Hawkgirl’s awesome ability to fly comes from Nth metal, a mystical and otherworldly material that defies gravity and lets this Justice League heroine soar on her bird-like wings. She’s ferocious in battle, swooping in to defeat villains and then carrying them off to prison. As a member of the Justice League, she fearlessly patrols the sky in search of trouble, though she does have to watch out for flocks of passing geese. Bat-Fact: Hawkgirl is the reincarnation of an ancient Egyptian princess. Or maybe she’s an alien space-cop. I can’t keep track of all of these origins.
