Caliban
Caliban was a mutant and a member of the Morlocks. He was characterized by his gaunt, slight frame, albino skin and large, round eyes. Of all the Morlocks, Caliban was the most passive, and did not share their communal hatred of humanity and other mutants. Caliban developed a fondness for teen X-Man Kitty Pryde and took care of her when she had fallen ill due to contact with Plague. Callisto promised Kitty to Caliban as his bride, which he deeply desired, but after seeing how miserable Kitty had become, agreed to let her return to her own people.

Callisto
Callisto was the leader of the Morlocks - a group of mutants, whose physical deformities set them apart from even regular mutants. She maintained the Morlocks' base of operations in a subterranean network of catacombs that she called The Alley. Callisto was presented as a thin, unattractive woman with masculine features, dark, choppy hair and a scar across her face. She also wore an eye-patch over her right eye. Her personality was that of a no-nonsense bad-ass, whose loyalty to the Morlocks is matched only by her hatred of humanity.

Cameron Hodge
Cameron Hodge was one of Warren Worthington, III's oldest friends. They attended school together and were college roommates. After school, Hodge became a successful lawyer and advertising executive. Despite his friendship with Worthington, Cameron Hodge nursed a deep-seated hatred of mutants; a hatred that he kept closely hidden from those who knew him. As part of an extended scheme to turn public opinion against mutants, Cameron Hodge founded the organization known as The Right. He eventually reunited with Warren and manipulated him into forming X-Factor, which consisted of the original X-Men members, secretly working under the guise of mutant hunters. Hodge ultimately betrayed X-Factor and battled up against them as Commander of The Right. He later became part of the techno-organic host entity known as the Phalanx.

Candy Southern
Candy Southern was the former girlfriend of mutant superhero Warren Worthington, III, aka Angel. She met Warren sometime after his initial stint with the X-Men and remained with him during his time with the Champions of Los Angeles. Their relationship continued on through Warren's early days with X-Factor. She was ultimately killed by Warren's best friend and X-Factor benefactor Cameron Hodge, who was secretly the leader of an anti-mutant organization known as the Right.

Charlie Wiederman
Charlie Wiederman was a contemporary of Peter Parker and also attended Midtown High School. Wiederman was bullied even more than Peter, but suffered additionally at the hands of abusive father. As an adult, Charlie developed a vibranium exo-shell that made him invulnerable to most forms of injury and became a supervillain. He burned down Peter's apartment as well as the family home of May Parker in Forest Hills. Spider-Man fought with Charlie at Stark Industries and de-powered him by trapping him inside of an atmospheric chamber.
