#bayverse splinter

So today I thought long and hard, and found what I loved about Splinter. Here (along with my drawings) are my conclusions.

He is a listening ear, and a source of gentle support when he witnesses his sons struggling, even (especially) with obstacles they must ultimately face alone.

He learns and appreciates the intricacies of each of his boys’ personalities, and believes undoubtedly that they can succeed in whatever they put their mind to.

He finds ways to share in his sons’ joys, finding his own way to relate to them, and in turn they want to make him proud with what they achieve.

He acts fearless, even when he doesn’t feel it. His character, at the end of the day, is there to protect his sons, and do his best to teach them how to protect themselves one day.

Happy Father’s Day, to all those who celebrate.

Something happens.

The lair is attacked and, in the midst of the fight, Splinter is taken. Badly hurt, he still manages to escape his captors and wanders the city, calling out for his sons in his delirium before collapsing.

Which is how you found him.

Walking home one night, you heard something above the music in your earbuds...a weak, frightened voice of an old man, calling out for "his sons." Something crashes in an alleyway and you follow the sound.

Admittedly, seeing a giant rat was shocking.

But this is NYC and giant rats aren't too shocking, are they? Just another day in the city, TBH. And he's so scared and so hurt, mumbling names softly...and you can't turn your back on him. Luckily, you don't live too far and you're able to help him into your apartment.

There's no calling the cops or an ambulance, obviously, but luckily you have enough first aid knowledge to help him. It takes a few days of taking care of him until the rat wakes up completely, confused and worried as he tries to get up.

"Don't," you tell him softly as you come into the room. "Don't move too quickly, you'll hurt yourself."

"Where am I? Who...who are you?"

"I'm Y/N."

And that's how you before Splinter, as learn his name, taking care of him a little longer. He likes tea and soap operas and reminds you of your grandfather with his wisdom and wry sense of humor. It isn't long until he's gathered himself enough to figure out a way to contact his sons, the one's he told you about.

Leonardo, Michelangelo, Donatello, and Raphael.

They're exactly as he described them, Splinter smiling as soon as he heard movement on the rooftop, four absolutely giant turtles clambering in through the balcony window.

"Father!"

They're all around him at once, worried and trying not to cry (but definitely crying a little), Splinter comforting his boys and crying a little bit too.

And that was how you got tangled up in thier lives, befriending the father before befriending the sons.

◇ Little Things ◇

◇ You and Splinter like a lot of the same shows. Sometimes you watch together (particularly if it's a season finale or holiday special or something) but typically, you watch separately at your homes and then talk about it on the phone.

"I can't believe she tried to seduce Raul!"

"I can," Splinter scoffs.

◇ You have tea time together as well, and talk about everything going on in your lives. Even though you think your life is boring compared to his, Splinter disagrees. He's very interested in the typical life of a human, it seems so different from his.

◇ He will insist on you learning at least some basic self defense, especially in this city.

◇ When he realizes that one of his sons has developed feelings for you, Splinter is rooting for ot to happen so you can be his daughter-in-law.

can I request the Bayverse! Boys if they were to have a baby? Maybe splinters reaction to having a grandchild? don’t forget to drink and take breaks!

Hii anon!! Hope you’re doing good aswell! I have a few requests in my inbox on this topic. Some said if the reader is pregnant, one if the reader is in labor, and the majority if they had a newborn. So, I’m just going to use yours and post it here. Sorry for not posting in a while, I’m now bouncing back 🫶🏼

Bay! Turtles if they had a newborn baby.

Comfortably, you and your partner return home with your baby. Going to your home, it was time for his dad to see his grandchild. What would be Splinter's reaction!?

Zero warnings here.

Just some family fluff💕 Bay turtles

Implied that the turtles are in a relationship (separate!).

