## History

### Background

It all started after the events of the First Kraang Invasion, where life in New York City had seemed to have settled down with the Turtles believing that the Kraang were gone and were letting the glory of defeating them go to their heads. While April was forced to stay inside by her dad, Kirby out of fear that the Kraang were still around which the Turtles denied. However, the Kraang were still around and continued their partnership with Shredder and the Foot Clan. One night, the Kraang made an agreement with Shredder to deliver to him a shipment of Mutagen on a Kraang Stealth Ship. Which the Turtles discovered after intercepting a message from the Kraang with the Kraang Communication Orb they had but didn't know about the Mutagen. The Turtles tried to find it with help from April who got Kirby to help out as well without him even knowing it due to his paranoia. When they found the ship, they got onto it using the T-Rocket and their gliders. The Turtles fought off the Kraang on the ship who used a new weapon which was a gorilla-like robot suit called a Biotroid. During the fight, the Turtles discovered the Mutagen accidentally caused all the Mutagen canisters to fall out of the Kraang Stealth Ship and land all over the city. A canister even hit Kirby which mutated him into a giant deformed bat creature after he had touched some bats when the Mutagen landed on him. After the Turtles defeated the Biotroid and took care of the Stealth Ship, Kirby captured April so the Turtles came up with a plan to save her and catch Kirby by using their gliders and having Michelangelo dress up like a giant fly to act as bait for Kirby which the other Turtles convinced to be his superhero alter ego which called Turflytle. Which worked and the Turtles were able to rescue April and catch Kirby which Michelangelo named Kirby Bat at the warehouse. At first, April blamed herself for her father's mutation but when Michelangelo revealed to her that he and the other Turtles were the ones who dropped all the Mutagen, April got angry and blamed them for her father getting mutated. Then after Kirby Bat escaped, April told the Turtles she never wanted to see them again which made them all feel sad and guilty, especially Donatello. But because of the scattered Mutagen canister more mutants started to pop up around the city which the Turtles tried to control by collecting every single canister of Mutagen while at the same time, Donatello tried to find a cure for the mutations by making Retro-Mutagen which he hoped to use to cure Kirby and win April back. Meanwhile, April had made new friends who were a hockey-playing delinquent named Casey Jones whom April was tutoring for school, and a nerdy girl named Irma who was actually Kraang Subprime in disguise who had been sent by Kraang Prime to spy on April for the Kraang using a specialized Kraangdroid body that he stole and modified from the Utrom Council member, Rook.

As for Shredder, when he found out about the Turtles ruining his Mutagen supply from the Kraang he decided to expand the Foot Clan on his own by replacing the Foot Soldiers with robot ninjas called Foot Bots which were developed by the Kraang after the old Foot Soldiers had lost value with the Shredder for being easily defeated by the Turtles. Then he decided to go to Japan to recruit a new and powerful weapon and in his absence, he left Karai in charge of the Foot Clan. During that time, Karai had the Footbots attack the Turtles which forced them to retreat but the Footbots were able to capture Leonardo while the other Turtles escaped. Karai then came up with a plan to destroy the Turtles by using Leonardo as bait to lead the other Turtles into a trap and use all of the Turtles as bait for Splinter but the Turtles were able to defeat Karai and escape the Footbots. But during that time, Leonardo found out about what Karai thinks Master Splinter did to her mother then when he told Splinter about it, he revealed to Leonardo about Karai being his daughter, Miwa. Next, the Turtles went to TCRI to get a special centrifuge to help cure Michelangelo of his shellacne but it was in the hands of Baxter Stockman who was collecting Kraang technology from TCRI. When the Turtles tried to get it from him, Stockman was captured by Dogpound who wanted Stockman to make him human again after he got tired of his mutant form. Dogpound Took Stockman to his lab to make him human again using Mutagen which Stockman was planning to use to make his own Mutant army. Fish Face then arrived and wanted to be human again too then to make sure Stockman wouldn't betray them like last time, Dogpound placed a Mutagen collar on Stockman so in case he tried to double cross them they would puss the trigger for the collar and mutate Stockman. Then when Michelangelo snuck into the lab alone to get the centrifuge to cure his shellacne, he got caught and the resulting struggle caused Dogpound to fall into the tank of Mutagen which double-mutated him into a zombie wolf that Michelangelo named Rahzar. But the other Turtles arrived and together the Turtles defeated Rahzar, Fish Face, and Stockman and were able to get the centrifuge to make the antidote to cure Michelangelo of his shellacne. Then Karai had the Kraang construct a new and more powerful Footbot which Karai wanted to test it out by having it attack