A somewhat cowardly hammerhead shark monster created byFinster whose main source of power was a fin on a chain that he wielded. Slippery Shark wielded his boomerang like a sword. Slippery Shark zapped Jason Lee Scott and Tommy Oliver under a trance, putting them through a rivalry against each other. Zordon sent Jason and Tommy together to hunt down Slippery Shark in order to overpower the rivalry spell. Slippery Shark lost his power when his fin was destroyed, then he himself was destroyed by the Megazord's Power Sword.
Later he was revived by Lord Zedd along with several other aquatic-themed monsters.
Years later, Tommy would reference Slippery Shark, declaring, "Oh man, I hate shark monsters!" when he comes up against the shark-themed monster of the week (PRDT:Ocean Alert).
