranger
 * Sleepyhead: does this whenever he's not kicking ass.
 * The Voiceless -Save for grunts, groans, and a whistle

Edward Buck

 * Deadpan Snarker- Occasionally.
 * Expy- Of Malcolm Reynolds. Not that that's a bad thing.
 * Hey, It's That Voice!- Nathan Fillion, of Firefly.
 * Last-Name Basis: Everyone calls him Buck, even his former girlfriend.
 * Ink Suit Actor
 * Slap Slap Kiss- With Dare.
 * Supporting Leader

Romeo (Kojo Agu)

 * The Casanova: Claims to be one. It's where his nickname comes from.
 * Cold Sniper- some of the cause of his jerkass traits.
 * Friendly Sniper
 * Ironic Fear: He's hinted to be afraid of heights.
 * Meaningful Name
 * Jerkass- A bit of one, yeah.
 * The Last DJ: His attitude would have gotten him kicked out of the military if it weren't for that fact that it's late in the war and his sniping skills are too valuable to ignore.
 * Team Prima Donna

Dutch (Taylor Miles)

 * As the Good Book Says...
 * BFG: Usually carries a Spartan Laser.
 * The Big Guy
 * Boisterous Bruiser
 * Hey, It's That Voice!- Adam Baldwin, of Firefly.
 * Religious Bruiser: Studied religion and philosophy in his college days.

Mickey (Michael Crespo)

 * Ace Pilot: He's not especially an amazing flier but it does take a good deal of skill to fly
 * Gosh Dang It to Heck- "Son of a gun!"
 * Hey, It's That Voice!- Alan Tudyk, of Firefly.
 * Rookie Red Ranger: He's been on the squad longer than the Rookie, but is a lower rank and has less battle experience. According to Buck, he still hasn't ever seen a glassing.

Veronica Dare

 * Action Girl- More so than Miranda Keyes.
 * Ink Suit Actress
 * Slap Slap Kiss- With Buck.
 * Hey, It's That Voice!- Tricia Helfer, of Firefly Battlestar Galactica.
 * Tsundere- Towards Buck.

Vergil

 * Actual Pacifist- doesn't stop him giving you energy shields, however.
 * Defector From Decadence- Effectively abandoned the Covenant when they strapped plasma bombs onto the peaceful, non-combative Engineers—for no apparent reason.
 * The Covenant did not want the neutral engineers to be captured by humanity and give them all their technical secrets, so they rigged them to explode when all the Covenant forces in the area die. In one of the novels, an engineer was killed by humanity after fixing Master Chief's armor so it could not take what it learned back to its Covenant fellows.
 * Starfish Aliens
 * The Engineer

Noble Six (SPARTAN-B312)
""Hyper-lethal... there's only one other Spartan with that rating.""


 * Ace Pilot: Apparently sometime before his/her assignment to Noble Team, Six was involved in the testing of an experimental shielded Space fighter called Saber. This seems to be there to justify him/her jumping into one of these craft during the course of the campaign, and taking the fight to the Covenant in orbit.
 * Badass
 * The Faceless
 * Featureless Protagonist: Unlike all the other members of Noble Team, his/her name, gender, and just about everything else is redacted, because he's a completely customizable character.
 * I Work Alone: Has a history of going solo in missions. Carter is quick to call him/her out on it.
 * One-Man Army: Along with Master Chief, the only spartan to be rated as "hyper lethal".
 * Sixth Ranger: The newest addition to Noble Team, and the player character.
 * The Quiet One: Hardly ever talks. Six does talk during some cutscenes in the actual game, and while not much, is still not completely silent. Having him/her silent in the first trailer seems to have been a cocktease.
 * You Are Number Six
 * The Quiet One: Hardly ever talks. Six does talk during some cutscenes in the actual game, and while not much, is still not completely silent. Having him/her silent in the first trailer seems to have been a cocktease.
 * You Are Number Six

Carter-A259

 * The Captain: He's described as a "born leader."
 * Commanding Coolness
 * My Greatest Failure: Mentioned as having "minor trust issues" after he blamed himself for the death of one of his men.
 * You Are Number One
 * My Greatest Failure: Mentioned as having "minor trust issues" after he blamed himself for the death of one of his men.
 * You Are Number One
 * You Are Number One
 * You Are Number One

Kat (Catherine-B320)
""In recognition of...her unparalleled brilliance, we honor her as the true genius of Noble.""


 * Artificial Limbs: Her right arm is mechanical. It's actually the first example in a Halo game.
 * Commanding Coolness
 * Curiosity Is a Crapshoot: Her superiors' opinion. It makes her excellent at information retrieval... including information they don't necessarily want her to have.
 * Deadpan Snarker
 * Hartman Hips
 * My Greatest Failure: Like Carter, she blames herself for the death of the previous Noble-6.
 * The Smart Guy: Good with computer systems and a brilliant tactician.
 * The Lancer: Best friends with Carter, and second-in-command of Noble Team.
 * Number Two: Literally.
 * The Squadette: The only female member of Noble Team (unless you make Noble Six one).
 * Voice with an Internet Connection
 * You Are Number Two
 * The Squadette: The only female member of Noble Team (unless you make Noble Six one).
 * Voice with an Internet Connection
 * You Are Number Two

Jorge-052
""In recognition of...his endless courage, honor him as the fighting spirit of Noble.""


 * Badass Baritone
 * Badass Beard
 * Boisterous Bruiser
 * Cool Old Guy
 * Cunning Linguist
 * Doomed Hometown: his homeworld is Reach... yeah...
 * Gentle Giant
 * The Heart
 * Lightning Bruiser: Noticeably more so than the other Spartans in the Halo Reach ViDoc "Once More into the Breach", where Jorge can be seen lugging his heavy machine gun around at the ready effortlessly, easily keeping pace with his smaller squadmates.
 * More Dakka: Wields a heavy machine gun as his primary weapon.
 * The Big Guy: He's the only Spartan-II on Noble Team, the rest of whom are slightly less powerful Spartan-IIIs.
 * Team Dad
 * You Are Number Five
 * Lightning Bruiser: Noticeably more so than the other Spartans in the Halo Reach ViDoc "Once More into the Breach", where Jorge can be seen lugging his heavy machine gun around at the ready effortlessly, easily keeping pace with his smaller squadmates.
 * More Dakka: Wields a heavy machine gun as his primary weapon.
 * The Big Guy: He's the only Spartan-II on Noble Team, the rest of whom are slightly less powerful Spartan-IIIs.
 * Team Dad
 * You Are Number Five

Emile-A239
""In recognition of...his warrior's spirit, we honor him as the merciless wrath of Noble.""


