At night, Shredder was currently in his lair once more, he was going through the memories of the times he raised her, and then he remembered the scene of her being mutated into a snake mutant, Splinter got away with the turtles, while Karai's whereabouts are unknown.
"Master Shredder," Tigerclaw spoke as Shredder looked down and saw him and Kitsune kneeling before him, "The hour goes late. Have you made your decision?" Tigerclaw asked.
Shredder hummed, "Hmm, they are dangerous allies, but they have provided us with much technology, asking for little in return." he said in thought.
"They will betray us, you know this." Kitsune warned, "They care nothing for the human race." She stated. "Even if we help them, how can we be sure they won't betray us once they have what they desire?"
Shredder simply narrowed his eyes, "They won't betray us…not before we destroy them first, now leave me." he ordered as the two Foot loyalist left the throne Room. The Kraang projector then rose up next to Shredder and projected the image of a certain Kraang. "Kraang Prime." He said to the leader of the aliens.
"One called Shredder," Kraang Prime replied back, "Kraang must have your decision."
"If I help you, will you uphold your end of the bargain?" Shredder asked with a brow.
"Kraang will deliver the ones called Splinter and the turtles." Kraang Prime replied.
"And once I find Karai, you will use the girl, Robyn O'Neil, to turn her back to normal?" Shredder asked a little hopefully.
"Kraang agrees to this." Kraang Prime confirmed. "But in return, you must help Kraang conquer the city known as New York! And then.. the world!" He said maliciously.
Shredder was silent for a moment before he gave a malicious look back, "Then consider the Foot, your allies," He said as Kraang Prime, "Once your little infiltrator has the last piece of the puzzle, the Turtles and all who stand with them shall meet their end!" He declared before he and Kraang Prime howled with evil laughter.
At sunrise, snow was falling down while the O'Neil sisters and Irma were walking the street. "It's just that, why don't you introduce me to your secret friends, girls? I don't get it?" Irma asked confused.
"One of these days Irma. They're really good um.. People." Robyn said nervously. "Just take your time."
"Anyway, what we wanna know is: How can you go out in this weather without a coat?" April asked referring to the snow.
"Eh, I hardly ever notice the cold." Irma said with a shrug. "But seriously if we're friends, friends should introduce friends to friends and-" She screamed as Footbots suddenly surround them.
"Footbots!" April cried out.
"These aren't the kind of friends I meant!" Irma cried as Robyn pushed her and April forward.
"Move, girls! Move!" Robyn called as the three girls ran off with the Footbots chasing them. The girls tried to use their T-Phones to call the turtles, but some shurikens hit their phones. "No!"
"Who are these freaks!" Irma cried out.
"Doesn't matter! Run!" April yelled as the three kept running from the Footbots.
In another section of the city, Jenny, Keno and Raph are looking through some periscopes while searching the block. "Where are you, you little snake?" Jenny questioned.
"You'd think a giant white mutant snake should be easy to find." Keno said.
"You gotta be out there somewhere." Raph said with determination before the two heard cameras clicking as they looked down and saw Casey taking a picture on his phone as the two jumped down. "Casey! We're supposed to be looking for Miwa!" He reminded him.
"What are you even doing?" Jenny questioned with her arms crossed.
"Eh, i'm just taking a break peeping some awesome art." Casey said pointing to a graffiti he made of him and April. "Check it out, oh that is so metal!" He said looking at it.
"Yeah, great art there, Jones." Keno said dully. "Come on Case, Let's move." He said, ready to go back to the search.
"Uh hold on, guys, I gotta question for you. So um.. April ever talk about me, like ever?" Casey asked curiously.
"It doesn't matter. You know how Donnie feels about her." Raph replied, turning to him. "He's already split between her and Tal,"
"Yeah. Yeah, it's cool." Casey said with a small smile. "When you got that man, woman thing going on in a team, it just screws everything up. I'm not that into her anyway." He waved off.
"Then why did you made an art figure of her on the wall next to her?" Jenny questioned while gesturing to the graffiti of April on the wall.
"Uh, just something to get it out of my sister. It's a work in process." Casey said as he walked off.
"He's not over her." Keno said tiredly as they continued on.
