I. A Fiery Greeting
The abandoned warehouse was the perfect stage for a confrontation, and the League of Villains was quick to act.
Dabi, the man of blue fire, didn't wait for introductions. His Quirk crackled with dangerous intensity, enveloping his hands in flames that burned much hotter than normal fire.
"I don't know where you came from, but if you can make All Might tremble, you're either a threat or an asset," Dabi said, a look of disdain frozen on his face. "But don't take Shigaraki-kun for an idiot."
He unleashed a wave of Blue Cremation Fire toward the group, aiming at Megumin and Kaguya, the most obviously fragile among them.
Goku smiled, raising a hand as if he were a child playing with a garden hose. The Ki in his hand created an invisible force field. The blue fire, which would have instantly charred steel, deflected harmlessly to the sides, surrounding them without ever touching them.
"That's some bright fire! But it doesn't burn much!" Goku said, sounding disappointed.
Dabi's frustration was palpable. "Impossible! My fire melts anything!"
While Dabi dealt with the Ki barrier, Himiko Toga saw her opening. Her Quirk, Transform, was activated by ingesting blood. She lunged at Erza with chilling speed, her knife seeking a superficial cut.
"A cool outfit! But it looks way too clean! I want to see it stained red! I want to be you!" Toga shrieked, her eyes filled with playful mania.
Erza didn't need a second to react. In an ultra-fast Requip, she swapped her Flame Empress Armor for the Heaven's Wheel Armor. She created a rotating field of swords around her body. Toga's knife clashed against the blades, sending sparks flying.
Toga retreated, grinning. "Wow, so fast! You're very sexy!"
"The villains of this world are strangely... immature," Erza muttered, ready for a counterattack.
II. The Psychokinetic Wall and Extraction
As the chaos unfolded, Tatsumaki floated nearby, disinterested. She was tired of the noise and the low power levels.
"Too much commotion. Not even a challenge," she said with a sigh.
With a single thought, she created an impenetrable dome of psychic force around the Dimensional Anchor, the pulsating point of negative energy. Then, she extended that force.
Dabi's Blue Fire, upon touching the dome, curved inward and was compressed. The villain felt a sudden and overwhelming pressure, as if he had jumped into the depths of the ocean. His own flames were used against him, pinning him to the ground with invisible force.
"Damn it! I can't... move!" Dabi grunted, his Quirk completely suppressed by the telekinesis.
Toga, being more agile, tried to flank Erza, but the same invisible gravitational force snatched her up, hoisting her twenty meters into the air and keeping her suspended. Her knife hit the floor with a metallic clink.
The henchmen, who were planning a coordinated attack, were lifted and tossed gently (by Tatsumaki's standards) into a pile of rubble, where they remained trapped.
"See? Silence," Tatsumaki said with a smug smile.
Kaguya took advantage of the quiet to run toward the Dimensional Anchor, which was vibrating in the center of the warehouse.
"The Anchor is saturated with negative energy. It matches the residual Ki. Ready for extraction!" Kaguya said, applying a containment seal over the object.
III. The Arrival of the Symbol of Peace
Just as Kaguya finished securing the Anchor, the roof of the warehouse exploded in a thunderous roar. A gigantic fist of wind burst through, shattering what was left of the structure.
All Might had arrived.
In his muscular form, the Symbol of Peace landed in the middle of the chaos, his eyes searching for the intruders who had caused the destruction at U.A.
He took in the scene: Dabi and Toga immobilized by an invisible force, the henchmen trapped, and a group of strange people surrounding an object radiating Ki.
"I am here! Because the Symbol of Peace must protect this world from unimaginable threats!" All Might shouted, his voice booming. "You are the ones responsible for the U.A. incident! Surrender now!"
Goku turned, his eyes shining with excitement. Finally, someone with energy worth noticing. All Might's Ki was incredibly potent and focused.
"Whoa! Your energy is the biggest in this world! Looks like it's time for a good warm-up!" Goku exclaimed, dropping into a fighting stance.
"Wait, Goku!" Erza shouted. "Our goal is the Anchor. This isn't a fight."
All Might, seeing Goku's stance and sensing the overwhelming difference in Ki, hesitated for a moment. This wasn't a villain. This was a force of nature.
"I have no intention of hurting you, young man. But that... thing you have... is destabilizing my world," All Might said, pointing to the Anchor in Kaguya's hands.
Megumin, who had been watching the conflict develop, pointed her staff at the ground beneath the pile of rubble where the henchmen lay.
"It's time for a smoke screen! A little Explosion for the road! Thanks for the fight, Hero!"
The explosion wasn't apocalyptic, but rather a sharp burst of Mana. A torrent of crimson energy hit the ground, kicking up a thick, hot cloud of dust that filled the warehouse instantly.
"EXPLOSIOOOOON!!!" Megumin screamed before fainting, falling into Erza's arms.
IV. Final Extraction
The smoke created the perfect distraction.
"Now, Goku!" Kaguya ordered, while securing the Dimensional Anchor inside the crystal sphere.
Goku didn't hesitate.
"Goodbye, All Might! You're the strongest! I'd love to fight you again sometime!" Goku shouted, laughing.
He placed two fingers on his forehead. The team vanished from the warehouse just as All Might dispersed the smoke cloud with a gust of wind.
All Might stared at the empty space where the dimensional travelers had stood. The villains remained immobilized and terrified, but the real danger was gone.
"They're gone..." All Might whispered, his hero's facade dropping into an expression of extreme concern. "A threat that even I cannot contain. The world must prepare for interdimensional travel."
End of the Fifteenth Act.
