Ronald Raymond, Apache Chief, Robin, and Wonder Woman get caught up in an island mystery when a science experiment goes awry after Batman and Professor Stein went missing when on their way to the Tokyo Science Expo with Professor Stein's Omnicaster. A scientist named Dr. Dan Corwin had walked into what is referred to as a Geneto Beam and is turned into a Dinosoid, which means half-human/half-dinosaur. His partner flees and hides in the jungle... it's up to the estranged scientist, as well as Ronald, Robin, and Apache Chief to track down the evil scientist and transform everyone back to normal.