Leo

He brought her straight to your shared bedroom, where you were resting under a heavy pile of blankets. Looking up, exhausted but smiling, you watched him position himself at the entrance of the room like a sentinel. The moment the baby let out a tiny, soft whimper, Leo’s rigid posture shattered. He immediately unbuckled her, pulling her flesh against his chest and humming a low, rumbling frequency that vibrated through his shell. You softly let out a breath, your heart swelling as you watched his massive frame instantly soften to soothe your daughter back to sleep.

He remained standing right beside your bedside, frozen in his protective vigil, until a slow, deliberate step broke the silence. Splinter entered the quiet room, his long robes sweeping the floor. Leonardo stood up taller, holding his newborn daughter with a rigid posture born of nervousness, though he cast a quick, reassuring glance down at you first. He was starting to calm down.

"Sensei," Leo whispered, his voice cracking slightly. "Meet your granddaughter."

Splinter approached the bed and looked down at the tiny girl. He did not immediately reach out. Instead, he placed a warm, furry hand over Leo’s massive, trembling knuckles while reaching out his other hand to gently rest over yours on the mattress, tethering your new little family together. He closed his eyes and inhaled deeply, sensing the fierce, protective aura vibrating off his eldest son and the quiet warmth coming from you.

"You hold her as you hold your katana blades, Leonardo, with honor and absolute defense," Splinter murmured, opening his dark eyes, which shone with immense pride. "But look closely. She is safe. Relax your shoulders. You are no longer just a leader to your brothers; you are leading your own family."

With a gentle nudge, Splinter guided Leo's arms into a softer cradle. You leaned up slightly against your pillows, offering Leo an encouraging nod as he finally let his shoulders drop. Splinter then extended a single clawed finger, touching the baby’s tiny, smooth shell. The infant let out a soft sigh, and Splinter bowed his head, a single tear disappearing into his gray whiskers.

"The line is unbroken," the old master whispered, looking between you and his son with a soft smile. "She will be strong, because she is yours."

"She has her father's heart, Splinter," you said softly, your voice thick with emotion as you squeezed the old rat man’s hand. You looked up at Leo, whose eyes were bright with unshed tears. "And with you and Leo guiding her, she’ll never have to doubt how safe she is. She's going to be so loved."

Leo swallowed hard, his gaze shifting from the baby to you, a brilliant, breathless smile finally breaking through his tense expression. "We'll make sure of it," he murmured.

Raph

Raph spent the hours before your arrival pacing, snapping at his brothers to stay quiet, but the moment you both finally walked through the door, he froze. The sheer size difference between the massive brawler and the tiny bundle was overwhelming. He stood back, crossing his arms and pretending to look tough, but his eyes were wide and completely glued to his newborn son.

He followed you straight back to his room, pacing like a caged beast. You settled onto the edge of the mattress, exhausted but watching him with a soft smile. He held the baby boy tightly against his massive chest armor, his face twisted into a fierce scowl of pure, protective anxiety.

When you reached out and gently asked him to relax, he panicked, backing up against a brick wall. "He won't stop crying," Raph growled softly, his voice thick with frustration and exhaustion as he looked down at you. "I'm tryin', but my hands are too big. I'm gonna break him."

Before you could stand to help him, a slow, familiar step echoed at the doorway. Splinter entered the quiet room, his long robes sweeping the floor. Raph looked up at his father defensively, as if expecting a lecture.

Splinter let out a soft, rumbling chuckle that instantly cut through the tension. He stepped close, forcing Raph to stop pacing. Splinter reached up, his small hands gently lifting the tiny, squirming baby boy away from Raph's spiked armor, while extending his other hand to rest warmly over yours, bringing you both into the moment.

"A father’s strength is not measured by the force of his fist, Raphael, but by the gentleness of his touch," Splinter said softly.

He cradled the infant close to his chest, humming a low, ancient melody. You leaned forward, watching as the baby’s cries dwindled into soft whimpers, finally falling fast asleep against the old master’s robes.

