Official Description

When the Turtles get word of the Kraang’s return, they realize there is an even bigger threat coming to Earth.


Part 1:

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.

Part 2:

As Mikey stares down the barrel of a Triceraton's plasma weapon and is about to be shot, a shuriken lodges into the Triceraton's gun, blowing it apart. We see that this shuriken was thrown by Splinter, who has arrived on the scene with reinforcements: the Mighty Mutanimals, now with two newly recruited members, Mondo Gecko and Muckman; and April. Everyone begins fighting, and Slash manages to use his mace to damage the timer on the Black Hole Generator, but this does not make it irreparable. Meanwhile, Bishop abandons his destroyed robot body and runs off in the middle of the fray, while Muckman, Pigeon Pete and Mondo are incapacitated by a few Triceratons. More Triceratons then beam down, one of them being Mozar, who removes Rockwell's psychic amplifier and traps him in a bubble-like object to contain him; the same is done to Slash, Leatherhead, and Casey. Mikey attacks Mozar, but Mozar grabs him and teleports with him back to where he came from: the Triceraton mothership. With the arrival of even more Triceratons and the odds overwhelming, Splinter, April, and the others reluctantly retreat without the Mutanimals and Casey.

Mikey and Mozar arrive in the Triceraton mothership. Mikey asks Mozar for clarification on why he is determined to destroy the Earth, to which Mozar replies that the Kraang want Earth as a hiding place where the Triceratons cannot detect them. To prevent the Kraang from claiming Earth and eluding the Triceratons, Mozar has found the simplest solution: to wipe out the planet. Mozar does not care about the humans' lives and refuses to get along with Mikey. Mikey then somehow manages to break out of his containment bubble but is quickly captured and told that he will be forced to endure the pain inflicted by the Psionic Extractor, a device that extracts one's knowledge.

Meanwhile, back on Earth, Splinter, the other three turtles and April collect themselves on a rooftop and discuss their predicament. Leo wants to go back to the square for the others while Raph wonders what's being done to Mikey up in the ship. Splinter wisely proclaims that stopping the Black Hole Generator is their main priority because the Earth is doomed if they don't. Donnie joins the conversation, saying that it may take the Triceratons a while to repair the Black Hole Generator's timer. Splinter instructs the Turtles to rescue Mikey as he and April ally themselves with someone more powerful than the Mutanimals to stop the Triceratons. April and Leo wonders who this is; and Splinter says that it is the Shredder.

Back on the mothership, Mikey is strapped down to a table and the Psionic Extractor device is described to him. It will purportedly extract all of his knowledge of the Earth and the Kraang, and in the process destroy his psyche. The device is then activated and instead of being painful to Mikey, it simply energizes him with feelings of euphoria. After the device is turned off, Mikey begs them to turn it on again and expresses how fun it was, much to Mozar's annoyance. It turns out that the only information extracted from Mikey's brain was his love of pizza. Agitated, Mozar demands that Mikey be eliminated. When Mikey is again about to be shot, he talks his way out of it by (truthfully) saying that he knows of Kraang bases in Dimension X.

Meanwhile, back on Earth, Splinter and April arrive at the Foot Headquarters and enter the Shredder's throne room, only to be ambushed and attacked by Tiger Claw, Bebop and Rocksteady before Shredder himself comes on the scene and stops Tiger Claw from killing Splinter, As Shredder demands to know why his enemy has come here, thinking that he came so he can kill him and claim his vengeance, Splinter straightforwardly asks Saki if he will help save the world or watch it be destroyed. Instead of answering this question, the Shredder asks Splinter what he has done with Karai, referring to the events of "The Fourfold Trap". Splinter replies that he and the Turtles searched for her but couldn't find her and came to the conclusion that she is alive but not in the city. While Shredder refuses to believe this and prepares to kill him, April assures him that Splinter is telling the truth, and appeals to his love for Karai, saying that if the Earth is destroyed, he will never see her again, and also believes that he should be a hero for a change if he still loves her. After brief hesitance, he begrudgingly agrees to help them stop the Triceratons.

