History: The mutant Guido Carosella is an adventurer with the superhuman ability to absorb kinetic energy. He cannot store this energy for extended periods of time and hence he must expend it quickly. He possesses superhuman strength and durability and was a former employee of Lila Cheney, who was a famous rock music performer and a mutant with the power to create a teleportation field.

Carosella has since become a member of X-Factor, and best friend to fellow teammate Jamie Madrox, known as Multiple Man. During his time with the team he clashed with many super powered mutants such as the Nasty Boys, the Mutant Liberation Front, and the Brotherhood of Evil Mutants, and has even gone up against powerhouses such as the Hulk.

During a mission with X-Factor while protecting his former employer, Lila Cheney, Carosella threw himself on a bomb. Carosella was able to absorb the kinetic energy but after he had released that energy, his body could not stand the strain and he suffered a heart attack that put him in a deep coma.

Carosella has recently come out of the coma. His heart still weak, Forge created a device that would give Carosella's heart small amounts of kinetic energy, which would cause it to adapt to his body whenever he needed to use kinetic energy. Carosella is currently spending time recovering from his coma and has since gone back to work for Lila Cheney, who has now become a love interest for Carosella.
