Void

"Now let's fight"

He assumed the same Darkseid-like pose and took a step forward, to which All Might instinctively took a step backward. The Kid he tried to save moments before felt menacingly evil.

"Please surrender Kid"

All Might made one last effort to persuade the kid.

"Heh, are you kidding me"

Robert could only laugh, he declared to everyone that he was going to kill him.

"Then you leave me no choice"

All Might knew all too well how strong the Nomu was, and he could easily access the power level of someone capable of tearing it in half, he doesn't want to harm a kid but he couldn't afford to go easy on him thus he prepared his punch.

*BOOM*

All Might's punch connected with Robert's punch creating a strong gust of wind and a huge shockwave, the dust-covered All Might's face which had a clear expression of pain over it.

The counter punch thrown by Robert at the last second was too strong that it might have broken a few bones in his arm.

"This kid..."

Nezu's concern was increasing every moment.

"He might just kill him"

Tomura who was infuriated just a moment ago at Robert was now happy that he might get rid of All Might for him.

"What a disappointment" Robert spoke again gaining the attention of all the others "You are injured"

The next words that came from Robert's mouth shocked the entire USJ. Nezu and Izuku were more shocked than anyone since they knew what he was talking about but before they could do anything Robert threw a punch towards All Might's abdomen.

*GUAH*

He spitted some blood and in a puff of smoke he reverted back to his original self, the skinny Toshinori Yagi.

The Majestic figure of All Might crumbled and was kneeling before a new villain. This image was now etched on the minds of every hero and student. Some were shocked looking at their idol while some were angry at the guts of Robert. Some cried in helplessness while some tried to charge head first to save All Might.

"Let us go damnit" Bakugo gritted his teeth as his efforts to blast the wall failed

But before anyone could do anything reckless Cementoss raised a wall to stop them

"It's too dangerous, don't do anything reckless"

While the teachers were trying to control their reckless students Robert picked up the limp body of All Might through his neck and tore apart his upper clothing letting everyone see his horrifying wound.

"Sensei was right..." Tomura murmured

Everyone was horrified, even Bakugo's anger was quelled looking at it.

All Might was now prepared for his inevitable end, the last punch Robert threw was way too strong, probably ten times stronger than Nomu's thus All Might had no energy left to transform back and had accepted his death but what Robert said next shocked him.

"We won't be able to have a proper fight unless it's healed"

"Huh!!"

Everyone couldn't wrap their head around what he said but before they could speculate anything a golden light enveloped All Might, the radiance blinded everyone covering the entire USJ for a good whole minute.

*cough*

The golden radiance died down, and while everyone's vision was returning to normal what they first saw was the muscular All Might standing with his upper body exposed, but with no sign of the wound from before.

"He really healed him" Izuku muttered in surprise

Everyone was just as shocked as him, the scar isn't just healed but it's disappeared as if it never existed.

"YOU IDIOTTT"

Tomura screamed

"You had your chance to kill him but you ended up healing him. I knew you were conspiring with them"

Robert chooses to ignore Tomura and get along with his fight.

"Now then, since you're healed let's continue our fight"

"He is trying to fight All Might in his full power?" Uraraka said what everyone had in mind, it seemed insane for anyone but not Robert, not after seeing the feats he had performed today.

"Why did you heal me?"

"Because I wanted a fair fight"

"Is that so...Very well then"

All Might nodded, knowing he couldn't go easy on him he threw a punch that connected to Robert's face.

"That itches"

He smirked and punched in his abdomen once again which sent him flying towards the podium.

"Principle we must do something"

Midnight said in concern for All Might after seeing the punching power of the new villain.

"I'm afraid we can't do anything"

Principle Nezu had already calculated all the odds, he was ready to sacrifice All Might since he was already weak and train his successor but it all changed when Robert healed him, now he could have an All Might who was as strong as the one in his prime while also having his successor, not to mention if he could get this kid over to his side.