Splinter looked up at his second son, whose tough exterior had completely melted into watery-eyed awe, and then gave you a knowing, affectionate smile. With absolute care, Splinter placed the sleeping baby back into Raph’s massive arms, while you guided his leather-wrapped forearms into a proper cradle shape.

As the tiny weight settled onto his biceps, Raph froze entirely, terrified to breathe. But as you leaned against his shoulder to reassure him, a soft, involuntary purr rumbles in his throat—a sound the brothers hadn't heard since he was a tot.

Splinter smiled deeply at the sound, patting Raph's massive shoulder. "See? He knows your heart is soft, my son. Do not fear your own strength. It is the very shield he needs."

"We'll protect him together, Raph," you whispered softly, squeezing his arm. Raph looked between you and his sleeping boy, his fierce scowl completely replaced by a tender, breathless grin.

Donnie

You and Donnie went to the hidden garage entrance, wearing a pristine, white lab coat over his gear. He immediately ran a handheld air-quality sensor over the baby carrier to ensure the sewer air filtration system he built was working perfectly before guiding you inside.

Instead of going to the usual living spaces, he led you straight into his lab, directing you to a newly constructed, soundproofed corner that he had meticulously transformed into a sterile, cozy nursery. You settled into a comfortable chair he had set up for you, exhausted but amazed by his dedication.

Donnie was frantically adjusting a custom tablet, analyzing data strings of his newborn’s vitals while the baby slept peacefully in a high-tech bassinet. He presented you with the screen, eagerly pointing out the automated tracking charts. While he was explaining the exact decibel levels of his custom white-noise machine, the baby stirred. She reached out from her blankets and wrapped her tiny fingers right around his tech-glove wire. Very loosely, but her father in awe.

Donnie stopped talking mid-sentence. His jaw dropped as he stared down at his hand, completely abandoning his lecture to just admire his child.

In the lab, the rhythmic chiming of medical monitors filled the air as Donnie quickly snapped back into panic mode, staring at the flashing lights. Splinter stepped up behind his third son, placing a firm hand on his shoulder while casting a warm, welcoming look toward you.

"Donatello, please turn off the screens."

"But Splinter, the oxygen saturation levels fluctuated by 0.2 percent and—" Donnie started, his glasses slipping down his snout in his panic.

Splinter gently but firmly took the tablet from Donnie’s hands and set it face down on the desk. He then walked over to the bassinet, carefully lifted your baby girl, and walked back to where Donnie sat right beside you. Splinter placed the warm bundle directly into Donnie’s lap, while reaching down to gently pat your hand, anchoring the two of you together.

"Look at her, Donatello. Not at the numbers," Splinter instructed softly.

Donnie froze, staring down at the tiny, breathing miracle in his arms. As if hearing her father's voice, the baby opened her eyes, looking up at him with intelligent, dark eyes. Splinter smiled, leaning over his son's shoulder.

"Science can explain how she breathes, but it cannot explain the magic of her existence. You cannot calculate love, my son. Put down the data, and simply be her father."

Donnie’s shoulders finally dropped. He let out a long, shaky breath, letting the data slide completely out of his mind. You leaned your head against his shoulder, watching as he finally relaxed and leaned down to press his snout against his daughter’s forehead.

"She's perfect, Donnie," you whispered softly, reaching over to rest your hand over his. "No bugs, no errors. Just perfect."

Donnie swallowed the lump in his throat, keeping his eyes glued to her face. "Yeah," he murmured, his voice thick with awe. "The coding on this one is absolutely flawless.

Mikey

After you and Mikey cleaned up the baby and prepared yourselves to introduce him to the family, the homecoming became an exercise in suppressed excitement. Mikey had to be physically restrained by his brothers from throwing a full welcome party with banners and confetti. He settled for a handmade, brightly colored "Welcome Home" sign taped to the turnstiles instead.

