Percy Jackson & the Olympians/Characters

Characters who appear in Percy Jackson and The Olympians.

Half-bloods
Sons and daughters of the Greek gods. They have heightened senses and combat skills that take the form of ADHD and their minds are hard-wired to read Ancient Greek, which gives them trouble reading English. Their skills and personalities are inherited from their divine parents (children of Aphrodite will be Love Freaks, children of Athena will be highly intelligent, and children of Apollo will be musically and/or medicinally inclined, as well as a good shot with a bow).
 * Attention Deficit Ooh Shiny: Thanks to their combat skills.
 * Badass Abnormal
 * The Beautiful Elite: Aphrodite's children.
 * Green Thumb: Demeter's children. Dionysus' twins, too - they work best with grapes, but since their dad isn't allowed to touch anything vaguely related to wine, they settle for strawberries instead (just them walking among the strawberry fields makes them of better quality already.)
 * Heroic Bastards
 * Improbable Aiming Skills: Apollo's sons and daughters are good at archery.
 * L Is for Dyslexia: Brains are hard-wired for Ancient Greek.
 * The Medics: Apollo's kids.
 * Neurodiversity Is Supernatural
 * Superpowerful Genetics / Lamarck Was Right: Powers relating to the domains of their divine parentage. For example, Demeter's children will have Green Thumbs, and Athena's children will be crazy-smart.
 * Supreme Chef: Demeter's children.
 * Teen Genius: Children of Athena and Hephaestus. Athena kids are wise and spend their time reading and researching, while Hephaestus kids are good with machinery.
 * Wrench Wench: Daughters of Hephaestus.
 * You Can't Fight Fate: A running theme of the series, justifiable given its origins. However, prophecies being what they are, it's terribly easy to misinterpret one's fate.

Perseus "Percy" Jackson
""Is he dangerous?" "Very, to his enemies.""

The son of Poseidon, god of the sea, and clear-sighted mortal Sally Jackson. The titular hero of the series, the books start in Percy's sixth grade year when he kills one of the Furies, masquerading as his pre-algebra teacher. Has a Cool Sword, Anaklusmos ("Riptide") and later becomes the third person in history to bear the.


