-Teenage Mutant Ninja Turtles: Out of the Shadows dimension-

Donatello13 readied himself - his thick green fingers flexing around his long bo staff, his feet spreading out in a position ready for action - as a crush of Purple Dragons rushed towards him. In the rain-drenched darkness, all that was visible were the gang member's muscular outlines and the glint of their weapons.

Donatello13 took a breath.

The first Dragon came rushing towards him, flailing a crowbar tinted with red, but Donatello13 dodged in an instant. He smirked at the Dragon, moving away from the next attack in a blur. "Time for a staff meeting!" he called, and the Dragon had no time to react before the long bo staff's end hit his chest. While the Dragon was distracted, tumbling back, Donatello13 flipped around, charging the staff's other end into the man's chest. The man shouted out, desperately trying to stumble away. Donatello bounced back a little, swinging his staff in a wide circle, followed by blurs of purple light, before bringing it up to hit his target, right under the Dragon's chin.

The gang member soared straight up into the air, and Donatello13 followed him a second later with a skilled and powerful jump. The man's scared eyes widened in horror and Donatello13 waved at him, ten feet above the ground, before swinging the staff over his head in a blur of violet to meet the man's chest yet again.

There was the sound of bones snapping, the harshness of the impact rippling through the Dragon's body, and the world froze for a second - before the Dragon crashed onto the ground with astonishing force, leaving a crater of broken cement on the sidewalk under him. Donatello13 landed perfectly, and stood up to dust himself off, and immediately felt the crush of a giant wrench hitting his shoulder from another Purple Dragon, looking to avenge his fallen comrade. Donatello13 felt pain in his shoulder, and was slow to bring around his bo. The wrench was inches from his face when suddenly a blur of green and blue slammed into the man's body at full force.

Leonardo90 flipped backwards after hitting the man, stumbling a little before steadying himself. He winked at Donatello13, who was still staring in confusion and amazement at him, before running off to fight more. Leonardo90 hoped that by saving Donatello13, he could gain a bit of trust from the new turtle. So far, the 2013 turtles weren't taking kindly to the new group of unexplained duplicates. And the 1990, 2007, 2003, or 1987 turtles hadn't had the time to explain everything yet, but they needed to hurry if they were going to get the 2013 turtles on their side and go after Shredder again.

Leonardo13 saw a glimpse of his reflection grace the side of his katana before he attacked the Purple Dragon, his quick weapon, a blur of silver and blue, not near as sharp as the screams that split the night. The man fell to the ground, cradling his arm, and Leonardo13 now felt the steady pound of feet on the cement, the growls of frustration, and knew that another Dragon was approaching him from behind. The turtle flipped around, only to see the Dragon already on the ground, hopelessly blocking punches being thrown at him by Donatello07. Leonardo13 felt anger rise up deep inside him. These new turtles were unexplained and so sudden. Why were they here? What were their intentions? Leonardo13 didn't feel safe around them and if it meant protecting himself and his brothers from possible danger, he would do anything to keep these new turtles away. The blue-masked turtle let free a deep growl and charged Donatello07, who looked up at the swinging sword with wide eyes, backing away in an instant. Leonardo13 continued to pursue him.

"Dude, can't we talk this out logically?" Donatello07 said, narrowly dodging another swing. "We aren't hear to hurt you!"

Michelangelo07 was no more than a blur of green and orange as he moved around the Purple Dragon in a hectic, disorienting circle, his nunchucks thwapping against the mans legs, arms and neck for fractions of a second. The Dragon made a swipe for Michelangelo07, desperate to escape the painful confusion, but was instead greeted by a powerful kick to the chest. The man slammed into a drab brick building and slid to the ground, unconcscious. Michelangelo07 raised his arms and cheered in victory. "And Mikey does it again! Can anyone defeat this amazing, incredible, purely aston -" His self-praise was knocked short as something slammed into him, pinning him against the wall only feet away from the recently fallen Dragon.

