Teradon (once known as Terrance O'Donahey) was originally the White Dyna Ranger, empowered by the Tupandactylus DynaCell, and a member of the original Dyna Ranger team. However after an intense battle with Evileaf, his DynaCell was damaged and he was exposed to high amount of Tupandactylus bio-genic energy and was evolved into a human/pterosaur hybrid. No longer human or a Ranger, Teradon serves as mentor to the current team of Dyna Rangers
