The second Deathlok, Michael Collins, debuted in the miniseries Deathlok #1-4 (July-Oct. 1990, reprinted as Deathlok Special #1-4 the following year). He was the second Deathlok to be created in the modern era and also the second to be created for the traditional Marvel Universe. This second Deathlok went on to a 34-issue series cover-dated July 1991 to April 1994, plus two summer annuals in 1992 and 1993.
Professor Michael Collins was born in Philadelphia, Pennsylvania. He was a pacifist working for the Roxxon Oil cybernetics corporation Cybertek. Upon discovery of the Deathlok program he was shot with a sedative by Harlan Ryker and his brain was transplanted into the body of the John Kelly Deathlok Cyborg. The machine was used against rebels fighting against Roxxon’s influence in the fictional South American country of Estrella. Collins regained his consciousness during that mission and stopped the cyborg programming that would have killed a small child.