Raphael13 leaned in close to Michealngelo07, his mouth drawn into a frightening frown. Raphael13's thin red mask was faded, stained, and rough around the edges, emphasizing the turtles' threatening white eyes. "Tell me what's going on!" Raphael13 hissed into Michelangelo07's face, his hands pinning the Mikey's wrists to the wall too tightly for any hope of escape. Leonardo13 guarded Raphael13, knocking away any enemy coming to close to the red-masked turtle who was getting answers about this unexpected group.

Michelangelo07 drew a breath before speaking. When he did, his voice was a little higher than usual, and he flinched at Raphael13's every move, as he began a rushed version of the story that they'd told every new group of turtles to join the group. The tale he hoped would convince the 2013 turtles to come to his side. To fight a common enemy.

Raphael87 flung a manhole cover like a frisbee at an ensuing Dragon, his hurt arm aching from the effort, but the manhole do much damage. Michelangelo87 heaved up a trash can and threw it at the gang member, knocking him down for a minute but not doing much else. "Even trash doesn't have any affect!" The Dragon continued to advance. Raphael87 and Michelangelo87 were having trouble with these serious, strong villains, as they were much more used to bumbling Shredder and unthreatening mutants. "Dude, we're in for!" Michelangelo87 said as they backed into a cold gray wall, the Dragon smiling as he raised his weapon. "Tell Kala I like her!"

Raphael87 shouted in response,"How? I'll be dead, too!" He shut his eyes tight as the man sniggered and the weapon came swinging down.

There was a sudden movement, and in no time the Purple Dragon lay on the floor, cringing in pain. Leonardo90 stood above him, and the turtle turned to look at Raphael87 and Michelangelo87, who were still pinned against the brick wall, Raphael holding Michelangelo in a Scooby Doo-like fashion. "Grow a backbone," Leonardo90 said before running off, kicking the downed Dragon once more for good measure. Michelangelo87 and Raphael87 shared a glance before Michelangelo quickly leapt away from his brother, sticking out his tongue. He rushed down the street, flinging his nunchucks in an attempt to regain his threatening demeanor. He was ashamed of how cowardly he'd been. After all, he was a ninja.

"Cowabunga!"

They were down to five Purple Dragons still fighting. The rain was pouring harder than ever.

"...and that's the end!" Michelangelo07 gasped, finishing his story he'd told to Raphael13. His wrists were sore from being held tight against the wall for so long. Finally, the red-masked turtle released his grip on Mikey and let him slump against the wall. Raphael13 regarded him in suspiscion for a moment before roughly holding out his hand for a high-three, which Michelangelo07 finished eagerly.

"I believe you, Mike," Raphael13 said in a gruff voice. "There ain't a better explanation for what's going on." A Purple Dragon charged behind him but Raphael13 knocked him out with a punch to the face without even looking behind himself. "I'll be glad to fight Shredder with you. I love any excuse to crack some skulls." He held out his hand and pulled Michelangelo07 to his feet. They were brothers now, not enemies.

Donatello13 suddenly ran to the middle of the group of four Purple Dragons, the only ones left. Michelangleo90 watched in awe as the purple-masked turtle began to switch on a device hooked around his arm. It looked technologically advanced but also a bit like a conglomeration of parts of several different devices Donatelo13 had crammed together. The turtle smiled like he'd already won the fight as the device lit up in a blue-ish glow.

Donatello13 raised his hand that was covered by the strange device and suddenly all of the Purple Dragons around him rose into the air six feet and then slammed back onto the ground full-force. Donatello13 was left smiling, in his hunched posture, at the four unconscious men around him. He brushed himself off and said,"All done." He looked over at Donatello87, staring in amazement. "Like my Gravity Gauntlet?"

"Don't act so smart," Donatello87 said, glowering in uncharacteristic jealousy. Donatello87 was angry at Donatello13 for trying to hit him with his bo staff a few minutes ago. "If I were you, I'd have used it long ago, when there were thirty Purple Dragons!" He folded his arms and tried to look haughty.

