The succession of events was practically instantaneous. A blow that bridged the distance between Allen and the portal, which was the size of a tennis court, in an instant. A shock wave that destroyed every building, an impact with the strength of a Superman after sunbathing.
The clouds, hit by the force of that impact, scattered.
"I see..."
Allen's words seemed to slow everything that happened. No, it was definitely slowing down, as if the world was caught in a black hole, all that destruction becoming slower with every nanosecond that passed until it was completely still, and then, in a bizarre way, it started to rewind, as if the cause and effect of this event were reversed. All of this until it reached the beginning, reflected in Allen's eyes.
"This was unexpected..." said Allen with a half-smile after seeing the future.
Allen doesn't seek to be a hero. However, accepting the darkness in his soul, accepting that he is not a perfect man and that his "Void" is part of him, does not mean he will become like it because,, despite everything, the albino Allen is still there.
So, feeling a bad premonition due to his spider-sense, Allen forced his clairvoyance to activate with The Absolute and was able to see everything that would happen seconds later.
[Allen...]
"Yes... I should thank the spider; it prevented a massacre..."
With an amused but alert look, Allen frowned, and unlike before, he wasn't taken by surprise. He focused on who would step through that portal.
*Footsteps*
A man stepped out of the portal. Without giving him any time Allen made his move. His eyes narrowed, and this visitor was seized by chains formed by Clown Crown.
Allen scoffed as he held the end of the chain with one hand, "Easy, cowboy. This ain't your first rodeo… or is it?"
The man tried to free himself but struggled; still, he could not move.
Allen's eyes widened slightly in surprise at the sight of the man's face, "Heh, I should have known. There was a possibility, but due to the canon, I wasn't considered..."
Angstrom's portal started to disappear, and everyone saw a middle-aged man with black hair and eyes, some gray hair, and some wrinkles from maturity, wearing Viltrumite attire, but more dignified, with red and black, as well as a cloak worthy of a king. His body, once a lean figure, was now as robust as that of an adult Viltrumite.
Allen's smile widened, "Five hundred years later... that ruler of the Viltrumites still held his place as the most powerful Viltrumite in history... Emperor Markus Grayson I of the Viltrumite Empire and Emperor of the Universe."
A Mark Grayson over five hundred years old looked at Allen, confused—no, now he was Emperor Markus.
Allen smiled with a hint of mockery, as his relationship with Mark had always been like this, "You've become arrogant, kid."
...
(Grayson House)
Angstrom Levy sighed with disgust, "It took me a while to find him, I had to visit more than two thousand different universes, and in some, I was in danger of dying. But it was necessary to find a Mark Grayson in a dimension where time passed much faster... luckily, this one had a special grudge against humanity, and when he learned he could destroy this world again, he was more than happy..."
"What are you talking about, you maniac?" Debbie grabbed a kitchen knife and stood in front of Olga and Oliver.
"I was just talking to myself... I could leave this dimension and let that monster destroy Invincible, but it wouldn't satisfy me, so Debbie, start calling him, and I won't hurt you..."
To understand what just happened, a few points need to be clarified:
1 – Angstrom Levy has access to countless parallel and different universes.
2 – Angstrom Levy has proven that he has no problem crossing as many universes as he wants, and this does not generate an incapacitating physical or mental burden.
3 – It has been confirmed by the Flaxians and Angstrom himself that there are different universes and dimensions where time can pass either slower or faster.
4 – Angstrom stated that in most universes, Invincible takes an evil path.
So, if we combine all the points above, we can deduce that if Angstrom Levy, who was so desperate for revenge in the canon story that he only searched a few hundred universes, had searched through those infinite universes, he would have found one where the previous points came together, making it possible for a five-hundred-year-old evil Mark Grayson to exist.
It's worth noting that in the comic book storyline, Mark becomes Emperor and, five hundred years later, he still is, and he is so powerful that he can easily defeat Allen, the alien, also an Emperor.
...
(Downtown Chicago)
Allen squinted. He had considered this at some point. If in universe 1, after five hundred years, Mark is the Emperor of the Universe, whose name and rule bring peace to all, what happened in those other universes where Mark is evil?
Not from the eighteen evil Invincibles from the Invincible Wars, but from the many more that Angstrom Levy never recruited, some had to have become Emperors. But unlike the good Invincible... they turned into Tyrants, or even worse...
"What a lamentable world..."
