Created by Doc Schwartz, Zed was a highly sophisticated robot who became a police detective working out of Scotland Yard. A generally amiable character, he was nonetheless passionate about his job and would stop at nothing to bring lawbreakers to justice.
Detective Zed's last original ongoing appearance was in New Eagle #328 but he returned in the 1989 Eagle Annual and several earler stories were reprinted in Eagle's last eight issues in 1993-1994.