In the lab, the rest of the turtles were in Donnie's lab while Donnie and Tal were inspecting their plans, Leo was pacing around, Mikey and Ames are eating pizza while Naomi, Vee and Olly stood around watching them and looking anxious. Donnie sat down to his laptop and groaned. "I'm so worried I can't even eat!" He said as he tossed his slice away and Mikey caught it.
"Me, too. Totally." Mikey said with his mouth full as he hate the slices.
"This whole invasion thing is so stressing," Olly said while rubbing his head. "I mean, it could happen at any moment."
"You have a right to be concerned," Splinter said as he walked into the lab. "The Kraang invasion is imminent. What plans have you devised to stop it?"
"We're working on it, Sensei." Vee said to him. "It's just an invasion this big, it's a little hard to figure out."
"From what we've experienced the Kraang have mind control devices, walkers, stealth ships, energy cannons, Bio-Droids, portable portals, Traag and Grantior and who knows what else," Leo listed out what they could expect from the invasion.
"One positive, with the damage we did to the Technodrome, it might not be ready for when Kraang attack," Naomi said optimistically.
"But with how the time flows faster in Dimenison X, their forces could be gearing up by this second." Olly said in concern. "And we still don't know when they'll strike."
"Which is why we gave you our latest invention." Tal said as she and Donnie brought out a board of the Turtle Mech. "The Turtle Mech!"
"It's fully armed with rockets, flame throwers, and an electro harpoon." Donnie listed out.
"With it powered by the Krang Crystal Mikey took from Dimension X, and some extra modifications we added with the Kraang and Foot tech we snagged, it's our best guarantee to stop a massive Kraang invasion army!" Tal continued with a smile.
"Or your money back." Donnie finished with a smirk.
"Giant robots are awesome! I vote Turtle Mech!" Mikey cheered in excitement.
"Same here! It's like Super Robo Mecha Force." Ames said with an excited smile.
"But that thing's not even ready!" Leo protested. "It could damage New York more than help it!"
"It's ready…" Donnie said before he thought for a moment before continuing. "...enough." He finished.
"There's gotta be another way." Leo said to them. "We need to establish a second base, outside the city."
"There is no time for that, Leo." Donnie said to him. "The Turtle Mech is solid. If I were leader, I-"
"But you're not leader, Donnie." Leo said firmly as he got in front of Donnie's face. "I am!"
"Oh, snap!" Mikey said with a snap of his fingers.
"Enough!" Splinter yelled, which made them turn to them. "Your egos fight one another, when we should be preparing to fight the Kraang." He reminded firmly.
"He's right, guys." Olly said as he steps in. "We shouldn't be arguing about our idea. We should be coming up with a plan to fight the Kraang, not at each other." He firmly said. "Let's just wait others to get back and then make our final decision as a group," He said as they all looked at eachother, wondering what plan they would take.
With the O'Neil sisters and Irma, they are still running away from the Footbots. "Faster, Irma! Move those little legs!" April yelled.
"I'm moving! I'm moving!" Irma cried.
"Move faster!" Robyn called as they then turned a corner. "This way!" She called as the three then enter an alley way before they reach a dead end.
"A dead end! It's the end, we're dead!" Irma cried out in fear.
"Not yet we're not." April said as they looked at the dumpster next o them. When the Footbots came, they saw no signs of them as they checked the dumpster and stabbed their swords in, not noticing them hiding behind three trash cans as they hid in another alley with a manhole next to them.
"That was close." Robyn whispered in relief as she looked at the manhole cover and then to April, seeing what she was thinking, "Oh no! Bad idea! Master Splinter made it clear, no more humans!" She said firmly.
"Well if you have any other ideas, I'm sure Shredder will be happy to here them," April said sarcastically.
Robyn thought for a moment before sighing in defeat, "Come on. This way." She said as April pulled Irma to the manhole as they opened it.
"You two are not serious?" Irma asked in disgust as the O'Neil sisters climbed down. "You are serious!" She cried.
"Just get down here, girl." Robyn said firmly as Irma slowly enter the manhole.
"Ugh! The smell is making my sinuses melt." Irma said in disgust as she climbed down.
In another part of the city, Jenny and Raph were on the rooftops keeping an eye out while Keno and Casey waited down in the alley, "See anything, Raph?" Jenny asked.
"I think-" Raph stopped when he saw something sitting on rooftops while coming out from behind a water tower, "I see her!" He said, spotting Miwa in her snake form.
