Joining Forces with The Other Turtles

Summary:

One-shot story. After taking down the Dimensionizer in the 1987 universe, 2012 Donatello and his '87 counterpart head to the Primary Turtle Reality to deactivate the last Dimensionizer. However, Kraang Subprime, the Kraang's master spy and Kraang Prime's right-hand man, had teamed up with his cousin, '87 Krang, to destroy the turtles and hijacks '87 Donatello's portal to prevent them from foiling their schemes, leading to the two Donatellos to end up in the 2003 Turtle universe, where both Donnies enlist the help of that universe's Ninja Turtles to destroy the Dimensionizers and stop both Krangs from destroying the multiverse. (A slight rewrite of "Trans-Dimensional Turtles")

Notes:

A couple of weeks ago, I watched the 2012/1987 TMNT crossover "Trans-Dimensional Turtles" and I was pretty impressed with the episode, though one of the biggest complaints of the 2012 show is that the 2003 Turtles never got to meet their 2012 counterpart nor did they show up in crossover episodes. I understand the reason behind it, since the 2003 voice actors were based in New York while the 2012 and 1987 voice actors were LA Union actors, but at the same time, I can't help but think what a wasted potential it was. Like, I grew up with the 2003 incarnation, since they were my introduction to the TMNT universe, but the face they are barely recognized nowadays frustrates me to no end

This rewrite follows the same events as the original episode until the moment the 1987 and 2012 turtles deactivate the Dimensionizer in the 1987 universe. Here, Kraang Subprime will use his portal hacking device he used in the episode to jack the portal and send '87 and '12 Donatellos to the 2003 universe in the hopes of preventing them from reaching the Prime/Mirage universe.

To distinguish the Turtles variants, I will be using codenames for each of them; the 2012 versions will be referred as "Leonardo", "Donatello", "Raphael" and "Michelangelo", the 2003/4Kids versions will be referred as "Leo", "Don", "Raph" and "Mikey" (their nicknames in the '03 show) and the 1987/Fred Wolf versions will be referred as "L.", "D.", "R." and "M." (a reference to the initials on their belt buckles in the '87 show).

Work Text:

1987 Reality

Having escaped from the captivity of Kraang Subprime and Krang inside the Technodrome, the Ninja Turtles and their two-dimensional counterparts have landed back to the two-dimensional reality, which served as the home dimension of the other four turtles, thanks to Donatello's counterpart projecting a portal through his portal ray gun. During these events, the two-dimensional turtles had brought on their counterparts to help them stop Krang from destroying their realities by deactivating the Dimensionizers placed on the Channel 6 News building and the eight turtles had deactivated one such device inside their counterparts' home reality. They now needed to deactivate the other one inside the two-dimensional reality.

"Finally, back in the real world," M. exclaimed, content of having returned to his home reality.

"Now let's just keep it from blowing up," R. remarked.

"On it," Donatello told the others as he ans D. climbed onto the satellite tower to remove the Dimensionizer.

Suddenly, just as the two Donatellos were reaching the Dimensionizer placed onto the tower, Kraang Subprime and Krang emerged from the portal, having caught up with the turtles.

"Everywhere you go, we follow, freaks!" Kraang Subprime taunted the turtles.

"We did it!" Donatello informed the turtles as he and D. removed the Dimensionizer and deactivated it. "Two Dimensionizers down!"

"No matter. There is still one left in the Primary Turtle Reality," Krang articulated. "If those turtles are destroyed, then so are all of you."

"Donnies, get tp the third reality!" L. ordered the Donatellos.

D. adjusted the portal ray projector so he can transport himself and his counterpart to the Primary reality. "There!"

Once D. summoned a portal through the projector, the two Donatellos leaped from the satellite tower and jumped onto the portal. However, Kraang Subprime used his portal hacking device, which he previously utilized to send the eight turtles to the Technodrome, to hijack the portal D. created and prevent both Donatellos from reaching the Primary reality.

"But neither of you will be able to deactivate it in time," Kraang Subprime blurted up upon using the device before letting out a malicious laugh and facing off against the turtles with Krang.


2k3 Reality

Donatello and D. emerged through the portal and landed on top of one of this reality's buildings. Much like D.'s reality, this dimension both Donatellos were in was also two-dimensional, albeit a bit more modern than D.'s dimension. Notably, both Donatellos' appearances were altered to match with this universe.

"Where are we?" Donatello stumbled as he got back on his feet and looked around his surroundings, before examining his appearance. "Wait a minute, this isn't the Primary Turtle reality."

"Look," D. said to his counterpart as he pointed his finger at a rooftop, where four different turtles were standing on a building ornament.

