As soon as his mouth closed, All For One could only feel pain cursing throughout his body in an instant, as a metal punch connected with his face, with the burning heat being emitted from the palm of the fist also having an impact on the face of All For One, as his body flew back as a recoil from the punch, his mask almost completely shattered by this point. All it took was less than a second-Genos knew despite his current damaged state, his immense speed and reaction-time advantage was still present, and he knew if he kept this up he could very well, despite the odds, have a shot at defeating All For One. All he had to do now was use his speed, know when to close in or incinerate at a distance, and most importantly keep his guard up.

After all, statues can't fight back, right?

All All For One could do at this point was endure the repeated attacks from the cyborg, whose speed was far too great for him to fight back against-the cyborg was getting as fast as he could get, with blows covering over him almost every second, yet his eyes failing to catch any sight of the cyborg completely, the most of which being a blur. The blows hurt-blood was flying in every direction, yet Genos remained unfazed by the sight. The blood was a sign of his attacks working, and he intended the fight to continue this way.

His head ducking down, Genos effortlessly evaded an air blast aimed in his direction, before his left hand outstretched to land a hook on the liver of the villain, before proceeding to repeat his action 4 times, a few cracks coming into existence as All For One felt his ribs being shattered completely, before his fingers shot out black tendrils to try and grab the cyborg again, in order to counterattack. To Genos, dodging his currently pathetic attacks were not an issue. Effortlessly speeding in the other direction, a powerful left hook met successfully with the chest of the villain, whose body completely shattered the debris behind him after a prolonged period of soaring through the air, his mouth letting out a small grunt.

Genos strode over with a certain amount of pride and fury, his palms glowing bright orange. As the flaming orb grew bigger and bigger, ready to fire at any given moment, his eyes displayed intent. Inside his heart, a fury grew, akin to a wildfire. The intent to defeat. The intent to kill.

"Incinerate."

All For One soon found himself struggling for his life, his air cannons operating at their current maximum capacity, combined with his other quirks. Yet he was still struggling immensely-out of all the opponents that he has faced in the past, Genos was on a whole new level. He was evidently superior in nearly all aspects. Speed, firepower, durability. But nearly all aspects. Just nearly.

As Genos's eyes caught the sight of All For One's heavily wounded and burnt body emerging, his fists, on the command of is brain, tightened up, his eyes showing nothing but resolve. Yet All For One, an evil grin still present on his face, stood up, a frighteningly elegant aura surrounding him at every second.

"A hero has a lot of things to protect, don't they-"

His sentence was cut off by an excruciating amount of pain, emitted from the pain receptors from the right side of his stomach, accompanied by blood, flowing like a waterfall scattered throughout the air. It took him a good 5 seconds to realize what had exactly happened here-all thanks to the sound that Genos made while breaking, his right arm blade fully stained red, with blood dripping now and then. All For One's legs could only stumble as he took in what had just happened.

His eyes failed to react to the sheer speed of the slash of the cyborg just now.

"Putting civilians in harm? I won't let you."

As soon as Genos spoke, his hands clapped together, before sending them straight, his arms folding apart to reveal a combined cannon, his eyes locked onto the target. He knew that this attack was enough to defeat him. And he was going to make sure it did.

"SPIRAL INCINERATION CANNON!"

Yet at the second that he was about to fire, his eyes sent his brain an image that immediately halted his process. All he could do was grit his teeth as All For One's right hand tightly grasped the neck of Mt Lady.

Now his attack was wasted. Unable to be used. Yet All For One used this to his advantage, his right hand, on the command of his brain arched and released Mt Lady, with her landing into the arms of Genos, whose reaction time allowed him to catch the full view of All For One accelerating towards him with his right arm now hosting his ultimate combination of his quirks.

All For One had originally wanted to save this for All Might. Yet now he was forced to unleash this, his aim now nothing but to kill the cyborg in front of him. As his monstrous, gigantic punch accelerated towards Genos, his mouth couldn't help but let out a small chuckle.

Yet Genos knew that he can't die just yet. Not with Mt Lady in his hands, still unconscious, and tightly grasped to his chest. Not in hell was he going to let a life, let it be hero or civilian, be lost in his hands. Utilizing his superior reaction time to his advantage, his palm let out an incineration cannon, which despite connecting with the punch, didn't seem to have much effect. Genos caught that, and on the command of his brain, his rocket boosters operated to the maximum, he let out a punch that was instantly able to stop the villain in his tracks, his left hand still tightly grasping the unconscious hero in his hands.

"Impact Recoil!"

As soon as the words were said, Genos could feel the same shock ripple through his body, forcing him to drop to one knee just to support himself and the punch. All For One, his senses catching the sight, laughed manically as Genos's mouth let out a scream. It was like a final battle roar of a last stand, in which the determination was there. He was going to make sure with all his ability that the villain was not going to kill them both. Not on his watch.

Yet the power of the punch was too great for the current Genos, and after a few seconds the cyborg was sent soaring through the air, alongside Mt Lady. Refusing to let go of her, his body acted as a shield for her as his body made heavy contact with the buildings and debris behind him, eventually coming to a stop. Finally releasing Mt Lady, Genos's back was leant against the wall, with his face seriously cracked open, his arms by his side, internally damaged, and electricity splattering constantly. As his eyes caught the sight of All For One turning his back on him, his body getting smaller and smaller as he got further away, Genos's teeth gritted as his arms fumbled to help him get up, eventually kneeling on one knee as his will forced his body to continue.

He knew that he had been through worse. For instance, the fight with Deep Sea King was a clear example. He was beaten to the point of breaking down. If his master was not here, then all the people in the shelter could have been killed. Including himself. But now that his master was not here to help him in any way, he could only rely on himself. Which was why he knew at this moment, he couldn't die, or lose.

His eyes illuminating bright yellow in the face of the night, Genos's feet carried his body upwards, albeit stumbling a bit. The damage was clear to him-his sensors had told him that. Yet it was not enough for him to stop.

He won't allow it.