The moment you both walked through the door, he tiptoed up to you on his knees, his eyes sparkling with unshed tears as he peeked under the blanket. The moment the baby opened his eyes, Mikey let out a gasp, high-pitched whisper of, “look, he has your eyes." He immediately offered his pinky finger for the baby to hold, gently swaying side-to-side and whispering a list of all the comic books and video games they were going to play together when he grew up.

He practically floated as he led you back to his room, which was cozy and filled with the sounds of a cartoon playing on low volume. You sank into a pile of oversized floor pillows to rest your tired body, smiling as Mikey immediately got down on the carpet. Surrounded by plush toys, he eagerly showed a colorful comic book to his newborn son, who had drifted back to sleep.

"Dad look at him!" Mikey beamed as Splinter slipped inside the room, a warm smile instantly gracing the old master's face. Mikey carefully scooped up the baby and held him up like a proud trophy for his father to see. "He’s got my smile, right? And look at his little webbed toes. We're gonna build the ultimate blanket fort later."

Splinter knelt down on the floor beside his youngest son and you, an old bone popping as he did so. He reached out to lift the baby into his arms, letting the little boy rest against his gray fur while using his free hand to gently pat your knee, pulling you close into the circle.

The baby instantly twitched in Splinter's arms, his tiny hand reaching up to grab a lock of the old rat's beard. Splinter let out a joyful, raspy laugh, his eyes crinkling with pure delight.

"He possesses your light, Michelangelo. For many years, your joy has kept this family alive in the darkest of places. Now, you have a new light to nurture."

Splinter leaned forward, pressing his forehead against the baby’s, then looked up at Mikey and you with profound tenderness. "Never let the world take away your playfulness. It is the greatest gift you will give to him."

"We won't, Master Splinter," you said softly, leaning into Mikey's side and wrapping your arm around his shoulders. "Between the two of them, I think our home is always going to be full of laughter."

Splinter smiled deeply, carefully passing the sleeping bundle back into Mikey's arms. Mikey held his son close to his chest, the usual hyperactive energy melting into a soft, glowing warmth as he looked from the baby up to you.

"Always," Mikey whispered, his voice quiet and thick with emotion. "We're gonna be the happiest family ever."

Hii guys, I hope you're all doing amazing! I tried hard with this one. I’m not a mom, but I have younger siblings, so I tried my best to capture them if they had a newborn. Reading other people’s headcanons helped me a lot. I would rather melt my brain to get this done than use AI slop. (FYI we don’t use/support ai in this blog just so we are clear). Anyways, I also think that Leo is a girl dad, but I think that’s another head canon for another post 😁 take care everyone, stay safe 💕

Honestly I think he’s one of the best versions of Splinter. He has 2012’s protectiveness and skill, and he also has 2003’s caring nature. He’s a REALLY good dad in both movies and it shows- he’s patient but firm with Raph, understanding with Mikey and Donnie, and very guiding with Leo in the 2nd movie. The parts where they actually called him “Dad” were really sweet.

My one complaint about him is part of his origin. It was really cool seeing the Turtles be lab experiments at first, (since, as you all can guess, I love experiment AUs and OCs) and I liked that part a lot, but with the part of how he learned Ninjstu it just felt really disappointing. Same with MM Splinter, having him know/learn Ninjstu from a book or movies he found in the sewers just feels really out-of-character for him. Not to mention, Ninjstu is an actual HUGE part of Japanese culture and traditions, so honestly having it learned from mainstream, popcorn flicks than actual genuine culture like 2012 Splinter just feels kinda iffy. (I really don’t wanna call it cultural appropriation and blow it out of proportion, but in some ways it feels like that a little.)

Okay. These guys live in a sewer. All versions of them. I thought of this after watching those funny fart spray prank videos. They've smelled the worst of the worst for years. From soggy, moldy diapers to your ex boyfriend's cheap and nasty cologne that you threw out onto the street. To Mikey's gassy moment that one night they returned to the lair🤣🤣🤣. I think ya'll know where this is about to go.