April who was still mad at the Turtles. Meanwhile, Donatello talked to April about how the Mutagen incident with her dad wasn't entirely their fault and that some things were just beyond their control but she just walked away. But when the Turtles found out about the new Footbot from the Kraang Communication Orb, they all rushed to the secret Kraang lab where it was being built to stop it. But while they were doing it, some Footbots attacked April at the ice rink along with Casey. April and Casey tried to fight them off on their own but they were outnumbered and April was chased by the Footbots. Meanwhile, The Turtles were able to find the secret Kraang lab and sneak into it where they found the new Footbot. They tried to shut it down but then Donatello got a call from April who needed help so he left the other Turtles and went to help April alone while the Other Turtles dealt with the Kraang who activated the new Footbot who fought off and defeated the Turtles then the Kraang sent it after April. Donatello was able to save April but had to face off against the Footbots while April faced Karai. Then when the new Footbot arrived, Karai ordered it to eliminate April. However, its programming was overridden and instead captured April to bring to the Kraang but Karai stopped it which made it attack her. Then the other Turtles arrived in the Shellraiser and defeated the new Footbot while Leonardo stopped Karai. Casey was also able to defeat all the Footbots at the ice rink himself. Later, April was able to forgive the Turtles and reconciled their friendship. Soon, Casey found out about the Turtles and became their friend too after helping protect their lair from some Footbots. Casey had also formed a friendly and tough relationship with Raphael, a funny relationship with Michelangelo, and a love rivalry with Donatello over April.

Then one night, the Turtles and April encountered a journalist named Jack Kurtzman who had been researching them and the Kraang for a year after doing a story on the scientists who were kidnapped by the Kraang. He revealed to them how the Kraang have been on Earth for centuries trying to terraform it and why they needed April to perfect the Mutagen to do it. But soon the Kraang arrived and attacked them hoping to capture Kurtzman and interrogate him but the Turtles, April, and Kurtzman were able to escape from the Kraang on the Shellraiser. After that, Kurtzman told the Turtles and April that the Kraang reset up their old base at TCRI and came up with a plan to have the Turtles infiltrate the place so they could erase all the data on April's DNA codes the Kraang had. The Turtles were able to sneak into the place along with April who wanted to help out. They were able to fight off the Kraang and get to the DNA area with help from a key card Kurtzman took from the Kraang and gave to them. There they found the Kraang telepathically communicating with Kraang Prime about perfecting the Mutagen and planning to invade the Earth again. But April accidentally gave away their position which resulted in the Kraang and a Ms. Campbell robot attacking the Turtles and April. They fought off the Kraang bur during the fight, April got captured then the Turtles were led into a trap by an April clone the Kraang created. But the Turtles were able to escape and found the main room where the Kraang made clones of April using her DNA while the real April was held prisoner by the Kraang to harvest more of her DNA. Donatello then tried to erase all of the data on April's DNA codes but then the Kraang arrived and sent out a giant defective April clone that Michelangelo named April Durp. But during the fight, Raphael tried to rescue the real April but got captured too and Donatello was able to wipe out all of the data on April's DNA codes. April was then able to use her psychic powers to defeat the Kraang and destroy April Durp. But while the Turtles and April tried to escape they ran into all of the April Clones which the Turtles and April were able to destroy. After that the Turtles and April were able to escape from TCRI with help from Kurtzman who vowed to help out the Turtles against the Kraang. But when Donatello looked at April's DNA at the lair, he revealed to April being a half-human half-alien mutant and that it was the source of her psychic powers. Afterwards, the Turtles discovered that the Kraang hunted down and captured Spider Bytez with help from Metelhead who was modified with an AI. Then the Turtles discovered a Kraang computer in an auto shop which Metelhead accidently blew up then he later discovered a hidden dimensional gateway in an old outhouse which Michelangelo was somehow only able to open. When the Turtles went through it they discovered a small pocket dimension Kraang prison where the Kraang have been keeping mutants they have captured and placed under their control. The Turtles and Metelhead were able to free all of the captured mutants and Metelhead was able to reopen the portal for all the mutants to escape through. Metelhead was also able to help the Turtles escape too by sacrificing himself in the process with the only surviving part of him being his head which deactivated. Later, Michelangelo got a new pet cat that April found which got mutated into ice cream during the Rat Wars that he named Ice Cream Kitty which had to be kept in the freezer.