"Ah, but you are me," Donatello13 said, turning off his device. He had heard a great deal of the story Michelangelo07 had told Raphael13, so he had a pretty good idea about what was going on with these new turtles. "And my Gravity Gauntlet only works in close range and can't be used too much - it has limited power."

"I'd have that device working on solar energy rather than charged power, with an energy storage capacity able to hold enormous amounts of stored solar power for interminable amounts of time. That would greatly increase the Gauntlet's efficiency and usefulness." Donatello87 said this all very fast, in one breath. He wasn't entirely sure what he had said even made sense, as he was just throwing words at Donatello13 in hopes to top him.

Leonardo87 and Raphael90 approached the main group of turtles, who were all huddled around the two smack-talking Donatellos and yelling "Fight, fight, fight!" Leonardo and Raphael raised a white cardboard box into the air and cheered, "Look what we found!"

"PIZZA!" The turtles were distracted from the tension between Donatello87 and Donatello13 and rushed up to grab a slice. Leonardo87 explained finding the pizza box hidden in a dark alleyway, perfectly untouched, and the 2013 turtles said through full mouths that they found pizza like that a lot. It was odd, but the pizza seemed to restore their energy lost in the hard fight. Michelangelo07 took his chance in the calm moment to explain the story about the mysterious new Shredder and the multi-verse in a better, less rushed, way, the new turtles nodding as they followed along in the strange retelling of events.

"So, let me get this straight," Leonardo13 said once Michelangelo07 finished. "There's dozens, possibly hundreds, of lives at stake here in different dimensions, and your best plan to handle the threat is to go on some wild goose chase through every dimension until you find the Shredder responsible?"

Donatello03 shrugged. "Yup. It's the only thing we can do. There's no way to know for sure where Shredder is." Leonardo13 groaned in exasperation but didn't say any more.

"So, are you guys willing to fight Shredder alongside us before he destroys a dimension, and maybe even Turtle Prime?" Leonardo90 asked the 2013 turtles as he finished off his slice.

"Of course we are!" Michelangelo13 cheered. "I can meet all the other Mikeys and we can hang out and eat pizza and finish each other's - "

"- Sentences," Michelangelo87 finished, smirking. He plucked out the Trans-dimensional Portal Stick and opened up a portal to another random dimension. The turtles didn't even look at the image as they all rushed in, in their rush to catch up to the Shredder.

-1987 dimension-

Splinter87 ran at Shredder at full-speed, his feet flying across the floor. The rat leapt into the air, his eyes level with Shredder's, and flung his feet at the man's chest. Shredder stumbled back and Splinter landed on his back on the floor, quickly leaping up. Splinter was skilled, but it was obvious the years had began to wear on him, slowing him down, stealing his energy. He didn't move in time to get away from the Shredder's grasping hand. The menace pulled him into the air by his ankle, and Splinter could just imagine the menace smirking behind his metal face mask as the rat struggled to free himself.

Shredder began to punch Splinter in the chest, and the rat was left helpless to stop the persistant jabs as pain flared through his body. Any other day, this would have been the part where Splinter gave up, his exhaustion unbearable, but the rat reminded him that this strange new Shredder had killed his pupils, the turtles.

His sons.

New energy flared up inside Splinter, consuming the sadness that had clouded his mind. He would avenge his sons, even if it killed him. They had been what kept him company for so long when the rest of the world had abandoned him. They never gave up on him, and he never gave up on them, training them over the months when they'd gone from hidden freaks to city sensation. Splinter wracked his brain for a way to escape, as the villain began to monologue about avenging someone known as Tang Shen. Splinter smiled lightly when he saw the large, ugly gash running down Shredder's right leg, ripping straight through the cloth, which was covered with dried blood.

Splinter flicked his wrist and three shurikan, sharp and shiny, slid into his furry palm. A ninja is always prepared. He threw them precisely at the gash and one became stuck in it, embedding itself deep into the infected injury.

The Shredder reeled back, screaming in agony. Splinter fell to the floor and caught his breath. The villain leaned down and tugged free the throwing star lodged in his deep cut, and immediately threw it towards Splinter.

