Im a realy big fan of the aggressiv mutant and of course would öike him to cut all his adversarys to pieces.
Wolverine is very lethal and beats the vast majority who dares facing him, not the least if its a close range combat.
Regeneration at a very high level and bones covered in Adamantium as well as claws that may cut threw close to anything.
oomsday is a behemoth beyond the mutants level, an opponent for characters as Superman, Shazam or Martian Manhunter. Wolverine is without a chans in this battle !
