Majin Buu began to shout, his vice reverberating throughout the planet.
His opponent, the so-called 'Super Vegito', had driven him to this. The Saiyan had no one to blame but themselves. So now he would destroy everything!
The vibrations he unleashed with his voice mingled with his inner ki energy, casting malevolent bolts of lightning all around. Where the bolts struck emerald ripples materialized, schisms upon the skin of this dimension itself.
His opponent, in their cockiness, resisted of course. They might've had double the brains of one Saiyan, but they were still remarkably stupid. As if he could not still shield himself. As if he couldn't augment his protective barrier with more energy even as he continued to rip apart the dimensional fabric. As if this Super Saiyan fusion could ever break through by merely increasing their own pow-
POW!
A white gloved fist socked Buu hard in the jaw, delivering a fierce uppercut. The pain was not what silenced him though. It was the sheer, mind blowing disbelief that this could be happening!
He fell back, arcing down, and fell into the sea itself, his most recent failed attempt to dominate the battle replaying in his mind as if in slow motion.
This wasn't how it should be! He shouldn't be losing, let alone this badly! He was Majin Buu, the feared demon scourge of the universe itself! More than that, now he was SUPER Buu! He had the mind of a Namekian tactician. The creativity of two imaginative children. And the power of a human-Saiyan hybrid with all his potential unlocked. Plus his own magic, regenerative abilities and immense might.
He was chaos personified! He was death itself! So why was he being humiliated by this two-in-one monkey!
He hit the water at last. And as he did so, he noticed that it was oddly green… and glowing…
Buu, shivered as a cold wind blew across his soaking body, made worse by the gathering velocity of his fall.
But wait… that didn't make sense...
He was wet because he had just hit the water; so how was he in the open air again?
His confusion overtook the shock and humiliation of the Saiyan's blow, fostering a desire to find his bearings. His mind now clearer, he lazily exerted a little ki to slow his descent until he'd come to a complete stop mid-air. Another wave of confusion hit him, though he didn't think it was due to being upside down. His body remaining rigid, he rotated himself 180 degrees, flipping the city below him the right way up.
Where had that come from?
He and the fused Saiyan had been fighting over the sea and in a wasteland of sorts. How did he wind up in a city? And such a pristine one at that. Hadn't he already assaulted all the cities on Earth? There should be some sign of damage somewhere.
He narrowed his eyes, and reached out with his ki infused senses, trying to detect the Saiyan. However, he found no trace of him. He widened his search to the whole Solar System, then the entire galaxy and finally beyond even that. Nothing.
What was going on!?
Buu hated to admit it, but the Saiyan had been winning. Why would he suppress his power, let alone flee their fight? From his four new 'acquisitions' he knew how battle-hungry the pure blood Saiyans were, and if they were now combined together there was no way they'd pass on the opportunity to fight. Especially not someone as powerful as himself!
So where were they!?
On impulse, because he could think of nothing else to do, he tried scanning for other fighters. Even before he'd absorbed anyone, back when his ki sensing abilities were new to him, he had been able to detect other fighters far beyond the Earth's galaxy. That was, after all, how he had known Gohan was on his way when he'd fought the child Gotenks.
His eyes snapped open. Those other fighters… they were gone too!
But there was no way that so many people could suppress their power all at once across the whole universe itself. He replayed his last moments with Vegito, searching his memories for clues. He'd been ripping apart the dimensional fabric when the Saiyan had tried punching through his barrier. He'd reinforced the barrier, then the Saiyan had increased their own power and broken through. He'd fallen, crashed into the water, and then-
Another memory hit him, this one from earlier on. He had been in that strange white room, fighting Gotenks. Wracking Piccolo's mind he learned the room had been in another dimension, one where time flowed more slowly. Piccolo had trapped them all there but Buu had escaped by using the power of his voice to punch a hole in the dimensional fabric. That was where he'd gotten the idea to try that with Vegito.
His eyes snapped open.
Back when he'd decided to rip apart the dimension he'd been tearing open portals everywhere. Could… Could one of them have been… under the water...?
That had to be it!
He couldn't sense anyone else because they were back in his home dimension and he was… somewhere that had no strong fighters…
His body slumped and without really meaning to he lowered himself to the ground, landing in a park of some kind. As if to accentuate his situation, the place seemed to be totally deserted, the street lamps casting long shadows across the grassy grounds. The shadows shifted slightly and, dimly, he realized some people were approaching from behind him.
"Please forgive Usagi's lateness."
"Oh, that's alright Mamoru. After so many years we're both used to it."
"That's right, according to my notes Usagi holds Juban Middle School's record for tardiness!"
