Last survivor of a planet earth, destroyed by a powerful invading force, lead by "the master of darkness" as they called it.

Fled lonely and afraid, he transferred his mind into a robotic body, then a powerful magnetic storm made him crazy.

He ended into a portal that led him in front of the Chiseled, basically the god of time. He restored his mental state (by making him loose his mind to the point he seems sane again).

When the chaos mafia formed, the agents of the Chiseled brought Kosmo to them, to be their pilot/ spaceship mechanic.

He still feels melancholy for his original solar system and he hopes to see it one day, at least for a second
