!!Clarke Griffin
[[quoteright:320:http://static.tvtropes.org/pmwiki/pub/images/61ce6b5b9e3ae16f28b7940790c41454.jpg]]
[[caption-width-right:320:"This isn't the Ark. Down here, every life matters."]]
-->'''Played by:''' Eliza Taylor, Ella Pitkin (young)

Clarke is the daughter of Abigail Griffin, a Councilwoman on the Ark. She is in lockup at the start of the series, but is sent to earth along with the rest of the 100.
----
* AllLovingHero: Clarke is instinctively driven to help and protect all of the 100, whether they're friend, foe, or total stranger. In "Earth Skills", she even stops Wells from killing Murphy, who had previously made a big show of what a sadistic jerk he is. While she ''is'' capable of hating people, she doesn't put that hatred above this instinct. However, as the series progresses, she becomes increasingly willing to torture, kill, and generally resort to violence. (Though a couple instances were in the defense of herself or someone else.)
** In "Murphy's Law", she takes this UpToEleven by working to save both Murphy and Charlotte from being executed, despite the fact that the former was hunting down a little girl for the purpose of killing her and the latter murdered Clarke's best friend.
* AntiHero: Increasingly becomes this as the series progresses; she resorts to more and more ruthless actions in order to ensure the safety of her people.
* {{Badass}}: She is very much a capable fighter able to kill others, which shows when it's necessary.
* BadassBisexual: [[spoiler:She's revealed to be bisexual after returning Lexa's kiss]].
* BeautyIsNeverTarnished: [[AvertedTrope Averted]]. After escaping Mount Weather, fleeing from Reapers in mine tunnels, being dragged through the forest by Anya, and getting into a fight with Anya in the middle of said forest, Clarke looks exactly as filthy as you would expect. The wounds she gets from this escape also last quite a while.
* BewareTheNiceOnes: She may be TheHeart and an AllLovingHero, but she is ''not'' someone to be messed with: When The Grounders refuse her offer of peace and later take her prisoner, she effortlessly kills one. Later, while preparing for the Grounder attack, she comes up with a plan to use the Dropship ignition fuel to roast the attacking Grounders.
* BiTheWay: She briefly returns [[spoiler:Lexa's]] kiss in "Bodyguard of Lies" but quickly breaks it off, not because she is uninterested but because she feels that she is simply not ready for a new relationship yet.
* BrokenBird: By "Contents Under Pressure". Her best friend was murdered right after she'd discovered her mother was responsible for the death of her father. She's had to resort to torture to get answers, had her heart broken by her love interest's dishonesty, and had her fundamental moral beliefs shaken. And by the end of "Blood Must Have Blood," she's so torn up about the consequences of her desire to keep her people safe that she [[spoiler: can't even enter Camp Jaha for fear of the guilt being too much to bear]].
* TheChainsOfCommanding: She has made a lot of hard decisions in securing an alliance between the clans and the sky people. [[spoiler:She even lets the meeting of the clan heads get blown up to ensure that they will be united against the ones who fired the missile, the Mountain Men. And ''then'' she and Bellamy decide to kill off all of Mount Weather in order to ensure the safety of their people.]] The guilt becomes too much in "Blood Must Have Blood" and she [[spoiler: takes off to parts unknown, leaving the care of Camp Jaha in Bellamy's hands.]]
-->'''Clarke''': I bear it so they don't have to.
* ChronicHeroSyndrome: Clarke is prone to trying to take care of everybody else first; her mother knows this and tries to warn her to take care of herself as well. Example: Even sick as a dog from the Grounder virus, her first instinct is still to make sure everyone else who is infected gets water.
* DaddysGirl: Clarke was very close to her father and is clearly still reeling from his execution even a year later. This is another reason her rift with her mother cuts so deeply.
* DeadpanSnarker: Sometimes, when the other characters are violating common sense:
-->'''Clarke:''' ''(having been asked how she can ignore the beautiful scenery)'' Well, it's simple. I wonder, why haven't we seen any animals? Maybe it's because there are none. Maybe we've already been exposed to enough radiation to kill us. [[SarcasmMode Sure is pretty, though.]]
* DyingDeclarationOfLove: [[spoiler: She tells Finn she loves him back before killing him]].
* FourTemperamentEnsemble: She is the Phlegmatic with Bellamy (Choleric), Octavia (Sanguine) and Raven (Melancholic).
* GreenEyedMonster: [[SubvertedTrope Subverted.]] While she isn't happy to find out that she's not the only girl in Finn's life, it isn't because she's jealous, but because she doesn't want to be involved in a love triangle. She promptly breaks off the budding romance between herself and Finn and works to smooth things over with Raven.
* {{Hallucinations}}: After [[spoiler:she kills Finn]] she starts having hallucinations out of guilt. Later turns out to be a HelpfulHallucination.
* TheHeart: What she wants to be to the 100. She's usually the first to point out that surviving is more important than their personal issues.
* HeroicBSOD:
** Even though it was her plan, the look on her face when she sees that the "torch the Grounders with Dropship engine" plan worked to perfection could best described as a mix between sadness and horror. She was probably hoping she wouldn't have to actually use it. However, she doesn't get to be in BSOD mode for long because the Mountain Men come and knock everyone out.
** She's in a very justified funk after [[spoiler: being forced to kill Finn]] in "Remember Me."
* HeroicSacrifice: She tries it in "Spacewalker", offering herself up to The Commander [[spoiler: instead of Finn]] and pointing out that she is responsible for many more Grounder deaths than he is. The Commander isn't having it though: Clarke torched those 300 Grounders, but they were soldiers and therefore accepted the risk of dying. [[spoiler: Finn killed innocent villagers]], so he's a murderer and the one The Commander wants dead.
* TheHeroine: The main character, and the one most determined to keep everyone alive.
* {{Hypocrite}}: Claims that murdering people is wrong but she kills a Grounder herself. Not only that, but she participates in the torture of Lincoln and then tries to justify it. Octavia rightfully tells her to shove it. A big part of her CharacterDevelopment is realizing this.
* IDidWhatIHadToDo: She justifies her more extreme actions as being necessary for the safety of her people.
* InSeriesNickname: "Princess" (referencing her privileged background) from some of the members of the 100, mostly Finn and Bellamy. It's affectionate for the former and mocking (at first) for the latter.
* InVinoVeritas: When Clarke gets drunk on a found bottle of whiskey, all her anger towards Wells really comes out.
* InformedAttribute: She's supposedly "privileged", but she was in a cell just like everyone else at the start of the series. She also doesn't claim any superiority over the rest of the 100 and wants to make sure that everyone survives, no matter who they are. This is a JustifiedTrope because Bellamy, who is actively trying to discredit Clarke's position, is the only one who actually calls her this.
* KickTheDog: She participates in Lincoln's torture. Admittedly she's doing it to save Finn's life but still.
* KillTheOnesYouLove: She's forced to kill [[spoiler: Finn, her LoveInterest]] in "Spacewalker."
* LastSecondChance: When the war is coming to a head, Clarke offers one to Anya, who has broken into the drop ship. She tells Anya that she can't win and seems prepared to accept a peaceful surrender. Anya attacks anyway and ends up held captive.
* TheLeader: While Bellamy ''tries'' to establish himself as this, Clarke is closer to the role in actual practice after being shunned for the first few episodes. Even Bellamy himself turns to her when he needs help rescuing Octavia in "His Sister's Keeper". The fact that Bellamy would resort to asking Clarke for help even knowing how pissed she is at him for costing over 300 Ark residents their lives speaks volumes about her importance in the group.
** The Grounders themselves acknowledge her as the leader of the Sky People, over Abby or the rest.
** Taken UpToEleven in "Coup de Grace" when she goes toe-to-toe with [[spoiler: Abby]] and flat-out declares that she might be the [[spoiler: Chancellor]], but Clarke is in charge.
* LoveIsAWeakness: Begins believing this at Lexa's behest in "Remember Me." Shown when she allows Bellamy to infiltrate Mount Weather when earlier in the episode she had been against it because it would endanger him. It's also the only thing that makes [[spoiler: the hallucinations of Finn stop]], as she had to let go of what she felt for him. However, she's since realized that this extreme viewpoint is wrong.
* TheMedic: Her mother is a doctor, so she has some knowledge of how to handle wounds. She's the primary source of healthcare among the 100 before the Ark comes down.
* MercyKill:
** Kills Atom in the third episode when she realizes that the wounds from the poison fog can't be treated with their supplies and that he's in great pain.
** Kills [[spoiler: Finn in "Spacewalker"]] rather than subject him to extreme Grounder punishment (then execution).
* MyGodWhatHaveIDone: This happens a lot to her
** Her MushroomSamba in "Day Trip" shows that she feels extremely guilty for her role in torturing Lincoln.
** She also gets a similar look on her face after torching the Grounders in "We Are Grounders, Part Two."
** Again when [[spoiler: she kills Finn]]
** [[spoiler: After she genocides the people of Mount Weather, including children and allies, causing her to exile herself from the camp]]
* NoOneGetsLeftBehind: Refuses to leave Jasper in Grounder hands after he's speared and captured in the first episode, despite Finn warning her that they might lose more people. Extends to everyone else: keeping everyone else safe is her top priority, and she convinces the adults to move against Mount Weather so they can save the 47 still trapped there.
* NotSoDifferent: Admits this of her and Abby in "Remember Me" after realizing that they would both go to extremes to keep everyone safe.
* OutDamnedSpot: At the opening of "Remember Me", she's seen [[spoiler: trying to clean Finn's blood off her hands, repeating "What did I do?"]]
* [[OnlySaneMan Only Sane Girl]]: In the Pilot, she's the first one to state that getting to Mount Weather, where a stockpile of supplies is waiting, is more important than arguing with each other or enjoying the planet. She is also one of only two people to point out why making the Ark think that they're dying is a stupid idea.
* PragmaticHero: Goes from AllLovingHero to this; Clarke begins to recognize the importance of ruthless actions in order to keep the 100 and later Camp Jaha alive.
* TheProtagonist: The principal viewpoint character.
* ProperlyParanoid: Was suspicious of Mount Weather from Day 1, despite very little evidence. Turns out, she was right to be worried.
* ReluctantWarrior: She tried her damnedest to avoid going to war with The Grounders and even insisted that there had to be another way to handle the situation that didn't involve the two sides slaughtering each other, but when war broke out anyway, she had no problem fighting to defend her people.
* SaveTheDayTurnAway: [[spoiler: After irradiating Mount Weather and saving the Sky People trapped inside]], Clarke is so guilty about everything she did to get to that point that [[spoiler: she leaves Camp Jaha without a specific destination in mind]] in order to cope with it.
* [[HeKnowsTooMuch She Knows Too Much]]: By proxy. She was put in a cell because she knew that her father discovered the flaw in the Ark.
* TakeMeInstead: Offers herself to the Commander to be killed in Finn's stead, because the massacre of 300 Grounder soldiers was her idea.
* TeethClenchedTeamwork:
** With Bellamy when she has to collaborate with him at first. As the series goes on they begin genuinely trusting each other.
** She chafes under her mother's leadership, and often goes behind her back.
** With Raven on occasion, oftentimes related to her relationship with Finn.
* ThouShaltNotKill: [[PlayingWithATrope Played with]]: She would really ''prefer'' not to kill anyone, but she will if circumstances force her to, [[spoiler: such as the MercyKill she performed on Atom in "Earth Kills" and the Grounder she took out in "The Calm".]] In season 2, her killing people is portrayed as a necessity despite the toll it takes on her.
* TragicKeepsake: Her father's watch, because it's the only thing she has left of him.
* TheUnfettered: She will do ''anything'' if it means keeping her people safe. By the end of "Blood Must Have Blood," in pursuit of this goal, she's burned hundreds of attacking Grounders alive at the dropship, [[spoiler: had a bomb dropped on Tondc, and killed all the Mountain Men by irradiating them]]. Her actions are discussed many times, and she always deems them necessary, although she showed clear hesitance before doing them and and might not very proud of them.
* YouAreNumberSix: [[SubvertedTrope Subverted.]] She is initially called "Prisoner 319", but this is quickly dropped when her real name is revealed.
* YoungAndInCharge: Though Abby is technically the Chancellor in Season 2, it's noted that Clarke is actually the one most people look up to and obey.
-->'''Abby:''' They (the Grounders) are being led by a child.\\
'''Kane:''' So are we.
* YouKilledMyFather: To Wells, who turned in her father for a crime, leading to his execution. She doesn't seek revenge for it, though, because she knows her mother is really responsible and was shifting the blame because it was easier than the truth.

[[folder: Wells Jaha]]
!!Wells Jaha
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/b943308edf018f3c1aa3d9bd331c3823.jpg]]
[[caption-width-right:350:"My dad didn't make the rules."]]

-->'''Played by:''' Eli Goree

Wells is the son of Chancellor Jaha, the leader of the Ark. Given some of the laws his father has enforced, he is not popular among the 100. He gets killed by one of the younger members because his father ordered her parents killed.
----
* AdaptationalHeroism: In the books, he did rat out Clarke's parents for treason. The show shifts the blame to Abby, who was SparedByTheAdaptation.
* BewareTheNiceOnes: He's a genuine NiceGuy, but he is also easily one of the 100's best fighters and almost killed Murphy in their knife fight. Not to that badass scene where he shot and killed 2-3 large panthers that were charging at the group at the time, with a few calculated shots.
* BlackDudeDiesFirst: While not the first of the 100 to die, his is the first death that genuinely shakes the main cast as well as the first major recurring character.
* ButtMonkey: Wells gets a lot of hate for his father's actions, even though he never did anything wrong. He's also earned the hatred of Clarke, even though he didn't actually turn in her father. He also gets killed by Charlotte.
* ChildhoodFriends: He and Clarke go way back.
* TheConscience: Was this before his death; he always advocated for the more moral choice and tried to make everyone get along.
* DeadpanSnarker: Sometimes. The best example is his response to a misspelled death threat against him.
* DeathByAdaptation: One of the viewpoint characters in the books, but is killed off in the third episode.
* LoveMartyr: He has rather obvious feelings for Clarke and even got himself arrested just so he could join the mission and try to make up for what he falsely claimed he did. Now he's trapped on Earth with a bunch of teens who have it out for him on account of his father's actions as Chancellor and to top it all off, Clarke ''still'' hates him.
** Taken UpToEleven in "Earth Kills": He cared so much for her that he lied about getting her father executed so that she'd hate him instead of her mother, who was actually responsible. And when she finally gets over hating him, he's murdered.
* OnlySaneMan: He quickly points out to the rest of the 100 that making the Ark think they're dead isn't a good idea, since it means that all of their doctors, engineers, and other professionals whose help they could use will be staying up in space.
* PromotedToLoveInterest: In the books he and Clarke used to be in a relationship. In the show he clearly likes her but is killed before anything can develop between them.
* SacrificialLamb: He's murdered by Charlotte in the third episode. The messy fallout of his death just proves to the 100 that they need law and order if they are to survive.
* SilentScapegoat: He knew Clarke's mother was the one who turned in her father, but he took the blame so that she wouldn't blame her mother. As soon as this is cleared up, he gets killed.
* SinsOfOurFathers: There are a lot of people who hate him because of Chancellor Jaha's decisions, even though he had nothing to do with those decisions. It gets him killed by one of the victims of his father's decisions.
* SmartPeoplePlayChess: His father's memento of him is a chess piece.
* ToBeLawfulOrGood: Wells' decision to go with the lawful side of the equation resulted in his turning in Clarke's father, a decision which Clarke hates him for. Or so he claimed. It was actually Clarke's mother who chose to uphold the law and turn in Clarke's father, and Wells wanted to spare Clarke that knowledge.
* YouMakeMeSic: Wells's response to getting a death threat carved into the wall of the drop ship?
--> '''Wells:''' You spelled 'die' wrong, geniuses.
* YouKilledMyFather: By proxy, nearly everyone (including Clarke, his oldest friend) has a grudge against Wells because Chancellor Jaha had their parents thrown out of an airlock. It gets him killed.

[[quoteright:348:http://static.tvtropes.org/pmwiki/pub/images/0171655d38b8105d4163931d14a2be11.jpg]]
[[caption-width-right:348:"Like you said, I'm a Grounder."]]

