The Merc with a Mouth, or Deadpool, was created in 1991 by writer Fabian Nicieza and comic illustrator Rob Liefeld. Though Deadpool walks the line of being a villain himself, he's also fought some of the nastiest evil guys around to help save the planet and humankind... when the price is right, anyway. This anti-hero may not always feel the urge to save the day, he still displays an impressive rogue gallery, and we're here to show it to you.
We've listed all of Deadpool's greatest enemies on here. Who do you think is the best villain this comic book hero's ever encountered? Do you enjoy the rivalry between Deadpool and Madcap, or do you hold Death in a special place in your heart?