Leonardo

Having a human girlfriend was never on his list

That includes one who enjoys pranks like his little brother

He was meditating in his room when you peaked in to check on him

This was the perfect opportunity to mess with him

His eyes were closed, silent, in the zone

Though he sensed you, he did not sense what you were about to do

You pulled out the spray, press 2 times and left him alone

When the smell hit him, he scrunched his nose, his body goes rigid

His brain short circuits, for 3 seconds he doesn't move

He starts to struggle keeping his posture, then the smell intensifies

He gets up, leaves his room and starts looking around for the one responsible for planting stink bombs in his room

He found you in a corner, snickering with the spray in your hands

'Busted!'

"You didn't" Long pause,"That's a war crime in twelve countries!"

That was his way of saying what you did was an act of betrayal and a gut punch to his honor

The face he was making would've saturated your underwear but he was not "down to clown" after what you did

His snout wrinkled involuntarily but calmly asked you to hand over the spray

"Consider toilet cleaning duty for an entire week, your punishment. I'll give this to Donnie to put in an undisclosed place so you Do Not get anymore ideas."

At that point, you got your giggles out and took your punishment like a boss

After a week of cleaning up the toilet and being forced to smell their crap, he forgave you

He won't admit it, but he was impressed by your stealth in a way

He cuddled you after patrol, whispering in your ear

"Be grateful I wasn't in one of those blow up suits. Otherwise, you'd be doing more than cleaning toilets. You'd be cleaning Raph and Mikey's room." He chuckled

You gagged at that

Raphael

You're either rotten to the core or quite a risk taker to pull any pranks with this deadly teddy bear

He was a tricky one because Mikey's been taunting him a lot lately so you had to be creative

Hes been at it in the gym and fixing his bike, so hes been on an adrenaline high

He needed to take a break and you needed some nookie

It was easy working the moves on him since he was a frickin' dog every time you shook that naturally formed donk

After an hour of rough whoopie, he fell asleep

You went into action digging through your shorts, took out the spray and did a few spritz

You got up, left the room and waited for him to awaken

It did not take long at all as he jolted up out of bed, stark naked and started flipping his script

If he was lifting his weights mid rep, that floor would be destroyed because he would drop it in an instant

He started hollaring,"WHAT DA ACTUAL CRAP!!!!*coughing* THAT"S DISGUSTING!!!"

He would violently gag, cough and wheeze at the smell, even his eyes watered

You started to feel like crap because he actually threw up

'Maybe I sprayed too much. Note to self, only do 1 spritz. Not 5!' How were you supposed to know how strong this stuff is?

He'd see you peaking in on him, taking the hint

"YOU! YA LITTLE SNEAK! YOU DID DIS!!!??? WHAT WOMAN SMELLS LIKE DAT!!?? COME ERE!!!!!"

He was so annoyed, he burst out of his room in his birthday suit chasing you around the lair with the intent on spanking you

You dropped the spray, Raph sees and wonders whose dumb idea was it to make a fart spray and for how much

The chase came to a halt when you crawled into a tunnel he couldn't fit in

He gave you a warning,"Ya got me now! But best believe I'm gettin' ya back with the real thing!"

Hes standing there yelling at a tunnel then turns around to see Master Splinter behind him

"Have you not outgrown the naked party faze, Raphael?"

Raph looks down, embarrassed, covers himself and gets back to his room

Time flies, he contacts you

"Please don't still be mad at me. I'm really sorry. It was just a joke. I hope you're feeling better."

To your amazement, he reacted differently

"Nah, I ain't mad at ya. Ya outdid Mikey dats fer sure. But, Imma still get ya back, my lil stink pot"

His cackles made you shiver

'He can't smell any worse than that spray! Can he?'

