Gohan's Sparking Episode in Dragon Ball: Sparking! Zero diverges from the Resurrection F Arc and leads into the reveal of Gohan Black.

A DLC pack for Dragon Ball Xenoverse 2 added Gohan Beast as a playable character, and while it takes some time to unlock, it's more than worth it.

How to unlock Future Gohan in Dragon Ball: Sparking! Zero Like every unlockable character in Dragon Ball: Sparking! Zero, you'll be able to unlock Future Gohan via the in-game shop by using Zenny.

Do these to unlock the likes of Caulifa, Future Gohan, and Gogeta (Super). That last one’s especially important if you didn’t pre-order (good for you), and get early unlocks for the character.