-->'''Played by:''' Marie Avgeropoulos, Olivia Steele-Falconer (young)

The first of the 100 to actually set foot on Earth. Before the series started, she had to live under the floor of her house for sixteen years because she is the second child in her family, which is a crime.
----
* ActionGirl: Firmly this by the season two finale; her training under Indra has made her a fierce and competent warrior.
* AffectionateNickname: Bellamy calls her "O."
* TheBait: Indra intends for her to be Reaper bait, but Octavia instead participates in the battle and earns the respect of the Grounders.
* BraidsOfAction: Incorporated into her hairstyle in season 2 to signal her becoming more and more immersed in Grounder warrior culture.
* CantGetAwayWithNuthin: In her backstory, it was revealed that Octavia was caught the ''first'' day Bellamy sneaked her out to be able to enjoy a masquerade ball.
* DarkAndTroubledPast: Being forced to live in hiding under the floor for sixteen years certainly qualifies.
* DeadpanSnarker: On occasion.
-->'''Octavia:''' ''(re: Clarke telling the group to stop gawking at the scenery and keep moving)'' Someone should slip ''her'' some Poison Sumac.[[note]]A calming drug[[/note]]
* FelonyMisdemeanor: While many of The 100 are guilty of relatively minor crimes, Octavia stands out because her "crime" is being the second-born child in her family, which is only a crime because of the need for strict population control. She was literally locked up for being born.
* FourTemperamentEnsemble: She fits the outgoing, cheerful Sanguine label with Bellamy (Choleric), Clarke (Phlegmatic) and Raven (Melancholic).
* GenkiGirl: At first, she's consistently cheery and optimistic, if snarky and unused to interacting with people. Loses this as time goes by and she dabbles more in the far more serious Grounder culture.
* TheImmune: One of the few people unaffected by the Grounder virus in "I Am Become Death."
* JerkWithAHeartOfGold: Her social skills are about what you would expect from someone who'd had limited human contact for the first sixteen years of her life, but she can be pretty nice when she tries. (Such as trying to make Monty feel better about not being able to join the mission to rescue Jasper.)
* MoralityPet:
** To Lincoln. He's willing to help the 100 (and save Finn's life) for her sake.
** To Bellamy. Octavia is the only person Bellamy cares about in the beginning, and most of his actions are intended for her safety.
* MsFanservice: Before the first episode is over she has stripped to her underwear and jumped into a river.
* NamedAfterSomebodyFamous: In-universe, Bellamy named her after [[http://en.wikipedia.org/wiki/Octavia_the_Younger Octavia]], younger sister to Emperor Augustus. [[note]] He had an older half-sister as well, also named Octavia. [[/note]] In a meta sense, she fits in with the main characters' ThemeNaming (after science fiction authors) by being named after Creator/OctaviaButler.
* {{Protectorate}}: Bellamy's calling in life is to look after her.
* SiblingYinYang: She's wild and impulsive, while her brother Bellamy is calm and calculating.
* SesquipedalianSmith: Octavia Blake.
* StarcrossedLovers: With Lincoln. She's from the Sky People, he's a Grounder. Their people are at war.
* TheStoic: Begins showing far less emotion in Season 2 after some Grounder exposure.
* TookALevelInBadass: After Indra takes her on as her second, she's taught proper Grounder fighting techniques.
* VisualDevelopment: She starts wearing BraidsOfAction and more Grounder-themed clothing in Season 2.
* WhatTheHellHero: She calls Clarke out on her more questionable actions in "Blood Must Have Blood."
--> '''Octavia''': You trusted Lexa. You had [[spoiler: a bomb dropped on Tondc.]] You let all those people...\\
'''Clarke''': I am doing the best I ''can.''\\
'''Octavia''': It's not good enough.

[[folder:Bellamy Blake]]
!!Bellamy Blake
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/6ab0807da7510a4fe05bbfd5e39f7ce8.jpg]]
[[caption-width-right:350:"Down here, weakness is death, fear is death."]]

-->'''Played by:''' Bob Morley, Spencer Drever (young)

Bellamy is Octavia's older brother. He is driven to protect her at all costs. He shot Chancellor Jaha in order to join her on the dropship. Fearing that he'll be executed for this if the population of the Ark ever comes to Earth, he tries to convince the 100 to remove their wristbands and make the Ark think they're dead.
----
* AdaptationalVillainy: Somewhat. In the books his primary concern was Octavia and didn't bother opposing Clarke's leadership. In the early episodes of the show, he works against her by promoting "whatever the hell we want." This does not apply later on as he starts to develop UndyingLoyalty towards her.
* AdviceBackfire: He tells a young girl who's having trouble sleeping to slay her demons when awake so they couldn't haunt her nightmares. She takes it far too literally.
* AffectionateNickname: "Bell" from Octavia.
* AlliterativeName: '''B'''ellamy '''B'''lake.
* AntiVillain: Of Type 3. He's not without a point in trying to break from the Ark but his methods are ruthless and a bit hypocritical as he's intent on replacing the Ark's control with his own.
* BigBrotherInstinct: This is Bellamy's one redeeming character trait before CharacterDevelopment -- he'll do anything to protect Octavia. He shot Chancellor Jaha just so he could go to Earth with Octavia. Played with a bit in "His Sister's Keeper" wherein he snaps that "[his] life ended when [Octavia] was born," but that was the anger speaking. Even after Octavia TookALevelInBadass, he still looks out for her -- seeing her in danger is enough for him to [[spoiler: irradiate Level 5 and kill off every Mountain Man.]]
* BreakTheHaughty: His MushroomSamba in "Day Trip," in which he's confronted by the ghosts of the people he indirectly killed, is the last in a series of events that challenge his viewpoints and leadership. By the next episode, he's far more humbled and willing to cooperate with Clarke.
* CharacterDevelopment: Goes from a self-serving anarchist to a dependable leader who genuinely cares about the 100.
* ControlFreak: At the start of the series, he tries to establish himself as dictator of the 100, especially where his sister's behaviour is concerned. He grows out of it though and usually defers to Clarke now.
* DeadpanSnarker: Has a knack for this.
--> '''Bellamy:''' You figured that impaling people on spears is code for "let's be friends"? Have you lost your damn mind?
* DressingAsTheEnemy: In "Coup de Grace" he kills a guard and takes his clothes in order to infiltrate Mount Weather.
* EasilyForgiven: In "Day Trip", Clarke forgives him for all of his previous actions without so much as a second thought, then helps him convince Jaha, the guy he ''shot'', to do the same (albeit in trade for valuable information). Of course, this is [[AllLovingHero Clarke]] we're talking about; Octavia is much less inclined to forgive and forget. He flips this on its head by offering it to Clarke in "Blood Must Have Blood" in a callback to their earlier conversation.
* EstablishingCharacterMoment: He's introduced about to open the door of the dropship and arguing with Clarke when she suggests it's a bad idea, but he immediately drops it after he sees his sister.
* EvenEvilHasStandards: He's willing to endanger both the 100 and their loved ones on the Ark just to save his own skin, but he won't let Murphy attack Wells unless it's a fair fight. He also refuses to hang Charlotte for the murder of Wells. Apparently, killing a little kid doesn't sit right with him.
* {{Foil}}:
** To Octavia; see SiblingYinYang below.
** To Clarke. Before they put aside their differences and begin working together, she was the daughter of a council member; he was a janitor. She believed in working with each other and with the Ark; while he was all about independence and letting the 100 do whatever they wanted. Additionally, Clarke rationalizes her more extreme actions [[IDidWhatIHadToDo because she believes them necessary for her goal]] while Bellamy is a more emotional decision maker, apparent in in "Blood Must Have Blood," where [[spoiler: Clarke pulls the lever that kills the Mountain Men because "[she] has to save them" and Bellamy joins her because Octavia was in danger.]]
* FourTemperamentEnsemble: He generally fits the charismatic, arrogant Choleric label with Clarke (Phlegmatic), Octavia (Sanguine) and Raven (Melancholic).
* FreudianExcuse: Having to constantly care for an illegal kid sister since he was six until they were found out and his mother was executed (and he lost his spot on the guard) did a number on him.
* HandsOnApproach: How he teaches Clarke how to shoot in "Day Trip."
* HeelRealization: In "Day Trip", he realizes that selfishly taking Raven's radio indirectly cause the death of 300 people on the Ark. He starts to become a better person after this.
* HeroicBSOD: Has a minor breakdown after learning that there were more guns and bullets in the base they found the original ones in, the lack of which was the reason so many of his people died. He believed if they'd searched harder then they wouldn't have lost so many people in the end.
* {{Hypocrite}}:
** Tries to appeal to the 100's rebellious instincts with calls for anarchy and defiance of the authority of the adults aboard the Ark, while simultaneously trying to position himself as a dictator. He thinks nothing of calling for {{Mercy Kill}}ing Jasper to stop his screams of agony but hesitates when faced with the prospect of doing so himself to Atom.
** He also talks about how Clarke would receive preferential treatment if the population of the Ark were to come to Earth, but he sees no problem with giving preferential treatment to people who take his side. (Example: Only sharing food with people who remove their wristbands).
** Would have let Murphy hang for Well's murder, but went out of his way to protect Charlotte [[spoiler: when he found out it was her that killed him, ]] from a lynch mob.
* JerkWithAHeartOfGold: He's a self-centered ManipulativeBastard, but he genuinely cares about Octavia and looks over the others. Later, thanks to CharacterDevelopment, he's loses much of the "jerk" and gains more of the "heart of gold".
* KnightTemplarBigBrother: He'll do anything to protect Octavia. ''Anything.'' Including shooting Chancellor Jaha and [[spoiler: deciding to irradiate hundreds of mountain men because seeing her in danger was the last straw]].
* TheMillstone: Bellamy shows what happens when a Millstone is charming enough to fool his allies into thinking that he ''isn't'' a hindrance. Needless to say this causes ''a lot'' of problems. Even worse, it's implied that he's being the Millstone on purpose. After his CharacterDevelopment, he becomes a genuine asset to the Sky People.
* MyGodWhatHaveIDone:
** In "Day Trip", his guilt over all the bad stuff he's done finally catches up with him, thanks in no small part to a serious MushroomSamba.
** He had a minor one when he saw the name of one of the children being the same as the man he killed [[spoiler: to infiltrate Mount Weather.]]
* MySisterIsOffLimits: He ties Atom to a tree and leaves him there overnight because he put the moves on Octavia.
* NumberTwo: Eventually becomes this for Clarke, despite previously butting heads with her. She does most of the leading while he backs her up and enforces her decisions.
* PetTheDog: Is kind to Charlotte and gives her advice on dealing with her nightmares which has unfortunate unintended consequences.
* PromotedToLoveInterest: Inverted. In the books, he enters a relationship with Clarke; in the show there are no explicit romantic feelings between the two of them despite clearly sharing a strong bond.
* TheResenter: To Octavia. He hates having to take care of her all the time and blames her for their mother being floated. [[SubvertedTrope He later admits he didn't mean that, though.]]
* SesquipedalianSmith: Bellamy Blake.
* ShirtlessScene: Gets a few. In the early episodes, this was his way of flaunting his disregard of the rules.
* SiblingYinYang: He's calm and calculating, while Octavia is wild and impulsive.
* TookALevelInKindness: After his HeelRealization and Jaha pardoning him of his crimes, he becomes a better person who genuinely cares about the others.
* UndyingLoyalty: Almost to a fault. Bellamy will do anything to protect those he considers responsible for. At first Octavia is the only person in this category, but it later extends to the rest of the 100.
** To Clarke in Season 2. In "Remember Me," he says "He would do anything for her. To protect her." It's implied he's not just talking about Lexa and Gustus.

[[caption-width-right:349:"I know it's a long shot, but this is our world now, and I think we can do better than the first time around."]]

-->'''Played by:''' Thomas [=McDonell=]

A delinquent who was locked up because he wasted three months worth of oxygen on an illegal spacewalk.
----
* CanonForeigner: Not present in the original novel.
* TheCharmer: Finn has "game"; he spends a large part of the pilot successfully flirting with Octavia and tucking a flower into her hair, but is also charming Clarke and trying to get her to laugh. And this is ''before'' we find out he actually has a longterm girlfriend.
* CharacterDevelopment: Originally started as a devil-may-care rebel who just seemed to go along for the ride. Has taken over Wells's place as the conscience of the group. Also his realization that his [[YourCheatingHeart sleeping with Clarke without telling her about Raven]] caused him to hurt two people he genuinely cared about. This has forced him to do some growing up. While not a leader like Bellamy, he does attempt to be a voice of reason despite necessity forcing the group to engage in more violent actions. [[spoiler:And after Clarke goes missing he starts getting more cold and ruthless in his actions.]]
* TheConscience: Grows into this over the course of season 1; he's the one who calls the rest out on their more extreme decisions and always aims for the peaceful, diplomatic solution. [[spoiler: Once Clarke goes missing in season 2, he slips into LoveMakesYouCrazy territory.]]
* CrappyHolidays: Hates Unity Day because it's based on a lie -- the 12 stations didn't magically get along, they only joined after the 13th station was blown out of the sky.
* CruelAndUnusualDeath: What Lincoln claims the Grounders will do to him -- first fire, then having his body parts cut off. If he isn't dead by sunrise, the Commander will finish him off herself. [[spoiler:Averted, but only because Clarke gives him a MercyKill]].
* EasilyForgiven: He's pardoned almost immediately by the rest of the camp for [[spoiler: massacring several innocent villagers on the grounds of it being an accident and that they were at war. Note that this almost causes a war between the two camps.]]
* EstablishingCharacterMoment: Unbuckles his safety harness and floats across the drop ship to banter with Clarke and Wells, quickly establishing him as a bit reckless but friendly and at least not antagonistic towards Wells for who his father is.
* HeroicSacrifice: [[spoiler: He surrenders himself to the Grounders, knowing full well they're going to kill him for his crimes, so that The Commander would go through with a truce.]]
* IDidWhatIHadToDo: His justification for shooting the grounder they capture and trying to leave one of their own to die because it would take time in their search of Clarke and the others.
* ItAmusedMe: His reason for wasting three months worth of precious oxygen on a spacewalk? "It was fun." [[spoiler:It wasn't him that went on the spacewalk, it was Raven. He did make all the arrangements though.]]
* LivingEmotionalCrutch: To Raven. She declares that he's all [she has], that she owes him her life, and that they're family. Some of her more extreme and ruthless actions are to protect him.
* LoveMakesYouCrazy: When he thought Clarke had been taken by the Grounders [[spoiler:he ended up burning down their food shed, rounding them up, holding them hostage in a pen, and gunning down 18 villagers.]]
* TheSocialExpert: Shown to be very good at reading people and knowing how to talk to them, and is the first person to realize Wells is lying about having got Clarke's father arrested.
* TakingTheHeat: As it turns out, Finn isn't actually guilty of going on the illegal spacewalk that got him locked up. [[spoiler: He helped Raven go on a spacewalk and then said he'd done it himself because Raven was eighteen and would have been executed.]]
* YourCheatingHeart: Just as he and Clarke are becoming a couple, she finds out Raven is his girlfriend back in the Ark. In the next episode, Raven finds out he slept with Clarke.
* WhatHaveIBecome: After [[spoiler:he kills a number of villagers]] he lapses into this while alone with Clarke.

-->'''Played by:''' Christopher Larkin

One of the 100. He's a technological genius. He and Jasper were arrested for stealing pharmaceuticals from the Ark.
----

* AdvertisedExtra: Larkin is part of the main cast but Monty gets no major storylines of his own.
* AmbiguouslyGay: Is the only person present not to have any reaction when Octavia strips in the Pilot (the others present are Finn, Jasper, and Clarke, all of whom have since been into other girls), and has yet to show any interest in women.
* AsianAndNerdy: He and Jasper are the resident nerdy guys, insofar as they are very intelligent (Monty is TheSmartGuy until Raven appears), dorky and getting female interest is considered an achievement.
* BreakTheCutie: Season 2 was hard on him. After risking his life multiple times for the sake of the 47, he eventually [[spoiler: helps Clarke and Bellamy kill off all the mountain men. This act clearly left a toll on him and leads to a fallout with Jasper.]]
* CanonForeigner: Not present in the original novel.
* TheConscience: The biggest instance is in the finale, when he asks Clarke one last time if she's sure she wants to [[spoiler: irradiate the entire Mount Weather compound, killing hundreds of innocent people.]]
* FourTemperamentEnsemble: He generally fits the thoughtful, intelligent Melancholic label with Jasper (Sanguine), Miller (Choleric) and Harper (Phlegmatic).
* AFriendInNeed: He's loyal, friendly and will do anything to help his friends.
* FreudianTrio: Monty (Ego), Jasper (Id), and Miller (Superego).
* HeterosexualLifePartners: He and Jasper are extremely close and talk about everything together. They were even arrested for the same petty crime.
* NiceGuy: There's really nothing to hate about Monty.
* OnlySaneMan: He and Miller initially are the only people besides Clarke to think something's up with Mt. Weather. Jasper and the others come around eventually.
* RedOniBlueOni: Blue to Jasper and later Miller's Red.
* TheSmartGuy: Shares it with Jasper and later Raven. He focuses on computer science and is also mentioned to know a lot about plants.
* TeenGenius: He's incredibly smart, and underage.
* ThoseTwoGuys: With Jasper. Jasper and Monty are rarely seen apart and if they are, it's due to extraneous circumstances.
* WhatWouldXDo: Asks himself and Jasper "What would Clarke do?" when faced with the prospect of leaving Mount Weather.

