I don't really have a history for Cen. He just kinda shows up and is large. Majestic, but scatterbrained. I guess you could call him a himbo? Do himbos get this fat?
Incendiary "Cen" Cooper has no sense of direction. He has gotten lost in a studio apartment. GPS systems learn how to swear when he tries to use them. On the bright side, he's lucky enough to wind up where he's needed, right in the nick of time. He takes on a variety of temp jobs, depending on where he finds himself, and can generally find good food and cozy lodgings in the deal.
Just, uh, don't give him anything you value when he heads out for the day.
