The Merc with a Mouth takes on the Mutant with the Muttonchops in their greatest battles-and occasional team-ups!

Katanas and claws clash in their brutal first meeting-but when someone targets Weapon X survivors, Wolverine must ride to Deadpool's rescue! Doctor Bong tolls for our heroes, then things get hairy over a werewolf!

And when a bounty is placed on Logan's head, guess who tries to collect!

An assault on a Hydra base will have them at each other's throats, while Wolvie plays straight man to Wade's wisecracker in a showdown with a Shi'ar robot.

But things really go off the deep end in the main event-one ultimate, over-the-top, slicing-and-dicing slobberknocker!
