One Piece: Super Grand Battle! X Scan Shows Sabo and Amiibo Crossover
The latest One Piece: Super Grand Battle! X scan shows off Sabo as a playable character which you can unlock at the title screen by inputting certain button commands in order.
Over at the bottom there’s a very interesting collaboration between One Piece characters and Amiibo. Only players who have a Japanese New 3DS will be able to get these costumes sadly since the regular 3DS does not support Amiibo yet.
