History[]
In the past, Octavia was forced into hiding aboard the Ark because families were only allowed one child. Sadly, the secret is revealed and she was sent to Earth along with 99 other teenage delinquents. On Earth, Bellamy becomes overprotective of Octavia as she wants to enjoy freedom. She meets Lincoln and with Finn try to make peace between the Grounders and the 100. In Season 2, Octavia meets Indra who introduces her to Grounder's life and combat. She also helps the 48 escape Mount Weather. In Season 3, she witnesses the death of Lincoln, executed by Pike, the new Chancellor of Arkadia who wants to wipe out the Grounders. From that moment on, Octavia grew cold and vengeful and turned her back on Bellamy whom she held responsible for Lincoln's death. She also helps defeat A.L.I.E. and take the opportunity to kill Pike who was helping her and her friends, impaling him with a sword.
In season 4, she still suffers from Lincoln's death and gets close to another Native Ilian who sabotaged Arkadia to get revenge on Skaikru over A.L.I.E.. Octavia also participates in the conclave which will decide between the Nations who will survive in the Second Dawn bunker during the Praimfaya. She gets the help of King Roan and Ilian and she kills Luna, winning the conclave. At the start of Season 5, with Jaha's help, Octavia calms tensions between the Nations and demands that they reunite together or else they die. After that, she becomes Blodreina and organizes fights in a pit. She also resorts to cannibalism advised by Abby. When the Eligius Prisoners arrive on Earth, Octavia declares war. Finally, she goes back to space with all the others after the Damocles event.
In Season 6, Bellamy wants to leave her in cryo so that she does not wreak havoc on Alpha but she is finally awakened by Niylah and then she confronts Kane. Octavia arrives on Alpha with Diyoza and they meet Gabriel also known as the Old Man. Like Diyoza, Octavia disappears in the Anomaly. In Season 7, we learn that Octavia lived on Skyring with Diyoza and her daughter Hope. She also gets closer to the disciple Levitt who becomes her boyfriend. Octavia also stops the war between the Disciples and Wonkru. She transcends with her friends and is last seen welcoming Clarke who hasn't transcended.
