Dragon Ball Super has introduced all-new combat transformations and even more powerful characters to Akira Toriyama's perennially popular Dragon Ball franchise, including new directions and plateaus for longtime protagonist Goku. Among these was combining Goku's inherent abilities as a Saiyan with divine energy to trigger a transformation into Super Saiyan God.
Later in Super, Goku and Vegeta would revisit their original fused form, Vegito, through the use of the Potara earrings, with the composite warrior far more powerful than he had been in his Dragon Ball Z debut. With both of these powerhouses featuring prominently in Super, the question stands: which one is stronger?
Super Saiyan God was discovered during Dragon Ball Super's first story arc. Goku and the Z Fighters learned that if five Saiyans funnel their energy into a sixth Saiyan, the combined energy would cause the recipient to transform in a whole new way. A warrior in this heightened state grows stronger but especially sees a preternatural increase in defensive ability, able to sense incoming blows and gracefully evade them. As Goku grew further accustomed to the combat transformation, he learned he could use its energies to immobilize and pacify targets, as seen when he used the form against Broly in the anime film Dragon Ball Super: Broly.
Vegito made his debut in DBZ, with Goku and Vegeta using the Elder Kai's Potara earrings to temporarily fuse together into a formidable composite fighter and combat Majin Buu after absorbing Gohan Piccolo and Gotenks. While Vegito was only seen transforming into a Super Saiyan in DBZ, by Super he could transform into a Super Saiyan Blue as he battled against the villainous Future Zamasu and Goku Black. And while Super Saiyan Blue Vegito was nearly capable of destroying the rogue Supreme Kai trainee from Universe 10, the fusion wore off before Vegito could finish the job, leaving the Z Fighters to scramble for omnipotent reinforcements and save the day.
It's that time limit that would be Super Saiyan God Goku's only hope in a fight against Vegito, no matter what form the fused Saiyan took. In terms of pure punching power, Vegito is one of the strongest characters in the entire Dragon Ball franchise and Goku wouldn't stand a chance in virtually any conventional engagement. Goku may be able to use Super Saiyan God's abilities to temporarily immobilize or pacify an attacking Vegito, but this would only buy him time to hopefully cause the fusion to wear off. And with Vegito possessing all of Goku's techniques and strategies, he would likely know what the Super Saiyan God is up to before Goku can react himself.
Vegito is far more powerful than Super Saiyan God Goku in terms of a physical battle, and it isn't even a contest. While a Super Saiyan God possesses esoteric, mystical abilities that no other Saiyan combat transformation has been shown to demonstrate, Vegito could theoretically transform into a Super Saiyan God himself as he is capable of going even further with Super Saiyan Blue. That means Vegito will likely be the one to emerge victorious from a potential showdown and win quite handily. For all his godly powers, Super Saiyan God Goku would be outclassed in virtually every way.
