In The Defenders #32 (Feb. 1976), the Headmen were joined by Gerber's newly created Ruby Thursday (Thursday Rubinstein), who ran for President of the United States and was the instigator of the death of another Gerber creation, Omega the Unknown. In the same issue, Doctor Strange declared that Chondu's real name was Harvey Schlemerman, and Jack Norris, husband of the woman whose body was being used by Valkyrie, claimed to have seen him perform.
The Headmen made an appearance in John Byrne's She-Hulk comic, during a period when he was reviving Marvel villains. They had kidnapped She-Hulk for the purpose of giving Chondu a slightly more normal body than he currently sported. She-Hulk had temporarily been convinced her head had been detached and placed on a life-support system but this was not true, as she discovered with the aid of Spider-Man.
They also turned up for one issue of the Defenders vol. 2 relaunch, by Kurt Busiek and Erik Larsen. Chondu had an arachnid cyborg body for this outing.