Soon afterwards, the Turtles started to investigate strange earthquakes that had been happening frequently throughout the city which Donatello claimed was to be caused by machinery which Raphael believed was caused by the Kraang. Master Splinter also told the other Turtles about Karai being his daughter, Miwa. Meanwhile, Shredder had returned from Japan and brought back a new a powerful weapon which was a mutant Tiger assassin named Tiger Claw who had been mutated by the Kraang years ago when he was a kid and had been recruited into the Foot Clan as Shredder's new second-in-command with his first mission being to capture Splinter and the Turtles. Meanwhile, April and Casey discovered the Kraang walking into a portal where April and Casey were able to take down one of them and get the small device that was projecting the portal. They then took the device to the Turtles and they all through the portal to see if it was behind the earthquakes but the earthquakes soon happened again and caused the portal to turn off. Which trapped the Turtles, April, and Casey on the other side which was another dimension that had many portals that led to other dimensions. There they discovered a portal that led to Dimension X but some Kraang arrived through it which the Turtles, April, and Casey fought off but during the skirmish, Leonardo, Raphael, and Michelangelo got blasted back to Earth leaving Donatello, April, and Casey to deal with the Kraang. They were soon confronted by Tiger Claw who attacked them and tried to get them to summon Splinter to lead him into a trap for the Foot Clan. Meanwhile, Donatello, April, and Casey were able to beat the Kraang and discovered through another portal to Dimension X that the Kraang were herding Kraathatrogons through a portal to Earth then when the Kraang spotted them, Donatello, April, and Casey were taken prisoner by the Kraang who took them back to Earth in the sewers to be fed to the Kraathatrogons. But they were able to escape from the Kraang and discovered that the source of the earthquakes was cause by the Kraang bring the Kraathatrogons to Earth to be milked of Mutagen but when the Kraang found them they sent a Kraathatrogon after them. The Kraathatrogon chased them through the subways tunnels but Casey got eaten by it, forcing Donatello and April to get help from Kurtzman about the Kraathatrogon. He told them that the Kraathatrogons worms the Kraang were bringing were only children and that the adults can grow really big. Then Donatello got an idea to beat the Kraathatrogons and get Casey back using salt who called them telling them that he was still alive but stuck inside the Kraathatrogon. Donatello and April then went back in the subway tunnels, and were able to rescue Casey from the Kraathatogon by using the salt to barf him out. But found out that the Kraang were herding an even bigger Kraathatrogon that could destroy the city so Donatello came up with a plan to have April and Casey create a diversion by fighting off the Kraang so he could reverse the portal's polarity and keep the Kraathatrogon from coming through. But the Kraang released another Kraathatrogon to attack them but April was able to tame it by riding on it and used it antennae to guide it. Back in New York, Tiger Claw forces Leonardo to call in Splinter for help who came and fought off Tiger Claw but was then poisoned and captured by the Foot Claw. When Karai arrived, Leonardo tried to convince her that Splinter was her true father but she didn't believe him and tried to attack him but was stopped by Tiger Claw because Shredder wanted the Turtles alive so he could destroy them himself. But Splinter was able to free Leonardo, Raphael, and Michelangelo forcing them to escape and come back for Splinter later. After they heal up, Leonardo, Raphael, and Michelangelo go to Shredder's lair to rescue Splinter but also fell into another trap by the Foot Clan. But they were able to rescue Splinter from Shredder with the Foot Clan chasing after them. When the Foot Clan caught up, the Turtles fought them off until Splinter heeled up from the poison and fought alongside the Turtles. During the fight, Leonardo still tried to convince Karai that Splinter was her true father but suddenly, another earthquake hit and out of the ground came the Kraathatrogon that April and Casey were riding which ate Tiger Claw. Then Donatello was able to revers the portal's polarity which sucked both the Kraang and the Kraathatrogons back to Dimension X including the one that ate Tiger Claw. After that, the Turtles, Splinter, April, Casey regrouped and told each other what they all went through while Karai overheard them talking about her being Splinter's daughter. After that, Donatello was able to create Retro-Mutagen using April's DNA and ten canisters of Mutagen which was used it to cure April's father, Kirby Bat and change him back into Kirby. But Stockman was mutated into a fly by Shredder for failing him too many times and became known as Stockman-Fly.

