Streams of gore flew by as the Saiyan made his way towards the epicenter of the conglomerate of creatures that seemed to spew from nowhere. Resembling a less muscular version of that Nomu creature from the USJ, Black noted that they only had a fraction of its strength. As more organs and blood piled up on his body, Black's face would distort to more hideous levels of rage. To force a god's hand to be dirtied like this was most definitely a sin.

Noticing the surroundings, many people who were once waiting in the office ran disorderly with no sense of calm. The police officers nearby clearly tried to settle the pandemonium down all to no avail as more of the creatures ran amok the crowd of civilians.

"Where are the heroes around here?" a voice of one officer said, desperately shooting at the gray crowd of creatures.

"The whole block is swarmed with them!" another replied. "We're gonna have to hold our front for now!"

Heh, this actually is getting me quite ecstatic, Black thought as he massacred three of these creatures with his fingers. The sense of rush felt the same as his villain hunt with Aizawa during the USJ Incident.

Still, as easy to slay as the creatures were, the numbers increased to an absolute exorbitant amount. Of course, destroying the entire city would immediately get rid of these creatures but Black decided against doing so. Still in the presence of many bystanders, he realized that it would be quite difficult to explain how and why a city was vaporized. In the midst of considering his options, something in his hand suddenly moved.

"What the-" Black exclaimed as the head in his hand jerked around violently.

The head made a sporadic motion, loosening the Saiyan's grip and dropped onto the floor. Once on the ground, the creature grew several pairs of limbs, looking like some generic regeneration power to Black. After it regrew its body, the creature made a horrifying shriek, stunning the few people still left in the building.

Still, the Saiyan was unaffected, having experience with power ups significantly louder than this. Just as he thought he learned all he could about the creatures, the one in front of him jerked violently again.

"More tricks?" the Saiyan wondered, formulating new calculations on exterminating the monstrosities.

The creature made a similar sporadic motion, this time, splitting apart into identical copies of the creature, unleashing a stream of green goop upon the office. If the room wasn't stained before from the blood, it certainly was now. Black's eyes looked on with even more fiery determination.

This sort of 'cloning,' huh, the Saiyan thought. This regeneration doesn't even compare to that of Zamasu's though. They're still quite easy to squash apart from this healing factor. I think I know just the trick.

Looking around at his surroundings, Black saw that all of the bystanders were on the floor, collapsed. The exit door was glued shut with the regeneration goop, which trapped everyone in the office. Noticing the hole that was made from the first wave of creatures rushing in, Black blasted at it, making it even larger.

"What the hell are you doing?" one of the bystanders asked, confused at why the one person still standing was making even more damage to the surroundings.

"My goals are far beyond your sense of comprehension, mor-uh-human," Black responded, almost forgetting his newfound appreciation for mortalkind. "I will keep you all safe."

The man just watched bewildered, still pinned down. The Saiyan then powered up, preparing his more refined assault against these creatures. Black then swung his arm, unleashing a wave of energy that pushed back all the creatures and their bits high in the air outside. Once he locked them down, he snapped his fingers, completely vaporizing them in a cloudy explosion. Sensing the energy around him, although the office situation seemed to look much better, on the sidewalks, it was still a warzone.

Riot squads shot at the creatures, which did nothing against the rapid cloning of them. For each wave that was put down, three more would somehow appear again, much to their confusion. The few heroes dispatched nearby did not fare much better, with some literally getting dragged by all of their limbs. No one seemed to notice the little progress that was actually made because of the Saiyan.

Regardless, there was no time to rest in this crisis. Black ran out of the office from the hole he made, towards the riot squad nearby. He was able to push another group of creatures back with a flick of his wrist.

"You shouldn't be here!" one of the squad members yelled at Black, still trying to fight the creatures off.

"Well, have you made any progress?" Black rhetorically asked.

"No time to argue," another member said. "I'd tell you to back off if it were any normal civilian but not many people can just fend off things like these with just their bare hands. You think you got a clue on beating these?"

"I know exactly what to do," Black replied, much to the shock of the initial officer. "The creatures on their own are extremely mediocre combattants but they are able to regenerate and this cloning ability. These clones seem to carry over all of the originals' physical traits and abilities perfectly so our main course of action is to vaporize them completely, with no cell left behind."

"How the hell are you gonna do that?" another officer asked Black, still fighting off whatever hordes he was seeing.

"In the state we are now, we are extremely dispersed," the Saiyan answered, feeling excitement at explaining his thought processes. "Rather than attacking them as we are now, we need to group all of the creatures in one spot, such as that park 10 blocks away from us. Then I'll launch them up in the air and we can disintegrate them easily."

"Who put this guy in charge?" the first officer asked, in utter disbelief at what he was hearing. "We're really gonna use a plan some civilian just thought of from his ass?"

"Well, we really have made no progress here," the second officer from before commented. "With the state of things now, we really have nothing to lose."

"Fine, let's send a message to all neighboring squadrons first," the first officer replied. In his walkie-talkie, he informed everyone of the plan. Now that everyone has universally agreed on the strategy, Black powered up even more.

"KAIOKEN TIMES 20!" Black roared.

A stream of red light flashed from the Saiyan, creating a small earthquake. Almost everything near him was knocked back, including all of the surrounding creatures. He most certainly did not need to use any form of Kaioken here but this was a golden opportunity to test his power after everything that happened.

"Get them to the park!" a squad member yelled, pretending that a random red explosion did not happen before him.

Black and the riot squad quickly made their way towards the park, capturing all of the creatures nearby. Other groups of squads and heroes made their way over as well, many of whom seemed to barely be in running condition.

"I sure hope you know the plan for this…" a member in Black's riot squad said.

