Attack

'When are they going to come?' Shiro sat on his couch waiting for the arrival of Kurogiri.

Today was the day that the plan would begin.

As Shiro sat patiently a purple mist expanded inside his apartment.

"Kuro It's time." Kurogiri announced his arrival and was ready. Shiro quickly whipped on a smart black suit that highlighted his muscles, with a black overcoat. One had to fight in style after all.

He then stepped into the mist disappearing.

In the blink of an eyes Shiro was transported to a large open area where many villains were gathered.

Kurogiri expanded massively providing a large gate and everyone stepped inside.

'This should be fun.' A grin raised on his face.

He stepped through and arrived at the Unforeseen Simulation Joint. Its purpose was to train Hero students for disaster rescue, and had it was shaped as a large dome, with many different environments inside of it.

Shiro walked forwards and he noticed a large monstrous looking figure. He hadn't seen a nomu in real life before, but it looked rather disgusting...

The students were at the entrance and pro hero's eraser head, and 13 were present. 13's abilities allow her to conjure a black hole suction effect from her fingertips.

This ability could possibly kill Shiro as not even light could escape it and and sucked into it would be turned to dust...

Eraser head jumped towards the villains and started his combat. He fought well as the villains were mostly weak and brought for a distraction. While he was fighting the students ran to take shelter, but were stopped by a familiar mist, which spread them throughout the area.

Shiro was in an area dubbed 'The Landscape Zone' and a student named Shoto Todoroki fell though the gate. He was one of the recommended students, therefore he hadn't seen Shiro before.

His quirk was extremely powerful and was called 'Half Hot Half Cold' It allowed him to produce flames and ice from each side of his body.

Shoto quickly froze the ground and ice crept up Shiro and the villains surrounding him.

"It's pathetic to lose against a single child."

"Get a hold of yours-"

He stopped his speech as he noticed the ice breaking on an individual that had short black hair and dressed rather smartly.

"Wow. That was refreshing." Shiro enjoyed the gift and awaited Shoto's next move.

"Hmph." Shoto quickly blasted a ball of fire towards Shiro. While Shiro could take the impact and be perfectly ok, his lovely clothes would be ruined in the process.

Shiro dashed slightly to the left and dodged the fire.

"Cool attack. But you missed..." Shiro stood with a cheeky smile that annoyed Shoto. However Shoto wouldn't act on anger. He was in a dangerous situation and this person looked rather strong.

As Shiro and Shoto were having their battle, Katsuki Bakugo was absolutely annihilating villains with his explosion quirk and he was joined by Eijiro Kirishima, who had the quirk hardening.

The other students were all engaging in fights of their own and were taking out many of the weak villains.

*WHISH*

A combined force of fire and ice exploded towards Shiro. The attack consumed a large radius and was approaching him quick.

'Pierce'

Shiro explosively punched outwards, and a gaping hole appeared in the middle of the attack. An oval shockwave followed as it was aimed towards Shoto.

*BANG*

The shockwave hit him and he flew backwards into a rocky wall.

'Huh? I thought that would be harder...'

Shiro looked at the slightly injured Shoto and grew bored. He disappeared from his spot as he wanted to go visit his other classmates.

As he wondered around unnoticed he saw 3 classmates surrounded by a large group. Kyoka Jiro, Momo Yaoyorozu and Denki Kaminari.

They were currently backed up against a large wall and waiting for the villains to attack.

"Guys. I got this one." Shiro moved in front of the villains and told them his intentions.

"Hmm? Move idiot! Or I'll ki-"

The villains face was grabbed, as his face wrapped around Shiro's hand. Painful murmurs sounded and soon cracks were heard.

Shiro had to be a bit violent to show these villains that he was being serious. The villains eyes rolled back as he fell unconscious.

*poof*

He fell to the ground and the others moved backwards looking for some other students...

"S-Shiro!?" Denki was the first to regain his composure after that violent act...

"What are you doing here!? A-and weren't you kicked out?" Denki's thoughts travelled from his brain and out his mouth and Momo and Kyoka stood silent.

Shiro placed his hands in his pockets and looked around. "Well... I am a villain now. And so far it's going pretty well. And as for U.A... Not sure. I might come back if it seems a little more fun."

Shiro had no great ideals at the moment. Of course his one big interest would be going inside simulations. He was even thinking of going into the Baki world again as he never really explored the being named Hanma... But that was only a thought.

"If your a villain now. Then It's our responsibility to stop you." Momo finally spoke with a look of determination. She hadn't gotten familiar with Shiro and therefore, had no qualms about him becoming a villain.

"Your right!" The same look of determination was placed upon Kyoka's face. The three then readied their stances as they prepared for a fight.

Shiro showed a frightening smile and he awaited their attacks. "Come. And try to make this fun..."

The three sprung around him and attacked him from each side.

Momo with her quirk creation, created a long staff which she used to attack Shiro's lower leg.

Kyoka ran towards Shiro and intended to plug him with her quirk earphone jack. Her quirk made her have long, controllable earlobes that work like headphone cables. They were very strong and could even pierce concrete.

Denki charged himself with electricity using his electrification quirk. He then expunged it from his fingertip firing a bot at Shiro.

Three attacks rushed towards him and hit him at the same time. Shiro raised one hand and blocked Kyoka's attack.

*BAANNGG*

The three young hero's jumped backwards as they looked at their foe.

