Combat between Goku and an enemy takes place throughout much of the game at various opportunities. Combat continues until either Goku or the enemy is defeated, or until one of the combatants successfully runs away. If Goku is victorious, he earns experience points for defeating an enemy. If Goku loses, the game is over and the player may continue from the most recent save.

- The number of stars in the Dragon Ball at the top of the card (in green) determines the power of the card. The competitor with the higher number of stars gets to attack. If two cards with the same number of stars appear, the attacks cancel each other out. There is one single exception to the power rule; Goku may attack if he has a one star card and it is pitted against an opponent's seven star card.
- The square in the middle of the card (in yellow) indicates what action will be taken by the player whose card has the higher power. The possible actions are listed below.
- The number presented on the bottom of the card (in blue) indicates the speed of the participant. If the speed of the defending participant is higher than the speed of the attacker, the defender may dodge the attack and escape without damage. The higher the speed is, the greater the chance of successfully dodging. Dodging an attack is not guaranteed.
