Tough, arrogant and malevolent, 1 has a strong willed ambition to keep himself and the others protected, and is a leader of the group. He is not a bit sympathetic, and doesn't tolerate weakness, but also doesn't encourage strength or courage when it's used in ways he doesn't agree with. Despite this in the end 1 learns that "one must be sacrificed for the good of many", and gives up to the Fabrication Machine, allowing 9 to fulfill his destiny. The Scientist described 1 as trying to escape (like in SAW) after his creation, and being aggresive. 1's skin is fastened by many metal snaps. Voiced by Christopher Plummer.
