Island of the Dinosoids

While transporting Professor Martin Stein (one half of Firestorm) and his new omnicaster in the Batplane, Batman and the plane crash-land on an island. The Super Friends go to the island to rescue Batman and Professor Stein, but encounter a reptile-man dinosoid calling himself Dr. Corwin, who has created a genetic manipulation beam that can change any animal into its dinosaur counterpart. Corwin has also turned Batman and Stein into reptile men, and after Wonder Woman is also transformed, the Super Friends must restore them to normal whilst fighting Corwin's dinosaur army.