 * Achilles' Heel:.
 * Amazon Admirer: Percy develops a crush on Annabeth Chase, daughter of Athena, within a few weeks of meeting her. Sure she can kick his ass, and does so on multiple occasions, but he would follow her into the Underworld if she needed his help. Before, Annabeth considers Percy a "Seaweed Brain" and crushes on Luke because Luke rescued her as a kid from mutant spiders. Then Luke betrays Camp Half-Blood and tries to murder Percy, after he survived a quest with Annabeth and Grover. It's implied that Annabeth started returning Percy's feelings when Luke betrayed her a second time by tricking her into holding up the sky, and then using her as a hostage against the party coming to rescue her and Artemis.
 * Animal Talk: Can talk to horses and other vaguely equine beasts and sea creatures, since his dad made them.
 * Author Avatar: Percy is pretty much an in-book avatar of Rick's son.
 * Badass Abnormal: Among demigods, after his in The Last Olympian.
 * Battle Couple: With Annabeth.
 * Book Dumb: He prefers to leave the deep thinking to Annabeth.
 * Chronic Hero Syndrome: Thanks in particular to his Fatal Flaw.
 * : A self-inflicted example.
 * Dangerous Sixteenth Birthday
 * Deadpan Snarker: Percy gets the award for being the most snarky in a World of Snark.
 * Don't Call Me "Sir"!: He doesn't like it various subjects of his father call him "lord." Blackjack, Percy's pegasus, still calls him "boss" though.
 * Embarrassing First Name
 * Fatal Flaw: Personal loyalty.
 * Informed Fatal Flaw: His big fat mouth and recklessness get him into far more trouble.
 * First-Person Smartass
 * Green-Eyed Monster: Of Luke's history with Annabeth.
 * Green Eyes
 * Heroes Prefer Swords: Percy's pretty terrible at anything besides the sword.
 * Human Mom, Nonhuman Dad
 * Indy Ploy: It'd be faster to count the number of times his plans didn't boil down to "I'll figure something out, in the meantime, try not to get killed."
 * Kissing Cousins: Although it's explained that gods don't have DNA, so there's nothing wrong with people from different cabins dating one another.
 * Leeroy Jenkins
 * Locked Out of the Loop: Chiron and Annabeth never seem to tell him anything.
 * Making a Splash
 * Momma's Boy
 * Meaningful Name: Named after the only Greek hero to actually get a Happy Ending. Also helps slay Medusa and hangs out with a pegasus.
 * And Medusa's hacked off head is involved with getting rid of his mother's husband, a "suitor".
 * Nice Guy
 * Olympic Swimmer: Don't try to deny it.
 * Only Known By His Nickname: Virtually no one calls him Perseus, except for maybe the demon cheerleaders. Not even the big bad does. This is pretty much the reason he can tell monsters from normal people. They are the only ones to say "Perseus" when talking to him.
 * Showy Invincible Hero: Became this in the fifth book.
 * Soft Water / Super Not-Drowning Skills: Not only can Percy always take a dive into water, from any height, to escape a bad situation (admit it, that's a handy thing to know), being submerged in water (more accurately, touching water in general, but it's strongest when he's submerged) heals and freshens him up, even to the point of detoxing any poison he's suffering from,; he doesn't even get wet unless he wants to. He can even use a lighter underwater. Being the son of the sea god has its perks.
 * Sweet Tooth: His favorite food is "anything blue and sweet", understandable, since his mom used to work at a candy store and brought home lots of free samples.
 * Undying Loyalty: His Fatal Flaw is said to be his loyalty to his friends.
 * "Well Done, Son" Guy - He's kind of a sucker for his dad's good opinion.
 * Will They Or Won't They - With Annabeth. They Do at the end of The Last Olympian. Even their fellow campers thought it was about time already.
 * Will They Or Won't They - With Annabeth. They Do at the end of The Last Olympian. Even their fellow campers thought it was about time already.

Annabeth Chase
""Athena always has a plan.""

Heroine of the series and the resident brainiac, Annabeth is the literal brainchild of Athena and military historian Frederick Chase (kids of Athena are just special that way). Her pastimes include architecture, Ancient Greek, killing monsters, and learning how to stab things. Annabeth ran away from home when she was seven and met up with Thalia and Luke; eventually they made their way to Camp Half-Blood, but lost Thalia in the process.

 * Dawson Casting: Sure, they aged her up to 16 for the movie, but that doesn't change the actress playing her from being 23.
 * Damsel in Distress: In The Titan's Curse. Not for very long, though.
 * Drop the Hammer: She used one as her first defense against monsters before she met Luke and Thalia.
 * Dumb Blonde: Inverted hard. Don't let her hear you insult her intelligence, either. She will gut you.
 * Expy: At first, of Hermione Granger. She's the smart girl of the trio, who despite having only recently entered the fantasy world knows a lot about it because of her research. Diverges later on, though.
 * Fatal Flaw: Hubris (Pride)
 * Informed Fatal Flaw: She claims that this is her flaw (and would doubtless like to believe it herself) but the flaw that gets her in far more trouble is complex abandonment issues that result in her irrational and reflexive mistrust in people who haven't done anything to deserve it (particularly Percy and her Father) and her exxagerated devotion to distant parental figures who treat her like crap (her mother and ).
 * First Girl Wins: If you exclude the bully at Yancy, Annabeth is the first named girl Percy meets.

 * The Beast Master: Pegasi, although we never see her use it in an actual fight.
 * Beta Couple: With Beckendorf.
 * : Ouch, Silena.
 * Faux Action Girl: For all the combat training they go through at Camp, Silena's not that great in a fight. Attributed to her being a daughter of Aphrodite.
 * Love Freak

Charles Beckendorf
Son of Hephaestus and constantly hanging out in the camp's metal forges. Can build bombs.