 * And This Is For
 * Anti-Hero: Type V.
 * Ax Crazy: Due to his "audacity" in the field, Emile's superiors are often reluctant to deploy him against human insurrectionists.
 * Token Evil Teammate: His antics are so bad that it is recommended that he be yanked off of the team in the event that they have to go up against human enemies, for fear of giving the insurrectionists 'ammunition' to use against the UNSC.
 * Blood Knight


 * Expy: Lots of comparison goes up between him and Ghost, as both have skull masks and act as the angry support staff. Although
 * The Faceless
 * Four Is Death
 * It Has Been an Honor
 * Knife Nut: In the trailer, his only significant role is sharpening his knife, which is ordinarily visibly strapped to his shoulder, on his armor. It seems to be his Signature weapon, alongside the Shotgun.
 * Kukris Are Kool
 * The Lancer: Subverted. He seems to fit the role, being the edgy/cool one and all, but his relationship with Carter never seems to be more than respectful obedience.
 * Military Maverick
 * Psycho for Hire
 * Scary Black Man: His accent, voice actor, and a semi darkened image in Halsey's lab suggest Emile is African, and he's definitely the scariest member of the team.
 * Short-Range Shotgun
 * Skeletons in the Coat Closet: Okay, he doesn't literally wear bones, but he has a skull etched into the face of his helmet. One wonders how he sees out of the thing, though he only scraped off the reflective gold coating. Presumably, the actual visor is made of a tough enough material to not be seriously damaged.
 * Sociopathic Hero
 * Vitriolic Best Buds: With Jorge.
 * You Are Number Four
 * You Are Number Four

Jun-A266
""In recognition of... his tireless diligence, we honor him as the vigilant eye of Noble.""


 * Cold Sniper/Friendly Sniper: Described as chatty, and comes across as friendly enough, but his last psychological evaluation also describes him as having an "unhealthy emotional detachment in regards to the consequences of his actions", though Colonel Holland disagrees with this assessment.
 * Mission Control
 * There Are No Therapists: Averted; he's undergone therapy for post-traumatic stress disorder, and hasn't relapsed.
 * What Happened to the Mouse?
 * You Are Number Three
 * You Are Number Three

Thom-B293

 * Badass: Just watch the Deliver Hope trailer. Just watch it. And then consider, he took a portable nuke aboard a Covenant Battlecruiser while it was landing troops. In such low orbit, it was clearly vulnerable and would be heavily guarded from within. Who knows how many Covenant he fought through aboard the Battlecruiser to get the nuke to the vehicle hanger?
 * Big Damn Heroes: Died before the game took place pulling one of these.
 * Heroic Sacrifice: How he died, ferrying a portable nuke to a Covenant Battlecruiser and letting it detonate with him still aboard.
 * Leeroy Jenkins: Colonel Holland considered him to be a blatant example. He was wrong.
 * One-Scene Wonder: In essence. We only see him in the trailer for Reach, we never hear him talk, but it's quite apparent from the trailer that Thom had some serious balls and was probably as awesome as he is made-out to be.
 * You Are Number Six

Captain James Cutter

 * A Father to His Men
 * Officer and a Gentleman
 * The Captain

Sergeant John Forge

 * Badass Family- Service in the military is a centuries-long tradition in his family, dating back to World War II, so this trope must be one of the reasons why he was able to.
 * Badass Normal-
 * Belligerent Sexual Tension: With Anders.
 * Hey, It's That Voice!: His voice actor also provides vocals for Nathan Drake and Deadpool.
 * I Call It Vera: Refers to his combat knife as "Lucy".
 * Sergeant Rock
 * Sergeant Rock

Professor Ellen Anders

 * Belligerent Sexual Tension: With Forge.
 * Damsel in Distress
 * Hot Scientist
 * Rage Against the Mentor: Has expressed her hatred of Catherine Halsey, whom she studied under, on several occasions.

Serina

 * Deadpan Snarker- Hoo boy...
 * Voice with an Internet Connection

Arbiter Ripa Moramee

 * Ambition Is Evil: After he got too powerful, he attempted to overthrow his clan's leaders, but got locked up. When he became the Arbiter, he gave this trope a new ugly face.
 * Ax Crazy: or Plasma Sword Crazy.
 * The Dragon: To the Prophet of Regret, much to the Covenant's warriors' grief.
 * Evil Counterpart: To the Brute Army Commander, surprisingly.
 * General Ripa: Sorry.
 * Hair-Trigger Temper: Oh yea. Just saying the wrong words or advices will make him pissed.
 * Hot-Blooded: More then the rest of the Elites, but it comes more likely from his psychopathic disorder reather from religious fanaticism.
 * Large and In Charge
 * Large and In Charge: Huge, even for an Elite.
 * Psycho for Hire
 * The Berserker
 * The Brute: Ironic, considering his species.
 * Goes into Personality Swap Territory when you read the backstory of the Multiplayer-only Brute Army Commander.
 * We Have Reserves
 * We Have Reserves

SPARTAN Red Team (Douglas-042, Jerome-092, and Alice-130)

 * Action Girl: Alice.
 * Badass Boast: "War Is Hell. And I'm the Devil."
 * Badass Crew: They're Spartans, so its a given.
 * The Captain: According to Halsey's Journal, both she and CPO Mendez identified Jerome as one of the four emerging leaders of the Spartan-IIs. The other three were John, Fred, and Kurt.
 * Curb Stomp Battle: Against the Elites at the end of Halo Wars. Given that those Elites were probably Honor Guards, it's just more awesome.
 * It Has Been an Honor:
 * Powered Armor: MJOLNIR Mark IV, which lacks the shields players are so used to.

Fred-104

 * Super Soldier Spartan-II
 * Cyborg
 * Powered Armour
 * Super Strength
 * Jack of All Stats
 * Knife Nut He's very good with combat knives.
 * The Lancer
 * Overshadowed by Awesome Fred frequently came in second or third during tests. It's heavily implied that this was intentional on his part.
 * Overshadowed by Awesome Fred frequently came in second or third during tests. It's heavily implied that this was intentional on his part.

