don't know enough about him, seems like yet another Prof. Hulk type.
dunno whether the "will himself to heal" is actually better or worse than the automatic healing that regular/WWH Hulk has.
I would have thought he would be stumped to find time to pause during a fight and heal himself...
It is WORSE!
Now, in pitched battle, he has to stop and fix each injury, and hope that BiBeast will say, "Oh. Ok. Take care of that broken bone. I'm gonna have a "Coldie".