Turtles Count It Off!

One! Two! Three! Four! (Turtles!)

The four turtles then jumped out of the ornament and leaped onto the building next to the two Donatellos, each brandishing their weapons; a turtle with a purple eye band moved his bo staff before positioning himself in a fighting stance, while the turtle with the light blue eye band placed his swords around his face, the red turtle twirled his sais and the orange-colored turtle whipped his dual nunchakus. Though the turtles were similar, each of them were distinguished by their different skin colors; the blue turtle had a forest green skin tone, the purple turtle olive green, the red turtle dark emerald green and the orange light turquoise green.

"That was awesome!" D. was amazed in watching the Turtles preparing their weapons.

"Yeah, yeah, I've seen much better poses," Donatello muttered in a sarcastic tone.

Don noticed Donatello standing next to him. "You're... me? There's no way I'm seeing this."

"Nah, that looks like some bozo pretending as you, Donnie," Raph told Don in his usual snarky, hot-headed tone and Brooklyn accent. "And look, he's got a gap in his teeth. There's no way he'd looker any dorkier, am I right?" Raph's comments brought the ire of Donatello and his brothers, Leo and Don, who glanced at him in anger. "What?"

Mikey saw D. standing in front of Donatello and burst with joy and excitement, having not seen Don's counterpart since the Shredder's multiversal ordeal a while ago. "Dude! Come here!" Mikey ran towards D. and hugged him tightly. "Aw, man! I have missed so much!"

"Easy there, my friend," D. struggled to speak as he felt himself getting tightened by Mikey's hug.

"Oh, great," Raph grumbled upon seeing Mikey hugging D., getting flashbacks of D. and his brothers hanging out with Mikey in his head. "This again."

Mikey let his hold on D. go and giddied with excitement over seeing D. again. "I knew we were gonna see other again! So, how's your brothers? Is there any other timey whimey adventure we can have?"

"Well, that's precisely why we're here," D. told Mikey.

"So far, we've managed to deactivate the Dimensionizers Krang placed onto our realities and we tried to get to the Prime Turtles reality to defuse the Dimensionzier Krang placed," Donatello explained. "But for whatever reason, we landed in this dimension."

"Hold on. Krang tried to destroy both of your realities?" Leo inquired.

"Yeah. How are you guys familiar with Krang?" Donatello asked Leo.

"Not too long ago, Krang had entered our dimension and planted the device you mentioned on the Channel 6 building. We tried to stop him, but he was too powerful," Don recalled their encounter with Krang to Donatello.

"Not to mention, he had a silly baby suit for a body," Raph commented on Krang's mechanical body. "What's up with that?"

"Wait, Channel 6 exists in this dimension too?" Donatello retorted.

D. then pulled out his portal ray gun and used it to track down the Dimensionizer in this reality. "As long as my device can detect the portal tech Krang placed, it'll be easier to track down the location of the Dimensionizer."

"Woah," Mikey glanced at the portal ray projector D. was holding. "Let me have it." Mikey then grabbed the portal projector and posed with it. "Behold, evildoers, Turtle Titan has returned once again to strike fear into the criminal underworld with the most deadliest weapon he ever used, the laser blaster!"

Donatello sighed and facepalmed as he watched Mikey posing with D.'s portal projector and letting out laser sounds. "And here I am thinking my Mikey was a weirdo..."

D. then grabbed the portal projector from Mikey. "Careful, this isn't a laser blaster. I created this projector so I can summon portals from other dimensions and track down Krang's Dimensionizers." D. then adjusted the projector to detect the Dimensionizer's location.

"Are you sure this thing can track down the Channel 6 building?" Don asked D.

"Of course," D. replied before noticing the projector detecting the location of the Dimensionizer. "There." D. then pointed out the location. "The Channel 6 building must right there."

"Let's go, guys," Leo then told the turtles.

"Better hope nothing bad happens," Donatello blurted out as he followed the turtles and D. to the Channel 6 building.

Just as the turtles were leaping to several rooftops to reach this reality's Channel 6, they were being watched by the Foot Clan ninjas, who observed the turtles reaching the news building and followed them. Moments later, the turtles and Don's two other counterparts were able to reach the Channel 6 building, where, much like in the other two realities, the Dimensionizer was placed onto the satellite tower.

"There's the Dimensionizer," Donatello told the turtles as he pointed the building's satellite tower. "Once we deactivate it, we need to head to the Primary Turtle reality and deactivate the other Dimensionizer."

"Uh, guys?" Mikey frenetically told the others as he saw the Foot Clan ninjas following them and surrounding the turtles and the two Donatellos. "Looks like we've got company."

