Chapter 1: Tornado

A few days had passed after the junkyard incident, and Donatello was back on his feet once again, with only minor scars left behind. Now he, Leonardo, Raphael and Michelangelo were heading over to April's apartment in the dark of the night to see how their human friend was doing.

However Raph and Mikey, as usual, were goofing around as they leapt across the rooftops with Mikey teasing his older temperamental brother about how he was in reality a 'great big softie'. Finally having enough, Raph growled as he charged for his younger brother and the two rolled across the rooftop in a pile of limbs. Donnie ran over to make them stop, but only ended up being dragged into the fight himself.

Leo came to a stop as he rolled his eyes with an irritated growl. "Guys!" he hissed. Upon hearing their leader, the three immediately stopped trouncing each other and glanced up at him. Leo folded his arms firmly across his chest as he glared down at them. "What are we?"

All three turtles stood up side by side, all wearing bored and slightly irritated looks. "Ninjas" they spoke in unison, their tone suggesting they had had this conversation many times previous.

"And what are ninjas supposed to be?"

"Quiet"

"And what are you not being?"

"…quiet" they sighed collectively.

Leo nodded, "So what are you going to be from here on out?"

All three turtles rolled their eyes in unison. "Quiet."

Leo nodded again in approval. "Good. Then let's keep going," he commanded as he ran and leapt to the next rooftop, with his brothers closely in tow.

Mikey smirked and muttered "softie," under his breath.

Raph snarled, but for a change, he chose not to retaliate.

Within less than half an hour later, they had reached April's aunt's apartment. Donnie knocked on the window and grinned as April approached the window with a smile and let them inside. Her aunt was out of town again that night, so it was safe for them to move around freely without fear of being discovered. As the turtles moved inside, Leo leaned against windowsill, Raph crouched on her bedside table, Donnie leaned on his Bo staff next to April's bed and Mikey sat right next to April on her bed.

April gave a long contented sigh. "It's good to see you guys. It's been getting really quiet without you here to entertain me!" she laughed.

Raph chuckled. "Well, sorry, your highness," he mocked with a short exaggerated bow.

Donnie chortled and joined in the joke, "Our humblest apologies indeed, Miss O'Neil" he smirked.

Leo laughed and bowed deeply, "How may we entertain you this night, m'lady?"

Mikey simply stood up and sang, purposely out-of-tune, "Oh let meeeeeeeeeeeeee entertain you!"

The room became filled with laughter. Over all his brothers, Mikey could hear April's laughter, making him feel so warm inside seeing her happy like this. They had all come to see her as the sister they wished they had (apart from Donatello of course, who wished for it to something more than just that). She was the only human that had been able to accept them for who and what they were, and even befriend them for it. Indeed, she had one of the purest hearts they had ever seen.

And April, for her part, felt the same way about her strange, loving mutant family.

Suddenly, their laughter came to a stop as the whole room began to shake, books falling from shelves and lights flickering. Startled, the turtles instantly formed a protective circle around April. "Whoa! What's going on?!" she cried.

"It's an earth quake!" yelped Mikey as he clung to Donnie's arm in fright.

"No, It can't be an earthquake, the magnitude would probably be stronger than – Mikey, let go of me!" exclaimed Donnie, trying to shrug off his clingy brother. He was embarrassing him in front of April!

"Well then if it's not an earthquake, then what the heck is it?" Raph growled as he tried to steady himself by grasping Leo's shoulder.

Leo placed this hand over Raph's wrist and snaked an arm around April's wrist to secure the two of them. His gaze suddenly shifted to look out window as he saw something zoom past.

Just as it flew by, he could just see a distinct colour of familiar purple and metallic grey.

As the tremor finally stopped, and the lights finally returned to normal, Leo frowned deeply. "Guys, I think that was Kraang ship that just went past."

All eyes went wide as they all rushed towards the window and peeked out, craning their necks to get a better look. Indeed, there was a Kraang ship flying into the distance at high speeds, clearly in a rush for something. But whatever it was, being the Kraang, it could not be good.

