"Shut up, useless Deku!", a younger Katsuki shouted.

"But Kacchan. You shouldn't use your Quirk to harm other people!", Izuku said as he defended a crying kid behind him.

"It's not my fault he's weak. Move away Quirklesss loser or I might beat you up", Katsuki threatened as small sparks exploded on his palm.

Izuku still remembered all of the abuse he received from his "childhood friend". No matter how hard he tried to befriend him, Katsuki would always reject him and hurt him in the process.

Now that he thought about it, society was messed up. Katsuki was a known bully and he had no respect for other individuals. He was always scowling and his pride was the worst. And yet he got into the most prestigious hero school in the country, UA. Why would UA think that Katsuki was a hero material? Izuku didn't understand that. Maybe it was time to test it and see whether he could be a hero.

Izuku walked up to Katsuki and then his clothes transformed into a black suit and his signature helmet masked his face.

Katsuki felt a tap on his shoulder and when he turned around…

"Hey", All for One greeted.

He immediately recognized the man who approached him. Before Katsuki could react, a huge shockwave spread out and he was the only one unaffected. The lights of the mall went out, the stalls' windows shattered, the people were injured, and there were a few flames here and there.

"All… for One…", Katsuki managed to say.

"Hello Kac… Bakugo"

Katsuki was feeling cold. He had the Provisional License to take care of the villain but somehow, he couldn't move a muscle. Was it fear? Was it because he knew that he couldn't hold a candle against the man who killed Endeavor and destroyed an entire school?

"What do you want?", Katsuki asked calmly.

He had to distract him. Anytime soon, the pro heroes would arrive. It was foolish for him to try and fight a powerful villain alone even though he hated to admit it. Katsuki could feel the difference in their power just by being in All for One's presence.

"I saw your performance at the Sports Festival. Quite amusing to see a first placer to not be satisfied with his performance", All for One answered.

"It's because that Half-half bastard held back"

"I see. You wanted to prove yourself right? You want everyone to see that you are a worthy hero"

Katsuki didn't like where the conversation was going. All for One pointed at the fourth floor of the mall. A woman was dangling from the edge of a damaged railing and pretty soon, she would fall.

"Now, hero. Prove to me that you can actually save lives", All for One said and snapped his fingers.

It took a second for Katsuki to react and launch himself into action. The woman was falling and he put all of his effort to go faster in order to catch her. But he didn't reach her. The woman fell with a splat which Katsuki couldn't forget for the rest of his life. He knelt beside the dead woman and All for One teleported beside him.

"Poor woman. A hero failed to save her. You are quite slow for someone who was supposed to be in the fast lane", All for One taunted.

"BASTARD!", Katsuki shouted and released an explosion at him.

However, All for One was unfazed.

"Now you're saying it's my fault? I even gave you a chance and a warning but you wasted it all. Now… Which one of us is at fault now?", he asked.

Katsuki released more explosions and All for One stood as if those explosions were like a breeze to him. He backed away and gritted his teeth. Katsuki knew the difference in their strength but he couldn't just let the villain get away. Not after he caused pain to that Half-half bastard. And not after he messed up society.

All for One stretched his arms and black mist covered Katsuki. The mist then disappeared and Katsuki was surprised to see himself in his hero costume.

"If you're planning on fighting me, I should at least allow you to make it entertaining", All for One said.

Katsuki growled and explosions sparked in his hands. All he wanted is to tear the villain's mask and see his surprised face. After that, he would beat him senseless. That was what he would get by messing with him.

He launched himself at All for One and attempted to kick but All for One blocked it. Katsuki did a right swing but the villain blocked it again. The hero released explosions at his enemy but the villain wasn't even damaged.

"Tch. Stun Grenade!", a flash of light engulfed the area and when it disappeared, Katsuki was high above the ground.

Katsuki propelled himself in a circular motion and created a tornado. He crashed to the ground and caused a major explosion. Smoke covered the area and Katsuki panted.

"Did that get him?", Katsuki asked.

