There are some inaccuracies in this but please do remember that this is inspired and I don't own any of the brands in this chapter nor am I claiming to.

Please keep in mind this is my first fic and that I am under 15 and that this fic is internally Leo centric so you might get some POVs of the other turtles but this is Leo angst.

I hope you like it 3

(Spin off of Bayvers, but you can think of this as any version :) btw Leo is 1 year older then Raph and Raph is the same age as Donnie and Mikey is one year younger than Donnie ) please enjoy!

5 AM:

Leo stepped out of his room, thinking this was gonna be a regular day in his life.

Why did he have to be right? He stepped into the kitchen, grabbed an apple, sat down on the couch and enjoyed a few minutes on his own scrolling through TikTok just letting time slip past, his mind went numb as he stared endlessly at his FYP full of cats.

God he loved cats.

Looking up from this one cat that learned to communicate by pressing buttons,

6AM:

He realized how much time had passed and that his brothers would probably wake up soon. He wanted to have at least another 20 minutes to himself before the chaos that was his life would unravel. His brothers weren't that bad they were just very chaotic and loud, Leo just needed a minute before all that started all over again, as it has every day for the past 13 years. Leo's phone buzzed as he was leaving the lair,

Calendar: Happy birthday! 💙

14. Everyday for the past 14 years has been the same boring routine since forever and will continue for another forever.

Leo put his headphones on his head where his ears would've been, and popped a cassette tape into its box. Splinter never let them use their phone outside of the lair unless they were texting or calling each other, a bit too paranoid that they could get tracked and kidnapped. Like what are the odds of that happening?

A bit too high.

Leo lifted the metal sewer hole cover to the side and climbed through, being careful enough to put it back on without too much trouble. Climbing the fire escape up to the roof, one of his favorite songs that took a bit too long to track down in cassette form,

He listened to the song, walking along the edge of buildings without a care in the world.

The orange street lamps and the red car lights illuminating the streets.

He'd gotten a fair amount of distance between him and the lair, doing cartwheels every few feet and walking on his hands while balancing on the edges.

'God he loved this song' Leo thought to himself, nothing like an idiot like him listening to American Idiot on a cassette tape while he literally cartwheels away from his responsibilities.

Something came whistling towards him, impaling the ground was a blowdart looking syringe inches away from his foot, Leo barely noticed it, but of course you can't go 13 years (starting today) of ninja training literally being pushed to be the best and not notice every little detail. Leo hated that skill.

He started running a little faster, being careful not to make it seem like he noticed his pursuers. Leo ended up taking a lot of random turns he didn't plan on when he left, but even after what felt like hours of random turns and jumps, with the occasional cartwheel, he finally thought his pursuers had left.

In the distance, over the buildings, crept a bit of sunlight. Leo shielded his eyes from the blinding light.

'Daybreak already? God he was so grounded'

He made another random turn just to be sure his pursuer was gone, but instead he was greeted with a boot kicking his shin, Leonardo was then tackled by three masked adults who seemed to be in their late 20s early 30s.

Leo's arms stung from the unexpected fall onto the concrete that was the roof-top, his skin peeling and he could feel the blood starting to dribble from the small but many scrapes that littered his forearms and knees.

Two of the three adults grabbed his arms and lifted him to his bleeding knees, small pools of blood starting to form from where he uncomfortably sat, the third adult harshly grabbed his shoulder and put the sharp side of a dagger to the other side of Leo's neck.

Panic began to replace the adrenalin in Leo's veins as an average height girl stood in front of him. Leo had to crane his neck to be able to look at her from his perspective.

She had asian features and a slim figure, short black hair with multi colored strands underneath and on her fringe, she had an ungodly amount of mascara on and brown eyes. Her black ninja uniform with red hem and sleeves that went down to her wrists seemed to make her pale flawless complexion glow.

'I need to know her skin care routine' Leo decided.

Leo then realized they were all wearing the same uniforms, except she was wearing

Air Jordan one retro highs (university blue) with white Nike socks and she had many multicolored beaded handmade bracelets,some rings and definitely some piercings hidden by her short hair.

All of this told him that she was a teenager.

(Nothing against teenage girls)

'She's pretty' Leo thought, though he preferred men that doesn't mean he can't think a girl's pretty.

She began to talk, one hand on her hip and making gestures with the other one, her gloves that had the finger part of them cut off. Her garnet lipstick covered lips started moving faster than he could think, music still blasting in his headphone he tried to get her attention.

"Excuse me, but-" Leo was abruptly cut off by one of the men (he thinks, the uniforms don't leave much to the imagination) holding a knife to his neck, he could see his jaw moving and his mask also, that meant he was talking. He thinks.

He obviously told him to shut up because the girl continued talking, Leo must've had a confused look on his face since the girl suddenly looked puzzled. She then said something to one of the men holding him, Leo felt the man shrug and shake his head before she looked back at him.

She must've realized he couldn't hear her since she walked up to him crouched down to his level = and took off his headphones.

"There, now you can hear me." Her voice was smooth, like butter but also sweet. It made Leo feel safe. But considering three people who he assumes are with her, feeling safe probably wasn't a good thing.

She tilted her head, "You can hear me right?"

"Y-yeah, I've just never-"

"Never talked to a girl before?" The girl was now standing back where she was earlier but now with her arms crossed.

"I've never talked to a HUMAN before, anthesis on humans." The girl chuckled when he said this.

"So, as I was saying. As cool as you look, I've been sent on a mission to capture someone that I deem would survive the mission"

She had put both her hands together and changed her posture as she explained. "You're going to be brought back to my father, then to the head scientist, then to a room where you're going to be pushed into a ball of light and we'll see from there, sound good? Good. Now-"

"Erm- Miss Karai?" The Ninja to Leo's left asked, his voice wavering as he held up a finger to ask a question.

