Get lean, mean, and green with the Turtles team! Join Leo, Donnie, Raph, and Mikey as they take to the streets of NYC, where every turn yields a new enemy. Get ready for non-stop battles against Kraang-droids, mechanical Mousers, a mutant alligator, and even the evil Shredder himself.

The Turtles encounter their very first fanboy, a teenager who dresses up in a costume to fight crime as: The Pulverizer! Then, The Pulverizer is back, and this time the Turtles actually want his help to battle Shredder and stop him before he creates a mutant army. Finally, Donnie's attempts to invent a cure for the mutated Pulverizer are interrupted when the lovesick teenager escapes and terrorizes April as Mutagen Man!

The Triceratons have destroyed Earth. Everyone is gone, including Master Splinter. But the Turtles were saved at the last minute by the Fugitoid. Now, they must travel back in time, and through outer space to find the three pieces of the Black Hole Generator used by the Triceratons in order to save the world!

A Mousers attack has separated the Turtles from their master! But they get more than they bargained for when their search for Splinter leads them to a building connected with their mutation.
