Updated on 09/21/2026

One Piece OP17: The World’s Strongest Warriors is the major 4th Anniversary Booster Set for the One Piece Card Game. The expansion has now been released, and many details that were still unknown before the Release have been officially confirmed. OP17 brings together the Straw Hat Pirates’ new Elbaph arc with the Rocks Pirates, the Four Emperors, and several especially elaborate collector cards.

That’s why Players and Collectors will find OP17 much more interesting than the first announcements suggested. Bandai puts Rocks D. Xebec, Loki, Monkey D. Luffy, Shanks, Kaido, Charlotte Linlin, and Edward Newgate in the spotlight, among others. The set also includes new cards featuring the Straw Hat Pirates in Elbaph outfits, special 4th Anniversary artwork, and a first-ever Super Leader Alt-Art.

In this updated overview, you’ll find all the key information about One Piece OP17 The World’s Strongest Warriors: Release, set size, new Leaders, the Rocks Pirates, Elbaph cards, special Alt-Arts, and the OP17 product currently available at cardcosmos.

What is One Piece OP17 The World’s Strongest Warriors?

OP17 is the seventeenth main set of the One Piece Card Game and also the major anniversary set celebrating the TCG’s fourth birthday. The full English name is The World’s Strongest Warriors.

The title now clearly reflects the actual contents. The set brings together some of the most powerful characters in the One Piece world and combines several major themes: the Straw Hats on Elbaph, the legendary Rocks Pirates, and the Four Emperors.

The Prerelease for the international English version took place on August 21, 2026, followed by the regular Release on August 28, 2026. The Japanese edition came out earlier in August and remains especially interesting for Collectors who collect One Piece cards in Japanese or prefer sealed Displays.

The updated set size is important: smaller figures were circulating before the Release. Bandai now officially lists the English version as having 131 + 4 card types. Parallel cards and alternative artwork also mean that the actual number of collectible variants is significantly higher.

The Six New Leaders in OP17

Six new Leaders are coming to the One Piece Card Game with OP17. They represent some of the series’ biggest names:

• Edward Newgate
• Shanks
• Rocks D. Xebec
• Kaido
• Monkey D. Luffy
• Charlotte Linlin

This selection perfectly illustrates the name The World’s Strongest Warriors. Whitebeard, Shanks, Kaido, and Big Mom are among the best-known powerhouses in the One Piece world, while Rocks D. Xebec represents a central part of the historical pirate era. Luffy connects this legendary past with the current story.

Rocks D. Xebec and the Rocks Pirates Take Center Stage

One of the main themes of OP17 is the Rocks Pirates. Bandai shows not only Rocks D. Xebec himself, but also numerous members of his legendary crew.

These include Edward Newgate, Kaido, Charlotte Linlin, Shiki, Gloriosa, Captain John, Wang Zhi, Miss Buckingham Stussy, Streusen, and other characters.

This creates a new cohesive deck theme for Players. For Collectors, what’s especially interesting is that Bandai is also featuring the Rocks Pirates in special 4th Anniversary Alt-Arts.

Elbaph: The Straw Hat Crew Gets New Cards

OP17 is also one of the first major sets to bring the Straw Hat Crew’s current Elbaph look prominently into the One Piece Card Game.

New cards featuring Monkey D. Luffy, Roronoa Zoro, Nami, Usopp, Sanji, Tony Tony Chopper, Nico Robin, Franky, Brook, and Jinbe in their Elbaph outfits were officially revealed.

Loki, the former king of the Warland Kingdom, is also one of the set’s central characters and appears as an important card in OP17. This connects The World’s Strongest Warriors’s current manga themes with historical legends such as the Rocks Pirates.

The First Super Leader Alt-Art: Monkey D. Luffy

One of the biggest new features of OP17 is the introduction of a Super Leader Alt-Art. This especially high-quality variant is given to Monkey D. Luffy OP17-079.

Bandai describes the Super Leader Alt-Art as a particularly elaborate version of a Leader card, featuring artwork from the original One Piece manga. For Collectors, this Luffy card is therefore one of the set's clear highlights.