The rat slid away quickly, throwing out his leg in hopes to trip Shredder. He succeeded and the menace fell to the ground, hard, his heavy metal armor clanking. However, Shredder was quicker to his feet than Splinter, and he began to pursue the rat. Two foot metal spikes slid out from his wrist cuffs, cutting the air, and Splinter backed away from them, into the kitchen of the Lair. His fingers soon found themselves pressed against the wall, his tail snapping against the bricks in a nervous beat as Shredder approached and stood right over him. There was a flash. The two metal spikes were pressed against the wall on either side of Splinter's neck, barely an inch away from his skin. Shredder raised his arms and Splinter rose higher, to eye level.

"Goodbye, Hamato Yoshi." A new metal spike, shaped like an arrow, shiny and unbelievably pointy, slid out from the middle of Shredder's metal cuff. It was barely a centimeter away from Splinter's neck, ready to puncture it. Splinter went cross-eyed trying to keep the point of it in his view. The rat's heart beat fast and the two other metal spikes holding him in the air dug into his chin, drawing blood. "Any last words, freak?"

Splinter drew a breath, his expanding throat barely nicking the new blade. "I die with honor. My sons died with honor. You will not."

"Very well." The blade slid even closer, and Splinter could feel a small break in his skin; he drew his last breath, savoring it. All of the sudden, the ground shook with unexpected force, throwing the world off balance. The table in the kitchen fell over with a crash, pizza sliding off onto the cracking floor. The television in the other room fell straight to the ground with a crash, the glass shattering. Shredder veered to the right, his metal spikes separating from Splinter's neck. The rat slid to the ground and struggled to keep his balance, drawing a huge breath he never imagined taking.

"What is that?" Shredder yelled, his eyes searching the room, and Splinter noticed one side of the Shredder's face was badly burned.

"Do you not recognize the sound of the Technodrome, Shredder?" Splinter yelled. He ran towards Oroku Saki, as the shaking ground threatened to knock him down once more. The rat began to kick and punch, shouting out in anger, not planning to give up until this menace paid for the death of Leonardo, Raphael, Donatello, and Michelangelo.

Shredder plucked the rat from the ground, stopping the him before he could attack his vulnerable wound again. With Splinter in his hand, not currently a threat, Shredder was free to think. He remembered the Technodrome, the huge flying ship the Kraang had constucted. In his dimension, it was stuck in the bottom of the ocean, but this Technodrome was not. It was moving, causing the ground to shake from its immense size. If this Technodrome was anything like the one Shredder remembered, it had portals. Portals.

"I cannot let it get away!" Shredder called out, running out of the Lair in the general direction of the noise, struggling to find his footing on the ground snapping beneath him, threatening to swallow him up. Splinter still flailed in his fist, fighting for freedom.

-TMNT Anime Universe- (This is a two-part anime - titled Myūtanto Tātoruzu: Chōjin Densetsu-hen, or Mutant Turtles: Superman Legend in English - exclusively released in Japan in 1996. It's really goofy and I recommend you watch it online (with English subtitles) to understand this part of the story better. I just thought it'd be fun to include these turtles. The anime turtles will be referred to with 96 at the end of their names.)

Leonardo13 tripped as he walked through the swirling portal into a new world. He groaned as he pressed himself to his knees, the rest of the turtles stepping out of the portals and converging around him. The blue-masked turtle was shocked to see that the ground was not hard cement, but grass, blowing in the breeze from the portal. He didn't remember a time in his life when he'd actually touched real grass, since his entire fifteen years had been spent in the skyscraper-filled concrete jungle, lit by neon lights and blaring advertisements on Main Street. He stared down at the green plant like it was a mystery to him.

"This isn't New York," Michelangelo90 said, scratching the back of his head in confusion. The portal closed as Raphael87 walked through last. "Hmm...did we take a wrong turn on our way here?" Michelangelo87 rolled his eyes and stuck the Trans-dimensional Portal Stick back into his belt. He walked forward and examined the area, his feet feeling strangely out of place in the soft grass. It was a vast field, with trees lining the edge and beginning a dense forest.

