Deadpool (Wade Wilson) is a foul-mouthed, fourth-wall-breaking mercenary with a regenerative healing factor and an obsession with chimichangas. Created by Fabian Nicieza and Rob Liefeld in 1991, he was initially a villain before evolving into an anti-hero beloved for his irreverent meta-humor. Known as the "Merc with a Mouth," Deadpool's willingness to acknowledge he's a comic book character makes him uniquely subversive and wildly entertaining.