 * Human Mom, Nonhuman Dad
 * Meaningful Name: Lampshaded: their father is the god of thieves and their last name is Stoll.
 * The Tricksters

Thalia Grace
Daughter of Zeus and an eighties starlet with a poofy hairdo. Her birth broke the pact the Big Three had made after World War II to never have children again. She ran away from her alcoholic mother when she was younger, met up with Luke and eventually Annabeth, and made her way with them to Camp Half-Blood. There they were overwhelmed by monsters and Thalia stayed behind to hold them off, dying in the process. Zeus turned her body into a pine tree.


 * Abusive Parents: To say nothing of Zeus' abandonment, Thalia's mother was initially loving but then grew cold and distant, not to mention an alcoholic. The only reason Thalia didn't run away sooner was because of
 * Action Girl

 * Apocalypse Maiden: Narrowly averted.
 * The Archer: Is talented with a bow and arrow.

 * Midnight Blue Eyes
 * Blue Oni: To Percy.

 * Distaff Counterpart: To Percy, the main difference being that she has more self-confidence than Percy does.
 * Don't You Dare Pity Me!
 * Fan Girl: Of Punk rock and roll.
 * Fatal Flaw: Is said to be weak when offered power, like her father.
 * Human Mom, Nonhuman Dad
 * The Lancer
 * Also somewhat literal, considering her weapon of choice, aside from her standard bow and arrow, is a spear. That grows out from a can of Mace.
 * Posthumous Character:
 * Perky Goth: More of a goth-punk mix, however. She wears her hair short and choppy, dresses in dark colors, and likes Green Day a lot, but she's a really nice kid once she defrosts.
 * Plucky Girl
 * Put on a Bus:
 * Refusal of the Call:
 * Shock and Awe
 * The Snark Knight
 * Why Did It Have To Be Heights: Her acrophobia is said to be ironic, considering she's a daughter of the Lord of the Sky.

 * Big Sister Worship
 * Break the Cutie:

 * Fish Out of Temporal Water Averted
 * Fatal Flaw: Holding grudges.
 * Human Mom, Nonhuman Dad
 * Ineffectual Loner: Downplayed, as he could be pretty effectual while working alone as seen in both “The Battle Of The Labyrinth “and “The Last Olympian”
 * Ship Tease: He sure blushed around a lot in The Last Olympian, if that means anything...
 * Probably because she was a dryad and he was a preteen who was beginning to like girls.
 * Took a Level in Badass: Yes, the cute, excited little ten year old turns into one of the most badass characters in the series.
 * Troubled but Cute: At first he's just an annoying cute little bro, then . He stays cute.
 * The Unfavourite: Hades makes it blatantly obvious that he likes Bianca more than Nico.

Ethan Nakamura
Son of Nemesis, the goddess of revenge and balance, Ethan was one of the many residents of Cabin Eleven who went unclaimed or had no cabin of their own because their parents were minor gods.

 * Eye Scream: His mother took his eye part of the promise that he would change Olympus for the better.
 * Fallen Hero
 * Heel Face Revolving Door
 * Hoist by His Own Petard
 * Ineffectual Sympathetic Villain

A satyr and Percy's best friend, Grover is the Searcher sent to Yancy Academy to keep an eye on Percy. He leads Percy to Camp Half-Blood and joins him on each book's quest (except the second, where the object is to rescue him). His dream is to find the lost god of the wild, Pan.

