Fallen Angel (My Hero Academia x Male Reader/OC)

Season 1: All Might

3rd person

Ever since Adonis grew old enough to think for himself, he wanted to be a hero. To help people in need, even if it meant sacrificing himself to make sure people are safe.

He found out his quirk at a younger age than most, which got him very excited. His parents saw a lot of them within him, both in the personality and looks department.

He had his fathers facial structure, determination to help people, and later on his quirk — whilst also having his mother's hair and eyes, scary yet caring personality, horns, and quirk.

His parents loved him with all of their hearts, supporting him and helping him become the best he can be. That is until something happened...the white part of his eyes became black, his ears became pointier, skin became paler, and a very disturbing change to his face.

Despite these changes, his mother still loved him no matter what — his father on the other hand, became more cold toward the innocent little boy. Calling him a monster, and stopped helping him on his journey on becoming a hero, saying that he wouldn't become a hero looking like a villain. His mother standing up for Adonis, and for some reason herself included despite her not the one being insulted, only for her to be on the receiving end of some abuse, the same going for Adonis.

But one day that changed...

Adonis's POV

Izuku: "Helllooooo, Earth go to Adonis!" I'm snapped back to the present, as I see Izuku comically waving his hands in front of my face, trying to get me attention "Are you alright?"

Adonis: "Yeah, sorry about that" rubbing my the back of my neck sheepishly, realising the fact that I just zoned out my best friend "I was just thinking about something"

I notice that we're about to come up to a tunnel, so I reassure him I'm fine as we continue waking. He continues mumble to himself about the new heroes we saw earlier, seemingly having his mind taken off of the walking stick of dyed dynamite. Getting to the tunnel, I suddenly get sense of danger, but I shrug it off, chasing it up to me being paranoid.

Izuku: "ADONIS, LOOK OUT!" Turning around, my vision his blocked by a massive green liquid like substance. My eyes widen in shock, but before I know it, I'm pushed out of the way before I could get grabbed. I land on the floor and turn to see that the monster had...GOTTEN IZUKU!

Adonis: "IZUKU!" Shouting out to my friend being held by the green sludge, I held my hand out for him to reach only for him to get submerged even further into the slimy green substance, and the monster backing further away.

Sludge Monster: "Nuh uh not so fast, this child will be my host, so I can escape this city, and get away from him" As he says in his disturbingly gargled voice, I see Izuku slowly slipping into unconsciousness with tears in his eyes.

I stand there watching as my best friend is slowly being taken over by a villain. One of the only people kind enough to give me a chance...

My breathing becomes heavier, as my quirk activates itself. My razor sharp claws ready to grab the monster. Tail ready to choke the life out of him. My face getting hotter, and steam slowly coming out of mask.

The monster notices my change, and is startled at the fiery glare piercing straight into his slimy soul. Beginning to back up, the villain looks at me in fear, as I slowly make my way toward him with killer intent practically oozing off of me. As I'm about to strike, from behind I here...

???: "Have no fear, young ones, for you are safe!" I turn to see a tall muscular blonde man with two stands of hair sticking up at the end of the tunnel behind me, my eyes widen as I recognise who it is...All Might "now that I'm here, that is! Stand back kid, things are about to get serious"
