"HAAAAAAAAAAAA!!!"
Upon touching their fingers, Goku and Vegeta both disappeared into a golden glowing light, a massive wave of power erupting from it.
"?!!!" went Kid Buu, shocked, as even he was pushed back by it.
When the light cleared, neither Goku nor Vegeta stood there. Instead there was a single man, clad in an orange and black vest with white pants. He had long spiky golden hair down his back like Super Saiyan 3 Goku and a gold with a white-tinged aura like Arcane Super Saiyan 2 Vegeta. There was also bolts of white electricity zapping all over his aura. The man had the combined facial features of Goku and Vegeta.
"So it comes down to this," said the man, his voice that of Goku and Vegeta's in sync. "I hold the power of both Goku and Vegeta! I am Gogeta!"
"Grrr…" growled Kid Buu, furious at the man's lack of fear.
"You show no fear not of arrogance, but of ignorance! There has been no one capable of challenging you until now!" shouted Gogeta, before he vanished.
Kid Buu looked around, trying to find his new opponent when suddenly he was sent upward, his face malformed by a monstrous uppercut. Kid Buu squashed his face back in, before Gogeta appeared behind him and planted his elbow into his back.
"GUAHHHHHHH!!!" screamed Kid Buu, purple blood and vomit coming out of his mouth, but Gogeta was not finished. He grabbed Kid Buu by the arms and planted his feet against the monster's back. Like he was pulling fresh molding clay apart, Gogeta easily tore off Kid Buu's arms while sending him through several piles of debris.
Kid Buu immediately flew upward out of the rubble and spawned two new arms, which he used to beat his chest with.
"This is your end, Buu! Accept it!" shouted Gogeta, before taking off to continue beating the crap out of Kid Buu.
Now, he was being beaten and covered in his own purple blood.
Kid Buu growled angrily at Gogeta.
"I told you…you can't defeat me. Even with the short amount of time I have left in this form, its more than enough to destroy you," said Gogeta.
"RARRRRRRRRRRRRRRRRR!!!" roared Kid Buu, finally having enough, as he released pink steam of great anger from his pores. He flew upward, high into the sky. Kid Buu raised a hand above his head and began charging pink energy into it.

"NO! Not that technique!!!" screamed the Supreme Kai, as he watched the fight in the crystal ball.
"Are you telling me that technique is worst than it looks?" asked the Elder Kai, looking up from the crystal ball.
"That technique is what Majin Buu would use to destroy a planet!!!" shouted the Supreme Kai, not wanting another planet to suffer from Buu's nihilism.
*************************************************************************
"Like a spoiled child, you decide to destroy everything just because you're not winning anymore," said Gogeta, unnerved as he watched a giant ball of pink energy form above Kid Buu's head.
"RARRRRRRRRRRRRRRRRRR!!!" roared Kid Buu, thinking not even Gogeta could survive having the planet destroyed. Unlike himself, Gogeta couldn't regenerate himself.
"Very well…I'll end this right now!!!" shouted Gogeta, before he put his hands in front of him. He held them vertically apart and parallel, as he gathered energy between them. "ARCANE BIG BANG KAMEHAMEHA!!!"
From his hands, Gogeta fired a blue with white-tinged energy beam, similar to the Kamehameha, but far much stronger. It was surrounded in the same white lightning that had been zapping all around Gogeta.
The beam met with Kid Buu's planet-destroying energy ball, not just overpowering it, but tearing through it completely. With nothing in its way, it continued right towards Kid Buu.
"GRAHHHHHHHHH!!!" screamed Kid Buu, realizing something as the beam approached him. For the first time in his life, he actually felt fear. Nothing had been powerful enough to threaten his life… challenging Gogeta was a mistake he would never get to make again.
With one final scream, Kid Buu was enveloped by Gogeta's energy beam, it vaporizing every molecule of his body. When the light from the energy cleared, nothing was left of Kid Buu. The miniature terror of the galaxy that ended so many worlds and civilizations had finally been destroyed once and for all... or so they thought.