Will-043

 * Determinator: John credits him as a one, citing that Will "never failed to complete a mission."
 * Made of Iron: The fact that he is testament to his toughness.
 * Super Soldier: Spartan-II
 * Cyborg
 * Powered Armour
 * Super Strength: Actually managed to physically tear a Hunter apart.

Kelly-087

 * Determinator- Has insisted on fighting even when horribly injured (even by Spartan standards.)

 * Lightning Bruiser- The fastest of the Spartans.
 * Super Soldier- Spartan-II.
 * Cyborg
 * Powered Armour
 * Super Strength

Linda-058

 * Back from the Dead- Well, she was clinically dead after the Battle of Reach.
 * Canon Immigrant: An Easter Egg in Anniversary includes a computer display at the cryo room noting her clinically dead status.
 * Cold Sniper
 * Green Eyed Red Head
 * Improbable Aiming Skills: Taken Up to Eleven, she once sniped two targets so fast that John had no idea who she shot first. Fred and John have both noted that she makes sniping an art.
 * Lone Wolf: John feels that this applies to her more than any other Spartan, and that it makes her the strongest of them.
 * Super Soldier- Spartan-II
 * Cyborg
 * Powered Armour
 * Super Strength
 * The Quiet One- Even moreso than John-117.
 * The Spymaster- According to Halsey's journal, Linda was running an intelligence network among her classmates to spy on her teachers before conscription. Please remember that she would have around six years old at the time.

Samuel-034

 * The Big Guy- Huge, even for a Spartan-II
 * Defeat Means Friendship- How he, John, and Kelly became friends.
 * Actually, this trope is inverted; When they first meet, John goes lone wolf on Sam and Kelly in a situation requiring teamwork and they end up losing. Sam comes within a hair's breadth of beating him up the next day. Fortunately for John, he improvises a much better plan that gets them working together and winning the scenario, and then they become friends.
 * Super Soldier- Spartan-II
 * Cyborg
 * Powered Armour
 * Super Strength
 * Super Strength

Grey Team (Jai-006, Adrianna-111, and Mike)

 * Ace Pilot- Mike, who learned how to pilot a Pelican at six just by watching someone else fly one.
 * Action Girl- Adrianna may edge out Kelly and Linda. She didn't try to escape because she wanted to go home, she did it for the thrill.
 * Badass Crew- They're Spartans.
 * Bald of Awesome- Mike
 * Enfante Terrible- At age six, Jai and Adrianna's escapes were so violent that the security guards had to start tranquilizing them from Pelicans for fear of losing limbs.
 * Super Soldier
 * Cyborg
 * Powered Armor
 * Super Strength
 * What Happened to the Mouse?- Mentioned to have been out of contact for almost a year by the time of The Fall of Reach. They've been known to go under for long periods, but it's never been addressed if where they are.

Black Team (Black-One, Black-Two, Black-Three and Victor-101 AKA Black-Four)

 * Action Girl- Black-One and Black-Two.
 * Cold Sniper- Victor-101.
 * The Big Guy- Black-Three, the heavy-weapons specialist.
 * The Smart Guy- Black-Two, the intelligence specialist.
 * You Are Number Six

Kurt-051

 * Commanding Coolness
 * Faking the Dead- ONI Section Three did so to recruit him to help train the Spartan-III program.
 * Genius Bruiser- Some of the things he did while running the S-III program are a reminder that S-II's are really all deadly and adaptable individuals.
 * Spider Sense- To an extent; he gets "a bad feeling" once that promptly allows him to save John & co. from an ambush.
 * Super Soldier- Spartan-II
 * Cyborg
 * Powered Armour
 * Super Strength
 * The Men First
 * Powered Armour
 * Super Strength
 * The Men First
 * The Men First

Tom-B292

 * Super Soldier- Spartan-III
 * Cyborg
 * Laser Guided Tykebomb
 * Powered Armour- Not as tough as the Spartan-II armor.
 * Super Strength- Not as strong as the Spartan-IIs.
 * The Lancer- To Kurt-051.

Lucy-B091

 * Broken Bird- Glasslands takes a look at just how awful her post-traumatic stress has become.
 * Dumb Struck- Post-Traumatic Vocal Disarticulation, an aftermath of seeing 298 out of her 300-soldier force die during the mission on Pegasi Delta.
 * Famous Last Words- "How are you sure we're alive?"; granted, she isn't dead, but these were still the last words she ever spoke.
 * Super Soldier- Spartan-III
 * Cyborg
 * Laser Guided Tykebomb: The SPARTAN IIIs were chosen from orphans to destroy space aliens, and it seems that's what they did most of the time.
 * Powered Armour- Though not as tough as the S-II armor.
 * Super Strength- Not as strong as the Spartan IIs
 * The Voiceless -
 * Waif Fu- One of the physically smallest of the Spartan-IIIs, but being a Spartan implies that she almost-certainly has superb close-combat training.

Doctor Catherine Halsey

 * Despair Event Horizon- Following the Fall of Reach, the discovery of Halo and the Flood, and learning that the Covenant has found Earth, Halsey becomes convinced that the UNSC cannot win the war, and decides to take the Spartan-IIs (and as many Spartan-IIIs as she can) somewhere safe where they can wait out the war. What she failed to realize is how effective a team John and Cortana were.
 * Hot Scientist- Zigzagged because of her age.  However, it also said that Cortana's looks are based on her younger self, and The Fall of Reach describes her as "lovely - not beautiful, but definitely a striking woman".
 * I Did What I Had to Do: Her initial justification for the Spartan-II Program.
 * Jerk with a Heart of Gold: Her actions in the Spartan Program and her often cold, dismissive exterior may throw people off, but she is a genuinely caring person struggling with her own morals.
 * In Glasslands, the central human protagonists have a much more negative opinion on her, ranging from Jerkass (Spartan III's) to a Complete Monster who crossed the Moral Event Horizon a long time ago (Chief Mendez and the ONI team under Serin Osman).
 * My God, What Have I Done?- Eventually, her reaction to the Spartan-II program.
 * Omnidisciplinary Scientist- Over the course of the series, she's shown herself to be an expert in medical science, artificial intelligence, xenoarchaeology, mechanical engineering, and quantum physics. You name it, she's probably an expert in it.
 * Parental Substitute- To the Spartan-IIs
 * Rapid-Fire Typing- 120 words-per-minute.
 * Sore Loser: She does not take kindly to being intellectually bested.
 * Teen Genius- Was working on her second doctoral thesis at age 15.
 * Well-Intentioned Extremist
 * Teen Genius- Was working on her second doctoral thesis at age 15.
 * Well-Intentioned Extremist