-->'''Played by:''' Devon Bostick

Monty's best friend. They were arrested together for stealing pharmaceuticals from The Ark.
----
* AcquiredSituationalNarcissism: "I Am Become Death": His [=PTSD=]-induced attack on the Grounder peace treaty makes him popular among the rest of the 100 and he lets it get to his head, alienating Monty.
* AlliterativeName: '''J'''asper '''J'''ordan.
* BerserkButton: People getting speared seem to trigger anger, likely because he suffers PTSD from being impaled himself.
* BreakTheCutie: Jasper's really put through the ringer in Season 2. He's quick to trust the Mountain Men before learning that [[spoiler: they plan to use the 47 as sources of bone marrow. He becomes the unofficial leader of the 47 and feels responsible every time one of them dies. He finds an ally in Maya, and they fall in love along the way -- but she dies of radiation in his arms, which he thinks could have been prevented had Bellamy and Clarke just given him one more minute.]] This alienates him from Clarke and Bellamy (both of whom he clearly looks up to) and leads to a fallout with Monty, his closest friend.
* CanonForeigner: Not present in the original novel.
* DoggedNiceGuy: Towards Octavia in season 1.
* EtTuBrute: He has one of these moments with Monty, Clarke and Bellamy after they [[spoiler: kill all the mountain citizens by exposing them to radiation, including Maya]]
* FourTemperamentEnsemble: He easily fits the cheery, easily manipulated Sanguine label with Monty (Melancholic), Miller (Choleric) and Harper (Phlegmatic).
* FreudianTrio: Jasper (Id), Monty (Ego) and Miller (Superego).
* GogglesDoNothing: He wears old military "sun, wind & dust" goggles on his forehead. No explanation is given, and he never puts them on. He's without them for the entirety of season 2 until the end.
* HeterosexualLifePartners: With Monty.
* HopelessSuitor: Octavia has chosen both Atom and then Lincoln over him.
* ILetGwenStacyDie: Played with in "Resurrection." He feels responsible when Fox is dragged away by the guards as he promised her everything would be okay.
* ImpaledWithExtremePrejudice: He catches a spear through his chest in the pilot, but he survives.
* ImprobableAimingSkills: Averted for dramatic effect. Although he's one of the best shooters, he misses the bomb in "I Am Become Death" several times, and everyone would have died if Monty hadn't shown up with an extra round of bullets.
* TheQuisling: In Season 2, he's the most eager to accept [[spoiler: Mount Weather as their new home and the Mountain Men as their people]] -- Monty and the others are a bit more skeptical. This is played with when he sees the Mountain Men [[spoiler: use Grounders as HumanResources. After this revelation, the highers-up see him as this and implore him to invite more of the 47 to "volunteer" their blood, but Jasper is actively working on an escape plan]].
* RedOniBlueOni: Red to Monty and later Miller's Blue.
* RescueRomance: Averted, to his disappointment. He and Octavia grow closer after he saves her from being eaten by a sea snake, but nothing comes of it.
* TheSmartGuy: Shares it with Monty and later Raven. He's the resident chemist.
* ThoseTwoGuys: With Monty.
* TookALevelInBadass: Was somewhat wimpy in Season 1. In Season 2, due to the situation, he's become more of a take-charge kind of guy, and willing to do anything to save his friends.

-->'''Played by:''' Lindsey Morgan

A teenage mechanic enlisted by Abigail to help repair an escape pod. Her boyfriend is one of the 100.
----
* TheAce: The youngest and brightest zero-G mechanic on the Ark in 52 years. She initially wasn't allowed to become one because of a minor heart problem, but Sinclair gave the go signal after seeing her phenomenal test scores.
* AlliterativeName: '''R'''aven '''R'''eyes.
* BigNo: Lets one out when [[spoiler: she sees Clarke kill Finn.]]
* BrokenAce: By "We Are Grounders, Part Two", Raven has already been [[spoiler: shot in the spine by Murphy and is losing blood while desperately trying to stay alive long enough to help save the remaining 100]]. She laments to Clarke at always having been best at and picked first for everything on the Arc, only to end up on the ground rejected by the person she loves and [[spoiler: unable to even feel her legs.]]
* CanonForeigner: Not present in the original novel.
* DeathOfAThousandCuts: [[spoiler:What she was nearly subjected to after Gustus frames her.]]
* DontYouDarePityMe: She really doesn't like it when people try to help her [[spoiler:after she gets crippled and has to walk with crutches.]]
* TheEngineer: Actually [[InsistentTerminology The Mechanic]] for the 100, though the distinction isn't important until she's reunited with the Ark people. She makes everything from walkie-talkies to makeshift bombs.
* FourTemperamentEnsemble: She fits the Melancholic label with Clarke (Phlegmatic), Octavia (Sanguine) and Bellamy (Choleric).
* FrameUp: She was framed for attempting to murder The Commander. [[spoiler:It turned out to be her Lieutenant, Gustus.]]
* GreenEyedMonster: Towards Clarke, since she knows that Clarke and Finn slept together. Clarke has since broken off the offending relationship and is trying to keep things peaceful between herself and Raven, but Raven is still pretty angry. Averted as season 1 goes on and she becomes part of Clarke's inner circle.
* ICantFeelMyLegs: Murphy shoots her in the spine in the season 1 finale. They get her to Abby in time, but she's lost feeling in one of her lower legs and has to walk around with a cane or brace. She's ''not'' happy about it, but begins to adjust.
* IOweYouMyLife: She already felt this in spades for Finn before his arrest, but "Spacewalker" shows that he took the fall for her illegal spacewalk so she wouldn't get floated. This is why she's so loyal to him.
* IdiotBall: Raven's plan to free Finn after he gives himself up to the Grounders by having [[spoiler: Clarke kill their Commander would only have resulted in their killing ''everybody''.]]
* KickTheDog: Participates in torturing Lincoln and tries to [[spoiler: sell Murphy up the river in Finn's place as the one behind the massacre]], both in an effort to try and save her boyfriend's life.
* NiceJobBreakingItHero:
** Wasting months' worth of oxygen on an illegal spacewalk likely contributed to the oxygen shortage, which was one of the reasons for the deployment of the 100 and the culling.
** The flares she crafted and shot with the intent of getting the ark's attention blazed an entire village of grounders.
* ParentalNeglect: Her mother was a drunk and did not take care of her.
* SexForSolace: She sleeps with Bellamy in order to get over Finn cheating on her. Later, she admits that it didn't really make her feel better.
* TeethClenchedTeamwork: With Clarke after she finds out she slept with Finn. By the first season finale, they've put it behind them...only to come back in full force in season 2 after [[spoiler: Clarke kills Finn]]. She lashes out at her more than once, but keeps her head straight about it because taking down Mount Weather is more important.
* TeenGenius: Isn't even out of her teens yet and is already considered one of the smartest mechanics the Ark has ever had.
* TheSmartGuy: Increasingly takes over this role from Monty and Jasper once she arrives on the ground, as the 100's lack of technology is a huge problem and it's what Raven's good at.
* WrenchWench: She's an attractive girl who's great with machines. According to Abigail, she's the youngest Zero-G mechanic on the Ark. When asked if she could make an escape pod ready to enter the atmosphere within nine days, she simply answered "Hell yes."

-->'''Played By:''' Richard Harmon

Bellamy's initial right hand thug before getting kicked out of the camp.
----
* AssholeVictim: Nearly gets hanged by a vigilante mob for a murder he didn't commit. We'd be a lot more sympathetic if he hadn't already tried to murder Wells and his would-be executioners didn't consist mostly of people he'd been abusing.
* TheBully: Just one example: When Connor, who's working on building the settlement's defensive wall asks him for water he refuses and when Bellamy tells him to give Connor some he pisses on him after Bellamy has left.
* ButtMonkey: Murphy eventually replaces Wells's ButtMonkey status after he died. He almost gets hanged by an angry mob, gets exiled, is implanted with a virus, and then gets captured again by the Grounders who torture him...again. He makes it back to camp, but the others clearly haven't forgiven him. [[AssholeVictim Although unlike Wells, he actually does deserve it]].
* CanonForeigner: Not present in the original novel.
* TheDragon: To Bellamy, at first, then he went beyond even [[EvenEvilHasStandards Bellamy's bounds]] and gets exiled.
* TheDogBitesBack: In "Murphy's Law", Murphy harasses a kid that needed water before he can continue working. Later the kid was among the others who demanded Murphy's execution. He even ties a gag around his mouth. [[spoiler:In "I Am Become Death", [[EvilIsPetty Murphy kills him, likely as payback]].]]
* EvenEvilHasStandards:
** [[spoiler:Even he's horrified when Finn shot nearly all the innocent Grounders in the village. He tried to stop him before and during the shooting. Clarke accused him of not trying hard enough, and for that [[JerkassHasAPoint Murphy tells her that Finn was looking for her]].]]
** Likewise when [[spoiler: Jaha throws their companion out of the boat to be eaten, so he and Murphy can live]], Murphy is horrified and disappointed.
%%EvilIsPetty
* TheExile: He is kicked out of the camp, on pain of death if he returns, for hunting down and trying to kill Charlotte. He's later welcomed back (kind of).
* FreudianExcuse: He had two loving parents. When he got sick, his dad tried to steal medicine (which wouldn't help) and got floated. His mom succumbed to alcoholism, until she got sick, and her dying words are accusing her son of murdering his dad.
* HeelFaceTurn: Subverted. After his return from exile he appears to be doing his best to fit in and help. Then he murders Connor, and later tried to kill Bellamy. Seems to be for real in Season 2, even though he has his rude moments he honestly does try and help everyone.
* HeelFaceDoorSlam: Clarke and Raven make sure he knows they haven't forgiven him.
* IntergenerationalFriendship: Forms one with Jaha, ''kind of'' -- the latter is pretty much losing his mind over the duration of their journey.
* {{Jerkass}}: To everyone and anyone, even Bellamy. This does result in him getting his ass kicked and being treated like dirt quite a bit and is what results in the group trying to hang him when they suspected that he killed Wells.
* JerkassHasAPoint: When Bellamy refused to hang Charlotte for murdering Wells, he correctly points out that they had no issue letting him be hanged for it and he wasn't even guilty.
* LastNameBasis: Everyone calls him Murphy.
* NeverMyFault: He doesn't seem to grasp why people would be more willing to hang him than Charlotte, regardless of his innocence in Wells' death. Once he returns to the camp, he is constantly mistrusted and reviled, and thinks he's the victim in all this. Suppose all that murdering, attempted murderering, torture, bullying and general being a dick should just be swept aside?
* ReformedButRejected: He's shaped up quite a bit by season 2, but the others still clearly don't trust him. This is part of the reason he's so willing to go with Jaha on his journey.
* {{Sadist}}: Holds a girls face to the fire while taking off her bracelet. He claims it's for realism's sake but he was clearly getting off on it.
* TookALevelInKindness: He's a lot more tolerable in Season 2.

-->'''Played by:''' Jarod Joseph

Miller was a thief on the Ark and became one of Bellamy's inner circle on the ground.
----
* AmbiguouslyGay: The only male out of the 100 other than Monty to not show any interest in women. In fact, the only person he's shown even the slightest bit of interest toward ''is'' Monty.
* {{Badass}}: He is one of the more capable members of the 100, and during the Grounders assault on the dropship he kept fighting even after taking a spear to his right shoulder. He even takes down Anya in one hit.
* BerserkButton: Messing with his dad doesn't sit well with him.
* TheBigGuy: Particularly for the 47 who are trapped in Mt. Weather. He is one of the biggest and most physically capable members of the group and puts his strength to good use when bashing a wall in with a sledgehammer to expose the communications lines.
* BrutalHonesty: Even if the other characters don't like it.
* TheCobblersChildrenHaveNoShoes: Discussed with Monty. His dad was chief guard, while he was jailed for petty thievery.
-->'''Miller:''' He sure loved having a thief for a kid.
* DeadpanSnarker: He has his moments.
--> '''Jasper''' ''(To Clarke):'' We're guests here, not prisoners. And what would you do with a guest who kept calling you a liar, and generally acted like an ungrateful ass?\\
'''Miller:''' Kick the ungrateful ass out.
* TheDragon: Steps into this after Murphy is exiled. Discussed with Bellamy and Clarke.
-->'''Clarke:''' You left Miller in charge of the Grounder. You must trust him.\\
'''Bellamy:''' You should keep him close. The others listen to him.
* GrumpyBear: Of the Mount Weather group.
* FourTemperamentEnsemble: He easily fits the Choleric label with Monty (Melancholic), Jasper (Sanguine) and Harper (Phlegmatic).
* FreudianTrio: Miller (Superego), Monty (Ego) and Jasper (Id).
* JerkWithAHeartOfGold: He can be a jackass, but his main focus is keeping his friends safe. He was also one of the people who volunteered to inform parents on the Ark if their child died on the ground.
* LastNameBasis: Most people just call him Miller.
* OnlySaneMan: He and Monty initially in Mt. Weather. Jasper and the others come around eventually.
* RedOniBlueOni: Blue to Jasper's Red. And Red to Monty's Blue.
* TheStoic: Hardly shows any emotion. He's smiled maybe twice on the show.
%%TallDarkAndHandsome
%%TallDarkAndSnarky
* TeethClenchedTeamwork: Initially with Maya in Mt. Weather. He did not trust her and thought she might be a spy. He's not particularly fond of Jasper either.

----
* MercyKill: After being horribly burn and blinded by the acid fog, Atom begs for death. After Bellamy can't go through with it, Clarke does.
* NiceGuy: Unlike most of the 100 who initially follow Bellamy, Atom is a pretty decent guy.
* TemporaryLoveInterest: To Octavia. He initially sees her as a brat and a terrible assignment, but they grow closer. It's cut short when he's {{Mercy Kill}}ed by Clarke.
* TokenGoodTeammate: Of Bellamy's followers, he's the only decent one.

!!Roma
-->'''Played by:''' Celia Reid

A member of the 100 who entered into a relationship with Bellamy.
----
* ImpaledWithExtremePrejudice: She is killed when a Grounder hurls a spear which impales her to a tree.
* SkewedPriorities: When Raven's drop pod is seen coming down, Roma hopes that the Arc is sending them shampoo instead of something actually useful for survival.
* TemporaryLoveInterest: For Bellamy. She was one of two girls seen sleeping in his tent, and he was the hardest hit by her death, noting that she had only gone looking for Octavia because of him.

* BadDreams: Frequently had nightmares of Jaha killing her parents.
* ChildrenAreInnocent: Zig-zagged. She murders Wells in cold blood but seems to have very little understanding of the consequences of what she has done.
* DrivenToSuicide: Eventually jumps off a cliff due to the guilt caused by her murder of Wells and the uproar this causes in the camp.
* MoralityPet: One of the few people Bellamy shows a softer side to early on; he gives her advice on moving past her trauma. It...doesn't quite work. Even after she admits to killing Wells, he still attempts to protect her.
* TroublingUnchildlikeBehavior: Saw murdering Wells as a legitimate way to get over her parents' deaths. She does eventually feel bad about it.

* BraidsOfAction: Wears her hair tied back into three braids, one in the middle and two along the side of her head.
* CowardlyLion: She is among the more nervous and frightened fighters in the 100, but has stepped up a couple of times despite her fears to help the others.
* GenderBlenderName: Monroe is a more common name for boys than girls.
* ThoseTwoGuys: With Sterling in season two, [[spoiler:until Sterling dies]].
* TookALevelInBadass: During the Grounders attack on the dropship, she ran away after running out of ammo instead of fighting, and it is later hinted that she and Sterling fled the battle when the Grounders began to overrun the camp, which is why they avoided being captured by Mt. Weather. She gets braver after psyching herself and Sterling up in order to rescue Bellamy and Finn from Tristan, and later provides covering fire by herself for the others while they rescue Mel.

* ButtMonkey: As if having ''Jasper'' of all people turn down her offer of sex and then later being regulated to watch duty in Mount Weather wasn't bad enough, she was the first member of the 47 taken by the Mountain Men to have bone marrow forcibly extracted from her, which leaves her in very bad shape.
* FourTemperamentEnsemble: She generally fits the Phlegmatic label with Jasper (Sanguine), Monty (Melancholic), and Miller (Choleric).

