Take for example the case of "Dr. Irwin & Mr. Meteor", a clear parody of Robert Louis Stevenson's Dr. Jekyll & Mr. Hyde. Meek Dr. Irwin Feldspar (Alan Young) runs across a meteor fragment that has crashed to Earth. Contact with the fragment turns him into a metal maniac. Now, how do you suppose Plastic Man (Michael Bell) and friends can stop this schizoid crook?
None of Plas' Rogues Gallery from the books appeared on the show, as DC wasn't using them, either, so Ruby-Spears created a new set of villains that were even more bizarre, some of which were actually parodies, such as Mr. Meteor.
