Chapter 1: Buu Enters the Time Chamber! Gohan Frees a Kai!?
"Alright, this way to fight the strong guy," Piccolo motioned to the new and improved Majin Buu after he had just so calmly wiped out humanity.
Buu smirked, "You bring Buu to strong guy. Buu beat strong guy."
"Yeah… Yeah just come this way." Piccolo replied as he began slowly walking. 'I need to take the long way around to the Time Chamber, I must give Goten and Trunks as much time as possible without pissing off Buu. I only hope that Goten and Trunks are taking their training seriously. If they've proven anything about Gotenks so far it's that Gotenks is incredibly cocky. I only hope they are able to take this seriously… Goku, how could you leave us with them?' Piccolo worried to himself as he began to take Buu the long way around. Every second he can stall Buu, the boys get 6 minutes more of training in the chamber. 6 minutes that could be the determining factor in the fight for it all.
Meanwhile at the Land of the Kais, Gohan was about to pull out the Z sword. Supreme Kai and Kibito watch, the latter a little skeptical. "You can't honestly think this Earthling will be able to pull out the Z Sword, do you?" Kibito questioned.
"Quiet Kibito," Supreme Kai hushed, "Gohan, please, show Kibito what I'm talking about."
"Uhhh, I'll sure try Supreme Kai." Gohan answered timidly. He grasped the sword in the stone and began yanking furiously. It would not budge though, not even a little.
"Ha! See I told you, he's a weakling!" Kibito laughed, thinking he had been legitimized.
"Shut it Kibito," Supreme Kai snapped before quickly regaining his cool. "Gohan, go Super Saiyan."
"Super Saiyan? Oh right, duh." Gohan laughed as he went full gold and instantly pulled the sword out of the stone like it was butter.
"What! How? How can a mere human be this strong?" Kibito blubbered, shocked at what he was witnessing.
"Well actually Kibito I'm a Saiy-" Gohan was cut off as the sword began to glow and promptly burst into a brilliant light.
The trio stepped back in awe as the sword turned into a man! As the light faded they saw it was an old man to boot, whose attire and skin color was that of Supreme Kai!
"Who are you?" Supreme Kai asked, dumbfounded at this wrinkly Kai-like being.
"A mortal freed me? How did a mortal free me? How come one of the Kai's didn't do it?" The old man barked at Supreme Kai.
"Who are you!?" Supreme Kai reiterated.
"Me? I'm your ancestor you idiot. Call me Elder Kai. I've been locked in that damned sword for many millennia, waiting for a warrior who could release me from my prison." Elder Kai turned to Gohan. "Man you are strong! Hey do you wanna replace this disgrace here as Supreme Kai? I can make that happen you know." He winked.
"What!?" Supreme Kai and Kibito both stuttered.
"Uh, no thanks. To be honest, I'm a little disappointed Mr. Elder Kai. I was hoping I was going to be able to use that Z Sword to defeat Majin Buu." Gohan sighed.
"Ah yes, I know your plight my boy. Well, don't panic! I can train you and make you a lot stronger!" Elder Kai chuckled.
"Really! That's great!" Gohan burst out, thrilled that there was still hope.
"Wait, back up a moment!" Supreme Kai interjected. "Why were you trapped in the Z Sword Esteemed Ancestor?"
"Esteemed Ancestor? What am I, a god!?" Elder Kai cackled.
"Uhhh… Yeah." Supreme Kai replied, looking shocked and slightly annoyed at the presence of this new kai.
"I didn't ask you to be a smart ass fact checker East Supreme Kai!" Elder Kai seethed. "Why is it than in all the years since your fellow Kais have passed, you haven't raised and trained more Kais to help you!?"
"Uhhh…" Supreme Kai was at a loss for words.
"I'll tell ya why, you like being the only Supreme Kai!" Elder Kai stuck his finger in Supreme Kai's face.
"Elder Kai please! I hate what happened to my fellow Supreme Kais, to insinuate I enjoy them dead is…"
"I can read your mind you dolt, I'm a far more trained Kai then you could ever hope to be." Elder Kai cut in, disgusted. "How could you let this all spiral as much as it has, you damn fool!"
"...You're right Ancestor… I have failed time and time again. I am not worthy of continuing as Supreme Kai." Supreme Kai fell to his knees, shocking Gohan and Kibito.
"Don't start feeling sorry for yourself now, it's too late for capitulation, we need you to help considering Majin Buu is on the brink of Universal obliteration." Elder Kai lamented.
