Shaw is a mutant with the unique ability to absorb all kinetic and thermal energy directed at him and use it to augment his strength, speed, stamina and recuperation capabilities to superhuman levels. He absorbs the energy of any impact he is struck by, including not only direct physical blows, but also the impact of bullets and throwing weapons, and less successfully, concussive energy beams; notably Cyclops ' optic blasts. By absorbing successive blows from an opponent, Shaw can surpass the physical abilities of said opponent and then overpower them. His speed is the attribute most dramatically increased by his power; after absorbing enough energy he can attack more quickly than opponents can react. He is sometimes shown to be capable of absorbing the cutting, piercing and thrusting energy from a blade. His powers can enable his body to withstand cutting from adamantium, but only for a short time.
