Quote:His power works over in marvel, as he is the Impossible man while on vacation there!/quote] That not really fleshed out by either company as both beings appeared in the same universe as two separate entities. I doubt Marvel will let Mxy have the same abilities as he displays in DC. If that were the case then the Infinity Gauntlet should work in DC but it doesn't. Plus you are discounting Higher beings like Protege who can copy any powers
Mxy powers are in imagination, so hard to get higher then that!
