The Grounders

The Grounders or Outsiders (by the Mountain Men) is a term used to describe a person who was born on Earth rather than in space or Mount Weather. The Grounders alive in the present are descendants of humans who survived the nuclear apocalypse 97 years ago. 56 years before the Delinquents arrived on Earth, the Mountain Men first discovered the Grounders were able to walk above ground and were immune to the radiation. Sometime during 2140s, Commander Lexa united all 12 grounder clans for the first time, forming the most influential political factions to emerge in the post-apocalypse, the Coalition with each clan having its own chief and being made up of multiple villages scattered throughout the Eastern Seaboard. Each clan also has its own ambassador to the Coalition, who represents the clan's interests before the whole. The Grounders (particularly the Trikru) had a hostile relationship with the Delinquents also called "The 100" when they first landed on Earth in their territory and after the 100 accidentally burn one of their villages to the ground, the Grounders retaliated and a conflict broke out. The 100 along with the other survivors of The Ark become known as The Sky Peoplenote  and they decide to try to make peace with the Grounders. At first, Lexa was willing to extend peace to the Sky People provided that the Sky People leave their territory. Eventually, the Sky People and the Grounders form an alliance to take on their mutual enemy, The Mountain Men. Months later after The Mountain Men are defeated they maintain a fragile truce with the Sky People.

    The Grounders As A Whole
Jus Drein Jus Daun! (Blood Must Have Blood)
"You think our ways are harsh, but that is how we survive."
—- Commander Lexa to Clarke

12 Clans: Trikrunote , Azgedanote , Floukrunote , Sankrunote , Yujledanote , Ouskejon Krunote , Delfikrunote , Trishana(kru)note , Podakrunote , Ingranrona(kru)note , Boudalan(kru)note , Louwoda Klironnote 
The Commander: Beccanote , Malachinote , Lexanote , Ontarinote , Madinote 
Clan/Tribe Leaders: Azgeda: Nianote , Roannote  Trikru: Anyanote ,Indranote  Floukru: Lunanote 

Tropes that pertains to all Grounders and their society as a whole.

  • Action Girl: Most of the leaders are women and they are also skilled warriors.
  • Always Chaotic Evil: Subverted. The Grounders seemed this way at first to the 100 when they spear Jasper and they start killing other members later on. The Grounders are shown to have a violent culture and live by rules and traditions that seem barbaric and without reason to the 100, the Sky People and Mount Weather, but it is later shown that they live that way as a means to survive and that they lived that way for so long they don't know how to live any other way. Most of the Grounders fear that the Sky People will use their superior technology and weapons to wipe them out and thus believe that they should strike first.
  • Asskicking Leads to Leadership: Only the strongest become the leaders of their clans/villages and the main leader known as "The Commander" is decided in a contest where they have all the nightbloods fight each other to the death. As shown with Lexa, the commander must always show strength to keep their position or the clans can either vote them out or they can be challenged by one of the other leaders, both of which will result in the commander's death because of the Grounder's belief in reincarnation.
  • Anti-Villain: Their antagonism towards the main characters in the first season is because Clarke, Bellamy, and the other "100" unintentionally killed several of their people and the Grounders assumed they were invaders who had declared war on them. This got worse when the 100 armed themselves, started killing in self-defense and captured and tortured Lincoln to save Finn. Jasper panicking and firing the first shot at the peace conference just sealed the deal.
  • Anyone Can Die: The show has not been kind to the Grounders. Of all the named Grounder characters only a few are still alive by the end of Season 6 (Emori, Echo, Indra, Niylah, Gaia, Madi). Significant deaths of named grounder characters include Lexa, Lincoln, Luna, Roan, and Anya along with several other grounder characters who don't even make it out of the season they're introduced in.
  • Badass Army: Most grounders are skilled in hand-to-hand combat and with swords, spears, knives/daggers, and bows and arrows and have been trained since birth. Their armies are a force to be reckoned with because of their individual skills and is why despite the fact that they have guns and other advanced weaponry the Sky People have almost no chance of beating them in an ongoing war.
  • Badass Creed: Jus drein jus daun ("Blood Must Have Blood")
  • Blood Knight: Most Grounders enjoy fighting and consider it an honor to die in combat.
  • Body-Count Competition: Grounders keep track of their kills through scars/tattoos on their body. Their leader Lexa was exempt from this practice because she has killed too many people to allow for kill marks.
  • Child Soldiers: Grounders are trained to fight since childhood and some of their warriors are children and teenagers who are known as "Seconds" when they are being trained by the clan leaders. Lexa was a Second to Anya and became the Commander at age 12 and is in her early 20s when the 100 arrive on the ground, prompting Abby to say "They're led by a child."
  • Combat Pragmatist: The Grounders are not above using biological warfare on their enemies and they are capable of doing sneak attacks, setting up traps, and they are also willing to wipe out a whole group/clan/population if it seems that leaving any of them alive will become a problem later on. They are also justified in using these methods since they have enemies who have access to guns and other weapons. Generally the Grounders will rely on having a superior force by uniting all the clans to wipe out a common enemy.
  • Culture Justifies Anything: In Grounder culture children can be warriors and they also have the Nightblood children compete in a fight to the death known as the Conclave to decide who the next commander will be. Their method of executing a criminal or an enemy is to torture them to death more painfully if this person has killed any other Grounders, and based on how many they killed the Grounders make them feel the pain of each life they've taken, which includes cutting them, burning them, and dismemberment. They are also willing to wipe out their whole enemy's tribe or people including the children, even including the people who weren't trying to fight or did anything wrong.
  • Enemy Mine: In Season 2, they enter an alliance with the Sky People to take on the Mountain Men who also created and control their most feared enemies, The Reapers.
    • Overall all the clans will put aside their differences to destroy a common enemy and this is what they were originally going to do against the Sky People.
  • Expy: Their culture has elements of Native American culture and Viking culture. They are even called "savages" by Dante and others in Mount Weather which is a word used to insult Native Americans and their conflict with the Sky People has similarities to the conflict between the Native Americans and the early English Settlers and the Vikings conflict with Europe and other countries.
  • Fantastic Racism:
    • The Grounders and the Sky People have a mutual distrust of each other for justifiable reasons.
    • Some of the people in Mount Weather see the Grounders as savages which is why they have no problem experimenting and forcibly taking blood transfusions from them. It's implied to be why Dante never attempted to have the Grounders breed with his people like he wanted with the Sky People.
    • The Grounders have a tradition of banishing children who are born with deformities and their families into the desert because they see them as "bad luck" and if they ever return the Grounders have them killed.
  • Fantasy Gun Control/Does Not Like Guns: Grounders are afraid to use guns because of legends that if a Grounder picks up a gun the Mountain Men will come and take them. They still refuse to use guns for a long time after everyone in Mount Weather is dead.
  • Great Off Screen War: Before the events of the show, the Trikru and the Azdega were at war with each other until Lexa initiated them into the Coalition. It is also implied that all the clans have been at war with each other at one point or another.
  • Honor Before Reason/Revenge Before Reason: Their conflict with the 100 was because they refused to accept that the 100's actions against them were a combination of accidents, self-defense, and general misunderstandings. They instead saw the 100 as invaders who wanted to wipe them out. They also saw avenging the people that the 100 killed as a way of honoring them so they couldn't let the deaths go unanswered even if they were accidental or justified.
  • Hufflepuff House: Despite the fact that their are twelve different Grounder clans only three ever get any major spotlight, Trikru, Azgeda, and Floukru, the latter two not even appearing in any substantial way until Season 3. Little information is provided about the other nine clans and characters from those clans have so far only been used as minor and background characters.
  • Gender Is No Object: Grounder society is gender equal, with women acting alongside men as leaders and warriors.
  • Pay Evil unto Evil: Their code of "Blood Must Have Blood" is based around this.
  • Tribal Face Paint/Facial Markings: The Grounders wear war paint on their faces. They also have facial and body tattoos and/or tribal cuts and scars signifying how many people they have killed in battle or which clan they are from.
  • Violence is the Only Option: Their culture is based around this belief and it wasn't until Lexa became commander that they started exploring other options to resolve conflicts which resulted in the formation of the Coalition.
    • It is shown that several grounders felt that Lexa should just wipe out Skaikru instead of trying to have an alliance with them and this perceptive later causes a conflict with the Azdega and the attempt to remove Lexa from the throne.
    • This also becomes a topic of discussion when after the actions of Pike against her people, the Grounders again want to wipe out the Sky People and are against Lexa's decision to not retaliate.
  • Wild Card: In their truce with Skaikru because they were at first not interested in allying with them against Mount Weather until Clarke and Abby successfully cured Lincoln of being a reaper with the implication that they could do this with others and didn't fully agree until Finn's death which they demanded as a condition of the truce. In general the alliance is proved to be very fragile because of both sides not fully trusting each other and the Skaikru having to deal with the possibility that the grounders will wipe them out.
    • Then the biggest problem was that the grounders care more about the well being of their own people which lead to Lexa making the deal with Mount Weather to have the grounder prisoners released on the condition they let them have the sky people by abandoning them.