-->'''Played by:''' Isaiah Washington

The leader of The Ark and Wells' father.
----
* BaldBlackLeaderGuy: Well, not ''bald'', but he's still the leader of the Ark.
* BeardOfSorrow: Grows one after being captured in Season 2, hinting at his SanitySlippage.
* BrutalHonesty: Chancellor Jaha outright admits to the 100 that the reason they were chosen for this mission was that their crimes made them expendable.
* DeathSeeker: During the first season, his two criteria for solutions to the many problems of the Ark seem to be "Will it solve the problem?" and "Can I somehow justify dying while implementing it?".
* DesperatelyLookingForAPurposeInLife: He's gotten a little obsessive over the idea that he survived 'for a reason'. Searching for the City of Light is part of it, he thinks he was chosen to lead his people to salvation.
* TheDeterminator: Becomes one in Season 2, after some words of encouragement from an image of his son.
* EvilChancellor: [[SubvertedTrope Subverted.]] He seems like this and is viewed this way by some of the 100, but in actuality he is a ReasonableAuthorityFigure who tries his best to avoid needlessly executing people.
* GoingDownWithTheShip: In "We Are Grounders, Part Two" [[spoiler: he makes a HeroicSacrifice by staying behind to manually disengage the final Dropship from The Ark, even though this means he cannot go with them. Subverted as he manages to save himself through a HelpfulHallucination of his son and get down to the ground.]]
* MeaningfulName: [[spoiler: As pointed out by the AI he finds]], Thelonius means "lord or ruler" (as he's the leader of the Ark at the beginning).
* ReasonableAuthorityFigure: He saved Clarke's mother from being thrown out of the airlock because she is a good doctor and saved his life, even if the means she used were illegal.
* SanitySlippage: Goes through this post-"Spacewalker" on his quest to find [[spoiler: the City of Light,]] becoming less of TheGoodChancellor and more of a semi-religious fanatic.
* SillyRabbitIdealismIsForKids: Seems to have taken this up in Kane's stead near the mid-season finale. While he was more extreme in trying to push the members of Camp Jaha into fleeing, he did have a point in that relying on Clarke was pushing it because if she was wrong they were going to be eliminated and that sacrificing Finn would be the best alternative.
* SupportingLeader: Of the Ark in the first season.

[[caption-width-right:350:"I have faith too...in my daughter."]]
-->'''Played by:''' Paige Turco

Clarke's mother. She is a government official on the Ark, and a surgeon.
----
* AngerBornOfWorry: When Raven helps Clarke escape from camp she slaps her before she even realizes it.
* TheChainsOfCommanding: After becoming Chancellor she has to deal with the stress of trying to keep everyone alive, knowing that it could mean war with one wrong decision. [[spoiler:Worse, most of the Grounders see Clarke as the leader of their faction.]]
* TheHeart: Plays the role for the senior staff of the Ark. Continually trying to keep everyone alive. Essentially acts as the MoralCompass.
--> '''Abby:''' I choose to make sure we deserve to stay alive.
** When Clarke starts resorting to more ruthless actions, Abigail plays this to her as well:
-->'''Abby:''' Try to remember that we're the good guys.
* InSeriesNickname: Her colleagues call her "Abby."
* LastMinuteReprieve: In the Pilot, Abby is in the airlock and the security officer has his hand on the button to open the outer door when the Chancellor arrives to pardon her.
* TheMedic: Resident doctor on the Ark.
* ScrewTheRulesImDoingWhatsRight: She saves Chancellor Jaha even though it means breaking the law by using more than the allowed amount of medical supplies. It may have been to make up for getting her husband killed.
* SparedByTheAdaptation: In the book, Clarke's mother was executed alongside her husband.
* SupportingLeader: After taking on the Chancellor title after Kane.
* WideEyedIdealist: She firmly believes that Earth is safe to inhabit, even in the absence of any proof. [[JustifiedTrope Justified]], since she has a daughter down there and doesn't want to believe that she is dead.

Chancellor Jaha's second-in-command on The Ark. Unlike Jaha, he believes in rigidly enforcing the law.
----
* CanonForeigner: Not named in the original novel.
* MyGodWhatHaveIDone: When they make contact with Earth and learn it's survivable, he feels this as he looks over the memorial for the 320 people he sentenced to death. His greatest regret is that if he had just waited ''three'' more days it wouldn't have been necessary.
* NameOfCain: Subverted. Although Kane initially appears sketchy and power-hungry, he does genuinely have the best interests of the Ark at heart, and works towards them even if his methods aren't often the best.
* NeverGotToSayGoodbye: His last words to his mother were disdain and refusal to participate in a religious ritual that mattered to her.
* OohMeAccentsSlipping: Henry Ian Cusick doesn't quite pull off Kane's American accent.
* ReasonableAuthorityFigure: Becomes one by the end of Season 1 and in Season 2.
* RedHerring: Is made to look like a major antagonist and the one behind the assassination attempt on Jaha. He's not.
* RedemptionEqualsDeath: Averted, twice. Once when someone has to stay behind to launch the Ark, Kane volunteers, but Jaha gets there first. Secondly, when they are imprisoned by the Grounders, [[ItMakesSenseInContext Kane attempts to kill himself so that Jaha won't die.]] This trope is even discussed with Abigail.
--> '''Abigail:''' You're only Chancellor because Thelonius beat you to redemption.
* SheatheYourSword: He takes this approach when trying to make peace with the Grounders after imprisoning one of them. [[spoiler:It gets him tossed into their version of a prison.]]
* SillyRabbitIdealismIsForKids: He establishes his WellIntentionedExtremist credentials by callously responding to Callie's pleas that he spare her friend by telling her that friendship is a luxury they can't afford. [[spoiler:He goes on the other end in Season 2, wanting peace despite the risks later on.]]
* WellIntentionedExtremist: He claims that everything he does is to ensure mankind's survival, whether or not its nice.

A high-ranking engineer.
----
* TheEngineer: He was responsible for keeping the Ark together and running smoothly. After arriving on Earth, Sinclair oversees the construction of Camp Jaha and its defenses. He also brings equipment and men to help recovery operations in Tondc after [[spoiler:it is hit by a missile from Mount Weather]].
* OnlySaneMan: He is the only major leader on the Ark who stays out of the power struggles and simply tries to do his job.
* ReasonableAuthorityFigure: Easily the most reasonable and friendly leader on the Ark, and he even cleared Raven for spacewalks after she was initially denied permission due to a minor heart condition because he recognized her talents.

* BunnyEarsLawyer: According to Sinclair, he's goofy and likes to poke fun but comes up with brilliant ideas.
* TheEngineer: Works with the Ark's technology. Keeps this up when they land on the ground.
* ScrewTheRulesImDoingWhatsRight: In "Human Trials" he briefly shuts off the power to the electric fence around Camp Jaha so that Clarke, Bellamy, and Octavia could sneak out to find Finn and Murphy.
* SecondLove: He's heavily implied to have it bad for Raven, as shown when he specifically asks her to work with him on a radio beacon. He even designed a brace for her leg. They slowly grow closer in the latter half of season 2.

!!Diana Sydney
-->'''Played by:''' Kate Vernon

Ex-chancellor who talks her way into a council position.
----
* KarmicDeath: Extremely eager to get her people and some of the working class off the Ark, everyone else be damned. The ship then crashes into the ground and explodes due to its systems being jammed by the Mountain Men.
* TheManBehindTheMan: Diana was the one behind the head guard orchestrating Jaha's murder.
* ManipulativeBitch: She was a very charismatic politician who knew how to turn people over to her side. Too bad her "side" involved launching the Exodus ship and crippling the Ark.
* NeverFoundTheBody: She's killed when the Exodus ship explodes, and her body is never found.

!!Jake Griffin
-->'''Played by''': Chris Browning

Father to Clarke and husband to Abby, Jake was an engineer on the Ark. He discovered a flaw in the oxygen systems that eventually led to his execution.
----

* DisappearedDad: To Clarke, who loved him dearly. His death is the reason for her tense relationship with Wells, then with her mother.
* HeKnowsTooMuch: He was executed because someone ratted him out before he was going to reveal the truth about the life support systems, which would have caused mass panic.
* NiceGuy: From what we know of him, he was idealistic, honest, loyal and devoted to his family, and thought that everyone on the Ark should have a fair shot at life.

-->'''Played by:''' Ricky Whittle

A native of the surface who has been watching the 100. Currently exiled from his Clan for siding with them. He is the closet thing the 100 have to an ally on the planet.
----
* AloofAlly: Becomes this to the 100 after bonding with Octavia. He's gruff and terse and most of them avoid him, but he helps where he can.
* AnnoyingArrows: Been shot twice, once in the chest and the other time near the kidneys. Both times treats such wounds as trivial.
* TheAtoner: Shows deep regret for his actions [[spoiler: as a Reaper]] and volunteers to accompany Bellamy to Mount Weather in order to face it.
* {{Badass}}: He used himself as bait for the Reapers and managed to come out alive and unscathed.
* TheBait: Twice, once to lead the Reapers away from Finn and Clarke. The second time he and Finn were this to the Reapers leading them to the Grounder invasion force...
* BeardOfBarbarism[=/=]BeardOfEvil: upgrades his PermaStubble to this [[spoiler: after being turned into a Reaper. It becomes a short-lived BeardOfSorrow after Clarke and Abby detox him]].
* CategoryTraitor: His people consider him one after he helps out the 100.
* CombatMedic: Was the Grounders' healer originally. Shown to be able to hold himself in a fight as well.
* CulturalRebel: According to Indra in "Blood Must Have Blood, Part One", he always questioned his people's way of life. Helping the 100 made him more of an outcast.
* DefectingForLove: Octavia is the catalyst for his leaving his people.
* HeroicWillpower: Averted, then played straight later. [[spoiler: When trying to smuggle Bellamy into Mount Weather, he defects back to the Reapers when offered more [[FantasticDrug Red.]]]] In the second season finale, [[spoiler: he overcomes both this temptation and his fear of the tone generator in order to kill Cage.]]
* MrFanservice: Is the most ripped of the main cast and obviously the one that gets the most {{Shirtless Scene}}s.
* MyCountryRightOrWrong: Averted, originally aided the 100 due to Octavia, he has shown to assist multiple times due to the fact that he believes what his people are doing is wrong.
* TheQuietOne: He's noticeably less talkative than any other major character.
* TheStoic: After being captured by the 100, Bellamy tortures him. He never says a word, and only gives them the information they need after Octavia willingly poisons herself.
* StarCrossedLovers: Technically he and Octavia comes across us this. She was born in Space and lived under ground. He was born on Earth and is a Grounder. His people see her people as Invaders and her people see his as savages determined to wipe them out.
* TragicMonster: He gets tortured, reprogrammed, biologically modified and addicted to drugs by the head of Mount Weather's security. [[spoiler:Effectively turning him into a bestial Reaper agianst his will. He gets better.]]

[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/8ed466d10cc12f9d616e18e995f28e6f.jpg]]
-->'''Played by:''' Dichen Lachman

An authority figure for The Grounders. She meets with Clarke to discuss a peace treaty.
----
* ActionGirl: Possibly the most badass female Grounder on the show.
* BadassBoast: In a last desperate attempt to salvage the peace talks, Clarke warns Anya that once the Ark soldiers come to Earth, they'll wipe out The Grounders. Anya responds that they've survived much worse.
* BadassLongcoat: Seems to be a signature getup shared by her and Commander Lexa, her former second. It's distinctive enough to suggest that the untouchable Heda might have had [[HeroWorshipper some inspiration]] in her formal getup.
* CharacterDeath: [[spoiler:She gets shot by members of the Camp Jaha right after parting with Clarke after agreeing to try and work towards peace.]]
* DualWielding: She dual-wields two long blades in the first season finale.
* EnemyMine: She and Clarke have to work together to escape Mount Winter.
* TheLeader: Subverted. Her group's only part of a larger faction, although she does have the authority to call for a truce.
** DemotedToDragon: When Tristan shows up and reveals the Grounders Commander put him in charge, she steps down.
* {{Hypocrite}}: While her points about the flares burning down the forest and Lincoln's torture do make sense, her accusations against the 100 seem to overlook the fact the Grounders impaled, kidnapped, and tortured Jasper before leaving him as bait for exploring territory they had no idea belonged to the Grounders, or that Lincoln's torture was in response to him kidnapping Octavia, holding her against her will, and stabbing Fin with a poisoned knife that nearly killed him. She blames the 100 for starting the war, but it was her side who acted violently first and started the conflict.
* TheMentor: Was previously one to the current commander.
* OccupiersOutOfOurCountry: Or off our planet, in this case. To her, The 100 are hostile invaders and she doesn't trust their offer of peace, seeing it either as a trap or a cheap attempt to avoid the war that they started.
* ShaggyDogStory: She and Clarke fight tooth and nail to get out of Mount Weather before Clarke offers to broker a truce between their people. Anya agrees, and [[spoiler: is shot by Camp Jaha guards]].
* ShadowArchetype: At first glance, she comes off as a darker version of Clarke: She's in a position of authority among The Grounders and clearly values the lives of her people enough to at least show up to a PeaceConference, but she has a much harsher attitude than Clarke and seems much less inclined to believe that peace is actually possible. [[JustifiedTrope Justified]] in that Clarke was raised by loving parents who taught her to value others' lives, while Anya was raised an a hostile DeathWorld where aggression and territorial paranoia are the only things that keep you alive.
* UngratefulBitch: She knocks Clarke out and takes her back to her people as a prize, despite the fact that Clarke put her life on the line to rescue Anya.
* VillainHasAPoint: While an antagonist to the 100, she points out they are trespassers on their land, which lead to Jasper being impaled in the pilot. Also, Bellamy did lead an intruding party despite the clearly marked warning. For Anya, the two people the Grounders have killed for trepassing on their land amounts to nothing compared to the whole village burnt down by the 100's flares. Clarke's offer of making peace now or the rest of the Ark wipes the Grounders out later didn't impress Anya either.
* WhatTheHellHero: When she accuses The 100 of being invaders, Clarke counters that they didn't know that anyone else was alive on Earth. Anya responds that they knew The Grounders were there when they led a raiding party onto Grounder territory, captured and tortured Lincoln, and burned down a Grounder village with their flares. (Though this last one was an accident.)
* WorstAid: Anya removes a tracker planted in her skin by ''biting down on the section of skin and then ripping it out''. She doesn't screw around.

-->'''Played by:''' Alicia Debnam Carey

Leader of the Grounders.
----
* ActuallyThatsMyAssistant: Has her bodyguard Gustus pose as the Commander while she pretends to be a slave girl. Jaha and Kane are shocked when they find out that the girl who waited on them for two days was actually the Grounder leader.
* AsskickingEqualsAuthority: She ''earned'' her position, and it's made clear that if she was weak she'd be killed by her own men.
* BadassGay: She became [[AsskickingEqualsAuthority leader of twelve clans]] through sheer badassery, and has only been explicitly attracted to women.
* BadassLongcoat: Part of her usual commander getup, combined with a long red ScarfOfAsskicking that trails from her shoulder pad.
* BeneathTheMask: Despite her LoveIsAWeakness facade, she often shows a gentler, softer side.
* BornAgainImmortality: She states that when she dies, her spirit will choose the next Commander and be reborn.
* CommandingCoolness: The highest-ranking leader of the Grounders with a rank of "Commander."
* FacialMarkings: Like many of the Grounders, she wears heavy black eye makeup and also a gold wheel-like adornment on her brow, probably to signify her as leader.
* KnifeNut: Her usual weapon of choice, including a long machete-like blade and she's deadly with throwing dagger as well, putting it through the hand of one of her fellow Grounders after threatening Clarke.
* IDidWhatIHadToDo: Lots and lots of times, the two major ones being [[spoiler:letting the site of her war council be bombed because evacuating more people than herself and Clarke would have tipped off the Mountain Men that their communications were being intercepted]] and [[spoiler:abandoning the forces of Camp Jaha after having negotiated the release of the Grounder prisoners from the Mountain Men.]]
* IronLady: She's renowned even by other Grounders for her ruthlessness
* LadyOfWar: She's her people's leader, is always [[TheStoic calm and composed]], and, by the standards of her Barbarian Tribe, she dresses and acts rather regally. She hasn't had too many fight scenes, but when she does fight, it's with a swift and graceful economy of movement.
* LoveInterestTraitor: Played with. [[spoiler: She admits her feelings for Clarke before kissing her, and then the next day on the battlefield, she invites Clarke to join her in the Grounder Capitol. Then during the battle, Lexa was offered a deal with the Mountain Men she couldn't turn down -- even though it meant betraying Clarke.]]
* LoveIsAWeakness: She began to believe this after her girlfriend was tortured and killed by an enemy clan who thought she knew Lexa's secrets.
-->'''Clarke''': So you just stopped caring? About everyone? ''(Lexa nods)'' I could never do that.\\
'''Lexa''': Then you put the people you care about in danger, and the pain will never go away.
* NeverBeHurtAgain: When her girlfriend was killed because of her power, Lexa decided that the best way to stop her (and anyone else close to her) affecting her was to close herself off to all feelings.
* ReasonableAuthorityFigure:
** It's mentioned that she's a visionary and, rather than simply charging and killing Camp Jaha, she gives them a chance to retreat and when they prove they can turn Reaper's back to normal they are willing to enter a truce so long as [[spoiler: Finn pays for the 18 he killed. When Clarke kills him and denies them the execution, she tells them that its done rather than let them have Clarke.]]
** She also is shown to acknowledge the distinction between killing in a war and outright murder: Clarke originally tries to offer herself in place of Finn, citing that she burned three-hundred Grounders alive. The Commander refuses the offer, saying that Finn is the one who is guilty.
** Concedes that assassinating her would in no way benefit the Sky People and turns on her loyal bodyguard when he confesses.
* SecretTestOfCharacter: Disguises herself as a slave girl attending to Jaha and Kane's cell in order to listen in on their discussion and judge if their desire for peace was genuine. They pass, and she gives the truce a chance.
* SergeantRock: She cannot show weakness to anyone, not even her men. But she does care for them dearly.
* TheStoic: Hardly shows any emotion. A notable exception is when she's forced to kill her bodyguard; she looks visibly shaken afterwards.
* SupportingLeader: The highest-ranking member of the grounders, she commands the military forces. She united a coalition of twelve different clans under her banner.
* TheWomanWearingTheQueenlyMask: Implied to be this; she notably became more closed-off and ruthless after Costia's death so she could better lead her people.
* YoungAndInCharge: She's obviously far younger than a lot of the Grounder warriors she commands.
-->'''Abby:''' (''on the Grounders'') They're led by a ''child''!

