(I should point out that in this story Goku was never changed into a kid and there is no SSJ4, actually I've eradicated GT because I just didn't like it really…)
Gohan and Goku stood facing each other in the Son Goku house. Gohan had his arm stretched out and in his palm, the shiny blue stone wobbled.
"I was training with Pan and we found it!"
cough
Gohan looks around but Goku simply walks to the window, opens it and looks down.
"Hey Pan!" he said cheerfully.
Pan hopped up from under the window sill and into the room.
"Pan I told you to go home!" Gohan said sternly
"You also said WE found the stone when it was clearly ME!" Pan retorted
Gohan changes the subject quickly
"Yes…..well……Dad, do you know what it is?"
"No idea, if Kami was still around I'd suggest you ask him but he merged with Piccolo……" Goku replied.
"It's possible that Piccolo would know!" Gohan suggested
"Who's Kami?" Pan asked
"Kami was the guardian of Earth before he merged with Piccolo" Goku replied "Here hold on, I'll get us there faster"
Goku placed his index and middle fingers on his head. Gohan put a hand on his fathers shoulder as Pan grasped his other hand. In a flicker they were standing on Kami's lookout.
MR. Popo just happened to be watering the trees at the time when Goku, Gohan and Pan all appeared in front of him.
"Hey Mr. Popo, it's been a long time!" Goku greeted him.
"Not too long…!" Mr. Popo agreed.
"Is Piccolo around?" Gohan asked abruptly
"Oh, he should be around somewhere……" Mr. Popo answered
"Is he here?" Gohan pushed on
"He should be here…." Mr. Popo answered
"Dad, can you sense him?" Gohan questioned his father since he couldn't get anything from Mr. Popo.
"Yeah, he's here….., he's at the door…" Goku replied, smiling
Gohan wheeled around to see Piccolo standing in the arch way.
"Piccolo!" Gohan shouted happily
"Gohan, I thought you'd grown a lot when I last seen you but now…now you're a man!" Piccolo said.
"I'm still stronger than you big green! Gohan replied
"Dad show him the stone!" Pan said, pulling on his fathers training bottoms.
"oh…right….here, do you know what this is?" Gohan asked showing the stone to Piccolo, similar to how he had shown Goku.
Piccolo noticed the wobbling immediately.
"I….I'm sorry Gohan, I have no idea what this is….." Piccolo said sadly
"Wait…isn't that the dragoon stone?" Mr.Popo interrupts them
"You know what this is?" Goku asked
"Yes, it's a portable chamber….sort of like a mobile hyberbolic time chamber if you will…." Mr. Popo answered
"Hey, if we could open this we might be able to train in it! Gohan suggested
"How do we open it?" Goku asked as he tapped the stone
"Why don't we try putting it on the door, there's a hole on the hyperbolic time chamber door, we could put it there!" Piccolo recommended
Goku, Gohan, Pan and Piccolo are standing out side the hyperbolic time chamber door. Piccolo pushes the shiny blue stone into the slot. Blue snaps of electricity pulse through the door. Piccolo places a hand on the door without any pain.
"So far so good!" Piccolo growled
"Go ahead! Open it already!" Pan shouted
Piccolo half smiled, the last time he'd been spoken to like that was when he had been training Goten and Trunks. He pushed with his right and it swung open to reveal an endless blue.
"That's a good sign, last time we tried to open this thing it wouldn't budge!" Piccolo explained.
Goku peered in.
"It looks like the hyperbolic time chamber but more……blue!" Goku exclaimed
A ki balst came flying out of the chamber and explodes, taking an arm off Piccolo.
"UGH" Piccolo gasps as a teenager steps out of the chamber.
HE turns to face Goku and Gohan, his long brown hair whipping around as he does so. His bulging muscles tighten with in his dark blue full body cloth which covers all except the neck and face as he turns and connects with a fist to the face of Gohan. Gohan stumbles backwards leaving him open to a spin kick from the teen. Goku remains unchanged by the recent beating of his son.
"Who are you?" Goku asked
"Not that it matters, but I am Aplat!" the teen replied in a low unused voice.
"You're a saiyan…." Goku told him
"Maybe I am, I'm not really sure who I am, I gave myself my name from the first thing I remember saying…I remember very little, but I do remember my first by the urge to fight and destroy….now I will show you that urge!" Aplat explained.
Before Goku makes a move Gohan smashes his foot into the side of Aplat's face. He stumbles off balance and Gohan sees an opening for a punch but Aplat grabs the fist and from the palm of this other hand he fires a long purple beam. Gohan pulls his fist out of Aplats grasp then crosses them as he bends his knees, in an attempt to block the beam. Finally Gohan manages to punch the beam away but only to find that he's ended up outside and above Kami's lookout.
Goku still hasn't made a move as Piccolo jumps up behind Aplat and wraps his arms around his opponents upper body to prohibit him movement but Aplat easily escapes by employing a energy field, sending the namek through the walls of the lookout.
Aplat turns his attention back to Goku.
