I am looking for the name of a cartoon that was out either in the 80s or early 90s. It was about a man that can go into a robot suit after using a crystal. He can only be in the suit for a max of a half our before he starts to turn bad. His crystal eventually gets broken and he uses a bigger robot to put his crystal together so that he can get into his suit again. Does anyone know what cartoon that I am speaking of?
