Goku is the person that can turn SSJ3. In fact he is the only person that can turn SSJ3 in dragon ball z. Gotenks can also transform into SSJ3 but i dont know if u can really include fuzed characters, and more recently in the raging blast games vegeta, and Broly can also but they never did in the anime, Although it is kind of logical seeing how Vegeta can go SSJ4 and Broly is the "Legendary Super Saiyan". So can vegeta and broly
vegeta
Babidi goes into Vegeta's mind and takes control of Vegeta, which turns Vegeta evil (Majin).
This ain't true that you muast be dead
No broly isn't the strongest. It was mentioned in gt that Goku was the strongest saiyan who ever lived. Th is was even stated by omega shenron. In addition ssj3 is way stronger thann lssj. Even the author of dragon ball stated broly cant go over lssj because it would destroy the planet. Broly can't control his power. So goku is the best
sorry , but there is no ssj3 vegeta, but there is a ssj4.
No.
Yes.
none
no, he never turned ssj3 in the series BUT in dbz raging blast game he turned ssj3 in wat if saga (its not just vegeta turned ssj3 in raging blast BROLY turned ssj3 too ) =D
they are about the same but goku is a tiny bit stronger but not by much
you need to obtain 20 stars in dragon battle collection, and buy the secret Battle 47 (What-If Stories) - beat this battle to unlock ssj3 vegeta (it is a separate character from vegeta as it is not canon)
for one there is no such thing as ssj3 vegeta but if he did he will totally be stronger than goku
from google.com
It is confirmed that it is SSJ3 Vegeta.
you can unlock goku and vegeta as ssj3's but dbrb and drbr2 don't have ssj4
Of course goku's power level is higher than vegeta considering the fact that he even reached a high level (SSJ3) which vegeta can't do.