The Tree People (Trikru)
Symbol Of The Tree People

The Trikru, also known as the Woods Clan, People of the Woods, Trigedakru, and Tree People, are a Grounder Clan that inhabit the expanse of woodlands around the area in which the Sky People landed. Their borders also extend to the location which was once Washington, D.C. but is now known as Tondc. Their largest city and capital is Polis and is where the Commander resides.

They were the primary antagonists of the first season and the first half of the second before entering an alliance with the Sky People.

     The Tree People As A Whole 
  • Anti-Hero: When they enter into an alliance with the Sky People in Season 2, they officially become good guys. Though they also practice questionable traditions and it is made clear that they are willing to kill all the Sky People if they ever make a wrong move, but they are capable of working with them to the benefit of both of their people.
  • Anti-Villain: Their grievance with the 100 was that when they shot up the flares to try and contact the Ark, the flares burned down one of their villages and Anya and the others saw this as an official declaration of war from them.
  • Big Bad: In Season 1, they are the main group the 100 come into conflict with because of landing in their territory, represented by Anya, who ultimately deferred to Tristan, at least with regard to their conflict against the 100.
  • A Lighter Shade of Grey: The Trikru are this compared to the Ice Nation who's Queen is known to be more ruthless than Lexa who is at least willing to make peace. This is really shown in the first half of Season 3 and implied in Season 2.
    • Also in Season 2, they are this to the Mountain Men making Clarke and the others willing to form an alliance with them and the other clans.

Character Appearances: Season 2-Present(Recurring Character)

"We're at war, and a warrior does not mourn those she's lost till after the battle is won."

Leader of the village of Tondc and part of Lexa's inner circle. Notably mistrustful of Camp Jaha.

  • Action Girl: As competent in a fight as any male Grounder.
  • Aloof Ally: In Season 3, she helps Kane, Bellamy, and the others try to find Clarke and it is implied that she been helping out the Sky People since after the events of Season 2 by having secret meetings with Kane.
    • Goes back to this for a time in Season 4, due to Skaikru's alliance with Azegeda.
  • Can't Kill You, Still Need You: How she sees her alliance with Pike to take on A.L.I.E and tries to invoke this on Octavia as well, who also wants to kill him.
  • Covered with Scars: Her face has numerous scars.
  • Does Not Like Guns: She knocks a gun out of the hands of one of her solders because of her people's belief about guns and in Season 3 it is shown that she is still hesitant about them when she refuses to take one when Kane offers one though this is later subverted when she starts using guns in order to help fight A.L.I.E..
  • Lady of War: She has a certain fierce regal quality about her.
  • Meaningful Name: Shares a name with Indra, the warrior leader of the Hindu gods.
  • My Country, Right or Wrong: Indra always obeys Lexa even if she doesn't agree with her decisions as it is shown that she doesn't agree with having an alliance with the Sky People because for one thing what Finn did to her village and felt that Lexa should just wipe them out. She also didn't agree with the retreat from Mount Weather and Lexa making that deal which leads to her decision to secretly let Lincoln go. Even then in Season 3 it is implied that she was secretly helping Kane and the Sky People for months and even later trying to help them find Clarke when it is discovered that the Ice nation is hunting her because Lexa ordered her too.
  • The Mentor: She decides to take Octavia as her second and train her in the art of combat.
  • Number Two: Becomes Octavia's second in command once she becomes the leader of Wonkru even offering to help kill Skaikru for her when it looks like they wont agree to Octavia's terms for the bunker.
  • Odd Friendship: Indra and Kane form a surprisingly close friendship between the Season 2 and 3 Time Skip with the two providing correspondence between their two peoples.
  • Parental Substitute: Indra becomes a surrogate mother figure to Octavia even after she banishes her from being her second to the point that her actual daughter notices their bond and is understandably jealous.
  • Pet the Dog: In "Blood Must Have Blood" 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.
  • Survivor's Guilt: She temporarily loses her will to fight after being the only one spared in Pike's massacre.
  • The Stoic: Indra always has her emotions in check but is Not So Stoic when she gets angry or doesn't agree with an order.
  • Teeth-Clenched Teamwork: With the Sky People.
    • After what happened with Finn and her village, this is understandable. By Season 3, Indra has no problem working with them and in fact has frequent meetings with Kane and provides him information.
    • She is later forced to work with Pike who massacred her people(only sparing her) to take on A.L.I.E and even implies to him that when the situation is over she will have her revenge and kill him.
  • This Is Unforgivable!: How she felt about Finn massacring her village and she is really angry about Clarke mercy killing him because she wanted him to suffer under their "justice". She tends to feel this way about most of the Sky People's actions against her people and why she is so hostile against them and was originally hostile towards Octavia and she also didn't agree with Lexa making the agreement and creating an alliance with them.
  • We Used to Be Friends: With Lincoln, before she considered him a traitor for attempting to save The 100. Him being turned into a Reaver just made things worse, and she refused to allow him anywhere near her even after he was cured. It takes him saving her life and others in Tondc following Mount Weather's attack for her to forgive him.


Played by: Ty Olsson
Character Appearances: Season 2-4 (Recurring Character)

A friend of Lincoln's and a trusted healer among the Grounders.

  • AB Negative: His blood type is Rh-null. note  While it is the future and more people with Rh-null could have been discovered (the Mountain does have a supply of it), Nyko's rare blood is still used for the dramatic will-we-find-a-match trope.
  • Character Death: He gets shot down by drones on Becca's island when the group tries to find a way to cure the Grounders' radiation sickness.
  • Combat Medic: Like Lincoln, he's a good healer and a competent warrior. He seemed to have filled The Medic role for the Grounders after Lincoln joins up with Camp Jaha.
  • Mercy Kill: After he sees that Lincoln has been turned into a Reaper, he attempts to poison him right then and there to put him out of his misery.
  • My Nayme Is: "Nyko," which sounds like "Nico" or a variant thereof.
  • Prisoner Exchange: Octavia takes him hostage and attempts to barter his life for Lincoln's.
  • The Bus Came Back: Reappears at the beginning of Season 4 along with Luna and a Grounder girl, all having been made sick from radiation poisoning.
  • What Happened to the Mouse?: He isn't seen again in the later events of Season 3.


Played by: Jessica Harmon
Character Appearances: Season 3-Present(Recurring Character)

A Grounder who runs a trading post with her father in the Trikru area and has been secretly trading supplies with Clarke during her self-exile.

