 * The Stoic
 * Took a Level In Badass: In season 6, he had a Crowning Moment of Awesome in almost every episode he was in, and fans actually began to like him, a far cry from the earlier seasons when he was a whiny, angsty Mary Sue and was surpassed only by Kate and Ana Lucia in fan resentment.

 * Action Girl

 * Anti-Hero: Type V --> Type III
 * Badass
 * Badass Bookworm: Loves reading almost as much as Ben.
 * Badass Long Hair

 * Abusive Parents: Hoo boy.
 * Agent Mulder
 * Back From the Dead: Subverted. We thought he'd been resurrected, but really it was just the Man in Black impersonating him.
 * Badass Grandpa
 * Bald of Awesome
 * Butt Monkey: Played so straight he's almost a deconstruction of the trope.
 * The Chew Toy
 * Cool Old Guy
 * Driven to Suicide: Ben "helps".
 * Freudian Excuse: A rare heroic example.
 * Hollywood Healing: Subverted. For a while we don't know that John was paralyzed, or that Rose had cancer. When it's revealed it was fixed upon coming to the Island, it becomes more and more apparent that it's the magical properties of the Island that fixed him.

 * Killed Off for Real
 * Knife Nut
 * Living Bodysuit: What poor Locke eventually ended up as.
 * The Messiah: Ultimately zigzagged. Although Jack is arguably the series' Messiah for stopping the Man in Black and restoring the Heart of the Island, Locke's death ultimately paves the way for Jack's Character Development in Seasons 5 and 6.

Hugo "Hurley" Reyes
""Okay, that thing in the woods... maybe it's a monster, maybe it's a pissed-off giraffe. I don't know. The fact that no one is even looking for us, yeah, that's weird. But I just go along with it. 'Cause I'm along for the ride. Good old fun-time Hurley! Well, guess what? Now I want some freaking answers!" Played By: Jorge Garcia; Caden Waidyatilleka (child) Centric Episodes: "Numbers", "Exodus, Part 3", "Everybody Hates Hugo", "Dave", "Tricia Tanaka Is Dead", "The Beginning of the End", "There's No Place Like Home, Parts 1 & 2", "The Lie", "The Incident, Part 2", "LA X", "Everybody Loves Hugo", "The End""


 * Anti-Hero: Type I
 * Big Good: At the end of the series, he is promoted to protector of the Island after the deaths of Jacob and Jack.
 * Big Fun
 * Cosmic Plaything: At least, that's what he thinks he is. And he sort of is, the same way all the Losties are.
 * Fat and Skinny: No matter who he's teamed with. Charlie, Sawyer, Locke, Miles.
 * Even more so in the episode Everybody Hates Hugo where his fast food coworker buddy is played by D.J. Qualls.
 * I See Dead People
 * Genre Savvy: But since the rest of the cast are mostly Genre Blind, it doesn't always help him.
 * Obfuscating Stupidity: Despite all the "Dudes" he often turns out to be the one with the solution to a problem. In fact he's often the one who realizes there's a problem in the first place.
 * Only Known by Their Nickname: To most people though Locke and Ben call him Hugo exclusively.
 * Only Sane Man: Regularly shown to be the only person on the Island who realises that keeping secrets from each other is what keeps causing them major problems and that if the Losties don't find some way to relax, they'll go insane. Hence, he built them a golf course.
 * As of the finale, he's likely the first Protector of the Island who can actually be said to be competent.
 * Plucky Comic Relief
 * Sad Clown
 * Took a Level In Badass: In the Season 3 finale, where he pulls a Big Damn Heroes with the Dharmavan. Takes another one in the Season 6 premiere.

