Ranger history: Adam was the second Black Power Ranger and the first (and only) Green Zeo Ranger.
Adam Park was one of the more quite and reserved Rangers. He was wise and shy but he was also a fierce warrior with a bit of a smart-ass sense of humor from time to time. He liked to teach martial arts and he befriended a shy young pupil that reminded him of himself in many ways. (This was during his MMPR days.) He became the Green Zeo Ranger after he lost his Mastadon/Frog powers. He then became the first Green Turbo Ranger. He passed on his powers to Carlos. He eventually used his damaged power coin to become the Black Ranger one last time. He works as a pro stunt man around Angelgrove now.