"Don't you recognize this place, Mikey?" Donatello90 said, addressing the orange-masked turtle of his dimension. "This is Japan. We've been here."

"Yeah, but we were in the country hundreds of years ago. How do we know this is Japan?" The rest of the turtles exchanged confused glances, having not heard of the 1990 turtles' time-travelling adventure. Michelangelo90 looked around closer and did find similarities in the environment like those of the Japan he remembered. He shrugged. "Either this is Japan or we travelled to a New York of 1632! Just look at the wide, open spaces!"

"It's Japan," Leonardo90 confirmed briefly, scowling as his orange-masked brother pretended to prance through the bright green field, humming off key. Leonardo90 leaned against an old, withered tree with bunches of pink flowers weighing down the scrangly branches and began to meditate, searching for answers.

Michelangelo87 was far out now, a few dozen yards away from the rest of the turtles, who were still looking around his awe at their new surroundings. Donatello03 watched the short turtle continue to shuffle through the tall grass, and the purple-masked turtle noticed something even farther off in the distance. It was a pile of rubble, a huge conglomeration of gray blocks and blue roof tiles that was a stain against the rest of the beautiful green clearing. He could just imagine it as a once proud Japanese structure, one so tall that it graced the bottom of the clouds. Donatello03 swallowed hard. What had caused the building to collapse?

"Hey, is it just me, or do you guys see those things way out there?" Donatello13 said, pointing off in the direction of the rubble, squinting against the sunlight he was unaccustomed to.

"You mean the ruins?" Donatello03 asked, leaning in a few feet closer as if that would give him a better view.

"No, not exactly that. Don't you see the things moving in the rubble?"

"I do!" Michelangelo03 said. The orange-masked turtle was prancing around the field with Michelangelo90, like the goofball he was. He paused in his movement and shouted out to Michelangelo87. "Hey, watch out!" He began to run towards his dimensional duplicate, ready to protect him in the case something bad happened. It was hard to tell what the things moving in the rubble were.

Seven forms emerged from the dust cloud surrounding the depressing ruins, walking in a straight and rigid line. Even from far away, Raphael90 could see the confusion etched into their expressions as they squinted at the huge group of turtles spread out around the field.

The first form was a young man, lean and muscular, clothed in a simple black ninja outfit, easy to spot in the bright field. The next was a rat, none other than Splinter. The 1987 turtles gasped, shocked at how similar this Splinter looked to their own. The next person was April O'Neil, her red hair shiny and her yellow jumpsuit noticable against the dark rubble behind her. The next four forms were obviously turtles, but something was off about them. The 1990, 2007, 2003, 2013, and 1987 turtles ran up to meet them, able to tell what was different about these four turtles from a close distance.

First off, all of the 1996 turtles were clothed in pants, belts with initials strung around them at the top. Metal clasps stretched from under their left arm to their right shoulder, again displaying their initials. More metal armor ran down their arms and knee-pads, color-coded to match their masks, sat over their pants at the knees. Even under all of the strange clothing, they looked remarkably similar to the 1987 turtles.

Raphael87 stood in front of Raphael96, raising an eye-ridge as he noted just how similar an experience this was as to looking in a mirror. He turned behind him, addressing the rest of the 1987 turtles. "Guys, I think we've had our identity stolen." The new April O'Neil leaned in close with a video camera, recording everything for her news station. Raphael87 pushed the camera away.

"Anata ga daredearu," said one the new turtles - Michelangelo.

"Ana - wha?" Michelangelo13 said, scratching his head. "Repeat, please. This time, a little bit slower."

"An..ata...ga...dare...dear...u," stretched out Michelangelo96, leaning in close. Michelangelo13 shook his head, still not understanding.

"Baka," said Leonardo96, huffing and folding his arms. The other turtle groups had no idea what he said but it didn't seem to be a compliment.

