Boom—! Boom—! Boom—!
On the screen, a pillar of golden-red light tore through the sky, an eruption of pure destructive energy.
Hades' ship, the Heart of the Demon, was utterly disabled by the strike, half of it reduced to dust. The residual energy surged forward, smashing into a distant mountain with unstoppable force.
With a deafening roar, the mountain's peak was obliterated, stones flying, dust blotting out the sun.
This was—the roar of the Thunderflame Dragon!
Across countless worlds, shockwaves rippled.
Academy City, A Certain Scientific Railgun universe.
"No way…"
Kuroko Shirai stared at the screen, her teleportation calculations utterly thrown off. "Misaka-senpai's Railgun is powerful, but that range, that sheer destruction… it's basically a mobile nuclear weapon!"
"Grr…"
Mikoto Misaka gritted her teeth, clutching her Guta keychain. She wanted to argue, but the truth was in front of her. Reluctantly, she admitted, "I hate to say it, but that move, 'Roar,' in terms of pure destructive power… yeah, it's slightly stronger than my Railgun. Just a little, though!"
Dragon Ball universe, Mount Baozi.
"K…ame…ha…me…"
Goku stood in the clearing, copying Natsu's stance, hands cupped at his mouth as he tried to focus his ki in his throat.
"Ha!"
He expelled a burst of energy.
A soft wind stirred, rustling a few leaves.
"Hmm… not quite." Goku scratched his head with a goofy grin. "Seems harder than I thought to blast ki from your mouth. But that Natsu guy's strong! If I used my hands, I could flatten that mountain too. I'll have to see if I can learn this 'mouth blast' trick someday!"
On a spaceship, Dragon Ball prequel timeline.
"Hmph. Pathetic—power level of five."
Raditz snorted, flicking his tail dismissively. "That kind of attack only works on a low-level planet like Earth. Against me? One finger and they're toast."
Super God Academy universe, Demon One.
"Your Majesty, the analysis is complete."
Demon Atto bowed behind Morgana. "That boy, Natsu, carries a high-tier 'dragon' genetic factor. His last attack reached the peak of a second-generation Super Warrior, even brushing the threshold of a third-generation God."
"Second-gen peak?"
Morgana tapped her black-painted nails on her throne, curiosity flickering in her eyes. "A roar that can level a mountain… that gene engine is interesting. Atto, find the 'Fairy Tail' universe. If we can capture him and turn him into a demon—even a weaker version—it'll be enough to mess with Kesha."
Smoke cleared on the video feed.
Natsu panted hard, his lightning and flames dying down. That last strike had nearly drained him completely.
"D-did we… do it?" Gray held his wound, anxiously watching the ruins.
Reality, however, was crueler than they imagined.
At the center of the rubble, a suffocating black magic rose like a resurrected demon god.
"…To push me this far…"
Hades emerged. Ragged, scorched, and battered, he looked wretched, yet his presence radiated an even deeper, more terrifying power. Slowly, he lifted his hand and removed the eyepatch over his right eye.
No eyeball remained. Just a deep, infernal red, a window into the abyss itself.
Demon's Eye—Open!
Boom!
Purple-black magic erupted, warping the surrounding space. Stones defied gravity, floating.
"Time to show you what the abyss of magic looks like."
Hades formed a hand seal. The crimson demon eye shimmered with otherworldly light.
"Ultimate Magic: Heaven's Executioner, Divine Punishment!"
No dazzling light. No massive explosion.
The rubble, dirt, and debris twisted, merged, and reshaped into grotesque, screaming Earth Demon Blocks.
They surged toward the exhausted Fairy Tail members like a tidal wave.
"Damn it… I can't move…" Natsu collapsed, his body heavy as lead.
A massive Earth Demon Block raised its fist to crush him.
Bang!
At the last second, an ice wall appeared.
"Don't give up, idiot Natsu!" Gray, bloodied and battered, threw himself in front of Natsu.
"We are Fairy Tail!" Erza swung her broken sword, smashing the approaching demon. "As long as we breathe, we never fall!"
Lucy, Wendy, and even the gravely injured Laxus forced themselves to stand, forming a protective line around Natsu.
"Lend your strength to Natsu!" Erza shouted.
"Yeah!"
This scene struck a chord across countless worlds.
One Piece universe.
"Waaah… so touching!"
Luffy sniffled through tears and snot. "That's what friends are! Fight together 'til the end! Come on, Fire Guy! Knock that one-eyed old man away!"
"True courage of the sea!" Usopp yelled, fists trembling but raised.
Bungou Stray Dogs universe.
Orphan Nakajima Atsushi stared at the screen, eyes wide with admiration at comrades refusing to abandon each other even while injured.
"If… I could have friends like that…"
Code Geass universe.
Lelouch's violet eyes flickered with a complicated emotion.
"Bonds, huh? Foolish… but undeniably, they can create miracles."
Back to the video—the final battle.
"Natsu! Go!"
Gray, Erza, Lucy, and Wendy combined their last strength, hurling Natsu like a cannonball toward Hades.
"This is… everyone's belief!"
Natsu roared in midair. Though the Thunderflame Dragon's magic was spent, he burned with his life force and the guild's will. Flames and lightning reignited along his fists.
"Dragon Slayer Secret Art: Crimson Thunderstorm Blade!"
"Foolish!" Hades sneered, commanding the Earth Demon Blocks forward. "What can you do now?"
But Natsu didn't stop.
He smashed through the demons, broke through the dark magic, and charged at Hades.
"I'm not fighting alone!"
"Behind me… is all of Fairy Tail!"
Boom!
With a deafening roar, Natsu's punch, fueled by everyone's faith, slammed into Hades' face.
The screen went white. All viewers instinctively shut their eyes.
When the light faded, Hades' ship was shattered into fragments falling into the sea. Hades himself lay on the ground, the Demon's Eye dim and lifeless.
Victory—Fairy Tail!
Back in the Fairy Tail world.
"We won! We really won!"
The guild erupted in cheers. Natsu stared at the screen, fire puffing from his mouth. "Yes! My future self really is the strongest!"
"Don't get cocky," Erza said with a smile, though her tone was stern. "Future battles will be even tougher. We're far from strong enough. Starting tomorrow, full training for everyone!"
"Yes, ma'am!"
Heart of the Demon universe.
Silence blanketed the ship.
Hades stared at the darkened screen, unmoving. Slowly, he stood, one eye gleaming with malice.
"Is this my future? Defeated by a flock of fledglings?"
"No… seeing the future means fate has already changed. Fairy Tail… I'll have to eliminate you early."
Real world, a small apartment.

Boom!
A surge of electricity coursed through Mason, every cell buzzing. His previously weak body strengthened under the lightning. His mind flooded with new techniques for controlling electricity.
He clenched his fist; sparks danced across his fingertips.
"This… is the feeling of power!"
Mason drew a deep breath, ambition blazing in his eyes. With this power, he finally had the means to survive in a world awakening to spiritual energy.
"But this is just the beginning."
"Since the first video worked so well… might as well strike while the iron's hot."
He opened the newly acquired Multiverse Resource Library, searching for his next video idea.
"Something even bigger than Fairy Tail… more spectacular… more despair-inducing…"
His eyes locked on a name: Uchiha Madara.
The man who stood alone against the entire Ninja Alliance, making even the Five Kage despair.
Especially that move—the Falling Meteor of God's Power.
Mason smirked, fingers flying over the keyboard.
The next video—production started.
