"I know one way to stop him, Kakkarot," Vegeta says.

"How?" Goku asks.

"We go Super Saiyan 4," Vegeta says.

"Gotcha'," Goku says.

The two then go Super Saiyan 4. "HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!" they both yell.

"Just be sure to not use any beams on him. He can copy them and turn them black and 10x stronger," Goku says. He's now in his adult form because he's Super Saiyan 4.

"I know, Kakkarot. I heard him," Vegeta says, "Good thing he already knows this." Vegeta fires a Big Bang Attack at dark TRUNKS. dark TRUNKS gets hit and takes some damage. The fight begins. They fight for a good time, but dark TRUNKS is slightly stronger than them.

"The only thing that can beat us is the Kamehameha," Goku says, "Good thing he does know it."

"Oh?" dark TRUNKS asks, "You used it while I was transforming.

"What?!" Goku asks.

"Dark Kamehameha," dark TRUNKS says as he takes out both of them in one shot.

dark TRUNKS laughs evilly after beating them. But in the background, you can slightly hear Goku and Vegeta saying "Fusion-Ha!" in the background. A flash of light is seen and dark TRUNKS turns around.
