Deep in the core of Adrian, the catalyst that keeps all his personalities and souls together and locked in a joint consciousness that forms the key identity of the monster rabbit is a single, destructive force one once knew as "Kiatsu". He is mostly dormant now, due to being shaken up by the events at the laboratory, but perhaps it was for the best. Who knows what that little universally genocidal critter could get up to with even MORE powers than being able to consume the entire universe.

But man, wouldn't it just be good to have a little fun~?
