They were half-man/half-sharks crime-fighters that kicked ass! STREET SHARKS!
It was university professor Dr. Paradigm that tested his gene-manipulation techniques on a marlin and a lobster. Dr. Bolton, a fellow professor, attempted to destroy Paradigm’s research, and was transformed into an inhuman monstrosity by the evil scientist before escaping. Paradigm later kidnapped Bolton’s four sons—John, Bobby, Coop, and Clint—to transform them into sharks. As soon as they transformed, the four brothers ate a hotdog stand and fled from the police by diving into a lake and burrowing their way into the city by eating the dirt….YEP. That was how it all begin.
Truthfully I never watched the series itself. I was more into the action figures! It was only until later years that I found it was also a show.
