Chapter Text
Ever since the alien spaceship appeared in the sky, everything had gone to hell very quickly. Izuku was at UA in class 1-A with his classmates in the middle of hero class when suddenly his Danger Sense started to go haywire. He acted quickly, activating Full Cowl. He left the classroom in the blink of an eye and used Black Whip to reinforce the school's structure, then the world trembled and the school alarms sounded.
UA had barely survived the explosion; thanks to Izuku, the building didn't collapse completely, but many areas were weakened. A hole that opened up allowed Izuku to see the state outside…
Tokyo had been reduced to a pile of rubble, the damage likely extending even further than Izuku could see, and high in the sky, a black machine floated… A sinister-looking spaceship had caused tens of millions of deaths in the blink of an eye, and Izuku knew it; his Danger Sense told him so. All the previous wielders of One For All lay silent before such destruction.
At this moment, the surviving heroes were already in action, although it was unknown if they could do anything against the colossus that loomed menacingly in the sky.
The danger sense blared again, and Izuku promptly moved, dodging a surprise attack from a multi-headed, shape-shifting brown thing flying through the sky. "That thing is fast," he thought. "I must eliminate it," he added. "Protect the ship!" In a rage, Izuku punched the alien, which exploded into pieces… but quickly regenerated, returning to its normal state as if nothing had happened.
"Nice try," he exclaimed. "But I—" In the blink of an eye, Izuku destroyed all the marbles on Melzargard's body, turning the alien into black sludge. The young hero had noticed the marbles during the first regeneration and correctly deduced that this was the source of its regenerative powers.
"Izuku!" Ochako shouted his name as she floated through the same hole he had come from, followed by the rest of her classmates, only to be shocked by the sheer destruction, all worried about their families and friends in the city.
But before he could say anything, his danger sense beeped again; the ship was preparing to fire again, this time directly at the school area. Without thinking twice, he fired at the ship, using 100% of One For All and using Black Whips when dozens of bullets fired at UA. He used Black Whip to grab the bullets and launch them back at the ship from the sky. The ship's hull withstood the barrage of bullets he sent, but it couldn't withstand Izuku's furious attack on the underside of the ship, tearing all the cannons to pieces and leaving the ship defenseless, before infiltrating the ship, in the blink of an eye knocking out all the aliens he encountered and interrogating others.
All of this led up to this moment: the door to Boros's hall was destroyed by a single blow. As Izuku reached the core that held the ship aloft and the room of the one responsible for the attack, all the aliens were knocked out except for Geryuganshoop and Groribas, who were too great a threat for Izuku to knock out.
The leader of the invaders looked at the invader still seated on his throne. His golden armor had a menacing glow due to the purple light emanating from the core. Lord Boros looked at the invader, who, in that costume, had a terrifying aspect. He could sense an immense power hidden within the young hero's body. Meanwhile, Izuku felt the warnings of Danger Sense and the voices of the One For All wielders warning of the danger Boros represented.
‘So this is the best warrior this planet can offer? I can feel immense power coming from him’, Izuku stared at Boros fervently beneath his mask. "You... are responsible?"
The alien rose from his throne, ignoring Izuku's question, while grinning dangerously with his shark-like teeth, “Wonderful… Before we fight, let's introduce ourselves… I lead the Dark Matter Thieves group, I am the ruler of the universe, my name is Boros.” Izuku bit his lip, anger seething beneath his skin, but he decided to play along and try to get more information, “I am… Deku.”
“Deku…” The alien spoke Izuku's hero name as if savoring it, “Why did you attack us… Why attack Earth? Are you some kind of… space pirates? You are the ruler of the universe? Is that true?” The little information Izuku had obtained, along with the somewhat disjointed answers from his subordinates, was beginning to paint a horrifying picture.
“Why did I attack Earth?” The smile faded slightly as the alien began to descend the throne steps toward Izuku, “There’s a prophecy… I was a traveler, exploring the universe and devastating everything, but I was too strong. Eventually, I realized there was no one who could face me. I ended up feeling the torment of utter and overwhelming boredom. Then one day, a great seer told me that on a distant planet, a being would be my equal, someone who could receive my passion for battle… That was almost twenty years ago. Do you have any idea how far I traveled to be here? My men thought the prophecy was a lie, a fairy tale created to distract me, but now I’m sure it’s true. Let’s give my existence some impetus! That’s why I AM HERE!”.
