Hawkgirl is Shayera Hol. She is a superheroine and is a reincarnation of the Egyptian Princess Chay-Ara. Hawkgirl owes her powers to a belt of nth metal, a substance native to the planet Thanagar. The metal is psycho-reactive, responding to its bearer's thoughts and in its base form has a number of electromagnetic/gravitational properties. It grants the power of flight, superhuman strength, super-acute vision, and an enhanced healing/regeneration ability.
