mindless hulk

is mindless hulk's healing factor fasterbecuse of his "purity" or is his just a rumor

His healing factor probably is faster than the others because he is ''supposed'' to be the strongest incarnation of the Hulk ever.

He doesn't heal because he doesn't really take damage.

Good point.

Maybe you can find some info in the link below.