Senior Chief Petty Officer Franklin Mendez

 * Badass Grandpa- By 2552, he was still capable of keeping up with the Spartans, who have come to the conclusion that regular Marines and Army troopers a quarter of his age couldn't keep up with them.
 * Bald of Awesome- Shaves his head.
 * Cool Car- A custom rocket warthog.
 * Determinator- He not the type of man who surrenders. And he made sure the Spartans were the same.
 * Drill Sergeant Nasty- But only because it's his job.
 * Parental Substitute- To the Spartan-IIs.
 * Smoking Is Cool

Colonel James Ackerson

 * Colonel Badass
 * Jerkass
 * Lack of Empathy- Was actually glad Reach was glassed in the hopes that Dr. Halsey and the Spartan-IIs were killed. And that's not even getting started on the Spartan-IIIs.
 * Pet the Dog-
 * We Have Reserves- In his own words, the Spartan-IIIs are meant to "trade lives for time".
 * Pet the Dog-
 * We Have Reserves- In his own words, the Spartan-IIIs are meant to "trade lives for time".

Admiral Preston James Cole

 * Badass
 * Badass Bookworm: Kept up on his reading on theoretical physics and military history while retired.
 * Four-Star Badass: He was this before the Human-Covenant War. Afterward, he got even more badass.
 * Retired Badass: After
 * Dying Moment of Awesome: He lures the Covenant fleet at the gas giant Psi Serpentis to attack his flagship,
 * Heroic BSOD: Upon learning that
 * Shotgun Wedding: Twice, but the first time he wasn't actually the father.
 * The Strategist
 * The Strategist

Vice Admiral Margret O. Paragonsky

 * Even Evil Has Loved Ones: Genuinely cares about Serin. Bear in mind, she's one of the few people Paragonsky does care about.
 * Evil Old Folks: Extra emphasis on the old. She's over 90 years old by the 2552, and still running ONI.
 * Ice Queen
 * Kick the Dog: Planned on telling Halsey that her hated rival Ackerson had died a hero, but only after informing her of.
 * Which helps add to her being so unlikable: while Halsey did all of her controversial projects fully dedicated to the welfare of humanity, Ackerson was all about his own personal gain. The reason why Parangosky likes him better, though, basically boils down to Halsey being smarter than her.
 * The Spymaster: The head of ONI.
 * Stop Helping Me!: Her idea to make sure the Sangheili don't pose a threat to the UNSC? Start a Civil War among while the rest of the UNSC is trying to make a peace treaty with them. The potential blowback is phenomenal.
 * Not only that, they're planning a civil war by helping an uprising against the Arbiter, who is traveling around the entire homeworld to different states convincing them, among other things, to let the war with the humans go because they have more important things to do. It's the equivalent of Country A helping kill the primary candidate for Country B's leadership whose foremost policies call for peace with Country A, when the runner-up is a blatant anti-Country A supporter.
 * "The Reason You Suck" Speech:
 * We Have Reserves: Authorized the creation of three companies of Laser Guided Tyke Bombs to serve as Cannon Fodder.

The Didact
""The peaceful one is at war without and within""


 * The Atoner: He shares a lot of this with the Arbiter, except he
 * Four-Star Badass
 * A Father to His Men: Literally: his children served under him in the . They were killed, however, which gives us a hint to one of the reasons he thinks...
 * Humans Are the Real Monsters: Humanity  hasn't painted us in the best light for him. Some subspecies he likes, though: namely, the ones that do what they're told. However...
 * Humans Are Warriors: He has some respect for us, and certainly thinks we're above the bestial image most Forerunners have of us.
 * King in the Mountain: When into a Cryptum to avoid political censure.
 * Large and In Charge: He could dwarf most Elites, Brutes, and Hunters. The protaganist (a younger Forerunner) mentions that his shoulders are as far apart as his outstretched arms.
 * Sealed Good in a Can: The aforementioned Cryptum.
 * Star-Crossed Lovers: With the Librarian, quiet literally. Thanks to the Flood, the amount of time they have together is very minimal, considering how long they've been married.
 * The Stoic: A given for most mature Forerunners; his default expression is either sad or solemn. However...
 * Not So Stoic: He smiles slightly when Bornstellar mentions that "Someone saw his potential through his flaws". It's a bit of a heartwarmer.
 * Worthy Opponent:
 * Worthy Opponent:

The Librarian
""I am close. Close to saving them all.""


 * Heroic Sacrifice: Destroyed her keyship, preventing her from getting back to the Ark and forcing the Didact to activate the Halo Array.
 * Hot Scientist: Well, beautiful scientist. Even Chakas, a human, thinks she's the most beautiful female he's ever seen.
 * The Messiah: As a Lifeworker, she loves every living thing.
 * Only Sane Woman: Among the Forerunners. She recognizes that the Halo Array is a horrible weapon, and takes steps to preserve life in the event it is used, but at the same time, she also sees that there is no other way to defeat the Flood.
 * Star-Crossed Lovers: With the Didact.

Forthencho, the Lord of Admirals

 * Defiant to the End: Despite their best effort, Forerunners couldn't get any useful information from him.
 * Four-Star Badass: Under Forthencho's command, defenders of Charum Hakkor with inferior technology and dwindling number managed to beaten back attack after attack of Forerunner Armada under the command of Didact himself for years. At the end, Forerrunners were forced to use Brute force approach and accept terrifying loss to take the planet.
 * Revenge Before Reason: For all his respect to Forerunner's Warrior-Servants, He would do everything to bring down the Forerunners at any cost.
 * Worthy Opponent: Warrior-Servants as a whole and especially Didact. The feeling is actually mutual.

Fal 'Chavamee

 * Asskicking Equals Authority
 * One-Man Army: He wouldn't have reached Arbiter without being one.

Hauser

 * Black Dude Dies First: Averted, he's the only marine that survives from his team
 * Catch Phrase: "Just ain't my day".

Ghost

 * From a Certain Point of View: His creative interpretation of his orders.
 * Redemption Equals Death
 * Powered Armor

O'Brien

 * Cold Sniper/Friendly Sniper: Switches between these two personalities.
 * Jerkass: The way he talks to Cal-141.