Raphael and Casey then started working together to take down the Kraang who were stealing plutonium but found out someone else took down the Kraang and stole the plutonium that they stole. When they told the other Turtles about they all split up to find out who was behind. Eventually, Raphael and Casey discovered that the culprits were Raphael's pet turtle, Spike who was mutated into a giant turtle warrior named Slash that ounce tried to destroy the Turtles and the Newtralizer who teamed up with Slash to destroy the Kraang at any cost when Slash got captured by them and was freed by the Newtralizer. They also used the plutonium the Kraang stole to powerup their teleporters so they could find the Kraang and escape undetected. During one of their attacks on the Kraang, Slash the Newtralizer found out that the Kraang were going to test out a new weapon called a Kraang Walker at the docks. Which the Turtles were able to find from a Spy-Roach Donatello placed on Slash while they were fighting him and the Newtralizer. However, Newtralizer wanted to use the weapon to not only wipe out the Kraang but the whole city as well. When the Kraang bring the Kraang Walker, Slash and the Newtraliser attacked them along with the Turtles who tried to stop them. During the fight, Newtralizer took control of the Kraang Walker and used it to attack the Kraang and the Turtles which put Slash in danger until Raphael saved him. When Slash tried to reason with Newtraliser, he claimed he didn't care so Slash turned on Newtralizer to try and stop him from destroying the Turtles. Then Casey was able to stop the Kraang Walker by blowing it up with one of his exploding pucks but the Newtralizer was able to escape it just in the nick of time. After that, Slash leaves to find his own path while the Turtles and Casey head back to the lair thinking that the Newtralizer was gone but he survived and had gained new electrical powers but wouldn't be seen again until the Invasion of Dregg. Later, Tiger Claw returned to Earth and Shredder after fighting through other Dimensions for months trying to get back and lost an eye in the process. Together, he and Karai came up with a plan to destroy Splinter and the Turtles by having Karai pretend to defect the Foot Clan due to believing them about Master Splinter being her real father so Tiger Claw could come to the Turtles' lair and destroy them. But when Splinter showed Karai photos of him and her mother, Tang Shen back when he was human she truly began to realize the truth. She then helped the Turtles beat Tiger Claw but got captured by Tiger Claw and imprisoned by the Shredder in the process who told her the truth about Splinter being her true father. After that, the Turtles fought against the Kraang again at a Kraang base who were planning to use a machine to switch minds with the Earth's leaders so they can terraform the planet which the Kraang called Plan 10 and tested it out by switch the minds of a man and pigeon. The Turtles were able to stop the Kraang and switch both the man and pigeon's minds back but in the process, Raphael got his mind switch with a Kraang and was taken to the Technodrome under the ocean. Where Raphael discovered that the Kraang were planning to invade the Earth again soon and use a Kraang Communication Orb on the Technodrome to contact the other Turtles for help. So they along with April and Casey went to the Technodrome in the Turtle Sub and took the Kraang in Raphael's body with them. But soon the Kraang on the Technodrome were onto Raphael so he escaped from the Norman Kraangdroid and hid in another Kraangdroid. Then when the other Turtles, April, and Casey arrived on the Technodrome they were confronted by the Kraang but Rapheal convinced the Kraang to spare them and claiming that they would be used for mind switching. When they all got to the mind switching machine, the Turtles, April, and Casey fought off the Kraang and used the machine to switch Raphael's mind back to his body. Then the Turtles, April, and Casey all escaped the Technodrome, damaged it, and went back to the lair where Donatello came up with a plan to fight the Kraang when the invasion comes by building the Turtle Mech.

