Wolverine: Origins Vol. 5 - Deadpool

Collects Wolverine: Origins 21-27. Wolverine and Deadpool go head-to-head in a battle to the finish! Two men, both products of the Weapon X program, both highly trained killers. One claims to be the best he is at what he does, though what he does isn't very nice - but the other is the Merc with a Mouth, and he might just have something to say about that claim!