Cal-141

 * Cold Sniper
 * The Quiet One
 * The Reveal:

Daisy-023

 * Cloning Blues
 * No One Gets Left Behind:.
 * You Can't Go Home Again
 * You Can't Go Home Again

Thel 'Lodamee

 * Hot-Blooded: According to The Fall of Reach, his bloodthirstiness worries his commander.
 * Honor Before Reason: When he finds the Master Chief out of ammo, he tosses an extra energy sword to him so they could duel it out.
 * Large Ham: "I had him! Commander, you fool! A THOUSAND HELLS AWAIT YOU!"
 * Retcon: Was originally supposed to be Thel 'Vadamee (the Arbiter of the Halo trilogy) but this was changed in the 2010 rerelease of The Fall of Reach.

SPARTAN-1337

 * Chew Toy: He fits this trope like a glove. The Master Chief lampshades that this sort of thing happens to him all the time.
 * Determinator: And yet he has a fighting spirit Kamina would be proud of.
 * Hot-Blooded: Very.
 * Large Ham: Forget the Elites. 1337 has the ability to chew the scenery with a helmet. And he's a Spartan!

United Nations Space Command (UNSC)

 * Civil War: Was beginning to tear itself apart before the Covenant gave Humanity a reason to unite.
 * The Federation
 * Humans Are Warriors: It's due to the Humans' guts and will alone that they did so well and survived so long in the Human-Covenant War. Many Covenant warriors (especially the Elites) lampshade it, and some even believe they've earned the right to join the Covenant. This trope and their relationship with the Forerunners is also the reason why the Gravemind wants to finish them first before he finish the Covenant.
 * Kinetic Weapons Are Just Better
 * Proud Warrior Race Guys: Well you can say that. The Humans were the first species to give The Covenant a real fight and they were the ones who won the war.
 * Rock Beats Laser: At least on the ground, the humans' ballistic weapons are somewhat more effective than the Covenant's plasma weapons. In space, it's different.
 * The War of Earthly Aggression: Before the Human-Covenant war, the UNSC ran the risk of splintering under the weight of rebellions.
 * The War of Earthly Aggression: Before the Human-Covenant war, the UNSC ran the risk of splintering under the weight of rebellions.

Insurrectionists

 * Dying Like Animals: From believing the Covenant might be better than the UNSC to still fighting the UNSC after the destruction of the Outer Colonies.
 * Ironic Nickname: Insurrectionists were called "Innies" by the UNSC, despite desperately wanting "out" of the UNSC.
 * Pet the Dog: They helped evacuate a lot of the colonists from Madrigal prior to its glassing.
 * The Revolution Will Not Be Civilized- There was a lot of sympathy for the planets wanting autonomy from Earth and the UNSC, but extremists eventually started employing terrorist tactics, destroying their standing.
 * Your Terrorists Are Our Freedom Fighters
 * Your Terrorists Are Our Freedom Fighters

SPARTAN-II Program

 * All of the Other Reindeer: The Spartans are considered freaks by some of the more bigoted humans. For the most part, though, the average human is more than grateful to see a Spartan on the battlefield.
 * Bio Augmentation: Those who weren't killed received unbreakable bones, enhanced strength, senses, and reflexes. Unless you were one of the unfortunate ones.
 * Celibate Hero: One of the side effects of the augmentations was that the Spartans have a lack of interest. The only Spartan to actually try was Maria-062.
 * Child Soldiers: They were abducted at ages 6 or 7, and were given their augmentations at age 14.
 * Genius Bruiser: The Spartans were trained to be both the ultimate soldiers and highly intelligent ones.
 * Interservice Rivalry: With the Orbital Drop Shock Troopers.
 * Only One Name: The Spartans only kept their first name, while their service numbers are the number which they were listed on Halsey's candidate list. Since they were "conscripted" at age 6, none of them remember their last names.
 * Powered Armor: MJOLNIR armor is used exclusively by Spartans. Anyone else who uses them would end up crippled.
 * The Spartan Way
 * Super Prototype: To the Spartan-III
 * Super Soldier
 * True Companions: The Spartans grew up together during their training, and always know that they can rely on them.
 * Tyke Bomb

SPARTAN-III Program
""Consider the SPARTAN-II's a proof-of-concept prototype. Now it is time to shift into production mode. Make the units better with new technology. Make more of them. And make them cheaper.""
 * Bio Augmentation: Not as strong as the Spartan-IIs, but still very strong, and with a much higher survival rate.
 * Child Soldiers: Some even younger than the Spartan-IIs.
 * Doomed Hometown: The Spartan-IIIs are war orphans whose families were killed when the Covenant glassed their planet.
 * Powered Armor: Subverted with the Semi-Powered Infiltration Armor, which provides no physical enhancements. Played straight with those that got MJOLNIR armor.
 * Revenge: Why they joined up.
 * The Spartan Way
 * Suicide Mission: What they were sent on.
 * Super Prototype: The mass-produced version of the Spartan-II, created by Colonel James Ackerson.


 * Super Soldier
 * True Companions: Like the Spartan-IIs. Although at first, there was concern that Alpha Company would end up killing each other during training.
 * Tyke Bomb
 * Laser Guided Tykebomb: Composed by orphans from glassed colonies. While pitted occassionally against the Insurrection, the main difference between the Spartan-II and the Spartan-III, is that while the II's were marked as "the Protectors of Earth and all her Colonies", the III's are disturbed and traumatized children that care for nothing except revenge.
 * Zerg Rush: Their main tactic in the final missions they are sent to. None of them are expected to survive.

Orbital Drop Shock Troopers (ODST)

 * Badass Normal: Considered the second most hardcore soldiers in the UNSC after the Spartans. But don't mention that last part to their face.
 * Badass Creed: "Jump feet first into hell."
 * Interservice Rivalry: With the Spartan-IIs. It's more of an ODST thing than a Spartan thing.
 * It's Raining Men: From orbit.

UNSC Marine Corps

 * Badass Normal: Can sometimes take down a stronger opponent by themselves. Especially in-game starting with Halo 2 and peaking in Halo 3.
 * Drives Like Crazy: In every game. Seriously, they are supposed to be a professional force of trained soldiers and yet they drive as if they're both blind and drunk.
 * Redshirt Army
 * We Will Wear Armour in The Future

Office of Naval Intelligence (ONI)

 * Government Conspiracy: Several going on at once.
 * He Who Fights Monsters: ONI's goal is the preservation of humanity, but they do some very questionable things to achieve it.
 * In-Series Nickname/Fun with Acronyms: Oni (as in, the Japanese demon); also, "Spooks"
 * Propaganda Machine: The whole purpose of ONI Section II.
 * Properly Paranoid: Actually subverted. By 2552, they're just overly paranoid of their personnel.
 * Right Hand Versus Left Hand: Oh, god, they play this hard.
 * The Spook
 * State Sec: They have elements of this.

