Street Sharks

Dr. Robert Bolton had invented a gene-slamming device for peaceful uses until his colleague Dr. Luther Paradigm uses it for his evil purposes. When Dr. Bolton tries to intervene, he ends up gene-slammed into an unseen inhuman creature during the struggle and escapes. While in search of their father, John, Clint, Robert, and Coop are mutated into humanoid sharks by the evil Dr. Paradigm. While adapting to their new looks, the four brothers must avoid being seen.

Jab and Streex are sent back in time in two different eras by Dr. Paradigm's time machine called the Time Slammer. Back in the present, Slammu, Ripster, and Bends have to deal with Dr. Piranoid's Seaviates who are now joined by Shrimp Louie. With the help of some Atlanteans, Jab is able to travel in time to save his brother Streex.

A space capsule that landed on Earth 65,000,000 years ago has been unearthed by archaeologists. While Dr. Paradigm has taken interest in the space capsule, an incident involving the capsule's prisoner Bad Rap causes Mantaman to fall under his control (the alien whose DNA was used to create Mantaman was one of Bad Rap's many creations) as they plot to control the largest radio telescope in order to contact Bad Rap's fellow Raptors. Now the Street Sharks must work to free Mantaman before Bad Rap's transmission to his fellow Raptors gets through.
