Unlockables

  1. Unlocking Extra Costumes- Straw Hat Pirates

    All Straw Hat characters but Vivi start with their 1P and 5P costumes, and in Robin's case the 4P as well. In general, 4P costumes will be found first, while 2P costumes appear later in the game and are more complicated to get. Any costumes unlocked in Adventure mode will be usable in every other mode.

    In unlocking Luffy's 2P costume, make sure not to fight Crocodile until after you have travelled to Jaya and are prompted to finish Crocodile before proceeding, or your game will end at the Crocodile fight.

    An easy way to beat Ace(Trace) with Chopper in the Graveyard of Ships is to use Chopper's "Health" attack (Jump+O) non-stop. Beware of rolling bombs.

Glitches

  1. Removal of Opponent's Supports

    This is for battles where the CPU starts off with multiple support characters helping them. If you open the disc tray/cover as soon as "FIGHT!" appears on screen, you can battle as normal without their supports interfering. When the battle is finished, you need to close the disc tray/cover to let the game resume.

    NOTE: This does not cancel permanent effects, environmental changes, or supports that are summoned during the battle.