Meanwhile, Leo, Raph, and Donnie find Mikey's Kraang Stealth Ship and enter it. They begin to fly in it toward the Triceraton mothership, which is located approximately halfway between the Earth and the Moon. As they approach their destination, Donnie activates the Stealth Ship's cloaking device to avoid being detected. Unfortunately, the Triceratons detect them anyway, and Mozar deploys a squadron of Triceraton fighters to take them down. The Turtles manage to fight their way past these ships and proceed to approach their destination when the Triceraton mothership turns on its side and fires a plasma beam in their direction. Just before the Stealth Ship is vaporized, Donnie uses a teleporter that he snagged from a Triceraton earlier to transport himself and his brothers to the opposing ship. There, the three Turtles are greeted by a captive Mikey, Mozar and the other Triceratons.

Back on Earth, the Triceratons march through the city, destroying most everything in their path. Bebop then appears on a rooftop, distracting a Triceraton so that Rocksteady can take him down. Shredder then attacks another Triceraton, defeating him. Splinter tells them that they should remain stealthy. Following this, Splinter, April, Shredder, Tiger Claw, Bebop, Rocksteady, Rahzar and Fishface proceed to Washington Square and hide behind cover upon arrival, and witness a Triceraton technician finish repairing the timer for the Black Hole Generator, resulting in the countdown continuing from where it temporarily stopped. April and Tiger Claw suggest that they should come with a plan fast, but when Triceraton reinforcements arrive to double the number of troops to defend the Black Hole Generator before the countdowns ends, they decide to launch an all-out attack on them without even formulating a plan.

Back on the mothership, Donnie tries to appeal to Mozar's better nature by informing him that the Earth has potential. However, Mozar implies that humans treat the Earth just as bad as the Kraang, and allows everything to proceed as planned by polluting the planet without even using Mutagen. Mozar then orders the Turtles to be thrown out of the airlock. However, before this could be done, Leo, in silent fury, warns Mozar one last time to leave the Earth alone or be destroyed. In spite of this, Mozar remains unimpressed, and thus, Leo snatches a portable prison cell from a Triceraton soldier and hurls it at the dome of the mothership, penetrating it and creating a big hole, sucking multiple unfortunate Triceraton soldiers aboard the ship out into space. The Turtles are about to be sucked out into space as well, but fortunately, with the teleporter Donnie snagged, they were able to teleport back to Earth.

After teleporting back to New York City, the Turtles realize they are near Washington Square when fighting erupts as Splinter, April, Shredder and the Foot Clan battle the Triceratons guarding the Black Hole Generator. April goes to free Casey, and after doing so, the pair go to free the Mutanimals, but Slash and Rockwell inform them that they must destroy the Black Hole Generator first, given that they are running out of time. The Turtles join the fight to aid in battling the Triceratons. As everyone is busy battling the Triceratons, the repaired timer on the Black Hole Generator rapidly ticks closer to zero, and Splinter, realizing that he and Shredder are the closest ones near the Black Hole Generator and the only ones who can stop it due to not being preoccupied, calls for Shredder to help him stop the Black Hole Generator before it's too late. Splinter runs toward the timer of the Black Hole Generator to deactivate it, though he is unaware that Shredder is following him, and before Splinter can shut down the timer before the countdown ends, tragedy strikes. Shredder, wanting to seize his chance to obtain his revenge by ending his personal war with Splinter once and for all, impales Splinter through his chest with one swift strike in cold blood, much to the horror of the Turtles, April and Casey. After Splinter falls to the ground gravely wounded as Shredder stands over him triumphant, the Turtles scream out in despair over the death of their adoptive father, and rush over to him. April, out of malicious spite, sheer anger and pure grief, screams and unleashes a telepathic burst wave of psychic energy, knocking Shredder away from her dying mentor, with the Kuro Kabuto being flung from his head as a result. But it is already too late, as the timer of the Black Hole Generator hits zero once Splinter succumbs to his mortal injury and the countdown ends, ensuring doomsday for the entire Earth.

