The final feature in Astonishing Tales starred and introduced Deathlok, a conflicted cyborg who predated the popular movie character RoboCop by several years and has become one of the most enduring Marvel characters among those introduced in the 1970s; at least two major iterations of the character, featuring different individuals, starred in series in the 1990s and 2000s. Created by artist Rich Buckler, who devised the initial concept, and writer Doug Moench, the feature ran from #25-28 and 30-36 (Aug. 1974 – Feb. 1975 and June 1975 – July 1976), the final issue. Bill Mantlo scripted issues #32-35, with Buckler himself scripting the finale. Buckler described Deathlok as “an extension of a paranoid fantasy. He was a representation of part of my outlook and world view. He was a culmination of many of the messages in some of the music of the time. He was part of some of the things going wrong in our country at the time. Maybe he was the science that was going wrong.Artist George Pérez made his professional comics debut with a two-page backup feature in issue #25.
