He stood on the other end of the field, staring down his opponent intensely. A chilling breeze swept across the land and the intensity was growing, stretching past the point of no return. The battle was looming and there was no walking away until one was victorious, until one was defeated, and Waluigi was more than ready.

And so was Shaggy. It had been a long time coming and this was it, it was time for the showdown of the century, and SMG4 had his camera out.

"We got an exciting match today!" An announcer declared, it was Axol the manga artist, "And for our two combatants, we have the wah-master, WALUIGI, and facing him from the other side, we have SHAGGY!"

Waluigi clenched his fists and his eyes glowed with power, Shaggy stared at the wah-man with a smirk.

"Waluigi time!" Waluigi sneered.

"Like, I'm gonna walk all over your face." Shaggy remarked threateningly.

It had started months after the Waluigi Apocalypse had come to an end, when Waluigi had been texted about Ultra Instinct Shaggy and when someone had taunted him, saying that he had competition. Undoubtedly, they were talking about Waluigi's super form he took whenever he felt neglect. And then, it had intensified after the Battle of Anime Island, when Shaggy memes came up again.

Now, after enough back and forth online, after so much mockery and parody, the two super-powered beings were about to throw down in the most intense and perhaps exciting battle in YouTube history. And the whole world was watching.

"LET'S GET READY TO RUMBLLLLLLLLLLLLLLLLLLLLLLLEEEEEEE!" Axol howled.

Waluigi roared and levitated into the air, taking his shirtless and muscular deity mode. His staff appeared in his hand and his eyes gleamed as bright as a blue sun. A gold aura surrounded Shaggy as his Ultra Instinct became fully instinctive, the mystery-solving sleuth-turned half-deity levitated and faced down the Wah man.

From afar, Princess Peach stood by her castle with an anime doll in her hand, watching nervously.

"Oooh, I hope my castle doesn't get destroyed again this time." She whimpered.

Waluigi and Shaggy's stares became more fierce. And then, it was show-time. The wah-man made his first move. He shot towards Ultra-Instinct Shaggy with a raised fist, soaring at high-speed, and then, he threw his cuff only for Shaggy to teleport out of the way and reappear behind him.

The Wah-man turned and thrust out his staff, trying to immobilize Shaggy, but the Ultra-Instinct fighter blocked Waluigi's move and the staff flashed intensely and glowed bright red. Waluigi gripped it hard, not feeling any pain. Ultra-Instinct Shaggy threw a punch, which Waluigi blocked with his hands, then he threw a punch and struck Shaggy hard across the jaw.

Shaggy flew backwards, spinning in the air, then he propped himself straight again and streaked towards Waluigi like lightning. He grabbed him, then he soared high towards the sky and took his opponent with him.

"UNBELIEVABLE!" Axol exclaimed, "The fight's just starting and Shaggy managed to gain a foothold after being knocked out by Waluigi! Let's see how they do from here!"

"What else have you got?" Ultra-Instinct Shaggy taunted Waluigi.

"I haven't even gone all-out yet..." Waluigi replied with a smirk.

He head-butted Shaggy and kicked him, knocking the Ultra-Instinct fighter off him. Waluigi clenched his fists harder, arched his shoulders, and, with a loud "wah", he went all-out with his powers as a surge of energy exploded forth and a stronger aura of power surrounded WaluRambo-Waluigi. His fists crackled with blue energy and his eyes glowed with immense power...

Waluigi focused on Shaggy and launched himself towards him, flying at breakneck speed, closing the gap between the two combatants. He tackled Ultra-Instinct Shaggy hard, grabbed his arms and head-butted him again.

And then, the super-powered Wah man punched the Ultra-Instinct power fighter in the face and spun around, lifted his leg, and performed a roundhouse kick.

The lanky anti-Luigi kicked Ultra-Instinct Shaggy so hard, it sent him hurtling across the sky. Ultra-Instinct Shaggy managed to regain his senses and strength, then, he flew towards Waluigi and flipped the bird.

"Like, f*** you, Waluigi!" He taunted, "Nobody wants you in Smash!"

"WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHH!"

That was a big error. Waluigi's rage boiled to the surface, fueling his strength, and the sky darkened. Shaggy came closer and the wah-man pointed a finger at the super sleuth, a bolt of energy shot forth from his body and struck Shaggy hard. The super-powered Ultra-Instinct fighter spun in a daze, taken off guard by Waluigi's attack.

