Kirby's signature skill is his ability to inhale objects or creatures and spit them out as projectiles, as well as the ability to suck in air to float over obstacles. His Copy Ability grants him the power to adopt the abilities of the creatures he inhales, while also wearing various costumes or transforming his shape.
The origins of the being known as Evil Deadpool are tied to Ella Whitby, a British psychiatrist obsessed with the super-human mercenary Deadpool. She collected numerous parts of Deadpool's body that he had lost over the years, and kept them in her freezer. When Deadpool found them, he threw them in a dumpster in disgust. The parts eventually thawed and, since they all had Deadpool's healing factor, fused together into a single person.
