In his first appearance, Fero is described as a scientist of the occult, a super-detective of the nether world, who is the one man who can thwart the evil doings of vampires and werewolves that have invaded earth from Pluto. Fero's later adventures had him working on cases involving more standard criminals.

Fero operated out of an office in New York at some point in the distant future.

He was a skilled detective and scientist (including some form of forensic pathology) and a good fighter. He did not seem to carry any weapons, but did wear a "ray proof jacket." He also carried pills that could transform him into a giant ape-like creature with superhuman strength, pills that could transform an adult into a young teenager and pills to immediately reverse these conditions. He owned his own interplanetary ship, full of scientific equipment, including a device which could record images of a person's memories.