"You found Miwa?!" Jenny asked as she snatched the periscope and looked ahead and she gasped. "You're right! She's there!" She said before looking down, "Casey, Keno we found-"
But then, they heard police sirens as they turned and saw a police car parked in front of the two boys as the officers came out. "Great." Casey muttered.
"Play cool, man." Keno whispered. "Hi officers, is there a problem?" He asked.
"You're loitering, kids." The first one said to them. "You know what that means?"
"Loitering? Seriously?" Casey asked in amusement. "Don't you got real criminals to bust? Or donut shop to go to?"
"We'll figure out a charge later, Casey Jones and Keno Andrada." The second officer said firmly, which surprised the two boys.
"Wait, how do you know our names?" Keno asked before they were grabbed, "Hey! I think there's been a misunderstanding here!"
"Let us go! We have our rights!" Casey yelled next.
Back in the lair, the others are exiting the lab as Donnie tried to reason with them. "Guys, we have nothing to worry about. The Turtle Mech is the only answer. Be reasonable." He said stubbornly.
"We are being reasonable. We need a second base, Donnie. Period." Leo said firmly.
"And where would we even put a second base?" Donnie questioned.
Leo tried to think of something before Vee spoke up, "What about our island? It's the only place the Kraang don't know much about, so we could probably hide out there until the Invasion begins," She suggested.
"And come back with reinforcements," Olly added.
"But we don't even know where Turtle Island is," Donnie reminded them.
"We're working on it, Donnie." Tal said to him. "After our father's eagle took Raph's Sai, they should be on their way now."
"But it might take some time for them to arrive." Naomi said in concern. "And time is a luxury we don't have." She added before the O'Neil sisters and Irma rushed in as Irma slipped and dropped her glasses.
"Guys, I know this looks bad," Robyn started regretfully as they all saw Irma.
"But, but.. footbots were after us and...Irma here is really good at keeping secrets and um..." April said nervously as Irma got her glasses.
"April, Robyn, you two have brought a stranger here?!" Splinter asked, upset at them.
"Um, don't worry Master Splinter, she's cool! Right, Irma?" April asked nervously and her eyes widened seeing them.
"T.. t.. turtles?!" Irma asked as she saw Mikey.
"What up dog?!" Mikey asked casually.
"Turtles.. rgh.." Irma said as her body looked to be twitching strangely.
"Yeah, saw that coming." Robyn said tiredly.
"Yeah, we get that alot." Olly said as Leo stepped forward and pushed Mikey aside.
"Miss, I know we look kind of different and all, but I promise, we're not gonna hurt you." Leo assured Irma.
"Yeah, we're friendlies." Ames said with a smile while Irma kept twitching, which made Robyn and April nervous as they backed away from her before Irma suddenly popped her head up with a metal neck. "Holy, Mother of Mutagen!" She yelled as she tossed a slice at Irma's head, which caused it to spin.
"Turtles! Turtles!" Irma said robotically like an alarm system. The Hamato Clan teens all screamed in horrified shock as Irma's body transformed into an advanced-looking Kraang exoskeleton, with heavy-duty arms, legs, weapons, and in the cockpit was a Kraang with a mouth similar to Kraang Prime, a cybernetic-scarred left eye and a purple mark under its right eye and it laughed evilly at them.
"Girls, you gotta pick your friends more carefully!" Mikey exclaimed as they all took ready stances as the Kraang kept laughing before he cracked his cybernetic knuckles.
"Oh my gosh! Irma was a-" April tried to say before the Kraang extended its claws and grabbed ahold of the arcade game.
"Kraang!" The Kraang finished, speaking in perfect English, as he tossed the arcade machine at them, which they barely dodged as they fell to the floor. "Lowly insects! Kneel before the genius of Kraang Subprime! Greatest Kraang spawn in all of Dimension X!" He said as he stepped closer to them. "The discovery of your Lair was the final component needed to launch full-scale invasion!" He declared as Kraang Portal started opening up around the lair.
"Oh no!" Tal said in horror as they saw portals all around us.
"Those Footbots were just herding us so that we would resort to showing the lair to him!" Robyn exclaimed in shock. "They tricked us!"
"They lured us into a trap!" Olly said in great worry.
On the surface, the two officers are still trying to get Keno and Casey into the car. "Back off of us, man!" Casey yelled.
"Get in that car now, punks!" The officer yelled while Jenny and Casey watches.