 * Butt Monkey
 * Cowardly Lion: He's relatively small for his size, easily frightened, constantly complains about going into dangerous situations, but will literally go to hell and back for his friends.
 * Curtains Match the Window
 * Disability Superpower: Not really but he presents as this, using crutches when among Muggles to disguise his goat-legged gait.
 * Extreme Omni Goat
 * Expy: Of Ron Weasley. He's the goofy sidekick ostracized by the magical society (Grover because of his failures as a satyr, and Ron because he's poor) but nevertheless knows a lot about the magical society because he's grown up in it.
 * Friend to All Living Things: Comes with the territory.
 * Herald
 * Inept Mage: At first.
 * Interspecies Romance: Technically with a tree. In mythology, though, Juniper is a Dryad, and nymphs are often considered to be the female version of a satyr.
 * Magic Music
 * Nice Guy
 * Plucky Comic Relief
 * Race Lift
 * Took a Level in Badass: Goes from being the unquestionable Butt Monkey in The Lightning Thief to being a competent member of the good guys' team whose skill set complements the more action-oriented demigods.
 * Trademark Favorite Food: Enchiladas.
 * The Unfavourite: The Council of Cloven Elders has a very strong dislike for Grover out of all their satyrs, particularly after book four.

Chiron

 * Cool Teacher: Head of Camp Half-Blood.
 * Herald
 * Luke, I Am Your Father: Kronos is Chiron's dad, as with all the Olympians.
 * Mr. Exposition
 * Obfuscating Disability: We first see him as Mr. Brunner, Percy's wheelchair-bound Latin teacher. Turns out his wheelchair is merely a Hammerspace Hideaway for his horse legs.
 * Our Centaurs Are Different
 * Really Seven Hundred Years Old: The immortal trainer of heroes and all that. At least until it is deemed that his services are no longer needed.
 * Reasonable Authority Figure
 * Super Wheelchair: It's a Hammerspace Hideaway for his horse legs.

Tyson
Tyson is first introduced as a school friend of Percy's, but he is later revealed to be a Cyclops - one-eyed children of Poseidon, therefore making him Percy's half-brother.


 * The Ace: He sounds dumb sometimes, and he can be a bit of a crybaby, but he can do anything.
 * Adaptational Attractiveness
 * Berserk Button: Sort of. He never really seems to get angry (except at Polyphemus), but threatening harm to Percy or Annabeth is an excellent way to get him to squish you.
 * Cloudcuckoolander
 * Cyclops
 * The Engineer
 * Gentle Giant
 * Genius Ditz: He is apparently really good at Monopoly.
 * Trademark Favorite Food: Peanut butter.

Mrs. O'Leary
Quintus's dog.

 * Don't Call Me "Sir"!: He feels obliged to call Percy "boss", but Percy insists that he calls him by his real name.
 * Jive Turkey: Yo, boss!
 * Just Whistle: This is how Percy can summon him, as well as additional pegasi (Guido and Porkpie say hi) if needed.
 * Horseback Heroism: Much of the Final Battle is done with Percy riding him.
 * Pegasus: That's what he is.
 * Retcon: He was referred to by Percy as a girl in The Sea of Monsters, but in all books after that he's a guy.
 * Sapient Steed: He is, technically, a person, but he doesn't seem to mind serving as a mount.

Sally Jackson
Percy's mother.

Paul Blofis
""I hope that was a monster I just killed. I was a Shakespearian actor in college! Picked up a little swordplay!""
 * Action Dad: We, once again, refer you to Book 5, Chapter 18: My Parents Go Commando. Paul picks up a sword and promptly kills a dracaena with it. After which he says a memorable quote:

 * Happily Married: Marries Sally in Battle of the Labyrenth.
 * Punny Name: Percy initially calls him Paul Blowfish behind his back, but stops doing it after he gets to know him better.

Frederick Chase

Rachel Elizabeth Dare

 * Betty and Veronica: The Veronica to Annabeth's Betty.
 * The Chick
 * Did You Just Flip Off Cthulhu?: Famous for hitting the Big Bad in the face with a hairbrush.

 * I See Them, Too: Born with the Sight.
 * My Beloved Smother: At her best. No wonder Luke ran away.
 * My Beloved Smother: At her best. No wonder Luke ran away.
 * My Beloved Smother: At her best. No wonder Luke ran away.

Gabe Ugliano
Percy's abusive stepfather at the beginning of the series. He isn't the nicest of guys.