"Donnie, exactly how fast do you think it would take for us to reach that ship on foot?" Leo addressed his taller brother without tearing his eyes away from the ship.

"Approximately five minutes, forty seconds and three point five milliseconds" Donnie replied instantly without batting an eye.

"What about if we tried using the Patrol Buggies?"

Donnie hummed in thought. "…slighter shorter, but only if we leave now."

"Then that's what we'll do" he said as he turned to April and looked her straight in the eye with resolve, and placed a hand on her shoulder. "April, you better head to the lair in case the Kraang come back and find you here. We'll go check up on whatever they're up to now."

Though she really hated running away, April nodded firmly, knowing it was only for her safety that she hid for the time being. If they were ever to defeat the Kraang and find her father, it would do nothing if she too were captured.

Leo then turned to his brothers. Mikey saw that familiar fire in his eyes again, and could not help but be filled with pride for his older brother.

"Let's move, guys" he decreed determinedly. His brothers nodded and leapt one by one out the window.

Michelangelo stopped for a moment to give April a quick hug and thumbs up. April smiled and headed out of the door to head for the lair as Leonardo had told her. But even as she left, she could not bite back the feeling something bad was going to happen to them that night. Whenever they went up against the Kraang, they always seemed to walk away victoriously – well, with a few minor cuts and bruises. But something in the back of her mind told her that the turtles would lose something in the battle that night.

She silently prayed for her boys' safety.

Not long later, the turtles were in hot pursuit of the Kraang ship in the Patrol Buggies, racing rapidly through the darkened streets. "Step on it Leo! We're gonna lose 'em!" Donnie cried.

The Kraang ship took a sudden sharp turn to the left. Leo gritted his teeth. "Hang onto your shells!" he warned as he swerved the Patrol Buggies around to the left. His brothers yelped in surprise, gripping to the sides of their cars to keep their balance.

Aside for Mikey of course, who raised his arms in the air and cried out jubilantly. "Wooohoo! Yeah! This is awesome!"

"You think everything's awesome, numbskull!" Raph retorted, still griping the sides of his buggy to keep his steadiness.

"What's not to think is awesome?" Mikey retorted with a grin, "Because when you think something is awesome when something awesome happens, an awesome feeling washes over you and then you feel awesomely awesome yourself! Awesome, huh?"

"Wait – what're you – what?!"

"Mikey! Raph! Stay focused! We're closing in on the Kraang hideout!" Leo snapped, further silencing his two bickering brothers as they gave chase to the Kraang ship.

Eventually, the Kraang ship slowly came to a stop over an old warehouse building as a door on the roof slid open, allowing the ship to gradually descend into it. The door slid closed again, sealing off any possible entry through there.

The turtles came to a halt and climbed out of the buggies. They unsheathed their weapons as Leo surveyed the area. When he was sure they were not being watched, he turned to Donnie.

"Donnie, you see any openings?" he asked in a loud whisper.

Donnie's dark red eyes scanned the old structure intensely for any hidden openings. A silent moment passed before he spotted something. "There!" he piped up, pointing towards the roof. "The side of the roof has a big gaping hole. It'll probably be big enough for us to fit through!"

"Then let's stop wasting time and let's go already!" Raph growled as he started to bound up to the rooftop to get through the crack Donnie had pointed out. Mikey was quick to follow his older brother.

"Wait for me! You're not the only one who gets to bash some Kraang, dude! You always hog all the beat downs!" Mikey called up to his red clad brother as he scaled the old building.

Leo and Donnie shared a flat look. Leo sighed and rolled his eyes. Raph's fighting attitude was admittedly at times admirable, but it was going to get him killed one day.

With a long suffering sigh, he leapt up and followed Raph and Mikey with Donnie close behind. All four silently squeezed through crack; Mikey going through first, since he was the smallest, followed by Raph, Leo and finally Donnie.