"Then we're gonna need to hold off the Foot ninjas," Leo commanded as he and his brothers pulled out their weapons. "Donnie?"

"Yeah?" All three Donatellos spoke at once.

Leo let out a sigh, being confused over which Donatello he referring to. "Remove the Dimensionizer and deactivate it."

"Right on cue," Don nodded ad he and his two counterparts climbed onto the two.

While the three Donatellos were busy removing the Dimensionizer, Don's brothers were fightimg against the Foot ninjas; Leo saw two Foot ninjas charging at him with their swords and jumped over them, kicking one of them on the back before engaging with the other in a sword fight, gripping his sword onto his to prevent the ninja from striking him before launching a sweep kick that struck him in the ankles, while Raph was dodging the ninjas' attacks before launching a sweep kick that knocked out several ninjas and Mikey jumped around the ninjas and used his nunchakus to stun the ninjas.

"Nice moves, but can you handle this?" Mikey taunted the ninjas as he swung his feet around and knocked the ninjas out. "Talk to the feet!" Mikey then turned around to check if Don and his counterparts were able to remove the Dimensionizer. "Is this gonna take a while or what?"

"Got it!" Donatello informed the turtles as he removed the Dimensionizer from the satellite tower and threw it onto Don.

"Now, this has to be either the most fascinating thing or the weirdest thing that I have ever seen," Don articulated upon seeing the Dimensionizer in his hand.

"Now, we need to get to the Primary Turtle Reality," Donatello remarked before turning to D., who was preparing the portal ray gun to send him and his two other counterparts to the Primary Reality.

"Alright," D. nodded as he shot his portal projector near the building and called out the turtles as they were fighting off the Foot clan. "Guys. This should take you guys to my dimension. You'll have to take care of Krang while we deactivate the last Dimensionizer. Hurry!"

Leo was dealing with one of the Foot ninjas as he threw a barrage of kicks that knocked him out before seeing the portal near him. "Come on, guys! Let's get to the portal!"

Leo ran into the portal, with Raph and Mikey following his lead, leaving the Foot ninja behind just as D. projected another inter-dimensional portal, in which him, Don and Donatello jumped onto before it closed on them, much to the confusion of the Foot ninjas.


Prime Reality

  The

After escaping from the Foot's pursuit and destroying the Dimensionizer in Don's reality, the three Donatellos emerged from the portal and landed themselves onto a building in a different dimension. Only this time, the reality the three of them were in was presented as a black and white comic booky compared to their own realities. Unlike in any of their realties, the three Donatellos each maintained their appearances from their perspective realties.

"Oh, man. I can't believe I almost broke my shell," Donatello murmured as he saw the dimension. "So, this is the..."

"Yeah. The Primary Turtle reality. The one that came before any of our realities," Don informed Donatello before reaching out D. and helping him back on his feet. "You okay?"

"Yup," D. assured Don before glancing at the reality. "Woah. I can't believe we're back here."

"Hold on. You two have been here before?" Donatello asked both of his counterparts, curious about their familiarity with the Prime Turtles reality.

"It's a long story," Don told Donatello, reminiscing about the first time he and D. were stranded in this reality. "Last time we ended up here, we joined forces with the Prime Turtles to stop their world from being destroyed by the Shredder."

Hearing the Shredder's name caused Donatello to raise an eyebrow at Don, baffled at the fact that Shredder could have planned to destroy an alternate dimension.

"My Shredder, I mean," Don corrected Donatello, hoping it would ease his counterpart's confusion over which Shredder he referred.

"And they helped us take down that grade-A meanie and the Technodrome," D. then continued from Don, recalling the Prime Turtles teaming up with his brothers and Don's brothers to defeat the Shredder from Don's reality before he could have destroyed the multiverse. "Though it wasn't easy at first."

"The Prime Turtles mistook us for enemies when when we first saw them. It wasn't until we convinced them of the situation they decided to join us," Don continued.

"Okay..." Donatello pondered. "So, Krang said he placed the last Dimensionizer somewhere around here. Maybe the Prime Turtles could help us take it out."

"I hope so," Don remarked.

"Look," D. told his counterparts as he indicated them of Channel 6's location in this reality. "Channel 6 must be this way."

"Then there's no time to waste," Don commanded. "Let's move!"

"On it," Donatello nodded as he ran alongside his counterparts.

  The

The Three Donatellos then jumped from rooftop to rooftop and began heading towards this reality's Channel 6 building, unaware they were being watched by this reality's Turtles. As they nearly reached their way to the Channel 6 building, the three Donatellos were stopped when they saw a couple of shurikens hit a nearby pole, much to their dread. The three turtles then turned around and saw this universe's Turtles, also color in black and white much like the place.