'He is just a kid, no matter how strong he is he must be vulnerable to manipulation...'

Nezu's thinking was interrupted by the constant blasts created by All Might's and Robert's clashing.

"Have Aizawa recovered yet?"

"No sir, his eye is still damaged"

The best option Nezu had was to use Aizawa to negate Robet's quirk and then have All Might subdue him but that is out of the question.

On the other hand, the battle between All Might and Robert grew even more fiercer. Robert threw a punch which All Might blocked with his both arms, which was followed by a round kick from Robert and another straight punch in his stomach which sent him flying above the USJ

As All Might approached the dome above he grabbed one of the iron handles to stop himself from crashing and propelled himself towards Robert below, he was in a much better fighting state than before.

Robert and All Might were about to collide again, Robert redied a punch to throw at All Might's face which All Might simply grabbed and did a back flip getting behind him. All Might grabbed Robert's shoulders the same way he grabbed the Nomu's to stop any movements and he tried to punch him with his other hand but...

Robert threw an elbow attack from behind sending All Might sliding a few steps back, Robert turned around to face All Might but behind him from the dust clouds emerged a familiar pair of red eyes and spiky hair shouting...

"DIE"

"When did he get there"

The teachers were shocked to see one of the students but they were too concerned for All Might to notice this.

Bakugo slammed both of his arms on Robert's face and released the pin with his mouth of his grenade gauntlets covering Robert's face in a huge explosion.

"Got you now you bastard"

Bakugo had a cocky smirk on his face thinking Robert couldn't have gotten out unscathed but his happiness was short-lived, from behind the explosions emerged the unscathed mask of the unknown villain they were trying to fight.

"BASTARD"

Bkaugo was about to charge head first but a layer of ice covered the entire area freezing Robert's body as well, and before Robert could get a chance to free himself various large pieces of debris began to fall over him.

"Phew"

Uraraka who kept the debris afloat finally took a breather but her job wasn't over just yet. Besides her were various metal spears created by Momo that she hovered and threw in the direction of the buried villain. The spear penetrated the debris...

"Kaminari now"

"On it"

Upon Momo's orders, Kaminari released his lightning quirk to the most extreme level which was conducted by the metallic spears.

"Did we get him?" Momo asked but Nezu hurriedly spoke

"Cemmentoss"

Cementos covered the entire thing with his cement, covering the entire USJ central hall, with a villain capable of going against All Might buried underneath.

"Finally it's over" Toru Spoke

Nezu waited patiently for a whole minute before he took a deep breath of relief and spoke.

"You kids did we-"

He couldn't complete his sentence as the earth shook, the podium started shaking and All Might hurriedly grabbed Bakugo from the battlefield to bring him to safety.

Soon after a golden light erupted from the ground, it felt warm to others but it was hot enough to vaporize the cement and all the debris Robert was buried under. The erupted light died down revealing the vaporized ceiling of the USJ. The dome-shaped building had now become a stadium.

And at the entrance of it was the perpetrator behind it all. Robert was walking towards the heroes unscathed, not even a scratch was there on his clothes while All Might who was fighting him was all bloody.

"Let's end this now"

He said and in a blink of an eye he appeared before All Might, grabbing his neck he picked his muscular body up.

"Who are you kid?"

Despite being strangled All Might tried to question the strongest enemy he have ever encountered.

"You can just call me Void"

The sound of his name echoed within the entire battlefield.

Even though All Might now had the same power he held in his prime he was helpless against Robert, he was struggling to get out of his grasp while Izuku threw a punch from behind him.

The punch never connected as the shockwave around him threw him and the other heroes away, and soon enough a burning golden radiance once again wrapped All Might, it was a similar spectacle as before but unlike last time when All Might was actually healed this time was came out after the radiance died was a charred body.

Robert dropped the black burned skeleton leaving everyone in shock and tears. Robert simply flew and disappeared from the sight of everyone present there.
