Despite being the same age, they’re not REALLY twins due to their turtle species, and both Leo and Donnie are aware of this. However, that didn’t stop Leo for still seeing them as such. He just LOVES the idea of them being twins so much. Donnie eventually just forgot about it and went along with it.
Splinter let each of the boys choose 1 specific day for each of their birthdays, since they all were different ages and none of them knew when they’re true birthdays were. This time was a special time for Leo and Donnie since they get to decide together, since they were twins.
Leo and Donnie share a favorite food besides pizza, spaghetti. In fact, it’s also their birthday food.
Leo’s favorite color after blue is white & gold, while Donnie’s after purple is black.
Even though it’s still very obvious that they love and care for each other deeply, they used to be a lot more close when they were little.
A common misconception is that Donnie is “the evil twin”, when it’s really Leo.
Leo actually tried to pull off the eyebrow thing like Donnie. It didn’t work out.
Reader Addicted To Caffeine/Insomniac (Rise & Mayhem)
Nonspecified romantic or platonic
Leo
Stays up with you
Insomniac has gotta get something to do or he’s gonna go crazy
Knows you should go to sleep, but only really brings it up when it’s been five days or more, he’s wayyy to exited to hang out
“Ooohkayyy, y’know, why don’t we go upstairs and go to sleep? Hm? That sounds like a great idea.”
“You can if you want. I’ll stay up, it’s only been- what, a day? Two?”
“Five.”
“That explains my seven fingers.”
He portal’d you to bed, plain cheating if you ask me
Raph
Oh absolutely not
*sees you with your fifth energy drink that day*
“No.”
“But-“
“N. O.”
He just wants you to be healthy
Gives you different ways to get energy
“You tried exercise? Or… sleep?”
*hissing noises*
“Please.”
Donnie
Same tbh
Lab work does that to you
When you are Donatello, at least.
Can’t sleep? He doesn’t care why or so he would like you to believe, he just provides less than silent company
You’re not getting out of his ramblings.
Ever.
“And Pythagoras once said that-“
Mikey
Tiny bit concerned
At least you’re up, he can take you on late night adventures now!
“Wow! The neon signs in this street light up your extraordinarily deep eye bags wonderfully!”
“…I-“
“Real artistic inspiration!”
“Okay-“
Leo
C o n c e r n
“Hey I don’t think this is that healthy? Like I mean, I could be wrong and all but.”
*quietly opens another can*
“Okay- yeah- no- hand it over.”
Raph
Thinks it’s cool
Genuinely he does
Until you’re NOT getting enough sleep, then he’s going to actually tackle you into bed
“NO, WE ARE GOING TO SLEEP. I WILL KNOCK YOU OUT.”
Donnie
He’s up watching k-pop music videos let’s be 100% here
Now, he has a buddy to do that with!
Not until he realises how much caffeine you’re consuming on average
“Well that’s definitely unhealthy. Do NOT give me that look.”
Mikey
Fine with it most of the time and doesn’t interfere with the caffeine habits, though he does comment sometimes. But even he’s gotta admit it gets too much when you don’t sleep for three days, you’re not even studying!
“Dude.”
“What?”
*vauge gesture to your general vicinity*
“????”
“I mean I’ll stay up with you but like-“
“>:[“
“Got it.”

he fits like every symptom, especially the constant need for attention, disregard of others feelings (the entire rottmnt movie) excessive need for praise, inability to handle criticism...
ik this is kinda a hot take, especially since people see npd as 'the abuser disorder' (which is insane and super weird like why is it socially acceptable to have depression but not a personality disorder?! being mentally ill doesn't MAKE you an abuser)
but. but. Leo's got a whole thing going on in his brain. hes got this inferiority/superiority complex, and i think npd is just another way of describing that.
i might post or more fleshed out analysis of this later but for now heres this idea to munch on.
hiii could i request some headcanons for a touch starved!casey jr with a reader who their love language is physical touch [romantic/fluff]? idk i just want to give to my baby a hug, he deserves so much better😭

—————————————————————————
Ever since Kraang was defeated Casey never stopped training. It was ingrained in him since birth that he always needed to be ready for the next catastrophe.