"It's the Prime Turtles," Donatello seethed in shock.

"Uh, hi, guys," D. greeted the Prime Turtles. "Long time no see. We're looking for the Channel 6..." D. suddenly sensed dread within his body as he saw Raphel-Prime preparing his sai and gritting his teeth.

"Eh, check out the teeth gap at this wanna-be," Donatello-Prime told his brothers as he glanced at Donatello.

"What a loser," Michelangelo-Prime mocked Donatello's gap and laughed.

"Hey!" Donatello was offended by the Prime Turtles mocking the gap in his teeth. "Can I at least have one minute..." Donatello then quickly screamed in rage "...WITHOUT A TURTLE MAKING FUN MY TEETH GAP?!"

"Woah, woah, easy there, Donnie," Don calmed down his counterpart before speaking with the Prime Turtles. "Listen, guys. We just need you to help us reach the Channel 6 building and take out the Dimensionizer Krang placed. If we don't get there in time, all of our worlds will be destroyed."

"What's a Krang?" Raphael-Prime flinched upon hearing Don mentioning Krang. "Sounds like French to me."

"So this Krang guy must have sent you three to tresspass our universe and destroy it without us noticing," Leonardo-Prime remarked as he prepared his weapons to attack him.

"What?" Don yelped as he attempted to talk with Leonardo-Prime. "You've got this all wrong. We're only trying to help you. We've been there before. Don't you guys remember?"

"Yeah, I don't think they do," Donatello non-chalantly told Don.

"I have a bad feeling about this," A frighted D. told Don and Donatello as he saw the Prime Turtles gritting their teeths and preparing to attack the three of them.

"That's right," Raphael-Prime taunted in a threating tone. "You better kiss your butt goodbye."

Donatello realized it was pointless to reason with the more aggressive Turtles as they needed to get to this reality's Channel 6 building. "Guess the prep talk is over. Move, Donnies!"

As the Prime Turtles were chasing the three Donatellos, Leonardo narrated, his words appearing in front of a comic book font; "We chased down those freaks down the rooftoops, just as they were running for their lives." Donatello-Prime tried to strike his three counterparts as they walk down the stairway. "Donatello charges for the attack, but the three wannabes manage to avoid from getting hit by it." Leonardo-Prime then leaped into the sky with his swords out, ready to attack them. "I come in for the strike..." The three Donnies dodged Leonardo-Prime's strike. "...But they're really goodToo fast I'd even say, but I bet they won't be good enough to catch up with our speed."

"What's up with the narration? Why is he talking in first-person?" Donatello questioned Leonardo-Prime's narration as he continued running from the Prime Turtles.

"That's the same question I asked myself the first time I heard it," Don replied while making his way towards the Channel 6 building.

"Not to interrupt, but we need to hurry if we're going to destroy the Dimensionizer," D. informed both of his counterparts.


1987 Reality

At the same time, Leo, Raph and Mikey found themselves teleported to the other two-dimensional reality, which was 80s-based compared to their own. The three of them had previously been there when they helped out their counterparts dealing with the Shredder and once again, they would end up aiding them.

"There," Leo told Raph and Mikey as he saw their two other variants battling Kraang Subprime and Krang on the streets. "Donnie's counterpart told us we should help our other selves take out Krang. Alright, guys, Don here's what we need to do." Leo turned to Raph. "Raph, you help our other selves take care of that other purple alien in the tech suit."

"You can count on it, bro," Raph exclaimed as he prepared his sais.

"Mikey, you and I will have to take down..."

"Cowabunga!" Mikey screamed in excitement as he rode on his stakeboard and joined the battle, cutting off Leo's monologue.

Leo let out a sigh upon seeing Mikey jumping into action without listening to his plan.

"He never listens, doesn't he?" Raph grumbled.

Leo and Raph saw their other two counterparts, who had been busy fighting off Krang and Kraang Subprime with Mikey's two counterparts while the Donatellos were locating the Dimensionizers. Just as Kraang Subprime was about to attack Raphael, Leonardo and L., Raph and Leo jumped in and struck Kraang from behind, giving Raphael and the two Leonardos enough time to dodge his attacks and meet up with the two.

"Good thing you guys showed up for the help," L. told both Leo and Raph.

"Wouldn't have left any of my brothers in danger," Leo remarked. "So, what's the plan?"

Leonardo took a glance at his other self and was curious to know how familiar he was with L.. "Wait, you two know each other? And is Krang after you and your brothers too?"

