OP-17 The World's Strongest Warriors
OP-17
The World's Strongest Warriors
Yonko, Giants, and the debut of Rocks D. Xebec — the most ambitious One Piece Card Game set since launch.
OP-17: The World's Strongest Warriors is the One Piece Card Game's 4th Anniversary booster set, releasing in Japan on August 22, 2026. It covers the Elbaf arc and the four original Emperors — Whitebeard, Shanks, Kaido, and Big Mom — and introduces the game's first Treasure Rare rarity and first-ever Super Leader Parallel. We have Japanese boxes available now on pre-order at Japanese TCG Supply.
Set at a Glance
All 6 Leaders
Every leader slot is now officially confirmed via Bandai card-reveal videos, covering all five colours plus Black. This is the first time Rocks D. Xebec has ever appeared in the TCG.

Chase Cards
OP-17 packs in more premium treatments than any previous One Piece set. Below are every confirmed special card — the Super Leader Parallel, four Yonko Manga Rares, the full Special Art Reprint SP lineup, and the Four Emperors Gold SPs. These are the cards driving collector demand ahead of the August 22 Japan release.
Why OP-17 Is the Set of the Year
For collectors, OP-17 stacks several firsts at once. The Super Leader Parallel is the game's first ever Manga Rare treatment on a Leader card. The Treasure Rare is a brand new rarity above SEC — just one per set, rarer than anything the game has produced before. The Pirate Crew Super Parallel reportedly pulls rarer than standard Manga Rares, and the four Yonko Manga Rares — Whitebeard, Shanks, Kaido, Big Mom — in a single anniversary set is the kind of collector lineup that drives sustained demand long after release.
For players, six strong leaders across all five colours gives every archetype something new. Rocks D. Xebec's tribal payoff makes Blue genuinely threatening, and Black Luffy's Elbaf framing opens up new high-cost strategies that didn't exist in OP-16. The Japanese version is 6 cards per pack - structurally different from the English 12-card format, with distinct pull rate dynamics that make Japanese boxes the collector choice.