Ninja instincts kicked in as they moved through the shadows across the support beams on the celling. Only the whites of their eyes could be seen as they peered down at the Kraang operation buzzing below them. Dozens upon dozens of Kraang robots were gathered closely around circular platform that began to glow as it sparked to life.

Donnie recognised the design, his eyes widening as he let out a quiet but sharp gasp. He turned to Leo.

"Leo, I think they're making another Kraang portal!" he said in a loud whisper, "This one's slightly minor in construction and design, but from all that power it's giving out, I wager it can still generate the same magnitude of dimensional vitality!"

His three brothers raised confused brows at him as they stared at him in blank silence.

Donnie pouted. Once again, they had no idea what he was talking about. Typical.

"I think it can still generate the same amount of energy as the other portal in the TCRI building," he spelled out for them, "and by the looks of it, I think they're gonna test it out now."

Leo nodded firmly in understanding before turning to glance at his brothers. "Well, we're not gonna let that happen. Ready guys?"

They all nodded collectively.

"Then let's do this!"

Wasting no more time, the turtles leapt down, with their weapons drawn and ready. All Kraang turned abruptly and aimed their guns. "It is the ones who call themselves the turtles. Kraang must destroy them so they do not interfere with the plan which is the plan to –"

"Just stop talking and start fighting!" Raph mocked as he charged headlong into the Kraang, his brothers close behind. The turtles plunged into battle, swiftly taking down numerous Kraang droids within moments.

Leo watched his brothers from the corner of his eye. Raph was viciously tearing Kraang apart with his Sais. His temperamental brother was always pumped up and ready for a fight.

And when he fought, he always did so without mercy.

Donnie swung and swiped his Bo staff through several droids before using it to launch himself over their heads. Leo could clearly see the screws turning in his head as he calculated his best means of getting out of the circle. His third brother always had a tendency to overthink things.

But that was what made Donnie…well, Donnie.

Mikey was swinging his nunchaku, smashing Kraang heads and using his Kusarigama chain to wrap and swing a Kraang droid around, knocking over numerous others in the process, grinning all the while.

He always enjoyed a good 'Kraang Stomping'.

With confident grin, he plunged back into battle, knowing that his brothers would be just fine. For now, that is.

The Kraang numbers were becoming fewer with every passing second. It seemed as though the turtles were once again going to win this battle. However, it was then that one Kraang decided to fully activate the miniature portal, pressing a series of numerous buttons as it whirred to life.

Donnie promptly noticed this, but was too tied up with one of the other Kraang bots to do anything about it. Knowing there was no time left, he quickly turned to Mikey and Raph. "Mikey! Raph! Shut down that portal!" he called.

Raph and Mikey shared a grin, "Done and done, Don!" Mikey laughed.

With that, Raph reached out and grabbed Mikey's hands and begun to spin him around, lifting him off the ground as they spun faster and faster. Mikey began to cry out in laughter as the two spun in place.

"Ready, Mikey?!" Raph called with a grin.

"Let her rip, dude!" Mikey hollered with a freckled beam of his own to rival his brothers'.

And when the time was just right, he released Mikey, sending the orange turtle flying into the air like a missile, whooping in pure delight. He flipped out Kusarigama blade as he came down upon the portal, grinning all the while.

"BOOYAKASHA!" he hollered gloriously as he landed on the miniature portal, impaling it with his short blade.

The portal began to spark and crackle as the blade pierced its circuits. Mikey's eyes widened slightly as the machine began to heat up. All fighting came to a halt as everyone stared at the brightly glowing portal.

"Uh oh..." Mikey whimpered.

The machine emitted a strange high pitched whirring sound, getting warmer and warmer. Noticing what was about to happen, Raph charged and grabbed Mikey, pulling him away from the portal just as it exploded. Florid energy poured from out from the destroyed machine, growing larger in size as it began swirling and spiralling as if it were a vicious tornado, sucking anything and everything into its dimensional vortex.

Several Kraang robot bodies were sucked into it, the alien brains within them leaping out and screaming and sliding away desperately for cover. Large chunks of brick, metal and many heavy crates and barrels filled with who-knows-what were also being pulled inside.