Buu gritted his teeth and began to growl, the banality of their conversion irritating him.
"Umino, bringing a notebook along on a double date isn't very romantic."
"Oh, sorry Naru! I promise I'll tear it up as soon as I get home. I promise you'll never see it ever again!"
The ear-grating tone of this boy's voice finally broke him.
Though not as powerful as the one that had opened the portals, Buu let forth a mighty roar of frustration all the same.
Despite his own volume, he distinctly heard a high pitched scream from behind him. Whirling around he spotted the annoying speakers. A girl with short, wavy auburn hair done up with a light green bow. A boy with scruffy brown hair and stupid glasses with a swirley patten. Vaguely he wondered where the third person had gone but he didn't care right now. Right now he was angry, annoyed, and… hungry...
He pointed the antenna at the back of his head tentacle at the couple and fired a beam of pink light at them.
They were so horrified they didn't move. The boy screamed . The girl though, to his mild surprise, didn't.
"Why does this stuff always happen to me!" She yelled.
A moment later two chocolate parfaits, complete with glass holders and a spoon, stood on the ground where once the teenagers had been.
A blue-green tongue licked Buu's lips as he snaked his elastic-like arm across the park grounds. Before he'd reached the spoon though, a mild pain shot across the back of his palm, giving him pause. Seeing the thin scratch on the back of his hand he looked around and soon spotted a red rose embedded into the concrete.
"Chocolate parfaits are a wonderful dessert that brings joy to children and romance to young lovers. To defile them as you have is something I will not forgive."
Buu blinked, then, his expression stoney and unchanged, he turned his neck 180 degrees around. He found the pompous speaker was a masked man in a tuxedo and cape perched atop one of the street lamps. Whilst his head remained stationary, the rest of his body twisted backwards in line with it, the movement making the stranger jerk ever so slightly.
"And just who are you?" He asked deadpan.
The caped stranger leapt to the ground.
"I am Tuxedo Mask."
Buu narrowed his eyes. "Are you a fighter?"
"I am a warrior of justice if that's what you mean?"
"And how do you stack up against every other man in this universe?"
Buu could tell that, behind the mask, the stranger was taken aback by the question. "I can't speak for the universe, but, for what it's worth, I think I might be the most powerful man in this solar system."
Buu groaned and lazily fired off a ki blast.
The stranger dodged, his leap thrown off course by the sheer force of the explosion. Whilst attempting to right himself, he hurled a barrage of roses at Buu, their sharp stems penetrating his chest. Buu blinked and gazed down at the roses. Was this guy serious? He gave the merest of shrugs and the roses popped out, pathetically flopping to the ground.
The stranger gritted his teeth and took out a cane, brandishing it as if ready to duel him. Buu raised an eyebrow and, in a flash, was mere inches away from the stranger. He snatched the cane up and channelled a minute amount of ki through it, disintegrating it to dust. The stranger gasped before Buu flicked his chest. The masked man was sent flying across the park ground, colliding into a tree and finally crumpling like a rag doll, his stupid top hat having rolled out of sight.
Buu stalked up to him, a thoroughly unsatisfied expression upon his face.
"If you are the best your solar system has to offer, then I am going to have to pace myself killing everyone here."
The stranger mumbled something Buu couldn't hear.
"What was that?" He said, bending down and turning his ear towards his victim.
"I'm not the best this solar system has to offer."
Buu raised another eyebrow.
"You don't stand a chance against the Earth's true champion. The most powerful being in the whole Universe." He locked eyes with Buu, shooting daggers at him. "You don't stand a chance against… Sailor Moon…"
Buu's face remained bored and unconvinced as he aimed his antenna over his shoulder and, with another flash of pink light, turned the stranger into a tuxedo-clad chocolate treat.
"Mamo-chan!"
"Huh?" He mumbled, peering over his shoulder.
Another girl, this one with blonde pigtails topped with two buns was staring aghast at him.
The sight of her hair buns made Buu's mouth water. Maybe he ought to turn her into a mochi-bun?
"Usagi, I saw the whole thing before you got here! That monster turned Naru and Umino into parfaits too! Watch out for that antenna of his!"
Buu narrowed his eyes at the talking black cat behind the girl. She looked a little different from the animal people he remembered killing back home, but he supposed some things were constant in every dimension.
"Moon Cosmic Power, Make-Up!"
Turning his attention back to the girl he just managed to spot her grasp the red heart brooch on her chest before her body was consumed by glittering light.
A split second later, the girl stood before him again, but in different clothes. Buu shook his head. He had the strangest feeling that, had he not witnessed the girl change before his eyes, he might not have recognized her.
