Mighty Morphin Power Rangers
Rita has her own magic coin, and uses it to make her own evil Power Ranger, the Green Ranger. The Green Ranger fights the good Power Rangers, because Rita is controlling his mind. They free him from Rita's evil magic, but his magic coin stops working the right way, and begins to hurt him when he uses it. The Green Ranger gives up his magic coin to the Red Ranger who will not get hurt by it.
