The world of heroes had faced villains, disasters, and wars. But no quirk, no criminal, no All For One compared to what surfaced when the Creepypastas proved to be real. They weren’t quirks. They weren’t mutations. They were nightmares made flesh, legends born from humanity’s darkest fears. Some were once human, twisted beyond recognition. Others had never been human at all. Heroes tried to stop them. Villains tried to use them. Both were erased. By 2014, humans discovered ways to kill a few of them. Hunters boasted of victories, until the death toll of Creepypastas reached 30%. That number was the breaking point. They stopped hiding. They fought back. And when five cities were destroyed in under six minutes, the name everyone feared returned to the surface. SlenderMan. The Tallest. The Faceless. The Endless. He had been most active between 2009 and 2014, then vanished, as if the world’s fear had gone quiet. But now he was back—taller, stronger, impossibly powerful. News helicopters tried to capture him, only for static to corrupt every frame. One helicopter veered too close; it crashed seconds later as SlenderMan stood unmoving on a skyscraper. What the world saw before the static consumed the screen was enough.

Japan tried to fight. Sixty percent of their government collapsed. Eighty percent of their military was annihilated. Even villains were torn apart. On live broadcast, SlenderMan ripped the arm and leg off Japan’s president before the signal cut out. The world froze. The United States, bold enough to send help, lost ten percent of their military in two minutes. Their tanks, soldiers, jets—all erased like dust. They retreated instantly. No one else interfered. The silence was global. And then came the report—SlenderMan was in Musutafu. Half the city already gone. He stood outside U.A., staring at the building without moving, his faceless head tilted slightly. Inside, Class 1-A gathered, trembling. Midoriya’s hands shook as he flipped through his notes. “Th-There’s nothing here… nothing. He’s not a villain, he’s not a quirk… h-he doesn’t even fit into any category—” Bakugo snarled, though sweat dripped down his face. “So what?! He’s just some freak in a suit, right? I’ll blow that bastard apart—”

“No, you won’t!” Iida snapped, his engines sputtering nervously. “Kacchan, if entire armies failed, if cities vanished in minutes, what could we possibly do?” Uraraka hugged her arms tightly. “Half the city’s gone already… h-he’s just standing there, watching us. Why? Why U.A.?” Todoroki’s eyes stayed fixed on the window, his voice low. “Because this is where the next generation of heroes is. He’s not attacking. He’s… waiting.”

Silence fell as the static on the nearby monitors deepened. The screen flickered, showing only the faceless figure outside. SlenderMan did not move. But everyone felt the pressure, the suffocating dread. The weight of something far older, far darker than quirks or heroes. The image dissolved into static, leaving only the sound of the wind outside and the racing hearts of the students. The world was watching. And U.A. was next.