"How dare you hurt Mamo-chan and my friends! I am the pretty soldier of Love and Justice, Sailor Moon! In the name of the Moon I will punish you!"
Buu said nothing. He simply stared at the girl who had struck a pose, pointing at him with her arms crossed. Then he blinked. Blinked again. Finally, his bottom lip began to tremble and then…
"AHAHAHAHAHAHAHA!"
Buu doubled over, falling to his knees and slamming his fist on the ground, his body shaking with uncontrollable laughter.
"SERIOUSLY!?" He bellowed, through deep inhales of breath. "YOU'RE Sailor Moon!? HAHAHAHAHAHA!"
Sailor Moon pouted and balled her hands up into tiny fists by her side. "Hey! What's so funny!?"
"What's so funny!?" Buu tried catching his breath as he arose to his feet. "That guy over there said you were the most powerful person in the whole Universe. But you're...you're…." He snorted and cracked up again. "You're just a little schoolgirl! AHAHAHAHAAHAHA!"
Amidst his own laughter he heard the black cat address his 'mighty opponent'.
"Sailor Moon quick, while he's distracted!"
"Right!"
Wiping tears from his eyes, Buu spotted the blonde 'soldier' brandishing a pink rod topped with a red heart and tiny gold crown. At the sight of it Buu snorted, his body beginning to shake with repressed laughter.
"Moon Spiral Heart Attack!"
The skinny blonde girl began spinning around, performing a series of ridiculous movements that made the fusion dance look dignified.
Buu had gone positively blue trying to control himself throughout the display but his resolve finally broke and he began to bray like a donkey.
As the girl moved, the cutesy rod began emitting trails of pink glitter as she twirled it in her hand.
"AHAHAHAHAHA! STOP! STOP! IT'S JUST TOO MUCH HAHAHAHAHAHA "
Finally Sailor Moon came to a stop on her knees, holding the 'weapon' above herself, a spiral of pink hearts flying out from its tip.
"AHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA- Wait, what's thaAAAAAAUGHHHHHH!"
Every atom of Buu's being flared with pain as his body collided through the giant pink heart-shaped wall. He couldn't help but scream in anguish, but he found he was also powerless to prevent something else exiting his mouth.
"LOVELY!"
He felt his very being come undone as he vanished up in smoke.
What felt like a lifetime later, the vapour remains of his body coalesced back together, regenerating him as always. However, never before had he reformed in such a state of distress. His body was cold with sweat and he bent over, gasping for breath in a cruel parody of his earlier bout of laughter. His vision blurry, he tried firing off a ki blast in the general direction of Sailor Moon, but found he was far too drained for such a feat.
"Luna the Spiral Heart Moon Rod didn't work!"
Even gripped in pain as he was, Sailor Moon's words infuriated him. He was Majin Buu. How could he be hurt so badly by something with such a stupid name!
"Transform again Sailor Moon!"
As soon as his vision cleared up, that little girl was in for a world of pain!
"Okay!"
First he was going to use his head tentacle to choke her half to death!
"Crisis Make-Up!"
Then he was going to take that stupid cutsey excuse for a weapon of hers and...
"Rainbow Moon Heartache!"
...snap it in two and stick both halves-
Blurred as his vision was, he couldn't help but spot a rainbow of colour pass across him. If not for that he wouldn't have spotted the second heart wall looming towards him.
He let out a strangled gurgle from the back of his throat and, at the very last second, fired off a pink beam from his antenna. At such a close range he could hardly miss. The heart wall would become a miniscule marshmallow, and once he gobbled it up, Sailor Moon would-
WHAM!
"LOVE-LOVELY!" Buu involuntarily screamed as his atoms burst apart again.
This time, it took far longer for his form to corporealize. Even when it had, it took even more time for his senses to reassert themselves. Once they had, he discovered that he had been laying on the ground, curled up in a foetal position and was emitting a tiny, high pitched, moan from the back of his throat. The mere idea of moving seemed utterly ridiculous to him at this moment.
"Luna, he fired something before my attack hit!"
"Yes, but his magic was far too weak to work against yours. And since he's so badly hurt, I think we can safely say he's a mid-tier enemy."
Despite positively living inside the pain coursing through his body, Buu felt the faintest twinge of indignation.
"How do you mean, 'mid-tier'?"
The word was nothing short of salt in Buu's already considerable mental wounds, especially when spoken by the girl.
"Well, your standard attacks usually defeat Daimons and Youma easily enough. But more powerful enemies, like Rubeus or Eudial, can counter your techniques. Since this monster survived those attacks, but is obviously injured, his power level must be somewhere in between."
