Hybrids have human characteristics but also possess animal qualities; some have ears or horns, others wings, and still others tails, depending on their animal origins. Because of these traits, they have natural instincts and tend to be territorial or aggressive.
(Some animals experience what is called "heat". And this is still maintained in hybrids of these types of animals)

Loud or intense “look at me, look at me” type people.

Pressuring him to talk when he doesn't want to makes him even more withdrawn.

Hypocrisy… that pisses him off more than it should.

Places full of people, like school recess… personal hell.

They underestimate him. The guy is smart, but he doesn't go around bragging.

Showing weakness in public, even when it is clearly present.

Waking up early… that guy lives in zombie mode before 10 am

The mistreatment and how they hunt hybrids even though there's nothing they can really do.

Sad or strange music, the kind that nobody understands but he says "this represents me".

Draw or write things that are kind of dark (but pretty, obviously).

Silence… loves being alone, but not just alone, just without stupid people.

The rain, because of course, it's the main character in anime.

Drinks like coffee or bitter things, to feel more grown-up than he is.

He takes great care of the few people he likes (even if he doesn't say so).

Black clothes, oversized, anything that says "don't talk to me".

Hybrids.

Bats (fascinate him)

He usually plays in a band with his four friends. He likes playing guitar.

Intelligent, but too lazy to show it. He gets good grades without much effort, the kind of guy you dislike for that reason.

He's a good person to those he likes: he helps you with tasks, listens to you when you're feeling down, and doesn't judge.

Dark humor, it throws out strange comments that make you laugh and worry at the same time.

Loyal. If you're their friend, you've already gained a free emotional bodyguard.

He looks like he could scare someone... but he'll probably actually buy you something at the soda shop if you forgot your money.

He always wanted to meet a hybrid and take care of it, so if he finds one he will probably take care of it and keep it without complaining.

Light blue hair, somewhat disheveled, like "I woke up and this is how I ended up", but it clearly took him a while.

Pale skin, almost ghostly, as if she never saw the sun, not even by mistake.

Dark eyes with a strange look, like tired or somewhat disturbed… but chill.

She wears oversized black clothes, a large sweater that looks like she stole it from another dimension.

Long hands, with rings and bracelets, full depressed Tumblr aesthetic 2014.

He had a strange, hunched posture, as if life weighed an extra 50 kilos on him.
