Origin
Father to one time Green Lantern Kyle Rayner, born Gabriel Vasquez, and known by various codenames such as Aaron Rayner and Raymond Hauser. While working for the American Central Intelligence Agency, Aaron Rayner’s missions reached such a dangerous level that his wife (Maura Rayner) and baby son (Kyle) become endangered, and Aaron is forced to separate from them. To acknowledge the seriousness of the threat to her and young Kyle, Maura and Aaron together even go so far as to construct and file a bogus domestic violence incident. Due to the breakup of the family, Aaron is forced to leave his wife and son without any financial means and to a rather limited life.
Creation
Created for use in DC Comics by Chuck Dixon. Aaron Rayner’s first appearance is in Green Arrow #111 – Final Appeal which was released in August 1996.