Buu's moan was supplanted by a low growl.
"No doubt though, he's chock full of evil, negative magic though. It's little wonder you and your Silver Crystal are so effective against him. Still, he's hardly on the level of Queen Metalia, let alone any of the stronger enemies you've fought."
Buu's healing factor kicked in again, this time repairing the damage from his teeth being ground together.
"Perhaps try using your ultimate form?"
"Alright, it's worth a shot."
At this, and with a titanic effort, Buu began to unfurl from his foetal position and roll onto his hands and knees. He kept his head bowed though, his body still in pain. He only looked up when a bright silver light illuminated the entire park.
When the light dimmed his jaw dropped. This schoolgirl's ultimate form was… another change of clothes…
Specifically a flowing white dress that looked even less combat efficient than the miniskirt and bow she'd had earlier. Were this ten minutes ago he might've laughed, now he just felt incredulous and further humiliated. The sensation was accentuated when, in place of a weapon, she seemed to hold up a glittering crystal flower.
As the crystal's light fell upon him he felt… strange. It was as if he was in pain but at peace at the same time. His memories of a thousand burning worlds and screaming victims became blurry, and difficult to remember. In contrast, other memories suddenly became far sharper. Memories of playing with a scruffy puppy and a funny man with a thick black afro and moustache.
"NO! I WILL NOT LET YOU DO THIS TO MEEEEEEEE!"
In desperation and uncertainty, Buu did the first thing that popped into his mind. Gathering up all the strength he had left he screamed as loud as he possibly could!
"What's he doing Luna!"
"I… I think he's using his voice to rip apart the dimensional fabric!"
Though he couldn't see it happening, he could sense the walls of reality beginning to bend and, ever so slightly, break.
"Usagi quick!"
Buu imagined he could hear a soft 'crack' as the first tear in space and time began to emerge. Were he not concentrating on his task, he might've smiled in delight at his wicked work.
"The Silver Crystal! It's the only way!"
That stupid girl! She thought her shiny trinket could undo the damage he was inflicting upon the universe itself!
"You're going right back to wherever you came from, jerk!"
It was over! All over! Everything would be utterly and completely dest-
More silver light. Less shouting.
Buu didn't feel as he had before when exposed to the light. Rather, now he felt like all his vast power had been somehow… turned off…
And he also felt a kind of 'tug', pulling him away from the park and towards one of the tears he'd created in the sky. Only, the emerald green light that should have been there was now a gentle silvery pink. Suddenly weightless he floated up towards the portal, as if carried by a pacifying invisible hand. From his new bird's eye vantage point he witnessed the silver light from Sailor Moon's crystal bathe the park grounds and sew up the portals he'd cracked open. Then the piece of chocolate by the tree transformed back into the masked stranger. The parfaits did much the same, the pair of teenagers reappearing, though they lay unconscious.
His incredulousness at the sight swiftly faded as he sensed something from the portal. Something powerful and hauntingly familiar.
The Saiyan. The silver pink portal was taking him home. There was no doubt at all, he could even detect the faintest trace of sea water. He was being placed back exactly where he'd been before.
He considered what to do. Ironically, the gentle journey into the sky had given him time to regather his strength. He could certainly break free of whatever was pulling him towards the portal...
… Then again…
He went limp, lazily letting the magic pull him through the portal. A moment later he was submerged in sea water, the sensation almost washing away his humiliation.
He decided that he would forget his little adventure and never try messing with reality ever again. After all, didn't they say that there's no place like home? Even if home included a very frustrating Saiyan?
Loathe as he was to admit it, Buu had learned his lesson. Better to fight this blonde Super Saiyan than that blonde Sailor Soldier.
A/N: As a huge fan of DBZ and Sailor Moon I inevitably compare the two franchises a lot. To me, by accident or design, they have a lot of connections that serve to make them a kind of ying-yang to one another, at least for the 90s generation of anime and Toonami kids like myself.
Anyway, it is no secret DBZ fans like to debate 'who'd beat who' and I'm not alone in asking that in relation to DBZ characters vs Sailor Moon characters (there is even a Youtube video pitting Beerus against Galaxia). I was doing this one day at work when it occurred to me that the only DBZ character Usagi would be essentially guaranteed to defeat would ironically be the single most powerful villain from the original manga, Majin Buu. This is due to her Silver Crystal being super effective against demonic entities like Metalia, Death Phantom, etc.
The idea of Sailor Moon, with her style of attacks utterly wrecking a character recognized as being unimaginably powerful, was endlessly funny to me so I had to write it.