But those were few and far between even with the weird magnet company of the turtles + April! Despite everyone’s attempts at wanting to show Casey the new world he was now in, he would go back to the lair and train until he was sore.
One time Leo tried to keep him out all night which was quite possible in New York since the city never slept. There was an endless amount of possibilities to get into some fun and maybe a little mischief if it involved the blue turtle.
But Casey’s stamina and resilience was equivalent if not better than all of the turtles due to his upbringing. He wouldn’t have survived the apocalypse otherwise. So when Leo finally portaled them back to the lair, barely having enough energy to do so without passing out seconds later, he didn’t get to see Casey’s knowing smile.
The boy from the future easily picked up his younger sensei and got him to bed. Then it was off to the dojo, where he continued to stay up until he felt like he had gotten a good enough training session in. What he wasn’t expecting, was you to be leaning against the circular doorway.
“You know, you may have the worst sleeping habits out of all of them if Leo’s passed out.” You quipped and Casey could only offer a shy smile as he picked up the last of the equipment he had used. “I told him it wouldn’t work… to be fair” Casey muttered.
You didn’t know what to say. Things like, “Kraang is defeated now! And we can take some time to relax” didn’t really compute with Casey even if he agreed. His body just was wired a certain way and he didn’t know if it would ever relax. Even now his muscles which were exceedingly sore, ached for a different reason. He felt restless. He didn’t want to sleep. He felt like fighting. He felt like defending and protecting the city from some new unknown source of danger that was surely building up its forces now
Thoughts like these were driving him crazy. And you could see it. “Why don’t we go out?” You asked and watched as his mouth dropped open, about to refute that such methods didn’t work as Leo had literally just tried all evening to wear him down.
But you stopped him before he could refuse. “Just to a rooftop! It’ll only be a few minutes,” and how could he deny you? As he took you in, it was obvious that you had forced yourself to stay up. Had you been waiting for them to get back? You were in comfy pjs and your hair was a bit disheveled from what he could only guess was tossing and turning in bed. “Alright,” he sighed, shaking his head but continued to follow a step behind with a slight grin.
It was nice to know how much you cared. How much everyone cared about him! But something about you in particular made him feel a tad warmer.
So up to a rooftop you went. The sky was dark and there were blinking satellites that mimicked stars. The city still alive and thriving just as he had left it, but the rooftop was calmer than the sidewalks. It was quieter. He didn’t know if that was a good thing for a person like him. The quiet invited in thoughts that he’d rather not think about. Like his endless worries and paranoia.
He had been sitting on the low rise ledge that bordered the entire rooftop. One foot started to tap anxiously just to offer any kind of distraction when you had sat down next to him, carefully since past the ledge was a seven story drop to pavement. Your proximity eased those nerves somehow and with knees almost knocking, you faced Casey and started talking
About anything and everything! About yourself and your hopes and dreams. You asked about his now that he was here and didn’t have to live day by day. Talking like that made it sound like the future wasn’t always in peril. As if maybe he would have enough time to do other things, like try every restaurant in NYC. And travel outside of the city, even New Jersey which he still didn’t understand why the guys all disliked the place.
The conversation ebbed and flowed naturally until silence overtook once more and this time Casey didn’t have the overwhelming urge to distract himself. Instead he just took a deep breath in and out, letting it go in a long sigh. Then his breath caught in his throat because he hadn’t realized how close the two of you had gotten while talking. Your hand finding his in that moment and your fingers intertwining with his as if it was the most natural thing in the world.
He couldn’t stop himself from looking down at your connected hands, and he shivered all over as you started to trace patterns on the back of his hand. The pressure he had unknowingly been carrying around released from his shoulders. His eyes darted up to yours, finding that you were already there, waiting for his gaze.
In the moonlight he tried to convey his gratitude, because what could he say in this moment that wouldn’t ruin it? He squeezed your hand, comforted by the pressure. Grounded by the gentle hold that you had on him.
The two of you stayed like that for a while. Until your eyelids started to flutter and your body couldn’t stay upright. He of course more than welcomed you to lean on him, but he didn’t want to push his luck and didn’t want to keep you awake any longer when it was obvious both of you needed sleep. “C’mon,” Casey spoke softly, rousing you to try and get you to stand.
