Freakmaster does not have any superhuman powers but he is extremely wealthy, owning an entire island as well as scientific equipment that surgeons in his employ use to transform others into grotesque-looking members of his Freaks. He is also quite skilled at manipulating others.
Freakmaster's parents were freakshow attractions at the Quentin Carnival. Ralph Quentin, the owner of the carnival, abused them and inadvertently caused their deaths. Vowing revenge Freakmaster went out into the world, becoming vastly wealthy. Freakmaster lived on a remote tropical island which he populates with both natural born freaks and those he creates through surgical procedures. He sent his employee Mr. Renaldo to the Quentin Carnival to procure the freak known as Jeremy. Johnny Blaze (Ghost Rider) who was working at the carnival at the time tried to stop him.