"Casey, what have you done?" Raph asked in concern.
"Why would they even care about loitering?" Jenny questioned. "They don't just stop because of that." She said before her and Raph saw something sparking up in the corner as thunder cracked as a Kraang Portal opened up, which made them gasp in horror as more portals opened up and Kraang droids marched out.
"The Kraang!" Raph said in dread.
"It's begun!" Jenny added as they looked down to Keno and Casey pushing the cops back.
"Give me that stick!" One of them yelled before Casey accidentally whacked him to the face.
"Casey!" Keno yelled out in shock.
"Oops!" Casey cringed, but then the officer he whacked frizz out as it revealed to be the Kraang using a hologram. "Whoa!"
"A Kraang droid!?" Keno said in shock before turning to the Officer holding him and saw he was a Kraang too, "They've already infiltrated! It's invasion time!" Keno said as he smacked the Kraang away.
Raph then jumped down and stab the second Kraang down as Jenny jumped down next to them.
"Guys, what's going on?" Casey asked before a big portal opened up behind them as more Kraang came through.
"Like Keno said, the invasion started!" Raph yelled in panic as the Kraang started firing. "Back to the lair!"
"We gotta warn the others!" Jenny called as they all started running to the nearest way home.
Unfortunately, they didn't know that the Lair was also under attack as Kraang droids and Footbots appeared from the portals as Splinter began to fight them off. "The signal was correct. Kraang has discovered the place of turtle hiding." One of them noted as they started firing while Splinter ran on the pipes on the ceiling while the others tried to fight them as Leo grab a dagger from the punching dummy before Subprime grab the Space Hero pinball machine and tossed it at him, which he and the others dodged.
"This is so mess up!" April yelled with a look as she took cover behind some pipes to avoid blaster shots. "My best friend for the past year was a Kraang?!" She questioned in disbelief.
"Fooled you! Fooled you all!" Subprime called in amusement as he gave another evil laugh.
Ames and Mikey were cornered in the kitchen as Droids and Foobots tried to fight them off, "We should've kept our weapons on us!" Ames called as she then tossed some pots and pans at them, knocking them down as Mikey spun on the table and kicked a Kraang back into a Foobot. But before they could charge at them, the freezer door opened and whack it down as Ice Cream Kitty raised her paw with a meow. "Thanks, Ice Cream Kitty." She said with a smile as she and Mikey shared a high-three with her.
"Aw yeah!" Mikey cheered before he was kicked by Subprime as he gave a laugh.
"Mikey!" Ames called as she avoided Subprimes saws before he grabbed her and drew the sawblades closer to her as she struggled to break free.
"Ames!" Mikey yelled out as he grabbed a bagel slicer and stab the mech in the head, causing it to drop Ames as it, "Ha! Bagel slicing slicer time robot!" Mikey declared with a smirk before the robot wobbled around, forcing them onto the table as Irma's head fell in front of them.
"Okay, that's creepy," Ames said as Irma's head grew spider legs and screeched at them, "And that's even worse!" She exclaimed before she and Mikey ran away as the girl head fired eye lasers slicing through the pipes.
"Destroy the Turtles! Wipe out the whole Lair!" Subprime called as he turned to Splinter. "But the rat and the Blonde O'Neil come with us!" He finished with a smirk.
"What?!" Robyn exclaimed as she kicked away a Kraang droid.
"They know your DNA can cure the mutagen!" Tal said before she punched a Footbot back. "They're trying to remove the only thing that can stop their Invasion!"
"Then let's make sure they don't get anywhere near Robyn!" Vee called as she grabbed two Kraang and threw them back.
Olly then kicked a Footbot down before he dodged a laser beam from Irma's head. "Can someone deal with that head, please?!" He called out.
"On it!" Mikey called as he tossed the head up and spin kick it, but it flew and bit Donnie on the leg when he kicked a Kraang.
"Ow! Ow! Ow! Ow!" Donnie yelled in pain as he tried to shake the head off his leg.
"Sorry, D!" Mikey quickly apologized before he rushed into his room and saw his nunchucks.
In the dojo, Splinter dodged a blaster fire as Subprime advanced towards him. "Take that, you filthy rat!" Subprime called as he did a kick and tried to punch Splinter, but he dodged them as he then brought out his buzzsaws.