"Uh, oh," Leonardo03 said, in sudden realization. "We've got a language barrier. These turtles are speaking Japanese!" He slid his hand across his face in exasperation, struggling to remember some basic Japanese Splinter had taught him. The 1996 turtles stared in confusion and anger.

"I know a bit of Japanese!" Donatello90 said, raising his hand eagerly. He stood in front of Leonardo96, who scowled at him. "Uhh...Chevy Nova. Merīkurisumasu. Watashi wa kirinda." He had no idea that he had just wished Leonardo96 a merry Christmas and called himself a giraffe.

Leonardo96 stood stock-still, struggling to keep a straight face for several seconds, before he broke out into a huge round of laughter, falling back onto his shell as he hollered, "Sumāto ichi no tame ni ōku!" Donatello90 watched in confusion.

"I'm no expert, but I think he just said 'So much for the smart one'. What you said in Japanese must have been pretty hilarious," Leonardo03 said, smirking a little, watching as his Japanese dimensional duplicate rolled in the grass in laughter, while the other 1996 characters giggled as if to some inside-joke.

Michelangelo96 caught his breath, grinning widely, and spoke. "You silly turtles. We speak English!" He bowed to Michelangelo87, apologizing for having fun with the supposed 'language barrier'. The 1996 turtles didn't seem overly startled by the new turtles, but they probably dealt with stranger stuff everyday.

"I'd like to know why we come to Japan to fight the Shredder and then once we defeat him, we find this huge crowd of more mutant turtles!" Donatello96 said, turning to the man clothed in black on his right. "Do you know what's going on, Kinzo-san?" The man merely shook his head, looking a little shy as April O'Neil pressed her camera in for a close-up.

"Smile!" she encouraged him. She couldn't tell if he actually did, as most of his face was covered by his ninja mask.

"All right, we've wasted enough time here," Donatello07 said, as Michelangelo90 once again began to prance around the field, this time with all the rest of the orange-masked turtles, humming loudly over Donatello's words. Donatello07 turned to Donatello96. "There is a Shredder threatening the lives of all of us. Are you and your brothers willing to help us defeat him?"

"If we get pizza!" Michelangelo96 called out. "We're starving!"

Leonardo96 leaned in on the conversation, feeling as leader he should have some say in this. "Do you really think you guys can't handle your own Shredder? We just fought a huge Metal Devil Shredder - just the four of us and Kinzo-san!"

Michelangelo07 stopped dancing and stared at Leonardo96, wondering if heard him right. "Metal Devil Shredder? That sounds like a wicked cool video game boss!"

Leonardo96 folded his arms in contempt. "Yes. Metal Devil Shredder. We beat him, Bebop, and Rocksteady up really well and then he swore at us and ran away through a portal."

"Leo-san," Donatello96 said, addressing his angry brother. "I think we should help them. They should explain to us what is going on and then we should go fight this Shredder. Lives are at stake, he said. And I'd like to know what's going on."

"I agree," Splinter96 said. "You cannot deny the voice of reason, Leo-san."

Leonardo96 huffed. "Fine...Kore wa yoi yoi."

Michelangelo13 pushed Donatello07 away to stand in front of the 1996 turtles. It was his turn to tell the story, since most of the Michelangelos had already had their chance to. "All right. Once upon a time..." Raphael90 was quick to hit him over the head so Michelangelo13 began the story again, reminded of how serious the situation was and that now was not good for time-wasting jokes.

Forgive my Japanese if it's bad. Google Translate isn't too reliable.

In case you didn't know, the rest of the turtles joined the anime turtles directly after the events of the second anime episode. The collapsed building mentioned in the chapter fell down at the very end of the episode.

I only recently watched the anime episodes a few days ago, to get a feel for these turtles so I could incorporate them into the story. The two episodes were really just big commercials for Japan-exclusive TMNT toys but they are pretty good for what they are. I thought it funny that this anime was very similar to the 1987 cartoon but the characters swore a lot, especially Shredder. The anime turtles may not be very popular or recent iteration but I find they are a nice addition to the story, being so different from the rest of the versions.
