Deku

He pouts and gets all clingy. He basically acts like a spoiled child, and he knows damn well what he's doing when he whines about lacking your attention. Deep down, though, he's doing because he's self-conscious.

Todoroki

The moment anybody makes a move on you, or if he sees anybody as a threat, he goes to your side and kisses your temple. His cold glare is normally enough to pierce any brave souls in their core. But, if someone isn't getting the hint or challenging him, one of two things will happen.

1. You have a jerk Popsicle

or

2. You have a jerk done medium-well

Bakugou

Lord can only pray for mercy on this fool's soul. Much like actual pomeranians, Bakugou does NOT like sharing. He has bitten people before for touching you. Game over if they actually grope you or try to get you, not even Satan can save their stupid ass at that point.

Kirishima

He flexes his arms when he hugs you, sometimes even using his quirk. He makes it known that you are his and will fight the jerk if he gets too close. He has also been known to give some pretty scary smiles.

Denki

He can and will shock the person after a verbal warning that you are his lover. It has gotten him in trouble, but he doesn't care. You are his, and he will make sure nobody interferes with that.

Iida

His brows twitch and he often tries to find an excuse to get you and him away from the person. He'll say that you two need to go outside for a bit, or that somebody was waiting for you.

Sero

He's pretty chill at first, telling whoever it is that you are his lover and that he doesn't appreciate the flirting. However, if the person keeps at it, he will tape their mouth shut and escort you away.

Koda

He normally doesn't leave your side, so it's pretty hard for anybody to get near you. Even if someone did get close enough to try to flirt, Koda's appearance is actually pretty intimidating despite his shy demeanor.

Sato

He does his best to remove you from the situation, but if it escalates he will intervene. He knows you get uncomfortable with random flirting, so he does his best not to draw attention to you.

Shoji

Much like Koda, his appearance is too intimidating for many people to approach. On the rare occasion that someone does try to shoot their shot, he just tells them in a low voice that you are taken.

Ojiro

His tail comes in handy, since he often wraps his tail around you when you're together. He'll swat anybody who flirts with you away, he isn't big on confrontation. If someone decides they want to fight, that's a different story.

Tokoyami

Dark Shadow shields you from view and he gives the man a verbal warning. The scary quirk plus the mutation are often more than enough jerk repellent.

Shinso

He'll brainwash them to pour their own drink on themselves and sweep you away in the chaos. You think it's funny how his cheeks puff out when he admits he was envious of their looks.

Tamaki

His self-esteem takes a hit if someone flirts with you, but he still holds you close. He'll snuggle into your body and give them a piercing glare, sometimes even allowing some tentacles free for extra scare factor.

Mirio

This man will be unusually calm as he takes the jerk by the shoulder and escorts him away. His smile couldn't fool you, you knew he was gonna punch the guy out the moment they were alone.