The Black Hole Generator activates and ascends into the sky, and slowly starts to enlarge as a black hole is opened, preparing to devour the entire Earth, along with everyone and everything inhabiting it. All of the Triceraton soldiers on the planet quickly beam themselves back to the Triceraton mothership as Bebop yells out in horror that they are all doomed with Rocksteady telling him to hold him close, embracing each other in terror seconds before being lifted into the sky by the black hole as Fishface holds onto a tree with Rahzar holding onto one of his mechanical legs, resulting in the former kicking the latter off of him with his other mechanical leg before suddenly losing his grip mere seconds afterwards, and they too are dragged into the sky as Bebop and Rocksteady are devoured by the black hole, followed by Rahzar and Fishface themselves. Having witnessed the death of his fellow hench-mutants, Tiger Claw angrily calls out Shredder on what he has done in condemning the Earth to annihilation while holding onto a tree, but the unmasked Saki holds no guilt or remorse for his actions as he holds onto a rocky bench, saying that he doesn't care if the Earth and all of humanity, including himself and Tiger Claw, are about be destroyed, because in his mind, with Splinter dead, he has finally won and gained his vengeance. The Turtles, April and Casey run over to Splinter's lifeless body and mourn his loss, emotionally shattered and saddened, with a heartbroken Mikey wrapping his arms around his body and beginning to break down crying. As the black hole continues to grow all over New York City, city alarms, such as civil defense sirens, start to go off as it proves to be a terrifying sight for the population of the city, and dozens of humans, animals, vehicles, buildings, structures and objects, along with Splinter's body, Shredder, Tiger Claw, Bishop and the Mighty Mutanimals, start being rapidly pulled into the sky to be consumed by the black hole.

Luckily for the Turtles, April and Casey as they hold on for dear life, at the last possible minute, a mysterious white spaceship descends from outer space and lands near their position, and from a silhouettes distance, a mysterious white robot on board tells them to get on if they want to live as time runs out, and with no other choice, the gang quickly climb aboard before all of New York City, alongside the surrounding land and water, is torn from the planet surface and swallowed by the black hole. Their mission complete now that the Earth is doomed to destruction, the Triceraton mothership leaves the Solar System, teleporting away with Mozar and the Triceratons aboard chanting "Long live the Triceraton Empire!" as it does. The spaceship quickly departs the Earth as it slowly starts to crumble into a million pieces, but it gets caught in the black hole's powerful gravitational pull, but by switching to turbodrive, the spaceship is able to break free and fly off into space. As for the crumbled pieces of the Earth, they are all sucked into the black hole. And as the black hole disappears as a result of the Black Hole Generator itself returning to normal size and shutting off following the complete destruction of the Earth, there's an aftershock that sends a giant shockwave across space and hits the spaceship, causing everyone aboard to go through turbulence, but it then passes through and they all remain unharmed.

On board the ship, the gang stare at where the Earth once was (where there is now nothing but a cosmos of stardust and silence) completely shocked, horrified and devastated by the loss of Splinter, their families, their friends, their allies and the Earth itself. Their mysterious savior then tells them that watching their entire world vanish into the quantum singularity of a black hole is rather distressing, and offers them some hot cocoa as a way of comforting them. Mikey accepts a glass of cocoa and asks the mysterious figure who he is. He introduces himself as Professor Zayton Honeycutt, and explains to the gang that they are about to embark on a wondrous adventure, restoring hope in them. Casey takes one good look at the ship and can only voice his excitement saying how awesome this is as the ship rockets off, flying into the unknown of space.


Splinter's Wisdom

(to Shredder) "Our feud is meaningless in the face of this invasion.''


Annihilation Earth!/Transcript


  • There were originally going to be some scenes where Mikey questions Casey about his catchphrase Goongala!'. This idea was scrapped for unknown reasons.
  • These episodes were released a week early on the Nickelodeon website.
  • The Earth was destroyed along with everyone on the planet except for the Turtles, April, and Casey, as they were saved by the Fugitoid in his ship, the Ulixes.
  • Leatherhead and Rockwell's pose, seen seconds before the Earth was sucked into the black hole, was an homage to "The Creation of Adam", the most famous fresco painted by Michelangelo di Lodovico Buonarroti Simoni on the ceiling of the Sistine Chapel.
    • Ironically, the Creation of Adam symbolizes the beginning of life, while this moment in the episode is actually when all life on Earth comes to an end.
  • Originally, the writers were talking about ending this finale in fashion similar to season Four's "Earths Last Stand", except Splinter' would still die as he did in this episode. The following season would have been focusing on Leonardo and the turtles hunting Shredder down and killing him, while also defeating the Triceratons. Nickelodeon rejected the idea, reasoning that it is too "dark" for kids.