!!Tristan

-->'''Played by:''' Joseph Gatt

Another commanding figure among the Grounders, though with more authority than Anya and the ultimate goal of wiping out the 100.
----
* BigBad: Serves as this to the 100, considering he is the one leading the assault on them. Turns out to be a DiscOneFinalBoss.
* BoomHeadshot: Courtesy of [[spoiler: of Kane. He ends up meeting his end this way.]]
* DiscOneFinalBoss: The 100 thought that the Grounder invasion (headed by Tristan at the time) was the biggest threat to their life on Earth. They're wrong -- he's taken out easily at the start of season 2, and the Mountain Men are bigger fish to fry.
* {{Foil}}: If Anya is one to Clarke, then Tristan is one to Bellamy. Both are serious, ruthless leaders that wish for nothing short of their enemies' complete genocide. Differences again kick in when factoring in that Bellamy is a violently protective older brother that looks out for others, whereas Tristan seems to care very little for other people. Both also showed no problem with torturing enemies.
* TheStoic: Shows little to no actual emotion.
** NotSoStoic: However he tends to have an active fight or flight reaction when [[{{TheDreaded}} Reapers are involved.]] Then again there are [[NightmareFuel very good reasons for that.]]

* LadyOfWar: She has a certain fierce regality about her.
* MeaningfulName: Shares a name with [[http://en.wikipedia.org/wiki/Indra Indra]], the warrior leader of the Hindu gods.
* TheMentor: She decides to take Octavia as her second and train her in the art of combat.
* PetTheDog: In "Blood Must Have Blood" [[spoiler: she gives Lincoln the choice of whether or not to escape and help out the Sky People, knowing he cared deeply about Octavia, despite Lexa having just broken their alliance]] and showing notable distrust for the Sky People previously.
* TeethClenchedTeamwork: With the Sky People. After what happened with Finn and her village, this is understandable.

* ShadowArchetype: To Bellamy, who shares his unquestionable devotion to the people close to him and the willingness to go to extremes for them. In Gustus's case, he was ready to renew hostility between Camp Jaha and the Grounders all because the alliance would endanger Lexa. Bellamy shares this train of thought when he immediately pins Gustus as the perpetrator, and acknowleg admits later that it just "made sense" to him.

* MorallyAmbiguousDoctorate: Sees no problem with [[spoiler:keeping Grounders in cages and harvesting them for their blood]] or [[spoiler:killing an innocent girl with radiation]] for the sake of research.

!!Clarke Griffin
[[quoteright:320:http://static.tvtropes.org/pmwiki/pub/images/61ce6b5b9e3ae16f28b7940790c41454.jpg]]
[[caption-width-right:320:"This isn't the Ark. Down here, every life matters."]]
-->'''Played by:''' Eliza Taylor, Ella Pitkin (young)

Clarke is the daughter of Abigail Griffin, a Councilwoman on the Ark. She is in lockup at the start of the series, but is sent to earth along with the rest of the 100.
----
[[index]]
* AllLovingHero: Clarke is instinctively driven to help and protect all of the 100, whether they're friend, foe, or total stranger. In "Earth Skills", she even stops Wells from killing Murphy, who had previously made a big show of what a sadistic jerk he is. While she ''is'' capable of hating people, she doesn't put that hatred above this instinct. However, as the series progresses, she becomes increasingly willing to torture, kill, and generally resort to violence. (Though a couple instances were in the defense of herself or someone else.)
** In "Murphy's Law", she takes this UpToEleven by working to save both Murphy and Charlotte from being executed, despite the fact that the former was hunting down a little girl for the purpose of killing her and the latter murdered Clarke's best friend.
Characters/The100MainCharacters
* AntiHero: Increasingly becomes this as the series progresses; she resorts to more and more ruthless actions in order to ensure the safety of her people.
Characters/The100SkyPeople
* {{Badass}}: She is very much a capable fighter able to kill others, which shows when it's necessary.
Characters/The100Grounders
* BadassBisexual: [[spoiler:She's revealed to be bisexual after returning Lexa's kiss]].
* BeautyIsNeverTarnished: [[AvertedTrope Averted]]. After escaping Mount Weather, fleeing from Reapers in mine tunnels, being dragged through the forest by Anya, and getting into a fight with Anya in the middle of said forest, Clarke looks exactly as filthy as you would expect. The wounds she gets from this escape also last quite a while.
* BewareTheNiceOnes: She may be TheHeart and an AllLovingHero, but she is ''not'' someone to be messed with: When The Grounders refuse her offer of peace and later take her prisoner, she effortlessly kills one. Later, while preparing for the Grounder attack, she comes up with a plan to use the Dropship ignition fuel to roast the attacking Grounders.
* BiTheWay: She briefly returns [[spoiler:Lexa's]] kiss in "Bodyguard of Lies" but quickly breaks it off, not because she is uninterested but because she feels that she is simply not ready for a new relationship yet.
* BrokenBird: By "Contents Under Pressure". Her best friend was murdered right after she'd discovered her mother was responsible for the death of her father. She's had to resort to torture to get answers, had her heart broken by her love interest's dishonesty, and had her fundamental moral beliefs shaken. And by the end of "Blood Must Have Blood," she's so torn up about the consequences of her desire to keep her people safe that she [[spoiler: can't even enter Camp Jaha for fear of the guilt being too much to bear]].
* TheChainsOfCommanding: She has made a lot of hard decisions in securing an alliance between the clans and the sky people. [[spoiler:She even lets the meeting of the clan heads get blown up to ensure that they will be united against the ones who fired the missile, the Mountain Men. And ''then'' she and Bellamy decide to kill off all of Mount Weather in order to ensure the safety of their people.]] The guilt becomes too much in "Blood Must Have Blood" and she [[spoiler: takes off to parts unknown, leaving the care of Camp Jaha in Bellamy's hands.]]
-->'''Clarke''': I bear it so they don't have to.
* ChronicHeroSyndrome: Clarke is prone to trying to take care of everybody else first; her mother knows this and tries to warn her to take care of herself as well. Example: Even sick as a dog from the Grounder virus, her first instinct is still to make sure everyone else who is infected gets water.
* DaddysGirl: Clarke was very close to her father and is clearly still reeling from his execution even a year later. This is another reason her rift with her mother cuts so deeply.
* DeadpanSnarker: Sometimes, when the other characters are violating common sense:
-->'''Clarke:''' ''(having been asked how she can ignore the beautiful scenery)'' Well, it's simple. I wonder, why haven't we seen any animals? Maybe it's because there are none. Maybe we've already been exposed to enough radiation to kill us. [[SarcasmMode Sure is pretty, though.]]
* DyingDeclarationOfLove: [[spoiler: She tells Finn she loves him back before killing him]].
* FourTemperamentEnsemble: She is the Phlegmatic with Bellamy (Choleric), Octavia (Sanguine) and Raven (Melancholic).
* GreenEyedMonster: [[SubvertedTrope Subverted.]] While she isn't happy to find out that she's not the only girl in Finn's life, it isn't because she's jealous, but because she doesn't want to be involved in a love triangle. She promptly breaks off the budding romance between herself and Finn and works to smooth things over with Raven.
* {{Hallucinations}}: After [[spoiler:she kills Finn]] she starts having hallucinations out of guilt. Later turns out to be a HelpfulHallucination.
* TheHeart: What she wants to be to the 100. She's usually the first to point out that surviving is more important than their personal issues.
* HeroicBSOD:
** Even though it was her plan, the look on her face when she sees that the "torch the Grounders with Dropship engine" plan worked to perfection could best described as a mix between sadness and horror. She was probably hoping she wouldn't have to actually use it. However, she doesn't get to be in BSOD mode for long because the Mountain Men come and knock everyone out.
** She's in a very justified funk after [[spoiler: being forced to kill Finn]] in "Remember Me."
* HeroicSacrifice: She tries it in "Spacewalker", offering herself up to The Commander [[spoiler: instead of Finn]] and pointing out that she is responsible for many more Grounder deaths than he is. The Commander isn't having it though: Clarke torched those 300 Grounders, but they were soldiers and therefore accepted the risk of dying. [[spoiler: Finn killed innocent villagers]], so he's a murderer and the one The Commander wants dead.
* TheHeroine: The main character, and the one most determined to keep everyone alive.
* {{Hypocrite}}: Claims that murdering people is wrong but she kills a Grounder herself. Not only that, but she participates in the torture of Lincoln and then tries to justify it. Octavia rightfully tells her to shove it. A big part of her CharacterDevelopment is realizing this.
* IDidWhatIHadToDo: She justifies her more extreme actions as being necessary for the safety of her people.
* InSeriesNickname: "Princess" (referencing her privileged background) from some of the members of the 100, mostly Finn and Bellamy. It's affectionate for the former and mocking (at first) for the latter.
* InVinoVeritas: When Clarke gets drunk on a found bottle of whiskey, all her anger towards Wells really comes out.
* InformedAttribute: She's supposedly "privileged", but she was in a cell just like everyone else at the start of the series. She also doesn't claim any superiority over the rest of the 100 and wants to make sure that everyone survives, no matter who they are. This is a JustifiedTrope because Bellamy, who is actively trying to discredit Clarke's position, is the only one who actually calls her this.
* KickTheDog: She participates in Lincoln's torture. Admittedly she's doing it to save Finn's life but still.
* KillTheOnesYouLove: She's forced to kill [[spoiler: Finn, her LoveInterest]] in "Spacewalker."
* LastSecondChance: When the war is coming to a head, Clarke offers one to Anya, who has broken into the drop ship. She tells Anya that she can't win and seems prepared to accept a peaceful surrender. Anya attacks anyway and ends up held captive.
* TheLeader: While Bellamy ''tries'' to establish himself as this, Clarke is closer to the role in actual practice after being shunned for the first few episodes. Even Bellamy himself turns to her when he needs help rescuing Octavia in "His Sister's Keeper". The fact that Bellamy would resort to asking Clarke for help even knowing how pissed she is at him for costing over 300 Ark residents their lives speaks volumes about her importance in the group.
** The Grounders themselves acknowledge her as the leader of the Sky People, over Abby or the rest.
** Taken UpToEleven in "Coup de Grace" when she goes toe-to-toe with [[spoiler: Abby]] and flat-out declares that she might be the [[spoiler: Chancellor]], but Clarke is in charge.
* LoveIsAWeakness: Begins believing this at Lexa's behest in "Remember Me." Shown when she allows Bellamy to infiltrate Mount Weather when earlier in the episode she had been against it because it would endanger him. It's also the only thing that makes [[spoiler: the hallucinations of Finn stop]], as she had to let go of what she felt for him. However, she's since realized that this extreme viewpoint is wrong.
* TheMedic: Her mother is a doctor, so she has some knowledge of how to handle wounds. She's the primary source of healthcare among the 100 before the Ark comes down.
* MercyKill:
** Kills Atom in the third episode when she realizes that the wounds from the poison fog can't be treated with their supplies and that he's in great pain.
** Kills [[spoiler: Finn in "Spacewalker"]] rather than subject him to extreme Grounder punishment (then execution).
* MyGodWhatHaveIDone: This happens a lot to her
** Her MushroomSamba in "Day Trip" shows that she feels extremely guilty for her role in torturing Lincoln.
** She also gets a similar look on her face after torching the Grounders in "We Are Grounders, Part Two."
** Again when [[spoiler: she kills Finn]]
** [[spoiler: After she genocides the people of Mount Weather, including children and allies, causing her to exile herself from the camp]]
* NoOneGetsLeftBehind: Refuses to leave Jasper in Grounder hands after he's speared and captured in the first episode, despite Finn warning her that they might lose more people. Extends to everyone else: keeping everyone else safe is her top priority, and she convinces the adults to move against Mount Weather so they can save the 47 still trapped there.
* NotSoDifferent: Admits this of her and Abby in "Remember Me" after realizing that they would both go to extremes to keep everyone safe.
* OutDamnedSpot: At the opening of "Remember Me", she's seen [[spoiler: trying to clean Finn's blood off her hands, repeating "What did I do?"]]
* [[OnlySaneMan Only Sane Girl]]: In the Pilot, she's the first one to state that getting to Mount Weather, where a stockpile of supplies is waiting, is more important than arguing with each other or enjoying the planet. She is also one of only two people to point out why making the Ark think that they're dying is a stupid idea.
* PragmaticHero: Goes from AllLovingHero to this; Clarke begins to recognize the importance of ruthless actions in order to keep the 100 and later Camp Jaha alive.
* TheProtagonist: The principal viewpoint character.
* ProperlyParanoid: Was suspicious of Mount Weather from Day 1, despite very little evidence. Turns out, she was right to be worried.
* ReluctantWarrior: She tried her damnedest to avoid going to war with The Grounders and even insisted that there had to be another way to handle the situation that didn't involve the two sides slaughtering each other, but when war broke out anyway, she had no problem fighting to defend her people.
* SaveTheDayTurnAway: [[spoiler: After irradiating Mount Weather and saving the Sky People trapped inside]], Clarke is so guilty about everything she did to get to that point that [[spoiler: she leaves Camp Jaha without a specific destination in mind]] in order to cope with it.
* [[HeKnowsTooMuch She Knows Too Much]]: By proxy. She was put in a cell because she knew that her father discovered the flaw in the Ark.
* TakeMeInstead: Offers herself to the Commander to be killed in Finn's stead, because the massacre of 300 Grounder soldiers was her idea.
* TeethClenchedTeamwork:
** With Bellamy when she has to collaborate with him at first. As the series goes on they begin genuinely trusting each other.
** She chafes under her mother's leadership, and often goes behind her back.
** With Raven on occasion, oftentimes related to her relationship with Finn.
* ThouShaltNotKill: [[PlayingWithATrope Played with]]: She would really ''prefer'' not to kill anyone, but she will if circumstances force her to, [[spoiler: such as the MercyKill she performed on Atom in "Earth Kills" and the Grounder she took out in "The Calm".]] In season 2, her killing people is portrayed as a necessity despite the toll it takes on her.
* TragicKeepsake: Her father's watch, because it's the only thing she has left of him.
* TheUnfettered: She will do ''anything'' if it means keeping her people safe. By the end of "Blood Must Have Blood," in pursuit of this goal, she's burned hundreds of attacking Grounders alive at the dropship, [[spoiler: had a bomb dropped on Tondc, and killed all the Mountain Men by irradiating them]]. Her actions are discussed many times, and she always deems them necessary, although she showed clear hesitance before doing them and and might not very proud of them.
* YouAreNumberSix: [[SubvertedTrope Subverted.]] She is initially called "Prisoner 319", but this is quickly dropped when her real name is revealed.
* YoungAndInCharge: Though Abby is technically the Chancellor in Season 2, it's noted that Clarke is actually the one most people look up to and obey.
-->'''Abby:''' They (the Grounders) are being led by a child.\\
'''Kane:''' So are we.
* YouKilledMyFather: To Wells, who turned in her father for a crime, leading to his execution. She doesn't seek revenge for it, though, because she knows her mother is really responsible and was shifting the blame because it was easier than the truth.

[[caption-width-right:350:"My dad didn't make the rules."]]

