Many months after the defeat of Kai, the Teenage Mutant Ninja Turtles have reunited with Po and the Furious Five, but not in the way that they expected as they embark on new and exciting adventures in the Big Apple itself.
After fighting a large group of Kraang, Raph and Leo wake up in a forest. It isn't long until they are found and invited to the Jade Palace. Raph is forced to accept due to his elders condition, who is badly hurt.
While going for their usual patrol, the Turtles suddenly find themselves in the Valley of Peace with no memory of how they got there. And now their supposed to be these legendary guardians of the guy called "The Dragon Warrior"? Things can only get weirder from here.