"Huge crowd but it looks like all of them," the Saiyan remarked. "These heroes and officers seemed to have lured them over because they were being pushed, rather than being the pushers. Tell them to stand out of my way."

The officer gulped and ordered everyone to keep a distance of 100 feet.

Black, still in Kaioken, punched the ground, sending a shock wave so powerful that all of the creatures were launched into the air. Even at a 100 foot distance, the nearby heroes and riot squad were knocked away from their feet.

"The hell?" someone asked, surprised that someone was capable of such strength.

With all the creatures having yet to reach terminal velocity in their trajectory, Black clasped his hands together, readying a stance.

"KamehameHA!"

In a flash of dark purple light, the creatures who were initially in its path disintegrated immediately, with their fellow monsters disintegrated soon after as Black adjusted the angle of the Kamehameha. Sensing the energy around, Black stopped firing when there were none of these creatures left.

"H-Holy hell," a hero with a cape and visor said. "This guy actually did it!"

Black looked around, seeing everyone's face. The reaction they gave was similar to that of being saved by All Might. Before he could get any praise, he heard a loud scream.

"HELP!"

Black, using instant transmission locked onto the person in distress. It was none other than the lobster receptionist lady herself. Hanging by a thread on top of a skyscraper, the one creature who was still alive climbed the building, with a grasshopper man following.

"Goku!" the man exclaimed. "Help me out here!"

Goku Black, flying in the air, cringed at Jiro's struggle against this one creature. In a split second, Black had the lady in his arms with the creature in his hands.

"I'll be sure to dispose of -" Black said. "Huh?"

Black goo emerged from the air, engulfing the creature into nothingness. The Saiyan stared at the air where the creature was for a moment before looking at his other hand. Using instant transmission, he went back onto the ground with Jiro Hotta climbing down from the building.

"Nice work, Goku!" Jiro said. "That lightshow back there was also your doing, huh?"

"Thank you, sir," the lobster lady said, this time showing genuine signs of appreciation. "After this whole mess is settled, I'll help you out with your other forms."

"Wow, thanks!" Black said, surprised that he was delivered such help. He remembered reading about government offices from the internet, a process that proved to somehow feel even more cumbersome than using a Time Ring.

"That's really weird though," Jiro said, turning back into his human form. "I wasn't able to really wound them but I was able to knock one or two of them out. The things were gone with that black goo too!"

"That seems troubling," Black replied. "But we're gonna leave that to the heroes for later because now…"

A full medical squad showed up on scene as well as an army of police cars. The surroundings were given a vigorous inspection before being deemed safe. As Black received praise from riot squad members and local heroes, he felt that very same excitement he had in the USJ.

This hero thing actually seems more fun than I gave it credit for, Black thought. Wonder what Aizawa would say when I gotta assess that Sports Tournament or whatever in a few days. Though, that black slime was weird.

As Black smiled, feeling more at ease with the chance he gave mortals, the black goo warped the few creatures that survived back to their original lab, where they were greeted with a massive electric shock, rendering them powerless.

"A failure, huh," the doctor lamented. "This is the second plan in a row to not go as we wanted."

"It went exactly as I wanted," All For One replied with a devilish grin. "These 'pseudo-nomus' were always supposed to be disposable. The idea was for that 'Mitosis' quirk we invented from Super Regeneration and Double quirks from some of Jin Bubaigawara's hair samples to create a power that would allow these experiments to overwhelm with sheer numbers alone. Of course, none of the damage done will last long at all but I like the results I see."

"But what about the battle data?" the doctor asked. "And you could benefit quite greatly if you had this quirk yourself."

"Good question and a generous offer," the villain replied. "Fortunately, the experimental Mitosis quirk was not all I added to them. I included a 'Banshee' quirk as well as a 'Trace' quirk into the mix as well, for more offensive power and to track them down more easily. While having real copies of myself would turn the tides for my favor, I would prefer being the only version of me in charge."

"So what data did you observe from it?" the doctor asked, still in awe of his master after a century of servitude.

"That Goku," the villain explained. "He's truly the real deal, alright. This was a predicament that I believe All Might prior to our encounter could have solved in three hours. Goku did it in an hour and a half. Judging from how few of our 'pseudo-nomus' returned, I believe he found a way to completely destroy most of them, a feat that even I would be unsure how to do with all of my quirks. Had he known about the powers beforehand, he might have defeated them in mere minutes, even if the horde stretched from UA to Naruhata."

"But how do you plan on getting his quirk?" the doctor questioned, still perplexed that such a 'Goku' character could exist. "One For All was already such a difficult power to even touch, how do you expect to steal Goku's?"

"I have plans that span for lifetimes," All For One replied. "I think the takeaway from this is that you should continue to experiment more on Bubaigawara's Double. The small 'Moca' Nomu you have should suffice for that, I believe. Someone like Bubaigawara would be useful to Tomura's arsenal. Speaking of which…"

All For One reached for his tablet, phoning a call.

"Hello?" a deep, distorted voice answered.

"Kurogiri," All For One replied. "Remind Tomura to keep an eye out for the UA Sports Festival in a few days. It'll be a good learning experience for him."

"I'll do my best," Kurogiri said. "He's too occupied with his games, however."

"Well, the important thing is that you do your best," All For One said in mocking-encouragement. After hanging up, the villain read the news.

"Hero Killer Stain Claims Another Life," he read outloud. "Well, I'll be damned." The demon lord laughed at the press's interpretation of a psychotic murderer, for that was all child's play.

Author's Note: And Chapter 12! I took a break for a bit so hopefully the end of my near daily cycle wasn't too bad for y'all! Also got some people laughing about Tsukauchi getting to the bottom of Goku in chapter 9 quote so idk, Goku Black x Detective Tsukauchi perhaps? Anyhow, thanks for reading!
