Bandai Namco Taiwan accidentally leaked the latest trailer for SGSS Vegito for the game Dragon Ball Fighter Z. He is a new character that will be added as DLC in the near future.
As some people might know already, Vegito is the fusion between Goku and Vegeta when they put on the potara earrings. He first featured in the Buu saga in Dragon Ball Z, but made another appearance in the Dragon Ball Super Future Trunks saga against Merged Zamasu.
This version of Vegito is strong because he can turn Super Saiyan God Super Saiyan. You can shorten the name to just Super Saiyan Blue which is much easier to say. The character will be added in the near future as DLC in Dragon Ball Fighter Z along with Merged Zamasu as well who is from the same saga.
Anyway, you can look at the new character trailer posted down below. No release date has been announced for the DLC yet, but he should be appearing in the video game very soon.
