!SPOILERS!
Vegeta actually never actually becomes Super Saiyen 3, He does however become Super Saiyan 4 by using a 'Blutz Wave Amplifier' near the end of Dragon Ball GT
!SPOILERS!
No Notice That You said Gotenks (The Fusion Between Goten and Trunks) if by this you mean Strongest Fusion than your still wrong Gogeta is the strongest fusion (the fusion between Goku and Vegeta. their second fusion. the good side to your question though is that Gotenks is the second strongest fusion because the fusion actually can allow a Super Saiyen 3 form (Gogeta allows a Super Saiyen 4 Form). and incase your wondering Vegeta and Goku's Second Fusion the first one was Veggito.
Vegeta could pass super saiyan 2 but he never trained to like Goku did. He used the Bluts Wave to become a great ape and then golden ape because he needs the artificial power because he lost his tail. vegeta didn't achieve super saiyan 3 he skipped it and went super saiyan 4 using blux waves but you can play as ss3 vegeta in the video games
yes he can and so can broly and vegeta
vegeta super sayain 3 because he blast people
Never. :(
goku super sayayin 3
Only in the the video games
you can't because vegeta never got to super sayian 3 he skiped it
for one there is no such thing as ssj3 vegeta but if he did he will totally be stronger than goku
no. but he goes super saiyan 4 in dragon ball gt
Many dragon ball fans say that Goku's power level is higher, but Vegeta's and Goku's power level is equal. If there was a unbalanced power level, they wouldn't have been unable to fuse in GogetaActually, your max power levels don't have to be exactly the same. The stronger fighter just has to lower hi power level to match that of the weaker. I am pretty sure that Goku's power level is higher, as he defeated Vegeta in the beginning, was the first to become Super Saiyan, the first to become Super Saiyan 3, the first to become Golden Oozaru, the first to become Super Saiyan 4, you catch my drift. Also, Vegeta and Goku were only evenly matched when Vegeta was in his Majin state.
He ascends past it. He might be able to, but there is no reason to since it uses a lot of kai (which may be why he can't become one) and he is already a Super Saiyan 4.
