In the 1980s, Banner once again gained control over the Hulk, and gained amnesty for his past rampages; however, due to the manipulations of supernatural character Nightmare, Banner eventually lost control over the Hulk. It was also established that Banner had serious mental problems even before he became the Hulk, having suffered childhood traumas that engendered Bruce's repressed rage. Banner comes to terms with his issues for a time, and the Hulk and Banner were physically separated by Doc Samson. Banner is recruited by the U.S. government to create the Hulkbusters, a government team dedicated to catching the Hulk. Banner finally married Betty in "The Incredible Hulk" #319 (May 1986) following Talbot's death in 1981. Banner and the Hulk were reunited in "The Incredible Hulk" #323 (Sep. 1986) and with issue #324, returned the Hulk to his grey coloration, with his transformations once again occurring at night, regardless of Banner's emotional state. In issue #347 the grey Hulk persona "Joe Fixit" was introduced, a morally ambiguous Las Vegas enforcer and tough guy. Banner remained repressed in the Hulk's mind for months, but slowly began to reappear.
