As you play through the various modes and Quests found in Dragon Ball FighterZ, you will earn Zeni, the currency found within the Dragon Ball Series and this game too. With this money, you can purchase various things found within the game's Shop. At the Shop, you can buy a number of items to add to your personal game. The most intriguing thing you can buy are the fighters of SSGSS Goku and SSGSS Vegeta, but you can also purchase things like Titles, Lobby Chibi Avatars, Alternate Chibi Avatar Skins, and Stamps.
