One Piece: Grand Battle Hints

Instead of holding L and pressing A + X to use a random clone-clone attack, try
the following moves to transform instead. By doing this, you can use strategy
instead of luck for which character you will transform into.

Mr. 7: While holding L, press A(4), X.
Mr. 8: While holding L, press A(3), X.
Mr. 9: While holding L, press A(2), X.