  • Ascended Extra: While she never becomes a main cast member she does stick around as a recurring character for the rest of the series and becomes a lot more important then just being Clarke's Temporary Love Interest. Not only does she survive the entire series but she even comes back from transcendence with the rest of Clarke's friends so she can keep them company.
  • Conflicting Loyalty: Niylah's loyalty to both Clarke and Octavia gets put to the test in Season 5 after she finds out that Madi is a Nightblood. She decides to Take a Third Option and tells Clarke that she will give her a day to tell Octavia the truth about Madi before she does.
  • Missing Mom: Her mother was one of Mount Weather's victims.
  • Morality Chain: For Octavia in the early episodes of season 6. While Octavia is in the depths of her self-loathing and despair, Niylah is the only one she trusts aboard the mothership. Niylah tries to get her to back down from a fight and she actually does.
  • Morality Pet: She brings out Clarke's softer side toward strangers post- Mount Weather's extermination.
  • Put on a Bus: It is implied that she later leaves her trading post to avoid the A.L.I.E problem. This turns out to only be temporary though as she returns in Season 4 and becomes a recurring character for the rest of the series.
  • Replacement Goldfish: Subverted because she only shares one night with Clarke and after Lexa's death Clarke once again finds herself at her home needing her help but of course Niylah is later Put on a Bus and Clarke is not only grieving but also focused on her task to worry about pursuing a relationship and they never even talk about the night they spent together.
  • Ship Tease: With Octavia. In episode 5x02, there's even a parallel to 3x01 (where Bellamy's girlfriend Gina gives him a book) when Niylah gives Octavia a book, also on Greco-Roman mythology.
  • Temporary Love Interest: She and Clarke enjoy a night together before Clarke's troubles find her again. In Season 4, the two seem to have a more casual romantic relationship.
  • Undying Loyalty:
    • She never even considers betraying Clarke because she's so thankful for the destruction of Mount Weather.
    • After she is spared from Praimfya by Octavia and given a place in the bunker she becomes incredibly loyal to her even after she becomes Blodreina. She also wakes Octavia from cryosleep against all orders in the first episode of season 6.
  • You Killed My Father: Her father was a part of the army Pike and Bellamy massacred and because of this she didn't want to help Clarke and the others when they came to her home trying to hide from A.L.I.E and get her out of Raven's head. She has a confrontation with Bellamy when she overhears Raven talk about his part in the massacre though subverted because she only gets angry with him but does not try to kill him.
    • As stated above Mount Weather is responsible for the death of her Mother and this is why she is kind to Clarke who is responsible for wiping them out.



Commander Lexa
Season 2 Lexa on her throne 
Season 3 Lexa promo 
Known Aliases/Titles: The Commander, Heda, Leksa
Character Appearances: Season 2-3(Recurring Character)
Status: Deceased

"I'm the Commander. No one fights for me."

The Commander of all the Twelve Grounder Clans.

  • The Ace: Lexa is not only an incredibly gifted warrior but also a wise and thoughtful diplomat whom, under her leadership, was able to unite Twelve other Grounder Clans into her coalition. Titus mentions that as Flamekepper he has served 4 previous commanders and not one of them were half as strong or wise as Lexa.
  • Action Girl: As an expert warrior who has lead her people through many wars and earned her leadership through combat.
  • Actually, That's My Assistant: 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.
  • Aggressive Submissive: Downplayed, but it's there. Between her and Clarke, Lexa is the more aggressive warrior, more bloodthirsty and in general is the one pushing more for the relationship, but when they make love, Clarke is the aggressor.
  • Alien Blood: Her blood is pitch black, marking her as a Nightblood.
  • Anti-Hero: As a leader she was willing to make peace with the Sky People and unite their people to take on a common enemy. She is also shown to be ruthless and willing to make some dark decisions such as sacrificing several people in the missile attack and was willing to wipe out the Sky People if they ever became a threat to her people.
  • Asskicking Leads to Leadership: She earned her position, and it's made clear that if she was weak she'd be killed by her own men.
  • The Atoner: In Season 3, she is trying to make it up to Clarke for abandoning her and her people at Mount Weather by trying to make a lasting peace between Grounders and Sky People.
  • Back for the Finale:
    • In "Perverse Instantiation Part 2," she gets a Big Damn Heroes moment helping Clarke through the City of Light.
    • Lexa, or rather her form, appears again in the series final episode The Last War as the form the Judge takes for Clarke since she represents both her greatest love and greatest failure.
  • Badass Longcoat: Part of her usual commander getup, combined with a long red Scarf of Asskicking that trails from her shoulder pad.
  • Beneath the Mask: Despite her Love Is a Weakness facade, she often shows a gentler, softer side.
  • Bolivian Army Ending: Her Last Stand in the City Of Light so that Clarke can get to the kill switch ends like this as it isn't shown whether or not she dies "again" in the fight against A.L.I.E's people.
    • This makes it a possibility that she may be still alive in the Flame/A.L.I.E 2 chip and possibly make an appearance in future seasons if the chip is ever used again.
  • Born-Again Immortality: She states that when she dies, her spirit will choose the next Commander and will be reborn through the A.L.I.E. 2.0 chip implanted in her brain-stem. This is confirmed in the Season 3 finale when she returns and helps Clarke in the City Of Light.
  • Character Death: Accidentally shot by Titus who was trying to shoot Clarke and frame Murphy for Clarke's death.
  • Closet Key: Lexa was the first girl Clarke felt something for on the show and their first kiss revealed to the viewers that Clarke is bisexual.
  • Commanding Coolness: The highest-ranking leader of the Grounders with a rank of "Commander."
  • Cyborg: She is technically one because of the revelation of the A.L.I.E 2 chip being in her head and it being revealed that her black blood is artificial and is used to process information from the chip.
  • Dual Wielding: She does this in ''Watch the Thrones'' after stealing Roan's sword. Given that Anya was her mentor, she may have learned it from her. She also fights with two swords when she helps Clarke in the City Of Light.
  • Easily Forgiven: Averted. Clarke was still angry with her for abandoning them at Mount Weather to the point of wanting to kill her and she only eventually forgave her because Lexa was putting effort into making peace between their people and having to stay by her side to guarantee and maintain the peace. She is later able to forgive her enough for her romantic feelings towards her to come back.
  • Facial Markings: 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 the leader.
  • Fake Guest Star: She got a lot of character development and made about the same amount of appearances as the main cast and she was used to promote the third season.
  • Friend to All Children: Lexa has a soft spot for the children she trains. In "Ye Who Enter Here", Lexa is seen training with one of the Nightbloods, Aden, praising him during their match and backing off when he manages to hit her rather than countering.
  • Heroic Sacrifice: Of a sort in "Perverse Instantiation pt. 2." She's already dead, but her holding off the crowd of Chipped people so Clarke can make it to the killswitch is framed as such.
  • Iconic Sequel Character: While mentioned indirectly in Season 1, Lexa didn't make a proper debut until midway thru Season 2. However, she almost instantly became one of the show's most popular and iconic characters due to the fact that she was seen as great LGBT representation, being a lesbian who was allowed to be more than just their sexuality, and her interesting dynamic with Clarke. She was eventually made Clarke's main love interest and her One True Love, even being brought back years after she died as the form the Judge takes when talking to Clarke.
  • I Did What I Had to Do: Lots and lots of times, the two major ones being 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 abandoning the forces of Camp Jaha after having negotiated the release of the Grounder prisoners from the Mountain Men.
  • Iron Lady: She's renowned even by other Grounders for her ruthlessness.
  • Kneel Before Frodo: After originally saying she wanted Clarke to bow before her in "Ye Who Enter Here", she kneels before Clarke and swears loyalty to her.
  • Lady of War: She's her people's leader, is always 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.
  • Living Emotional Crutch: Alycia Debnam-Carey stated here that Clarke finds solace with Lexa and vice-versa.
  • The Lost Lenore: Lexa is not the only person Clarke loved and lost, but she is by far the one Clarke mourns the most. Lexa's death still haunts Clarke years later.
  • Love-Interest Traitor: Played with. 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. Season 3 makes it ridiculously clear she regrets it though, especially when she sees what it did to Clarke.
  • Love Is a Weakness: 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.
    • Overtime Lexa eventually subverts this trope due to her love for Clarke and in Season 5 Madi tells Clarke that Lexa is the only one of the Commanders who doesn't believe this anymore.
  • My God, What Have I Done?: Lexa has this moment in "Ye Who Enter Here" when Clarke holds a knife to her throat in revenge for abandoning the Sky People on Mount Weather and for forcing Clarke to irradiate the mountain. While Clarke can't bring herself to kill Lexa the experience rattles Lexa and she notes that she never wanted Clarke to turn out like that. She almost allows Clarke to leave the capital without becoming part of her coalition before Clarke stops her.
  • My Greatest Failure: As Madi reveals to Clarke near the end of Season 5 Lexa views her decision to abandon Clarke to face Mount Weather alone to be the greatest regret of her life. She therefore shows Madi these visions to convince Clarke not to make the same mistake she did by betraying her friends to protect Madi. This drives Clarke to tears and finally lets her accept Madi becoming Commander of Wonkru.
  • Never Be Hurt Again: 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. Then she meets Clarke.
  • Not Quite Dead: Her body dies but her mind is uploaded into the Flame/A.L.I.E 2 chip.
  • Not So Stoic: Whenever Clarke's around, Lexa drops her guard and is more open.
  • One True Love: Lexa ends up becoming this for Clarke. While neither of them are the first people each other has loved their bond is stronger then any they've ever had and Clarke never fully moves on after Lexa dies to the point that she never has another love interest for the rest of the series. To fully cement this in the series finale the Judge takes on the form of Clarke's greatest love who is shown to be Lexa with Word of God confirming that this was an intentional choice to show how important Lexa was to Clarke.
  • Ooh, Me Accent's Slipping: Lexa is "more than cuypable of separating feelings from duty!".
  • Put on a Bus: In Season 2, when she abandons Clarke and the rest of the Sky People in the first episode of the two part season finale.
    • In Season 3, her death could be considered this because of her mind being uploaded into the A.L.I.E 2/The Flame chip and The Bus Came Back when she returns to help Clarke in the City Of Light in the finale.
  • Reasonable Authority Figure:
    • 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 Reapers back to normal they are willing to enter a truce so long as 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.
  • Rule of Symbolism: In Episode 3 of Season 3, Lexa bows before Clarke and swears fealty to her, but the way she says it, their by that point confirmed attraction and the overall look of the scene makes it look a lot like a marriage proposal. Considering what happens 4 episodes later...
  • Sacrificial Lion:Her death serves the purpose of furthering the A.L.I.E plot with the revelation of the A.L.I.E 2 chip which is later revealed to be the way to defeat A.L.I.E being inside her head and that a nightblood becomes the new commander when it is put in their head leading to the search for Luna to prevent the sociopathic Ontari from becoming commander. The search for Luna results in Clarke returning to Arkadia to find Lincoln to get information on how to find her but instead returns to find out that he is dead and that Arkadia has been taken over by A.L.I.E putting her in to the plot.
  • Second Love: For Clarke.
  • Secret Test of Character: 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.
    • Giving Clarke the choice on whether or not to kill Emerson is implied to be one as she gives the implication that she may declare war on Clarke's people if she decided to kill him as she would have been shown to be a hypocrite for wanting to kill him for what he did to her people, but expects Lexa not to punish the Sky People for what Pike and the others did to her people.
  • Sergeant Rock: She cannot show weakness to anyone, not even her men. But she does care for them dearly.
  • Sex Equals Love: The series has plenty of love scenes, but the one between Lexa and Clarke stands out as by far the most romantic up to that point.
  • Ship Tease: With Clarke in Season 2 when it is revealed that Lexa is attracted to women because of her story about Costia and she is shown to really care about Clarke. Becomes less of a tease when Clarke reveals the feeling is mutual when they kiss but declines to enter in a relationship with her for now because of what recently happened to Finn and wanting to focus on getting her people out of Mount Weather.
  • The Stoic: Hardly shows any emotion. A notable exception is when she's forced to kill her bodyguard; she looks visibly shaken afterwards.
  • Story-Breaker Power:The revelation of the A.L.I.E 2 chip being in her head and the events of the finale makes it clear that if Lexa hadn't died she could have defeated A.L.I.E way before she was able to recruit so many people if she ever found out about what she was doing.
  • Sugar-and-Ice Personality: She's a ruthless and stoic commander. But when she's around Clarke she's more open and vulnerable.
  • Supporting Leader: The highest-ranking member of the grounders, she commands the military forces. She united a coalition of twelve different clans under her banner.
  • Tough Leader Façade: Implied to be this; she notably became more closed-off and ruthless after Costia's death so she could better lead her people.
  • When She Smiles: In the few instances that Lexa actually smiles, it is truly something endearing.
  • Wrong Genre Savvy: She expects Clarke to be able to forgive her betrayal with them being the two stars of a Darker and Edgier Crapsack World story full of Black-and-Grey Morality. Instead, the next time they meet Clarke spits in her face and screams that she's going to kill her. Subverted. While Clarke may or may not have forgiven, she does agree to enter into an alliance with her in "Ye Who Enter Here".
    • This is zig-zagged with her decision to make the Sky People the 13th clan and also her later decision to not retaliate against the Sky People for Pike's actions as she is aware that her people will have a problem with her decisions and that some may attempt to kill her and take her throne which Queen Nia attempted to do. She later comes up with a middle ground on the Pike situation by giving the Sky People the choice to either surrender him to them or be confined in a border that if they ever cross they will be killed on sight as she didn't want to wipe them out but she couldn't let them get away with the things they've done either, but of course this wasn't enough for some of her people and this eventually leads to an attempted assassination by one of her people and later leads to her accidental death by Titus.
  • Young and in Charge: She's obviously far younger than a lot of the Grounder warriors she commands. She is actually around age 20-22 and became commander when she was 12.
    Abby: (on the Grounders) They're led by a child!


