Teenage Mutant Ninja Turtles (or TMNT for short) is a computer-animated Nickelodeon series based on the long-running franchise of the same name, which Nickelodeon purchased ownership of in 2009. It ran from September 29, 2012 to November 12, 2017. It was succeeded by Rise of the Teenage Mutant Ninja Turtles in 2018.
When ninjutsu master Hamato Yoshi and his four pet turtles are exposed to mutagen, they undergo major physical transformations: Hamato Yoshi becomes a humanoid rat under the name of Splinter and the turtles become human/turtle hybrids. Splinter retreats to the New York City sewers, where he raises the four turtles as his sons and imparts to them his knowledge of ninjutsu.
After venturing to the surface for the first time, the teenage Turtles discover an alien race called the Kraang is planning to take over New York City with their plans involving the same mutagen that created the Ninja Turtles. The Ninja Turtles befriend April O'Neil when she and her father Kirby have been abducted by the Kraang. While Kirby remains a prisoner of the Kraang, April becomes an ally of the Ninja Turtles as they help her to find out where the Kraang have taken her father. The Ninja Turtles also learn that Splinter's old enemy, The Shredder, is leading the Foot Clan into tracking down Splinter and his sons to put an end to their clan.
