The Deadpool Legacy

Wade Wilson is a wisecracking mercenary with a severe healing factor—the result of a rogue Weapon X experiment that attempted to treat his terminal cancer by grafting Wolverine's regenerative abilities onto his cells, leaving him physically scarred but virtually unkillable. Armed with swords, guns, and an unstoppable mouth, he burst onto the scene picking a fight with the New Mutants before carving out a reputation as Marvel's self-aware, fourth-wall-breaking 'Merc with a Mouth.'

A separate character operating under the Deadpool mantle in Marvel's Modern Age, distinct from Wade Wilson, embedded in the mercenary's chaotic corner of the Marvel Universe — but the specifics of this identity's background remain unclear from available records.
