The Hawkman Legacy

Katar Hol is a police officer from the planet Thanagar who travels to Earth alongside his wife Shayera to apprehend a criminal, ultimately choosing to remain and study human law enforcement methods. Equipped with Nth metal wings that grant flight and a mastery of ancient weapons, he adopts the identity of Hawkman and joins Earth's heroes as a member of the Justice League of America.

Carter Hall is the reincarnation of an ancient Egyptian prince who, upon discovering a mysterious anti-gravity metal called Nth Metal, recovered memories of his past life and fashioned a winged hawk-suit to become Hawkman, one of DC's earliest mystery-men.
