Dragons

"Woah!" Mikey exclaimed as something dark and fast flew past him, the velocity of it pulling him towards it but Mikey withstood the harsh pull, his feet planted firmly on the floor.

His excitement skyrocketed when he noticed the silhouette of the nearly invisible creature against the far away city lights.

"Dude, did you see that?! It was a Dragon!"

"Mikey, watch out!" A couple of lasers were deflected by a bo staff as Donnie got between the Kraang-droid and his younger brother, impaling the naginata blade into the bot's head. It dropped with a few sparks and a brain hopped out of it, crawling away as it squeaked.

"You're supposed to be covering my back, Mikey. Not the other way around."

"That was so awesome! I saw a huge, black dragon!"

"Are you even listening? We gotta close these random portals." Donnie chided before turning his attention back to the alien computer, "And dragons don't exist."

"But I just saw one! It was huge and black and very very fast! I wonder if its cute too."

"Must have been an alien or a mutant."

"It wasn't, Dee. I swear I saw it."

The other turtle ignored him, his attention focused on turning off the portals while Leo and Raph were fighting off Biotroids on another floor of TCRI, trying to prevent them from reaching Donnie and Mikey.

"The others would have believed me." Mikey mumbled in resignation and extended his kusarigama, launching himself to jump upon the next wave of Kraang-droids.

"Since when did they get so tough?" Leonardo panted as he slashed at the giant arm, finally managing to cut it off.

"Heck if I know." Raph dodged the lasers which were being shot at him and he suddenly yelped, scrambling to dodge a cute, teddy bear sized turtle having a squirrel tail.

"SQUIRTLEEEEE! Squir Squir Squirtle! Squirtle Squirtle!"

It ran past his legs and jumped into another triangle which had appeared seconds ago. It was followed by another teddy bear sized creature which was yellow in colour and had long pointy ears and zigzag tail.

"Pika pika pi! Pika!

Raph watched them incredulously for a moment before shaking his head and punching a Kraang-droid.

"I'ma go looney if this continues any longer. Donnie needs to shut down these portals and redirect these things back to their dimensions."

A loud, guttural growl sounded from above them and both brothers let out alarmed shouts before jumping to the side as a huge dragon covered in flames landed where they've been a second ago.

It raised its blazing head and glared at the two turtles who could only stare at it with wide eyes.

In another dimension, a few kids sat around the LCD screen as they watched their favourite cartoon on Nickelodeon. A pink triangle suddenly appeared in their room and they gasped in excitement.

"A Kraang Portal!"

The kids scrambled up and rushed towards it but it disappeared before they could reach it and they tripped over each other.

"Awwwwwwww!"

They whined collectively and one of the boys looked back at the screen before perking up, "Guys Look! Raph is about to get turned into a turkey!"

The kids forgot about the portal in favour of watching the rest of the episode and sat around the screen once again.

"Bashing all the Kraang-droids

Passing all the hurdles!"

Mikey sang as he flipped from one place to the other, incapacitating every single Kraang he ran across.

"That's the way the ninjas go

Pop goes the turtle!"

Donnie was typing on the touch-sensitive panel while trying his best to drown out Mikey's singing. It was giving him a headache.

"Up and down the building walls

Around 'n around the portals

That's the way the ninjas go

Pop goes the turtle!"

"Mikey..." Donnie started calmly, his voice getting louder with each syllable, "Would you please just SHUT UP!"

The youngest turtle stopped singing immediately, humming the poem to himself instead as he flipped about and continued to fight, covering Donnie's back.

The genius sighed, greatful for the peace and the fact that he could now focus on the task at hand. After a couple of minutes of typing, he shouted in triumph and pressed a button on the side.

All the pink triangles began to disappear, as did most of the creatures which didn't belong in this dimension.

Mikey and Donnie made quick work of the rest of Kraang-droids before rushing inside an elevator to get to their brothers on the upper floor. As it moved, Donnie took out his T-phone to text April and in a few seconds, the elevator stopped, its doors sliding open with a ding.

"What took you guys so long?" Leo's asked while subtly checking them over to make sure they weren't injured and relaxed a little after seeing only some superficial bruises

"Mikey was fantasising again." Donnie stated flatly without looking up from his T-phone as he walked forward and ran into the Michelangelo's shell, who had frozen on the spot.

