(A/N): Hello~! ^^ I just have a couple of adminny things to get out of the way before I let you go.

First: I've already posted this story on my quotev account, where I am 'Ed and Al and TurnTups'. I confirm this is my own work. uvu

SO - This is set in the Season 2 of the 2012 TMNT series, somewhere between episode 12 and episode 16.
ALSO - This is very very alternate universe, guys. I know that Retro-mutagen wouldn't do this (actually it's closer to normal mutagen at this point) and especially not make the boys so shiny and shojo but AU. A. U.
With that out of the way, I'll see you at the bottom!

Chapter One: Accidents Happen

April O'Neil used her elbow to turn the handle of her Aunt's front door. Her hands were occupied with her school bag, which would not stop sliding down, and a large sized latte. School was as it always was, but it had its effect in tiring her out a little more every day.

All she really wanted to do was sneak off into the sewers and hang with her best friends. It wasn't a gang meeting or anything, don't get it wrong, her four best friends just happened to be giant, half human turtles. It's a long story.

However, with her midterms around the corner, April was looking forward to a night of assorted revision and studying. Not to mention she had to tidy her room, make dinner for her and her Aunt, whom was out tonight, and continue research on finding her dad. Hence, the large latte.

As soon as she stepped into her apartment, she could tell that something was wrong. She hadn't thought it possible to be messier than she had left it, but it was. Not to mention the various fast food boxes strewn everywhere. Her bedroom door was also slightly open and she knew that she had closed it that morning. Her aunt hadn't left that far behind her.

Quietly, April clicked the door shut with her back, placing her bag down gingerly next to her. With one thumb, she popped the plastic lid off of her coffee cup, whilst her other hand closed around a large, black umbrella.

Using all of her konoichi training thus far, April padded across the apartment, tightening her grip on the umbrella handle. As she did so, she heard voices coming from her room. It didn't sound like Dogpound or Fishface, so that was a bonus, but it could still have been Foot clan soldiers. They were talking in hushed voices that made her feel anxious.

She paused again when she was stood next to the door, taking a breath to steady herself.

With a yell, mainly to reassure herself, she spun and kicked open her door, throwing the unlidded coffee as soon as she saw the four trespassers. It hit the first square in the face and she swung her bat, colliding with the side of another's face. Her blood was roaring in her ears, but she thought she heard her name being called. The boys were wearing black, so she assumed it was just Kraang Foot clan confirming her identity.

Ducking under a punch, she pulled out her tessen and caught the third boy on the back of his neck. Needless to say, all three went down like a sack of bricks in only a few seconds.

Once again, her name was called as she faced off against the last boy, who was taller than all the rest. An upgrade?

"April - I'm Donatello!" the boy cried, his hands shielding his face.

The name made April hesitate and glance around. Donnie's bo staff was slung on his back. The boy's leg was raised in the way that Donatello did when he was scared. Heck, he even had the small gap in his front teeth...but that was impossible.

"Nice try-Donnie's a turtle." April snapped, raising the umbrella and opening her tessen. She was about to send him tumbling to the ground with the rest of his brothers...then realized they weren't all on the ground anymore.

In fact...one was right behind her, with her in a headlock.

"And I'm Raph," the boy growled. "Now stop whacking us and listen!"

April squeaked and dropped to her knee. It unbalanced the boy and sent him tumbling into the one called Donatello. He did have Raph's sai's.

She turned to the other boys, who were picking themselves up from the floor gingerly. One had Leo's katanas strapped onto his back and the other had Mikey's nun chucks. Now that she looked closely, she realized the blonde boy had Mikey's freckles...

And that none of the four had unsheathed their weapons.

"B-b-b-but..." April stammered out, dropping the umbrella heavily on the floor to open and close her tessen. She looked again at the four boys, though harder this time. They were human. Definitely human...however they also looked uncannily like the turtles. Was this some kind of trick?

"Believe me, we were surprised as you were," the one with Leo's katanas said, gently. He raised his hands as though he was trying to settle a cat. Now that the thumping of her heart had slowed down, she realized they even sounded

like their turtle counterparts.

As much as it was crazy, her sixth sense was telling her that the ninja turtles were standing in front of her...as boys her age.

"So, how, exactly did this happen?" she took a deep breath, putting one hand on her temple.