Donatello

Hes been working on and cleaning the truck

Getting fed up with Mikey using it as his private sex room

You came along with the intent on making him feel better

He politely suggested you relax in his room until he is finished

That didn't last long as you started plotting

Unbeknownst to him, you planted little fart devices around the truck

You learned a thing or 2 from watching Donnie and you were determined to get him

You kept watch as he circled the truck, then he stopped in the area where one of the devices was planted

With a Cheshire grin, you pressed a button, and unleashed a cloud of pure stank

He was unfazed at first because he lives in a sewer so hes used to fowl smells, then you took it up a notch and pressed it again to set off the other devices

However, as soon as he inhales, the sneeze fest started

"Achoo. What the.....that has to be the most foul scent I ever had to deal with!"

He starts gagging a little, looking directly at the device that sprayed him

He starts analyzing, using his handheld scanner to identify the chemical composition and study the device

Hes more fascinated and amused than disgusted or upset

You came out of the corner as hes wiping his eyes from the fumes, not emotions

"What do you think of my device? I've invented it so that it can be controlled by remote control, diffusing any substance you so choose. You've also been pranked, My Love." You smirk at him

After looking over the device, he finally spoke

"Marvelous!" He compliments,"Not the pranking part, but very lethal the substance you placed in the device, but an amazing form of technology that could be beneficial during certain missions. Well Done, Love. Well Done."

He has dismissed the fact that hes been pranked, wanting to know more about how you designed the device

You and him talk for a while, however your prank had a con to it

Not only did it spread in his garage, it spread throughout the lair!!

Everyone who was present came to the garage demanding to know what Donnie did

After explaining what happened, Splinter scolded you good

Donnie gave his own little reminder,"My advice to you, My Sweet. Is to sleep with one eye open tonight."

He was either gonna create something more lethal or shut off your electricity and Wi-Fi to your place

Michelangelo

He is the Prank Master

He may even be more tricky than Raph since hes the clown of the group

You and him were in a prank off for the week

The others wanted no part of it so you were pranking each other throughout the lair

It started small with shaken sodas to whoopie cushions

Medium: hand buzzers to switching sugar to salt

Large: filling bedroom with rubber ducks to covering his room with glitter

He was ahead of you so you had to up the ante

Spending $15.99 on a fart spray is not your best choice but you had to get the upper hand against your turtle lover

He was eating his pizza in peace, reading his comics when you acted

You carefully sprayed once a few inches away from him and waited

To your shock, he didn't react right away, so you sprayed some more

He swallowed his pizza, took in a big breath and gagged

"Oh my.....Dang! That's dangerous! Smells like Raph and Leo after fighting for a week straight in the junkyard with skunks as their audience!"

He was hype, being goofy, being more dramatic then those women from those stupid reality shows

"Aww. If this is what Ed's room (from Ed, Edd, N Eddy) smells like? Not even Raph's farts smell like that!! Whoooo Weeee!"

He was even laughing through it, sneezing a little

Dude is used to so much it's not even funny

Finally you came clean,"Gotcha. Hope you enjoyed the new 'air freshener,' Baby. HAHAHAHA!" You tossed the fart spray at him

He laughed with you, then he brought you into a tight hug

"Ya got me, Babe." He surrendered,"You are The Prank Master of the Lair! Congratulations!"

You and him share a kiss, his brothers standing off in the distance wondering what kind of kink you and Mikey are into these days

Bonus: Splinter's Reaction

Just like ya mama smelt your crap since you were young

He had to put up with and smell the turtle's crap

So for you to bring that fart spray into the lair and spray it, is ridiculous

He'll take one whiff and assume it was Mikey

When he finds out it was you pulling a prank, he'll let out a deep sigh

He will call those turtles and you into his quarters, laying it on them as calm as he possibly can despite the distasteful odor

"I did not survive the Foot and The Shredder's attack to die of olfactory assault in my own home." He scolded,"There will be extra meditation. All Of You."

You will do as your told, unless you want your behind whipped too by that dangerous tail of his

He will shuffle away to his bonsai garden, muttering about 'the youth of today.
