Past

Fischer's x One Piece
The Fischer's Pirates land on Carvador Island, surprised they haven't arrived at Dressrosa. Upon entering the town, they run into Johnny and Yosaku, and after a bit of confusion about them being in the New World, are informed of the island's love of the One Piece Card Game. Seeing the One Piece characters refer to themselves as cards confuses them, and they're informed by Mr. Kuromaku that due to the release of the One Piece Card Game in Japan, they brought them into their world as well.

After getting over their shock, Fischer's are informed by the bounty hunter duo that they may as well get used to the cards, since the Log Pose lock on time is one year. Worried about Luffy reaching Laugh Tale before they can meet him, the Fischer's crew is informed that there's also an island-wide tournament that day, with the winner getting an Eternal Pose pointing to Dressrosa. Relieved, the pirates decide to enter the tournament, buying their first packs of cards.

Once the tournament begins, Dama defeats Yosaku and Masai defeats his opponent. Silk Road realizes that Ndaho forgot to register, and vows to become the One Piece Card Game King.

Some time later, the preliminaries end, with 16 participants advancing to the second round. The tournament is split into A and B blocks. In the A block, Silk Road defeats Basil Hawkins, Zakao defeats Wapol, Masai defeats Motoki, and Caribou defeats Dama. However, Dama claims that Caribou cheated to win, though he can't be eliminated without proof.

Eventually, the tournament reaches the final match, between Silk Road and Caribou. During the match, the Fischer's Pirates find Coribou looking at Silk Road's cards and stop him from reporting them to Caribou. In a last bid for victory, Caribou attempts to use cards he's hidden with his Numa Numa no Mi abilities, but is stopped by Seastone handcuffs placed on him by Dama. With his cheating stopped, Silk Road claims victory, receiving the Eternal Pose to Dressrosa and ending the tournament.
