Tenko Todoroki Au

This AU contains 5 outcomes.

## The Beginning

After killing his family by accident, except for his father since he killed him on purpose, Tenko went to the streets and after some time, he was found and adopted by Endeavor before Toya's "death", he became friends with all his siblings, especially Toya, Tenko also met Hawks, since he was really close to Toya, he was happier than he was giving up in being a hero because of Endeavor, but he had other plans for Tenko. After some months, Endeavor dragged Tenko to a lab and gave him to some scientists, he told the scientists to give him a quirk like Shoto's. Some months passed and Tenko became aware of Toya's "death", his appearence changed a bit, his hair turned white and his right eye turned lilac purple and his left one became grey purple, but after hearing that his closest sibling died, part of his personality changed too, he also was forcefully gaven the quirks Endeavor wanted him to have, some of his siblings and Rei also visited him, before Rei was put in a hospital.

## Outcome 1: Villain(Tomura Shigaraki)

He couldn't take all of what happened to him and ended up losing control, killing the scientists of the lab and fleeing without looking back. After hiding in the streets, he was found by All for One, but Tenko was scared because if a hero treated him like that, imagine a villain, but after All for One convincing him that he would have a better life and would take revenge on this corrupted society, he accepted and All for One changed his name to Tomura Shigaraki. He dyed his hair blue and put red contact lenses in his eyes and hided part of his scars and never used his gaven quirks, unless he was forced to or accidentally used them.

## Outcome 2: Villain(Kyosei)

Just like the outcome 1, he lost control, killed the scientists and fled, but instead of being found by All for One, he found Toya, the two nearly didn't recognize each other because of the scars and new appearences, the two hugged each other and Toya told him about becoming a villain and taking revenge on their father, he also told about Stain and how he admired his ideologies, so Toya told him to only call him by the name Dabi and Tenko choose to be Kyosei, that means forced, because of Endeavor forcing him to have the other two quirks. Kyosei became a spy for Dabi, secretly taking information and working on his own or for Dabi, even when Dabi joined the league, Kyosei didn't join them because he doesn't want to be known or found by the rest of the family or maybe even other Pro Heroes.

## Outcome 3: Hero(Tenko Aizawa/Rust)

The same in outcome 1 and 2 happened here, but instead of killing everyone and fleeing, some scientists survived and managed to call the pro heroes, they went there, Eraser was one of those heroes, while Tenko was burning everything around him and losing his mind, he erased Tenko's quirk and approached him, telling him to calm down because everything was okay, then Tenko proceeded to let out all of his pain while he cried, Aizawa hugged him and calmed him down, telling him that he wouldn't have to suffer anymore. After that, Aizawa adopted and trained Tenko, since Tenko couldn't control his quirk and wanted to be a hero. Tenko started to admire Eraser Head and often called him "my hero" because he saved him from the scientists. While in U.A., Tenko caught All Might's attention because he reminded him of his master, Nana Shimura, not even knowing he's her actually grandson, All Might gave Tenko the One for All quirk making him the 9th user, but don't think Midoriya didn't gain the One for All, he just became the 10th user instead of the 9th. He didn't choose a hero name, he prefered his own name to be known instead of a codename, he also refused to use his fire quirk, saying that he only has decay and ice to his classmates, teachers and students. He used to work with All Might, and after being inspired by his father Aizawa, Tenko decided to become a U.A. teacher, waiting for 3-A's teacher retire like they said they would so Tenko would take the position.

## Outcome 4: Hero(Tenko Todoroki/Stardust)

He didn't lose control like in the other 4 outcomes, he just waited until it was over, and some days later Endeavor took him back home. He entered U.A. in the future just like he wanted, but he refused to use his fire quirk, saying that he only has decay and ice to his classmates and teachers, when he finished college, he became one of All Might's sidekicks, when he retired, he worked for Sr. Nighteye, after Nighteye's death, he started working with Endeavor, but just because Shoto was in hero work studies in there. Tenko choose the name Rust because of his quirk. Tenko likes to prank his father, filling his office with All Might figurines and putting the blame in one of the other sidekicks or maybe even Hawks.

## Outcome 5: Hero(Tenko Bakugo/Ash)

He also lost control in this one and fled, but instead of becoming a hero, he was found by Masaru Bakugo, who felt pity for him and decided to take him home and adopt him, Mitsuki didn't like him at first because she though he was too weak and scared, but after Tenko told both her and Masaru about what happened to him, she understood more about why he was so scared. Him and Katsuki had the dream of becoming heroes, but differently of Katsuki, he never bullied Izuku because he was quirkless, instead, he would always interfere whenever he saw Katsuki bullying Midoriya, Katsuki was scared of him so he would always back off whenever his big brother came to stop him from doing bad actions, Tenko always scold him and use the traits of a hero to show him why this actions were bad. Thanks to his mother and sibling influence he became a little explosive with the ones not close to him and with the ones close to him he's a bit nervous, but he does show he cares about them, he also had a big sense of justice, which caught All Might's attention, and he gave Tenko the One for All before he entered U.A., becoming the 9th user, while Midoriya was the 10th and Bakugo was briefly the 11th user. He choose the name Ash because of his original quirk, and after finishing college, he became All Might's sidekick, after his retirement he went to work with Sir Nighteye, and after his death, with Endeavor, because of Katsuki studying there in hero work studies.

## Quirks

Tenko only has the All for One quirk in outcome 1, so I'm not telling much about it and you all already know what it is capable of, his Decay is also very well known, but if you want to see the quirks, for All for One click here and for Decay click here

* **Ignite:** Endeavor gave Tenko flames like Dabi's, but they were already blue. Tenko kept on praticing with his quirk and managed to even surpass Dabi's flames, giving his blue flames a partially white, not fully because he stopped training with his fire quirk. His flames are powered by his emotions, he managed to not need rage to power up his flames, instead he uses his determination to keep on going.
* **Unnamed Ice Quirk:** Works just like Rei's, his ice is also power his emotions too, he trained more with his ice than with his fire, making his ice be just as difficult as Geten's ice to melt. He can also mash his ice with his decay, making a super move.
* **Icebreak:** Not something he can use always, only when he's really calm he can combinate his unnamed ice quirk and decay, he manages to make a move that he called "Icebreak", he touches a person with his 5 fingers and the person turns into an ice statue and then it breaks completely, killing the person, he can also turn the floor into ice with ice spikes coming out of the floor.

## Oboro Shirakumo

Depending on Tenko's outcome, a different thing can happen to Shirakumo