Vines grew from the ground and wrapped around his legs.

Of course not! This guy fucking defeated Endeavor! He wouldn't die that easily!, Katsuki scolded himself and destroyed the vines.

"Come at me Bakugo Katsuki. I'll take the pleasure of crushing you down after you try your best in defeating me", All for One said.

Katsuki released the pin in his gauntlet and a large-scale explosion headed towards All for One.

All for One stood at the same spot despite receiving a huge explosion.

No effect huh?, Katsuki asked in his head.

"Is that all you've got?", All for One asked.

Cold sweat dripped down Katsuki's face. He couldn't believe that he was actually feeling fear. Most of the time, he hid his fear by being confident but this time, he felt true fear. He couldn't defeat his opponent. There was no way he could win. Katsuki clenched his fist. If he was going down, he'd go down trying.

He launched himself to the air with some explosions and swiftly approached All for One. Katsuki punched, kicked, released explosions, and even released the pin of his gauntlet at point-blank.

But All for One wasn't even hurt.

"Is that all?", he asked.

Katsuki panted. He was running out of ideas and breath. The one he was facing seemed to be invincible. No matter how hard he tried, his attacks wouldn't reach.

"Very well. It's my turn", All for One said and disappeared in front of Katsuki's eyes.

The young hero felt a strong blow on his gut when the villain instantly appeared in front of him. He was launched all the way into the air and when he was about to crash, All for One teleported behind him and kicked him to the ground. But that wasn't enough. All for One fired beams of energy at Katsuki which became stronger after each shot.

All for One teleported to where Katsuki landed.

"Are you done? You know, that's nothing compared to the pain you dealt to me", Izuku said.

The fuck is he talking about?, Katsuki thought.

Katsuki was actually faking that he fainted. All he had to do was wait for an opening and launch an attack on All for One.

"The pain you caused me and the humiliation you gave me made me wonder why I bothered to befriend you. Maybe because I still hoped that things would return to the way things were. When you weren't an egotistical bastard", Izuku told the "unconscious" Katsuki.

All for One turned his back and Katsuki saw his chance. He used an explosion to launch himself upwards. All for One was caught off guard and when he turned around, Katsuki released the strongest explosion he ever made. His shoulders almost cracked because of the pain but he gritted his teeth.

The smoke cleared and he saw that All for One was on one knee. Katsuki noticed that his mask was cracked and a part of it broke off, revealing a green eye which was filled with hatred.

Katsuki felt a familiar feeling in that eye. It was as if he saw that eye before. Did he meet All for One before? From what All for One said, he could think they met at some point. But he would definitely remember someone as powerful as him.

"That's amazing! You're the first one to catch me off-guard. Maybe it's because you're you that's why I became relaxed. I guess I'm still a softie despite all of the things I've done", Izuku praised Katsuki.

"I don't fucking understand you", Katsuki said.

"I know you don't… But still… you broke my mask… It's just right if I broke something of the same value from you right?", All for One asked.

Katsuki felt a strong grip on his body. He tried moving but it was in vain.

"Maybe I should break some of your bones… like the scapula", All for One snapped and Katsuki felt intense pain as he felt something snap inside him.

"Then… the clavicle, humerus, radius, ulna, scaphoid, lunate, triquetrum, pisiform, hamate, capitate, trapezoid, trapezium, metacarpals, proximal phalanges, distal phalanges, ilium, ischium, pubis, femur, patella, tibia, fibula, talus, calcaneus, navicular, medial cuneiform, middle cuneiform, lateral cuneiform, cuboid, metatarsal, proximal phalanges and distal phalanges", All for One continued snapping and for each snap, Katsuki screamed in pain as his bones broke.

"You… I'll kill you… I'll fucking kill you!", Katsuki threatened.

"Let's see you try that next time", All for One replied and touched his head.

Pain surged through Katsuki and knocked him out. All for One laid him to the ground.

"Let's see how you'll live the Quirkless life, Kacchan", Izuku said and teleported away.