"Mikey, why did you..." His voice trailed off as he gazed up and saw what his younger brother was staring at, "Wow..."

There in front of them sat Raphael, a huge smile on his face as he kept stroking and patting a dragon who laid next to him with its head in Raph's lap.

Shaking himself, Mikey finally noticed that Leo had been sneakily recording the whole thing on his T-phone and he skipped next to his eldest brother to watch from up close. That movement broke Donatello out of his petrified trance.

"W-Wha- How? But it- Huh?"

"We don't speak 'Malfunctioning Robot', Donnie." Raph teased with a smirk as he gently stroked the dragon's neck, "Try again in English."

"How?!" He gestured incredulously at the huge, dangerous beast who was acting like a kitten while rubbing its head against the hothead's hands.

"He's Raph." Leo shrugged, though the smile on his face gave away the fondness he was feeling, "Snow White, remember?"

"Don't call me that!"

Mikey beamed at the whole thing, "Dude, this is epic!" Then he turned to hop and dance around Donnie in circles, "I told you dragons exist! Haha! I told you so~ I told you so~ I told you so~ In your face! Hahaha!" Mikey kept singing while dancing around a baffled Donnie.

The other two turtles chuckled and after sharing an amused look with Raph, Leo pointed the camera towards their younger brothers, recording Michelangelo's childish antics and Donatello's sputtering.

They all stopped what they were doing when a black dragon suddenly flew in and landed, looking exhausted after having to carry four people– three of them being vikings.

One of the two huge men jumped off the dragon and held up a hysterically laughing Casey towards the four surprised turtles.

"Does this belong to you?"

They blinked and shared a wide-eyed look.

Mikey reveled in the fact that he was right. Again. This black dragon truly was cute, with its retractable teeth and adorable green eyes and playful nudges. He completely forgot about teasing Donnie and played with Toothless instead, Leonardo joining him as well. Afterall, they both loved dragons.

"A Monstrous Nightmare is the angriest dragon I know of. It's quite impressive that you tamed one so easily." Hiccup adressed the red-masked turtle who was sitting cross-legged while rubbing the dragon's head, a soft smile gracing his features.

"Thanks."

"Raphie loves animals!" Mikey supplied helpfully from above Toothless' back while Leo scratched the nightfury under his chin, making him purr blissfully.

Boy, this dragon was adorable!

Donnie, on the other hand, had started working on locating the dimension these dragons came from soon after the turtles had introduced themselves to the three humans; Casey was currently entertaining two of them.

It took the genius turtle a few minutes in which his brothers busied themselves into playing with the winged reptiles but he finally found the correct dimension and after a few clicks, activated the portal leading to it.

As they walked through the sewer tunnels after sending those vikings and dragons back to their dimension and grabbing some pizza, Leo wouldn't stop fanboying. He was super excited and kept going on and on about seeing an actual dragon and playing with one.

Donnie had strolled ahead and Raph thanked his lucky stars that Mikey had his mouth full with pizza and wasn't talking, being too busy relishing the cheesy, hot goodness.

"...they loved getting scratched under the chin and the nightfury's wings were actually bigger than the other dragon! But he could flame up and..."

Raph rolled his eyes at his dorky big brother and tried to block out the constant rambling. It was all for nought though, as Leo was suddenly in front of him, grabbing his shoulders and shaking him back and forth.

"And they were highly intelligent too!"

Raph covered Leo's mouth to stop him from speaking any further.

"Bring your fanboying down a notch. Will ya? Your'e acting worse than Mikey."

Leo tilted his head, his blue eyes wide. He looked like a kid at that moment and the red-masked turtle wondered if he was somehow possesed by Mikey. He sighed and strolled ahead, his brother silently falling in step next to him.

They walked in comfortable silence for a few minutes before Leonardo spoke again, "You are really good with animals, y'know."

Raph grunted in response, inwardly smiling at the unexpected praise. The blue-masked turtle grabbed his arm and turned him so they faced each other.

"Thanks for saving me back there."

Raph grinned and threw an arm across his brother's shoulders as they resumed walking towards home.

"That's what brothers are for."

When the guys reached the lair and exuberantly reported to their father about the mission gone successful, they never realized how lucky they've been that a TMNT fan hadn't stumbled out of one of those portals.
