For someone who is obsessed with attain increasingly powerful shift through intense training and solitary density , Vegetawasn’t able-bodied to reachSuper Saiyan 4(arguably the strongest shift inDragon Ballhistory ) on his own , as it wasBulmawho unlocked this top - tier Super Saiyan form , not Vegeta .

Vegeta ’s power - level progression throughoutDragon Ballis one marked by stemma , sweat , and binge set out with his training to become a Super Saiyan after witnessing two other Saiyans accomplish the transformation before he could ( those two being Goku and Future Trunks ) . After a recollective stretch of time training on a uncongenial world , combat deadly asteroid reigning hell upon him , Vegeta finally institute the strength he needed to unlock Super Saiyan . After increasing his power enough to finally reach Super Saiyan 2 , Vegeta ’s next major force - up would be mark by hisascension to Super Saiyan Godwithin the continuity of Dragon Ball Super . While Goku unlocked this transformation first , he needed the help of an energy - communion rite whereas Vegeta got there all on his own . alas , all the hard study that Vegeta put into earning his former transformations was not seen with Super Saiyan 4 – in fact , Vegeta did n’t really do anything at all .

Bulma Did All the Work in Unlocking Super Saiyan 4 for Vegeta

InDragon Ball GTepisode 55 ( written by Atsushi Maekawa , directed by Osamu Kasai , produced by Toei Animation ) , Goku and Pan are battling the unattackable Shadow Dragon yet , all while Vegeta sits at family , thinking about how Goku has vastly widened the gap between theirpower level by reaching Super Saiyan 4 . However , after expect back on his liveliness and recognize how hard he ’s worked to be as strong as he is today , Vegeta decided that he was n’t vex by the fact that Goku is better than him anymore , and that he was happy with simply seeing how warm he could become without equate himself to Goku . But , that transfer completely by the end of the sequence when Bulma allege she could make him a Super Saiyan 4 , no grooming call for – and she already examine she can commit it off .

Back inGT ’s Baby Saga , Bulma was mind - see into helping the coalition of Baby and Vegeta ( who was known as Baby - Vegeta ) become a Golden Great Ape to beat SSJ4 Goku . As sports fan already knew at the meter , becoming a Golden Great Ape and then curb one ’s mind in that form is how aSaiyan becomes a Super Saiyan 4 . Baby - Vegeta did n’t become a Super Saiyan 4 because the presence of Baby within Vegeta would n’t leave for the transformation , but the motorcar Bulma built to harness and heighten Bruits Waves could be used again on Vegeta alone – and this time , that Golden Great Ape translation would result in a Super Saiyan 4 as Vegeta would n’t have an alien parasite block it as well as the fact that he already proved inDBZthat he can control his Great Ape form with repose .

What ’s the most interesting aboutVegeta ’s shift into a Super Saiyan 4is that he did n’t have to increase his power level at all to get there . Every other time Vegeta needed to unlock a newfangled form inDragon Ball , he had to advertize himself harder than he ever had before , but in this case , that power was within him all along , it just needed to be brought out with Bulma ’s twist – and that ’s why it ’s true thatVegetanever really unlockedSuper Saiyan 4,Bulmadid .
