Roshi, Bulma, and Krillin arrived on the scene to find only Piccolo there. 

Roshi: Huh? What happened here? 

Piccolo: You're going to need the Dragon Balls. Goku has been killed. 

Bulma: WHAT?! GOKU WOULD NEVER HAVE LOST TO- 

Piccolo: It happened. And- 

He revealed Gohan in his hand. 

Piccolo: I'm going to train Gohan to combat the Saiyans. Two more are coming to earth, and they're even stronger. 

Krillin: WAIT A MINUTE! You're just saying that so you can eat him! 

Piccolo: WHAT?! HOW DARE YOU! I AM NOT SOME SAVAGE!!! 

Roshi: Piccolo, I should warn you, you're about to open a dangerous gate. 

Piccolo: What? Goku's wife? 

Roshi: Never underestimate a mother's love for her family. 

Piccolo: Yeah right. Try to stop me, and I'll kill you. Bye! 

He then takes off. 

Soon...

(Y/N): AGH! 

You landed near a giant building where a bunch of souls were being transported to. 

(Y/N): Well, this is- 

You saw no halo. 

(Y/N): Oh good. 

Team RWBY: We're okay!/That's a relief!/So, where is this? 

???: The Otherworld. 

Kami appeared. 

Ruby: Kami! 

Kami: Just as I predicted. 

(Y/N): Wait, where's Goku? 

Goku: Hey guys, I made it. 

Goku was back in his clothes, though he had a halo on his head this time. 

(Y/N): Damn. Guess we need the Dragon Balls for this then. Look Kami, there's- 

Kami: Yes (Y/N), I'm well aware. And that's why you all need to get stronger. 

Ruby: How? 

Kami: To see the ruler of the Galaxy, King Kai. 

Weiss: There's a ruler of the galaxy? 

Kami: Yes. Come now, let's proceed. 

He lead you all through the station to a big man in a chair. 

King Yemma (The Man who judges where one goes to heaven or hell!) 

King Yemma: Hmm ... let's see here. 

He looked through all of your personal files. 

King Yemma: These 6 here. They have done such meritorious achievements, enough to send them all to heaven, and yet you want them to cross Snake Way and see King Kai? 

(Y/N): But we're not dead yet. 

Kami: Yes, but we can make an exception. 

Goku: Wait, did a guy named Raditz come by here? 

King Yemma: Yes, your brother? I sent him to hell. 

Ruby: Did he pick up a fight? 

King Yemma: Yes, but I easily dealt with him. 

Goku: Wow! Maybe we should train under him! 

Yang: Hell yeah! HEY BIG GUY! CAN WE- 

Kami shut up Yang. 

Kami: Yang, lower your voice. He can hear you. Besides, King Kai is stronger. 

King Yemma: I heard that Kami, it looks like you need more training here. 

Kami: (scared) Uh ... forgive me King Yemma! I didn't think you would hear that. I mean you have such big ears and- 

King Yemma: You were never that funny. But- 

He did all the paperwork quickly. 

King Yemma: Done! Just run done Snake Way and you will get there. By the way, we take no responsibility for what happens there. 

Kami: Best of luck then. 

(Y/N): Hey, tell Mr. Popo to whip Krillin, Yamcha, Tien, and Chiaotzu into shape. 

Ruby: Oh, and Korin and Yajirobe owe us like several Senzu Beans! Years worth! 

Kami: Yes. I understand. I can only hope that Piccolo can raise Goku's son well. 

And so... 

An Oni guided all six of you to Snake Way. 

Oni: My, I still can't believe it. Going up Snake way, are you sure you're all in good health. 

Yang: 100%! Hell, look at Goku! He's perfectly fine! 

Goku: Yeah, being dead isn't rally that big of a deal! 

Ruby: So how is King Kai like? 

Oni: King Kai stands for everyone in the Galaxy! He is our ruler! 

Then a giant snake road appeared. 

Oni: Just follow the road and you'll find King Kai. 

Weiss: How long is it exactly? 

Oni: 1 Million Kilometers. 

Weiss: HOW MUCH?! 

Goku: Uh ... has anyone ran the whole thing? 

Oni: Yes, King Yemma has done it, and in the past 100 million years. 

Yang: Guess we're going to be the next ones! 

Oni: Oh, and if you fall off, you will end up in Hell. 

Goku: Okay, let's fly then gu- 

(Y/N): NO! IDIOT! THAT CAN WASTE OUR ENERGY! 

Goku: AGH! Oh, that's right. I forgot about that. 

Blake: Goku, you forget about a lot of things. 

(Y/N): Well, here we go. 

Yang: Okay, let's see who can get there first! ON YOUR MARKS! GET SET AND- 

Everyone: GO! 

You all proceeded to run down Snake Way. 

Weiss: This better not take us a whole year! 

With Piccolo... 

Piccolo: Hey, wake up! 

Gohan was sleeping. 

Piccolo: WAKE UP! 

He threw him into the water! 

