While living dual lives as high school students and ninja heroes in New York, the Teenage Mutant Ninja Turtles face a more terrifying threat. After another failed Mousers attack, TCRI has gained the aid of a mysterious vigilante called the Shredder and his Foot Clan. TCRI is planning to open a portal to a certain dimension where a cosmic energy can be used as a fuel source for weapons and advanced mutagen. Shredder is helping them because an important ally (possibly Karai) is trapped in the very dimension. The dimension is home to an alien overlord known as Krang. Meanwhile, the Turtles struggle with upcoming standardized tests and who they should ask to the prom. During some battles, a few of the mutant friends turn against the Turtles and join the Shredder's gang. Exciting parts will include dimension-jumping and the Turtles meet different versions of themselves (from Kevin Eastman's original comics, from the '80s cartoon, from the 2003 series, the 2012 show, the tacky 90s movies, and the 2014 Bayverse).