'So her name was Karai? That's actually a nice name'

She had turned 90 degrees as if she was going to start walking back to wherever her home was, when she got interrupted by one of the men still holding him down.

"What do you want George?" She sounded mad

The Ninja, who's name was George, made a baffled noise as if he wanted to gasp but was too shocked to do it.

"My apologies, but don't you think telling the thing our plan is going to ruin things if he gets away? Let alone now he knows my name-"

Leo hadn't even seen Karai move, he's never seen anyone move so fast. Karai had gone from a foot or two away from him to not even two inches away from. He heard a sickening crunch before realizing what had happened.

He felt the ninja who was talking a few seconds ago was now on the floor clutching his face.

'Did Karai just freaking sock George in the nose?!'

Karai was now crouched in front of him

"Where are my manners, my name is Karai. What's your name?"

Leo was taken aback, this girl had just punched one of the guys that was holding him down and even though he could've probably overpowered the two men, he was most probably gonna lose his shit against Karai.

"My name? Oh, its Leonardo, but you can call me Leo"

Karai made an acknowledging hum and nodded her head slowly.

"And if you don't mind me asking, Leo. How old are you?"

Leo gulped nervously, this girl could probably kill him if she wanted to and turn him into turtle soup seasoned with mutagen.

"I just turned 14, today. It's my birthday" Karai's eyes widened with shock, but she quickly corrected it by giving him a sympathetic smile.

"Happy birthday, Lee. I'm sorry but i have to take you to my Dad now"

It was Leo's turn to be shocked,

'Her Dad? But she said if i go to her dad then i'll have to the head scientist and then I- well I don't really want to find out what the glowing ball of light was'

"Can't you just let me go? Please? I'm not even a legal adult yet, I don't really want to get pushed into a ball of light!" Panic seeped into his voice.

"I'm so sorry Lee. But if I let you go and one of these bastards told on me then It's game over for both of us."

Karai glared at the Ninja on the floor still clutching his face now sobbing quietly, she rolled her eyes and diverted her attention back to Leo.

"For both of us?" Leo asked shackley.

"Yep, but if you come with me without a fight then i'll make sure you get hot meals and a warm bed and whatever- uh… Turtles need, like a lamp or a brush or something. And i can bring you posters and comic books and more, uh-" She looked down at the cassette player that had stopped playing automatically "-cassette tapes, and we can have sleep-overs and make stuff and celebrate your birthday" Karai looked so genuine and seemed actually nice "Do you have a family Leo?"

Leo realized it was morning, his dad and siblings must be worried. Or not…

Raph had told Leo the other day that he hated him, Mikey had lost his favorite comic book and refused to apologize and Donnie (tho Leo would never admit out loud he felt closer too then the others) had refused to talk to Leo for the past week because he was too busy fixing Raph's phone.

Not to mention they'd forgotten his birthday for the past 3 years, 4 if you count today.

And Master Splinter was okay, even though it seemed like he made Leo take care of his siblings in his place.

"I do" Leo reluctantly answered "I don't think they like me very much tho" He hung his head, feeling tears well up threatening to fall.

Karai put a hand on his shoulder "It's ok, you're ok" the hand moved up to Leo's cheek, urging him to look up and meet her eyes, Deep blue eyes met Dark brown.

"How about when we get back, I show you to your room and then we decorate and watch YouTube, or Netflix, I don't know if we have Disney-plus though it'd be weird if we don't" She looked at the the guy to Leo's right and he shrugged, clearly not knowing if they had the subscription to the channel or not.

"That actually sounds really nice" Karai lit up at Leo's statement "My Dad told me not to believe strangers if they tried to get me to go back to their house, but I really don't want to go back home. So I-I'll go.." Leo said, barely above a whisper.

"I promise you, you will not regret this Lee! You're gonna love this!" She said with a big bright smile that somehow seemed genuine. She gave a stern glare to the remaining two Ninja, they seemed to get the message and let Leo go.

Leo caught himself with his hands before face planting into the concrete, Karai also helped support him. She grabbed his hand and hulled him to his feet, only then did he realize how short he was. Karai was like 5'6 or 5'7 but Leo (last time he checked) .

Was 5 '1, never before has Leo been glad he wasn't Mikey (he's 4' 10).

Karai made a hand gesture to the other Ninjas and they picked up the, still crying, comrade and slung his arms over their shoulders.

Karai put her arm around Leo's shoulders as they walked slowly towards a huge black brick house with a big circular window at the front that, from what Leo could make out, had a deep red curtain on the inside. It also had big dark wood Victorian style doors, and glass roof with beautiful derails.

"So Leo, when we get to my place how do you feel about becoming a Ninja?"

Author's note: I hope you liked this first chapter, I will be posting more soon! And yes we are getting some good big sister Karai moments! BTW: I only picked Bayvers bc I like the sibling relationship the turtles have (I don't condone T-sest nor do I support it) and i also like how detailed the turtles are but there are a lot of things that aren't addressed in the movies so i think there should be more fanfiction. But if you don't like Bayvers that's totally cool! You can Imagine the turtles being from any universe, I'm not exactly sticking to the og movie script by adding my own details. I hope you liked it! Also my brain can't think of a realistic face for the life of me so this whole time I've been picturing the turtles in 2012 or 2018 even the 2023 movie that just came out's art styles! So if you find any inaccuracies related to their designes then it's probably because of that. I hope you liked it! :)
