Dragon Ball Z: Supersonic Warriors/Teams

In the game's Z Battle mode, you can battle freely with all of the characters you've unlocked. Unlocking characters can be done by going to the game's Shop in the Options and spending points, which are earned by either battling in Z Battle mode or finishing a story in Story mode. Fighting with a certain team setup can get you extra points in Z Battle mode, making unlocking characters an easier and quicker task.
