"Phew! I'm alive!" Gohan chuckled, whipping a whole lot of sweat off his forehead. Things looked dicey there for a minute with Boo's mouth blast on one end and the blob from the other. With those odds, he did the only thing making any sense, put up a barrier and hoped he'd get out of it well enough to keep on fighting.
It worked, he'd be dead otherwise but just from looking around, something weird happened. "Where am I? Hello? Can anyone hear me?"
His voice echoed through, wherever he was. It looked like the inside of a cave, a very dark purple cave with unnatural looking bulges on the ceiling and floor with sticking looking,... veins connecting them both. Dropping his barrier, Gohan gently knelt on the floor, placing his hand to the surface.
"T-This is... alive?!" He realized, feeling something close to a blood flow running underneath. "C-Could it be...?!"
Focusing on his other senses, Gohan closed his eyes and tried to confirm his suspicions but it wasn't easy. Whatever was happening inside this place was interfering with his ability to feel ki. Even breathing was difficult, the air, the atmosphere of there, it all felt wrong. In spite of this, with more effort than he'd usually need, Gohan felt what he needed.
"I-I'm inside Boo..." He whispered, feeling a fresh bit of sweat break out. "B-But how...?!"
He scratched his head, rewinding back to when Boo's attacks finally got to him. "I didn't feel getting hit by the blast... Could he have dropped it in time to let that goo eat me?!"
Before he could wonder more, the inside of Boo started getting hot, really, really hot and he could more easily feel a build up of ki... somewhere outside he guessed.
"C'mon brats!" Majin Boo's shout reverberated from inside him so loud Gohan had to cover his ears. "Fuse and fight me or I'll blow everything up! You got five seconds!"
"Oh no! He's gonna blow up the Earth!" Powering up, Gohan was about to blow a hole through Boo when more shaking suddenly made him lose his balance.
"You're gonna pay for that!" He heard Goten and Trunks both shout from the outside. Was that the fusion of theirs everyone was talking about? Truten or something? "The unstoppable Gotenks will smash you like nobody else!"
When Boo shook this time, it got followed up by the whole of his inside suddenly shrinking down, squashing Gohan then growing back to normal before he suddenly jerked forward, making Gohan smash face first into him.
"Aw, gross,..." He hovered out of the wall, not trusting himself to stay on balance any other way. Loud pounding noises echoed through the inside, probably Boo and Gotenks trading attacks with each other. From what his dad said, Gotenks was pretty strong, maybe good enough to win on his own, but if that were true, he'd have already done it,...
"Boo's regeneration must've given him trouble as it did me, I wish we could get rid of it somehow,..." Suddenly, Gohan remembered something he hadn't thought about in a very long time: Cell. Specifically, something Cell said about his own regeneration all those years ago.
"I-I think I got it! Dad! Dad can you see or hear me?!" He shouted, hoping they could somehow give him an answer but nothing came. It probably wasn't surprising, considering where he was. "Look! Cell had a core in his head that let him keep regenerating! What if Majin Boo has something like that too! From inside, I could find and destroy it so we could finally beat him!"
No answer, deflating some of his enthusiasm. Sighing, Gohan looked back up to the ceiling, speaking more softly. "I don't know if you got any of that, but I'm hoping you have! So please tell Gotenks not to go overboard, not while I'm still stuck in here, okay?"
Instead of getting the answer he wanted, something big and strong drove into Boo right where he was, smashing Gohan's entire body and sending him flying into the opposite wall. "Ugh,..." He spat out some blood. "I better find that core fast,... I don't know what'll happen to me if Gotenks tries vaporizing Boo,..."
"Gohan! Gohan! GOHAN!" Goku shouted, shaking the crystal ball with Old Kaiohin complaining and beating on his chest about it. His son couldn't hear him as he got himself out of the wall Gotenks punched him into and started flying up. "Can you hear meOOOWW!"
Old Kaioshin kneed him in the crotch, making him drop the crystal ball. "He obviously can't hear you, idiot! So stop taking your frustrations out on my stuff!"
"Oof,... sorry,.." He whined out, kneeling to make the pain down there stop. "But his idea's good! Quick! Get me over t'Kaio's! He'll let me talk to Gotenks!"