The electricity had impacted Shiro's face, which had now been turned towards the left. As Shiro looked back towards the young hero's they grimaced.

A hole in his cheek had formed showing his gums and his teeth.

"That... Was a good attack!" Shiro didn't think the attack would damage him but clearly he had underestimated these young hero's.

As he stood the wound showed signs of healing. Shiro's eyes flashed silver as he activated something to speed up the process.

'Void State'

"H-he's... Healing!" Momo lost her composure slightly as she saw how fast the wound closed up. "3 seconds..." She also noticed that Kyoka had managed to wound Shiro's hand, poking a hole straight through the middle of it. But...

"It's all... Healed." Denki was very surprised. Healing quirks were very rare in this world and to have one this potent was astonishing.

"Stop thinking. We need to defeat this villain!" Kyoka said. This was a battle and it wasn't a place where one's mind should wonder off...

The three nodded their heads as the prepared another attack.

*WHIFF*

"Hmm? Where is h-" Denki was suddenly grabbed by his leg as Shiro picked him up and threw him at Kyoka.

"AHHHHHHH WATCH OUT!"

*BANG*

He impacted Kyoka's body and the two flew into the wall.

Momo quickly conjured a net gun and fired at Shiro, thinking it would incapacitate him. As she saw it land, she quickly ran towards her fellow classmates, "Listen up! I think I figured out his quirk..."

Shiro quietly watched the ordeal.

"His eyes! When his eyes glow silver he can regenerate fast. He must have a limitation, and we need to figure it out." Momo was quite a smart individual, but how would she decipher that this wasn't actually a quirk? And that Shiro's regeneration was still present even without silver eyes.

As the three continued battling Shiro. Eraser head was fighting against Tomura.

He was currently at a disadvantage as his quirk's effect lasted less with each use. Tomura's quirk was also very powerful as it was able to decay anything he touched with his hand.

Tenya Ida on the other hand was quickly departing to get help. His quirk engine allowed him to produce engine-like protrusions on his calves.

*BANG*

Eraser head was slammed down by the large nomu, cracking the ground. The nomu had one hand on his head and the other slowly crushing his wrist...

*crack*

The nomu twisted eraser head's wrist breaking the bone.

"ARGHHHHHHH" Eraser head let out a pained scream.

"Hmmm? What's going on here?" Shiro had already finished battling Momo, Kyoka and Denki. He didn't injure them much and decided on knocking them out.

Tomura and Kurogiri stood watching eraser head, before they were surprised by Shiro.

"Some guy with engine legs escaped. Probably bringing reinforcements." Shiro seemingly brought out a bar of chocolate, something that he was doing rather frequently lately and nibbled on it.

"Kurogiri is what he said true?" Tomura looked at the purple mist as he asked.

"Yes..."

Tomura started scratching his neck violently. And in a fast motion he threw his hand at Shiro.

Shiro dodged the attack easily and grabbed his outstretched arm. He then quickly jabbed multiple pressure points on his body. Tomura dropped to the ground paralysed.

"Despicable." Shiro was slowly starting to dislike Tomura. "Kuro... He will not attack you again, so undo whatever you have done." Kurogiri knew better than to attack Kuro.

He had seen him fight the three students, and that healing combined with his strength and skills... Deadly.

"He will be back up in a few seconds." Shiro found a rock that was close by and sat down. He was going to wait until it got juicy.

In a water zone of the facility Deku and Tsuyu Asui were watching the ordeal. Another figure named Minoru Mineta would have been present, but Shiro's enrolment into U.A. had changed that.

Tsuyu was a young girl, that had the quirk frog. It's name practically explains it's abilities as it is the amalgamation of Tsuyu's many frog-related abilities.

Deku and Tsuyu had noticed Shiro and were visibly surprised. Deku thought of many things including that Shiro was being an undercover spy, which explained why he only knocked out his fellow classmates.

Deku couldn't fathom the idea of Shiro being a villain as he had a relationship with All Might.

"I have a bad feeling about this, Midoriya." Tsuyu said.

"Oh yeah, before we leave. how about we smash some of his pride as the symbol of peace." Tomura turned towards the two figures that were currently inside the water.

He walked close and crouched down looking at them. In a crazed state Tomura quickly flashed his hand towards Tsuyu's head.

Aizawa raised his head slightly and was about to activate his quirk, stopping the attack.

*WHOOOSH*

The wind picked up and Shiro flashed towards Tomura grabbing his wrist. "How about... No."

"SHIRO!! I knew you weren't a villain!" Deku shouted in excitement. He froze in that moment and thought that his classmate was about to die...

"Shiro?" Tomura looked at the figure holding his arm with an annoyed look.

"You... You were a hero all along!?" Tomura shouted in anger. The plan was being ruined! First someone escaping and now this...

However before he could do anything he was enveloped in a purple mist, which transported him further away from Shiro.

"I never anticipated this, Kuro. Or should I say, Shiro?" Kurogiri looked at Shiro. No expression could be discerned from his face as it was... Mist.

"Well... Your right, but wrong... I'm neither a hero or a villain..." Shiro ominously spoke as everyone watched him.

"I see... A man driven by interest. And interest alone." Kurogiri instantly understood what Shiro was insinuating. Although it was brief, he had talked to Shiro and understood one main thing about him.

*BAAANG*

A loud noise sounded from the entrance as a large puff of smoke expanded.

"I am here!" Opposed to the usual smile.

All Might's face looked angry...
