Chainsaw

A cyborg wolf who washed ashore on Luka's island-boat one fateful day. She was "rescued" by the Sea Ninjas after a terrible accident, and they used her to test thier new tech in hopes of making her a brainwashed weapon. When she rebelled, Pearl the Dolphin sent her to be eaten by sharks, but the sharks were also rebels who helped her escape.

She convinced Luka to help her get her mate, Flamethrower, back, but she and his friends inadvertently destroyed the entire base, and disbanded the ninjas.
