Deadpool (Wade Winston Wilson) is a fictional character, a mercenary and anti-hero appearing in comic books published by Marvel Comics. Created by artist Rob Liefeld and writer Fabian Nicieza, Deadpool first appeared in New Mutants #98 (Feb. 1991).
A disfigured and mentally unstable mercenary, Deadpool originally appeared as a villain in an issue of New Mutants, and later in issues of X-Force. The character has since starred in several ongoing series, and shares titles with other characters such as Cable. The character, known as the "Merc with a Mouth", is famous for his talkative nature and his tendency to "break the fourth wall", which is used by writers for humorous effect.
Deadpool was ranked 182nd on Wizard magazine's list of the Top 200 Comic Book Characters of All Time, ranked 45th on Empire magazine's list of The 50 Greatest Comic Book Characters, and placed 31st on IGN's list of the Top 100 Comic Book Heroes. He was portrayed by Ryan Reynolds in 2009 film X-Men Origins: Wolverine.