In the streets above, Raph's group were still being chased by the Kraang as the whole city seemed to panicking, "Look out!" Jenny called as she kicked away a droid.
"Whoa! Crosstown traffic!" Casey called as he and Keno grab hold of the back of a car while Raph and Jenny jumped on the roof of one as they turned a corner where another portal opened and they jumped off.
Only to be blocked by a Kraang Walker that appeared from a corner, "What the Walker?!" Raph exclaimed as the Walker took aim at them.
"Oh, snap." Keno said nervously.
"Move it! Run!" Raph yelled as the four ran off while avoiding its lasers and crushing feet.
"There's too many of them, boys!" Jenny called as they kept running while avoiding the shots from the Walker. "And they're coming out of everywhere!"
"We'll never gonna make it back to the Lair!" Keno said as they rounded a corner.
"Just keep going! Keep going! Go! Go!" Raph called as they kept running.
In the lair, Mikey hit two droids with his nunchucks as he got out of his room and rejoined the fight as Leo came from a room while avoiding shots. But when Irma's head was about to tackle him, his sword pierced right through it and it fell down as Leo turned to Splinter. "Go! Escape!" Splinter called as he tossed the turtles their weapons. "I will hold them off!" He called as Subprime came from the dojo and the two got into a standstill.
"We're not leaving you!" Leo called as he grab his other sword from Irma's head.
"I have a plan. Go, now!" Splinter called while holding Subprime back.
"Everyone, to the Shellraiser!" Donnie called as they made a break for the exit.
Subprime pushed Splinter back and aimed his rocket launcher at them, "You'll go no where!" He declared launching three rockets at the heroes which they managed to dodge but instead hit the Shellraiser, causing it to fall over, badly damaged.
Donnie gasped in horror, "MY BABY!" He cried out and rushed to the wrecked vehicle and knelt down looking crushed.
"No time for mourning, Donnie!" Olly called as another missile was about to fire, but Splinter grab Subprime's arm and missed his shot as it hit the entrance, but Mikey was blown away from the explosion as he fell down. "We have to retreat, now!"
"Follow me!" Leo called as they all rushed down the subway tunnel while still hearing Splinter fighting Subprime.
In the sewers, the group are still running down the tunnels. "This way!" Leo called.
"Ugh! This is all my fault! I lead them straight to the lair!" April cried in guilt.
"Apri, you didn't know Irma was a Kraang in disguise," Robyn told her sister.
"She's right, April," Vee said to them. "You were only trying to help a friend in trouble."
"But did you see? There were Kraang Droids and Footbots attacking," Leo noted with a grim look, "If the Kraang and the Foot are working together, then that means not only do the Kraang know where the lair is but…" He trailed off as the others came to the same realization, too.
"Shredder knows where it is, too!" Mikey exclaimed in horror.
"If he has, all the more reason to move!" Olly called before they stopped into an intersection of two tunnels. "Oh boy. This could be a problem." He said uneasily.
"Which way would we go?" Naomi asked.
"Left! That would lead us to the Turtle Mech!" Donnie said while pointing to the left side of the tunnel.
"No! We need to find Raph, Jenny, Casey, and Keno first!" Leo said to him.
"We can find them in the mech!" Donnie insisted.
"It's too slow!" Leo yelled out as the two glared at each other.
"You're the one that's too slow!" Donnie retorted. "You're leading us into a disaster!"
"I'm doing what Splinter would want us to do." Leo exclaimed.
"Guys!" Olly yelled out, pushing them apart. "Now's not the time to argue over which plan we should go with!" He exclaimed. "We have to move and find the others before-!"
He was cut off when a portal opened up between them and Leo as more Kraang and Foot came out. "It is the one called the turtles." A Kraang said as they all started attacked, they tried to fight back but Donnie got blasted on his arm as he fell down with a yell.
"Donnie!" Tal yelled in worry and rushed to him.
"Booyakasha!" Mikey called as he, Ames, Naomi, Olly, and Vee started fighting the Footbots and Kraang that came towards them as more pressed on.
"Run! Take April, Robyn, and Donnie to safety!" Leo called as he blocked some shots and stabbed a Kraang with his swords and used the body as a shield. "I'll lead them away!"
"We can't leave you too, Leo!" Vee cried as she kicked down a few Footbots and used a Kraang Blaster to shoot them down as Leo sliced two of the droids' heads on his swords.