Played by: Dichen Lachman
Character Appearances: Season 1-2(Recurring Character)
Status: Deceased

An authority figure for The Grounders. She meets with Clarke to discuss a peace treaty.

  • Action Girl: A leader who can hold her own in a battle and even trained the Commander herself.
  • Badass Boast: 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.
  • Badass Longcoat: 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 some inspiration in her formal getup.
  • Character Death: She gets shot by members of the Camp Jaha right after parting with Clarke after agreeing to try and work towards peace.
  • Demoted to Dragon: When Tristan shows up and reveals the Grounder Commander put him in charge, she steps down.
  • Dual Wielding: She dual-wields two long blades in the first season finale.
  • Enemy Mine: She and Clarke have to work together to escape Mount Weather.
  • The Leader: Subverted. Her group's only part of a larger faction, although she does have the authority to call for a truce.
  • The Mentor: Was previously one to Lexa.
  • Moral Myopia: Everything she complains to Clarke as being an act of war was retaliatory, especially the trespassing onto tribal land as that was a direct result of Lincoln kidnapping Octavia. What's worse, she brings a Child Soldier as part of the force intending to exterminate the 100, and when that attack is repelled, kidnaps Clarke, takes a hostage and forces Clarke to provide medical aid to said child. Then after killing the child herself because the treatment wasn't as effective as she'd like, she tries to kill Clarke and the hostage. It's so bad, Lincoln helps Clarke escape and goes Screw This, I'm Outta Here, explicitly telling Clarke that his tribe is wrong.
  • Occupiers Out of Our Country: 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.
  • "Shaggy Dog" Story: 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 is shot by Camp Jaha guards.
  • Shadow Archetype: 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 Peace Conference, but she has a much harsher attitude than Clarke and seems much less inclined to believe that peace is actually possible. Justified in that Clarke was raised by loving parents who taught her to value others' lives, while Anya was raised an a hostile Death World where aggression and territorial paranoia are the only things that keep you alive. The fact that Clarke basically told Anya to behave or else because other Skypeople are coming , ends up justifying Anya's distrust of the Skypeople.
  • Ungrateful Bitch: 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.
  • Villain Has a Point: 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.
  • What the Hell, Hero?: 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.)
  • Worst Aid: 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: Aleks Paunovic

"If you so much as look at her the wrong way I will slit your throat."

A high-ranking member of the Grounders and part of Lexa's inner circle.

  • Bodyguarding a Badass: He serves as Lexa's bodyguard, although she hardly needs one.
  • Death of a Thousand Cuts: His fate after he admits to framing Raven for trying to poison Lexa.
  • My Nayme Is: "Gustus," a shortened form of "Augustus." Who had a sister named Octavia...
  • Shadow Archetype: 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 admits later that it just "made sense" to him.
  • Tampering with Food and Drink: Slips poison into his cup in order to pretend it was an attempt on Lexa's life.
  • Undying Loyalty: To Lexa. Everything he did was to try and keep her safe.


