Teenage Mutant Ninja Turtles

When the turtles witness the kidnapping of April O'Neil and her father Kirby by the Kraang, Donnie urges them to rescue the duo.

The turtles locate the Kraang hideout where April and Kirby are being held prisoner, but freeing them means fighting Snakeweed, a giant mutant plant.

The turtles try to rescue an obnoxious New Yorker who has videotaped and threatened to expose them, but he is mutated into a spider villain.

To prove the boys can be friends with humans, Mikey goes online to befriend a martial artist — who turns out to be a pupil of Shredder's.

Grounded by Splinter, the turtles sneak out anyway and lose their new T-Pod, which a bitter former TCRI employee uses for his own vengeful ambitions.

Donnie creates a remote-controlled robotic turtle fighter named Metalhead to take his place, but the Kraang are able to seize control of it.

The case of a missing neurochemist leads Donnie and April to a psychic monkey, the bizarre result of experiments using mutagen and monkey DNA.

After the turtles battle the Purple Dragons at a noodle shop, Shredder sends the Foot Clan after them led by Xever Montes, a brutal street fighter.

The turtles and April set out to rescue her father and stop the Kraang from detonating a mutagen weapon in the city, but Shredder surprises them.

Terrified of Shredder defeating the turtles, Splinter puts the team into round-the-clock training, which pays off when Shredder attacks the sewers.

The turtles are forced to split up into two teams when both the Purple Dragons and Stockman's MOUSERS launch separate attacks.

After the turtles rescue the surly mutant alligator Leatherhead and Mikey nurses him back to health, they discover he has the Kraang's power cell.

While letting an increasingly critical Raphael try leading the group, Leonardo meets a Foot named Karai, who tries to get him to switch sides.

The team must save New York and Splinter from the evil Dr. Victor Falco, who has been transformed into the powerful Rat King.

Leo and Raph fight over whether they can trust Karai, while the Kraang are drawn to April's high school science project, leading to a violent fight.

As the Kraang search for their power cell, the turtles meet a fan: a teenager with no combat skills who dresses up as "The Pulverizer" to fight crime.

The turtles discover the location of TCRI headquarters and break in to discover the Kraang's plan: to open a doorway to Dimension X and invade.

Donnie creates a roach that's really a spy camera to keep tabs on the Kraang lab, but the "spyroach" becomes mutated and goes after Raph.

Stockman and Shredder lure the turtles, along with Dogpound and Fishface, into a labyrinth of lethal traps and snares called the Maze of Doom.

With a Kraang invasion imminent, Karai offers a truce and access to new weapons from Shredder's arsenal, but can the turtles trust their new ally?

The turtles infiltrate a submerged Kraang base and capture a droid. When the Foot learns that April is key to the alien plot, Karai races to detain her.

Shredder learns about the mutagen weapon, while the turtles persuade the Pulverizer, who has been recruited by the Foot, to spy on the enemy for them.

Attacked by an enormous mutant Kraang wasp, the turtles slowly come under its toxic spell and will do anything to protect the wasp's surviving egg.

Trying to impress April, Donnie breaks into a secret Kraang prison by himself to rescue Kirby and faces a deadly detainee called the Newtralizer.

The turtles launch an assault on TCRI to shut down the portal and prevent the Kraang from bringing the Technodrome through the portal.

The turtles must enter the Technodrome and face Kraang Prime in order to save April. In battle against Shredder, Splinter recognizes a familiar face.