Artificial Intelligence

 * A.I. Is a Crapshoot: Smart AIs have a chance to go rampant after seven years.
 * Sliding Scale of Robot Intelligence: There are 2 kinds of Human AIs: Dumb AIs, who, despite the name, are very smart, but cannot learn, and Smart AIs, like Cortana, who can learn. The Forerunner's Dumb AIs are on par with human Smart AIs. One example is 343 Guilty Spark. The Smart ones are amazingly smart and powerful, but have the risk of rampancy.
 * Virtual Ghost: Smart AI's are created from brains from deceased donors.

The Covenant

 * Church Militant
 * Defeat Means Friendship: It's tradition for the Covenant to allow defeated foes to join their ranks. By that way their military is getting greater by each conquest. The Grunts, the Hunters and the Drones are examples of species who had been in war against the Covenant, lost and joined their ranks as an alternative for being nuked to extinction. It's the reason why the Elites are confused about why the Prophets don't let the Humans join the Covenant as well.
 * Death From Above: Glassing.
 * The Empire
 * Enemy Civil War
 * Five-Bad Band: Loosely.
 * Big Bad: The Prophets.
 * The Dragon: Elites and Brutes.
 * The Evil Genius: Engineers, Jackals, and Skirmishers.
 * The Brute: Well, Brutes. Also Hunters.
 * The Dark Chick: Grunts and Jackals.
 * Fantastic Racism: Due partially from the caste system, the other half being their subjugation
 * Frickin Plasma Bolts
 * Scary Dogmatic Aliens

The San 'Shyuum (Prophets)
(Perfidia Vermis )
 * Exclusively Evil: No Prophet with any sympathetic motives has been shown.
 * Subverted by Halo: Cryptum, which had the Prophets as the allies of the technologically advanced ancient human civilization
 * Cool Chair: Gravity thrones. The higher you ascend in the Covenant hierarchy, the cooler your chair gets.
 * Going by the Prophet of Regret's fight in Halo 2, a gravity throne can fly, teleport, deflect nearly anything with its shields, and has twin laser beams mounted on it.
 * Ah, but he was a Hierarch, who would have the absolute best thrones available.
 * Depopulation Bomb: With the destruction of High Charity and sterilization of infected ships at Delta Halo, only a handful remain. However, the Beastarium implies that the Prophets' claim that their homeworld was destroyed by a stellar collapse might be false, since they seem very shy about saying where it was.
 * Dysfunction Junction: None of the High Prophets seem to get along too well.
 * Which is ironic, as The Cole Protocol indicates that to even suggest this is heresy.
 * The Fundamentalist
 * Irony:.
 * Kill All Humans
 * The Masquerade/Ancient Conspiracy:
 * Meaningful Name: The Bestiarum gives their scientific name as "Perfidia Vermis," meaning "Treacherous Worm".
 * The Mothership: High Charity.
 * Omnicidal Maniac
 * Planet of Hats: They're all devious and slippery. Back in the day (of the Forerunners), they're hat was this combined with being Green Skinned Space Babes.

The Sangheili (Elites)
(Macto Cognatus )
 * Arch Enemy: ( the Humans, The Brutes;, The Flood)
 * Authority Equals Asskicking: It wouldn't come as a surprise. After all...
 * Asskicking Equals Authority
 * Elite Mooks: Zealots
 * Genius Bruiser: Twice as strong as an average human and just as smart.
 * Heavyworlders
 * Honor Before Reason: They would rather die than use a human weapon because it would be "heresy"..
 * Interservice Rivalry: With the Brutes
 * Large Ham: Just about every single one of them.
 * Laser Blade: Energy swords, which are just as much symbols of rank as they are weapons.
 * Lightning Bruiser: They're just as agile and fast as they are strong and smart.
 * Meaningful Name: Sangheili consider all names meaningful, with the more names you have meaning the more important you are. They actually forbid the Grunts and Jackals from having more than one name, and are disgusted by humanity's cavalier approach to naming things.
 * Not So Different: With the Humans. Some of them even lampshade it..
 * Planet of Hats: They all love combat, discipline, and honor.
 * Proud Warrior Race Guy
 * Space Romans: Think Imperial Japan IN SPACE!
 * Super Strength
 * Worthy Opponent: Some of them seem to consider humanity as this near the end. One even vocally wonders why the Prophets are bent on wiping them out, when they could be very useful additions to the Covenant.
 * Super Strength
 * Worthy Opponent: Some of them seem to consider humanity as this near the end. One even vocally wonders why the Prophets are bent on wiping them out, when they could be very useful additions to the Covenant.

The Jiralhanae (Brutes)
(Servus Ferox )
 * Exclusively Evil: At least the Elites had a few semi-decent characters...
 * There might be one—count it, one—exception seen thus far. The Brute Commander on Harvest had apparently gained respect for humanity's courage and appreciation for their differences.
 * Ironically, the same game's Sangheili Arbiter is a raving whirlwind of violence who doesn't care for honor or pride. Go figure.
 * Maccabeus (the Brute Chieftain from Contact Harvest) also seemed to genuinely worship the Forerunners without blindly following orders.
 * Asskicking Equals Authority: See Klingon Promotion.
 * Bayonet Ya: Brute weaponry lives off this. Every native Brute weapon is armed with bayonets. Even the Gravity Hammers are bladed.
 * The Berserker: Destroy their armor and they start rampaging, an act which is actually called "berserking".
 * Boss in Mook Clothing: The Chieftains.
 * The Brute: Duh.
 * Drop the Hammer: Gravity Hammers. Like the energy sword, it's based off of ceremonial weapons.
 * Elite Mooks: Chieftains.
 * Grenade Launcher: The Brute Shot, a grenade launcher with a huge bayonet on it. That says all you need to know about Brute combat mentality.
 * Heavyworlders
 * Interservice Rivalry: With the Elites
 * Killer Space Monkey
 * Klingon Promotion: Brute society runs on this... more psychotic version of this Trope. A Brute killing his own Chieftain makes him the Chieftain of his tribe (Or race, in the case of Tartarus). Every time this happens, however, the Brutes fight over the right to lead.
 * Lightning Bruiser: Once they go berserk, you often don't realize it before they are all over you.
 * Nail'Em: The Brute Spiker, a rifle which shoots heated spikes at its opponents.
 * Nerf: Justified. In Reach, only the Chieftains have energy shields, and those are relatively weak compared to the shields used by similarly high ranking elites. On the other hand, more of them carry Gravity Hammers, and their Spikers pack a bit more of a punch.
 * Not So Different: With the Humans too. Both are primate warrior species with a great deal of creativity and savagery.
 * Proud Warrior Race Guy: A particularly psychotic type.
 * Roaring Rampage of Revenge: When the members of a Brute pack are killed, the last one usually goes nuts and tries to bash you with their hands.
 * Spikes of Doom: Brutes love to weaponize spikes. Their signature weapon after the Gravity Hammer and Brute Shot are Spiker Rifles, which shoot burning spikes at an opponent, and the spike grenade, a grenade which to humans appears the size of a club and shoots spikes in every direction upon exploding.
 * Super Strength: Can match or ''surpass' a Spartan.
 * To Serve Man: Will gladly eat prisoners.

