Axel Jones and the Mutant Mayham

An orphan 13 year old boy named Axel Jones, who lost his parents from their sickness at the age of 10, now lives alone in the streets of New York. He learned sinjitsu between the ages of 3 and 4, and soon, he became a vigilante called the nightwatcher who protects the city from danger at night. Along the way, he met four 15 year old mutant ninja turtles that he knew 10 years ago, and they all must stop Superfly from hurting innocent people.