"Are you gunna stop hitting us?" the one who'd said he was Raphael, replied, with narrowed green eyes.

April nodded, still trying to remain calm. It was just so wrong!

"Well," Donnie stepped forward, still watching the girl with wide eyes, unconvinced she was through beating them. He took a breath to say more, but the blonde one burst forward.

"You remember that group hug we had yesterday?!" he called out. Yup, April thought to herself, definitely Mikey.

"Don't tell me I did this?" she asked, aghast.

"No, no, no," Donnie said quickly. He stepped back as Raph head locked Mikey for interrupting. "This...this was all me."

There was a silence...rather, Mikey's screams echoed whilst Raph noogied him.

April sat on her bed, patting the space next to her. Donatello sat next to her sheepishly, whilst Leonardo, or she assumed it was Leonardo, leant against the doorframe. He looked as though he was keeping watch.

"I was just experimenting on some retro mutagen to turn Wing-I mean, Mr O'Neil-back into a human," Donnie explained. "But, well...Mikey," he broke off to glare at the youngest brother. "Went through my lab on a skateboard. He jogged me and the mutagen flew into the air. We all got hit with it and...well..."

"You turned human!" April gasped, her sapphire blue eyes wide.

Donatello nodded grimly. It was a believable story and the evidence for the truth was overwhelming. Mutagen transformed the subject into the last living thing that they touched. Which explained the group hug. Despite Donnie's protests, April felt somewhat responsible still.

"You were the only person we could think of to go to whilst Donnie...sorts this out." Leo cut in, he rubbed his neck at the end. Obviously they were all unsure what 'sort this out' even meant. "Aside from Casey, of course, but we don't know where he lives."

"Probably under a bridge," April muttered. Then she shook her head, Casey's living conditions weren't important. "So you broke into my house whilst I was at school?"

"We don't exactly have a key." Raph murmured.

"Thanks," the teenager snorted.

She looked at the four boys again, chewing her lip as she thought. Donnie had long hair the colour of black coffee, tied back in a messy ponytail that stopped just short of his waist. His skin was the colour of a clay pot before kilned. But his eyes were still familiar, a strange colour not quite red and not quite brown.

Raph had finally let go of Mikey and was leaning against the window. His hair had come out scraggly, shoulder length and black, though, when the sun hit it, it looked maroon instead. His skin was lighter than Donnie's, but more brown, like the colour of nuts. Whereas Mikey's hair was a brilliant bottle blonde that was curly too. His eyes were a glassy blue, that made him look like the angel he definitely wasn't. His skin was very pale, closer to the colour of milk, which just showed off his aforementioned freckles even more.

Finally, her eyes skimmed to Leo. He looked more latino than his brothers, with honey coloured skin and ink black hair. He'd even managed to put the end of it, since it went down to his chin, into a small ponytail.

All four of them were wearing stained, old clothes that, no doubt, they stolen from the sewers or nearby bins. They also still had the coloured bands they wore around their eyes.

April realized they were all looking at her expectantly too.

"You can't say here," she said incredulously. "My aunt would go nuts."

"Of course not," Mikey made a 'pffft' sound with his mouth. "I'd never leave ice cream kitty."

Everyone took a breath to ignore that last part. Mikey's 'pet' cat had been transformed by mutagen into...well, it had been helpful that one time...

"We don't have to stay here, but we do need a human guide, so to speak." Leo explained. Raph and Mikey flashed him a 'what are you talking about' look and he gave the smallest of shrugs at them.

"Right!" April caught on. "You guys don't only have to go out at night anymore!"

"Not only do we have the chance to experience the city as normal humans, but we can gather a ton of intel on Shredder and the Kraang, since they won't recognize us." Donnie said excitedly.

"You're in to help us, right?" Raph finally cut to the chase.

April's gaze flicked around them again. Four turtles who've minimum contact with people, only seen the city at night and an unhealthy pizza obsession...not to mention teenage hormones on top of all of that...

"No offence guys, but you're going to need as much help as you can get."

(A/N): Yeah, sorry another important thing that would only make sense if I put it here:
My (My = mine alone) headcanon is that the turtles aren't biologically related, more like adoptive brothers, so I made sure they weren't all just pretty copies of the same person.
My designs for the turtles can be seen on my quotev version, but feel free to use your imagination.
Thanks for giving me this chance, you know what to do if you enjoyed it. c:
