Deadpool

Deadpool is a fictional comic book mercenary, anti-hero and occasional supervillain who is published by Marvel Comics. Deadpool (real name Wade Wilson) was created by Rob Leifeld and Fabian Nicieza in New Mutants Volume 1, Issue 98, and went on to become a frequent antagonist of X-Force and Wolverine before receiving his own series. Deadpool has a superhuman rate of healing, carries a small arsenal of bladed weapons and firearms, and wears a personal teleportation device in his belt. Deadpool, like Wolverine, gained his superhuman powers from the Weapon X Project (though Deadpool was in a later iteration of the Project). Most recently, he was erroneously thought to be the man called Agent X. He is infatuated (sometimes to the point of obsession) with the former X-Force member Siryn, and is currently partnered with former X-Force leader Cable.

Leifeld's critics point out the number of similarities between Deadpool and Deathstroke the Terminator, a character created for DC Comics' Teen Titans by George Perez in the 1970s. Both characters' costumes share similar themes, both are mercenaries who use similar weaponry, and (most tellingly) Deathstroke's real name is Slade Wilson, while Deadpool's is Wade Wilson. Deadpool's relationship with Siryn also mirrors Deathstroke's relationship with Terra.

Deadpool's name is likely taken from The Dead Pool, a Dirty Harry movie starring Clint Eastwood.
