Doctor Occult, the "Ghost Detective" is a private investigator who specializes in cases involving the supernatural, and whose recorded exploits began in 1935. Although Doctor Occult usually wore normal clothing, a group of mystics known as the seven, once gave him a costume to wear into battle against the evil alien Koth. Hence Doctor Occult lays claim to have been the first costumed hero of the Golden Age!

Doctor Occult often provided assistance to Detective Captain Ellsworth of the police department of his home city on cases involving the paranormal.

Doctor Occult was sometimes aided by his close friend, Rose Psychic, who, like himself, possessed certain mystical abilities.

In the course of his career, Doctor Occult battled vampires, ghosts, zombies, mystical cults and various criminal scientists wgo used methods that were apparently supernatural.

Doctor Occult's last recorded adventure ended with him and Rose journeying through an astral plane, intending to re-emerge on Earth at the headquarters of the leader of a criminal protection racket. They never appeared and their current whereabouts remain a mystery.

Doctor Occult  has the powers of astral projection, hyprinosis, illusion, and telekinesis. He also carries  a amulet that can spellbreak and cast spells, which is the symbol of the Seven.

Doctor Occult is an reserve member of the Justice Society of America.