"We've aided each other in the past, having taken down the Shredder before he had the chance to destroy the Multiverse," Leo explained, making Leonardo's anger over hearing Shredder's name boil, while Leo continued. "But lately, Krang had targeted our universe and two of Donatello's counterparts had helped us take down the Dimensionizer."

"And one of them had brought us here to help you guys take down that freak," Raph said in a gruff demeanor.

"As if I didn't have any more reasons to hate him even more..." Leonardo flinched, feeling his rage towards the Shredder building up inside and he had plenty of reasons to feel it; Oroku Saki had killed Tang Shen and abducted her daughter, Miwa, and trained her to become a deadly assassin for the Foot, and had killed his mentor, Splinter, in front of Leonardo's eyes before he left Earth alongside his brothers, April and Casey as it was destroyed by the Heart of Darkness. The thought of the Shredder, or any version of the Shredder, destroying the multiverse to take out the turtles increased his resentment towards him further.

"Easy there. I understand your anger towards the Shredder, I felt it too, but whoever your Shredder is wasn't the one responsible," Leo assured before turning to L. "Now, how do we take down those two punks?"

"You two will have to help us take down the other Krang, while Raphael and Michaelangelo deal with Krang," L. ordered. "We need to make sure they're both subdued while the Donatellos reach the last Dimensionizer."

"Woah, woah, woah, hold it, buddy," Raph cut L. off. "Last time we met up with you and your bros, y'all acted like a bunch of clowns, and now you're expecting us to follow your orders?" Raph scoffed. "There's no way am I gonna be led by some wacko like you." Raph then turned to Leonardo's counterpart. "Nor am I gonna team up with Leo's other wannabe."

"What?!" Leo was offended by Raph's comments.

"Ha!" Raphael laughed, much to Leo's annoyance. "Now, this is a version of me I like."

"Take it easy, Raph," Leo calmed Raph and mended the situation. "This isn't the time for mock our other selves."

Raph calmed down and apologized. "Sorry, Leo, guess I went a bit overboard." He then turned to L. again. "But just so you know, you're not the one leading the team..."

Suddenly, Kraang Subprime shot his laser beam at the three Leonardos and Raphaels, though the six turtles were able to avoid the attack before they were struck by the laser.

"You were saying?" L. sarcastically remarked as he raised an eyebrow at him.

Raph tilted his head and let out a sigh of frustration just as Kraang Subprime approached the six turtles.

"Well, well, well," Kraang Subrpime remarked as he saw Leo and Raph standing next to their counterparts. "Looks like you've brought yourself another version of the turtles, and I thought Krang had taken care of you, but alas, I will deal with you myself."

"Oh, yeah?" Raph taunted Kraang Subprime. "Bring it on!"

"Dude, I was about to say that," Raphael told Raph.

The three Leonardos and Raphaels charged at Krang Subprime, evading his laser beams, before Leo jumped to strike the creature, who used his suit to punch down Leo, while Raphael and Raph attempted to strike Kraang down, but were sent staggering to the ground.

"He's too powerful," Leonardo commented. "We need to find a way to distract him."

Kraang Subprime laughed manically. "You're finished, turtles. I will enjoy beating you to..."

"Booyakasha!" Michelangelo cried out as he jumped onto the top of Kraang Subprime's machine, whose head resembled a human female with glasses.

"Now that's what I call a distraction," R. looked at the screen and told the audience, much to Raph's dismay, who facepalmed in annoyance over his fourth-wall break.

"Come on, guys, let's take down this freak!" L. told his counterparts, who all ran at Kraang Subprime while R. ran towards Krang, who was being delt with by Mikey and M.

"Hey, Krang, I'm right here," Mikey taunted Krang as he circled his skateboard around Krang, confusing him. "No, over here." Krang tried to land punch onto Mikey, but the turtle was able to avoid to get himself hit by the pink creature through his skateboard. "Over here." Mikey continued to taunt Krang with skateboard, leaving the creature confused, giving M. the perfect opportunity to jump at him and grab him by the upper part of his mechanical suit.

However, Krang was able to notice M. riding onto him and grab the turtle from behind, throwing him onto the ground.

"Gotcha," R. said as he jumped onto Krang's mechanical body and grabbed the head, distracting the alien and leaving him unable to notice where R. was.

"Oh, curse you, you half-witted turtle!" Krang screamed.

"Man, I love the 80s," Mikey said as he posed with his skateboard.


Prime Reality

At the same time, the three Donatellos were finally able to reach this reality's Channel 6 building, where the last Dimensionizer was located, and managed to avoid pursuit from the Prime Turtles.

