Sharkjaw

Sharkjaw is a shark-like Nighlok that can spin around into a destructive force. He attacked the city until the Rangers arrived. Sharkjaw managed to knock down Antonio before retreating back to the Netherworld upon drying up. After Sharkjaw replenishes himself, Master Xandred then tells Sharkjaw that General Gut would take over the attack on the human world.

Trivia

 * Nobody knows if he ever has been defeated after this. Master Xandred may have destroyed him because he was no longer needed.
