ssj4 vegeta

Vegeta then tells Goku that he has the tool he needs to reach Super Saiyan 4, much to Goku's shock. Thanks to Bulma's Blutz Wave Generator, Vegeta transforms into a Great Ape. At first, Vegeta seems to have lost control of himself and begins crushing Goku. However, Vegeta states that he was simply fooling them, and transforms into a Golden Great Ape, and then, a Super Saiyan 4. Everyone is amazed by the overwhelming power the two Super Saiyans 4 have, and Chi-Chi and Bulma have a usual quarrel over whose husband is the best. The two Super Saiyans 4 head off against Omega Shenron, but they are still not powerful enough to beat the fearsome dragon. So, Vegeta suggests that they fuse.