"There it is," D. told both of his counterparts as he pointed the Channel 6 building.

"Okay then," Donatello nodded. "All we have to do is to take out the Dimensionizer from the satellite tower and deactivate it."

"But it looks like we're only who reached Channel 6," Don murmured as he saw the Prime Turtles catching up with them and leaping onto the Channel 6 building.

The Prime Turtles positioned themselves in to their fighting stances and tightened their weapons while Don and D. pulled out their perspective bo staffs.

"Donnie, take out the device," Don told Donatello. "We'll take care of them."

"Right," Donatello nodded as he jumped onto the building's satellite tower, where the Dimensionizer was placed.

"Come on!" Don said as the Prime Turtles jumped onto both him and D. while Donatello was climbing onto the tower.

Leonardo-Prime charged at Don with his sword, but Don was able to block it with his staff and tried to push the katana was from him, while D. dodged Michelangelo-Prime's nun-chakus. Don then ducked and struck Leonardo-Prime on the ankle with his staff, swiping him onto the ground, while D. jumped Michelangelo-Prime's behind and saw Raphael-Prime charging at him before ducking down and causing both monochrome turtles to accidentally hit onto each other.

"Got it!" Donatello informed both of his counterparts as he removed from the control tower and leaped back onto the ground, with the two other Donnies gathering around him as the Prime Turtles prepared to attack them.

"Sorry, guys," Don told the Prime Turtles. "But this family reunion will have to wait." Don then turned to his counterpart, who pulled out his portal ray gun. "Now!"

"On it," D. nodded as he shot the ray gun and summoned an inter-dimensional portal, which the three Donatellos were able leap onto and leave this reality, leaving the Prime Turtles confused and baffled over their sudden disappearance.


1987 Reality

The three Donatellos jumped out of the portal and reached back to the 80s reality, with the Dimensionizer from the Prime Reality being held by Donatello.

"Come on, guys," Donatello told the turtles and their counterparts, who were dealing with Krang and Kraang Subprime. "We're good to go."

"Aw yeah," Michelangelo smiled as he heard Donatello telling him and the other to return to his dimension before jumping out of Kraang Subprime's mechanical suit. "We outtie!"

Realizing that time was running out, Leo and Raphael managed to subdue Krang by kicking him in the upper part of his mechanical suit, while L. launched an uppercut that struck Kraang Subprime on the check. All nine turtles then jumped onto the rooftop and followed the three Donatellos to the portal.

Kraang Subprime laughed as he saw the turtles escape from the two-dimensional reality and grabbed his portal-hijacking device. "You can't escape so easily, freaks!" Kraang then pressed the device and was able to make the twelve turtles end up on the Technodrome once again.


Technodrome

The eight turtles found themselves back into the Technodrome, having been brought there by Kraang Subprime, only this time, they were joined by the other four turtles.

"Oh, no," Michelangelo complained. "We're back here?"

"Hey guys, check this out," Mikey called his brothers as he admired his third-dimensional features. "I'm more detailed now!" Mikey then flexed his muscles, now also third-dimensional, much to Raph's dismay. "Aw, yeah, look at those babies." Mikey then kissed both of his biceps.

Raph slapped him on the back of his head. "Knock it off, Mikey!"

"Ow!" Mikey yelled.

"This isn't over, guys," L. told the turtles.

"Welcome back, heinous freaks," Krang told the turtles as he and Kraang Subprime emerged from the portal.

"You're not going anywhere as long as I have this baby," Kraang Subprime said as he oulled out his portal hijacker. "I can hack your portal all day long..." Kraang's monolgue was cut short when Leonardo threw his shuriken at the device and destroyed it, much to his irritation. "Ah, Kraang."

"It's over, Krang. We've deactivated all of your Dimensionizers and foiled your plans," Leo told Krang. "You're finished."

"That's right, pink dude," M. said. "You can't blow up our realities anymore."

"Blow up?! Realites?!" Kraang Subprime said in a shocking tone before turning to his cousin, who let out a sheepish grin. "You have been trying to wipe out dimensions we've been trying to mutate for thousands of years?! ARE YOU INSANE?!"

"Well, you did say wipe out the turtles at any cost," Krang attempted to justify his actions.

"This is why I banished you to Two-Dimensional Earth in the first place," Kraang Subprime scolded his cousin as he repeatedly punched Krang's mechanical body. "Because you're an idiot! A moron! A dingleberry! So, you know what? I'm kicking you back!"

"Oh, no," Krang murmured as Kraang Subprime kicked him into the portal, sending him back to his home reality. "Not agaaaain!"