Played by: Neil Sandilands

The current Flamekeeper (Fleimkepa), his role is to give the Commander counsel. Titus is against allying with Skaikru, believing that it will endanger the alliance.

  • Accidental Murder: He had been meaning to kill Clarke, but accidentally shoots Lexa instead, causing her death.
  • Can't Kill You, Still Need You: He is not punished for what happened to Lexa because of him being the only flamekeeper.
  • Expy: In-Universe; He is basically an older version of Gustus who was also against Lexa making peace with the Sky People out of the fear that this decision would make it that their people will turn against her and try to kill her. They also both attempt to frame a Sky Person for an assassination to manipulate Lexa into wiping them out and they both seem to see Lexa as a daughter.
  • Never My Fault: He initially blames Clarke for his accidental murder of Lexa since she was the one he was trying to kill and the fact that he tried to because of her convincing Lexa not to declare war on the Sky People for what they did.
    "You killed her. I pulled the trigger, but it was you."—Titus to Clarke
  • Redemption Equals Death:He tells Clarke about Luna and gives her the Flame and he also kills himself on Roan's knife so Ontari can't use him as a flame keeper all to redeem himself for accidentally killing Lexa.
  • Slashed Throat: How he dies; he moves while Roan holds a knife up to his throat.
  • Treacherous Advisor: Subverted. Although he opposes Lexa's actions, he has the best interests of Trikru at heart. It's mentioned that he was the Flamekeeper for the three previous commanders as well.
  • Undying Loyalty: He is loyal to Lexa despite the fact he doesn't agree with her decisions when it comes to Clarke and Skaikru. His loyalty to her is why he honors her last request to never again attempt to harm Clarke.
  • Well-Intentioned Extremist: He believed that Clarke's presence in Polis was weakening Lexa's position and thus the safety of his Commander and people. His solution? Attempt to kill her!


" I'm the man sent to slaughter your people."
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.

  • Big Bad: Serves as this in the Ground storyline of Season 1, considering he is the one leading the assault on the 100. Turns out to be a Disc-One Final Boss when Season 2 rolls around, with him being killed early in Season 2.
  • Boom, Headshot!: He ends up meeting his end this way thanks to Kane.
  • Disc-One Final Boss: 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.
  • The Stoic: Shows little to no actual emotion.


Played by: Cameron Roberts

Member of the Woods Clan who served under Indra and helped Octavia when she was trying to save Lincoln from the Reapers. He is the second and most notable victim of Finn's massacre.

  • Character Death: Shot by Finn when he attempted to attack Finn for killing one of his fellow villagers.
  • Revenge Before Reason: As stated his death is a result of his attempt to attack Finn who had a gun while he didn't have any weapons rushing towards him in a blind rage as a result of the first person he shot who attempted to escape, even before this he was anxious to try and sneak attack him but Nyko held him back to try and prevent him from getting killed.
  • Sacrificial Lamb: He is the only victim of Finn's massacre who has gotten any screen time and it is shown that Nyko and Octavia were really saddened by his death and his death really showed that Finn has gone too far.

The Ice Nation (Azgeda)
Symbol Of The Ice Nation

The Azgeda, or Ice Nation, is a Grounder clan led by Queen Nia. The Trigedakru and Azgeda were at war with each other before the creation of the Coalition. Lexa tells Clarke how the Queen of the Ice Nation killed her former lover, Costia, because she believed that Costia knew all of Lexa's secrets. In retaliation, Lexa banished Prince Roan as part of the conditions of allowing the Ice Nation into the Coalition. The Ice Nation stretches for thousands of miles. The Ice Nation border is at Sector 8, but the ice is farther to the north. Many Azgeda have distinctive facial scarring and many of the Ice Nation warriors are known to wear white paint.

     The Ice Nation As A Whole 

  • Arch-Enemy: They are this to the Trikru and Lexa as many years ago they were at war with them until the formation of the Coalition, but they still show animosity towards the Trikru and other clans. When the relationship between the two clans deteriorates due to the presence of the bunker Indra even notes to Roan that a war between their two peoples was a long time coming.
  • Big Bad Wannabe: In the first episodes of Season 3 they were setting up to the be the big threat when they are hunting Clarke and eventually one of their warriors blows up Mount Weather with several residents of the Sky People living there. Their threat is diminished when their queen is killed by Lexa and replaced by her son, Roan who makes peace with Lexa.
  • Early-Bird Cameo: In Season 2, they have representatives as part of the war council to take on Mount Weather and Lexa also talks about Queen Nia and how she was responsible for her first love's death and being in war with them many years ago.
  • Filler Villain: They are only the antagonists for the first 3 episodes of Season 3 and their actions only set up Pike as the true Arc Villain of the season until A.L.I.E takes over as the true Big Bad.
  • The Friend Nobody Likes: Azgeda is a member of Lexa's coalition and, as such, they are technically meant to be allies with the other clans. However due to their bitter relationship with Trikru and their brutality nobody in the coalition really trusts them.




Queen Nia
Played by: Brenda Strong

The leader of the Ice Nation, Nia resents being forced to bow to Lexa and is rumored to be preparing to move against her.

  • Arch-Enemy: She was this to Lexa because of the fact she was responsible for the torture and death of Lexa's first love Costia and she later attempts to take Lexa's throne.
  • Big Bad Wannabe: Considering she had almost an entire season of buildup, the Ice Queen was killed off pretty quickly, spending less than an episode's time alive on-screen.
  • The Ghost: Frequently mentioned, but goes unseen until the very end of "Ye Who Enter Here".
  • God Save Us from the Queen!: Given her reputation, Nia appears to be ruthless and brutal even by Grounder standards.
  • Impaled with Extreme Prejudice: Courtesy of Lexa who throws a spear into her chest while Queen Nia is yelling at his son to not die a coward..
  • Small Role, Big Impact: Despite dying only an episode after being introduced her actions in blowing up Mount Weather leads to Pike taking over as The Chancellor for the Sky People and almost restarting the war between Grounders and Sky People as well as Lexa's death and arguably making A.L.I.E.'s plans run much smoother.
  • Surprisingly Sudden Death: When it looks like Lexa will kill Roan after he's been beaten at the Conclave, Lexa instead throws her spear at Queen Nia on the sidelines, killing her.
  • We Hardly Knew Ye: Killed by Lexa in the episode following her introduction at the end of the other.
  • Xanatos Gambit: Her actions involving the destruction of Mount Weather was all to achieve her main goal of taking Lexa's throne, this includes having Echo lure Bellamy and others away and making them think that they are going to attempt to kill Lexa knowing that Sky People interupting the ceremony would sway votes to her side or that they might accidentally kill Lexa themselves in the confusion. Her plan in the end only failed because of the Sky People officially becoming the 13th clan making it that Clarke's vote counted as well.


Played by: Rhiannon Fish
Character Appearances: Season 3(Recurring Character)
Status: Deceased

A Nightblood from the Ice Nation, raised by Nia to become the next commander after Lexa.

