One a grassy plain, a fight is happening. Literally this pink pony has incapacitated Krillin, Tien, Piccolo, and Yamcha is on the brink of death. Goku, Vegeta and Gohan are the only ones standing. Slightly injured from the attacks from this pink pony. It was just beating on some harmless civilians, but after Vegeta kicked it in the face very hard. It suddenly snapped. And it's just smiling. It's expression never changing

Vegeta: "Damnit Kakarot! How is this pink pony keeping up with us?!"

Goku: "I don't know Vegeta, but show how this things power level is increasing every second! This might be the biggest threat we have ever faced..."

Then Goten and Trunks perform the fusion dance and turn into Gotenks

Gotenks: "Don't worry dads! We got this!"

They boost towards the pony at incredible speeds