Gohan: AAAAAAAAAAAAAGH! I'M UP! MOM! I'M SORRY I WAS SLEPEING L- HUH?! Wh-Who are you?! Where's my Dad?! DADDY?! DADDY! WHERE ARE YOU?! HELP! HELP M- 

Piccolo: SHUT UP YOU BRAT! OR I'LL SLIT YOUR THROAT! 

Gohan did so. 

Piccolo: Now listen, your father is dead. He gave his life to save you from that kidnapper. 

Gohan: Wh-What? 

Piccolo: Don't worry, he'll be brought back in one year thanks to the Dragon Balls. But that kidnapper has two friends who will come here. And they're even stronger than him. We have to get stronger or earth is doomed. 

Gohan: But I can't fight! 

Piccolo: You have powers that you don't even know yet. And I will train you to bring them out. 

Gohan: How? 

Piccolo: LIKE THIS! DODGE! 

He punched Gohan into a rock! 

Gohan: AAAAAAAAAAAAAGH! 

He ended up destroying the rock! 

Gohan: What the?! Did I do that? 

Piccolo: Yes, your power seems to come in when your emotions are at their peak. And then only for an instant. But I will teach you how to master it. 

Gohan: What do I do? 

Piccolo: I want you to survive on your own for six months. And then I will teach you how to fight. 

Gohan: WHAT?! But I don't want to die of loneliness! 

Piccolo: You won't be alone, there will be blood-thirsty mothers waiting for you. 

Gohan: NO! DON'T GO! 

Piccolo: Listen! The time for childish behavior is not for now. You have to be ready physically and mentally. You are part of the Earth's survival. Goodbye. 

He then leaves. 

Gohan: NO! DON'T GO! I- WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH! 

On Kami's Lookout... 

Popo: Kami, is there something bugging you? 

Kami: I believe Piccolo seems that he is indeed different from before. Ruby might be right about him. But ... we do not have long. 

Popo: You mean that- 

Kami: Yes, I think Piccolo might die to the Saiyans. If he dies, I die, and the Dragon Balls die too. He might know this. 

Popo: So that means that- 

Kami: Yes, the next time they are used, will be their last. 

Back with Gohan... 

Gohan: MR. PICCOLO! HELP ME!!! 

Gohan was running from a dinosaur! 

Soon... 

Gohan was on a cliff. 

Gohan: I'm ... so ... hungry. 

A bunch of apples fell near him. 

Gohan: YES! FOOD! 

He ate them as quicky as Goku and then fell asleep. 

Piccolo: Damn brat. Why? Why did I- It's nothing. He's only just one boy. 

After a while, Gohan saw the moon. 

Gohan: Wow, I never saw it like that before. 

But then- 

Gohan: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH! 

He transformed into a giant ape like Goku! 

Piccolo: WHAT THE HELL?! 

It began to go on a rampage! 

Piccolo: WHAT?! Wait, is this what Raditz said about-

He remembered Raditz mentioning about the Ozaru. 

Piccolo: THE MOON! LIGHT GRENADE!!! 

He destroyed the moon, causing Gohan to turn back to normal. 

Piccolo: To think he could have this because of his blood. It seems that I was right in removing the effects. I hate to think of what could happen if Raditz became like that. Maybe I should remove the tail. 

He then removed Gohan's tail. 

Piccolo: Now then- CLOTHES BEAM! 

He gave Gohan clothes similar to to Goku's but with the symbol of Kami. 

Back at Kame House... 

Yajirobe showed up. 

Yajirobe: There you guys are. Krillin, we got to go. 

Krillin: What? Yajirobe what are you doing here? 

Yajirobe: Well I originally wanted Korin to handle this, but he said, "I'm busy with the Senzu Beans! You do it!" 

Krillin: And you agreed to it? 

Yajirobe: Yeah. Kami is going to train you guys. As for the others, they're training with some guy named King Kai or something. 

Krillin: Right. Well, at least there isn't- 

???: KRILLIN! 

Chichi appeared in a hover car with Ox-King too. 

Ox-King: Uh ... hey there. Long time no see. 

Krillin: Oh hi Chi- 

She grabbed him by the neck! 

Chichi: TALK NOW! WHERE ARE GOKU AND GOHAN?! AND DON'T EVEN THINK YOU CAN BULLSHIT YOUR WAY OUT OF THIS! 

Krillin: Okay, don't freak out. But Goku died and well ... Gohan is being trained by Piccolo. 

Chichi: Huh? 

Chichi fainted. 

Roshi: Did she faint? 

Krillin: Yep. 

Ox-King: Don't worry, she'll get up and probably calm down after a while. That being said, does anyone know how to cook? 

Krillin: (Sigh) I'll handle it. 

Meanwhile ... as six months have passed... 

Gohan: Oh hi Mr. Dinosaur. I'm really sorry about this. 

It goes to attack him, but Gohan jumped to dodge and blasted it. 

Gohan: It sucks, we could have been great friends. 

???: Well done, Gohan. 

Piccolo appeared. 

Gohan: Mr. Piccolo? 

Piccolo: Now our training begins for real!