But it seemed you were either already out of your wits or maybe just trusted him wholeheartedly because you only scooted closer to him, allowing him to pick you up in his arms and carrying you back down to your bed. Which of course was done easily enough by him since he always had his grappling hook at the ready. It all ended quite too soon for his liking as he carefully let you go so you could snuggle under your covers, rasping out a goodnight to him with your eyes closed.
Would it be horrible of him to admit he had wanted to kiss your forehead so badly in that moment?
After that night, Casey was in for much more than handholding. While that still happened often, hugs became second nature between the two of you. He reveled in your hold, a days worth of stress releasing as soon as your arms encircled around him. Your hands at his back, going up and down in soothing strokes had him holding on tighter when it was time to let go. “Just a little longer?”
He’d shyly ask. If you didn’t want to he would immediately let go. But you always indulged him with a bright smile. So don’t get too mad when he starts to become greedy! With this revelation of him wanting and seeking out your gentle touch, he’d pull you into quiet corners like a true ninja.
One second you’d be in the middle of a Mario kart game and as soon as it was over you found yourself being tugged up and away because Casey had a really important thing to show you or a question that only you could answer! It got more and more ridiculous until Mikey called the both of you out and said you didn’t have to sneak around to hug!
Once PDA was on the table Casey never looked back. He was stuck to your side and honestly, you wouldn’t rather it any other way! <3
oooo. an old but classic thought brought to you by me just redoing my hair fifty times: i can one thousand percent see leo being Incredibly persnickety about the way his mask tails are tied lmao
like donnie is also Highly specific about them but in the sense that he does it a few times at Most and gets it Perfect, and that he chases down mikey to fix any imperfections in the way his are tied, too, when mikey just so happens to pass by the donnies bedroom at the wrong time in the morning
the true Major difference is that donnie just keeps his on the same way the whole day. leo does all kinds'a shit w that thing
first step in the morning is spend fifteen minutes getting it Just Right. but every morning is a Different just right, going no too tight. no too loose. thats tilted to the left a few dozen times before hes settled. but then throughout the day hell loosen it or tighten it or pull it down around his neck. the whole family has seen leo in the bathroom glaring at the mirror a record total of fifteen times in one day, just trying to put it back up and Failing Miserably
part of his Troubles are that he has trouble with tying shit behind him. or at least i like to think so lmao. really good w fancy bows and ties. has trouble w his mask tails every morning. hes just not nearly as coordinated when he cant see his hands man
accordingly if he ever gets really Really REALLY tired of futzing with it hell just badger one of his brothers until they agree to do it for him. it makes him go yay <3 my brother did that for me <33333 all day AND makes sure he doesnt mess w it anymore. bc my brother did that for me though :( you know. donnies willing to listen to leo make highly specific complaints and leos willing to give donnie said highly specific complaints though so he usually goes to him so he doesnt have to go this is driving me crazy . but my brother did that for me :( all day
said old but classic and then added like fifteen new thoughts lmao. i will have to add this to the concept docTM later to keep it all in mind
@cupcakeslushie s FeralLeo Au has me by the throat and I had to get this out of my head.
*************
It's too bright.
Pest hisses and then hisses again, louder, even more agitated, when his voice sounds unfamiliar to his own ears. The echo is missing in this place. Wherever he is, there is no metal to throw his voice back to him in an endless loop.
(sorry I'm sorry I miss you I wanna go home it hurts)
Only stone beneath his feet and hands. Rough where metal was smooth and warm where metal was cold. The air doesn't smell and taste like blood either.
And it's too bright.
This place is different. Everything is different and Pest presses himself further into the corner, afraid and angry and horrified. The big crack in his shell catches against an edge in the wall and it hurts, but it always hurts. It never not hurts.
(that's a lie there was a time when nothing hurt when there was light and laughter and comfort and)
"Leo?"
The word is familiar, but not as familiar as the voices.
Not as painful.
Pest remembers a time when he would hear these voices all the time. He would float in the vast emptiness of the other place, waiting waiting waiting for the next attack, for the next hurt, for the next onslaught of insults and taunts. And he would hear the voices, all around him.
"Leo."
"Buddy."
"Nardo."
"Blue."
