After the death of the first Captain Boomerang, a funeral was held that every villain ever to face the Flash attended. Among the large crowd was an eclectic group of metahumans calling themselves the "Rainbow Raiders", in honor of the late Flash villain. Their sentiments expressed during the service seemed to denote that the group is relatively new to the scene, had little exposure, standing, or experience working together.
During the Blackest Night, the Raiders saw that death was the only victor, and committed mass suicide by drinking poison, Red Raider among them; since they didn't have any emotional ties with the Earth heroes they did not resurrect as black lanterns and stayed dead.
Red possesses some degree of super-strength.
