Toyman is a legacy name used by several villains in DC Comics, most of whom were foes of Superman. One of them, whose real name was Jack Nimball, was a member of the Legion of Doom on Challenge of the Superfriends.
Toyman (real name Jack Nimball) constantly opposes Batman and Robin. He uses all sorts of toys as his machinations for committing crimes. Little else is known about this version of Toyman, who is based more around the campier Batman villains than the Superman villains of mainstream DC Comics continuity.