"Fear not, with my Kai Kai ability we shall get there in due haste-" A loud ringing noise close by cut Kibito off, it sounded sort of like a phone but it was coming from the crystal ball.
"What could Enma want at a time like this, I wonder?" Old Kaioshin waved his hands at it and sure enough, Kind Enma was on the other end.
"Finally! It's been eons since anyone's used this number!" Enma shouted, looking pretty nervous. "What'd you do, lose it?!"
"Nice to see you too Enma," Old Kaioshin with a mean look. "Now, what do you want? We've got a crisis to solve!"
"That crisis is precisely what I'm calling about in the first place! I saw Gohan get swallowed whole and that idiot Gotenks failed already, so I've got a backup plan right here!"
"What could he mean?" Kaioshin asked. The crystal ball showing Enma also gave them a good look at his office where several ogres and a regular soul were standing around. Enma shuffled through his big book where everyone's record was kept and with a mean look at the soul close by, thumped on a page with a big seal saying "Approved!"
A second later, the soul changed from a little poofy yellow ball into someone Goku didn't expect to see again.
"You kept im?! King Enma, yer a genius!"
"Die! Die! Die! Die! Die! Die! Die!" Gotenks shouted at Boo, tossing out dozens of ki blasts with every arm thrust. After punches didn't work out he decided to blow him away. But Boo kept changing his body to dodge him, like making his arms, legs and even whole body super thin and wiggly. It didn't stop him from sticking his tongue out or from trying to flip Gotenks off with those weird mitten hands.
"Nya nya!" He wiggled his whole body up and down, looking like a freaky, chubby snake hovering in the air. "Can't hit me, can ya runt?!"
"Oh yeah?!" Smacking his arms together, a whole lot of Gotenks' energy blast stopped flying forwards and instead for each other, and a whole lot of them had Majin Boo right in the middle of where they'd meet up. Boo's stupid mouth bit his own stupid tongue when he freaked out and noticed a whole lot of pain coming right for him.
But it didn't work, in no time flat, his body curled up into a ball then flew directly down fast enough to dodge all the blasts. It rolled down there for a second then ricocheted off the floor and flew right towards Gotenks.
"Oh crap!" He blasted away from it but Boo's arms shot up and grabbed the ends of his long Super Saiyan 3 hair, making the fused boy scream something fierce in pain when it got pulled, hard. "Ooooowwwww! Lemme go you pink bastard!"
"Have it your way!" Boo spun his mostly ball-shaped body in-place, making him and the spinning Gotenks look like a big wheel going around in the sky real fast. Then it stopped dead with Gotenks being smashed right down into the ground, denting it for miles away from the impact crater.
"Ugh, I think I'm gonna puke," Gotenks said, holding his belly to fight back the bad feeling he was getting from it. It didn't get better when Boo suddenly smashed down from up top, pinning him down with his butt and feet. He gave Gotenks a mean grin while his arms were turning into something looking like jackhammers.
"Now I'm gonna smash you, you littleAAAAAGGGGGHHHHHHH!" Gotenks couldn't hold it back anymore, being spun around then smashed hard in the belly made a whole lot of puke practically jump out of his mouth and right into Boo's mid-gloat.
"AAAAAGGHHHHH!" Boo screamed on, getting off of Gotenks and trying to gargle out the vomit stuck in his throat. "KILGHHJYUOO!"
"I almost feel bad for im," Gotenks said, slowly getting back up on wobbly feet. "But now I got a chance!"
Wiping some of the last puke away from his mouth, the fused boy grinned then powered himself back up, first creating a pair of ki balls in each hand before smashing them together and moving both arms over to his head. This was his chance! To finish off Majin Boo for good and avenge everyone he'd killed!
"Say hello t'my little-"
DON'T DO IT! A loud cut into Gotenks' mind, making him feel like he got a slap to the face from one of his moms. Gotenks! Don't fire on Boo! Gohan's in there!
"What... Is th-that... Goku, I mean dad?!" He wondered, letting his guard drop while Boo kept on choking.
Yeah! It's me! I'm callin' from the afterlife! Listen t'me! Gohan got eaten up by Boo but he's alive inside o'there!
