Poly! Yandere Headcanons: TodoDeku

- Izuku is Clingy and Delusional while Shōto is Possessive and Obsessive. The way these two would combine would mirror two parents protecting their baby. With Izuku being clingy and delusional, he will think he knows what's best for you and a good chunk of it is also listening to Shōto. Don't get me wrong, don't think you're the only one dealing with his BS but Shōto is obsessive and possessive so he can calm Izuku down. You don't have that luxury. Shōto will also think he knows what is best for you while also spoiling you and Izuku, which will only encourage Izuku's delusions.

- For starters, the Dom is obviously Shōto. It doesn't take much for him to get either of you to submit–especially in bed. The dual, the one who is okay either way, is Izuku. He doesn't mind being submissive to Shōto but he does want to dominate you. You are the sub in this. You just had to catch their attention, huh? Don't worry, it's not all your fault and they aren't cruel to you. (Izuku would never forgive himself if he was.)

- This relationship occurred originally without you. The two accidentally learned that the other had done some less than pleasant things for the other and realized the feelings were mutual. To be fair, the signs were always there but Yanderes be paranoid. Then they met you. You were more than likely a transfer student or perhaps you were related to someone on staff. Either way, they both loved your kindness but they always questioned your homelife. Your non-hero parent had been instilling odd and sexist things into your head for years and once those two found out... that was it. They knew they both had a crush, after talking about it cause again paranoia, and they knew you had to belong to them. You had to want them!

- Together, their behaviors really balance out. When it comes down to it, you can see how Shōto's type and Izuku's type are mirrored, Shōto's appearing more masculine than Izuku's. You don't really catch it for a long time. Izuku will like hugging you and showing PDA which will lead to Shōto joining to remind people who you and Izuku belong to. You see it as normal since people won't always assume you're in a poly relationship. You don't look it. When you start seeing it is when it gets suffocating like how descriptive Shōto is about you and Izuku that it's just plain creepy, when Izuku says things you're not ready for and he claims you are–claims Shōto is ready for, and worst of all is how you realized that they were a bit on the down end, there was a shrine dedicated to the three of you in Shōto and Izuku's home. Now that's hella creepy.

- Shōto will use his Ice, the pictures, and some secrets against reader while Izuku is iffy. Honestly, if anything, he'll ignore what ever was causing it and use his own force against you...personally, I wouldn't trying fighting at that point cause he's A ONE FOR ALL USER. There's a chance he'll accidentally break your bones, ya know?

- Izuku will definitely argue about the blackmail. He isn't big on manipulation tactics and is okay with the ice simply because he uses his own strength. Why should he do it and tell Shōto not to? That didn't make sense.

- You were kidnapped later on. It was a simple day, school was ending. Afterwards you went out for ice cream and didn't notice the sketchy man who was in the back who prepared it. Bribed. You got sleepy and fell unconscious from eating the delicious treat. When you woke, you were in a room that had a huge bed and there were scented candles all around. The sheets were silky and you were in a cute dress/adorable suit. And a collar.

- You cannot escape these two. One is always home at all times and if it's Shōto there's no way in actual hell you can. With Izuku, there would've been a chance if it weren't for the size of the house. They won't react kindly to your...attempt..

- Izuku would attempt punishment, but fails. If Shōto is home he will say no to whatever Izuku was going to do immediately and claim 'you need more loving' when he knows you already feel suffocated. That is reserved for behavior but during escape attempts, Shōto and Izuku will both be home and Shōto will coax Izuku into punishing you sexually–taking pictures. Oh, don't think he's pleasuring you. Neither of them will do that, no, they're taking pictures of you nude. What will happen if it goes out? (Again Izuku is huffy about this)

- usually Aftercare for behavioral punishments is letting be alone for an hour–you appreciate that. If it's an escape attempt kind of punishment, it usually starts with Izuku wrapping you up in a warm cozy blanket, Shōto getting you some comfy–and very covering–clothes. If you're crying, they'll play with your hair or gently rub your shoulders and back. They'll say you were a good boy/girl in soft tones and cuddle for hours on end. SEXY TIMES aftercare is typically cuddles, lit candles, reassurances depending on if you did any kinky kinky stuff. Usually it's Shōto to you and Izuku and you two have reassure him you're fine and that Izuku is fine and that you both still feel safe. Also may include some soft feel show whether it be a comedy or cartoons, it helps. You may also talk about making things more intense, maybe asking not to do certain things, and trying one thing extra next time. Shōto typically falls asleep first and you and Izuku may giggle at how cute his sleeping face is. Eventually you fall asleep then Izuku. Yep aftercare is nice.

- Shōto doesn't hesitate but Izuku will avoid killing if he can. Izuku will scold Shōto here and there depending who it was. Normally they get over it quick, it was already done.

- If Izuku snapped, he would potentially hurt both you and Shōto, cry about it, but would definitely get extra paranoid. At some point you would be too scared to speak to him and Shōto will try to fix it. This will end in Shōto keeping Izuku in the basement for awhile until he calms down. If Shōto is the one to snap, you wouldn't get hurt because he'd be extra. Izuku and you would be confined into a room and you would freak cause you'd smell blood and his fire. Izuku would try comforting you. He would hold you and try to calm you. If both of them snap, you will not exactly be safe. The best advice is for you to cooperate and relax. If it gets too much, don't be afraid to cry, it would be better to cry than to lash out. Usually this snap won't last long because after awhile, Shōto will see Izuku's behavior long enough that it snaps him out of his own insanity and he will proceed to do what he does to calm him down. There will be some spoiling but this will never leave your mind...ever.

- With Izuku, he isn't the most sexual. This is mostly due to his moral compass. Shōto is, but he's a traditional boy in this regard and wants to wait until all three of you are married.

- Neither will force themselves on you if you're not all married. If you are married, Izuku still won't because he doesn't want to have that on his conscience but if it's Shōto? He won't care, you're married now. Of course, this is punishment and if Izuku denies it guess who is getting punishment with you? Yep, scary...

- The kinks typically used are overstimulation, BDSM, roleplay, petplay, occasionally degradation, and creampies.

- They like giving their affection through hugs, kisses, gifts and on your B-Day they make everything about you. (Especially in bed.)

- Once you accept the two, find life is incredibly easy. You stay home and enjoy life. They don't mind you doing at home jobs like writing or such. It feels normal...except occasionally one them comes home with some blood. You may discuss kids, it will happen. If you're able to be impregnated then you'll be having one baby first. Honestly, it's a coin toss. If you're male, you all go and adopt at most three children. You are the stay at home. You are literally just spoiled and you will spoil your children. Izuku and Shōto don't stop you because they're also spoiling them. Shōto isn't fond of the idea of any of them wanting to be a hero but doesn't say it out loud to them. Izuku encourages 'a job that makes you happy' and you say "No job exists that has no competition, if you want a job when you're older, prepare to be the best you in that job. Not number one but the best you you can be."

Also, lots and lots of vacations. Usually you pick the spot.
