Gogeta and Vegito are both fusions of Goku and Vegeta but there are many lore differences between the two in the Dragon Ball Universe
Gogeta will be made available as a new playable fighter in Dragon Ball FighterZ tomorrow, on September 26. His inclusion is mostly in celebration of the semi-recent release of the Dragon Ball Super: Broly movie.
Although both Gogeta and Vegito are fusions between Goku and Vegeta, there are some notable differences between the two. Let's take a look at them.
First off, their methods of fusion are actually quite different. While Vegito is a form that is created as a result of both Goku and Vegeta putting on a single pair of Potara earrings, Gogeta comes about when the same two performs the Fusion Dance.
Initially, the Potara earrings were said to create a fusion between two individuals that would be permanent. However, this has since been retconned to only be a permanent fusion if one of those involved is a Supreme Kai.
In the event that two beings that are not of the Supreme Kai race fuse this way, then the fusion will only last an hour instead. It's currently unknown why Old Kai did not actually know this when he misinformed Goku during the Buu Saga.
As for the Fusion Dance, the form that comes about afterwards will only last for 30 minutes. Complications will arise if both practitioners do not perform it perfectly.
It is said that the Potara earrings are actually more powerful than the Fusion Dance variant. In other words, it is implied that Vegito is actually stronger than Gogeta.
With that said, both Vegito and Gogeta are among the most powerful characters in Dragon Ball lore as of right now. This becomes especially apparent when they power up with Super Saiyan Blue.
Vegito appeared onto the scene when going up against Super Buu and Fused Zamasu. Meanwhile, it was Gogeta that fought against Janemba (during a non-canonical interaction), Omega Shenron (also non-canonical), and Broly.
Both of these fused characters have powers and abilities that can rival the gods of the Dragon Ball universe. Notably, Goku made a statement to Broly that indicated that Broly was actually stronger than Beerus, the God of Destruction for Universe 7. Despite this, Gogeta was able to defeat Broly with relative ease.
Vegito tends to take on more of Vegeta's personality over Goku's. This results in very cocky mannerisms. Because of this, Vegito's fights with Super Buu and Fused Zamasu tend to go on for a bit since Vegito ended up toying with the two.
Gogeta, on the other hand, bears more similarities to Goku's nature. However, Gogeta tends to end fights more quickly compared to Vegito — with the exception of Omega Shenron.
The two fusions appear to have access to unique techniques. While Vegito uses Final Kamehameha and the Spirit Sword, Gogeta has pulled out abilities like Stardust Breaker, Punisher Drive, Stardust Fall, God Punisher, and Big Bang Kamehameha.
So while Gogeta and Vegito are both fusions of Goku and Vegeta, they are, in many ways, fairly different characters. As a result, there are fans that back both of the two fusion warriors.
This is probably enough to justify another slot in Dragon Ball FighterZ for someone that is effectively just Goku and Vegeta in one character.