Allen remembered that this version of Mark was supposed to have a kind smile and a look of a man with integrity. But this one had a gaze so devoid of human emotions that it seemed like an abomination with human skin; the smell of blood on his body and the sheer amount of death surrounding him made many shudder just imagining what he did to his world in the past.
[Emperor Markus Grayson I +500 – good version]

...
Superman – His eyes... they're so cold... so empty... so dark. I can only offer my condolences to the universe that had the misfortune of having that Invincible.
Rick – And this is why multiverses of the same world suck Burp
The Emperor – Emperor of the Universe... this had to happen. Allen couldn't leave that world without stealing that title or defeating whoever held it.
MJ – Tsk, a stupid protagonist with the script on his side, damn it, Allen, kick his ass!
Aphrodite – Darling, don't let him intimidate you. Show him who the real Emperor is here❤️~
...
Emperor Markus looked at the chains that bound him, but soon he ignored them and fixed his gaze on the sky.
"A familiar scent... a sky I can recognize... even after five hundred years and ten thousand worlds, I still find a unique world..."
"Oh, that makes it sound like Earth doesn't exist in your universe, kid."
Allen's mocking tone didn't seem to bother Markus, who, for the first time, focused his gaze on his opponent. The man's eyes analyzed Allen, and even after five hundred years, his memory remained intact.
"This is strange. I expected to see old acquaintances—maybe Eve, Rex, Cecil, or Robot... but you? Who are you?"
Allen disappeared, making Markus' gaze drop, only to see him about to strike.
"...!"
"Didn't Debbie and Nolan teach you to say your name before asking others?"
Allen punched Markus in the chin, sending him into space and leaving behind a shockwave that traveled across the Earth.
...
(Grayson House)
Mark had received a call from his mother and quickly returned home. He entered through the window without hesitation, only to see Angstrom smiling, as he grabbed Debbie by the neck while she was holding Oliver in her arms.
Olga, on the other hand, was slammed against the wall with blood oozing from her head.
"Mom! What are you doing to her?!"
"Oh, calm down, nothing yet, but I can't guarantee I won't if you try anything," Angstrom Levy said, happy to see Invincible clench his fists. "You can't kill me before I break her neck…"
Mark knew it was true, but nothing assured him that this guy wouldn't try something worse if he stopped fighting.
*Shaking*
"What?"
The entire house shook, surprising both Debbie and Mark. However, Angstrom, far from being surprised, looked very calm.
"Seems like it's started…"
"Damn, fine!" Invincible raised his hands. "Who are you and what do you want?"
Angstrom grinned maliciously. "Oh come on, don't you remember me?"
"I've never met anyone like you…"
"Of course, that was before you turned me into a monster!" Angstrom released Debbie and stepped forward. "Look at me closely, Mark Grayson!"
Angstrom's face resurfaced in Invincible's memories as he tried to forget that day.
"You... you're that guy!"
Angstrom lost his composure, and his face turned to pure anger, his eyes fixed on Mark full of disgust.
"THAT GUY?! THAT'S HOW YOU REMEMBER ME?! I'M NOT THAT GUY, I'M ANGSTROM LEVY!!"
Angstrom raised his hand and created a portal under Invincible, sending him to a different world. Debbie watched as her son fell helplessly into it.
"Mark! No!... You're a monster!"
"Huh?! You think you're innocent, Debbie Grayson?! In the half of the universes you've joined your son and husband in their bloody campaign while they kill billions!"
"I don't know what you're talking about, but I didn't raise a murderer!" Debbie glared at Angstrom as Oliver was scared.
"I've been in many universes, but I've never seen this little one. He's quite the curiosity…"
*Tremor*
Angstrom felt the earth shake again and frowned. "Honestly, I didn't want to get involved with an Invincible I couldn't handle… but… how I imagined Walker is capable of taking on that thing."
...
(Near-Earth Space)
"What?" Markus, confused, grabbed his head, still recovering from the previous blow. That defense was terrifying to anyone who knew who had struck him.
Viltrumites increase their power naturally in two ways: one is through their version of senkai, where they recover when near death, and the second is simpler—by age. Viltrumites grow stronger as time passes.
This makes it with each century, a Viltrumite becomes stronger even if he doesn't fight, but it makes Invincible even more incredible. Of course, he got help, but he still managed to fight the strongest of the Viltrumites before the age of thirty. Now, five hundred years later, that brat had become [INVINCIBLE], and his name had become true.