-->'''Played by:''' Eli Goree

Wells is the son of Chancellor Jaha, the leader of the Ark. Given some of the laws his father has enforced, he is not popular among the 100. He gets killed by one of the younger members because his father ordered her parents killed.
----
* AdaptationalHeroism: In the books, he did rat out Clarke's parents for treason. The show shifts the blame to Abby, who was SparedByTheAdaptation.
* BewareTheNiceOnes: He's a genuine NiceGuy, but he is also easily one of the 100's best fighters and almost killed Murphy in their knife fight. Not to that badass scene where he shot and killed 2-3 large panthers that were charging at the group at the time, with a few calculated shots.
* BlackDudeDiesFirst: While not the first of the 100 to die, his is the first death that genuinely shakes the main cast as well as the first major recurring character.
* ButtMonkey: Wells gets a lot of hate for his father's actions, even though he never did anything wrong. He's also earned the hatred of Clarke, even though he didn't actually turn in her father. He also gets killed by Charlotte.
* ChildhoodFriends: He and Clarke go way back.
* TheConscience: Was this before his death; he always advocated for the more moral choice and tried to make everyone get along.
* DeadpanSnarker: Sometimes. The best example is his response to a misspelled death threat against him.
* DeathByAdaptation: One of the viewpoint characters in the books, but is killed off in the third episode.
* LoveMartyr: He has rather obvious feelings for Clarke and even got himself arrested just so he could join the mission and try to make up for what he falsely claimed he did. Now he's trapped on Earth with a bunch of teens who have it out for him on account of his father's actions as Chancellor and to top it all off, Clarke ''still'' hates him.
** Taken UpToEleven in "Earth Kills": He cared so much for her that he lied about getting her father executed so that she'd hate him instead of her mother, who was actually responsible. And when she finally gets over hating him, he's murdered.
* OnlySaneMan: He quickly points out to the rest of the 100 that making the Ark think they're dead isn't a good idea, since it means that all of their doctors, engineers, and other professionals whose help they could use will be staying up in space.
* PromotedToLoveInterest: In the books he and Clarke used to be in a relationship. In the show he clearly likes her but is killed before anything can develop between them.
* SacrificialLamb: He's murdered by Charlotte in the third episode. The messy fallout of his death just proves to the 100 that they need law and order if they are to survive.
* SilentScapegoat: He knew Clarke's mother was the one who turned in her father, but he took the blame so that she wouldn't blame her mother. As soon as this is cleared up, he gets killed.
* SinsOfOurFathers: There are a lot of people who hate him because of Chancellor Jaha's decisions, even though he had nothing to do with those decisions. It gets him killed by one of the victims of his father's decisions.
* SmartPeoplePlayChess: His father's memento of him is a chess piece.
* ToBeLawfulOrGood: Wells' decision to go with the lawful side of the equation resulted in his turning in Clarke's father, a decision which Clarke hates him for. Or so he claimed. It was actually Clarke's mother who chose to uphold the law and turn in Clarke's father, and Wells wanted to spare Clarke that knowledge.
* YouMakeMeSic: Wells's response to getting a death threat carved into the wall of the drop ship?
--> '''Wells:''' You spelled 'die' wrong, geniuses.
* YouKilledMyFather: By proxy, nearly everyone (including Clarke, his oldest friend) has a grudge against Wells because Chancellor Jaha had their parents thrown out of an airlock. It gets him killed.

[[caption-width-right:348:"Like you said, I'm a Grounder."]]

-->'''Played by:''' Marie Avgeropoulos, Olivia Steele-Falconer (young)

The first of the 100 to actually set foot on Earth. Before the series started, she had to live under the floor of her house for sixteen years because she is the second child in her family, which is a crime.
----
* ActionGirl: Firmly this by the season two finale; her training under Indra has made her a fierce and competent warrior.
* AffectionateNickname: Bellamy calls her "O."
* TheBait: Indra intends for her to be Reaper bait, but Octavia instead participates in the battle and earns the respect of the Grounders.
* BraidsOfAction: Incorporated into her hairstyle in season 2 to signal her becoming more and more immersed in Grounder warrior culture.
* CantGetAwayWithNuthin: In her backstory, it was revealed that Octavia was caught the ''first'' day Bellamy sneaked her out to be able to enjoy a masquerade ball.
* DarkAndTroubledPast: Being forced to live in hiding under the floor for sixteen years certainly qualifies.
* DeadpanSnarker: On occasion.
-->'''Octavia:''' ''(re: Clarke telling the group to stop gawking at the scenery and keep moving)'' Someone should slip ''her'' some Poison Sumac.[[note]]A calming drug[[/note]]
* FelonyMisdemeanor: While many of The 100 are guilty of relatively minor crimes, Octavia stands out because her "crime" is being the second-born child in her family, which is only a crime because of the need for strict population control. She was literally locked up for being born.
* FourTemperamentEnsemble: She fits the outgoing, cheerful Sanguine label with Bellamy (Choleric), Clarke (Phlegmatic) and Raven (Melancholic).
* GenkiGirl: At first, she's consistently cheery and optimistic, if snarky and unused to interacting with people. Loses this as time goes by and she dabbles more in the far more serious Grounder culture.
* TheImmune: One of the few people unaffected by the Grounder virus in "I Am Become Death."
* JerkWithAHeartOfGold: Her social skills are about what you would expect from someone who'd had limited human contact for the first sixteen years of her life, but she can be pretty nice when she tries. (Such as trying to make Monty feel better about not being able to join the mission to rescue Jasper.)
* MoralityPet:
** To Lincoln. He's willing to help the 100 (and save Finn's life) for her sake.
** To Bellamy. Octavia is the only person Bellamy cares about in the beginning, and most of his actions are intended for her safety.
* MsFanservice: Before the first episode is over she has stripped to her underwear and jumped into a river.
* NamedAfterSomebodyFamous: In-universe, Bellamy named her after [[http://en.wikipedia.org/wiki/Octavia_the_Younger Octavia]], younger sister to Emperor Augustus. [[note]] He had an older half-sister as well, also named Octavia.

[[caption-width-right:350:"Down here, weakness is death, fear is death."]]

-->'''Played by:''' Bob Morley, Spencer Drever (young)

Bellamy is Octavia's older brother. He is driven to protect her at all costs. He shot Chancellor Jaha in order to join her on the dropship. Fearing that he'll be executed for this if the population of the Ark ever comes to Earth, he tries to convince the 100 to remove their wristbands and make the Ark think they're dead.
----
* AdaptationalVillainy: Somewhat. In the books his primary concern was Octavia and didn't bother opposing Clarke's leadership. In the early episodes of the show, he works against her by promoting "whatever the hell we want." This does not apply later on as he starts to develop UndyingLoyalty towards her.
* AdviceBackfire: He tells a young girl who's having trouble sleeping to slay her demons when awake so they couldn't haunt her nightmares. She takes it far too literally.
* AffectionateNickname: "Bell" from Octavia.
* AlliterativeName: '''B'''ellamy '''B'''lake.
* AntiVillain: Of Type 3. He's not without a point in trying to break from the Ark but his methods are ruthless and a bit hypocritical as he's intent on replacing the Ark's control with his own.
* BigBrotherInstinct: This is Bellamy's one redeeming character trait before CharacterDevelopment -- he'll do anything to protect Octavia. He shot Chancellor Jaha just so he could go to Earth with Octavia. Played with a bit in "His Sister's Keeper" wherein he snaps that "[his] life ended when [Octavia] was born," but that was the anger speaking. Even after Octavia TookALevelInBadass, he still looks out for her -- seeing her in danger is enough for him to [[spoiler: irradiate Level 5 and kill off every Mountain Man.]]
* BreakTheHaughty: His MushroomSamba in "Day Trip," in which he's confronted by the ghosts of the people he indirectly killed, is the last in a series of events that challenge his viewpoints and leadership. By the next episode, he's far more humbled and willing to cooperate with Clarke.
* CharacterDevelopment: Goes from a self-serving anarchist to a dependable leader who genuinely cares about the 100.
* ControlFreak: At the start of the series, he tries to establish himself as dictator of the 100, especially where his sister's behaviour is concerned. He grows out of it though and usually defers to Clarke now.
* DeadpanSnarker: Has a knack for this.
--> '''Bellamy:''' You figured that impaling people on spears is code for "let's be friends"? Have you lost your damn mind?
* DressingAsTheEnemy: In "Coup de Grace" he kills a guard and takes his clothes in order to infiltrate Mount Weather.
* EasilyForgiven: In "Day Trip", Clarke forgives him for all of his previous actions without so much as a second thought, then helps him convince Jaha, the guy he ''shot'', to do the same (albeit in trade for valuable information). Of course, this is [[AllLovingHero Clarke]] we're talking about; Octavia is much less inclined to forgive and forget. He flips this on its head by offering it to Clarke in "Blood Must Have Blood" in a callback to their earlier conversation.
* EstablishingCharacterMoment: He's introduced about to open the door of the dropship and arguing with Clarke when she suggests it's a bad idea, but he immediately drops it after he sees his sister.
* EvenEvilHasStandards: He's willing to endanger both the 100 and their loved ones on the Ark just to save his own skin, but he won't let Murphy attack Wells unless it's a fair fight. He also refuses to hang Charlotte for the murder of Wells. Apparently, killing a little kid doesn't sit right with him.
* {{Foil}}:
** To Octavia; see SiblingYinYang below.
** To Clarke. Before they put aside their differences and begin working together, she was the daughter of a council member; he was a janitor. She believed in working with each other and with the Ark; while he was all about independence and letting the 100 do whatever they wanted. Additionally, Clarke rationalizes her more extreme actions [[IDidWhatIHadToDo because she believes them necessary for her goal]] while Bellamy is a more emotional decision maker, apparent in in "Blood Must Have Blood," where [[spoiler: Clarke pulls the lever that kills the Mountain Men because "[she] has to save them" and Bellamy joins her because Octavia was in danger.]]
* FourTemperamentEnsemble: He generally fits the charismatic, arrogant Choleric label with Clarke (Phlegmatic), Octavia (Sanguine) and Raven (Melancholic).
* FreudianExcuse: Having to constantly care for an illegal kid sister since he was six until they were found out and his mother was executed (and he lost his spot on the guard) did a number on him.
* HandsOnApproach: How he teaches Clarke how to shoot in "Day Trip."
* HeelRealization: In "Day Trip", he realizes that selfishly taking Raven's radio indirectly cause the death of 300 people on the Ark. He starts to become a better person after this.
* HeroicBSOD: Has a minor breakdown after learning that there were more guns and bullets in the base they found the original ones in, the lack of which was the reason so many of his people died. He believed if they'd searched harder then they wouldn't have lost so many people in the end.
* {{Hypocrite}}:
** Tries to appeal to the 100's rebellious instincts with calls for anarchy and defiance of the authority of the adults aboard the Ark, while simultaneously trying to position himself as a dictator. He thinks nothing of calling for {{Mercy Kill}}ing Jasper to stop his screams of agony but hesitates when faced with the prospect of doing so himself to Atom.
** He also talks about how Clarke would receive preferential treatment if the population of the Ark were to come to Earth, but he sees no problem with giving preferential treatment to people who take his side. (Example: Only sharing food with people who remove their wristbands).
** Would have let Murphy hang for Well's murder, but went out of his way to protect Charlotte [[spoiler: when he found out it was her that killed him, ]] from a lynch mob.
* JerkWithAHeartOfGold: He's a self-centered ManipulativeBastard, but he genuinely cares about Octavia and looks over the others. Later, thanks to CharacterDevelopment, he's loses much of the "jerk" and gains more of the "heart of gold".
* KnightTemplarBigBrother: He'll do anything to protect Octavia. ''Anything.'' Including shooting Chancellor Jaha and [[spoiler: deciding to irradiate hundreds of mountain men because seeing her in danger was the last straw]].
* TheMillstone: Bellamy shows what happens when a Millstone is charming enough to fool his allies into thinking that he ''isn't'' a hindrance. Needless to say this causes ''a lot'' of problems. Even worse, it's implied that he's being the Millstone on purpose. After his CharacterDevelopment, he becomes a genuine asset to the Sky People.
* MyGodWhatHaveIDone:
** In "Day Trip", his guilt over all the bad stuff he's done finally catches up with him, thanks in no small part to a serious MushroomSamba.
** He had a minor one when he saw the name of one of the children being the same as the man he killed [[spoiler: to infiltrate Mount Weather.]]
* MySisterIsOffLimits: He ties Atom to a tree and leaves him there overnight because he put the moves on Octavia.
* NumberTwo: Eventually becomes this for Clarke, despite previously butting heads with her. She does most of the leading while he backs her up and enforces her decisions.
* PetTheDog: Is kind to Charlotte and gives her advice on dealing with her nightmares which has unfortunate unintended consequences.
* PromotedToLoveInterest: Inverted. In the books, he enters a relationship with Clarke; in the show there are no explicit romantic feelings between the two of them despite clearly sharing a strong bond.
* TheResenter: To Octavia. He hates having to take care of her all the time and blames her for their mother being floated. [[SubvertedTrope He later admits he didn't mean that, though.]]
* SesquipedalianSmith: Bellamy Blake.
* ShirtlessScene: Gets a few. In the early episodes, this was his way of flaunting his disregard of the rules.
* SiblingYinYang: He's calm and calculating, while Octavia is wild and impulsive.
* TookALevelInKindness: After his HeelRealization and Jaha pardoning him of his crimes, he becomes a better person who genuinely cares about the others.
* UndyingLoyalty: Almost to a fault. Bellamy will do anything to protect those he considers responsible for. At first Octavia is the only person in this category, but it later extends to the rest of the 100.
** To Clarke in Season 2. In "Remember Me," he says "He would do anything for her. To protect her." It's implied he's not just talking about Lexa and Gustus.

[[caption-width-right:349:"I know it's a long shot, but this is our world now, and I think we can do better than the first time around."]]

-->'''Played by:''' Thomas [=McDonell=]

A delinquent who was locked up because he wasted three months worth of oxygen on an illegal spacewalk.
----
* CanonForeigner: Not present in the original novel.
* TheCharmer: Finn has "game"; he spends a large part of the pilot successfully flirting with Octavia and tucking a flower into her hair, but is also charming Clarke and trying to get her to laugh. And this is ''before'' we find out he actually has a longterm girlfriend.
* CharacterDevelopment: Originally started as a devil-may-care rebel who just seemed to go along for the ride. Has taken over Wells's place as the conscience of the group. Also his realization that his [[YourCheatingHeart sleeping with Clarke without telling her about Raven]] caused him to hurt two people he genuinely cared about. This has forced him to do some growing up. While not a leader like Bellamy, he does attempt to be a voice of reason despite necessity forcing the group to engage in more violent actions. [[spoiler:And after Clarke goes missing he starts getting more cold and ruthless in his actions.]]
* TheConscience: Grows into this over the course of season 1; he's the one who calls the rest out on their more extreme decisions and always aims for the peaceful, diplomatic solution. [[spoiler: Once Clarke goes missing in season 2, he slips into LoveMakesYouCrazy territory.]]
* CrappyHolidays: Hates Unity Day because it's based on a lie -- the 12 stations didn't magically get along, they only joined after the 13th station was blown out of the sky.
* CruelAndUnusualDeath: What Lincoln claims the Grounders will do to him -- first fire, then having his body parts cut off. If he isn't dead by sunrise, the Commander will finish him off herself. [[spoiler:Averted, but only because Clarke gives him a MercyKill]].
* EasilyForgiven: He's pardoned almost immediately by the rest of the camp for [[spoiler: massacring several innocent villagers on the grounds of it being an accident and that they were at war. Note that this almost causes a war between the two camps.]]
* EstablishingCharacterMoment: Unbuckles his safety harness and floats across the drop ship to banter with Clarke and Wells, quickly establishing him as a bit reckless but friendly and at least not antagonistic towards Wells for who his father is.
* HeroicSacrifice: [[spoiler: He surrenders himself to the Grounders, knowing full well they're going to kill him for his crimes, so that The Commander would go through with a truce.]]
* IDidWhatIHadToDo: His justification for shooting the grounder they capture and trying to leave one of their own to die because it would take time in their search of Clarke and the others.
* ItAmusedMe: His reason for wasting three months worth of precious oxygen on a spacewalk? "It was fun." [[spoiler:It wasn't him that went on the spacewalk, it was Raven. He did make all the arrangements though.]]
* LivingEmotionalCrutch: To Raven. She declares that he's all [she has], that she owes him her life, and that they're family. Some of her more extreme and ruthless actions are to protect him.
* LoveMakesYouCrazy: When he thought Clarke had been taken by the Grounders [[spoiler:he ended up burning down their food shed, rounding them up, holding them hostage in a pen, and gunning down 18 villagers.]]
* TheSocialExpert: Shown to be very good at reading people and knowing how to talk to them, and is the first person to realize Wells is lying about having got Clarke's father arrested.
* TakingTheHeat: As it turns out, Finn isn't actually guilty of going on the illegal spacewalk that got him locked up. [[spoiler: He helped Raven go on a spacewalk and then said he'd done it himself because Raven was eighteen and would have been executed.]]
* YourCheatingHeart: Just as he and Clarke are becoming a couple, she finds out Raven is his girlfriend back in the Ark. In the next episode, Raven finds out he slept with Clarke.
* WhatHaveIBecome: After [[spoiler:he kills a number of villagers]] he lapses into this while alone with Clarke.

