Shellshock

Shellshock
A tortoise monster created by Squatt and Baboo, Shellshock had a traffic light atop its body which created speed and freeze spells. For hand weapons, he had a hook and a baseball bat with a ball, as well as a large cannon in his shell. He was exceptionally powerful but lost some of his power when Trini shorted out his traffic light using the deandra flowers. In the end, he was destroyed by the Dragonzord & Tyrannosaurus Dinozord. Some time later when the Rangers were sent to the Island of Illusion, they were assaulted by the illusions of monsters they had already defeated, including Shellshock. Shellshock appears in Mighty Morphin Power Rangers for the Game Gear as the boss of the fifth level.
