Strictly speaking, Captain America possesses no superhuman powers; however, his body has been mutated to the pinnacle of human perfection. He possesses strength, agility, endurance, speed, and reflexes superior to any Olympic-level athlete, and his bodily functions have been enhanced to the peak of human efficiency. His body eliminates excessive build-up of fatigue-producing poisons in his muscles, granting him phenomenal endurance.

Captain America is an expert hand-to-hand combatant and a skilled martial artist in a number of disciplines; he is also a master strategist, acrobat, and pilot, with training in various military disciplines. He is fluent in Russian, German, and possibly other languages.

Captain America carries a virtually indestructible shield composed of a unique Vibranium-steel alloy created through a process that has never been duplicated. A concave disk two and a half feet in diameter and weighting twelve pounts, the shield has excellent aerodynamic properties and can be hurled to rebound off of solid objects with minimal loss of angular motion. Captain America has long since honed its use to the point that he can use it to defflect attacks and knock out adversaries in tandem with his own acrobatic skill. The shield is impenetrable by even the strongest Adamantium, resistant to all temperature extremes, and unaffected by any known form of radiation; the only way it can be damaged is by the direct breakdown of its molecular bonding.

Captain America frequently travels via a custom-built Harley-Davidson Custom Special motorcycle with S.H.I.E.L.D. modifications and/or a custom-built Chevrolet van outfitted by the Wakanda Design Group; he uses Avengers Quinjets when necessary.
