This Deathlock eventually was sent to present day earth 616 where he clashed with a few superheroes such as the Thing and Devilslayer. Years later, a fellow employee of Luther Manning named Mike Travers became another Deathlok. Some time later Deathlok was recruited by X-51 (Machine Man) of Earth-9997 into his group of Heralds. At the end of their mission, this X-51 used a device to create a new body for Manning from his DNA and offered him a chance to regain his human life.
