At the time Inazuma went to deal with Chisaki, things were going the same way as canon for the others, albeit with a bit of difference, as due to the influence Inazuma had in the world, the powers of both allies and enemies had risen by a level.
The acquisition of the villains' hideout in the bar was easily done by All Might, but just as the villains tried to escape, Inazuma had already taken out Garaki's teleporting clone, which All For One was planning to use to reduce the stress he was feeling while using it himself on multiple targets.
The run-in with Inazuma and the subsequent battle with All Might had damaged him more intensely than he had hoped, and even after all these years he had spent collecting quirks at a rapid pace, he was unable to become stronger in any way after some time. Garaki then was able to find out that All For One's trauma from whatever he saw had created a psychological block in him that had manifested in his quirk factors.
He was unable to take in more than a dozen quirks, and adding more would only result in weakening him further. Plus, since he had taken in hundreds of minor and major quirks for recovery, he had actually harmed his body, as even his natural healing was affected by the overloading of quirks in his body.
This led to even more damage and limitations to his own body. But since most of All For One's organization functioned on the quirks he had stolen, he and Garaki made certain quirk-containing Nomus, which took the strain of using multiple quirks away from All For One, although it took away a lot of stamina and caused him significant physical and mental strain when he used it. All For One then decided to use these nomus to handle all the quirks except for the set of quirks he was building to counter Inazuma.
So, seeing that the teleportation-containing quirk Nomu was missing, All For One began to get a bad feeling that Garaki had been captured in the same way his vessel was being captured by All Might right now. But at this moment, he had no choice—since the Nomu was not there to take the strain of the extra teleportation quirk, he had to execute the backup plan.
Immediately, as the heroes captured the villains, an explosion spread out with Kurogiri at the center point, knocking out all the heroes and villains alike.
'Good thing it still works,' All For One thought as he pressed another button. He had made sure Kurogiri was fitted with a lot of cybernetics when he was created. The unexpected danger he had faced with Inazuma had made him even more cautious about letting everything go without a backup plan.
Using the body of Aizawa's old companion as a cornerstone for his plans and designing the teleportation quirk for him worked because of two key factors. First, the quirk his body had already possessed, when combined with another, was what created the shadow body as well as the teleportation quirk. Plus, if Kurogiri was captured, analyzing his DNA would have been more than enough for the heroes to find out who he was, making some of their most effective members reluctant to make the hard choice when dealing with Kurogiri.
This was the same tactic he had planned when he targeted Tomura, as his original identity would deter both All Might and Gran Torino, along with a few others, when they dealt with him.
"Emotions—many say they make a person strong, but they never speak about how easy it becomes to manipulate a person using them. Though even I can't deny it, isn't that right, little brother?" All For One spoke to himself as he took out a preserved arm from storage that looked similar to the ones Shigaraki wore.
Every move he made was calculated in some way or another—even the arms that were said to be his family's given to Tomura were fake, as it was a way of instilling an obsession with his brother's arm into him.
All For One watched as Kurogiri knocked back all the heroes while the bombs in the surrounding buildings went off. He had made sure that the bombs did not directly target people but instead left more of them alive, so the heroes would spend more time saving lives, which in turn would give more time for his pawns to escape.
He watched as the cybernetics in Kurogiri activated his quirk and made the villains appear near his current hideout.
CRASH!!!
The startling sound made All For One turn backward, even though that gesture was not needed for him to use his quirk to see in that direction.
'Damn it, I was distracted by their attack on the other side—I didn't even see them coming here. It must have been that Nezu who did it,' All For One thought as he pressed the button to activate Kurogiri again.
But the red letters that appeared on the screen stopped him.
"Damn it, his battery is low!" All For One cursed as red and black solid tentacles emerged from his hand. "Looks like it's time I come out of the darkness."
He then turned to the file named Blood Lightning that was on the nearby table and sneered.
"Even if I have to come out, with the way All Might is right now and the only person who can stop me having vanished from this world, nothing can ever stop me in this world," All For One muttered as he prepared himself to face the world.
At the same time, with the heroes—
"All Might, get the hell to the other hideout and deal with them! We will handle the civilian situation!" Torino screamed at All Might, seeing the situation get out of hand within seconds. He had always known that All For One used underhanded methods, but this time, he had crossed a few lines with the number of people he had endangered.
"Got it!" All Might replied furiously, clenching his teeth.
