Tanya

In a world where 80% of the humans had superhuman abilities, there existed a happy family of a mother and two brothers. They lived normal lives one of them had a Quirk named All for One, which lets him steal Quirks from others. The younger one named Yoichi Shigaraki didn't have a Quirk.

At the moment they were shopping for baby clothes because their mother was pregnant. Their father left them to buy milk after he heard that their mom was pregnant again.

They were both happy about their new family member. However, this happiness didn't last long, because on their way to the shop a Hero fought a Villain and their mother died because of the Hero. The Hero sliced a hole in the stomach of their Mother.

The Mother knew she wouldn't survive this but she had hope for the kid. She looked at All for One and said. "I know you can save her," she vomited blood, "take her out of my stomach and constantly heal her till you are at a hospital *vomits more blood* her... name should be Tan....ya.." she said breathing heavy. At first All for One wanted to take revenge on the Hero but as he saw the squirming of the baby and took it to a hospital where it got medical attention.

As soon as Tanya was taken care of All for One informed his brother who was away to look for toys for the baby.

After that, All for One began a search for his little sister. She stabilized but she didn't get better.

And years later he found one or to be exactly there were two. One was a Quirk that reverses the time of the body before the Injury happened and the second allowed the use of the Quirk to let you control the age of someone and you could add to a maximum of 5 Years permanent.

He needed both because if the body reverse Quirk worked he it would recede his sister to an age where she could not live without being inside a womb so he would alter her body to the same age as it was before.

***Tanya's 9th birthday***

"Big brother Drake (All for One's name) how can you join the military?" A petite, fair-skinned girl with a pretty face. She has slightly inward-tilting bright yellow eyes with thin slits, making them somewhat resemble those of a cat, and her wide mouth is also rather feline, as both her upper and lower canines are more pointed and longer than the rest of her teeth, giving her a vampire-like appearance. Her hair is a pale, dirty ash-blonde and is flowing down her back (basically Himko Toga as a child without messy buns).

Drake nearly spat out his tea and asked. "Why would you want to know that?" Well you know how useful my Quirks are and everything and I want to help the people but I don't want to be a hero or a Villain. So I thought that I will join the military so I can protect the people from outside danger."

At first, Drake didn't want to agree but in the end, he agreed and she joined the military. Now it had two reasons why he let it happen. First, his brother didn't like Tanya because her Quirks were villainous and he was no longer part of the family. So he didn't know where to put her, he didn't want her to grow up I. an orphanage, where she could get abused or worse and he didn't want her to be near him and his Villain work only to be used to threaten him. The second was because she could use her Quirks more often. Her Quirks were:

Transform: Tanya's Quirk grants her the ability to transform into a physical lookalike of another individual, as well as copy their voice. She can only transform into people whose blood she has ingested. The more blood she drinks, the longer she has access to that person's form. She can switch between the appearances of multiple people if she drinks the blood of more than one person. She can even duplicate a person's clothing.

Upon deactivating her Quirk or switching to another disguise, her disguise melts into a gray viscous liquid.

And if she had enough understanding of the Quirk she could even copy the Quirk of the person which blood she drank.

Body-Reset: This Quirk makes her unkillable because her body would simply reset into a state before she even received a would but the scars are left on her body even scratches. The heavier the wound the heavier the scar.

God's Blessing: Wich lets her use energy after praying to God to do different things from floating a Pen to making a normal knife slice through metal like it was air. After long training, she can use the energy without praying to let a pen float. but still has to pray to make a knife sharp enough to cut metal.

"Ok, I can help you if you promise to use the name Tanya Degurechaff from now," Drake said after pondering over the question a long time.

***100 Year's later***

"Ok listen up you fuckers this is the last mission before I have to go on an undercover mission," a female child-like voice shouted at her subordinates. On a pile of boxes stands a child who looks no older than 10. The scene looked almost comically how the nearly 420 men seriously listened to a little girl. But nobody laughed.

Everybody knew who she was, she was a General, no the General. She was only known in the military because the News never talked about wars the only thing news cared about was the Heros so she was not famous only even though she lived more than 100 Year's and was still looking like 10 because that was not a one-time thing through the Quirks.

"Today we cleanse this Country ruled by Villains and take it over for the Fatherland!" The kid shouted again, "Why are you still standing there take your weapons and charge!!!" The whole army saluted and shouted. "Yes, General Degurechaff!"

The Army took their weapons and started their vehicles.

A while later the army arrived at the frontline where the Villains stood against them. The General flew into the sky looked down and made a hand movement like she wanted to scare away some annoying bug and five Green panels lighted one in the middle and the other four around it.

As the Villains saw that they shouted. "Run! Turn around it is Tanya Degurechaff the Devil General." But it was too late for them and a Prayer was heard on the battlefield. "Oh all mighty, please bless this insignificant one to let her purge her enemies of this world and defeat the evil."

The old rifle in Tanya's hand was shining in all colors of the rainbow before she pulled the trigger and a massive boom was heard. As soon as the bullet left the barrel it split into many tiny ones and sprayed on the enemy's army, every time a bullet piece dropped it created a huge explosion.