"Just do it!" Leo yelled as he used his swords to clang the heads together, which got the two robo groups' attention. "Come on, Kraang and Foot! This way! Whoo! Yeah! Follow me!" He called as he ran down the tunnel with the Foot and Kraang chasing after him. "Come on! Over here!" He called.
"Leo!" Vee cried out with her arm raised as Tal and April helped Donnie up.
"You heard, Leonardo." Naomi said to Vee. "Donnie is injured, and we have to get to safety before more of the enemy arrive."
"I don't like this." Mikey said in concern.
"None of us do, Mikey." Ames said as they climbed up the tunnel and walked through while Olly looked to where Leo went off to in concern.
Once at a nearby manhole, Olly looked overhead to see if it was safe to come out. "Coast is clear." He said before he saw a car rushing down as he quickly ducked as it ran past him. "Okay, now it's clear." He said as they all climbed out of the manhole.
"Ow! It hurts so bad!" Donnie cried as he clutched his arm from where the Kraang shot him.
Tal held his arm, "You'll be okay Donnie, I'll get you fixed up," She said softly with a smile.
Donnie gave a small smile while Vee started calling Leo. "Leo, you there? Come on, Hero Boy, poke your head out of your shell and pick up!" She pleaded turning to the others. "He's not picking up his T-Phone!" She cried in worry.
"Leo must've turned it off to avoid getting caught." Robyn summarizes with a concerned look.
"Ugh! It's my fault!" Donnie said in guilt. "Man, I shouldn't have argued with Leo! Now he's gone!"
"Easy, Donnie. You were just doing what you thought was the best way to fight the invasion." Olly said to him in assurance. "But that doesn't matter now. What matters is what we press on." He said as a portal opened up behind them. "And hide!" He said as they all hid behind a taxi as some Kraang marched out and rushed past them.
"I don't think they saw us." Robyn said to them.
"Leo was right. We should have left the city while we had a chance!" Donnie said in guilt.
"Not without our dad and the others!" April said with determination. "Come on, guys!"
"But what about Leo?" Vee asked in concern. "He's alone and could be fighting for his life."
Olly gave a serious look and nodded, "Alright, the rest of you head to the O'Neil apartment and wait for Raph and the others," he ordered.
"What about you, Oliver?" Naomi asked in concern.
"I'm going to find Leo and make sure he gets back okay." Olly said seriously.
"What?! You can't go in alone!" Naomi said in worry.
"Leo is out there behind chased by the Kraang, He needs my help." Olly said to her while holding her shoulders. "Once I find him, we'll meet up at the O'Neil apartment. Then we'll find Splinter and Leatherhead, And then we get out of the city and find a way back to the island." He stated.
"How do even we get to the island if it's across the ocean?" Mikey asked.
"We'll cross that bridge later." Olly said as he looked over and noticed the coast is clear. "Alright. Time to move. See you guys soon." He said as he flipped over the Taxi and climbed onto the rooftop until he was out of sight.
"Be careful, Olly." Naomi said in concern.
"Okay, guys. You heard, Olly. Let's move." Tal said as they all rushed off to the O'Neil's place.
On the rooftops, Raph's group saw another portal opened up as a Stealth Ship flew out of it. "Dudes, this is worse than that giant Technodrome thing last year!" Casey exclaimed as they hid behind a wall.
"More like ten times worse!" Keno corrected. "Instead of an invasion of a single mother ship, they send groups of walkers, ships, and troops to take over the city! This is crazy!" He exclaimed before Raph's T-Phone rang as he quickly picked it up.
"Mikey! The Kraang just started the Invasion!" Raph explained to his little brother, "We're on our way to the lair and-"
"No go, bro! The Baddies tricked April and Robyn into bringing Irma to the Lair," Mikey cut him off, "Turns out she was a Kraang spy called Kraang Subprime and now the Kraang and the Foot know where the Lair is!"
"Say what?!" Raph exclaimed in shock while the others looked shocked as well. "They found the lair!?"
"Yeah! We managed to give 'em the slip, but Master Splinter stayed behind to hold them off and we got separated from Leo in the sewers. Olly went off to find Leo." Mikey explained.
"Well, where can we meet up, bro?" Raph asked desperately.
"We're on our way to the O'Neil apartment. Meet us there, dude!" Mikey quickly answered.
"Roger that!" Raph nodded as he ended the call.
