Major Characters

Minor Characters


The Turtles, April, and Casey are driving in the Shell Raiser when Donnie notices that someone has been following them in a car for several blocks. As the vehicle pulls up next to them, they identify the driver as a Kraang wearing sunglasses. The team follows the Kraang into an alley where it mysteriously disappears. In this alley, there is a spray paint message on a dumpster telling the Turtles to come to a particular address. Increasing the mystery of this message is the bishop (chess piece) accompanying it.

The Turtles, April, and Casey arrive at the address that they were sent to, and Mikey realizes that it is the butcher shop that they fought Tiger Claw in a while back. Mikey leads the others in through a secret entrance, and they find the Kraang that is seemingly their enemy. Casey immediately attacks but is abruptly outmatched. All of the Turtles then attack, but they too are defeated and the Kraang tells them to hear him out. The Kraang introduces himself as Bishop, saying that he invented the Norman suit and that the other Kraang copied him. He also says that he is a member of the Utroms, who were initially part of the Kraang hive mind but broke away from it many centuries ago and have devoted themselves to peace. Although Bishop has broken his Utrom vow not to intervene in earthly matters, he notifies the Turtles that the Triceratons are coming armed with enough firepower to destroy the entire solar system. Leo doesn't believe this, as they stopped the beacon that Zog was going to use to summon the others, but Bishop assures him that they are in fact coming. To make matters worse, the Kraang have finally repaired the Techodrome that went down in the Hudson River and are about to invade with it once more. Bishop finally states that if the Triceratons arrive as the Technodrome rises, they will home in on Earth and vaporize it. April asks why the Kraang and Triceratons hate one another, to which Bishop responds that the two species have fought over Dimension X for millennia. The Kraang have used their technical savvy to fight their foe, while the Triceratons have employed the tactics of brute strength and cunning. In one noteworthy battle, the Kraang used a Black Hole Generator (the most powerful weapon in the known universe) to wipe out the Triceratons' entire homeworld. Only a single Triceraton fleet survived and they vowed vengeance, causing the war to continue.

In the sewer lair, Rockwell and Slash are asleep, recovering from the injuries that they sustained at the hands of Zog. Leatherhead is here as well, and Splinter reassures him that his friends will heal in time with rest. The Turtles and the others then arrive with Bishop and introduce him. Leatherhead attacks Bishop, but the Turtles stop him and confirm that Bishop is peaceful. In the living room, Leo lays out their plan for taking out the Technodrome. Raph, Donnie, Mikey, and Leatherhead will take the Turtle Sub to the Technodrome and infiltrate it with the goal of disabling it before it can launch. If it does launch, however, Leo and the others will take it out in the Turtle Blimp. Splinter wonders what is going on with the mention of the Technodrome, and Leo responds that the whole world is at stake and that only they can save it. Splinter agrees, telling his sons and the others to carry on with their mission and that he will stay close to the cheese phone in case they need assistance.

In the Hudson, Kraang Prime and Kraang Subprime have finished repairing the Technodrome. Raph and the others in the Turtle Sub arrive and manage to infiltrate the Technodrome, but Mikey accidentally sets off an alarm. Meanwhile, the Technodrome launches to the dismay of those in the Turtle Blimp above. Leo tells Raph that he has two minutes to bring down the craft, to which Raph angrily responds that he will. However, he and the others in the Technodrome are then captured and forced to raise their arms in surrender. The Turtle Blimp, with explosives attached to it, rams into the Technodrome, which doesn't bring the Kraang hovercraft down but creates a hole in it that allows Leo, April, Casey, and Bishop inside with Turtle Gliders. Raph, Donnie, Mikey, and Leatherhead are brought before Kraang Prime, who tells them that they are about to witness yet another invasion of Earth. The Technodrome then detects something on a scanner, however, which turns out to be a Triceraton ship closing in on Earth. The leader, Captain Mozar, broadcasts a message to citizens around the world, stating that their planet is infested with Kraang and that the Triceratons plan to eliminate them by annihilating the entire Earth. After defeating Kraang Subprime, Bishop leads the others to a hangar with Stealth Ships in it, and the team splits up, taking three ships with two team members in each. In the first ship are Leo and Raph, in the second ship are Mikey and Casey, and in the third are Donnie and April. Bishop and Leatherhead manage to make it safely down to the Hudson.

The Turtles, April, and Casey pursue a group of Triceratons in aircraft and realize that they are not only targeting the Technodrome but heading for the city. The Triceratons eventually manage to hit Donnie and April's ship with a laser, sending them falling into Coney Island where Bishop and Leatherhead greet them. In the Triceratons' mother ship in space, Mozar receives a message from his underling, who tells him that the Technodrome is on target. Mozar tells him to destroy it and then proceed to do the same to the world. Triceratons battling the Technodrome immediately clear, and the ship above powers up, blasting a plasma beam right into the Technodrome and blowing it to bits. The blast is powerful enough to send Leo and Raph's ship falling to the ocean. The Stealth Ship floats on the surface, and Leo and Raph open a hatch on top of it. Leo then gets a call from Mikey, who informs him of a weapon being carried by several Triceraton aircraft. Casey believes that these Triceratons are headed to Washington Square. As Casey and Mikey approach the aircraft, they hit a force field and fall into the city, fortunately coming to a halt between two buildings. Leo calls April, telling her and Leatherhead to gather as many allies as they can and that he'll text everyone a place to meet up.

The Triceratons arrive at Washington Square and beam down from their ships, setting up their weapon and attaching a timer to it. Leo, Raph, Donnie, and Bishop are already there, and Bishop identifies the weapon as a Black Hole Generator. Mikey and Casey then arrive when Donnie notices that the Triceratons are draining the city's energy supply to activate the timer on their weapon. The Turtles, Casey, and Bishop are forced to battle the Triceratons and initially fare well but are soon overcome one by one, with Bishop's robot body being shot repeatedly. All alone, Michelangelo is about to be shot as well.


  • When Bishop introduces himself as the inventor of the Normans and inhabiting the original Norman suit, this plot point is very similar to a certain plot point in the film Alien³, involving a different character of the same name. In that film, the protagonist Ellen Ripley deactivates her severely-damaged android friend Bishop as an act of mercy. But near the end, Ripley encounters "Bishop" again, only to find out this person she's meeting is human, and the original inventor of the Bishop model androids made in his own likeness.
  • Roseanne Barr did not reprise her role as Kraang Prime. In this episode, Kraang Prime is voiced by Rachel Butera.
  • This episode marks the final appearance of Kraang Prime.