Waluigi went all out, he flew towards Shaggy, punched him in the face, maneuvered around him, and then struck him in the back. He spun around like a ballerina and kicked his opponent across the back of the head, then he grabbed his arms and spun Shaggy around like Mario would with Bowser.

"SO-A LONG, EH, SHAGGY!"

He threw Shaggy with all the fiber and strength in his body, throwing him higher into the sky. Waluigi watched him fly, then he relaxed his arms, put his legs together, concentrated his powers, and activated Waluigi Launcher mode. A purple aura encircled him and Waluigi streaked high into the sky, racing towards Shaggy with outstretched hands.

Fueled by every single ounce of power that he had, the wah-man rocketed across the blue yonder, streaking through the clouds, and grabbed Shaggy just as they ascended higher and the star-filled vastness of space surrounded them.

Waluigi flipped him over his head, released his grip, then he flipped himself around and brought down his leg upon Ultra-Instinct Shaggy in a hard kicking motion.

WHAM! Shaggy yelled as he fell towards the Earth, Waluigi initiated Waluigi Launcher mode again and streaked down towards his falling foe. He rammed into Shaggy, head-butting him in the torso, and gripped both of his sides. Adrenaline rushed through him and his foe too, he felt the rush of wind as Waluigi streaked back down to Earth with his foe slightly incapacitated.

"This is quite the reentry, folks!" Axol announced, "Waluigi and Shaggy are coming in like a meteor, but it's not looking so good for our green shirt-wearing food-loving ultra-instinct sleuth as Smash's not-so lanky assist fighter has the upper hand over him!"

'Man.' SMG4 thought, 'The views will be through the roof.'

Ultra-Instinct Shaggy looked up at WaluRambo Waluigi, glaring at him with a half-smirk and a half-scowl. Waluigi picked up speed, the ground was getting closer and closer, and a huge surge of Wah power was coursing all around and through the wah-man's being...

KA-BOOM! They hit the earth, causing an explosion of dirt, as a mushroom went flying. The dust cleared and Shaggy lay in a crater with Waluigi atop him, laughing with glee.

"You really had a chance?!" Waluigi taunted, "THINK, SHAGGY, THINK!"

Shaggy glared up at the wah-man and, just then, a blast of golden energy erupted into the air and Waluigi went flying as Shaggy rose from the crater, surrounded by an even brighter aura of deity power. Super Ultra-Instinct Shaggy chuckled, lagging a finger at the wah-man as he hit the ground.

"Oh, I have a chance alright." Shaggy quipped, "And you didn't!"

"YOUR POWER IS NO MATCH FOR THE POWER OF WALUIGI!" Waluigi yelled, he levitated back into the air and prepared for one last throw-down with his foe.

Shaggy streaked towards him and then teleported away, reappearing behind Waluigi in a second. He kicked him in the back of the head, warped around the purple evil Luigi, and punched him in the nose. Shaggy twirled and rapid punched the wah man, throwing an endless barrage of fists and pummeling Waluigi into oblivion.

Waluigi grunted and tried to block the strikes, but the being he was facing had become more powerful than him. Ultra-Instinct Shaggy went nuts, launching anime-style strikes, and letting Waluigi have it. Punch after punch, he overpowered the wah-man, then he punched him into the air.

Ultra-Instinct overcame rage and neglect. He rocketed towards Waluigi, pulled up beside him, and kicked him in the side. Shaggy teleported in front of the wild wah man and punched him in the face, then he launched a roundhouse kick and sent him crashing into the earth. Waluigi landed on his face and rolled over on his back, feeling dazed from Shaggy's attacks.

And then, he looked up, watching with wide eyes as Ultra Instinct Shaggy dove in for one final blow.

KA-WHAM!

"Knock out!" Axol cried, "It's all over for Waluigi! Looks like Ultra Instinct Shaggy has once again proven to be superior to all who dare to go up against him and underestimate his power. What an exciting battle of epic proportions. Waluigi may have been strong, but Ultra Instinct Shaggy proved himself to be a far more powerful foe than he ever expected!"

"Waaahhh..." Waluigi groaned as he lay in the crater in a daze. His powers diminished and he returned to his normal state, staring weakly up at his victorious opponent as Ultra Instinct Shaggy smirked.

SMG4 approached with the rolling camera still in hand and Ultra Instinct Shaggy, looking at the meme man and staring into the camera. And then, Shaggy took flight, flying off into the sky as he basked in the glorious hour of victory while Waluigi lay still, half-dazed from his defeat, as he slipped into a state of unconsciousness...

The End