 * The Brute: For his father in law.
 * Estrogen Brigade Bait
 * Fan Nickname ("Jinglish" for the butchered English he speaks until mid-S5)
 * Heroic Sacrifice: Stays on the submarine to die with his trapped wife rather than escape with the others.
 * Honor Before Reason: C'mon, he was going to kill Michael over a watch.
 * Jerk with a Heart of Gold: Big time!
 * It is, however, worth noting that the "Heart of Gold" part is slow in coming. Early on, Jin was the oppressive, angry husband of Sun and fans were not supposed to like him. The writers were setting up for a love triangle between Jin, Sun, and Michael. However, they changed their minds and decided to have Jin become a better husband, and Jin and Sun became the most faithful and longlasting pair on the Island.
 * Missing Mom: And he himself becomes a Disappeared Dad, but not by his own choice.
 * Never Found the Body: after the explosion of the ship, and his subsequent return.
 * Son of a Whore: His mother was a prostitute who dumped him on his father. His father isn't even sure if Jin is really his, but he raised him as his own, nonetheless.
 * Together in Death: With Sun.

""I lied.""

 * Borrowed Catchphrase: After saying she'd not harm Ben she knocks him out with an oar and is challenged about it.


 * Break the Cutie: You see it happen when.
 * But I Can't Be Pregnant: The Island sort of kills pregnant women, but that's not what she's worried about: she fears that she's pregnant with the child of the man who taught her English and with whom she had an affair just prior to leaving the Island. It's not.
 * Mafia Princess
 * Nice Job Breaking It, Hero: Jin's mother . , but in exchange Jin would work directly under him. The audience knows that it was as Paik's enforcer, which caused the near deterioration of her marriage.
 * Obfuscating Stupidity: For years she pretended that she had no idea about her status as a Mafia Princess and that her father was a Corrupt Corporate Executive. She only broke the facade so that her father would help Jin.
 * There's also season one when she pretended that she didn't speak English.
 * Together in Death: With Jin.
 * Took a Level In Badass: Once her flashforwards of being off the Island happened, it's clear losing Jin steeled her. So that she was no longer a downtrodden daughter she bought a controlling share in her father's company and told him now he will respect her.

Claire Littleton

 * Anti-Hero: Type V (in season 6), until her Heel Face Turn.
 * Ax Crazy: Quite literally in the final season.
 * Beware the Nice Ones: In season six.
 * Big Brother Instinct: The other survivors are very protective of her. Sawyer was so protective Miles even asked "What are you, her big brother?"

 * Dark Action Girl
 * Face Heel Turn: In season 6.
 * Go Mad From the Isolation

 * Aborted Arc: See below.
 * Back for the Finale: In the epilogue, Hurley and Ben bring him back to the Island, presumably to help his father move on.
 * Psychic Powers
 * Put on a Bus
 * Reality Warper: Walt shows signs of being one before being Put on a Bus. The polar bears seem to have been retconned away, but the dead bird was never explained.
 * Real Life Writes the Plot: The fact that a year was passing in real life but only a couple of months in screen each season meant that Walt had to be shipped off fairly quickly.
 * Tagalong Kid: The only kid who has ever been a main cast member.

Shannon Rutherford
""I've just been through a trauma here, okay?" Played By: Maggie Grace Centric Episodes: "Exodus, Part 1", "Abandoned""


 * A Death in the Limelight: Her centric episode had a lot of people pitying her, when finally her goals and motivations where put into the spotlight instead of Boone's and rendering her a truly sympathetic character. Then Ana-Lucia kills her.
 * Alpha Bitch: If the island was high school, there's no doubt Shannon would be the head of the popular clique.
 * Deadpan Snarker
 * Death by Sex: Or "Death By Sex with Sayid", since he has a pretty high rate of killing women.