He would hear them and he would turn around and around, flailing his arms and legs, calling for them despite his better judgment. Raising his voice brought pain. It brought insults and taunts. It alerted the Big One. But he would call and call even after the Big One found him and he would cry and cry big, fat tears that had nothing to do with the new scars or broken bones.
He called for them, but they never came.
"No one is coming, Pest! It's just you and me! Forever!"
(just you and me just me and you it's better this way it's okay better me than them better me than… than…)
Than who?
Pest thinks he started to slip the moment he stopped hearing the voices. The moment he slapped his hands over his ears and told them to shut up and they did.
Without the voices there was just the Big One. Just surviving.
Survive survive survive.
(why why why?)
Don't ask. Don't question. Just live. Just bite and hiss and scratch. The less he talked and the more he fought without abandon
(like an animal you are an animal what happened)
the better he fared. The less interest the Big One seemed to have in him.
"Wretched pest." The Big One would scoff with disgust and fling him away. Bored.
Bored is good. Bored means less pain. Less attention.
So he became a Pest. He hissed and bit and scratched. He started to fight dirty.
(that's not the ninja way someone always used to say that's not the ninja way but what is the ninja way what is he supposed to do to survive why is he supposed to survive)
Don't ask. Don't question.
Just hiss and bite and scratch.
He sees shapes in front of him. Colorful. Green like him. And red and purple and yellow and orange and brown and so many more. He forgot what colors look like. There were no colors in the other place.
But he can't see more than that. His eyes hurt and his sight is blurry. It's too bright here. The echo is missing.
He is lost.
(no you are home home home you are home)
He is lost and he is scared and he is tired. One of the shapes comes closer. Purple.
"Nardo. Please snap out of it."
The voice is so familiar. He feels like he should know it better than he knows himself, but all he remembers is flailing around in the dark and calling out and crying and the voices going away. Leaving him alone in the other place. Alone with the Big One.
There is still that loop in his head (survive survive survive) and so when the Purple One reaches out to touch his shoulder Pest does what he has to do.
Don't ask. Don't question. Just bite and hiss and scratch.
He lunges.

Imagine this happens shortly before that first post, where Leo kneels on Donnie's back
Oh, my bad, I'm just going blank… I can't think of any.
Let me see… There are some that I don't know if they're common or if I'm the only one with these headcanons.
Transmasculine Leo. He's the family doctor—he's always the one who takes care of everyone when they get sick and he's also the one who bandages them after missions. Leo also has hair, but he shaves it off because he was traumatized by his last experience with hair (and beard, too).
Mikey's hair is magical; the better he gets at handling magic, the more his hair grows. Mikey is resistant to fire.
Donnie is colorblind (I don't know if this is common or if I'm the only one with this).
Raph gave each of his siblings a special plushie. He likes to wear dresses and skirts and other cute outfits—just like Mikey.
okay so my idea is that after the movie Donnie and Leo got really close. After the portal closed and Donnie started crying. I like to think that their twin connection just like snapped and as soon as Leo came back that connection was restored. As a result Donnie started being extremely clingy to Leo, especially during their recovery, anytime something was wrong. Donnie just needed Leo to be next to him and anytime something was wrong with Leo. He just needed Donnie to be like close to him and then things started going getting better. Leo doesn't understand like the lengths of how much Donnie was worried about him because as we all know Donnie is our emotionless bad boy and Leo thinks of him that way too , he mostly just thinks that Donnie's mad at him. Eventually they have this like extremely heartfelt conversation where Donnie finally screams at him and says
" You're my twin. I need you by my side. I can't live without you!"
And like it finally clicks for Leo that Donnie's not mad at him. He just doesn't want to be without him and they have this like extremely cute moment where they just cry in each other's and after this moment they just start being super cringy cliche twins dressing alike, eating alike, talking alike. But everyone accepts it due to the circumstances. Eventually like maybe 2, 3 years later it mellows out and they're not as clingy anymore but like for those 2 years they are so clingy with each other and like having these super cringy like tv-esque sibling moments. That don't feel like real siblings and then like 3 years after things somewhat go back to normal. They still have a little more care for each other than they did before. But now they're acting like actual siblings again and like roasting each other and being mean to each other, but still caring about each other deeply.
This is just something that's been bouncing around in my head for a while I don't know how many of these I'm going to post before my hyper fixation mellows out
