Throughout The SeriesEdit
Clarke Griffin was part of the 100, a group of juvenile delinquents from the Ark who were sent to Earth. Prior to being locked up, Clarke was a medical apprentice and used those skills to serve as the medic on the ground. After several deaths on the ground, Clarke become a co-leader alongside Bellamy Blake. While in charge, she tried to negotiate a peace treaty with Anya and helped lead the defense against the army of Grounders attacking their camp.
After successfully defending the camp, Clarke and 47 other delinquents were taken by the Mountain Men. She escaped Mount Weather and found her way to Camp Jaha, the new settlement setup by The Ark. Clarke helped create an alliance with the Grounder Coalition, led by the Commander Lexa, to fight the Mountain Men. However, the Grounders broke the alliance, forcing Clarke and Bellamy to irradiate Mount Weather. Unable to come to terms with what they did, Clarke sets off on her own.
Among the Grounders, Clarke's reputation spread, and was now referred to as Wanheda, the Commander of Death. Three months later, she was captured and brought to Polis, where she become the Skaikru's Ambassador. After the death of Lexa, Ontari become the Commander by ruse. Clarke escaped Polis, and begain looking for Luna with several others. They found Luna's clan, but she refuses to become the Commander. Meanwhile, A.L.I.E. has taken over Arkadia and Polis. To stop A.L.I.E., Clarke entered the City of Light and pulled A.L.I.E.'s kill switch, but not before learning that the nuclear power plants were melting down.
Following A.L.I.E's defeat, Clarke warned everyone about the impending nuclear apocalypse, as she began to prepare for the survival of the human race. On Becca's Island, Clarke and company tried to create a Nightblood serums which was revealed to give immunity to radiation. To test for the serum's success, they perform trials on subjects by exposing them to radiation, but when Emori was forced to be a subject, Clarke injected herself with Nightblood to carry out the experiment personally. After escaping to the Second Dawn Bunker, Clarke and others leave to bring back Raven from the island, but end up running out of time. Their group decided to use a rocket to go to space. Unfortunately, Clarke was left behind in order to save her friends and suffered severe radiation poison. However, she survived because of her Nightblood. For six years, Clarke lived in the valley with another young Nightblood, named Madi, whom she fosters.
At the beginning of season 5, Clarke and Madi are living happily together in the valley when a prison transport ship lands there. It becomes clear that they are hostile and Clarke manages to take a few of them down before taken prisoner. When Spacekru comes to the ground Madi tells them that Clarke was captured and Bellamy tells Diyoza to let Clarke go or he would kill everyone aboard Eligius IV. After the bunker is opened Clarke spends most of season five trying to protect Madi and stop her from becoming Commander since that would put her in danger. Clarke betrays Bellamy, Octavia, Wonkru and eventually the prisoners, all to keep Madi safe. At the end of season 5 Clarke finally allows Madi to fulfill her destiny of becoming Commander and lead Wonkru to victory over the prisoners. When McCreary realizes he has lost, he sends a bomb that contains Hythylodium to destroy the valley. Clarke kills him and helps load all the remaining Wonkru members and prisoners onto the dropship before they take off to safety aboard Eligus IV. She reconciles with the her friends and goes into cryosleep with the others. She and Bellamy are awaken by Jordan Green 125 years later while Eligius IV hovers around the Two-Sun Planet.
