Nighthawk is the name of several characters appearing in American comic books published by Marvel Comics. There have been several versions of the character: two supervillains-turned-superheroes from the mainstream Marvel Universe continuity (Earth-616), Kyle Richmond and Tilda Johnson ; two S.H.I.E.L.D. agents, Jackson Norriss and Joaquin Pennyworth; five from alternate universes, who belonged to various incarnations of the Squadron Supreme, including Kyle and Neal Richmond of Earth-712, and an African-American version of Richmond from Earth-31916 who primarily kills white supremacists and mentors Tilda upon traveling to Earth-616; and a simulacrum of Richmond created by Mephisto and programmed by the Power Elite to serve as a member of the Squadron Supreme of America under the command of Phil Coulson.
