Galaxy Mode acts as the game's story mode, featuring a series of challenges for each version of every character. A series of battles progress in difficulty until the final battle, with a difficulty level of "Ultimate"; these tasks range from defeating a series of opponents while the player character's health drops to defeating a powerful opponent with 1 HP. Clearing stages earn special attacks or power-ups for the chosen fighter along with bonus items that can be viewed in the Gallery such as artwork. Fully-completing a Galaxy for one character earns the player a Dragon Ball; as in the show, seven must be collected before the player can call on Shenron for a wish, rewarding the player with additional unlockables of their choice. Battle Zones serve much of the same purpose as Galaxy Mode, with the player progressing toward a boss character throughout each Zone. Stamps can be earned by performing specific tasks, such as giving the player character a handicap or refraining from performing special attacks, rewarding the player with more bonuses.
A bonus 30-minute OVA is included with the game: Dragon Ball: Plan to Eradicate the Super Saiyans . Originally released in 1993, it has been completely reanimated, and watching it unlocks the main antagonist, Hatchiyack, as a playable character.