 * Hidden Depths

 * Blue Eyes
 * Chronic Hero Syndrome
 * Deadpan Snarker: Has his moments, mostly when with Shannon.
 * The Determinator: No matter how often people (i.e Shannon) tell him not to bother, he still does his best to be a hero.
 * The Everyman: In spite of the fact that he runs his own company while in his 20s.
 * Fallen Princess: Averted. He takes to island survival and teamwork a lot easier than most.
 * The Lancer: To Locke, but more like his acolyte than anything.
 * Genre Savvy: Tying red shirts to the tree.
 * Honor Before Reason: Nearly drowns trying to save someone in the fifth episode despite not being a strong swimmer.
 * Jumped At the Call: From minute one, he's trying to be the hero... except that he's really bad at it, and everyone is already looking to Jack.
 * Like a Son to Me: Boone is like the son Locke never had, even informally calling him "Son" at one point.
 * Nice Guy: Probably the most likeable character on the show as he seems to spend most of his time helping others, asking what He can do to assist and generally trying to pull his weight. He was also spared the Character Derailment the writers hit Charlie with.
 * Non-Idle Rich
 * Not Blood Siblings: With Shannon
 * Flirty Stepsiblings
 * Spoiled Sweet
 * What Beautiful Eyes!: He's played by Ian Somerhalder. This is pretty much a given.

 * Aborted Arc
 * Anti-Hero: Type IV
 * The Atoner: Subverted. He seems to be a very clear-cut example of the trope, but he turns out to be utterly unrepentant, as his brother would have wound up in his position had he not made the choices he did.
 * Badass Preacher: Except he isn't really a priest, he just pretends to be.
 * Dies Wide Open
 * Dropped a Bridge on Him
 * Real Life Writes the Plot: This was because his actor wanted to leave the show.

Libby Smith
""I buried a lot of people, Hurley. So don't tell me that that wasn't real. And don't tell me you made me up. It's insulting." Played By: Cynthia Watros Centric Episodes: None"


 * The Shrink: Usually Type 3, but pulls into Type 2 at least once.
 * We Hardly Knew Ye: The only main character to never get a centric episode, though she had a brief flashback at the end of the Hurley centric "Dave". It took 4 years for the creators to reveal her surname!

Benjamin Linus
""How many times do I have to tell you, John? I always have a plan."

Played By: Michael Emerson, Sterling Beaumon (child)

Centric Episodes: "The Man Behind the Curtain", "The Shape of Things to Come", "Dead Is Dead", "Dr. Linus", "What They Died For", "The End""


