An update for One Piece: Super Grand Battle! X scheduled for this winter will add amiibo support to Bandai Namco’s fighting game. If you use a Mario amiibo on the game you’ll unlock a costume that dresses Luffy up as Mario.
A screenshot shows Sanji dressed like Fox and Zoro as Link. These costumes are unlocked with Fox and Link amiibos, respectively. The game also supports the Luigi amiibo which also gives Luffy a costume according to an earlier report.
One Piece: Super Grand Battle! X is out now in Japan and a demo for the game is also on the Nintendo eShop.
