Todoroki one shots + other random fandom one shots

Transformed into a child

Summary: (Demon slayer Todo AU of course) So Todoroki's backstory is that Shoto was abandoned by his family at age 7 so he was raised by Sakonji Urokodaki for a year when he got attacked by a demon making him lose his memories of his biological family, then he wanted to train to be a demon slayer when he met Sabito, Makomo, and Giyuu. Villain rehab with the League of villains are here 

No one's POV

Aizawa is going on patrols when he stumbled upon a little boy in a black cloak with a half blue, half white and red haori with black Hakama pants with a weird black uniform thing with the back was a word called 'Destroy' and a pair of white zori with black tabi socks a little oversized, the boy was around the age of 9. "Hey kid why are you here?" The pro asked "I got lost while finding a way back home" the child said pulling down their hood making the pro hero shocked seeing that one of his students has been de-aged around 7 years. "Listen kid it isn't safe around here so lets head over to the school I work for" Aizawa asked "sure, I can find my way home tomorrow" the small child said making Aizawa feel better. 

When they got to the dorms

The hero and the child went back to the 1-A dorms and they are greeted by the villains and the class playing games while the League is just talking "hey Mr. Aizawa who is the kid you have in your arms?" Mina asked getting everyone's attention "it kinda looks like Todoroki" Momo added "this is Todoroki, he probably got hit by a de-aging quirk making him 8 or 9" Aizawa explained shocking everyone even the League shocked. "So your saying that a 16 year old who is the son of Endeavour and is a hero in training got himself hit by a quirk" Shigaraki said and Aizawa confirmed "who's Endeavour?" Shoto asked making everyone confused as he got out of Aizawa's arms (he was in Aizawa's arms because he thinks Shoto was running a lot so he carried him incase he was tired) "your father obviously" Toga explained "but I'm an orphan" Shoto explained. "No, you are not I saw you in pictures with Endeavour's family" Dabi said "I don't know who my real family is" Shoto added has his haori fell off him and Deku put the haori back on his shoulders "thanks" Shoto thanked Izuku putting his haori back on his haori. "You know what it's getting late for a child your age so lets get you too bed" Aizawa said trying to pick up the de-aged Todoroki but he swatted his hand and kicked him in the stomach "AH, MR. AIZAWA" Uraraka screamed making the students running over their teacher who is holding his stomach in pain. "Damn the kid can kick" Aizawa complimented recovering from the kick as the small child pulled out a long light blue sword "HOLY SHIT WERE DID HE GET THAT?!" Spinner yelled as Shoto tried to escape the building but Dabi restrained him softly trying to not harm his younger brother upset that his little brother probably not remember him or his other siblings. "Let me go I need to find Urokodaki-san" Shoto pleaded "what if he doesn't want you? Think about it he would try to find you knowing it is late" Dabi asked "he knows it's training I get back home before the sun rises everyday and I always get back before 5" Shoto explained making Dabi confused. "You know what I'm taking the kid back to my room Tomura if they ask where he is tell them he is with me okay?" Dabi said as Shigaraki put a thumbs up and Dabi picked up his little brother and humming the lullaby that their mother used to sing to them when they were injured and it made Shoto slowly calming down and relax. "That song sound familiar to me but I can't remember why?" Shoto asked himself "it's probably because you know what the song is from your real family" Dabi explained "I don't remember who my real family is but I want to know who they are since I was found in a forest when I was 7 but I don't know why, when I found out I actually had a biological family I asked Urokodaki is I can train under him and maybe one day my biological family might recognized me and I could know what a biological family feels like" Shoto explained to the scarred man. "Hey Shoto I'm going to let you in on a little secret, I am your oldest brother but our family doesn't know that I am since I ran away when you were 6 I don't think they recognized me yet but I am planning to reveal my identity one day" Dabi explained making the little child lit up. "I actually found someone who is related to my by blood" Shoto exclaimed happily jumping on the black haired male who was surprised but huggedd back happy now knowing his younger brother knows him "thank you little Sho" Dabi said as the two brother fell asleep.
