The Thunderbolt
A friendly dinosaur-like creature, Surla, accidentally eats some radioactive rocks and becomes electrified. Going on a rampage he attacks the Herculoids, taking down Igoo and Tundro with ease. The Herculoids revive and manage to trick him into draining off his energies and reverting to his friendly self.