The turtles themselves clung desperately onto the support pillars for dear life, none of them wanting to find out what was on the other side of that portal.

"Donnie! What's going on?! Why is the portal turning into a cyclone?!" Leo shouted over the noise.

"I-I don't know!" Donnie shouted back in response, "Maybe the dynamism being contained inside the portal was still marginally unstable when Mikey impaled it!"

"Is there any way you can get to it and shut it off?!"

"Are you kidding me? The pull of that vortex is gonna get strong enough to level this entire warehouse eventually! We've gotta find a way to get out of here before we all get sucked into another dimension! Or considering the amount of unstable energy, get sucked into oblivion!"

"Great! Just great, Donnie!" Raph bellowed, gritting his teeth and tightening his grip on the pillar as the portals' pull became stronger, "could this get any worse?!"

It was then that Mikey's grip slowly began to slip on the pillar. Try as he might, he could not hold on for much longer as the pull of the vortex became too much for him. "Oh no," he begged, "Oh please no, no, no, no, no, no, no –"

His fingers finally slipped as he was lifted off his feet and pulled towards the spiralling vortex with a scream.

"MIKEY!" Leo cried as he released his hold on the pillar and launched himself after his little brother and grabbed his outstretched hand. Donnie leapt up and grabbed Leo's ankle. Raph grabbed Donnie's belt as he used his other arm and clung to the support pillar.

Leo held Mikey's hand with all the strength he had left in him as his mask tails whipped and lashed at his face. The strain was becoming stronger, and it threatened to rip his very arm out of its sockets, but he refused to let this threshold into hell take his brother away from him. Even as he heard a bone pop in his shoulder and was unable to hold back his cry of pain, he still held on.

He refused to fail his family as a leader and as a brother.

Mikey in turn desperately hung onto his brothers' hand. He did not want to die. He was not ready to leave his family behind. But the vortex had other plans as its pulls were becoming too great for him or his brothers to hang on any longer.

His grip began to slip.

"No! Mikey, hang on! You've gotta hang on!" Leo pleaded, trying to regain his grip, but it was useless. It was as if the portal was purposely dragging him into its spiralling vortex, and would not let up until it had him.

He could not let it. He would not let it.

Mikey tried. He really did. But it was just too much. He could even see the pain in his brothers' eyes as the bone in his arm came slightly loose from his shoulder. "Leo...I-I can't!" he cried.

"Don't let go, Mikey! You can do it!" cried Donnie, readjusting his hold on Leo's ankle to gain a better grip. He was right when he said the portal could level the entire building; he could see the very floor being ripped from the ground and sucked into the whirlwind. But he would defy the laws of science and logic itself it he could keep his brothers safe.

"If you let go I swear I'll kick you out of your shell, Mikey!" Raph bellowed, grinding his teeth together as he strained to keep his hold on the pillar. Like Donnie and Leo, there was no way that he would let any of his brothers go.

He would rather die himself.

Leo strained with everything he possessed to hang onto his little brother, but he too was failing. The pull was too strong and the painful throbbing in his arm was weakening his hold.

"Leo, Raph, Donnie, I love you guys! Tell April and Splinter I love them too!" Mikey wailed, tears dripping down his face. "I'M SORRY!"

His fingers finally slipped away from Leonardo's. He shrieked as he was dragged into the tornado.

His brothers watched in horror as their baby brother was ripped away from them and sucked into the vortex.

"NOOOOOOOOOOOOO!"

Mikey kept screaming as he was rolled around and around within the continuously spinning vortex. He could hear his brothers screaming for him, but their voices were slowly fading.

Though he could not clearly see through all the flying debris and objects that spun around him, he could tell that his surroundings were changing - he was being sent into another dimension.

"Leo! Raph! Donnie! Sensei! Help! HELP ME!" he pleaded as he was flung around inside the tornado, tears running down his face.

The last thing he saw was a large metal barrel rushing towards him before it struck his head and everything faded into darkness.