"First, we lost Miwa, the Kraang invaded, and now the Foot know where we live!" Jenny listed while clutching her head. "This is a nightmare!" she exclaimed in anxiety.
"Well, it's about to get worse! Look out!" Keno cried out as a Stealth Ship flew by and fired at them, which they dodged as they fell from the roof with screams.
In the sewers, more droids were looking through the sewers and a bunch of destroyed droids on the floor.
"Kraang. Still no sign of the turtles." The droid said as Leo hid above them.
"Hurry Kraang, we must retrieve the turtles for the one called Shredder." The other responded as they left as Leo jumped down once the coast was clear.
"Shredder?" Leo asked himself as he ran off.
At the O'Neil's apartment, the sisters and the turtles regrouped and Kirby was nervously pacing around nervously when he saw the Kraang invasion.
"The city's overrun! What are we.. what is anyone going to do?!" Kirby asked in intense worry.
"We'll think of something, Dad." Robyn said to her father. "We just need a plan."
"But for now, we wait for the others." Naomi said to them. "They'll be here, and when we do, we find a way out of the city and back to our island."
"I hope so." Kirby said nervously as Tal was patching up Donnie's arm.
"No, I'm okay." Donnie said with a cringed as Tal kept wrapping the bandage.
"Don't be such a baby, Donatello." Tal said with a small smile. "It's not deep, but it did scorch your arm."
Donnie looked at Tal for a moment before taking a breath and twiddling his fingers, "Tal, seeing how it's the end of the world, again, I just wanted to let you know, how I feel," He said to her nervously.
Tal looked up at him, "How do you feel?" She asked, looking hopeful.
"I, I honestly don't know." Donnie admitted while looking away, "I know you're very special to me Tal, I just don't know how much," He said.
Tal rested a hand on his arm and he turned to see her smiling at him, "Take all the time you need," She said as Donnie smiled back. April saw this and just chose to smile too.
The roof then shook and they all looked up in concern as Kirby fell to his knees, "We're doomed! Doomed! Oh my poor sweet girls!" he cried out in despair.
"Don't worry Mr O Neil! This whole alien invasion thing is really no big deal, look." Mikey said as he opened the curtains, only to reveal dozens of people screaming while the Kraang rampaged across the city. "Oh... never mind." He said closing the curtains, Kirby passed out from all the stress much to their shock.
"Nice save, Mikey." Vee said with a brow.
"Oh boy." Mikey said in fear as he looked outside and saw the entire city being destroyed.
Outside, the people were running in a panic as the Kraang and their machines attacked from every angle. In the middle of the street, a little girl stood there crying when a Walker appeared and stepped on a taxi before seeing the girl and stomped towards her, but then a pizza delivery guy drove his motor scooter to its legs and quickly grabbed the girl as the scooter exploded upon impact with the Walker and it fell down.
The boy held the girl as he kept running, but then he stopped when he saw Shredder and his Foot Warriors glaring down at them. The boy screamed and ran away as the Foot Clan watched the invasion. "The city is ours, Master Shredder," Tigerclaw said to their master.
"Our forces are guarding every exit and entrance point in every part of the city," Kitsune reported, "No one gets in, no one gets out,"
"Since I was a boy, I have seen this very vision; the world.. in chaos!" Shredder said as he looked at the carnage around them.
Rahzar atop a water tower and howled at the moon before he leaped down infront them, "Master Shredder, the Kraang have sent word," Rahzar reported, "The turtles have been driven out of their lair, Subprime is battling Splinter, and Leonardo is not far from here. They're leading him straight to us." He explained while his eyes narrowed.
"Excellent, then it is the beginning, of the end." Shredder said menacingly as the fire spread further.
Back in the lair, the place was totally wrecked and Splinter was still fighting off Subprime.
"Now I've got you cornered, you monstrous rat!" Subprime said with rage.
"Corner a rat, and see what happens!" Splinter countered. Subprime growled with rage and tried attacking him. He blocked the attacks with his fists and flipped right over him, he pushed him back roughly and dodged an attack from the saw, Splinter then took out a knife to cut the arm off completely, and kicked him out of Donnie's lab. Suborime's armor was falling apart as he fell right out of it.
"Kraang shall dominate the Earth! You and your kin will be destroyed, Kraang will be back-!" He shouted right before he was crushed by some rubble.
