As the Acro-Bat, Walter was one of the members of the Justice Experience, a team of heroes that operated during the years prior to the modern heroic age. He, along with many of his colleagues, was killed by Larry Trapp, a man whose wife had been accidentally killed when the Justice Experience squared off against their foes. This experience led one of his two daughters to resent all super-heroes and villains in her adult life.
