Grinder is a villain from the Power Rangers franchise. He holds the Monkey spirit and a stolen cloning formula was used on him by Camille to multiply him. Scorch didn't want to sacrifice him. The formula had one flaw, the test subject would be left with the worst case of itching. Camille wanted him to conceal himself, but Scorch went to his hiding spot and told him to find the Rangers. Scorch informed Fran, who told Dom, who went one-on-one with the main monkey. He defeated Grinder, he grew big and was frozen by a special ice attack from the Rhino Steel and destroyed by the Jungle Master Stampede. In one last battle, Dai Shi opened a portal to the Spirit World and brought this warrior back, which was defeated by the Rangers and their Masters.
