As the elder, he is the self-declared leader of the group. He is clever and sly, but also
domineering, quick-tempered, and threatened by the new arrival of 9, whose higher intellect leads him to question authority.
2 is a kindly but now frail inventor and explorer who embodies the Scientist's strong creative spirit. An inquisitive personality, 2 is fearless. Director Shane Acker affectionately describes him as a "salty old dog".
3 and 4 are the scholarly twins who voraciously catalogue everything they can see and find, recording and building a massive database of the world that surrounds them and the history that led up to their creation.
5 is a caring and nuturing engineer - the loyal, big-hearted "common man" who is always trying to play the peacemaker. He is also an apprentice of 2, with whom he shares a special bond.
6 IS the group's visionary. Although reclusive and eccentric, his bursts of artistic inspiration through drawings made from his pen nib hands may be keys to help his fellow punk beings navigate their darkest hours.
7 is the group's sole female. A fiercely independent adventuress she has been out patrolling the wasteland. To survive, she has adapted, finding the bones of a deceased bird and crafting her signature skull helmet.
Armed with a giant kitchen cleaver and half a scissor blade, the none-too-bright muscle and enforcer of the group, 8, is created to help the others physically survive the dangerous post-apocalyptic world.
Despite being the neophyte of the group, 9 convinces the others that hiding will do them no good. They must take the offensive if they are to survive, and they must discover why the machines want to destroy them.