  • Alien Blood: Her blood is pitch black, marking her as the next best thing to Grounder Royalty.
  • Big Bad Wannabe: Considering the fact that she murders the other Nightblood children and takes the Commander position for herself after Lexa's death one would assume she would be the Big Bad for the rest of the season. Unfortunately for her, by the time she puts her gambit into motion, the season has already been dominated by a rogue A.I. who eventually takes over her mind and turns her into a Puppet King and by the end of the season she ends up dead.
  • Character Death: Under A.L.I.E's control she is bashed in the head by Jaha and is rendered brain dead. Her body later dies after Abby cuts open her chest and has Murphy manually pump her heart in order to keep the blood flowing into Clarke.
  • The Dragon: By all appearances, she is Nia’s second in command.
  • Dragon Ascendant: Becomes the new threat after Lexa's and Nia's deaths and making a play for the throne.
  • Evil Counterpart: To Lexa as they both have similar backgrounds because of being Nightblood's but Ontari is shown to be a lot more ruthless than Lexa when she kills all of the Nightblood children in their sleep and shows everyone their heads. She is also sadistic which is shown by the way she treats Murphy and also appears to be a sociopath because of the way Nia raised her and being emotionally unstable.
  • Facial Markings/ Covered with Scars: She has many scars on her face in the shape of tribal symbols cut into her skin.
  • Fake King: She was not the official commander because of not having the Flame and was pretending to have it and have gone through the ceremony so that she can rule as the commander until Roan finds it and makes her official.
  • Hidden Depths: In her interactions with Murphy she reveals that the Ice Queen stole her from her parents and that she was cruel to her growing up. She is also shown to be insecure and filled with self-doubt about her new position as commander even shown rehearsing to make herself sound more like a commander.
  • The Nose Knows: She is able to smell the poison on Clarke's sleeve from across the room preventing her from poisoning Nia.
  • Klingon Promotion: After Lexa's death, she ensures that she becomes the new commander by murdering her competition in their sleep. A deconstruction as Titus and possibly other Grounders found what she did dishonorable as the decision was supposed to be decided in a fight to the death and her action leads to Titus giving the Flame to Clarke so that she could make Luna commander instead of her.
  • Living Macguffin: She becomes one when Clarke is forced to seek her out and try to put the Flame in her after Luna says no. Clarke is later forced to use her brain dead body to pump nightblood into herself so she can use the Flame herself.
  • Out of Focus: In her first appearance she is mostly only seen by Nia's side. After Nia's death, she is not seen for a few episodes until after the death of Lexa which results in her making a play for the throne of commander. During her turn as a fake commander she get some character development but after getting taken over by A.L.I.E she only appears in the background and gets killed off in the finale.
  • Puppet King: Nia makes it clear that she intends to rule the coalition through her. Subverted with Roan who becomes king after Nia's death as Ontari only obeys him because of this but she states to him that once she becomes commander he will have to obey her and after becoming a fake commander she orders him to find Clarke when she runs off with the Flame.
    • She later becomes this for A.L.I.E after Jaha convinces her to take the chip and A.L.I.E uses Ontari's position as commander to chip almost all the grounders in Polis.
  • Royal Blood: She is a Nightblood, meaning that she is eligible to become the next Commander.
  • The Sociopath: She shows no remorse for what she did to the nightblood children and was going to kill the advisors who questioned her legitimacy of being the commander before Murphy talked her out of it and it shown that she has a hard time keeping her emotions in check and could snap at any second.
    "Ontari's crazy and that's coming from me"—Murphy
  • Tyrant Takes the Helm: After Lexa's death and Ontari's massacre of the remaining Nightblood children she takes over as the new Commander of the Twelve Clans. Unfortunately for Ontari her rein doesn't last long.
  • Villainous Crush: She takes a liking to Murphy when he doesn't show her any fear and Murphy exploits this to become the new flamekeeper and guarantee his survival a little longer but he also ends up becoming her sex slave when she gives the implication that she will kill him if he doesn't sleep with her and if he ever displeases her.
  • Would Hurt a Child: She murdered all the children who were groomed to be Lexa's successor.

The Boat People (Floukru)
Symbol Of The Boat People

The Floukru, also known as Floudon Kru or the Boat People, are a clan led by Luna. This clan is allied with the Trikru and, according to Lincoln they live "east to the sea, then across it . The Floukru's territory is east of the Trikru's territory. The Floukru have functioning diving suits and boats. They live on an oil rig, away from the mainland. This allows them to live in peace, avoiding violence and war. They take in orphans, people fleeing wars, and those done fighting and killing. Their peaceful philosophy makes them different from the other clans. Their spiritual views differ slightly from other Grounders. Instead of burning their dead, they return the bodies to the sea. While other Grounders use the phrase "Yu gonplei ste odon" ("Your fight is over"), Floukru uses the phrase "Kom woda ‘so gyon op, gon woda ‘so kom daun" ("From water we are born, to water we return") as the last rites.

    The Boat People As A Whole 

  • Back for the Dead: The Boat People make a return apperence in Season 4 suffering the effects of advance radiation poison. By the end of the episode all but Luna end up dead.
  • Badass Pacifist: Besides Luna, other members are implied to have combat experience and the ones who travel to the mainland to gather supplies and pick up people who want to join the clan are shown to be stealthy and they also carry weapons.
  • Everybody's Dead, Dave: The Floukru, besides Luna, all end up meeting their untimely ends in "The Four Hoursman" due to the radiation exposure caused by the fish they eat.
    • Luna later dies in the conclave, so the entire clan is now dead.
  • Perfect Pacifist People: Luna's clan lives in peace and they avoid violence and war . They also take in other grounders who are done with fighting, which also includes orphans and some fleeing from war.


Played By: Nadia Hilker

Leader of the clan east of the sea. She is also a Nightblood and is originally from Polis where she and Lexa grew up and trained together for the Conclave to choose the next commander.

  • Alien Blood: As a Nightblood her blood will be black. Not that we see her bleed. As it turns out it's this very blood the makes her immune to radiation sickness.
  • Always Someone Better: She implies she was a better fighter than Lexa and that if they fought in the conclave she would have beaten her and this is why she fled because she didn't want to kill her or anyone else.
  • Badass Boast: "I didn't flee the conclave because I was afraid I would lose, I fled because I knew I would win."
  • Badass Pacifist: She leads the Floukru for those done with fighting. Currently, she lives a life of non-violence with her people and doesn't agree with the Grounder code of "Blood Must Have Blood", but is shown to be very skilled in combat with her take down of Clarke when she tries to force the Flame into her head.
    • She also doubles as a Martial Pacifist because of her skills in combat and being good with children. This eventually leads to her being forced to break her code of not killing when she kills A.L.I.E's followers when they try to force her to take the chip by threatening a child.
    • Also an Obstructionist Pacifist because of her vow against violence and her later decision to drug Clarke and the others and return them to the mainland kept them from defeating A.L.I.E sooner since Luna's skills and her getting the kill code from the Flame could have made it easier and would have prevented them from having to try and rescue Ontari which eventually lead to Clarke having to use her blood to use the Flame and defeat A.L.I.E herself and having a harder time because of this.
  • The Bus Came Back: She and the rest of The Floukru return in "The Four Horseman" suffering from radiation poisoning and asking to be saved by the Sky People. Sadly only Luna survives the rest end up dead.
  • Character Death: Octavia takes her out by way of a sneak attack in the Conclave.
  • Childhood Friends: It is implied that she and Lexa were this by the fact they grew up and trained together. Luna didn't want to kill Lexa after having to kill her brother and left the conclave and the Trikru to avoid doing it.
  • Early-Bird Cameo: Was mentioned in Season 1 before her introduction in Season 3. She was noted to be a friend of Lincoln's who would take him and Octavia in and he was originally going to bring all of the 100 to her clan when the conflict with the Trikru got worse.
  • Face–Heel Turn: At the final Conclave, Luna declares that if she wins, no one will be allowed to stay in the bunker and all of humanity will simply die when the death wave approaches.
  • Friend to All Children: Much like Lexa, she has a soft spot for children, and abandoned her pacifist code of conduct to protect a young girl that was being threatened.
    • When she reappears in Season 4 she desperately asks Skaikru to help save her people and especially a little girl slowly dying from radiation poisoning. When that fails to work she tenderly holds the child as it dies.
  • Freudian Excuse: It is implied that she doesn't like violence and killing because of when she had to kill her brother in the Conclave.
  • Humans Are Bastards: Having seen the death and destruction caused by her own people during her Conclave Luna strongly believes that most humans are inherently blood thirsty monsters which is why she abandoned her potential coronation as Commander and became the leader of Floukru.
  • The Immune: It's revealed in "The Four Horseman" that her Nightblood allows her to survive the radiation that killed her people possibly making her the key needed to save people from radiation.
  • It's All My Fault: Luna asks Clarke when she returns in Season 4 if watching all of her people slowly die off right in front of her is punishment for not accepting The Flame in the previous season.
  • Killthe Ones You Love: Forced to kill her brother in the conclave. Forced to kill her implied to be lover Derrick after he's chipped by A.L.I.E.
  • One-Shot Character: In Season 3, she is only shown at the end of one episode and is a major character in the next, without making anymore appearances in the later episodes. She has a recurring role in Season 4.
  • Prongs of Poseidon: Her main weapon of choice is a trident, fitting for a member of the Boat People.
  • Refusal of the Call: Knew she could have become the next commander, but refused and fled the conclave. Even after seeing how dangerous A.L.I.E is she still refuses to take the Flame and drugs and banishes Clarke and her friends off the oil rig.
  • The So-Called Coward: She is considered a coward by Titus and Grounder society because she ran away from the conclave when she was supposed to fight Lexa in the last round, but she states that she didn't run away because she thought she would lose, but because she knew she would win and that she didn't want to fight and kill anymore after having too kill her brother in her first fight.
  • Sole Survivor: She and the rest of her people go to the Sky People after suffering extreme radiation poisoning. However Luna is the only one to survive due to her Nightblood thus leaving her as the sole surviving member of the Floukru.
  • The Stoic: Just like other Grounder characters she doesn't show very many emotions and only seems slightly saddened when she finds out about the deaths of Lincoln and Lexa.
    • Not So Stoic when she is forced to kill Derrick who was under A.L.I.E's control in self defense and she cries over his death, but she goes back to stoic later on and almost shows no emotion when Clarke and the others collapse from their drinks being spiked by her, so that she can send them back to mainland.
  • Straw Nihilist: She becomes this in Season 4 after years of witnessing both the brutality of Grounder culture and the extreme lengths Skaikru is willing to go in order to save humanity. As the last of the Floukru, she has no one left to fight for and fights only for death, declaring that humanity should just die from the radiation.
  • Stronger Than They Look: Luna outright states that if she hadn't fled the Conclave, she would have defeated Lexa and become the next Commander. Based on appearance alone, she's a peaceful and serene individual and states that she hates fighting and killing now. When we see her fight at the Conclave in Season 4, she's a ruthless combatant and she's able to hold her own against both Roan and Octavia at the same time.
  • There Is Another: After Ontari has all the other nightbloods killed, thus ensuring that she is the only possible candidate for becoming the next commander, Titus reveals that Lincoln's mysterious friend Luna is a Nightblood who fled the conclave long ago.
  • Thou Shalt Not Kill: She has vowed never to kill again after fleeing the Conclave. Subverted when she is forced to kill A.L.I.E's followers when they threaten a child. Her vow against killing is why she refuses to become the new commander and help in the fight against A.L.I.E because she knows that the fight might require her to kill people.
  • Woobie, Destroyer of Worlds: She becomes one after witnessing the deaths of her entire clan and being perceived as a tool by Skaikru simply for having Nightblood.
  • Worf Had the Flu: Luna loses a fight to Roan in Becca's lab after refusing to take part in any more of their experiments. When the two meet again at the final Conclave, she outright states that the only reason Roan won their last fight was because she was injured at the time and weak from having her bone marrow extracted. She wasn't wrong, as she takes on Roan and Octavia at the same time on equal footing. The Back Rain forces Octavia to run, but Roan can't get away from Luna before she drowns him.


