Sinker

Sinker is an illegal genetic experiment created by Jumba Jookiba. He is designed to slice enemy sea vessels in half with his large, sword-like dorsal fin. His one true blace is at a Japanese restaurant, cutting up fish fillets and vegetables to make sushi.

Powers
Underwater Breathing: Much like a shark, he can breathe and swim underwater.

Weaknesses
Blind Spot: Due to the blind spot on his large dorsal fin, he will become immobile if forced into a horizontal position.
