Edit: This started out as a piece made for the ruination, but I couldn't put Nunu through that .___.)
So I changed it to Super buu instead.
I may have overshot the story xp


In an alternate DBZ timeline, where Goku wasn't allowed to come back to life to fight buu, Picollo took it upon himself to be a GOD once more, gather the dragonballs and make 3 wise wishes to stop Buu that would save the earth, and potentially the universe.

1. The first was a sense of self awareness that restricted his impulsive desire for destruction.
2. The second was for him to be removed from the planet with no way to find it.
3. And the third was that he would be (by himself or someone else) removed from the universe before he could destroy it.

Goku was displeased that he or Gohan couldn't fight buu, and Vegeta was dead now, but at least the 7th Universe was safe.
Everything went as planned and the earth was save... accept for one thing. It was only THIS earth in universe 7. Not the earth he'd be sent to, and he would surely find one.

With Super Buu's increased self awareness, he decided that the DBZ universe was just too easy to destroy. He never particularly cared about being destruction incarnate, but now he was bored of it, like everything else he had done. So instead of searching for Ki and going to those places, he roared with all his might, tearing the surrounding parts of the universe into thousands of rifts.
He planned to open them in order to go to other universes. He didn't care which. He was invincible. He just jumped into the largest with the greatest amount of energy.
He soon arrived in a cold region on the other side called the Freljord (league of legends/ Runterra verse). The cold didn't bother him. The boredom was what drove him insane. He was just about to destroy the planet when he sensed an intense, endless darkness within it. It was the void, and its countless watchers inside.

The majin smiled. He had finally found something as terrifying as he was; a worthy opponent. Sense he had opened up several rifts by merely yelling, he managed to unseal the void just by opening a portal to runeterra, and decided to go into the opening hole situated on a glacier nearby. He jumped through it cheering with glee at another chance of fun, before starting and ENDING what was one of the craziest, most savage, ruthless fights and beatdowns to ever take place in runeterra.

Khazix was curb stomped into oblivion, Kaisa was sent flying halfway across the void, the baron nashor became an overgrown piece of beef jerky to the jungry majin, Velkoz was punched in the eye until all he could see was stars, and the watchers could do nothing but... watch in fear, as every part of their domain was devastated by buu. They feared for their own lifes for the first time, even without physical bodies.
Normal creatures couldn't enter the void without possibly being torn apart by the very portal they enter, but to buu, it was nothing.

The entire void was reduced to rubble in just a few minutes... and buu was once again disappointed.

EVERYWHERE he went, no one could challenge him. It made him want to take a thousand year nap at this rate. That is until a large bug jumped out of the smoking mist and landed in front of him. It was the Rift Herald; a giant, legendary beetle that could destroy almost any structure in one attack.
Normally Super Buu would be interested, but now he knew all too well how it would go. The thing would die, and he'd be board again.
Though it did seem unfazed by the fact that he just destroyed its home.
Super Buu let out an energy blast and began whirling it around the bugs head, meaning to make it dizzy and impale it once it fell.
However, the Herald didn't take the bait.

Instead, it started dancing to the light. It was enthralled by the spell. That's when super buu remembered that he had MAGIC! There were all sorts of things he could do! They were all boring, but less so than pointless destruction at the moment. The more he thought about it, the more he realized how one-dimensional he was. It invoked a dissatisfaction in him that he hadn't felt before.
Thanks to Picollo's wish, he was finally aware of himself, and he wanted more than destruction. He wanted control.

If nothing could entertain him for long, he'd MAKE it; take it over with part of his body for his own use. Though it was a simple thought, it caught fire, and the Majin decided to try it on the herald as it danced with his energy. In one swing of his extended arm, he enveloped the herald and brought it to the ground in a pulsating mass of pink goo, before taking over its body and making it stand up. A new, pink tail that acted like an antennae allowed Buu to control it remotely, though it was on the heralds' butt of all places instead of the head.
Though indifferent, a smile spread across his face as he flicked his wrist, making the herald power up and charge into a large pile of rubble with his Ki. In an instant, the pile exploded by the force of impact, and buu once again felt happiness. He now had a slave that liked destruction as much as he did.

Together with the herald, he moved back through the closing portal from the void and into the Freljord, seeking to find another beast to make fight his new slave.
He couldn't sense Magic as easily as ki, but he did sense a special kind of magic nearby.
He gleefully ordered thee herald to go find the source and bring it to him!

The herald, not able to resist, flew at supersonic speeds toward the source, which was willump and the jewel he had been gaurding for centuries.
Nunu was busy helping a nearby village with chores while Willump was eating krugs a few miles away. The two were actually spending some time away from each other for themselves, since they were so different. Even best friends need some time apart. He was just about to finish the last one when the herald shot down and tackled him, sending a shockwave of snowdust across the field of snow. Willump was a tough Yeti, possibly the last yeti, and fought back; biting and clawing at the now super-powered herald. Since the frejlord was covered in sheets of fresh snow, the impact only did damage on it. The rest was absorbed. Willump however, rolled underneath it as it continued to charge him. Not used to its new power, it tumbled several meters away, scraping up snow as its head slid across the ground.

