Tarble is the same age as Gohan in this story.
Dragon Ball Z: The Rise of Malevolence
Episode 005: The Five-Star Ball
The heroes, in their spaceship, had made themselves at home. Trunks had revealed himself as an inventor, and Pan had convinced Uub to act friendly toward Trunks. Yamcha was practicing his Wolf Style techniques at all times, and Trunks was working on a project.
"Pan, thanks for talking to Uub," Trunks said.
"It was nothing. We need all the help we can get to find Gohan," Pan said.
"here, meet Giru, my new invention. He can help you in battle, find Dragon Balls, and do almost anything," Trunks revealed, showing his "project" was a small white robot with a red eye.
"Oh, he's so cute. Thanks, Trunks!" Pan said, picking up Giru, who started beeping.
"DRAGONBALL DETECTED," Giru said.
"Let's go tell Uub and Yamcha," Trunks said as they went to talk to their friends.
Hunter Spaceship
The King had summoned, Gohan, Tarble, Raditz, and Vegeta to his throne room.
"Go to Planet Terra-9 and find the Dragon Ball," the King ordered.
"Yes, sir!" they all said before getting into Space Pods and shooting down to the desert planet below.
Planet Terra-9, Unknown Desert
The Hunters searched for the Dragon Ball, while the Resistance Members landed and did the same, Giru leading them. Both groups met each other and Uub, Yamcha, and Pan looked on in shock when they saw Gohan dressed in Hunter Armor, standing beside Tarble and Vegeta.
"Gohan?" Uub managed to say.
"You shouldn't have come here. Now, we have to kill you," Raditz said before he moved to attack.
"Raditz, forget them. Go find the Dragon Ball," Vegeta ordered as the long-haired Saiyan nodded and left.
"Gohan, Tarble, destroy them!" Vegeta ordered.
"I don't know if I can destroy Uub, Pan, or Yamcha," Gohan said.
"If you can't then I will!" Tarble said before charging at Yamcha, pounding him around brutally.
Tarble kicked Yamcha into the sky and kicked him down. Yamcha sprung into the air and struck wildly at Tarble pushing him back before shooting a beam of blue energy at him, blowing him into the side of a mountain.
"Now you've made me mad!" Tarble shouted before swiftly punching Yamcha around, placing a hand on his stomach, ready to skewer him on a wave of energy.
"Stop it!" Gohan shouted before tackling Tarble. In the struggle, someone shot a blast of energy at them, hitting Gohan instead of Tarble.
Gohan looked up and, shocked, saw Uub had fired it, no look of remorse or anything.
"Uub, why did you shoot Gohan?" Pan asked.
"That's not Gohan. It may look like him or sound like him, but it isn't him!" Uub said.
"Enough talk, let's end this!" Vegeta said as he charged at Uub and Pan, punching both before kicking them to the ground.
Trunks shot a blast of energy at Vegeta and the Saiyan Prince pounced. In mere seconds the Prince of Saiyans and inventor were locked in battle. Uub attacked Gohan wildly, but Gohan was reluctant to fight his friend. Tarble appeared and knocked out Yamcha in one strike, fighting with Pan.
"MUST PROTECT PAN," Giru said before hitting Tarble with a missile, knocking him out.
"Nice shot," Pan told the robot.
Meanwhile, Raditz searched and ransacked a nearby area, destroying rocks and small huts to find the Dragon Ball. Zarbon, however, had found it and was walking back to his ship when he encountered Raditz.
"So, Frieza's lapdog went away long enough to do me a favor. Thanks, now hand over the Dragon Ball," Raditz said.
"I don't think so, cretin," Zarbon said before, in a flash, brutally attacking Raditz with a flurry of kicks before launching him to the side.
Zarbon teleported in Raditz's way and punched him before doing a flip and kicking him to the ground. Zarbon charged a blast of energy in his hand, ready to defeat Raditz.
"Any last words, monkey?" Zarbon asked.
"I hope you burn in..." Raditz started before the blast was fired at him.
Gohan and Uub were locked in a fight, but Gohan finally punched Uub, hitting him in the jaw and launching him into a rock. Uub sprung out and used his Thousand Flaming Fists technique, injuring Gohan. Uub charged up a sphere of energy in his hand, ready to shoot a beam, but Vegeta hit him with a Galick Gun. Uub fell to the ground, wounded. Vegeta moved to attack Pan, but Gohan blocked him.
"Vegeta, don't do it. This is my sister, Pan," Gohan said.
"Fine, but tell her to stay away from the Dragon Balls, we need them," Vegeta said.
"Why?" Pan asked.
"We have our reasons," Vegeta said. Suddenly they heard a scream.
"What was that?" Pan asked.
"Raditz!" Vegeta said as the few conscious people ran over to the scream's source.
Raditz, his armor destroyed and his chest bloody, was lying in a pool of his own blood, dying slowly. Zarbon, uninjured, floated above him, holding the Five-Star Dragon Ball in his arms like a mother would a baby.
"Zarbon!" Vegeta shouted as they saw Frieza's commander.
"Prince Vegeta, always a pleasure to be in the presence of such arrogant royalty," Zarbon said, mockingly bowing.
"What did you do to Raditz!?" Gohan asked.
"He got in my way, and I followed orders. Lord Frieza wants you all dead. I'll do you a favor, though. I'll forget I saw any of you. I'll be taking my leave," Zarbon said before speeding away.
"We have to follow him!" Gohan said.
"You, get your friends on your ship and follow us, we're going to destroy Zarbon," Vegeta said to Trunks and Pan.
The Resistance and Hunters split up and boarded their respective ships, following Zarbon.