 * Abusive Father
 * Affably Evil: He's very charming, polite and softspoken even when manipulating You and planning Your demise.
 * Anti-Villain / Anti-Hero: Type V --> Type IV
 * The Atoner: From the end of season 4 onwards, but made more explicit in season 6.
 * Badass Bookworm
 * Blatant Lies: He's so good at it, he convinces people he's regularly betrayed to eat from his hand.
 * Breakout Character: Michael Emerson's debut performance was so good the writers changed the script, they wanted him so badly.
 * Breakout Villain: Originally scheduled for a three-episode run, the writers evolved him into the main antagonist for most of the series.
 * Butt Monkey: It seems Michael Emerson's contract required him to get beat up and/or tied up at least twice a season.
 * The Chessmaster
 * Chronic Backstabbing Disorder
 * Consummate Liar
 * Crazy Prepared
 * Deadpan Snarker
 * Did You Just Punch Out Cthulhu?: In the season 5 finale.
 * Disc One Final Boss: In the early seasons he was portrayed as the Big Bad, but it became much more questionable with his enemy, Charles Widmore, entering the picture. Finally Ben wasrevealed to be a pawn of the REAL Big Bad, Man in Black/Smoke Monster the whole time. It's played pretty straight too, since Ben was defeated and captured in the season 3 finale, which was the halfway point of the series, in which it seemed everything was finally going to be okay for the Oceanic survivors, until the Your Princess Is in Another Castle twist ending, which lead to the second half of the series, which depicts Ben as slowly gearing toward a Heel Face Turn which he finally does in the final season.]]
 * The Dragon: He briefly pretends to be this to The Man in Black at the end of the series so he can avoid being killed by him as well as to get revenge on Charles Widmore. As soon as Man in Black went to the Heart of the Island without him, he immediately went back to siding with the survivors.
 * Enemy Mine: Pretty much this to the rest of the cast.
 * Freudian Excuse
 * From Nobody to Nightmare
 * Heel Face Turn: Done beautifully in a gradual build-up before finally being solidified in "Dr. Linus".
 * Karma Houdini: Some may see him as one of these. He survives the series and is forgiven by the characters despite the fact he committed several murders and put the survivors through hell. However he isn't a true example, as he constantly gets his ass kicked, loses everything he cared about, and he finally realizes what a monster he has been in his quest for power and decides to redeem himself of his actions, and in the afterlife he is shown to be a much better person and despite all of the forgiveness and redemption he still decides not to move on since he feels he hasn't earned it yet]] Lampshaded musically by the track "Karma Has No Price" that plays during his redemption scene.
 * Knight Templar Parent/Papa Wolf: Toward his adopted daughter, Alex, to the point of attempting to brainwash her boyfriend to prevent Alex from getting pregnant. His direct responsibility for her death is a major driver of his Atoner status in Season 4 and beyond.
 * The Lancer: Becomes Hurley's lieutenant on the Island at the end of the series.
 * Laser-Guided Karma: When he was the manipulative leader of the Others who killed and tormented people, he lost everything (his adopted daughter, his leadership, etc.). It worked both ways as well, since when Ben redeemed himself, things went a lot better for him and even safed his life.
 * Manipulative Bastard
 * Missing Mom
 * Morality Pet - He sucks as a father, and isn't exactly a saint in other aspects of his life, but his love for his adopted daughter is genuine.
 * More Than Mind Control - He's able to convince people who want him dead to do his bidding. Now THAT's skill.
 * The Napoleon: Even compared to Napoleon in the show on one occasion.
 * Non-Action Guy: He almost never uses a gun or engages in a fight which made his No-Holds-Barred Beatdown of Keamy all the more terrifying.
 * Number Two: To Hurley, post-finale.
 * Pet the Dog: The Season 6 episode "Dr. Linus" is one big, concentrated bottle of sympathetic moments.
 * Also seen in "The Man Behind The Curtain". Despite being responsible for The Purge, the only member of the Dharma Initiative Ben shows actual remorse for killing is Horace and respectfully closes his eyes.
 * Revenge by Proxy
 * Token Evil Teammate
 * Used to Be a Sweet Kid
 * Villain Protagonist: Late in the series.
 * Warrior Therapist: A villainous example; a master of More Than Mind Control and the Hannibal Lecture, but he has killed a Crazy Prepared ex-Marine with a telescoping baton and nearly choked a former cop to death in hand-to-hand combat.
 * Wouldn't Hurt a Child: How Alex became his adoptive daughter. He also decided.
 * Wicked Cultured
 * "Alright, I know I sound like a broken record, but how many times do we have to go over this? If you have the last cup of coffee, you remove the filter and throw it away. Fear not, I will make a fresh pot.."
 * Yandere: For Juliet, in Seasons 3 and 4. He even orchestrates Goodwin's death because he's his romantic rival. Then he shows Juliet the body and tells her "You're mine".

Dr. Juliet Burke
""It's very stressful being an Other, Jack. " Played By: Elizabeth Mitchell; Rylee Fansler (child) Centric Episodes: "A Tale of Two Cities", "Not in Portland", "One of Us", "The Other Woman", "The Incident, Part 2", "The End""

