Powers

 * Martian physiology: Like all White Martians, M'gann possesses several incredible powers, such as superhuman strength, near-impenetrable skin, telekinesis, telepathy, shape-shifting, intangibility, and even the power to defy M'gann Morzz - alien.jpg.]]gravity.
 * Longevity: M'gann's life span is considerably longer than a normal human and likewise ages much slower. As proved by being on Earth for centuries.