The Unggoy (Grunts)
(Monachus Frigus )
 * Bilingual Bonus: Their species name is Tagalog for "monkey;" the names for their home star, home world, and one of its moons are also in Tagalog.
 * Butt Monkey: They take a lot of abuse.
 * Cannon Fodder
 * Dirty Cowards: Until Halo 3, when the Brutes started leading them. Suffice to say, having a commander who makes a game of ripping apart POW's provides a bit more motivation than having a stern but Reasonable Authority Figure.
 * Explosive Breeder: Can go from hundreds to hundreds of thousands in a few short years according to The Cole Protocol. It's mostly a survival method: The Grunt homeworld Balaho is a planet with two winters and naturally occurring pillars of fire, and they were still at the risk of extinction. Ironically, being forced into the Covenant saved them from extinction, but warfare is the only thing that can put a dent in their numbers.
 * Gas Mask Mooks: Justified, as they breathe methane, so the oxygen everyone else breathes would kill them. On the other hand, they are the weakest enemies.
 * Heroic Neutral: The Grunts will protect themselves and their own, but otherwise, they just want to be left alone.
 * Hulk Speak
 * Ineffectual Sympathetic Villain
 * Interservice Rivalry: With the Jackals.
 * Losing the Team Spirit: "Leader dead! Run away!!"
 * Until Halo 3 and subsequent games, where insted of panicking, some of them will draw twin plasma grenades and suicide-rush you.
 * Punch Clock Villain: They're just Slave Mooks who are forced to fight the humans. If they were allowed to choose for themselves, they whould rather stay out of the war completly.
 * Slave Mooks
 * Stout Strength: Stronger than they look, judging by the heavy equipment they're sometimes seen carrying.
 * Taking You with Me: Suicide bombers in 3, ODST, and Reach, and the Suicide Grunts in Halo Wars.
 * Took a Level in Badass: In Halo 3. Instead to run away as they did in the former games, they usually decide to blow themself up in order to kill the Chief. Just listen to their new war cries, it's scary.
 * In-universe, this happened during the Grunt Rebellion, where the Grunts showed the Covenant that they were fully capable of fighting off highly trained warriors with sheer numbers and determination. The Elites response to said rebellion? Give them proper training and real weapons.
 * To Serve Man: During the Battle of Draco III, they were set loose to devour the prisoners the Covenant had captured.
 * Occasionally you may hear some mutter in their sleep: "If hungry, eat Jackal."
 * You No Take Candle
 * Zerg Rush

The Kig-Yar (Jackals and Skirmishers)
(Perosus Latrunculus )
 * Cannon Fodder: Less so than the Grunts.
 * Cold Sniper
 * Feathered Fiend: Well, at least we think they're birds... and apparently, according to her journal, so does Dr. Halsey.
 * Played much straighter with the Skirmishers, who actually have feathers.
 * Fragile Speedster: The Jackals are very fast, but very vulnerable, which is why they're carrying shields. Subverted with the Skirmishers, however, who are Made of Iron Speedsters.
 * Hired Guns: Only in the Covenant because they're on the Prophets' payroll.
 * Hot-Blooded: "Too bloodthirsty" to be expert snipers.
 * Interservice Rivalry: With the Grunts
 * Luckily, My Shield Will Protect Me
 * Planet of Hats: They're all pirates at heart.
 * Punch Clock Villain: Borderline case. They're only in the war for the money, but a lot of them are cruel and violent anyway. Nonetheless, a colony of Kig-Yar in The Cole Protocol happily coexisted in a trade relationship with humans until the Covenant forced them to turn on the humans.
 * There were some who regreted it, though, as they felt a kinship with the rebels and pirates of the Rubble. Even Reth seems to regret it a bit, but knows there's no backing down.
 * Remember the New Guy?: The Skirmisher subspecies has apparently been in the war the entire time.
 * According to Bungie, nearly every Skirmisher left was stationed on Reach during the battle. And we all know how that turned out.
 * Sinister Scimitar: While it doesn't appear in the games, in the novels Jackals often use energy cutlasses, swords where the blade comes off after hitting flesh and then exploding in the target. It's probably based off the needler.
 * Space Pirates: Not all, but a bunch of them are privateers.
 * To Serve Man: Confirmed in Halo: Evolutions to eat humans if given the chance.
 * To Serve Man: Confirmed in Halo: Evolutions to eat humans if given the chance.