However, the Turtles were able to save Karai from the the Foot Clan and reunited her with Master Splinter who told her the truth about what happened between him and the Shredder and her mother. But then she went back to the Foot Clan to get revenge of Shredder which he anticipated which was why he let the Turtles rescued her. He then took Karai to Stockman's lab where he planned to use her as bait to lure Splinter and the Turtles into a trap where he would drop the Turtles in Mutagen and mutate them into mindless serpents that would attack Splinter. But during the skirmish between Splinter, the Turtles, and Shredder, Karai feel into the Mutagen and was mutated into a snake who later went into hiding which devastated Splinter and angered Shredder. Then one day, the Turtles got a message on the Kraang Communication Orb from their old friend, Leatherhead. Who had been in Dimension X fighting off the Kraang for decades due to the dimensional time differences in Dimension X. He warned the Turtles that the Kraang have finally perfected the Mutagen and that they're ready to invade Earth. So Michelangelo went thorough the Kraang portal that Donatello had to Dimension X equipped with one of Donatello's air filtration units so he could breathe in Dimension X then the other Turtles followed him also equipped with air filtration units. They tried to go to a Kraang base in Dimension X but on the way they found Michelangelo who had become a Dimension X survivor after being there for months due to the dimensional time differences in Dimension X. The Turtles then went the Kraang base where the Kraang were keeping Leatherhead but ran into the lava rock monsters Traag and Granitor which Michelangelo was able to defeat. The Turtles then snuck into the Kraang base and discovered that the Kraang have indeed perfect the Mutagen to terraform the Earth and everything on it into another Dimension X including the people. Then after they rescued Leatherhead they tried to escape back to Earth and discovered the army of Kraang Soldiers who will invade the Earth through Kraang portals. So the Turtles and Leatherhead were able to stop the Kraang by fighting them off, shutting down all but one of the portals, blowing up the Kraang base, and escaping back to Earth. Michelangelo even managed to get a Kraang power cell for Donatello to power the Turtle Mech. But then one night, Shredder made a deal with Kraang Prime that the Kraang would help Shredder destroy Master Splinter and the Turtles and mutate Karai back to normal ounce Shredder found her and in return Shredder would help the Kraang invade the Earth starting with New York City again.

