December 23rd, 21X4]
The doctor's office is cold and sterile. Izuku can feel his legs going numb from where they dangle off of the examination table. The doctor has been gone a long time, and his mother seems to be getting more anxious by the minute.
Just as Izuku goes to ask his mother if they can get sukiya after this, the doctor comes back in.
“Mrs. Midoriya, Young Izuku. I have good news, and I have bad news.” He says, closing the door behind him and sitting down in the little wheelie chair meant for the doctor.
“The good news is that Izuku technically does have a quirk. The bad news is that it’s… incomplete, for lack of a better word.” The old man says, cringing slightly at his own lack of word choice.
“What does that mean?” His mother asks, worriedly looking at the doctor.
“Little Izuku here only has parts of his father’s fire quirk. He’s highly resistant to fire. We had to use white fire for him to even display a slight reaction to it, and blue fire for him to become injured; even then, it was only minor burns. His mouth seems to be the most resistant, not burning unless prolonged exposure to blue fire happens.” The doctor begins to explain.
“His skin is incredibly tough, and is even starting to look like small scales in places like his joints and the high points of his face. His canines appear to have some much sharper ones waiting to come in with his adult set as well.Obviously, you can see his slitted eyes and claws, as those are his most obvious mutations.” The doctor grabs Izuku’s arm and starts to show them where tiny iridescent flesh colored scales have appeared on Izuku’s arm. The scales shimmer a pretty pale green as his arm is moved.
“Unfortunately, that’s where his similarities to his father’s quirk stop.”
Izuku’s heart is beating so fast it feels like it’s gonna explode.
“Izuku’s gas sack and spark membrane are underdeveloped. His gas sack isn’t fully developed and has no exit hole for any gas it builds up, so it just doesn’t produce any. His spark membrane is too thin to properly use, so even if Izuku’s gas sack was fine, he’d never be able to ignite the gas and breathe fire.” The doctor says, a pitiful expression on his face.
And Izuku’s heart shatters.
“I’m sorry, Mrs. Midoriya. I am going to be classing him as a non-lethal mutant type quirk; only D tier due to his claws, thankfully.” The doctor says, standing up and opening the door for them.
Izuku’s mother thanks the doctor for his time and picks Izuku up, rushing out of the office with him.

“Hey! Izuku! What did the old man say about your quirk?” Kaachan shouts to him the next day at school.
“Oh, uh… I have an, uhm… underdeveloped dragon quirk. I’m fire resistant. I have scales, fangs, claws, and the eyes like my dad, but I…” He trails off.
“You, what nerd?” The blonde presses, getting up in Izuku’s face.
“...I can’t breathe fire. I won’t ever do it. S-Something about my gas thingy and my uh, fire starter? T-They don’t work right, so I can’t make the gas needed to make my fire.” Izuku admits, turning away from Kaachan in embarrassment.
“WHAT?! We were supposed to be heroes together! Now you’re saying you’re useless?” Kaachan yells, getting even closer.
“K-Kaachan! I–!”
“No! You don’t get to talk to me! I won’t talk to some loser who’s basically quirkless! You’re a deku now!” The blonde yells even louder, sounding angrier than Izuku has ever seen him.
Deku.
Deku.
Deku.
Kaachan called him a… a deku.
Kaachan thinks he’s useless.
Mom said no one would think any different of him.
He’s still the same Izuku, right?
