he wanted to surpass goku in power
Gogeta, the fusion of super saiyan 4 Goku and Vegeta.
Vegeta turns super sayian in episode 59 of Dragonball gt
Never. :(
When he was fighting Androids 19 and 20.
Kid Buu - 720,000,000 Bebi - 4,000,000 Mature Bebi - 30,000,000 Bebi Vegeta - 475,000,000 Bebi Vegeta 2 - 700,000,000 Super Ape Bebi Vegeta - 2,400,000,000 Vegeta - 150,000,000 Super Vegeta - 300,000,000 Super Vegeta 4 - 2,300,000,000 vegeta would win because kid buu isn't a match and super ape Bebi (yes its Bebi in other places) vegeta would be not a match because vegeta would also turn SSJ4 ape vegeta so...yes vegeta
He becomes a super saiyan a few episodes after planet namek was destroyed
Super Vegito is the fusion of Goku & Vegeta when they turn Super Saiyan and then they merged together by wearing the Potara Earrings
episode 129
Vegeta becomes super sayian 2 when he doesn't kill Majin buu. When he came back to help goku defeat super buu.
Vegeta turns Super Saiyan by not caring if he became a Super Saiyan, and became angry, triggering the Super Saiyan form in the English dub, in the Japanese dub, it was because he allowed his heart to become pure evil. It was not because of Bulma at this time.
No one will go any further because Dragonball is over.
When him and Vegeta were training in The artificial gravity chamber.