Of course, in his destiny, his path, in his world, Allen Walker was never there...
"Did you feel that?" Allen appeared behind Markus and the first thing he did was mock
"..." Markus recovered and turned to face him. Now he was even more puzzled about the man who had stopped him from destroying Earth, "Are you human?"
Markus had seen the abilities of some humans, like Robot's intelligence, or Eve's power. Even if Amanda were young enough, she'd be an unstoppable monster, and yet no one compared to the one who just struck him.
"Yes, but does it matter…"
Markus, being a man who had lived for so long, didn't act immediately. Instead, he studied Allen for a while, "In my universe, humanity betrayed me first. After my father revealed himself as a Viltrumite and left me half-dead, I was imprisoned by Cecil. They did a lot of experiments to develop weapons to kill Viltrumites… and surprisingly, they survived three Viltrumite invasions… However, I was freed by Conquest, and in a burst of rage I killed 99% of the population, the rest were turned into slaves, I strengthened, and killed Thragg and all his followers… then I sat on the Viltrum throne and began eradicating all civilizations in the universe until only Viltrumites remained as the last race…I returned to Earth after centuries, there were no more humans, but the planet was also dead, so I destroyed the planet."
Allen frowned in disgust. "Hey, kid, what are you trying to do, should I scream for justice and rush at you? Are you trying to provoke me?"
Mark remained silent as he analyzed Allen's words, his expression, and the overall state of his body. After doing so, he closed his eyes for a moment before opening them again.
"I thought you were a hero since you took me out of Earth before fighting... and out of respect for being the first in centuries to land a hit like that, I wanted to reward you."
"That's very kind, your majesty, but screw you, brat. I wouldn't call myself a hero, but I definitely won't let you destroy that world…"
"..."
Markus looked at Earth one more time. "I thought I'd feel nostalgia, anger, or resentment, but after all this time, it just seems like too good a planet for humanity. How about I take it for myself?"
The muscles of the Emperor of the Universe bulged as he woke from his resting state.
Alen tilted his head in disdain. "Same old story, kill me and take it, or die by my hand. That's it, brat."
A resonating impact shook space, and in an instant, Allen's fist was already in Markus's face. A drop of blood came from the Emperor's mouth, but he immediately returned the blow to Allen.
Surprised, Allen grinned before both engaged in a fight that would shake the universe. With constant exchanges of blows, each creates increasingly massive shockwaves in all directions.

(Prehistoric Universe)
Invincible opened his eyes to a world full of vegetation. Let's remember that Angstrom Levy cannot change the coordinates where he creates his portals, so Invincible crossed into the same spot where his house should have been in Universe 1.
Invincible heard noises, and a group of Tyrannosaurus Rexes.
"Is that a sapiens?!"
"Were they not extinct?"
They spoke, and more importantly, they knew it was Mark.
It seems that in this universe, humans went extinct, and it was the dinosaurs who dominated the world. But despite gaining intelligence, they decided to live more naturally, so this world was basically a giant forest and jungle.
"Who cares? I want to try their meat…"
"Wait!"
Invincible flew up, surprising the intelligent dinosaurs.
"He can fly!"
"He must have invisible wings!"
"That's better, more meat to eat!"
Just as the dinosaurs were about to attack, the temperature dropped, and the edge of a metal blade reflected in the dinosaurs' pupils before they were cut down under Invincible's incredulous gaze.
The blue-haired woman floated in the air for a moment before falling.
"You are…"
Esdeath adjusted her military cap and pointed to a door that had appeared not far.
"A message from my master, kid. Finish off Angstrom quickly, or we'll steal your prey…"
"…" Invincible had questions, but his worry for his mother and brother overcame him, and he entered through the door.
...
"Angstrom, stay away from my family!"
"But how—Urgh!!"
Angstrom Levy was struck by Invincible and flew out of the house just in time.
"M-Mark?!" Debbie was in shock just as it seemed like Angstrom was about to kill her. A door appeared out of nowhere, and her son came through it.
Invincible was about to strike Angstrom again, but he opened a portal, and Invincible fell into it.
Angstrom stood up, feeling the pain and tasting his own blood in his mouth. With hate, he shouted to the sky, "WALKER!!!"
His plans were almost ruined by Allen. After all, there was only one person with power similar to his own, and that power could be used so easily.
...
A/N: It was a strange day for Allen. On one side, he helped Invincible, and on the other, he fought to the death with him. 🍷🗿