The Mgalekgolo (Hunters)
(Ophis Congregatio )
 * Arm Cannon: Sometimes it's a Frickin' Plasma Beam, other times it's just a Grenade Launcher. Depends on the game.
 * Bash Brothers: Always come in pairs.
 * BFG: See Arm Cannon above.
 * Blue and Orange Morality: The Hunters' motivations are completely alien, even to the rest of the Covenant. They intentionally reinforce their image of strangeness to ensure the other members of the Covenant leave them alone.
 * Boss in Mook Clothing: In Halo 3, they're significantly tougher than in Halo 1.
 * They're about as strong in Reach and have higher ranks....and are seen in packs.
 * The Brute: Not Dumb Muscle, though.
 * Cultured Badass: Known to occasionally stop in the middle of battle to recite war poetry.
 * Elite Mook
 * Fake Ultimate Mook: In Halo 1, they were pushovers.
 * Giant Mook: Variable. Around eight feet when they hunch over to fight, but more if they stretch out to full height.
 * Luckily, My Shield Will Protect Me: They also use it as an melee weapon if you invade their personal space. A melee weapon which can send a Spartan flying several meters if it doesn't kill them.
 * Made of Iron: Those shields are made of the same metal the Covenant use to build warship hulls.
 * Meaningful Name: The UNSC's vehicles are are mostly named after animals (Warthog, Scorpion, Pelican, etc.) The Mgalekgolo are sent largely as anti-vehicle platforms, so they are hunting said animals
 * Punch Clock Villain: They only joined the Covenant because they lost the war against them and for its technology, and they don't have any real grudge against the humans.
 * Starfish Alien
 * Took a Level in Badass: From Fake Ultimate Mook to Boss in Mook Clothing; it seems the longer the series goes on, the stronger the hunters get.
 * Unstoppable Rage/Roaring Rampage of Revenge: Once one of them dies, the other one will get pissed, and if playing on a level higher than Easy, you're in big trouble.
 * Warrior Poet: According to Ghosts of Onyx, they've been known to pause mid-battle to recite war poetry.
 * The Worm That Walks: One of the few non-evil examples. They're colonies of the eel- or worm-like Lekgolo, with each colony having its own collective consciousness encompassing its component Lekgolo.
 * Worthy Opponent: With the Elites.

The Yanme'e (Drones or "Buggers")
(Turpis Rex )
 * Bee People
 * Fearless Fool: Word of God states that they're incapable of feeling fear.
 * Fragile Speedster: Very hard to hit, but only a few shots are needed to take one down.
 * Heavyworlders: Surprisingly; one theory is that they may have actually evolved on their twice-Earth-size planet's Mars-sized moon.
 * Hive Mind
 * Ludicrous Gibs: Will explode if headshot in Reach.
 * Shout-Out: Their nickname of "Buggers" is a reference to Ender's Game.
 * To Serve Man- In ODST, can be seen munching on human corpses.
 * Zerg Rush

The Huragok (Engineers)
(Facticius Indoles )
 * Actual Pacifist
 * Darker and Edgier: Engineers are not portrayed sympathetically in Reach.
 * The Engineer: Duh.
 * Gadgeteer Genius
 * Planet of Hats: All of them will mindlessly fiddle with anything broken. Or fixed.
 * Ridiculously Realistic Robots
 * Slave Mooks
 * Starfish Alien

Covenant Special Operations

 * Elites Are More Glamorous: Your first mission as a Sangheili puts you along these guys sent on a suicide mission.
 * Invisibility Cloak: One of the main divisions that specialize in this, the other being Stealth Elites and Brute Stalkers.

Honour Guard of the Covenant

 * Blade on a Stick: Only in cutscenes. In-game the use Plasma Rifles or Energy Swords.
 * Driven to Suicide: Some high ranking Honour Guardsman committed suicide after the Prophet's betrayal and learning the truth about the Halos.
 * Praetorian Guard

Heretics

 * Color-Coded for Your Convenience: Heretics wear brown and gold armour to destinguish themselves from their Covenant counterparts.
 * Disc One Final Boss: The Heretic Leader
 * Hero Antagonist: They're the main enemy for the first half of the Arbiter's campaign.
 * La Résistance: Broke of from the Covenant after finding the truth about the Halos.
 * Took a Level in Badass: Heretic Grunts do not retreat when an Elite dies and are more efficient with their weapons.
 * What Could Have Been: Originally were only supposed to consist of Hunters.

The Flood
(Inferi Redivivus )
 * Arch Enemy: The Forerunners and the Humans. The Covenant is only seen as Cannon Fodder by them, but the Elites would be counted by them as well.
 * Blue and Orange Morality: Gravemind doesn't seem too clear on why people mind being consumed and transformed into parasitized zombies.
 * Body Horror
 * Combat Tentacles
 * Eldritch Abomination
 * I Am Legion
 * Our Zombies Are Different
 * Precursor Killers
 * The Virus
 * Zombie Apocalypse: Have likely consumed at least one other galaxy already before ever setting foot in ours.
 * Zombie Apocalypse: Have likely consumed at least one other galaxy already before ever setting foot in ours.

The Forerunners

 * Crazy Prepared: They programed the Halos monitors to destroy anything that would threaten the Halos.
 * Humans Are Special: Seemed to have held this view. We learn in Primordium that
 * Neglectful Precursors:
 * Not So Different: It's subtle, but you begin to notice that, despite their hat, they are about as variable personality-wise as humans. They have some Complete Monsters, Proud Warrior Race Guys, Friends to All Living Things, etc.
 * Planet of Hats: Their hat would be hypocrisy and possession of massive superiority complexes. They subvert it more than other species on this page though.
 * Precursors: And they had precursors of their own, whom they called... "The Precursors".
 * Ragnarok Proofing: Their stuff, built over 100 millenia ago, is still in pretty good shape.
 * Sufficiently Advanced Alien
 * We Did What We Had To Do: When they activated the rings to finish the Flood. Lampshaded by Prophet of Truth on how they "wisely put aside their compassion; steeled themselfes for what needed to be done".
 * Turned Against Their Masters
 * Zombie Apocalypse: Fell victim to one of these.
 * Sufficiently Advanced Alien
 * We Did What We Had To Do: When they activated the rings to finish the Flood. Lampshaded by Prophet of Truth on how they "wisely put aside their compassion; steeled themselfes for what needed to be done".

The Precursors

 * Abusive Precursors:
 * Blue and Orange Morality:
 * Foreshadowing: Its title as the Timeless One is a clue that it's
 * Genocide Backfire:
 * Mind Screw:
 * Starfish Alien: And the real kicker?  Didact suspects that the Timeless One may have been   the appearance of the Precursors, but there's no evidence given for or against that idea.
 * Sufficiently Advanced Alien: To the Forerunner, which are pretty Sufficiently Advanced themselves.
 * There Can Be Only One:
 * Time Abyss:  Cryptum states that Precursor artifacts can be so old that tectonic shifts on planets unearth them after millions of years.
 * Tomato Surprise:
 * The Un-Reveal:
 * The Un-Reveal:
