Due to his Kree physiology which had evolved to cope with the heavier gravity of home planet Hala, Mar-Vell was significantly stronger and more durable than a normal human. As a soldier, he was trained in all forms of Kree combat, possessed a superior knowledge of tactics, and was equipped with a device called a "universal beam" (or "uni-beam"); which was at first a handheld pistol before Mar-Vell converted it into a wrist-mounted device capable of projecting energy, emitting beams of pure darkness, and controlling magnetism.
