Iguanus was the result of one of Mindbender's early mutation experiments on his new island. The fusion of human DNA and reptile DNA created this unstable beast who promptly escaped the lab and now runs wild on the island. One of the few to not have any kind of loyalty to Mindbender, Iguanus is considered an animal and all attempts by Mindbender's creations to subdue him have been a failure. Mindbender still hopes to bring him back in to implant another strand of DNA to teach him obedience.
