Lexa

Lexa is a recurring character in the second and third seasons. She is portrayed by cast member Alycia Debnam-Carey, and debuts in Fog of War. Lexa is the Commander of the 12 Clans, and is thus the most powerful (known) character in the series.

Early Life
Lexa grew up with The Woods Clan. The clan taught and brought her up to be a fighter/warrior. Her skills were so impressive Anya made Lexa her second. At some point, she began a relationship with a Grounder named Costia. Costia was kidnapped and beheaded by another Grounder clan, the Ice Nation. When Lexa was 16, she formed a coalition between all 12 Grounder Clans and became the Heda of the 12 Clans.

Throughout the Series

 * -|Season Two =

In Fog of War, she is sent by Gustus to oversee Marcus Kane and Thelonious Jaha as they are kept captive underground at a Grounder camp. Eventually when Kane cuts himself to save Jaha, Lexa helps out by covering up with wound. Jaha however quickly takes advantage of the situation and holds a knife to Lexa's throat just as Gustus and the others walk in. Lexa speaks in Trigedeslang to Gustus to let him know that she has the situation under control, and takes down Jaha in a quick swoop, revealing that she was the Grounder commander the entire time. Lexa orders to have Jaha taken away and Kane remained locked in his cell.

In Long Into an Abyss, she is first seen in her tent just outside of Camp Jaha. Clarke Griffin is sent in to discuss terms with Lexa to decide how they can settle their feud and come to a truce. Indra throughout the conversation says that she should just end Clarke now, but Lexa tells Indra to stand down. Clarke mentions Anya, who was the mentor of Lexa, and tells her how they were willing to make peace. Clarke reveals that there is a way to cure being a Reaper, with the Grounder Lincoln as proof. Clarke takes Lexa and her guards to The 100's Camp, where Lincoln is currently residing. Lexa and her brethren look on at their fallen soldiers from the battle that erupted. When they enter the dropship, Lincoln appears to be dead, with Octavia Blake clutching his body in sadness. Before a battle between the two groups breaks out however, Abigail Griffin manages to revive Lincoln through an Ark stun stick. Lexa and Clarke then return to Lexa's tent. Lexa then tells Clarke if she brings her Finn Collins, their will finally be peace with the two groups.

In Spacewalker, she is seen at the end ready to execute Finn. Clarke comes rushing in to beg Lexa to take pity on Finn and to kill her instead. Clarke gives many arguments, but Lexa still argues that Finn is guilty. Lexa then allows Clarke to say goodbye to Finn. However, Clarke spares Finn by stabbing him in the stomach, preventing a more painful death. The grounders are about to attack Clarke, but Lexa tells them to stand down.

In Remember Me, Lexa is seen speaking with Clarke about having their peace ceremony to finally bring peace once and for all with the Grounders and Sky People. Lexa then tells Clarke she must bring the body of Finn to perform a final ritual, to which Clarke agrees. Later she is seen with Gustus, speaking about her safety with the Sky People. Gustus says to be worried, but Lexa brushes him off.

When they finally arrive at the Grounder village, dozens of Grounders are angered by the sight of Sky People. One steps in front of Lexa and questions her leadership, to which Gustus steps in to beat him down, but is quickly stopped by Clarke Griffin to avoid more issues. During the ritual, Lexa allows Clarke to burn Finn's body. After the ceremony, Lexa tells Clarke of her past lover, Costia. Lexa tells Clarke to move on, and showing that she is not ready to move on is weakness.

Finally during the feast, Lexa is offered alcohol during the feast by Marcus Kane. Gustus tries the drink to make sure it is safe. Seconds later however, Gustus is seen hissing and coughing, meaning that the drink was poisoned. Lexa orders that no Sky Person will leave the feast room until they figure out the situation. Eventually they determine that Raven Reyes was the one responsible, and tie her to a post, to perform a torture ritual. However, Clarke saves Raven and it is revealed the poison was in the cups, not the drink, meaning Gustus put it in himself to protect the commander.

Lexa carries out the torture on Gustus, which leads to his death, with Lexa delivering the final blow. At the end she is seen entering her own tent to discuss terms about what their next move with Mount Weather is.

In Survival of the Fittest, she is seen discussing a strategy as to how they will break into Mount Weather to free her people. An angered Grounder named Quint jumps into the conversation and says that they should not listen to any Sky Person. Lexa tells him to stand down, but Quint refuses, saying that she murdered his brother in the dropship explosion. Later she is seen saving Clarke from Quint, who was about to stab her. Clarke says that he killed her guard Major Byrne, to which Quint says she is lying. Lexa then tells Clarke that she must kill him, but Clarke is hesitant. However, the sound of a beast is heard by everyone, and starts to pounce its way through the forest. Lexa then slits the leg of Quint, leaving as bait for the beast.

