Ninja Turtles: The Next Mutation (1997)

In this live-action TV series, the Turtles are older than in the movies or cartoon, and are joined by a fifth, female Turtle. "Venus De Milo" mutated with the other 4 Turtles but was washed away with the current in the sewer into New York's Chinatown before Splinter came across the turtles. After learning the Shinobi arts in China for 17 years, Venus has returned to New York. The Turtles are now faced with new villains such as Dragon Lord, Bonesteel and Vam Mi.