"I've had enough Turtles for a millennium!" Kraang Subprime declared as he attacked the Turtles, though all twelve turtles were able to leap away from it.

"Let's take this wad of chewing gum down," Leonardo told his fellow turtles.

"With pleasure," Raphael nodded.

"Let's do it!" Raph exclaimed as he and the other turtles prepared their weapons and charged at Kraang Subprime.

"I got your back, bro," R. told Leonardo.

All twelve turtles jumped at Kraang Subprime at once and managed to avoid his laser blasts, with each of them striking him with their respective weapons. Just as Kraang Subprime was shooting lasers from the human head placed onto the machine, R. pulled out a pizza again and thew it at the head, though it didn't affect Kraang much as he melted the pizza with the laser and tried to attack R. and Raphael, but both red turtles were able to avoid from getting hit while Raph jumped from behind and used his sais to pulled the replica human head out of the mechanical device, destroying it.

"Nice move, Raphael," Raphael complimented Raph's move.

Despite having lost the mechanical head, Kraang Subprime still managed to fire his laser blasts from his arm and tried to attack all three Raphaels, though the were able to avoid from getting blasted by the lasers.

"I've had enough of this dweeb," L. told his other counterparts as they charged to strike Kraang Subprime.

"Then let's take him down once and for all," Leo declared.

"Turtle Power!" Leonardo screamed L.'s battle cry.

L. jumped in to strike Kraang Subprime with his swords, though they were ineffective against the machinery and Kraang easily destroyed the katana with one punch.

"That's not good," L. said as he saw his katanas destroyed.

"Here!" Leo told his counterpart as he threw one of his katanas to him, allowing L. to hold off Kraang Subprime's plasma-blade while Leo leaped from Kraang's behind and cut off the legs of his mechanical body and Leonardo rolled onto Kraang's side.

"What the..." Kraang Subprime muttered as Leo cut off his suit's legs, causing it to fall on the ground, while Leonardo grabbed him from the machine's lower part. "What are you doing?" Leonardo then threw him off the mechanical body. "Noooooo!"

Michelangelo quickly kicked Kraang Subprime with his feet, toying him around like a football. "Aw yeah!" He then turned around to M. and kicked Kraang towards him. "A little hackey Kraang, Michelangelo?"

"Hey, can I join you guys?" Mikey said in excitement as he joined his two counterparts.

"Sure thing, bro," M. told Mikey as he threw Kraang towards him.

"Put me down, you maniacs!" Kraang Subprime screamed as he was being kicked around by the three Michelangelos.

"Booyakasha!" Mikey screamed his counterpart's phrase before hitting Kraang Subprime with his head and Donatello whacked the alien with his bo staff.

"Heads up!" Don told D. as he grabbed the portal ray projector and shot near Kraang Subprime, opening a portal to the Primary Turtle Reality.

"No!" Kraang Subprime as D. leaped near him and used his bo staff to punch him in the head and send him to the Prime reality. "I hate black and white!" The portal then closed down on him, leaving Kraang Subprime stranded there.

"Well, that wasn't such a chore now, was it?" R. told the group.

"Yer tellin' me," Raph nodded as he placed his shoulder onto R.'s. "You know, I'm starting to like ya guys now."

"Same," Raphael agreed. "We should do this again."

"And as long as you two work on your anger issues, I think we can get along even better," R. told his counterparts, much to their irritation, and let out a small laugh.

"Leonardo," Leonardo talked to his counterpart as he placed his katana back onto his shell. "Thanks for everything."

"No, thank you," Leo told his other self as he placed his hand onto his shoulder. "Without your help, our realities would have been destroyed."

"And we all did together, as a team," L. then followed.

"No, as brothers," Leonardo told his counterparts as he reached is hand, with both of his counterparts placing their hands onto his, before all three Donatello, Raphael and Michelangelo variants joined in.

All twelve turtles lifted their hands up and cheered together "Turtle power!"

"It's party time!" M. shouted in excitement.


2k12 Reality

To celebrate their victory over Krang and Kraang Subprime, the Turtles invited both of their two-dimensional counterparts to their own lair, which compared to the lairs of either of their counterparts, was located inside the subway station and was modeled to resemble a home rather than a base. The two-dimensional turtles have visited this place briefly after removing the first Dimensionizer, but this was a first time visit for the other two-dimensional turtles, having had several lairs that were destroyed during their encounters with their adversaries.

Their first lair was destroyed when the Mouser robots attacked them and left it in ruins, which prompted their Master Splinter to seek refugee inside an underground base of Y'Lyntian origin, which had served as their lair for years until Karai took over the Foot Clan as the Shredder for a time and destroyed the base as an act of revenge against the Shredder's exile, forcing them to relocate themselves to an abandoned water pumping station in Central Park as their new base.