Played By: Nesta Cooper
Member of the Boat People who is a storyteller that gets close to Jasper.
  • Actual Pacifist: As a member of Luna's clan she never does anything violent even in self defense and it is never shown whether or not she had any fighting skills from being a Grounder, but it can be assumed she didn't as it is stated that she was apart of the clan her whole life and because of this didn't go through the training most Grounders go through in their childhood.
  • Dying Moment of Awesome: She is able to unlock the freighter to let Clark and the others out before dying from her arrow wound.
  • Sacrificial Lamb: She is just another victim of A.L.I.E that shows how far A.L.I.E is willing to go to accomplish her goal and it is implied that her death is part of the reason why Jasper ends up taking the chip.
  • Ship Tease: Gets somewhat close to Jasper, with whom she shares stories. Bellamy notes that it's the first time he's seen Jasper smile in months. Ended though, with her death.
  • Suspiciously Similar Substitute: For Maya, being The Cutie and a potential love interest for Jasper (so she may also count as a Replacement Goldfish). Like Maya, she ends up tragically dying.
  • Too Good for This Sinful Earth: She was a member of a pacifist clan, a storyteller, and a kind person only to end up getting killed by A.L.I.E's people.
  • We Hardly Knew Ye: Killed by an arrow in the back in the episode she was introduced.


Played By: George Tchortov

Member of the Boat People, who is implied to be Luna's lover and her second-in-command.

  • Brainwashed and Crazy: Taken over by A.L.I.E when he takes the chip to stop Luna's torture.
  • Character Death: Luna kills him in self defense when he tries to kill her under the control of A.L.I.E.
  • "I Know You Are in There Somewhere" Fight: Luna tries to get him to snap out of A.L.I.E's control until being forced to kill him.
  • Satellite Character: He is only shown in interaction with Luna and as stated he might have been her lover.
  • Stupid Sacrifice: He takes A.L.I.E's chip in an attempt to get her followers to stop torturing Luna but after he takes it he falls under A.L.I.E's control he takes over in the torture.

     Sea Captain 

Sea Captain
Played By: Tristan Jensen

Member of the Boat People, who comes to the mainland with other members to pick up Clarke and the others and he is also one of the guards that gets taken over by A.L.I.E.

Nomadic Grounders

Nomadic Grounders, also known as Wastelanders, are Grounders who have no clan because they or a family member may have been seen as a "stain on the bloodline" due to birth defects and cast out. So far, they seem to inhabit The Dead Zone with some of them on their way to the City of Light in search of safe haven.

     Nomads As A Whole 
  • Fantastic Racism: Nomads are banished to the wastelands for their deformities along with family members who refused to kill them the moment they were born.
  • Mutant: Most Nomads have a deformity because of the left over radiation giving them birth defects.



Played By: Luvia Peterson
Sienne is a Nomadic Grounder living in the Dead Zone with her husband, Osias, and her son, Zoran.
  • All for Nothing: The City Of Light turning out to be virtual means that her and her family will never reach their destination.
  • I Did What I Had to Do: Turns in Jaha to the grounders for a bounty on all Sky People for a horse so she and her family could travel to the City Of Light.
  • Mama Bear: She is shown to be very protective of her son and protecting her son is why she is a Nomad because she refused to kill him/allow him to be killed for his deformity.
  • Small Role, Big Impact: Jaha's interaction with her and her family leads to him going on the journey to find the City Of Light and finding A.L.I.E instead as he found out about the place because it was the family's goal to find it.
  • One-Shot Character: She and her family only appear in one episode in Season 2.


Played By: Finn Wolfhard
Son of Sienne and Osias who was born with a birth deformity on his face, and because of this he was supposed to be cast out of his clan and left to die in order to remove the "stain" from the bloodline. However, his mother loved him too much and left her home with him in hope that he may live.
  • Fantastic Racism: He was cast out because of his deformity.
  • Mutant: Born with a face deformity because of the radiation on Earth.
  • One-Shot Character: Him and his family only appear in one episode in Season 2.



Played By: Chad Riley
Husband of Sienne and Father of Zoran.

Glowing Forest (Trishanakru)
Symbol of the Glowing Forest

The people of the Glowing Forest, also known as Trishanakru, are a clan of Grounders that live in the forest filled with glowing flora and fauna, which was encountered by Clarke and Octavia in the first season. Not much is known about them, but the majority of them appear to be farmers. Many of them have dots tattooed on their foreheads.


Played By: Chai Hansen

Character Appearances: Season 4 (Recurring)
A member of the Glowing Forest clan who lived on a farm with his family. At some point, he came under the influence of A.L.I.E., but he was freed when Clarke disables the City of Light.
  • Cruel and Unusual Death: At the final Conclave, Echo mortally wounds him by shooting his neck with an arrow. He asks Octavia to kill him afterward with her blade.
  • Facial Markings: His facial tattoos are a row of eight dots running down his forehead.
  • Mercy Kill: He does this to his mother when she is slowly dying. Ilian ends up dying in a very similar way later.
  • My God, What Have I Done?: Under the influence of A.L.I.E., he kills both his father and brother and is about to kill his mother before he was freed from the City of Light.
  • New Technology Is Evil: Ilian definitely feels this way due to his entire family dying directly as a result of A.L.I.E. When he arrives at Arkadia, he sabotages one of their server rooms.
  • Sex for Solace: He sleeps with Octavia as the two shelter in a cave from the black rain. Mainly she does it in order to "feel something else".
  • Temporary Love Interest: For Octavia in Season 4.