 * Evil Smells Bad
 * Jerkass: And how.
 * Meaningful Name / Punny Name: His last name should have plenty of hints as to his personality.
 * Meaningful Name / Punny Name: His last name should have plenty of hints as to his personality.

Gods
Tropes that apply to many of the gods:
 * Berserk Button: Don't sit in their chair.
 * Bunny Ears Lawyer: Many of the gods: Poseidon is one of the three most powerful gods in existence, and he walks around in a Hawaiian shirt and shorts; Dionysus likes playing Pac-Man and whines about only drinking pop; and Apollo is the god of medicine, drives the sun chariot as a Maserati Spyder, and lets fifteen-year-old girls take it for a spin.
 * Jerkass Gods: Most of the gods at one point or another, but especially Zeus and Ares. Even the most sympathetically portrayed have their moments.
 * Parental Abandonment: They're both victims of this and guilty of it.
 * Really Seven Hundred Years Old: Bordering on Time Abyss.

Aphrodite
The goddess of love and beauty. As one might expect, her role in an adventure story is pretty minimal.
 * Eternal Love: Even if the rest of Olympus were to crumble into dust, Aphrodite would live on, since she represents love and emotional attachment.
 * Hello, Nurse!
 * Love Freak
 * Obfuscating Stupidity: In The Lost Hero, Aphrodite shows an unexpectedly smart side to her in helping out her daughter,.
 * Trickster Mentor
 * Shipper on Deck: She even tells Percy that she'll screw with his relationship with Annabeth just for the hell of it.
 * World's Most Beautiful Woman: Arguably. Percy even describes her as looking like every girl he'd ever liked.

Ares
The god of war. As one might expect, he's petty and not that bright.
 * Badass Biker
 * Battle Aura: Emanates an aura that makes people violently angry.
 * Blood Knight
 * Dumb Muscle
 * One-Man Army: Can bless demigods and possibly mortals, temporarily turning them into one of these.

Artemis
The goddess of the moon, the hunt, and maidens. She is sworn as a perpetual maiden, and thus has no true children, but she does "adopt" maidens who foreswear men forever.
 * Animorphism: Possibly. When Artemis is fighting against Atlas she is seen taking different animal forms at great speed by Percy. He then admits that another possibility could be that is making him hallucinate and “see things”
 * The Archer
 * Badass in Distress: During The Titan's Curse.
 * Different As Night and Day / Sibling Yin-Yang: Her and Apollo.
 * Does Not Like Men: But she seems to be more mature about it than her hunters, as shown when she
 * Sibling Seniority Squabble: With Apollo.
 * Token Loli: Her preferred form, as it's the same age as many of her Hunters.

Apollo
The god of the sun, poetry, prophecy, and medicine, and Artemis's older twin brother (but don't bring that up). He speaks through the oracle of Delphi.

"Apollo: Green grass breaks through snow, Artemis pleads for my help, I am so cool."
 * The Archer
 * Big Brother Instinct: He has a bit of this for Artemis, considering how he defied Zeus's orders to give advice to Percy and his friends on how to save her.
 * Combat Medic
 * Cool Car: He likes the sun chariot in the form of a sports car. And he lets fifteen-year-old girls take it for a spin.
 * Different As Night and Day / Sibling Yin-Yang: With Artemis.
 * Hot God: This applies to most of the gods, but special emphasis is given to Apollo (and Aphrodite, but that's a given).
 * Real Men Wear Pink: Parodied. His being the god of poetry is Played for Laughs, with him spouting haikus at the best of times.


 * When Artemis points out that the last line is only four syllables, he changes it to: "I am so awesome."
 * The Power of the Sun
 * Sibling Seniority Squabble: With Artemis.

