Teenage Mutant Ninja Turtles (2003)

In their underground lair deep beneath the city streets, the Turtles and Master Splinter are suddenly attacked by a horde of Mouser robots!

The Turtles discover the source of the Mouser robots that trashed their old lair: Dr. Baxter Stockman -- a noted technological genius/inventor, who tries to pass off the Mousers as a means to eradicate the city's rat problem.

When April O'Neil wakes up in the Turtle's lair she has major trouble dealing with the reality of four giant talking turtles and a zen-master rat.

Raphael is a little cooped up underground with only his brothers and Master Splinter. When Raphael almost clobbers Michelangelo in some brotherly sparring, it's apparent that Raphael needs to get out let off a little steam. But when he meets up with Casey Jones, a vigilante erring a little to the right of justice, Raphael must face the reality of his own hothead ways.

When a scientist accidentally unleashes a super-powered Nanotech monster with a childlike mind, it adopts a small-time grifter as its father figure, and the mayhem begins!

The turtles investigating a strange blackout, discover the Foot Ninja stealing a Japanese ceremonial sword from the Metropolitan Museum of Art.
