Pangolin

Pangolin is a creature who rolls upwards and has an supposedly impenetrable shell. He is utilized after the failure and mutiny of the Five Fingers of Poison. He has the ability to feel out fault lines and ground instability. Armed with knowledge gained from this ability he then attempts to create an earthquake to destroy the city. The rangers are forced to learn new techniques to battle him but in the end they prevail, bith in ground skirmish by using the Jungle Mace, and in Megazord battle, with Master Phant's animal spirit.