-->'''Played by:''' Christopher Larkin

One of the 100. He's a technological genius. He and Jasper were arrested for stealing pharmaceuticals from the Ark.
----

* AdvertisedExtra: Larkin is part of the main cast but Monty gets no major storylines of his own.
* AmbiguouslyGay: Is the only person present not to have any reaction when Octavia strips in the Pilot (the others present are Finn, Jasper, and Clarke, all of whom have since been into other girls), and has yet to show any interest in women.
* AsianAndNerdy: He and Jasper are the resident nerdy guys, insofar as they are very intelligent (Monty is TheSmartGuy until Raven appears), dorky and getting female interest is considered an achievement.
* BreakTheCutie: Season 2 was hard on him. After risking his life multiple times for the sake of the 47, he eventually [[spoiler: helps Clarke and Bellamy kill off all the mountain men. This act clearly left a toll on him and leads to a fallout with Jasper.]]
* CanonForeigner: Not present in the original novel.
* TheConscience: The biggest instance is in the finale, when he asks Clarke one last time if she's sure she wants to [[spoiler: irradiate the entire Mount Weather compound, killing hundreds of innocent people.]]
* FourTemperamentEnsemble: He generally fits the thoughtful, intelligent Melancholic label with Jasper (Sanguine), Miller (Choleric) and Harper (Phlegmatic).
* AFriendInNeed: He's loyal, friendly and will do anything to help his friends.
* FreudianTrio: Monty (Ego), Jasper (Id), and Miller (Superego).
* HeterosexualLifePartners: He and Jasper are extremely close and talk about everything together. They were even arrested for the same petty crime.
* NiceGuy: There's really nothing to hate about Monty.
* OnlySaneMan: He and Miller initially are the only people besides Clarke to think something's up with Mt. Weather. Jasper and the others come around eventually.
* RedOniBlueOni: Blue to Jasper and later Miller's Red.
* TheSmartGuy: Shares it with Jasper and later Raven. He focuses on computer science and is also mentioned to know a lot about plants.
* TeenGenius: He's incredibly smart, and underage.
* ThoseTwoGuys: With Jasper. Jasper and Monty are rarely seen apart and if they are, it's due to extraneous circumstances.
* WhatWouldXDo: Asks himself and Jasper "What would Clarke do?" when faced with the prospect of leaving Mount Weather.

-->'''Played by:''' Devon Bostick

Monty's best friend. They were arrested together for stealing pharmaceuticals from The Ark.
----
* AcquiredSituationalNarcissism: "I Am Become Death": His [=PTSD=]-induced attack on the Grounder peace treaty makes him popular among the rest of the 100 and he lets it get to his head, alienating Monty.
* AlliterativeName: '''J'''asper '''J'''ordan.
* BerserkButton: People getting speared seem to trigger anger, likely because he suffers PTSD from being impaled himself.
* BreakTheCutie: Jasper's really put through the ringer in Season 2. He's quick to trust the Mountain Men before learning that [[spoiler: they plan to use the 47 as sources of bone marrow. He becomes the unofficial leader of the 47 and feels responsible every time one of them dies. He finds an ally in Maya, and they fall in love along the way -- but she dies of radiation in his arms, which he thinks could have been prevented had Bellamy and Clarke just given him one more minute.]] This alienates him from Clarke and Bellamy (both of whom he clearly looks up to) and leads to a fallout with Monty, his closest friend.
* CanonForeigner: Not present in the original novel.
* DoggedNiceGuy: Towards Octavia in season 1.
* EtTuBrute: He has one of these moments with Monty, Clarke and Bellamy after they [[spoiler: kill all the mountain citizens by exposing them to radiation, including Maya]]
* FourTemperamentEnsemble: He easily fits the cheery, easily manipulated Sanguine label with Monty (Melancholic), Miller (Choleric) and Harper (Phlegmatic).
* FreudianTrio: Jasper (Id), Monty (Ego) and Miller (Superego).
* GogglesDoNothing: He wears old military "sun, wind & dust" goggles on his forehead. No explanation is given, and he never puts them on. He's without them for the entirety of season 2 until the end.
* HeterosexualLifePartners: With Monty.
* HopelessSuitor: Octavia has chosen both Atom and then Lincoln over him.
* ILetGwenStacyDie: Played with in "Resurrection." He feels responsible when Fox is dragged away by the guards as he promised her everything would be okay.
* ImpaledWithExtremePrejudice: He catches a spear through his chest in the pilot, but he survives.
* ImprobableAimingSkills: Averted for dramatic effect. Although he's one of the best shooters, he misses the bomb in "I Am Become Death" several times, and everyone would have died if Monty hadn't shown up with an extra round of bullets.
* TheQuisling: In Season 2, he's the most eager to accept [[spoiler: Mount Weather as their new home and the Mountain Men as their people]] -- Monty and the others are a bit more skeptical. This is played with when he sees the Mountain Men [[spoiler: use Grounders as HumanResources. After this revelation, the highers-up see him as this and implore him to invite more of the 47 to "volunteer" their blood, but Jasper is actively working on an escape plan]].
* RedOniBlueOni: Red to Monty and later Miller's Blue.
* RescueRomance: Averted, to his disappointment. He and Octavia grow closer after he saves her from being eaten by a sea snake, but nothing comes of it.
* TheSmartGuy: Shares it with Monty and later Raven. He's the resident chemist.
* ThoseTwoGuys: With Monty.
* TookALevelInBadass: Was somewhat wimpy in Season 1. In Season 2, due to the situation, he's become more of a take-charge kind of guy, and willing to do anything to save his friends.

* CanonForeigner: Not present in the original novel.
* DeathOfAThousandCuts: [[spoiler:What she was nearly subjected to after Gustus frames her.]]
* DontYouDarePityMe: She really doesn't like it when people try to help her [[spoiler:after she gets crippled and has to walk with crutches.]]
* TheEngineer: Actually [[InsistentTerminology The Mechanic]] for the 100, though the distinction isn't important until she's reunited with the Ark people. She makes everything from walkie-talkies to makeshift bombs.
* FourTemperamentEnsemble: She fits the Melancholic label with Clarke (Phlegmatic), Octavia (Sanguine) and Bellamy (Choleric).
* FrameUp: She was framed for attempting to murder The Commander. [[spoiler:It turned out to be her Lieutenant, Gustus.]]
* GreenEyedMonster: Towards Clarke, since she knows that Clarke and Finn slept together. Clarke has since broken off the offending relationship and is trying to keep things peaceful between herself and Raven, but Raven is still pretty angry. Averted as season 1 goes on and she becomes part of Clarke's inner circle.
* ICantFeelMyLegs: Murphy shoots her in the spine in the season 1 finale. They get her to Abby in time, but she's lost feeling in one of her lower legs and has to walk around with a cane or brace. She's ''not'' happy about it, but begins to adjust.
* IOweYouMyLife: She already felt this in spades for Finn before his arrest, but "Spacewalker" shows that he took the fall for her illegal spacewalk so she wouldn't get floated. This is why she's so loyal to him.
* IdiotBall: Raven's plan to free Finn after he gives himself up to the Grounders by having [[spoiler: Clarke kill their Commander would only have resulted in their killing ''everybody''.]]
* KickTheDog: Participates in torturing Lincoln and tries to [[spoiler: sell Murphy up the river in Finn's place as the one behind the massacre]], both in an effort to try and save her boyfriend's life.
* NiceJobBreakingItHero:
** Wasting months' worth of oxygen on an illegal spacewalk likely contributed to the oxygen shortage, which was one of the reasons for the deployment of the 100 and the culling.
** The flares she crafted and shot with the intent of getting the ark's attention blazed an entire village of grounders.
* ParentalNeglect: Her mother was a drunk and did not take care of her.
* SexForSolace: She sleeps with Bellamy in order to get over Finn cheating on her. Later, she admits that it didn't really make her feel better.
* TeethClenchedTeamwork: With Clarke after she finds out she slept with Finn. By the first season finale, they've put it behind them...only to come back in full force in season 2 after [[spoiler: Clarke kills Finn]]. She lashes out at her more than once, but keeps her head straight about it because taking down Mount Weather is more important.
* TeenGenius: Isn't even out of her teens yet and is already considered one of the smartest mechanics the Ark has ever had.
* TheSmartGuy: Increasingly takes over this role from Monty and Jasper once she arrives on the ground, as the 100's lack of technology is a huge problem and it's what Raven's good at.
* WrenchWench: She's an attractive girl who's great with machines. According to Abigail, she's the youngest Zero-G mechanic on the Ark. When asked if she could make an escape pod ready to enter the atmosphere within nine days, she simply answered "Hell yes."

-->'''Played By:''' Richard Harmon

Bellamy's initial right hand thug before getting kicked out of the camp.
----
* AssholeVictim: Nearly gets hanged by a vigilante mob for a murder he didn't commit. We'd be a lot more sympathetic if he hadn't already tried to murder Wells and his would-be executioners didn't consist mostly of people he'd been abusing.
* TheBully: Just one example: When Connor, who's working on building the settlement's defensive wall asks him for water he refuses and when Bellamy tells him to give Connor some he pisses on him after Bellamy has left.
* ButtMonkey: Murphy eventually replaces Wells's ButtMonkey status after he died. He almost gets hanged by an angry mob, gets exiled, is implanted with a virus, and then gets captured again by the Grounders who torture him...again. He makes it back to camp, but the others clearly haven't forgiven him. [[AssholeVictim Although unlike Wells, he actually does deserve it]].
* CanonForeigner: Not present in the original novel.
* TheDragon: To Bellamy, at first, then he went beyond even [[EvenEvilHasStandards Bellamy's bounds]] and gets exiled.
* TheDogBitesBack: In "Murphy's Law", Murphy harasses a kid that needed water before he can continue working. Later the kid was among the others who demanded Murphy's execution. He even ties a gag around his mouth. [[spoiler:In "I Am Become Death", [[EvilIsPetty Murphy kills him, likely as payback]].]]
* EvenEvilHasStandards:
** [[spoiler:Even he's horrified when Finn shot nearly all the innocent Grounders in the village. He tried to stop him before and during the shooting. Clarke accused him of not trying hard enough, and for that [[JerkassHasAPoint Murphy tells her that Finn was looking for her]].]]
** Likewise when [[spoiler: Jaha throws their companion out of the boat to be eaten, so he and Murphy can live]], Murphy is horrified and disappointed.
%%EvilIsPetty
* TheExile: He is kicked out of the camp, on pain of death if he returns, for hunting down and trying to kill Charlotte. He's later welcomed back (kind of).
* FreudianExcuse: He had two loving parents. When he got sick, his dad tried to steal medicine (which wouldn't help) and got floated. His mom succumbed to alcoholism, until she got sick, and her dying words are accusing her son of murdering his dad.
* HeelFaceTurn: Subverted. After his return from exile he appears to be doing his best to fit in and help. Then he murders Connor, and later tried to kill Bellamy. Seems to be for real in Season 2, even though he has his rude moments he honestly does try and help everyone.
* HeelFaceDoorSlam: Clarke and Raven make sure he knows they haven't forgiven him.
* IntergenerationalFriendship: Forms one with Jaha, ''kind of'' -- the latter is pretty much losing his mind over the duration of their journey.
* {{Jerkass}}: To everyone and anyone, even Bellamy. This does result in him getting his ass kicked and being treated like dirt quite a bit and is what results in the group trying to hang him when they suspected that he killed Wells.
* JerkassHasAPoint: When Bellamy refused to hang Charlotte for murdering Wells, he correctly points out that they had no issue letting him be hanged for it and he wasn't even guilty.
* LastNameBasis: Everyone calls him Murphy.
* NeverMyFault: He doesn't seem to grasp why people would be more willing to hang him than Charlotte, regardless of his innocence in Wells' death. Once he returns to the camp, he is constantly mistrusted and reviled, and thinks he's the victim in all this. Suppose all that murdering, attempted murderering, torture, bullying and general being a dick should just be swept aside?
* ReformedButRejected: He's shaped up quite a bit by season 2, but the others still clearly don't trust him. This is part of the reason he's so willing to go with Jaha on his journey.
* {{Sadist}}: Holds a girls face to the fire while taking off her bracelet. He claims it's for realism's sake but he was clearly getting off on it.
* TookALevelInKindness: He's a lot more tolerable in Season 2.

* {{Badass}}: He is one of the more capable members of the 100, and during the Grounders assault on the dropship he kept fighting even after taking a spear to his right shoulder. He even takes down Anya in one hit.
* BerserkButton: Messing with his dad doesn't sit well with him.
* TheBigGuy: Particularly for the 47 who are trapped in Mt. Weather. He is one of the biggest and most physically capable members of the group and puts his strength to good use when bashing a wall in with a sledgehammer to expose the communications lines.
* BrutalHonesty: Even if the other characters don't like it.

* BadDreams: Frequently had nightmares of Jaha killing her parents.
* ChildrenAreInnocent: Zig-zagged. She murders Wells in cold blood but seems to have very little understanding of the consequences of what she has done.
* DrivenToSuicide: Eventually jumps off a cliff due to the guilt caused by her murder of Wells and the uproar this causes in the camp.

* GenderBlenderName: Monroe is a more common name for boys than girls.
* ThoseTwoGuys: With Sterling in season two, [[spoiler:until Sterling dies]].
* TookALevelInBadass: During the Grounders attack on the dropship, she ran away after running out of ammo instead of fighting, and it is later hinted that she and Sterling fled the battle when the Grounders began to overrun the camp, which is why they avoided being captured by Mt. Weather. She gets braver after psyching herself and Sterling up in order to rescue Bellamy and Finn from Tristan, and later provides covering fire by herself for the others while they rescue Mel.

* BrutalHonesty: Chancellor Jaha outright admits to the 100 that the reason they were chosen for this mission was that their crimes made them expendable.
* DeathSeeker: During the first season, his two criteria for solutions to the many problems of the Ark seem to be "Will it solve the problem?" and "Can I somehow justify dying while implementing it?".
* DesperatelyLookingForAPurposeInLife: He's gotten a little obsessive over the idea that he survived 'for a reason'. Searching for the City of Light is part of it, he thinks he was chosen to lead his people to salvation.
* TheDeterminator: Becomes one in Season 2, after some words of encouragement from an image of his son.
* EvilChancellor: [[SubvertedTrope Subverted.]] He seems like this and is viewed this way by some of the 100, but in actuality he is a ReasonableAuthorityFigure who tries his best to avoid needlessly executing people.
* GoingDownWithTheShip: In "We Are Grounders, Part Two" [[spoiler: he makes a HeroicSacrifice by staying behind to manually disengage the final Dropship from The Ark, even though this means he cannot go with them. Subverted as he manages to save himself through a HelpfulHallucination of his son and get down to the ground.]]
* MeaningfulName: [[spoiler: As pointed out by the AI he finds]], Thelonius means "lord or ruler" (as he's the leader of the Ark at the beginning).
* ReasonableAuthorityFigure: He saved Clarke's mother from being thrown out of the airlock because she is a good doctor and saved his life, even if the means she used were illegal.
* SanitySlippage: Goes through this post-"Spacewalker" on his quest to find [[spoiler: the City of Light,]] becoming less of TheGoodChancellor and more of a semi-religious fanatic.
* SillyRabbitIdealismIsForKids: Seems to have taken this up in Kane's stead near the mid-season finale. While he was more extreme in trying to push the members of Camp Jaha into fleeing, he did have a point in that relying on Clarke was pushing it because if she was wrong they were going to be eliminated and that sacrificing Finn would be the best alternative.
* SupportingLeader: Of the Ark in the first season.

-->'''Played by:''' Paige Turco

Clarke's mother. She is a government official on the Ark, and a surgeon.
----
* AngerBornOfWorry: When Raven helps Clarke escape from camp she slaps her before she even realizes it.
* TheChainsOfCommanding: After becoming Chancellor she has to deal with the stress of trying to keep everyone alive, knowing that it could mean war with one wrong decision. [[spoiler:Worse, most of the Grounders see Clarke as the leader of their faction.]]
* TheHeart: Plays the role for the senior staff of the Ark. Continually trying to keep everyone alive. Essentially acts as the MoralCompass.
--> '''Abby:''' I choose to make sure we deserve to stay alive.
** When Clarke starts resorting to more ruthless actions, Abigail plays this to her as well:
-->'''Abby:''' Try to remember that we're the good guys.
* InSeriesNickname: Her colleagues call her "Abby."
* LastMinuteReprieve: In the Pilot, Abby is in the airlock and the security officer has his hand on the button to open the outer door when the Chancellor arrives to pardon her.
* TheMedic: Resident doctor on the Ark.
* ScrewTheRulesImDoingWhatsRight: She saves Chancellor Jaha even though it means breaking the law by using more than the allowed amount of medical supplies. It may have been to make up for getting her husband killed.
* SparedByTheAdaptation: In the book, Clarke's mother was executed alongside her husband.
* SupportingLeader: After taking on the Chancellor title after Kane.
* WideEyedIdealist: She firmly believes that Earth is safe to inhabit, even in the absence of any proof. [[JustifiedTrope Justified]], since she has a daughter down there and doesn't want to believe that she is dead.

