Fairy Tail: Strongest Creature

Erigor's face twisted with rage. He was the infamous "Death God" Erigor, yet this brat from Fairy Tail dared to ignore him.

*Boom!*

A fierce, violent wind surrounded Erigor as he summoned his magic. He raised his arms, index and middle fingers held together, channeling energy toward his hands.

"Stinking brat! I don't care what kind of monster you are or how tough you think you are. This move will tear you to pieces!"

"Take this!" he yelled. "Evergreen Gale!"

Erigor's fingers formed a cross, releasing a compressed wind blade that slashed toward Su Yan with devastating force.

*Boom! Boom! Boom!*

The blade's path left destruction in its wake, tearing apart everything it touched—even the train tracks.

"Su Yan! Look out!" Lucy shouted, panicked at the sheer power of the attack.

The wind blade struck Su Yan, flinging him back through the air and crashing him into the train.

*Crash!*

The force shredded part of the train upon impact.

"Su Yan!" Lucy screamed, her heart sinking.

Erigor laughed, triumphant. "Hah! Stupid brat! That should teach you! It's a wonder you lasted this long against my magic, but now it's over."

Suddenly, a figure emerged from the debris, standing tall and unharmed.

"What?!"

The Eisenwald members stared in horror.

"He's… alive? And unscathed?!"

"Impossible! That was Mr. Erigor's strongest spell!"

Lucy's eyes widened in disbelief, her voice a whisper. "Su Yan isn't even scratched?"

Erza, watching, nodded thoughtfully. "Su Yan's gotten stronger. It seems he hasn't been slacking at all."

"I wanna go up against him!" Natsu clenched his fists, fired up.

"Happy" grinned. "You'd lose, Natsu."

Su Yan turned to Erigor, a slight smile on his face. "Being alive is such a nuisance sometimes."

"No! I refuse to believe my strongest attack didn't touch you! Who are you?!" Erigor shouted, frustration etched into his face.

Suddenly, Karacka, a member of Eisenwald, pointed at Su Yan, trembling. "I… I know who he is! Long black hair, cyan crest, pitch-black mace… A monster you can't kill no matter what! You're… the 'Undead Demon Emperor'—Su Yan!"

"What?!"

"That's just a legend!"

"How could it be true?"

The Eisenwald members recoiled in terror.

Though Su Yan's name was known in stories, few had ever seen him in person, assuming his legend was just that—a myth.

"Undead Demon Emperor?" Lucy echoed, confused.

"Happy" nodded. "That's Su Yan's nickname."

Over the years, Su Yan had taken on numerous high-stakes missions, often outside the Kingdom of Fiore. His unmatched strength and seeming invulnerability had earned him the title "Undead Demon Emperor" across the land. 

Su Yan rolled his eyes. *Who came up with that stupid name?* It made him sound like a villain in some story—invincible, inhuman, and doomed to be defeated by a hero. 

Erigor's face darkened. He'd heard tales of the "Undead Demon Emperor," the man who had supposedly survived a battle against countless soldiers without a scratch. Yet, he never imagined facing him now.

"Damn it!" Erigor muttered, realizing how close he'd been to achieving his plan.

Su Yan shrugged. "It looks like you're out of moves. Time to end this."

"Brat! Even if you are the 'Undead Demon Emperor,' don't think this is over! I might not be able to kill you, but you can't break through my storm armor!"

In an instant, Su Yan appeared beside Erigor, his mace cloaked in a dark, fierce aura.

"So fast!" Erigor's eyes widened in panic as he barely registered Su Yan's approach.

"Thunderous Strike!"

Su Yan's mace smashed into Erigor's face.

*Bang!*

"Gaaahhhh!" Erigor's scream filled the air as his storm armor shattered instantly. He hurtled backward, slamming through multiple train cars before finally collapsing to the ground, unconscious.

Su Yan scoffed, dusting himself off. "All that talk for nothing."

The remaining Eisenwald members gaped, stunned into silence. Their ultimate weapon, Erigor the "Death God," had been defeated in a single blow. Any thought of resistance vanished.

Dropping to their knees, they raised their hands in surrender. "We give up!"
