His official powers and abilities via Wiki -
Although Crossbones does not have any superhuman powers, he is still a very dangerous combatant; he kills lesser superheroes and villains with ease and has gone toe-to-toe with Captain America on a number of occasions. Crossbones is one of the world's best hand-to-hand combatants, with extensive training in street-fighting, military combatives, various forms of martial arts, and is a student of the Taskmaster. Physically, Crossbones is tall and very heavily muscled, but moves with an athletic grace uncommon for a man of his bulk. He is a skilled pilot and driver. In addition, he's an expert marksman with guns, bows, and throwing knives. Crossbones usually arms himself with a fighting knife and a small collapsible crossbow, and various throwing daggers, and spring-loaded stiletto blades in his gauntlets. He also has some experience with torture and brainwashing, having effectively "reprogrammed" Sin,[volume & issue needed] and nearly so with Diamondback.[volume & issue needed]
As a member of the Thunderbolts, Crossbones was exposed to corrupted Terrigen Mists during a mission, and shortly after manifested the ability to generate a circle of energy in front of his face which could fire energy beams capable of piercing and burning his targets. The ability developed to the point where flames engulfed the entirety of his head while still allowing him to fire focused energy beams, though these flames could seemingly be doused in water. While his power is active, Crossbones does not appear to be entirely impervious to the flames he generates; after the flames died following his first usage, his mask appeared to have been burnt away and his face was heavily scarred.