When Lexa, her guard and Clarke arrive at the beasts compound, the beast jumps in revealing itself to be Monaw, a gorilla the lurks the forest. Monaw swoops in and kills Lexa's guard, with Clarke firing numerous bullets into it. The two run away and hide in its cage, with Lexa using her blade to hold the door. Lexa and Clarke discuss a way to get out, but they are not sure what to do. However they wait for Monaw to burst in, and allow then escape only to lock his cage from the outside. When they exit the compound, Clarke says that the plan they had to put Bellamy Blake as an inside man could be taken another step.

In Coup de Grâce, photographs of her and Clarke are seen being held by Mountain Men who were sent as scouts. This means that Clarke and Lexa are seen as targets by Mount Weather, and their assassination could end the war.

In Rubicon, Lexa is first seen indoors at Tondc about to begin the peace treaty with the other grounder nations. Clarke pulls her aside and tells her that Mount Weather is ready to fire a missile at everyone there. When Clarke suggests evacuation Lexa says that if they evacuate, the Mountain Men will know they have a spy, endangering Bellamy and the mission. Clarke argues desperately to Lexa that the alliances will never hold, but Lexa says it will simply motivate everyone to fight even more. Later she and Clarke are seen slowly exiting Tondc before the missile hits. Lexa sneaks away from the camp to make sure the sniper from Mount Weather doesn't notice she survived the attack.

In Resurrection, Lexa first appears grabbing Clarke and calling for her in the commotion after the missile. She tells Clarke the sacrifice was necessary and nods when Clarke says she wants all of the Mountain Men dead. Lexa and Clarke go after the shooter from Mount Weather to kill him even though she knows it won't make Clarke feel any better. As they head towards the sniper Lexa looks back at the smoking Tondc sadly. Lexa, Clarke, and Lincoln return to the village after the shooter is dead and Lexa addresses the people telling them, "What happened here will not stand. The mountain will fall. The dead will be avenged!" She tells Clarke that they are going to win the war and they are last seen walking towards Mount Weather with their armies.

In Bodyguard of Lies, Lexa is first seen discussing with Clarke on how to approach Mount Weather. Later, when Octavia confronts Clarke about Tondc and how she knows about it, Lexa orders Octavia to stand on watch duty. Octavia says she is to be hunting with Lincoln, but Lexa insists. Later Clarke confronts Lexa to tell her that she knows Lexa planned to get Octavia assassinated, and tells her she can't just kill everyone she sees. Clarke says she regrets Tondc, and is depressed at how many people they let die. Lexa says how she didn't let Clarke die, but Clarke just storms out of the room.

Later when Clarke speaks to Lexa again, Lexa leans in to kiss Clarke, and Clarke kisses her too. However Clarke steps back and says that she is not ready for another relationship, and she needs time to overcome the loss of Finn. When they are informed of the acidic fog being turned off, Lexa yells a speech to her Grounder brethren and charges on Mount Weather.

In Blood Must Have Blood (Part 1), she and Clarke are seen explaining the plan to a group of soldiers on how they will breach Mount Weather. Lexa and Clarke's unit are to wait at the Mount Weather door until Raven and Kyle Wick destroy the generators in Mount Weathers Dam. When they arrive at the door, Lexa and Clarke await patiently as the door is drilled, and the charges are place. When Lexa and Clarke try to press the button to blow the charge on the door, it does not work, and they figure out they must be closer to activate. When they attempt to get closer, Mount Weather gunners outside the door start firing on all of the grounders. Lexa orders a group to flank them, and orders a group to protect David Miller with their shields so he can get closer. When the grounders with shields are gunned down however and David is presumed dead, Lincoln fires an arrow at the charge, blowing it up.

Just before the grounders breach the door, Lexa brings Carl Emerson, a guard at Mount Weather to the door. When the imprisoned members of The Woods Clan walk out of Mount Weather, Lexa says she did her job protecting her people, and the war for her was over, as The Woods Clan and Mountain Men have made a truce. Lexa sets Emerson free, ordering her men to head back to camp, and leaving a speechless Clarke at the front door of Mount Weather.

Personality
Lexa, as leader of the Grounders, commands respect and is very powerful. However, she is clearly seen to be more reasonable and merciful than the other Grounders, and more willing to trust the Sky People. Lexa has shown to be the voice of reason among the chaotic nature of the Grounders, she has a very neutral personality and is more of the logically gifted Grounders yet to be shown. After Costia, the woman she was in love with, was killed by an enemy trying to gain information on Lexa, she decided to detach herself from people emotionally, believing love was a weakness she could not afford to have.

Physical Appearance
Lexa is of average height, slim, with a high forehead, plump lips and youthful face. Lexa wears tribal-like face paint most of the time, but has been seen without it. Like many of the other grounders shown so far, Lexa keeps her hair hair out of her face with a number of layered braids.
