Octavia

Octavia is uninhibited and fierce. After being hidden her entire childhood in order to keep from being discovered Octavia is free for the first time in her life, something she embraces even as she struggles with it. She is brave and self-confident. Octavia has a short temper and is prone to outbursts and violence. She sees only in black and white, and judges people harshly as a result. She cares deeply for the people she loves, including her brother Bellamy and her deceased lover, Lincoln. Octavia is shown to be much more violent and after becoming Indra's Second, she more and more acts like a Grounder in her approach to violence. Winning the Final Conclave, Octavia become the leader of Wonkru. While at first she tried to benevolent, Kara Cooper's coup forced her to take extreme measures. Similar to how things were on the Ark, she made all crimes capital crimes, punishable by fights to the death. Two years later, when food supplies ran short during the "Dark Year", Wonkru had to cannibalize the dead. Abby advised Octavia that eating should be required, and told her to punish those for not eating. Later, Octavia killed three people for refusing to eat. This event made Octavia think of herself as a monster, which causes her to become even more darker and ruthless. After six years in the bunker, Octavia emerges as a brutal dictator willing to kill anyone who challenges her power. She orders to kill any defectors and is willing to use parasitical worms in Shallow Valley. Octavia initially accepts Madi even though, as a Nightblood, Madi is a potential threat to leadership. Later, Octavia intends to execute Clarke, who is Madi's mother figure, without telling Madi and while using her to conquer Shallow Valley. She doesn’t actually exicute Clarke. Her main weapon is a sword but she knows how to use other weapons. She is an amazing fighter and a strong person. After the Final Conclave, the remaining eleven Grounder clans (all of Floukru died) and the Sky People were merged into a single clan, called "Wonkru", thus succeeding the Coalition. Led by Octavia Blake, they survived the Second Nuclear Apocalypse together within the Second Dawn Bunker.