"A-Are you serious?! S-So I just almost killed..." Before he could finish, a recovered Majin Boo smacked Gotenks across the face into a nearby canyon.
"Gonna make you hurt a lot for that!" Blowing lots of smoke out of his face holes, Boo shouted and kept his promise by firing off dozens of ki blasts into the canyon. Pretty soon, the whole thing was going up in a big mess of pink explosions and smoke with Gotenks a yellow blip flying away from it.
"B-But how am I supposed to fight this guy then?! If I go on the offense I'll probably hurt Gohan but if I run away he'll do some weird crap with his body to attack me next! I'd have to keep im still for a long time!"
Are you of all people complaining about finding an unorthodox method of winning?
Gotenks felt the mom slap feeling again. "M-Mister V-Vegeta... I mean, dad?!"
Hmph, who else? Now pick your mouth off the floor and get to work, the fate of the Earth rests on what you do next!
"Yeah, no pressure! I just gotta make this pink freak stay still without fighting him or letting him beat me up!"
Aw c'mon! You guys've been pullin' out crazy tricks to win all the time!
For once, I agree with Kakarot. You've created ghosts, ascended to heights neither of us ever thought possible, but your wild imagination has run dry now?!
I wouldn't have left things up t'you guys if I didn't think you couldn't pull it off!
Precisely, now go! Go and win like I know you can!
"Enough running brat!" Boo stopped firing and super speeded his way over to Gotenks, kicking him in the face towards a stone wall. While he was pinned there, he felt tears in the corner of his eyes, but not because he was getting sappy, Gotenks didn't get sappy. It was from his aching nose, for sure.
"Alright, dads! I'll make you both proud! Just watch! Hhhyyyyaaaaaa!" Blowing the wall away Gotenks crossed his arms and tapped his left foot while Boo rushed towards him. When he got really close, he took a big breath then shouted: "TTTTIIIIMMMEEEEE OOOOOUTTTT!"
The shout was so strong, Boo's face flew back at the sides, he had to shake it like a horse for it to get back to normal. "What's the big idea, runt?! Why time out?!"
"We're not gettin' anywhere like this man."
"Huh?!" Boo tilted his head to the side. "What'd you mean?"
"Look, I say I'm the strongest, and you say you're the strongest but we're goin' about it all wrong man, strengths about well, strength, right?" He flexed his muscles with Boo giving him an approving nod. "So, why don't we stop all this laser firing, flying, ghost bombs, stretchy crap and do it leak REAL men, huh?"
"Hrm..." Boo rubbed his chin, looking kinda,... thoughtful if you could call it that. "What do I win when I win?"
"You get to kill me and be the strongest in the universe, but if I win when I win, you go bye-bye instead, so, you interested?"
"Hhhhrrrrmmmm... Okay, what do you wanna do?"
Gotenks grinned. "We're gonna need some help first!"
"So Gohan lives..." Piccolo breathed a sigh of relief, allowing himself a small smile. Goku and Vegeta, who'd been teleported from various spots in the afterlife were brought over to Kaio, first contacting Gotenks and now him. "Thank you for telling me."
Save your thanks for later, focus on helping Gotenks with whatever he needs.
Yea, Majin Boo an' him are doing something weird.
Goku wasn't wrong, Piccolo could sense a lull in the battle, for some reason, the two of them were just... standing around from what he could tell, but doing what? He could not say. His smile vanished when he felt the two of them flying,... together,... towards him. "What is he doing?"
... I dunno, he said it was a surprise...
"Terrific," Piccolo ground out, bracing himself against a blast of wind when the two of them landed mere feet away from him.
"Yo! Piccolo!" Gotenks rushed over to him. "You can make stuff, right?"
"I can use magic materialization, yes... why?"
"Sweet! So!" The fused boy slapped his hands together. "We're gonna need a couple of REALLY strong chairs and an even stronger table."
"Chairs? A Table?!" Piccolo repeated, blinking all the while. "What the devil for?!"
"How else are we gonna have our arm-wrestling contest?"
"... WWHHHAATTTT?!"
Kudos to my editor Kagari for ironing out the grammar & spelling kinks.
