Here's where you meet some other good guys. I thought I'd change where Shark HQ is 'cause I figured under a hockey rink is already taken.

Lena Mack: Lena is a student of Dr. Paradigm's who suspects that he's not as good-natured as he makes himself out to be. Her suspicions prove right when she rescues the Street Sharks and discovers what he has done to the Bolton brothers. She helps the brothers whenever she can.

Brendon "Bends" Banner: Bends is Fission University's technical genius. He supplies the Sharks with their motorbikes and other gear. He also provides them with a hidden base underneath the Fission City monster truck rally. Him & Jab have been friends for years, also he still tries to keep the Dynamic Duo (what he calls Sara & Josh) out of trouble.

Moby Lick: Moby Lick was an attempt by Dr. Paradigm to create a fourth Seaviant, using an old friend of the Shark's nicknamed Jets. After first dosing him with an experimental mind control serum, Dr. Paradigm then gene-slammed him with a killer whale. Moby Lick has a long, prehensile tongue (the source of his name), great strength and the ability to suck up water and then expel it through his blowhole.

Rox: Rox was a famous rock star named Melvin Kresnik before Dr. Piranoid accidentally turned him into a bull shark. Dr. Piranoid had wanted to change all the people in a concert into mutants by combining popcorn with shark genes. Ultimately, the Street Sharks stop Dr. Piranoid and Rox was the only one transformed.

Mantaman: In one episode, Dr. Paradigm ventured into space to examine an alien specimen found encased in stone by a scientist. The alien wasn't dead however, but merely in suspended animation, being reactivated by Paradigm's meddling. The scientist (named Terrence Morton) then deliberately gene-slammed himself with a combination of the alien's DNA and manta ray DNA to help the Street Sharks fight the alien.
