Deadpool is the superhero name of Wade Wilson, a popular character from Marvel publishing. He is a former CIA killer who became a mercenary and then a superhero more or less against his will. Indeed, he found himself with a mutation allowing him to regenerate almost infinitely after scientific experiments aimed at curing his terminal cancer. But these experiments also left him disfigured and for this reason, he never leaves his costume covering him from head to toe. The X-Men have tried to recruit him several times and he will end up working with some of them in some comics but he finds them generally too nice” and boring. Deadpool is a very offbeat character who shows both sociopathic personality traits but also has a wacky sense of humor that readers really enjoy. For example, he has a passion for unicorns, loves to dress up and regularly breaks the 4th wall in his comics.