"I see, thank you for giving me a second chance Esteeme-"
"You can thank me by shutting the hell up." Elder Kai ordered.
"...Yes sir." Supreme Kai conceded.
"And since you asked, I was sealed in the Z Sword a long time ago by Beerus the Destroyer, a nasty bastard that one. He could probably deal with Buu himself, but last I checked he's right in the middle of a 50 year nap, and if anyone dared to wake him up to get him to deal with Buu… Well he might destroy the Universe before Buu purely out of anger." Elder Kai chortled.
"Mr. Elder Kai sir, what were you saying about training?" Gohan asked, trying to get back on topic.
"Oh yeah, I can make you super strong, a lot more than Buu. But it'll take a good four years to get the job done." Elder Kai explained.
"What!?" Gohan, Supreme Kai, and Kibito all fell backwards in shock.
"Esteemed Ancestor, Gohan doesn't have that much time. Majin Buu may destroy the Universe at any moment now!" Supreme Kai exclaimed.
"You moron, you don't think I know that?" Elder Kai barked at Supreme Kai. "We'll use one of the Extra Dimensional Rifts."
"The what?" Gohan asked.
"Oh of course! How could I be so stupid?" Supreme Kai said as he caught on.
"You asking?" Elder Kai trilled. "Because I think I can give you a few good reasons."
"I'm sorry, but what are Extra Dimensional Rifts?" Gohan persisted.
"Extra Dimensional Rifts are other Dimensions in which time moves differently than the time of the normal Universe." Elder Kai explained.
"Oh! I knew that. I've been in one. On Earth we called it the Hyperbolic Time Chamber, and one year in it would only be a day of Earth time." Gohan said excitedly.
"Ah yes, that is but one of many Extra Dimensional Rifts. The one we will use will allow us 4 years of training time in but one day of Earth time. Which means that after one day you will have gotten the powers you need." Elder Kai continued.
"Really? And you think these new powers could stop a monster as strong as Majin Buu?" Kibito asked.
"Of course. I know Majin Buu's power, and I have no doubts that once this boy here unlocks his potential, he will make easy work of the Pink Devil." Elder Kai concluded.
"How do you know Majin Buu's power if you have been locked i-" Supreme Kai started, before being cut off.
"What did I say about shutting the hell up?"
"... Sorry." Supreme Kai replied, hanging his head in shame.
"Alrighty, that's more like it, you ready son?" Elder Kai asked, turning to Gohan.
"Great! Let's go Mr. Elder Kai! Time isn't on our side right now." Gohan urged as he jumped up and down in angst.
"Alright fine, let's go." Elder Kai began. He then immediately let out a very high pitched powerful tone. After a few seconds a tear out of what seemed to be nothingness began to form right in front of them.
"Wow, you can do that?" Gohan marveled, thinking of all the times in his life where this could have been useful.
"No time for laughing, let's go in now!" Elder Kai croaked as he shoved Gohan in. "As for you two, if we do not get back out in time have Goku and Vegeta fuse. That should buy us enough time." Elder Kai finished as he entered the rift with Gohan.
"Wait!" Kibito started as the rift disappeared. "How does he know about Goku and Vegeta? What could he see while stuck in the sword?"
"Honestly Kibito," Supreme Kai sighed. "He may have seen everything."
As Kibito and Supreme Kai contemplate this mysterious new Kai, Piccolo exhausted every long route he could take, and was now in front of the chamber door.
"Alright, the strong guy is in there." Piccolo told the anxious Buu, praying the boys got enough time.
"About time." Buu grumbled.
"So… You… Wanna warm up out here first?" Piccolo improvised, hoping to milk every second he could.
"No I do not wanna warm up. Buu is very very warm!" Buu boomed.
"Oh of course… What about a quick nap though, I mean we did walk quite a ways, aren't you tired?"
"Move! Buu fight strong guy now! Buu has no time for weak guy's boring words." Buu huffed as he pushed Piccolo out of the way and entered into the Hyperbolic Time Chamber.
Buu rushed inside to see the empty void of the chamber. 20 yards out he saw two small boys, both with a stern expression on their face.
"This is the strong guy? Grrrrrr!" Buu spun to Piccolo, fuming out of his holes.
"Wait for it." Trunks started.
"Because Gotenks." Goten continued.
"Is coming for you!" They both proclaimed in unison.
"Is that so?" Buu turned back to the boys, slightly intrigued.
"That's so... Fu-sion-ha!" The boys chanted methodically as they morphed into the lone warrior; Gotenks.
