Illegitimate Todoroki (My Hero Academia Male Reader Insert)

A Surprising Mistake

A/n: So guys who should (Y/n) have a relationship with? The only thing is they have to be enrolled at U.A. Please leave answers in the comments. Anyway let's get this started.

There is a woman with white hair pacing back and forth in her bathroom. There is extreme worry going through her as she waits for her pregnancy test results. It seems for like an eternity for her as she waits. She finally looks to the test to see its positive, this was the forth test she's took and they were all positive. Generally this wouldn't be an issue except for the fact she knew that this child wasn't her husband's child. She truly began to have a panic attack at this point.
-10 months later-
After several hours of labor (Y/n) Todoroki, son of Rei Todoroki is born. However, it is very clear the moment she sees her new child that he shares nothing in common with Enji Todoroki. Rei's heart melted upon seeing her new baby boy but then she felt fear as she took in his features. His hair was black with white tips and had bright green eyes leaving her no way to lie about who he belonged to. Though for a bit that fear vanished at the smile on her infants face. The doctor came back in with Enji and upon seeing the child his face changed to one of anger. The doctor soon left the room to give the two a moment but instead the room soon filled with shouting and crying.
-4 years later-
(Y/n) despite everything was still living in the Todoroki home. However, he is just known as (Y/n) as per Enji's anger over the illegitimate child that he was adamant he wouldn't be known as a Todoroki. Though (Y/n) wasn't allowed to have dinner at the same time as the rest of the family, his siblings and mother would accompany him for his dinner to make him feel included and thus, he became close with his siblings. Unfortunately things began to go downhill as one of his older brothers ran away, Shoto was beginning to get isolated from (Y/n) and their mother, and then the incident happened. (Y/n) was walking through the home one day when he walked past the kitchen a scream rings out and (Y/n) rushed in to see a horrifying sight. His mother was pouring boiling water on Shoto's face. Thinking quickly (Y/n) got between the two and shoved his mother away from Shoto causing the rest of the water to be dumped onto (Y/n)'s arm. She looked to her children after stumbling back and her face shifts but, not to one of anger but of surprise as she covers her mouth and her eyes widen. She reaches forward which causes Shoto to cower behind (Y/n). She began to cry as she tried to walk towards Shoto again while saying.
Rei:"I'm sorry I..."
She was interrupted by (Y/n) who put his scalded arm up in front of him as he just stands there between the two and says very lowly.
(Y/n):"Please don't hurt Shoto, Mommy. If you need to hurt anyone, just hurt me instead."
She feels her heart break as (Y/n) said that but before she could say anything Enji came in and looked to the two children and said.
Enji:"You two go to the living room."
(Y/n) just took Shoto with him and they went into their living room and just waited for one of the parents to come back in and assure that everything was okay. It didn't go that way though. After that day their mother was sent away and Shoto was isolated from (Y/n) and they saw each other very little. (Y/n) also started going to school with his other siblings besides Shoto. (Y/n) was walking home with his sister and other older brother from school and passed by another school's playground. (Y/n) looks over and sees five kids there and one with scraggly green hair is protecting one from the other three. He just watches them as they continue to talk until (Y/n) realizes the three were going to beat up the other two. So, unbeknownst to his siblings he slipped off to help. Before the boy with blonde hair could hit the boy with green hair a wall of ice appeared between the two. They both look to the boy with black and white hair and green eyes as he says.
(Y/n):"Leave them alone please."
At this the three bullies show off their quirks as if they aren't worried about him. At that purple lighting began to pop and crackle around the right side of his body as his face remained unworried. The three just began to shrink before they turned and walked off after that (Y/n) got rid of the ice wall and the lightning slowly dissipated, when he heard the green haired boy say.
???:"That was amazing! Thank you so much."
(Y/n) just says rather nervously.
(Y/n):"Um n-no problem. I gotta go see ya."
???:"Ok see ya later."
After that he walks back to his siblings who just look to him surprised as his sister asks.
Fuyumi:"(Y/n) did you just use two quirks?"
(Y/n) once again gets nervous and says.
(Y/n):"Um y-yeah uh why?"
Both his sister and brother look dumbfounded as his brother then asks.
Natsuo:"How long have you been able to do both?"
(Y/n):"Um well ever since I could make ice I could also make electricity."
They both looked surprised at their little brother and they both decide to tell Enji.
-Later that night-
(Y/n) was sitting in his room playing with some toys until he hears a knock and opened the door to see Enji who asks.
Enji:"You're sister told me you have two quirks."
(Y/n) responds very afraid with the best manners he can muster.
(Y/n):"Um yes sir."
It was always clear that Enji didn't like (Y/n) so, the fact he came to talk to him at all about his quirks was puzzling. Then Enji simply responded with.
Enji:"Would you like some help training it?"
(Y/n) looked to him surprised, before Enji said to the child.
Enji:"Don't just sit there gawking. Do you want to train with Shoto and I or not?"
(Y/n):"Uh yes sir that would be great."
Enji:"Good, we start training tomorrow."
Enji then left and (Y/n) began to jump up and down happily at thinking this was an act of kindness from Enji. If he only knew the reasoning for allowing him to train and that the next several years of his life would be nothing but hellacious training he might've reconsidered.
