AU Villain Deku

Ughhh my head...

[Are you awake?]

A voice echoes throughout the dark. damp room. It looks like a torture chamber...

[Where am I?]

[You are in my facility. The silhouette man stands out and walks over to me, he is wearing a black mask with machines hooked up to him.

[Are you surprised? This was done by all might.]

[... Why am I here?]

[You said you'd pay anything to get a quirk. I can give you one, It's a... slightly painful experience.]

[Can you really give me a quirk?]

[Indeed. Usually we would have to modify your body in order to handle a quirk, however this is only the case if you have one already. You should be thankful... that you're quirk less.]

[What do you want in exchange for giving me a quirk... You cant be doing this for free.]

[Ah, how smart. I only have one condition and that is to support my successor, Shigaraki now and in the future as an ally.]

[So in exchange for a quirk, I have to become a villain?]

[A minor trade off, compared to what you'd be receiving I believe.]

[What quirk would I be receiving?]

[Well, that is why we are here. Receiving a quirk can be... mentally taxing, it can drive you insane. Different quirks can be more taxing than others. So consider this... training]

[Do you accept my offer? If you refuse, you can go home. You can live a normal life, as a quirk less.]

[...]

Everything I've had to endure up until now... I wont let it go to waste. I will show everybody what it means to feel useless.

[I agree.]

[Good... Then, lets begin.]

As he steps out of the room he calls somebody else in. It was a small woman. I couldnt see her face. Shee starts taking out an array of tools and different equipment.

[... This will be fun, Its been a while since I've had too.... Break someone fufufufu]

[AAAAAAAAAAAAGGGGGHHH]

[GGGGGGGGGGGGAAAAAAAAAAAAH]

[Let me hear you SCREAM!]

[AGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH]

The.. Pain is overwhelming.... I have to endure... OI need to prove tha..

[AAAAAAAAAAAAAAAAAAAAAAAAAAH]

Blood starts spilling out of every pore of my body, it was as if my sweat itself was turning to blood. She stops for a second as she switchs her tools to a buzz saw. She starts cutting pieces of my flesh...

[GAAAAAAAAAAAAAAAAAH]

She cuts the palm of her hand and drips it into my mouth, slowly my sliced flesh starts to heal.. Was this her quirk? To make me suffer again and again... I cant back down now..

Minutes pass... The pain builds, increasingly more painful than the last. My body is covered with blood, and all I can see is the face of that sadistic woman...

An hour passes... It felt like days, let it stop... what am I even here for? to become a hero? Pfft thats hilarious...

Several hours go by... When will it stop? My flesh is being cut to pieces every few seconds, the woman is starting to look tired... Is she over using her quirk? Do I have to wait until she's exhausted for this to stop?

The woman took a small drink of a weird liquid... She looks much better, what the hell did she drink to stop her quirks side effects, was it blood?

Days? Weeks? It does't matter anymore... I cant even think anymore... I cant feel anymore.. I start hearing a voice in my ear... What was it saying?

[He looks done. He lasted far longer than anybody else, I dont even know how he made it through. Usually people last an hour at most before being put in that state.]

[... Well done. It only means, I made the right choice.]

[Can I have him for my own? His screams are soooo much fun...]

The wrist locks on my arms and legs start to loosen. Is it finally done? am I free?

[Well done, Deku.]

[... It was an... experience..]

[Now, I'm going to pass you on a quirk. Most people wouldn't be able to handle this type of quirk as it corrupts them if its overused. If used to a certain extent, the pain can be worse than what you experience here.]

[That isn't a problem. After a while, I stopped feeling the pain altogether.]

[Hoooh? Well that is interesting...]

[What is the quirk?]

...

[It was a quirk, that I found a few years ago. Someone in a mental asylum suffered the effects from the quirk and went completely insane. I thought it was unique, I took it. I have never used it as I'd probably wouldn't be able to stand the side effects for long. However, I think it's a good quirk for someone like you.]

Finally a quirk for my own... My suffering isn't in vain.

[If you do still feel pain the process of receiving a quirk is extremely painful... So this is a good test whether you're lying or not.]

A black fog surrounded me, it entered into my body. Through my arms, my legs, every piece of my body. Was this supposed to be painful? I looked towards the black masked man.. Although he had a mask on, he was definitely shocked that I couldn't feel anything. His entire being instantly brightened in that moment.

[It is done. You really cant feel anything? You will become somebody extremely dangerous..]

[Hm... What do I call you?]

[My name is... Well, you can call me All for one.]

[Ok... All for one, how do I use this quirk?]

[You have to be able to feel it, as for how you use it... That's up to you.]

...

[So... When do we attack UA?]

[All in due time. We will contact you when we are ready.]

[Hmm. Have they reported that I am missing?]

[No, we have sent people to inform your family that you have taken a temporary break.]

Haha... a break from work for the first few days...

[We have done everything to ensure that you wouldn't be suspicious. As for your designs, we have submitted them already.]

[You guys did all that? Just so that I can help you take down All Might?]

[Not exactly, this is more like a test. To see the capability of Shigaraki.]

[Is that everything? Can I leave now?]

[Hooo, you have an attitude. There's one more thing. This is a mask created with a disguise based quirk. If you wear it, you're appearance will change.]

[That's extremely useful...]

[Indeed, its a rare item. It cant change you're bodies appearance but it can change your hair color and your voice.]

[Thanks for everything..]

[No problem, all you have to remember is our deal.]

[Yes... I will support, Shigaraki Senpai...]

[Good...]

I still feel mentally exhausted... I can still feel pain... however a knife stabbing into me feels like a needle pricking my finger. I guess its both a blessing and a curse.. More importantly, I need to find out how to use my quirk...
