Your worst nightmare disguised as a fantasy

:: LEONARDO

When you warned him that your brother can be protective, he thought you were exaggerating. He would wave off your warnings and assure you he got this. He's Leonardo, he can prove to your brother he's worth your time.

He was wrong.

So wrong

After "The shovel talk" He would hesitate to touch you whenever your brother was in the same room. He would laugh off your worries and say that he's fine.

I guess he now understands what it was like when you had the talk with Raph.

:: RAPHAEL

He was nervous. He wanted to look good, act good, and smell good. Only two of those objectives were achieved. His brothers tried to help by suggesting ways to help him calm down, which only helped a bit.

Your brother didn't help with this rising panic at all.

He would be determined to gain your brother's trust but wouldn't know how to. The only way he knows how is by having your back on physical problems, financial problems (Which he doesn't know how to solve but he tries), or emotional ones.

Which in time he did earn your brother's trust.

:: MICHELANGELO

He was so optimistic when he heard that he was going to meet your brother. He thought it was like someone is being added to his family.

He never knew he would feel so threatened by a straw.

Like Raph he wants to be close to your brother but he's just so menacing he swears he can see kanji signs around him.

He would now cling to your arm whenever your brother is near to have some comfort and protection from him.

His brothers don't like your brother, and your brother reciprocates that hatred 100%.

:: DONATELLO

The definition "I fear no man but that thing, it scares me"

He thought he was being slick when he shows up to your brother in style and prepared 100 good jokes to appeal to him. But it was all a waste as your brother soon threatened him with how he is going to turn his shell into a soup bowl in excruciating detail the moment you left the room.

Traumatized and speechless, he left your house with you in a matter of milliseconds.

:: DONATELLO

Out of the four he has the biggest robust for attention that he never had from his family when it comes to his passion for science. He would constantly seek his partner's presence and would absorb any sort of praise given to him by them. It soon turns into a rewarding system that if you ever praise him for his work he would help you with any problem you may have with help of his inventions. No matter how mundane it would be Donnie will always have the solution for any inconvenience. But if the situation calls for a more physical solution Donnie would volunteer to solve it himself with the help of his staff and Sheldon to clean up the mess.

Has a vicious jealousy streak, any sort of compliment that is not directed at him leaves him to believe that the person you're complimenting is more superior which stirs up feelings of malice and envy. The most he would do is grind his teeth and nearly break anything that he is holding with how tight his grip is before sending the offender to the hospital for broken legs and ribs. After the incident, he would avoid you for a good two days before approaching you like he wasn't ignoring you a while ago.

Romance won't happen naturally as Donnie is not one to get attached easily, he might have even started as a platonic yandere. Not ever seeing you in a romantic light until a joke or comment about you two being a couple would come out of his brother's lips before questioning the nature of the relationship. These obscure feelings would taunt him for a while prompting him to be alone. Soon enough any sort of physical contact (Like a hand on his shoulder or leaning on his side) would leave him flustered and embarrassed.

Donnie would be one of the more controlling yandere as he thinks he's entitled to make a schedule suited for you which includes always spending time with Donnie or with his brothers. If you are human he would invite himself into your apartment without you ever knowing and sneakily check your calendar or notes to see what time you are free so that he can invite you into the lair.

One of Donnie's love languages includes gift giving which means he is willing to upgrade your current gadgets to the latest model whether you agree or not. This is a 50/50 that even though your phone (Or tablet, laptop, etc.) may have more storage than any Terabite Donnie might have implemented spyware that only he knows how to dismantle. So now he can look at what you are watching, chatting to, and reading on your gadget of choice without getting caught by you. If you are ever chatting with a friend who is not one of his brothers or April, Donnie would mistake what is most likely envy as a sense of malicious intent that you seem to overlook. And it won't be long until he has their address and see if he can find them in NCY.

Your online friend who lives in another continent: *hears a knock on their door* *Opens the door* Yandere!Donnie: Hello, I would like to notify you about your car's extended warranty :] Your online friend: I don't even own a car-

It's common knowledge that Donnie is a stalker and is pretty lucid that this is not right. His morals are grey and he knows that sometimes people have to do bad things for the right reasons, he would like to think that he's a part of that group but he knows deep down he isn't and that what he is doing is still horrible. He would also be the bodyguard that you never knew you had, if you are human he would demand you stay home or preferably with him and his brothers at the lair. It would double if you are also a mutant and would even make you a room in the lair with the help of Mikey's creativity. Denying the offer wouldn't matter as Donnie will take hours of your day until you are forcibly moved into the lair.

He doesn't need to kidnap you if you are a mutant as you are now part of the family, the brothers are supportive of the relationship as Donnie is an expert at hiding his obsessiveness and knows just how unhealthy the relationship is with how much he did to maintain control over your choices and connections. But if you were human it would be worst as you have a life outside of the relationship you have with him, you have people who can make you know that your relationship with Donnie is not healthy if it makes you feel like he's watching you right now and he is. You two may have frequent arguments about Donnie micromanaging your life, and if it ever leads to you breaking up with Donnie, Donnie wouldn't know what to do with himself.

Most likely? No, definitely going to kidnap you if you ever show signs of wanting to break up with him, especially if you say it to him straight up. He has grown so attached to you and you have already known what you were going into with dating him (you didn't know him being obsessed with you is part of the deal but smh) and there is no way things are going to go back to "normal" after this.

"You really should've thought twice about leaving," Donnie stated, his voice echoing through the empty dark room as he fiddled with one of the cameras resting on his palm. You struggle to rebuke with the gag placed on your mouth, lashing around the restraints trying to break free from your confinement but none avail.

"You wouldn't even be in this circumstance if you just listened to what I said." Setting the camera up on the ceiling you could see it flicker on meaning it has activated.

"There, so now I can know what you're up to when I'm away." He stated proudly before facing you with a look that was similar to a mother staring disappointedly at her toddler.

"I'll be going to the main room to not arise suspicion from my family, while you stay here and think about what you've said." After finishing his sentence Donnie placed a chaste kiss on your forehead as you recoiled back from him, revolted from the action.

"Ok, rude," Donnie mumbled to himself before walking away, typing the exit passcode of the room you were confined to with surprisingly high dexterity.

"Mikey is going to make dinner soon, I'll make sure to save some for you."