### The Battle

The next day while its snowing, Irma talks with April about wanting to meet the Turtles which April told Irma were her secret friends when suddenly some Footbots arrive and chase both April and Irma. Meanwhile, Raphael and Casey search for Karai while the rest of the Turtles plan on dealing with the Kraang when they invade by using the Turtle Mech which Donatello had just finished. However, Leonardo doubts that the Turtle Mech is ready to be used believing that it might damage the city and states that they should leave the city and set up a base somewhere outside it. This leads to an argument between Leonardo and Donatello about leadership until Splinter gets them to stop. Back in the city, April and Irma escape the Footbots by going into the sewers where April takes Irma to the lair. Back in the lair, April brings Irma to it and when Irma sees that Turtles she reveals herself as Kraang Subprime in a powerful robot body and starts attacking the Turtles, April, and Splinter. He also declares that by discovering the Turtles' lair was the key needed to begins the invasion. By sending out a signal that alerts an army of Kraang soldiers who come to the lair through several Kraang portals also attack the Turtles, April, and Splinter. The Turtles and Splinter fight off Kraang Subprime and the Kraang soldiers during which, Kraang Subprime attacks Michelangelo and is about to hurt him using saws when Michelangelo uses a bagel cutter to cut off the head to Kraang Subprime's Irma Bot. But the head gets up on it's own and starts attacking Michelangelo and destroys parts of the lair. Kraang Subprime then tries to capture Splinter but he fights off Kraang Subprime then he gives the Turtles their weapons and tells both them and April to escape while he deals with the Kraang alone and tries to hold them off. The Turtles and April try to get to the Shellraiser but Kraang Subprime stops them by shooting a missile at it which forces the Turtles and April to try and escape by foot. While escaping they come across two path with one leading to the Turtle mech and the other leading to the city. Donatello wants to go to the Turtle Mech to fight the Kraang but Leonardo wants to go to the city to find Raphael and Casey first. This starts another argument between them which ends when a Kraang portal appears between them and more Kraang soldiers arrive. This separates Leonardo from Donatello, Michelangelo, and April who tells them to run while he leads the Kraang away from them. Meanwhile, Raphael spots Karai and tells Casey about when some police officers arrive to arrest Casey for loitering. But suddenly, Raphael notices Kraang portals opening up and an army of Kraang soldiers marching down the city while Casey fights the police officers and discovers that they are actually Kraang in disguise so Raphael and Casey try to escape back to the lair. They fight off the Kraang soldiers in the city while trying to get to the lair but soon come across a Kraang Walker that attacks them. Donatello, Michelangelo, and April manage to get out of the sewers and into the city with Donatello blaming himself for them losing Leonardo. But then more Kraang soliders arrive and attack them which they manage to hide from then go to find Kirby, Raphael, and Casey and try to get out of the city. Meanwhile, Raphael and Casey escape from the Kraang Walker but then a big Kraang portal opens up and a Kraang Stealth Ship arrives then they get a call from Michelangelo tell them to meet up at April's apartment but soon the Kraang Stealth Ship starts attacking them. Back in the sewers, the Kraang search for the Turtles to bring them to Shredder which Leonardo avoids while Donatello, Michelangelo and April rest and take shelter at April's apartment with Kirby worrying about the Kraang invading. Then they watch through the window as the Kraang attack the city with Stealth Ships and Walkers. Shredder and the Foot Clan then go out into the city and watch it all when Rahzar appears and tells Shredder about the Kraang leading Leonardo strait to them who Shredder prepares to fight. Back in the lair, Splinter continues to fight off Kraang Subprime and is able to defeat him by destroying his Irma Bot and crushing him with some rubble then Splinter goes to find the Turtles. Afterwards, Leonardo makes it out of the sewers and is attack by Footbots which he is able to defeat them. Meanwhile, Raphael and Casey almost make it to April's apartment but then Kraang Prime arrives through a Kraang Portal and starts using Mutagen to terraform the city which makes crystals grow out of the ground and turns the people into Kraang mutants.

