Dragonball Xz, dark TRUNKS Saga, Episode 8 - "The Debate - To Kill or to Save?"
Everyone is training at the Lookout after beating dark TRUNKS.
"We need to find a way to save Trunks," Gohan says.
"I don't know why you three always want to save the bad guys. You make me sick that you are Saiyans," Vegeta says.
"But, Vegeta, he's your son," Goku says.
"Fuck that, Kakkarot, he's the bad guy now and we need to kill him!" Vegeta yells.
"No, we are going to save Trunks. I know it's possible to beat dark TRUNKS without doing that," Goku says.
"Screw that, we'll fight over it!" Vegeta says. "RAWR!" he yells as he goes Super Saiyan 2.
"Vegeta, you will always be the same," Goku says. "HA!" he yells as he goes Super Saiyan 2.
They have a long fight and are evenly matched.
"I know you are stronger than that, use your full power. You always go easy on your opponents," Vegeta says.
"But then I'll beat you without trying," Goku says as he instantly goes Super Saiyan 3.
Goku then punches Vegeta once and knocks him out of Super Saiyan.
"Your power is such a waste on such a weakling on the inside," Vegeta whispers.
"That's decided. We are going to 'save'!" Goku yells.