Athena
The goddess of wisdom. A perpetual maiden, her "children" are born from a quite literal meeting of minds between herself and a mortal.
 * Gray Eyes
 * Genius Bruiser: She is the goddess of both wisdom and battle strategy, and in classical mythology is one of the most powerful gods, perhaps only second or third to Zeus and Poseidon. Percy himself points out that Athena would be a worse enemy to have than even Dionysus or Ares, because if she planned to have you killed, then you would die. No matter what.
 * Athena is actually more powerful than Zeus, as her mother, Metis, was prophecied to always bear children more powerful than their sire. It's just, she also happens to be completely loyal to Zeus, regardless of the circumstances.
 * Lady of War
 * Overprotective Mom: Well, as "overprotective" as any of the absentee parent gods can get, anyway.

Dionysus
The god of wine, parties, and He's being "punished" by being assigned as the head of Camp Half-Blood for 100 years after chasing after an off-limits nymph, and is grouchy due to being put off the bottle and thus can't drink until his punishment is over. Has an extremely strong dislike of heroes. Known as "Mr. D" to the campers.


 * Big Damn Heroes: In The Titan's Curse, saving Percy, Thalia, Zoë, and Grover from Dr. Thorn and his soldiers.
 * Freudian Excuse: A non-villainous example. The reason he dislikes heroes is because his wife Ariadne was abandoned by the demigod Theseus.
 * Jerk with a Heart of Gold
 * My Name Is Not Durwood - Mr. D staunchly refuses to get any of the campers' names right. Just ask Peter Johnson Percy Jackson.
 * Mind Rape: His signature move.
 * Papa Wolf: Minor example, but he contacts Percy in a dream to make sure his son is safe.
 * Pet the Dog: Restoring Chris Rodriguez' sanity in The Battle of the Labyrinth.

Hades
The god of the underworld. Bitter and asocial, but not truly evil.


 * Animal Motif: He is described as been similar to a panther, lithe, graceful and dangerous
 * Authority Equals Asskicking: In “The Lighting Thief” upon Percy’s meeting with Hades he states that Hades, above Ares and Dionysus, radiated power and that he had an air of order and lordship. The Asskicking part is seen in his Big Damn Heroes moment in “The Last Olympian”
 * Big Damn Heroes: The end of The Last Olympian
 * Calling the Old Man Out: "And if there's one thing we can agree on, it's that you were a TERRIBLE father."
 * Dark Is Not Evil
 * Eerie Pale-Skinned Brunette
 * Everybody Hates Hades: Even though he didn't do anything to deserve it. Although this gets better in the end.
 * Not So Stoic: Around his family.
 * Orcus on His Throne: How Percy, Annabeth and Grover find him in “The Lighting Thief”
 * Papa Wolf: Hades, it seems, is willing to go to much further lengths to protect his children than his brothers, including visiting them in person. Plus, it's stated that lives in the Underworld with him.
 * Well,
 * Parental Favoritism: Hades makes it quite clear that he'd rather have alive instead of, though it's probably because of 's resemblance to their mother.
 * Simple Staff: Acording to Nico, Its His Weapon of Choice.
 * Simple Staff: Acording to Nico, Its His Weapon of Choice.

Hephaestus
The god of fire, blacksmiths, metallurgy, and technology.


 * Gadgeteer Genius
 * Genius Bruiser
 * The Engineer
 * Not Good with People

Hera
The goddess of women and marriage. She is quite possibly one of the three gods who have never had a demigod child (the other two being Artemis and Hestia).
 * Alpha Bitch
 * Bitch in Sheep's Clothing
 * Clingy Jealous Girl: To Zeus.
 * Dysfunctional Family: Tries to hide this.
 * Parental Favoritism: She flung Hephaestus off of Olympus for having the audacity to be born less than beautiful, and makes it painfully obvious that she dislikes those demigods born to already-married gods and goddesses.
 * Stepford Smiler
 * Yandere

Hermes
The god of messengers, travelers, and thieves. As such, he's always extremely busy.
 * Berserk Button: Never imply that he doesn’t care about his sons.
 * Obfuscating Stupidity: He knew all along.
 * Trickster Archetype: One of the oldest examples.