While they were adjusted living in the new lair, the turtles had longed for the cozy, warm feeling they had back when they lived in their original lair and seeing the lair of their other selves as well as sharing space with both of their variants almost gave them at feeling.

Inside Donatello's lab, the three of them were enjoying pizza as they were gushing about their scientific knowledge, while the two Raphaels were playing pinball, with Raphael watching them as his two counterparts were using the pinball machine. Much to his surprise, Raph's pinball wasn't able to catch up with the speed of R.'s pinball, which entered the finish line, and R. exclaimed in excitement.

"Oh, come on!" Raph shout out in frustration over losing to his counterpart in pinball.

"Who's the yahoo now?" R. told his counterpart in snarky tone.

"Lucky shot," Raph grumbled.

Overjoyed in seeing his counterparts interact with one another, Raphael quickly placed his arms around their necks and pulled them together. "I love you guys!"

Meanwhile, the three Leonardo were watching Space Heroes on the television, which was Leonardo's favorite show to watch and had quoted several lines from the show while leading the team, citing the protagonist of the show, Captain Ryan, as a role model. L. was also invested in the show as he watched it alongside Leonardo while Leo was unfamiliar with the show, having not heard it until now.

"So, this is how Captain Ryan appears in this show?" L. commented on Captain Ryan's appearance.

"Yep," Leonardo nodded.

"Wow. That's so insane," L. remarked. "In my world, Space Heroes is a live-action show, not a cartoon."

"Really?" Leonardo said before letting out a sigh. "Oh, man, how did I not know this until now? I should check it out if there is one."

"Uh, I don't mean to interrupt you guys talking about this Space Heroes show," Leo informed both of his counterparts. "But we don't have it in my world."

"What?!" Both Leonardos exclaimed in shock.

"Yeah. Instead, there's a cartoon based on the Justice Force," Leo told his counterparts. "Mikey watches that show often."

"The Justice Force?" Leonardo asked his counterpart. "Are they real superheroes in your world?"

"Yeah," Leo replied. "Much like me and my brothers, they also fight for justice and protect the city."

Leonardo couldn't contain his excitement upon hearing the existence of a superhero team in Leo's reality and immediately gushed. "That is so dope. I wanna join the Justice Force."

"Me too!" L. exclaimed.

"Cowabunga!" M. shouted out as he jumped behind the Leonardos with his skateboard, cutting off their conversation.

"Booyakasha!" Michelangelo followed M. as he leaped with his own stakeboard.

"Heads up, Leos!" Mikey exclaimed as he leaped onto the Leonardos with his skateboard, while the Leonardos ducked on the ground in order to not get hit.

"Careful, Mikey!" Leo warned his brother. "You could have hit any of us!"

"Sorry, Leo," Mikey told Leo. "But I was just hanging out with my new bros. Isn't that sweet?" Mikey then flipped his skateboard. "Woohoo!"

While the twelve turtles were busy hanging out together, a tall mutated rat with burgundy marital arts rope was observing from the sidelines as he watched the turtles enjoyed the moment and heard the sounds of laughter and joy that radiated the lair, flashing a small smile and giving him the conformation that, no matter which version of the turtles in this vast multiverse, the brothers had always sticked out to each other and remained together not as a team, but as a family.

Notes:

And that's the end of the story. This is the first time I've written a TMNT fanfic, so if I had mischaracterized some of the characters, I apologize. As for what happens after the story, the 2003 and 1987 turtles return to their perspective home realities while the 2012 turtles head back to Professor Honeycutt's spacespace, the Ulixes, leading for the story to continue in "Revenge of The Triceratons". I hope the explanation of the 2003 Turtles inclusion in "Tran-Dimensional Turtles" was handled pretty well and I wish I had done a better job in exploring it more, but since the original episode is 22 minutes, I condensed their appearance a bit to match with the episode's length.

The line "Kiss your butt goodbye" is a variation of the "Kiss your butt goodnight" from the second issue of the original TMNT comics and Mirage Leonardo's narration is meant to invoke the narration style of these comics. The Justice Force appeared in both the Mirage comics and the 2003 show and, given how much 2003 Mikey is a fan of comics and the Justice Force, he would definitely watch show based on them. Speaking of the Mirage Turtles, their appearance here actually predates "Turtles Forever" in terms of chronology, hence why they're not able to recognize '87 and '03 Donatello, whose stories follow the events of "Turtles Forever".

Let me know your thoughts on this story and I hope you liked it. Until then, stay safe and take care.
