when it seeks to reclaim its missing energy. Powers and abilities 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. When manipulated by "Zo" (actually Zarek, the Kree Imperial Minister), Mar-Vell became greatly enhanced, having his physical abilities augmented to the point of crushing the hardest substance known to the Kree, and gained the ability to generate illusions, teleport to anywhere in the universe and fly at faster-than-light speeds.

After his encounter with Eon, Mar-Vell used solar energy to fly, leaving a sparkling trail of photons in his wake. Once named the "Protector of the Universe" by Eon, Mar-Vell gained "cosmic awareness", which allowed him to detect direct threats and perceive changes in the universe. This awareness was also used internally, and alerted Mar-Vell to his terminal cancer.

Mar-Vell contracted terminal cancer in a battle with the villain Nitro. He ultimately perished surrounded by friends, family, and comrades. Surprisingly in a universe where resurrections happen every other hour, Mar-Vell has yet to return to life. It remains to be seen whether that will stay true, but in life or death, Captain Marvel remains one of the most influential heroes in the Marvel Universe." David Harth of CBR.com described Mar-Vell as one of the "best cosmic heroes in Marvel comics," saying, "The Marvel universe
