Dragonball Xz, dark TRUNKS Saga, Episode 17 - "The Super Dark Saiyan Defeated"
dark TRUNKS flys back after getting kicked in the face. A dark aura engulfs him suddenly like before.
"Shit," Gogeta says. His fusion is almost out of time. Just before he can charge a Big Bang Attack Times 1000, the fusion wears off.
The aura explodes and dark TRUNKS is sitting there, in his original form.
"You beat me again...not again," dark TRUNKS says as he flys off.
"Heh, we...won," Goku says as his Super Saiyan 4 wears off and he collapses.
"Moron," Vegeta says as he picks up Goku and flies off to the Lookout.
