Dad For One AU/ ShiggyDeku Brothers AU

Unfinished!! Feel free to add something in the empty spots for the Characters:)

Just make sure that they don't know Izuku's fathers REAL identity. They can have suspicions, just no actual yk (I'm so lazy lmao)

> WIP!! (This is the updated version, this page will receive updates as this AU grows/I find more information about it, please put any edits onto this page and not the previous one (Old: Dad For Two (All For One)Au ... New: Dad For One AU/ShiggyDeku Brothers AU). If you do accidently add information to the old page, I will try my best to find it and add it to this page! Please put your name at the bottom of the page if you edited it, so credit can be given to everyone! :3)

## Background (idk what to call it lmao)

Izuku Midoriya is the biological son of All For One. Inko Midoriya (Izuku's Mother) is married to Hisashi Midoriya/Shigaraki (Also known as All For One), knowing that he is All For One. Hisashi stole Izuku's quirk the day before he went to the doctors since it was to dangerous for him to handle, and could've possibly killed him when he was still young, hence why Izuku was quirkless until Middle School. Hisashi didn't tell Izuku that he took his quirk because that would cause some augments between each other, so Hisashi decided to give Izuku a secret quirk (Gave him a quirk in secret) half-way through Izuku's Middle School life. Hisashi gave Izuku a high pain-tolerance quirk, making him able to run on adrenalin for about 2 hours and not feel pain, but when the adrenalin ran out the pain would kick in, but be minimized, Izuku thinking that he had developed this as a habit from Middle School from dealing with Katsuki ever since childhood.

Hisashi adopted Tenko Shimura when he was around 3-4 years old (a day after he killed his family), Inko and Hisashi Midoriya looking after him and Izuku. Tenko changed his name to Tomura Shigaraki, taking his (adopted) fathers last name, and been given a new first name by him as well. Hisashi mainly looked after Tomura, and Inko mainly looked after Izuku, leading Tomura to become a villain/the successor of All For One, while Izuku became the successor of All Might. Hisashi was unaware of Izuku being trained by All Might (All For One's enemy), therefore not knowing that Izuku would have his (All Might) quirk passed down to him. Tomura and Izuku started to drift apart as Hisashi trained Tomura to become a villain, Izuku also uncoincidentally drifting away from him to train himself to become a (quirkless) hero, then being trained by All Might. Tomura and Izuku started to drift apart when Izuku was around the age of 7, Tomura being around the age of 12-13. Izuku never really saw Tomura after he was 12 (When Izuku was 12), so he eventually started to do other things by himself to take his mind off his missing brother.

When Izuku got One For All (OFA) passed down to him from All Might, Hisashi's pain-tolerance quirk came in handy for when Izuku used OFA in his first year at UA and the Entrance Exam. When Izuku broke his bones, the area where he broke his bone/s would appear purple or red, sometimes both depending on how bad the damage was. This occurrence was because of Izuku's second quirk (High pain-tolerance), along with the adrenalin rush that Izuku gets when fighting and using OFA (Izuku not feeling pain when he uses OFA, but after the battle collapsing, like in Season 1 when Izuku screams after cleaning up the entire beach, the collapsing).

## Story (Feel free to add on)

Izuku and Tomura were both aware of each others status when Izuku started going to UA. Tomura and Izuku hung out from time to time, Izuku sometimes going to the LOV base (in-secret), sometimes gong shopping for things (Like in the mall scene in Season 2, they both bought some clothes and basic necessities for the LOV).

## The Midoriya Family

All For One - The No. 1 Villain, also the Father of Izuku Midoriya (All For One's real name being Hisashi Midoriya/Hisashi Shigaraki). Hisashi is seen with white hair with black streaks in them, along with red eyes and black pupils. In this AU, All For One is nice to his family, but still with that evil, manipulative side as well. In every AU that I've seen with this format (Every AU = peoples view of this AU), Hisashi looks like his younger self, not needing a breathing mask, and not having any skin tissue around his head and eyes. Hisashi's/All For One's hearing and eyesight are perfectly fine in this AU.

Inko Midoriya - The wife of Hisashi Midoriya/Shigaraki, aware that she is married to The No. 1 Villain. Inko and Hisashi surprisingly have a good relationship with each other, despite their titles.

Izuku Midoriya - The son of All For One, the No. 1 Villain, yet being trained by the No. 1 Hero (How funny). Izuku usually has white and black hair (Natural), but dyes it green, (leaving the black) to cover his fathers genetics. Sometimes, Izuku has a small chunk of hair still white (for some people Head canons), possibly to signify what AU they are using, or just for character design. Izuku is sometimes seen with red or black eyes, other times with green (Different eyes for different people Head canons). Izuku's personality is still the same as the original's, but with a slightly manipulative and evil trait added, making Izuku have some personality traits similar to his father's. Izuku is known for not having a father, since Katsuki sometimes bullies/teases him for not having one. Izuku thought that it would be best for him and his mother to keep his father/husbands identity a secret, using the excuse that he had died before Izuku had been born.

Tomura Shigaraki - The son/successor of All For One, also the sibling of Izuku Midoriya. Tomura was adopted by All For One when he was around 3-4 years old, and was introduced to the Midoriya Family. Tomura has a soft spot for his family, and does not want to kill his younger brother Izuku. The dynamic between Tomura and Izuku is like a friendly sibling one, not like the original universe where they are enemies and want to kill/defeat the other.

## The Bakugo Family

Katsuki Bakugo - Katsuki is unaware of Izuku being the son of All For One, since their family has kept it a good secret (The Midoriya Family). Katsuki knows that Izuku dyes his hair, but doesn't know the real reason why, since Izuku usually makes up an excuse everytime. Katsuki has known Izuku since childhood, and bullied him from Prep to Middle School for being quirkless.

Bakugo's Mom (Mitsuki) -

Bakugo's Dad (Masaru) -

## Class 1A

Ochaco Uraraka - One of Izuku's first friends at the UA. Her quirk is zero gravity. Also thinks that Izuku does not have a father.
