History[]
In Season 1, Octavia arrives on Earth with the other delinquents and is the first to put her foot on the ground before shouting "We're back bitches!". She follows Clarke, Finn, Jasper and Monty to go exploring and foraging for food and is attacked by a mutated river snake. She also meets Grouder Lincoln with whom she falls in love despite Bellamy and the other Delinquents' mistrust.
In Season 2, she meets Indra and other Grounders and she will begin to adopt their way of life and methods of combat. She will help Sky People and the Delinquents fight the Mountain Men. In Season 3, tensions rise between Bellamy and Octavia when he betrays her to join Charles Pike's faction that aims to wipe out all the Grounders. He's also the one who kills Lincoln with a bullet to the head and Octavia fatally beats Bellamy in revenge. At the end of the season, Octavia impales Pike with her sword following the defeat of A.L.I.E..
In season 4, Octavia participates in the conclave to represent Sky People in order to decide between the nations that will live in the Second Dawn bunker. She ultimately wins thanks to Roan's help and she kills Luna. In Season 5, she becomes Blodreina by stopping the first conflict between Sky People and the Grounders. She then leads a war against the Eligius Prisoners to obtain Shallow Valley. Then, she flees the Earth with all the others and is placed in cryo sleep while the Earth becomes fertile again.
In Season 6, she is awakened by Niylah and Octavia confronts Kane about her betrayal with Diyoza. She then descends on the Alpha Moon, which displeases Bellamy who did not want her to cause chaos. Along with Diyoza, she meets Gabriel Santiago and suffers the effects of the Anomaly on her arm.
