DEADPOOL

Deadpool, also known as Wade Wilson, is a mercenary and anti-hero appearing in comic books published by Marvel Comics. He was created by an artist by the name of Rob Liefeld, and a writer by the name of Fabian Nicieza. He made His first appearance in the comic The New Mutants Issue #98, Feb. 1991. Since then, he has become one of Marvel's most used and popular characters due to his humorous personality. He makes his Marvel vs. Capcom series debut in the 2011 game Marvel vs. Capcom 3: Fate of Two Worlds.
Deadpool is a highly unstable individual due to the side effects of his vast healing power, so his personality changes from time to time. He frequently displays multiple potential mental disorders, including: attention deficit hyperactive disorder, manic depression disorder, and recently the onset of schizophrenia.

Deadpool wears a red and black jumpsuit with large oval shapes around the eyes and a logo, bearing his likeness, on his belt buckle. People unfamiliar with Deadpool often confuse him for "a ninja Spider-Man," much to the chagrin of his fanbase (as well as Deadpool himself).
In Marvel Vs Capcom,

Deadpool's first appearance was battling Dante in a building. Later, with the appearance of Galactus and dangerous villains determined to conquer both the Marvel and Capcom worlds, Deadpool ceased battling Dante and turned his attention to stopping the villains.

Deadpool's ending involves him throwing a wild party with various Marvel and Capcom heroes as well as civilian attendees, in celebration of his climactic victory over Galactus; he also thanks "the player in front of the TV", saying that he would invite him if he could, but "[the player] got the Player Points for winning, and that's all you need!". Eventually, Deadpool accidentally overloads Galactus' worldship after attempting to increase power to the DJ booth and margarita machine. The resulting mishap causes the worldship to destroy the entirety of Cleveland city. Police then issue arrest warrants for both Deadpool and the player, with the news media terming the tragic accident "Deadpoolicide".