Kraang Prime then starts chasing Raphael and Casey and tries to turn them into Kraang mutants too. But the a military group called the Earth Protection Force arrives and starts fighting Kraang Prime which distracts him enough for Raphael and Casey to get away from him. Meanwhile, Leonardo continues to fight more Footbots and starts to get tired which is part of Shredder's plan. When Leonardo gets exhausted from fighting the Footbots, Shredder sends out Rahzar, Fish Face, and Tiger Claw to finish him but Leonardo beats them all until Shredder arrives and injures Leonardo with just one attack. When Shredder learns that the rest of the Turles are at April's apartment, he orders Rahzar, Fish Face, and Tiger Claw to bait them out using Leonardo and destroy them. Raphael and Casey then arrive at April's apartment and warn Donatello, Michelangelo, and April about Kraang Prime coming. Suddenly, Leonardo is thrown into the apartment through the window badly injured much to everyone's shock. Soon Footbots invade the place, forcing everyone to escape outside and evade the Foot Clan to Kirby's old Party Wagon. Then Kraang Prime arrives and turns Kirby into a Kraang Mutant but the Turtles, April, and Casey are able to get into the Party Wagon and drive away from Kraang Prime. Back in the sewers, Splinter evades the Kraang to look for the Turtles but soon the Kraang finds and attacks him but is soon saved by Leatherhead who helps Splinter find the Turtles. When Splinter gets to the surface, Shredder confronts him and they start to fight each other. Shredder is able to pin Splinter down with metal pipes but the Leatherhead appears and fights off Shredder but Shredder is able to defeat Leatherhead by knocking him into the ocean. Suddenly, Splinter bursts out of the pipes and attacks Shredder by plunging him into the sewers. The Turtles, April, and Casey stop at a place and then split up with Donatello, Raphael, Michelangelo, and April heading back to the lair to find Master Splinter while Casey goes to look for his family in the Party Wagon and takes Leonardo with who is still too injured to move. When they get to the lair, they find Master Splinter gone and the lair a mess then Donatello tells Raphael and Michelangelo that they will take one meaningful thing with them, find Master Splinter, and then get out of the city. With Raphael taking a photo of Slash back when he was Spike, Donatello taking his medical supplies, and Michelangelo taking Ice Cream Kitty and some pizzas. Suddenly, April gets a psychic sense of Master Splinter fighting Shredder close by and tells the Turtles about it. They all go to find Splinter only to helplessly watch as Shredder defeats Splinter and throws him down a sewer drain. After Shredder leaves, the Turtles and April decide to get back at him by taking the Turtle Mech and marching it to his lair while fighting off the Kraang. But when they get to Shredder's lair they are attacked by Kraang Prime so they fight him off using the Turtle Mech but Kraang Prime proves to be too strong. Until the Turtles and April are able to defeat Kraang Prime by using the Turtle Mech to tab into the city's power grid and shock Kraang Prime which causes both Kraang Prime's Kraangdroid body to short out and deactivate and all of New York City to go dark but in the process is also uses up the Turtle Mech's power. As the Turtles and April celebrate their victory, Kraang Prime emerges from his Kraangdroid body and tries to attack them but April uses her psychic powers against Kraang Prime then Casey returns and rams the Party Wagon right into Kraang Prime before he could get them. The Turtles and April then get into the Party Wagon and they all drive away from the city as the Kraang have now completely taken it over and transformed most of the people into Kraang mutants.

### Aftermath

As the Turtles, April, and Casey drive away from the city while tending to an injured Leonardo, Donatello stated that if they had just left the city when Leonardo told them the Kraang would never have found the lair and started the invasion. April then suggested that they go to their her family's old farmhouse to be safe from the Kraang while Casey revealed that he couldn't find his family and thinks that they got turned into Kraang mutants too. Meanwhile, Master Splinter was saved by Karai in her snake form. The Turtles, April, and Casey stayed at the farmhouse for months where they face crazy and scary new enemies and trained themselves for when they had to go back to stop the Kraang who had prevented anyone from getting in or out of the city and fooled the rest of the world into thinking everything seemed fine by taking control of both the media and military. Eventually, Leonardo was able to heal up and the Turtles were ready to go back to save the city and all the people in the Battle for New York. But Kraang Prime wouldn't be seen again until the Triceraton Invasion of 2012 where he would eventually meet his end.
