Dragon Ball Super - The Shadow Dragon Saga
Alone in the ruins of West City stood two figures.
One was a bruised and beaten man standing in an orange gi lit with an unearthly blue, sparking flame.
The other was a large humanoid creature with white armor with blue "flesh" in the gaps. What stood out most was seven small orange spheres embedded in its chest.
"So, Goku. Have you decided to give up? I've been fully restored to full power and added the full strength of my fellow Dragons to my own, yet you are still weakened from all of the fighting. I'm nearly 10 times stronger than you are now! You can't defeat me!" boomed a demonic voice from the strange armored monster.
"You wanna bet, Omega? KAIO... KEN!" shouted Goku, as he added red to the outside of his flaming blue aura.
"The Kaioken? I didn't think that an amplifier like that would work while using something like Super Saiyan. But it seems you can control it. Though, the strain of using this blue Super Saiyan form and the stress of using your Kaioken on a power so large must be killing you. Not to mention your Super Saiyan power is already volatile compared your normal power," boomed the "Dragon's" voice.
"Heh. You may have learned about me before Buu, but none of you Dragons learned anything from after I fought Buu. 'Super Saiyan Blue' is calm and perfect to control, maybe even more so than my normal ki. As such, I can still go higher. Kaiooooo Ken... TIMES TEN!" roared the blue saiyan, his red outer aura rapidly expanding.
"Wait, times wha-" the monster began, before fist slammed into his face. Had he not been busy trying to process the fact that his opponent had just multiplied his immense strength by ten, dodging would have been easy from this distance. However, it was stupifying to hear that Goku had just brought himself up to the level of Omega.
"So," said the Dragon, "you can make yourself as strong as ten Goku's. That might have been better to use at the start though. Even though you may have the strength of a god, you're already weak. This will be the end of you! And then, I will ravage the universe! I WILL CONQUER ALL! I was not the "alpha" but I shall be the universe's "omega"! I AM OMEGA SHENRON, AND I WILL DESTROY YOU!" roared the Dragon.
Several days earlier...
"Man, the Twin Universe Tournament was great! Only two of the Universe 6 fighters could make us use our god ki, but it was still fun testing out our regular strength, right Vegeta?" asked Goku, too cheerfully for Vegeta's liking.
His 'friend' responded, "Maybe for you, Kakarot. You had to challenge yourself to beat Botamo, got to fully test your regular strength against Frost, and fought Hit all-out. All I did to Frost was punch him- not even full force- using my regular Super Saiyan strength, without god ki even. Then, that Metal Man, Magetta or whatever, makes me have to actually start using God Ki-and actually is putting up a damn good fight- and he decides to turn the arena into an oven. I could barely breathe. And after that, Hit took me down in under a minute!"
"Well, you could've taken your time with Frost. You didn't have to knockout Frost in one punch, and I thought you wanted to be challenged Vegeta? So what was the problem with the Magetta fight?"
"Shut the HFIL up Kakarot!" retorted the widow peaked Saiyan. To this day, the Z-Warriors will jokingly say "HFIL" to mock Yemma for his short stint of renaming Hell to 'HFIL'. The ridicule of the dead was enough, but the ridicule of the living was just salt in the wound.
"Jeez Vegeta, you're always so angry. We ended up winning the Super Dragon Balls in the end. Hmm... Dragon Balls... Oh, hey! I should probably revive King Kai
In Other World, on a small planet between Heaven and Hell...
"Took you long enough," grumbled a round blue figure, as he moved his antennae to search his the Earth. "Anyways... Maybe I was wrong. Whatever I sensed shortly before Goku and his friends left for the tournament was moving really fast towards. Something that fast should be too strong to simply hide from my view, especially when I'm only searching one planet. I must have just imagined it," King Kai concluded. He could search for it when he got resurrected. In the meanwhile, he began to wonder why he was talking out loud.
Back on Earth, in West City...
"Hey Bulma. When the Dragon Ball scattered after Beerus told him to scram, did they ever turn to stone? He didn't really grant a wish, he just tried and failed to find the last Super Dragon Ball," asked the Turtle Hermit's apprentice.
"Huh? No, I don't think they turned to stone. What do want the Dragon Balls for?" responded a blue haired woman in a lab coat.
"I just thought about the tournment and remembered we were competing for Dragon Balls. Then I remembered I hadn't revived King Kai yet, so I figured I should probably do that right now. He's probably pretty mad at me by now," Goku said with his trademark grin.
Now, it was time for our 'hero' too set out to gather the Dragon Balls to revive Kaio-sama, or he and his friends called him, King Kai. An epic quest to restore to life a god he had wrongfully pulled into his mess. His first time gathering the Dragon Balls, it had taken him from his home on Mount Paozu to the home of the Ox-King, to the island home of the legendary Turtle Hermit, to the castle of 'Emperor' Pilaf.
This time, he did it in 20 minutes. (He got hungry after he collected the first two.)