Willump was too shaken up to notice a pink slime spreading around him and yanking him into the air. He let out a confused growl as he was held upside down mid air, and lifted up to Super Buu's level. The latter of whom was sitting with his legs crossed and head tilted, curious as to what he just caught. He had never seen a creature like it... which only made him want to enslave it more.
Willump threw a flurry of magic snowballs at him, more than upset that he was ambushed by an alien AND the rift herald. The powdery snow poofed into smoke as it hit the majin, provoking him to stretch out a hand and blast the Yeti. However, his attack was stopped by Willumps' magic, freezing him in place. Both buu, and Willump fell to the ground as he lost control. Though super Buu could use magic, he didn't fully understand it.

Willump's fall was broken by the ever engulfing slime around his body as he hit the ground. What started out as a puddle around him had rapidly expanded into a large blob trying to eat him... All he could do was use his ice magic to slow it down. It couldn't be frozen!
The sound of large footsteps reached him as the Majin Herald walked up to, and stood over him. He looked it in the eye as it watched him, and for the first time noticed that it was different. It was pink, covered in the very same slime trying to cover him... and even though its body looked fine, he felt that it was trying to break out.

"You're... good..." A raspy voice echoed from super buu, who was casually walking out of the small crater he made on impact.
"But I'm... Better" He said ominously, in a demonic tone as he extended a hand toward the yeti. The slime immediately answered his command and engulfed the Yeti. In seconds, he too was covered in slime and at Buu's mercy... or so the Majin thought. He smirked at first, but then realized something was wrong. He didn't feel like he was controlling the Yeti.
The slime rolled itself off of Willump as it was countered by the powerful magic gem Willump had; the last of the Yeti magic, preserved over centuries. Though super buu was ominously more powerful, his magic couldn't overcome the magic Willump had flowing through his veins! He couldn't understand!
"What... this?" He yelled angrily, encountering something he couldn't control. Willump growled and wiggled, trying to spit up the slime that had poured into his mouth.
He caught sight of the majin again, and tried to wrestle his way out.
Buu merely reached his hand out again, and made his slime cover Willump again. This time, he started dribbling it and bouncing it, as though it were mouthwash across the field before bringing it back to him. Again, His slime couldn't take him over!

Buu was beginning to get envious of this weak Yeti, who somehow had greater magic than he, the destroyer of GALAXIES! He WANTED IT!
"Your mine! OBEY!" he yelled out before lifting and bring down his hand. The slime obediently lifted itself above Willumps disgruntled body, before shooting into his mouth! If he couldn't control him from outside, he'd do it from within! The Yeti glurked and swallowed the forceful mass into him as it coated and filled every inch of his belly, and even some of his intestine!
"NO ONEBUT BUU SHOULD HAVE ULTIMATE MAGIC! GIMME!" Buu yelled as he once again covered Willump. This time, he used his head tentacle to shoot magic onto willump, super charging it. His magic now overpowered Willumps', but only partially. The slime separated again, revealing a thick, pink tail on the yeti, which resembled Buu's head tentacle. "YES, GIVE ME YOUR MAGIC!" Buu yelled as he was about to start reverse transmitting and absorbing Willump's magic through the tail.

Willump however did something he rarely ever did before buu could absorb anything, and shot a freezing true-ice bean from all 6 of his horns. Buu was too close to escape as he was covered in unmeltable ice. For a few moments, everything stopped... everything seemed to be over, until the slime jumped back to action and engulfed his horns. Willump roared as his mana was sucked up through his horns and into the slime.

Though True ice is unmeltable, it isn't UNBREAKABLE. Super Buu violently thrashed until the ice was gone, before roaring at Willump.
He was furious at how he had been outsmarted not once, but twice. However, he was learning! He now realized that no magic can work without mana to empower it! Willump slouched in the slime as it absorbed his mana, rather than it attempting to overpower such magic directly.
"This time you won't outsmart me! NO ONE OUTSMARTS BUU!" He yelled as he began absorbing the mana from his slime, leaving Willump with none. Even going so far as to declaw the Yeti magically, to reduce his ability to run away!

Willump sank into the hypnotic slime as the new tail took control of his body. Crudely, and forcibly, Buu had now filled every inch of him with slime that he couldn't just cast out! The mass swelling and bulging in his deep belly between his leg.
Buu calmed down as his prey finally stopped resisting. Even though his body was still rejecting his slime, Buu was fine with that. He considered it a fitting humiliation that he was outsmarted. Then he got another idea.

"You, monster, will make Buu magic!" he yelled as Willump was finally engulfed for good; his new tail pulsing and channeling buu's ki into him in order to produce magic in his body for his new master. The power causing such a surplus as to make his groin bulge as the slime forms vines to absorb the excess through his body. "And you, bug! You will do Buu's laundry!" He yelled at the obedient herald before they all flew off.

Thus began the tale of Buu, Lord of the Freljord