Shallow Valley (Louwoda Kliron Kru)

The people of the Shallow Valley.


Madi Griffin

Played by: Imogen Tear (Season 4), Lola Flanery (Season 5 onwards)

A member of the Shallow Valley clan. Over the Time Skip at the end of Season 4, Clarke found and adopted her.

  • A Child Shall Lead Them: She becomes Heda after taking the Flame, making her the symbolic leader of Wonkru.
  • Happily Adopted: She loves Clarke to death.
  • I Just Want to Be Normal: Madi's never really had a chance to be a normal kid. She had to forgo sports out of fear others would find out she's a Nightblood, then the Primfaya wave killed everyone she knew and Clarke was her sole companion for six years, and eventually she has to become the Commander to save Wonkru. After the Flame is destroyed, Madi isn't sure what to do with herself, but Jackson tells her that it's okay to just act like a kid for once and play around with people her own age.
  • Last of His Kind: She's the last natural-born Nightblood on Earth.
  • Little Miss Badass: She's fairly young (either a preteen or a young teenager) and is introduced to Bellamy and company when she gets the drop on Eligius mooks and disposes of them easily.
  • Living Emotional Crutch: To Clarke, who loses it if she's in danger. Justified — Madi was her only companion on a barren Earth for nearly six years.
  • Parents in Distress: Is more than willing to murder scores of enemies to get her adoptive mommy back.
  • Plucky Girl: She's surprisingly well-adjusted and takes everything that happens like a champ. Before we meet her, she was forced to hide under the floor to avoid being found out as a Nightblood, saw everyone she ever knew die of radiation poisoning, and then survived two months alone after Praimfaya before being found by Clarke. This doesn't even cover the traumas we see her endure on the show. The only thing that she doesn't handle like this is when she thinks Clarke is dead.
    • However, even she has her limits; when faced with the prospect of acting as Commander without the Flame to call upon, she has a panic attack and runs off. Though in a rare aversion of There Are No Therapists, Madi starts having sessions with Jackson to come to terms with everything.
  • Roaring Rampage of Revenge: Seems to be going on this after Clarke's apparent death to avenge her, especially thanks to Sheidheda's influence.

Desert Clan (Sangedakru)



Played by: Xavier De Guzman

A dissenter against Indra's leadership following the destruction of The Flame.

  • Defeat Means Respect: Deliberately invoked by Indra after Knight openly challenges her leadership, gets his ass handed to him, then given an important mission instead of a punishment. Time will tell if it worked.
  • Jerkass: His time on screen is devoted exclusively to speaking up against Indra at the time of his introduction.
  • Jerkass Has a Point: Technically, he is correct about Indra deceiving Wonkru and the people of Sanctum.


Malachi kom Sangedakru, aka: Sheidheda

Played by: Dakota Daulby, Lola Flanery (while possessing Madi), JR Bourne (while possessing Russell Lightbourne's body)
Status: Deceased

One of the past Commanders, given the title Sheidheda because of his evil and the dark history of his reign. Although he has been long dead, his mind remains in the Flame, and has been using it to convince Commanders to be just like him. He was the Commander during Indra's childhood.

  • Arch-Enemy: Is this for Indra because during his original lifetime he conquered Trikru, killed her father, forced her mother to kneel before him and butchered everyone who didn't.
  • Big Bad Ensemble: One of the main antagonists in Season 7 along with Bill Cadogan, but the two have different goals and are not working together.
  • The Chessmaster: He spends his time on screen in a jail cell. Doesn't stop him from pulling many, many strings in Sanctum.
  • The Corruptor: With every new Commander, Sheidheda apparently always tries to corrupt them into murdering psychopaths and monsters just like him. He spends all of Season 6 trying to do this to Madi and almost succeeds before she is able to resist him at the last moment.
  • Deader than Dead: How he meets his final end after he is blasted by an Elegius sonic cannon. Let's just say that if the show was rated R then this trope would be Ludicrous Gibs instead.
  • Demonic Possession: In a similar sense to how the Primes inhabit the bodies of hosts, Sheidheda takes possession of Madi. At least until she takes back control. Sheidheda manages to transfer to Russell Lightbourne's mind drive, and he quickly kills him to become the body's sole occupant.
  • The Dog Bites Back: Sheidheda was killed by his own Flamekeeper. Why? Because Sheidheda killed the three Flamekeepers before him.
    • His version of the events imply the first Flamekeeper had it coming, but that doesn't account for the following ones.
  • The Dreaded: Sheidheda's infamous brutality made him a figure of terror during his lifetime and after his death he become a Satanic like figure whose presence haunts the Flame. The very real threat that he may take over Madi and control Wonkru is terrifying enough that the heroes are willing to destroy the Flame rather then see him return.
  • Eye Scream: Courtesy of Madi, although it doesn't slow him down at all.
  • Fantastic Racism: Appears to have a low opinion of frikdreina (mutants) if the open disgust he shows Emori and her deformity is any indication.
  • Final Boss: Since Bill Cadogen dies early in the finale Sheidheda becomes the final antagonist of not just the series but for humanity itself. After his death humanity finally lets go of its need for violence and becomes worthy to achieve transcendence.
  • A Hero to His Hometown: For Trikru, he might as well be the Devil. His clan, Sangedakru, remembers him as their greatest champion.
  • Kneel Before Zod: He forces the people he conquers to kneel before him and is merciless toward those who don't, personally killing all the Children of Gabriel himself when they refuse to kneel.
  • Last of His Kind: He is eventually the only Commander left in the Flame , leaving Madi vulnerable to his influence until his expulsion.
  • Meaningful Name:
    • Sheidheda means "Dark Commander" in Trigedasleng. Pretty fitting for the Grounder equivalent of the Devil.
    • His real name is Malachi. As in evil in many languages.
  • Red Right Hand:
    • His face is scarred, and his right eye appears to have been burned out.
    • In a case of History Repeats, Sheidheda loses his right eye again during a duel between himself and Indra.
  • Roaring Rampage of Revenge: Thanks to his corruption, he drives Madi into one of these after Clarke is apparently killed.
  • Satanic Archetype: Sheidheda was so evil during his life that he's treated as a Satanic figure in Grounder mythology, to the point where the Flamekeepers had to come up with a way to exorcise him from future Commanders. He gained this reputation in a single lifetime; Indra, who is in her late 40s, remembers seeing him as Commander when she was a child.
  • Sealed Evil in a Can: If the Flame is the can, then Sheidheda (or, more accurately his mind) is definitely the evil sealed within.
  • Smart People Play Chess: Sheidheda appears to enjoy chess, possibly because of its nature as a strategic game. When speaking with Madi Griffin, Nelson and John Murphy, Sheidheda did so over a game of chess while discussing strategy at the same time with them. White talking with Murphy, Sheidheda indicates that he uses chess to evaluate his opponents and their strategies to see what kind of person they are.
  • Villainous Breakdown: When Madi takes back control of her body, he is not pleased.
    Sheidheda: (while trying to kill Madi) We would have ruled everything! Given birth to a new world in our image. A new perfection! Instead your weakness...has killed us both!
  • We Can Rule Together: Basically pulls a version of this while he is trying to corrupt Madi and turn her into a monster like him.
    Sheidheda: I want you to rule this world as I did the last. I want you to kill everyone who gets in your way. I want you to get revenge for Clarke.
  • Wicked Cultured: Sheidheda is an Faux Affably Evil man who enjoys playing chess, and apparently even knows of Casablanca , as he quotes "I think this is the beginning of a beautiful friendship", after getting Indra and Murphy to agree with his terms.
  • Worthy Opponent: Sees Indra as one of these, and he even treats her with a degree of respect after she submits to him. Of course, this is a sentiment not shared by Indra.
    • Murphy is this for him as a chess player too, and he appears to genuinely like him despite being on opposing sides.
