Cannonball is a mutant.

Thermo-Chemical Energy Field Propulsion: Cannonball possesses the ability to bodily generate thermo-chemical energy and release it from his skin. This energy is used as thrust to cause his body to be propelled through the air, like his namesake, at great heights and speeds with considerable maneuverability. He can control his speed and direction through sheer act of will. At first he could only release this energy from his feet, but now he can fire it from almost any part of his body, to a wide variety of effects, such as channeling it into bio-kinetic blasts from his hands. His power levels have varied over the years - but at his peak, he has been able to defeat the Shi'arImperial Guard leader, Gladiator, and devastate several city blocks by plummeting to the ground from high altitude.

Blast Field: This energy also manifests itself as an impenetrable and virtually indestructible “blast field”. He can use this blast-field to function as a personal shield or extending it to encompass others, shape the field around another person to imprison them, or absorb outside kinetic impact into his own energy supply and then re-channel it to increase the bludgeoning power of his blows or create explosive shock waves upon impact.

Superhuman Durability: When he is using his superhuman powers, Cannonball possesses superhuman durability due to the energy field that forms around his body.