Hestia
The goddess of the hearth. She's often overlooked by the other characters, often quite literally.
 * Ascended Extra: From the original mythology.
 * Demoted to Extra: In the original mythology, and of course as part of her past in the books. She seems to have happily embraced the option, however.
 * Chekhov's Gunman:
 * Older Than They Look: Hestia in particular takes this trope out of all the gods, because she takes the form of a seven or eight-year old girl.

Poseidon
The god of the oceans, storms, earthquakes and horses. Poseidon is shown to take greater care of his children than other gods and as more mature than his brother Zeus.
 * Doting Parent: He is the best father in the world, compared to some of his fellow gods, especially Zeus and Hades
 * Father Neptune: The Greek equivalent of the Trope Namer. Especially apparent while fighting against Oceanus in The Last Olympian.
 * Immortal Immaturity: Averted. In ancient times he was very similar to Zeus in temperament. He would often hold grudges and be highly vindictive when things did not go his way. In the series he comes across as having matured to a degree where he is much more reasonable, at least compare to his brother.
 * Making a Splash
 * Prongs of Poseidon: The Trope Namer.

Zeus
Lord of Olympus and god of storms, justice, and oaths. The last two being ironic considering his actions throughout the series.
 * Bolt of Divine Retribution: Quite literally. His symbol of power is the "master bolt." The first lightning bolt and most powerful weapon in the series.
 * Jerkass: All the gods are this to a degree, but Zeus stands out compared to the others.
 * Karma Houdini: Despite breaking a sacred oath and pulling a ton of other crap Zeus is never held accountable for his actions. Instead his children often have to pay for his crimes and mistakes. Being the most powerful god around has its perks.
 * Immortal Immaturity: In ancient times, Zeus and Poseidon had almost interchangeable personalities. By modern day, Poseidon has matured to a degree, so he tends to be more reasonable. Zeus has not and still comes across as a pompous git who thinks he is perfect.
 * Pride: His defining characteristic and source of many of the problems throughout both series.
 * Shock and Awe

Kronos

 * Abusive Parents: Yes indeed.
 * And I Must Scream: He literally cannot die. The first time, he was chopped into bits and pitched into Tartarus. The second time,.
 * Big Bad
 * Big No
 * Chessmaster: One of the best, hands down. His plans are brilliant.
 * Eldritch Abomination
 * Eyes of Gold
 * Sadistic Choice: In the fifth book, Kronos frequently threatens to kill Percy's friends unless he surrenders to him.
 * Sealed Evil in a Can
 * Sinister Scythe
 * Time Master
 * You Have Failed Me...: Kronos decides to let Atlas rot due to his repeated failures.

Hyperion

 * The Dragon
 * Eyes of Gold
 * Foil / Evil Counterpart: Probably accidental, but he is pretty much this for Hades - one is a god and the other is a titan, Dark Is Not Evil vs Light Is Not Good, and both their names start with "H".
 * Kill It with Fire / Playing with Fire
 * Light Is Not Good
 * The Power of the Sun
 * Title Drop: Not of the book name, or even the series name, but the name of the publishing company.

Atlas

 * And I Must Scream: Has to hold up the sky.
 * : An infamously dramatic example.
 * The Brute
 * The Dragon
 * Hero-Killer:
 * Knight of Cerebus
 * Luke, I Am Your Father:

Krios

 * Butt Monkey: He thinks of himself this way
 * The Resenter: To the other Titans.

Titan of craftiness and forethought. Sided with the Olympians in the first war, but out of a desire for revenge on Zeus and thinking the Olympians cannot win switches sides to the Titans.
 * Affably Evil: If one can call him evil.
 * If My Calculations Are Correct: Implied that part of his foreknowledge is his ability to calculate probability to predict the most likely outcome.
 * Revenge Before Reason: One possible interpretation of his defection.
 * Satan Is Good: In a sense. He is referred to once as "the good Titan" for the aid he has given to mankind with fire and curiosity in defiance of Zeus.
