Canti is a noncombatant! Not that he's defenseless, he can actually take a lot of damage without falling, but he really can't fight effectively. But he won't be attacking if it's avoidable, and even if he does attack it will be pathetic. He hates killing, and will do everything in his power to minimize casualties.

He probably won't be on the ships at all. He doesn't need air, and can fly without propulsion, which doesn't make much sense but hey, flcl.

I'm toying with the dream-shifting idea, but what role he takes in that is still up in the air.