Splinter looked around the lair with huge regret as it was completely destroyed; Splinter walked over and picked up a broken photo of himself, his sons, and his daughters and looked at it sadly. "Don't stand here like a fool, Yoshi. Find your family." Splinter told himself as he left to find them.
Olly was running from rooftops while avoiding contact with any Kraang or Foot troops as he then jumped down and hid in an alley as he took a breather before he hid further when a Kraang patrol rushed past him as he looked to see the coast was clear.
"This is getting worse and worse," Olly said to himself as he looked at the chaos the city was in. "The Kraang and Foot working together, The team is scattered and Leo's out there on his own fighting for his life. How am I supposed to find him in this mess?" He questioned himself.
He then looked at his T-Phone and tried to call Leo again, but got no answer. "And still no answer. Did he turn his T-Phone completely off to avoid capture?" He wondered as he sighed. "Think, Olivier, think. There must be some way I can find him."
Then in the distance, he saw the Foot Warriors and Shredder running across the rooftops, "Shredder? He's in a hurry." Olly said before he had a thought. "Wait, if he's out in the open with many Footbots with him and his mutant warriors, then that might mean that…" His eyes then widened when he gave a dreadful look.
"Oh no. Leo!" He said as he then climbed the rooftops again and followed after the Foot but was blocked off by Kraang droids and Biodroids. "You never make it easy," He said while drawing his axe.
With Leo, he exited the sewers once he saw the close clear as he got out of the manhole cover and quickly drew his sword as he rushed up to the corner and peak out when he saw many Footbots around the block before one came up behind him before he quickly sliced it and kicked it down.
But then, he blew his cover as the Footbots on the roof started firing arrows at him, which he deflected as he dodged each one before jumping into an alley to get out of sight. He then turned to the sidewalk before rushing down and kept his guard up before more Footbots jumped down as he deflected shurikens before he sliced their heads off.
Leo then turned to a construction area as he entered and kept his guard up as he took a breather and took out his T-Phone, which was on silent as he picked it up and looked to see he missed 48 calls from the others before more Footbots atta as he took them on with quick speed and skills with his swords as he sliced each one before more came as he kept fighting.
As the Blue-clad turtle fought, Shredder watched from atop a rooftop with Tigerclaw, Koya, Rahzar, Fishface and Kitsune beside him. "For a warrior so young, he fights without fear," Kitsune commented, sounding almost impressed.
"Indeed. He fights as bravely as Olivier's father." Tigerclaw said in agreement, seeing much of Orimura in Leo.
"He is young. Overconfident. Foolish." Shredder countered with a look as Leo blocked some shurikens and threw his sword at a Footbot as he sliced more and retrieved his sword before continuing fighting.
"Do not take chances with him, Master. We should destroy him quickly!" Rahzar insisted, seeing Leo fighting against their many Footbots proves that he's as skilled as he was before.
"Archers." Shredder ordered, ignoring Rahzar as the Footbots ready their bow and aimed at Leo as he kept fighting. "Fire!" He yelled as the archers fired their arrows at Leo.
Leo turned when he saw the arrows fly towards him. "Oh, no." He said in dread.
"Just a little further to the O'Neil's place!" Casey called as he and his group ran past the dragon gate but then a giant portal opened up in front of them as a robotic tentacle came out while they and the rest of the people of New York looked in horror as coming out of the portal was Kraang Prime, who had a giant vat of mutagen on his head and cannon on his left arm.
"Yes! Kraang Prime returns to Earth!" Kraang Prime exclaimed with a sinister smile while the people of New York screamed and ran off in panic.
"That's one BIG Kraang!" Keno gasped in shock.
"Uh, Raph, you got some kind of plan to fight him?" Jenny asked nervously as the group backed away.
"Uh, not really, no." Raph said in slight fear as they hid away from Kraang Prime.
"People of Earth, the Kraang-forming of your world is about to begin!" Kraang Prime announced as he aimed his arm blaster and shot tons of mutagen out that covered the people.
"No!" Both Raph and Jenny yell in horror as the people got out of the mutagen puddles, but they were turned into Kraang-like hybrids as they started walking, screeching, and moaning like zombies while Raph's group looked on in horror.
"Now, that is really messed up!" Casey said in horror as the heroes looked in dread, seeing that the Invasion had just gotten even worse now that Kraang Prime had arrived.
