A Quirk Through Time/Villain Swap AU

The Knife's Edge

It's been ten years since the day All for One took him in, the memories of anything before All for One were fragmented to the point Izuku couldn't even remember why he liked heroes. A knife flew across the bar striking a picture of All Might in the head. A young green-haired boy with a white shirt and black vest was leaning against the counter. Behind the counter was a man with a suit and a purple smoke surrounding him. He quietly stood there as Izuku began to talk with All for One.

"You sure about this?" Izuku asked as he threw a second knife hitting All Might's eye.

"We created a Nomu that can fight All Might," All for One stated from a TV screen. The screen only had the words sound only on it.

Izuku never really understood how time travel quirks work no matter how many times All for One explained it to him. What he did understand was his sensei would be captured in the future and it would be unpreventable. That's why he gave Izuku All for One but wasn't allowed to use it without permission.

"You're going to gather a bunch of low-rank villains to assault UA, a place that has many Pro-Heroes and upcoming heroes. Even with the Nomu and myself, I don't see any chance of victory without knowledge on the student's quirks. If you allow me to use a basic quirk I could infiltrate UA's hero course, its entrance exams are tomorrow."

"Victory isn't the goal here Izuku, you must think bigger."

"I would rather have everything planned out so when I reach All Might," Izuku walks to the picture pulling out a third dagger and stabbing it in All Might's other eye. "All that awaits him will be death," Midoriya smiled sadistically.

All for One's multiple quirks allowed him to retain some memories of how things were before the time travel incident. Shigaraki, Izuku, and the battle in which he would lose were all he could remember.

"Have you decided what you will do once All Might is dead?"

Midoriya pulled out the knives before sitting on a barstool, he started tossing a knife up in the air and catching it.

"Whenever we have this conversation you always ask that and my answer is the same, I don't know. I guess I find it hard to imagine myself as a leader like you Sensei."

"You still have plenty of room to grow Izuku, I'm sure you will be great." As the conversation went nowhere again, All for One couldn't help but think of the differences between Shigaraki and Izuku.

Having raised them both to spite All Might, he couldn't help but feel fond of them. They both desired destruction and the death of All Might. Shigaraki grew up with a childish mindset, but Izuku grew up with bipolar symptoms. Izuku's mind would swap from thoughtful planning to rash action, probably the result of his past trauma.

The next day only the bartender named Kurogiri was there with Izuku nowhere to be seen.

"Where is Izuku?" All for One asked.

"Um he left a note," Kurogiri said grabbing the note Izuku had left. It was stuck on a knife impaled into All Might's perfect smile. "It says that he's going to infiltrate UA."

All for One remained quiet for a few moments pondering Izuku's decision. "It may be fate he goes to UA, we can only see how it plays out."

On the way to the school, Izuku remained in the alleys. He needed the proper enrollment papers to attend and since being with All for One he didn't have any of them. To his luck, he saw someone dashing through the alleys taking a short cut.

"Excuse me!"The kid yelled as he tried to run past Izuku. Izuku only smiled at the kid and moved a bit to the side pretending to let the kid pass. When the kid ran past Izuku the kid suddenly fell to the ground with their neck spilling blood, Izuku had cut through the entire right side of the neck with one swift motion. Using a red handkerchief he kept in his breast pocket he cleans the knife and beings to rummage through the dead kid's things.

"Ah, enrollment papers, ID, and everything else I will need," Izuku smiled and activated one of the quirks All for One bestowed upon him. The documents began to change-making his own false identity. Izuku decided to enroll with a heat quirk which would enable him to keep the knives on his person.

"Now what to do with you," Izuku stood over the body looking down, he searched for the kid's wallet before throwing it into a giant trash bin "Making it seem like a minor theft should lead the cops around. I better throw these gloves away later," Izuku's journey to UA proceeded smoothly, and it wasn't until he passed the gate that things went wrong.

"Deku?" A voice called, standing behind Izuku was a blonde spiky-haired kid, a childhood friend named Bakugo Katsuki.

"I think you have me confused for someone else, I've never heard the name Deku before," Izuku said turning around to face the boy.

"but you are Midoriya Izuku right?" Bakugo asked completely surprised to see the green-haired kid. "Where the hell have you been all these years, and how the hell are you here your quirkless?"

"I don't know how you know my name but I don't have time to deal with your nonsense, I have a test to pass," Izuku said turning away from Bakugo.

"Don't write me off bastard!" Bakugo yelled grabbing Izuku's shoulder.

"Don't touch me!" Izuku screamed back as he grabbed Bakugo's arm. Izuku activated his heat quick making the skin on Bakugo's arm burn a little "I ain't quirkless so I can't be the person you think I am, now back off!"

As Izuku storms off Bakugo holds his arm where the burn marks are with a confused face.

Deku continued on handing in the enrollment papers to the teacher at the door. He had blonde hair and a speaker around his neck, Izuku recognized the hero as Present Mic who looked over the papers curiously.

Nothing but false information was on the sheet, and it matched the government's records. All for One had inside help when changing the official records. Everything but Izuku's quirk had been altered, but since he was quirkless and the paper said he had a heat quirk a problem arose.

"Can I see your quirk?" The blonde asked.

Pulling out a knife slowly Izuku activated his heat quirk, the blade turned bright red as the teacher could feel the heat coming off from it despite not being near the knife.

"Ok, you can put the knife away,"

Izuku nods as he turns off his quirk letting the knife cool. Carrying a knife wasn't that dangerous since most quirks could be classified as more dangerous weapons.

"Why weren't your records updated when you developed your quirk?"

"It's been a tough time after my parent's death. I will get it changed after the test, promise." Izuku said forcing a child-like smile.

"Alright, go do your best kid," Present Mic handed Izuku a number and let him pass.

Once Izuku was out of sight he began rubbing his jaw. "Those pure-hearted smiles hurt my cheeks," he grumbled.

The first part of the test seemed straightforward but due to his lack of schooling, some of the questions proved annoying. It didn't help that he felt like some dumb blonde spiky-haired kid was staring at him the entire time.

Finally, it was time for the practical part. The objective was simple, destroy robots. The seminar beforehand was a simple explanation of points with one robot oddly being worth zero points. Zero or a hundred didn't matter to Izuku if it got in his way he would destroy it.

The doors slowly opened and the practical exam began.