Chancellor Jaha's second-in-command on The Ark. Unlike Jaha, he believes in rigidly enforcing the law.
----
* CanonForeigner: Not named in the original novel.
* MyGodWhatHaveIDone: When they make contact with Earth and learn it's survivable, he feels this as he looks over the memorial for the 320 people he sentenced to death. His greatest regret is that if he had just waited ''three'' more days it wouldn't have been necessary.
* NameOfCain: Subverted. Although Kane initially appears sketchy and power-hungry, he does genuinely have the best interests of the Ark at heart, and works towards them even if his methods aren't often the best.
* NeverGotToSayGoodbye: His last words to his mother were disdain and refusal to participate in a religious ritual that mattered to her.
* OohMeAccentsSlipping: Henry Ian Cusick doesn't quite pull off Kane's American accent.
* ReasonableAuthorityFigure: Becomes one by the end of Season 1 and in Season 2.
* RedHerring: Is made to look like a major antagonist and the one behind the assassination attempt on Jaha. He's not.
* RedemptionEqualsDeath: Averted, twice. Once when someone has to stay behind to launch the Ark, Kane volunteers, but Jaha gets there first. Secondly, when they are imprisoned by the Grounders, [[ItMakesSenseInContext Kane attempts to kill himself so that Jaha won't die.]] This trope is even discussed with Abigail.
--> '''Abigail:''' You're only Chancellor because Thelonius beat you to redemption.
* SheatheYourSword: He takes this approach when trying to make peace with the Grounders after imprisoning one of them. [[spoiler:It gets him tossed into their version of a prison.]]
* SillyRabbitIdealismIsForKids: He establishes his WellIntentionedExtremist credentials by callously responding to Callie's pleas that he spare her friend by telling her that friendship is a luxury they can't afford. [[spoiler:He goes on the other end in Season 2, wanting peace despite the risks later on.]]
* WellIntentionedExtremist: He claims that everything he does is to ensure mankind's survival, whether or not its nice.

A high-ranking engineer.
----
* TheEngineer: He was responsible for keeping the Ark together and running smoothly. After arriving on Earth, Sinclair oversees the construction of Camp Jaha and its defenses. He also brings equipment and men to help recovery operations in Tondc after [[spoiler:it is hit by a missile from Mount Weather]].
* OnlySaneMan: He is the only major leader on the Ark who stays out of the power struggles and simply tries to do his job.
* ReasonableAuthorityFigure: Easily the most reasonable and friendly leader on the Ark, and he even cleared Raven for spacewalks after she was initially denied permission due to a minor heart condition because he recognized her talents.

* TheEngineer: Works with the Ark's technology. Keeps this up when they land on the ground.
* ScrewTheRulesImDoingWhatsRight: In "Human Trials" he briefly shuts off the power to the electric fence around Camp Jaha so that Clarke, Bellamy, and Octavia could sneak out to find Finn and Murphy.
* SecondLove: He's heavily implied to have it bad for Raven, as shown when he specifically asks her to work with him on a radio beacon. He even designed a brace for her leg. They slowly grow closer in the latter half of season 2.

!!Diana Sydney
-->'''Played by:''' Kate Vernon

Ex-chancellor who talks her way into a council position.
----
* KarmicDeath: Extremely eager to get her people and some of the working class off the Ark, everyone else be damned. The ship then crashes into the ground and explodes due to its systems being jammed by the Mountain Men.
* TheManBehindTheMan: Diana was the one behind the head guard orchestrating Jaha's murder.
* ManipulativeBitch: She was a very charismatic politician who knew how to turn people over to her side. Too bad her "side" involved launching the Exodus ship and crippling the Ark.
* NeverFoundTheBody: She's killed when the Exodus ship explodes, and her body is never found.

!!Jake Griffin

Father to Clarke and husband to Abby, Jake was an engineer on the Ark. He discovered a flaw in the oxygen systems that eventually led to his execution.
----

* DisappearedDad: To Clarke, who loved him dearly. His death is the reason for her tense relationship with Wells, then with her mother.
* HeKnowsTooMuch: He was executed because someone ratted him out before he was going to reveal the truth about the life support systems, which would have caused mass panic.
* NiceGuy: From what we know of him, he was idealistic, honest, loyal and devoted to his family, and thought that everyone on the Ark should have a fair shot at life.

-->'''Played by:''' Ricky Whittle

A native of the surface who has been watching the 100. Currently exiled from his Clan for siding with them. He is the closet thing the 100 have to an ally on the planet.
----
* AloofAlly: Becomes this to the 100 after bonding with Octavia. He's gruff and terse and most of them avoid him, but he helps where he can.
* AnnoyingArrows: Been shot twice, once in the chest and the other time near the kidneys. Both times treats such wounds as trivial.
* TheAtoner: Shows deep regret for his actions [[spoiler: as a Reaper]] and volunteers to accompany Bellamy to Mount Weather in order to face it.
* {{Badass}}: He used himself as bait for the Reapers and managed to come out alive and unscathed.
* TheBait: Twice, once to lead the Reapers away from Finn and Clarke. The second time he and Finn were this to the Reapers leading them to the Grounder invasion force...
* BeardOfBarbarism[=/=]BeardOfEvil: upgrades his PermaStubble to this [[spoiler: after being turned into a Reaper. It becomes a short-lived BeardOfSorrow after Clarke and Abby detox him]].
* CategoryTraitor: His people consider him one after he helps out the 100.
* CombatMedic: Was the Grounders' healer originally. Shown to be able to hold himself in a fight as well.
* CulturalRebel: According to Indra in "Blood Must Have Blood, Part One", he always questioned his people's way of life. Helping the 100 made him more of an outcast.
* DefectingForLove: Octavia is the catalyst for his leaving his people.
* HeroicWillpower: Averted, then played straight later. [[spoiler: When trying to smuggle Bellamy into Mount Weather, he defects back to the Reapers when offered more [[FantasticDrug Red.]]]] In the second season finale, [[spoiler: he overcomes both this temptation and his fear of the tone generator in order to kill Cage.]]
* MrFanservice: Is the most ripped of the main cast and obviously the one that gets the most {{Shirtless Scene}}s.
* MyCountryRightOrWrong: Averted, originally aided the 100 due to Octavia, he has shown to assist multiple times due to the fact that he believes what his people are doing is wrong.
* TheQuietOne: He's noticeably less talkative than any other major character.
* TheStoic: After being captured by the 100, Bellamy tortures him. He never says a word, and only gives them the information they need after Octavia willingly poisons herself.
* StarCrossedLovers: Technically he and Octavia comes across us this. She was born in Space and lived under ground. He was born on Earth and is a Grounder. His people see her people as Invaders and her people see his as savages determined to wipe them out.
* TragicMonster: He gets tortured, reprogrammed, biologically modified and addicted to drugs by the head of Mount Weather's security. [[spoiler:Effectively turning him into a bestial Reaper agianst his will. He gets better.]]

-->'''Played by:''' Dichen Lachman

An authority figure for The Grounders. She meets with Clarke to discuss a peace treaty.
----
* ActionGirl: Possibly the most badass female Grounder on the show.
* BadassBoast: In a last desperate attempt to salvage the peace talks, Clarke warns Anya that once the Ark soldiers come to Earth, they'll wipe out The Grounders. Anya responds that they've survived much worse.
* BadassLongcoat: Seems to be a signature getup shared by her and Commander Lexa, her former second. It's distinctive enough to suggest that the untouchable Heda might have had [[HeroWorshipper some inspiration]] in her formal getup.
* CharacterDeath: [[spoiler:She gets shot by members of the Camp Jaha right after parting with Clarke after agreeing to try and work towards peace.]]
* DualWielding: She dual-wields two long blades in the first season finale.
* EnemyMine: She and Clarke have to work together to escape Mount Winter.
* TheLeader: Subverted. Her group's only part of a larger faction, although she does have the authority to call for a truce.
** DemotedToDragon: When Tristan shows up and reveals the Grounders Commander put him in charge, she steps down.
* {{Hypocrite}}: While her points about the flares burning down the forest and Lincoln's torture do make sense, her accusations against the 100 seem to overlook the fact the Grounders impaled, kidnapped, and tortured Jasper before leaving him as bait for exploring territory they had no idea belonged to the Grounders, or that Lincoln's torture was in response to him kidnapping Octavia, holding her against her will, and stabbing Fin with a poisoned knife that nearly killed him. She blames the 100 for starting the war, but it was her side who acted violently first and started the conflict.
* TheMentor: Was previously one to the current commander.
* OccupiersOutOfOurCountry: Or off our planet, in this case. To her, The 100 are hostile invaders and she doesn't trust their offer of peace, seeing it either as a trap or a cheap attempt to avoid the war that they started.
* ShaggyDogStory: She and Clarke fight tooth and nail to get out of Mount Weather before Clarke offers to broker a truce between their people. Anya agrees, and [[spoiler: is shot by Camp Jaha guards]].
* ShadowArchetype: At first glance, she comes off as a darker version of Clarke: She's in a position of authority among The Grounders and clearly values the lives of her people enough to at least show up to a PeaceConference, but she has a much harsher attitude than Clarke and seems much less inclined to believe that peace is actually possible. [[JustifiedTrope Justified]] in that Clarke was raised by loving parents who taught her to value others' lives, while Anya was raised an a hostile DeathWorld where aggression and territorial paranoia are the only things that keep you alive.
* UngratefulBitch: She knocks Clarke out and takes her back to her people as a prize, despite the fact that Clarke put her life on the line to rescue Anya.
* VillainHasAPoint: While an antagonist to the 100, she points out they are trespassers on their land, which lead to Jasper being impaled in the pilot. Also, Bellamy did lead an intruding party despite the clearly marked warning. For Anya, the two people the Grounders have killed for trepassing on their land amounts to nothing compared to the whole village burnt down by the 100's flares. Clarke's offer of making peace now or the rest of the Ark wipes the Grounders out later didn't impress Anya either.
* WhatTheHellHero: When she accuses The 100 of being invaders, Clarke counters that they didn't know that anyone else was alive on Earth. Anya responds that they knew The Grounders were there when they led a raiding party onto Grounder territory, captured and tortured Lincoln, and burned down a Grounder village with their flares. (Though this last one was an accident.)
* WorstAid: Anya removes a tracker planted in her skin by ''biting down on the section of skin and then ripping it out''. She doesn't screw around.

-->'''Played by:''' Alicia Debnam Carey

Leader of the Grounders.
----
* ActuallyThatsMyAssistant: Has her bodyguard Gustus pose as the Commander while she pretends to be a slave girl. Jaha and Kane are shocked when they find out that the girl who waited on them for two days was actually the Grounder leader.
* AsskickingEqualsAuthority: She ''earned'' her position, and it's made clear that if she was weak she'd be killed by her own men.
* BadassGay: She became [[AsskickingEqualsAuthority leader of twelve clans]] through sheer badassery, and has only been explicitly attracted to women.
* BadassLongcoat: Part of her usual commander getup, combined with a long red ScarfOfAsskicking that trails from her shoulder pad.
* BeneathTheMask: Despite her LoveIsAWeakness facade, she often shows a gentler, softer side.
* BornAgainImmortality: She states that when she dies, her spirit will choose the next Commander and be reborn.
* CommandingCoolness: The highest-ranking leader of the Grounders with a rank of "Commander."
* FacialMarkings: Like many of the Grounders, she wears heavy black eye makeup and also a gold wheel-like adornment on her brow, probably to signify her as leader.
* KnifeNut: Her usual weapon of choice, including a long machete-like blade and she's deadly with throwing dagger as well, putting it through the hand of one of her fellow Grounders after threatening Clarke.
* IDidWhatIHadToDo: Lots and lots of times, the two major ones being [[spoiler:letting the site of her war council be bombed because evacuating more people than herself and Clarke would have tipped off the Mountain Men that their communications were being intercepted]] and [[spoiler:abandoning the forces of Camp Jaha after having negotiated the release of the Grounder prisoners from the Mountain Men.]]
* IronLady: She's renowned even by other Grounders for her ruthlessness
* LadyOfWar: She's her people's leader, is always [[TheStoic calm and composed]], and, by the standards of her Barbarian Tribe, she dresses and acts rather regally. She hasn't had too many fight scenes, but when she does fight, it's with a swift and graceful economy of movement.
* LoveInterestTraitor: Played with. [[spoiler: She admits her feelings for Clarke before kissing her, and then the next day on the battlefield, she invites Clarke to join her in the Grounder Capitol. Then during the battle, Lexa was offered a deal with the Mountain Men she couldn't turn down -- even though it meant betraying Clarke.]]
* LoveIsAWeakness: She began to believe this after her girlfriend was tortured and killed by an enemy clan who thought she knew Lexa's secrets.
-->'''Clarke''': So you just stopped caring? About everyone? ''(Lexa nods)'' I could never do that.\\
'''Lexa''': Then you put the people you care about in danger, and the pain will never go away.
* NeverBeHurtAgain: When her girlfriend was killed because of her power, Lexa decided that the best way to stop her (and anyone else close to her) affecting her was to close herself off to all feelings.
* ReasonableAuthorityFigure:
** It's mentioned that she's a visionary and, rather than simply charging and killing Camp Jaha, she gives them a chance to retreat and when they prove they can turn Reaper's back to normal they are willing to enter a truce so long as [[spoiler: Finn pays for the 18 he killed. When Clarke kills him and denies them the execution, she tells them that its done rather than let them have Clarke.]]
** She also is shown to acknowledge the distinction between killing in a war and outright murder: Clarke originally tries to offer herself in place of Finn, citing that she burned three-hundred Grounders alive. The Commander refuses the offer, saying that Finn is the one who is guilty.
** Concedes that assassinating her would in no way benefit the Sky People and turns on her loyal bodyguard when he confesses.
* SecretTestOfCharacter: Disguises herself as a slave girl attending to Jaha and Kane's cell in order to listen in on their discussion and judge if their desire for peace was genuine. They pass, and she gives the truce a chance.
* SergeantRock: She cannot show weakness to anyone, not even her men. But she does care for them dearly.
* TheStoic: Hardly shows any emotion. A notable exception is when she's forced to kill her bodyguard; she looks visibly shaken afterwards.
* SupportingLeader: The highest-ranking member of the grounders, she commands the military forces. She united a coalition of twelve different clans under her banner.
* TheWomanWearingTheQueenlyMask: Implied to be this; she notably became more closed-off and ruthless after Costia's death so she could better lead her people.
* YoungAndInCharge: She's obviously far younger than a lot of the Grounder warriors she commands.

!!Tristan

-->'''Played by:''' Joseph Gatt

Another commanding figure among the Grounders, though with more authority than Anya and the ultimate goal of wiping out the 100.
----
* BigBad: Serves as this to the 100, considering he is the one leading the assault on them. Turns out to be a DiscOneFinalBoss.
* BoomHeadshot: Courtesy of [[spoiler: of Kane. He ends up meeting his end this way.]]
* DiscOneFinalBoss: The 100 thought that the Grounder invasion (headed by Tristan at the time) was the biggest threat to their life on Earth. They're wrong -- he's taken out easily at the start of season 2, and the Mountain Men are bigger fish to fry.
* {{Foil}}: If Anya is one to Clarke, then Tristan is one to Bellamy. Both are serious, ruthless leaders that wish for nothing short of their enemies' complete genocide. Differences again kick in when factoring in that Bellamy is a violently protective older brother that looks out for others, whereas Tristan seems to care very little for other people. Both also showed no problem with torturing enemies.
* TheStoic: Shows little to no actual emotion.
** NotSoStoic: However he tends to have an active fight or flight reaction when [[{{TheDreaded}} Reapers are involved.]] Then again there are [[NightmareFuel very good reasons for that.]]

* LadyOfWar: She has a certain fierce regality about her.
* MeaningfulName: Shares a name with [[http://en.wikipedia.org/wiki/Indra Indra]], the warrior leader of the Hindu gods.
* TheMentor: She decides to take Octavia as her second and train her in the art of combat.
* PetTheDog: In "Blood Must Have Blood" [[spoiler: she gives Lincoln the choice of whether or not to escape and help out the Sky People, knowing he cared deeply about Octavia, despite Lexa having just broken their alliance]] and showing notable distrust for the Sky People previously.
* TeethClenchedTeamwork: With the Sky People. After what happened with Finn and her village, this is understandable.

* ShadowArchetype: To Bellamy, who shares his unquestionable devotion to the people close to him and the willingness to go to extremes for them. In Gustus's case, he was ready to renew hostility between Camp Jaha and the Grounders all because the alliance would endanger Lexa. Bellamy shares this train of thought when he immediately pins Gustus as the perpetrator, and acknowleg admits later that it just "made sense" to him.

One of the doctors of the Mountain Men.

* EvilCounterpart: To Abby.

* KarmicDeath: [[spoiler:When the floor gets irradiated, Jasper makes damn sure that she's the one who dies since she was harvesting their blood to prevent it.]]

* MadDoctor: She performs inhuman experiments behind the back of her superior in order to get bone marrow of the 48 and subject her own people to cruel treatment in the name of science.
* MorallyAmbiguousDoctorate: Sees no problem with [[spoiler:keeping Grounders in cages and harvesting them for their blood]] or [[spoiler:killing an innocent girl with radiation]] for the sake of research.

Added DiffLines:

* {{Hypocrite}}: While her points about the flares burning down the forest and Lincoln's torture do make sense, her accusations against the 100 seem to overlook the fact the Grounders impaled, kidnapped, and tortured Jasper before leaving him as bait for exploring territory they had no idea belonged to the Grounders, or that Lincoln's torture was in response to him kidnapping Octavia, holding her against her will, and stabbing Fin with a poisoned knife that nearly killed him. She blames the 100 for starting the war, but it was her side who acted violently first and started the conflict.


* DeadpanSnarker: Has a knack for this.
--> '''Bellamy:''' You figured that impaling people on spears is code for "let's be friends"? Have you lost your damn mind?