 * All Girls Want Bad Boys: With Edmund Burke, Goodwin and especially with Sawyer.
 * Back for the Finale: And how!
 * Badass Bookworm
 * Becoming the Mask
 * Beware the Nice Ones
 * Break the Cutie
 * Broken Bird
 * Capulet Counterpart: Uh, her name is Juliet. At first she shows romantic interest in Jack, but falls in love with Sawyer. Then dies.
 * A bit of an expansion: the Others and the Losties were usually opposing forces, similar to the Montagues and Capulets. Juliet was The Lancer to Ben until her Heel Face Turn.
 * Deadpan Snarker
 * Defrosting Ice Queen
 * The Dog Bites Back: Via cue cards -- "Ignore everything I'm saying." "Ben is a liar" "...And he's very dangerous." "But it has to look like an accident." "It's a very complicated surgery. No one would ever know."
 * Establishing Character Moment: One of her earliest episodes demonstrated that she doesn't play games. When Sawyer and Kate acted out of line, she aimed a gun at Kate's head. And Sawyer commented that she would have done it too without even batting a lash.
 * Extreme Doormat: Before joining the Others she worked for her ex-husband who walked all over her and flaunted his affair with his sexy new assistant. It took a Bus Crash to free her.
 * Heel Face Turn
 * Heroic Sacrifice
 * Hospital Hottie
 * Informed Attribute: Apparently she looks uncannily similar to Sarah, Jack's ex-wife. This actually came into play in the final season when she was Jack's Amicably Divorced ex in the flash-sideways, instead of Sarah.
 * Kuudere: Watch her normal cool, soft-spoken nature, and then watch her big smile when Sawyer brings her a flower.
 * The Medic
 * Not So Stoic
 * Took a Level In Badass: She used to be an Extreme Doormat. Check out the other tropes that describe her character and try to tell me that this doesn't apply.

 * As You Wish
 * Absentee Actor: While all characters have missed several episodes, Desmond is notable for missing enough in season 4, 5 and 6 that several recurring guest stars were in more episodes than him. Especially season 5, when he wasn't even in the finale (which usually every living character is in).

Ilana Verdansky
""What lies in the shadow of the statue?" Played By: Zuleikha Robinson Centric Episodes: "The Incident, Part 1""


 * Aborted Arc: Her entire storyline - Zuleikha Robinson says that Jacob was meant to be her character's actual father, but the only hint at this that wasn't cut is in "Dr Linus" (also the only episode of the season in which she plays a major role)
 * Action Girl
 * Badass Israeli
 * Bounty Hunter: Initially; recent events cast doubt on her fully telling the truth here.
 * Defrosting Ice Queen: But it never gets to truly happen.
 * Determinator
 * Dropped A Bridge On Her: Probably the most abrupt and unexpected one in the whole series- she literally blew up mid sentence, without any foreshadowing. According to Carlton Cuse, this was a quick way to remove her from the story once they decided to cut her arc.

 * Honey Trap
 * Killed Mid-Sentence
 * Mysterious Past
 * Promotion to Opening Titles: Though after promoting her, the writers decided they didn't have enough time to develop her - hence her minor role, lack of a centric episode, and abrupt death.

 * Affably Evil
 * All There in the Manual: He is The Nameless throughout the series; it practically goes out of its way to not give him a name. It was later revealed that the character's name was on Titus Welliver's chair. . Although this is likely non-canon, and just used by the production crew as short-hand.
 * Bad Boss: Towards the end of the series.

 * Expy: An ancient, incredibly powerful and manipulative demon described as the source of all evil with brilliant skills at Chessmastering, Xanatos gambits and who is capable of impersonating any dead person? Sounds like the First Evil.

 * Freudian Excuse: Like pretty much all of the other main characters.
 * Mommy Issues
 * Laser-Guided Karma: His manipulations, lies, and attempt to kill the survivors eventually resulted in them killing him
 * Manipulative Bastard
 * More Than Mind Control: The single person in the series who can effectively manipulate Ben;
 * Nice Job Fixing It, Villain: His murder of Sayid, Jin, and Sun gave the survivors the Heroic Resolve to kill him, rather than just simply leave him on the Island. This wouldn't be an issue for him had his plan to destroy the Island not made him mortal as well.

 * Shapeshifter Mode Lock: He doesn't appear to be able to shapeshift like he could before, stuck between either smoke cloud mode or fake!Locke.