Leader cards are especially popular in the One Piece Card Game because they remain visible throughout play while also having strong collector appeal. An additional premium tier above the familiar Leader Parallels makes them even more appealing.

Super Alt-Arts of the Four Emperors

Another major collecting theme is the Four Emperors. OP17 prominently features Edward Newgate, Shanks, Kaido, and Charlotte Linlin side by side, with several of these cards receiving especially high-quality alternative designs.

For Collectors who build their Binder collections around crews, emperors, or legendary pirates, this part of the set is one of the most interesting.

Kaido illustrated by Keisuke Itagaki

One of the most striking special cards features Kaido in a newly drawn illustration by Keisuke Itagaki, creator of the Baki series.

These artist crossovers are especially exciting in the One Piece Card Game because they depict familiar characters in a very different art style. The Kaido card clearly stands out from regular set cards and is one of the special collector designs in OP17.

4th Anniversary Pirate Crew Alt-Arts

For its fourth anniversary, OP17 introduces special Pirate Crew Alt-Art Cards. Bandai particularly highlights two major groups:

• Straw Hat Crew
• Rocks Pirates

This makes OP17 not just a regular main set, but also a true anniversary product. The special crew artwork visually connects multiple cards and makes them particularly interesting for Binder collectors.

Color of the Supreme King Haki Special Product Cards

Another distinctive card style in OP17 draws on Conqueror's Haki, also known as Color of the Supreme King Haki. These Special Product Cards have their own design and are among the set's premium variants.

This means OP17 offers another distinctive collecting style alongside classic Alt-Arts, Leader Parallels, and the new Super Leader Alt-Art.

Which Secret Rares are in OP17?

The most important regular high-rarity cards include Rocks D. Xebec and Loki. Both characters fit perfectly with the set's two major storylines: Rocks represents the legendary pirate era, while Loki represents the current Elbaph storyline.

Secret Rares are interesting to Players when their effects become relevant in competitive decks. For Collectors, Parallel and Alt-Art versions are the main focus.

OP17 in Japanese or English?

Japanese and English OP17 products contain the same core set, but differ significantly in booster format.

A Japanese Booster usually contains 6 cards, while the English version contains 12 cards per Booster. Both Displays contain 24 packs. This creates a different opening experience, even though the cards belong to the same set thematically.

Japanese OP17 cards are especially interesting to Collectors who like the original language, Japanese packaging, and sealed Displays. English OP17 cards are more practical for many European Players, as the card text is easier to read and can be used in local play.

Which OP17 product is currently available at cardcosmos?

Currently, you can find the One Piece Card Game OP17 The World’s Strongest Warriors Booster Display in Japanese at cardcosmos.

The Japanese Booster Display contains 24 Booster packs with 6 cards each and is especially suitable for Collectors who want to open as many cards and parallel variants from OP17 as possible or collect the anniversary set sealed.

You can find more One Piece products, older sets, and upcoming expansions in the One Piece Card Game Collection at cardcosmos.

What makes OP17 special for Collectors?

OP17 is one of the sets that brings together several collector appeal factors at once:

• 4th Anniversary Booster with anniversary designs
• Super Leader Alt-Art Monkey D. Luffy
• Rocks D. Xebec and the Rocks Pirates
• Straw Hat Crew in Elbaph outfits
• Four Emperors as the central theme
• Kaido artwork by Keisuke Itagaki
• Pirate Crew Alt-Arts
• Supreme King Haki Special Product Cards
• Secret Rares and Treasure Rare

This gives The World’s Strongest Warriors a much stronger visual identity than an ordinary main set.

What makes OP17 interesting for Players?

The six new Leaders and the extensive support for their respective deck themes are especially important for Players. OP17 expands strategies centered around Whitebeard, Shanks, Rocks, Kaido, Luffy, and Big Mom, among others.

Bandai now also offers official Recommended Decks for the new cards. This makes it much easier to assess how the new Leaders and support cards work together than it was before the Release.

For tournament players, this is also important: Bandai states that OP17 cards are legal at participating Local Game Stores starting with the respective Prerelease.

Booster packs or a Booster Display: Which is worth it for OP17?

Individual Booster packs are a good choice if you want to get to know the set first. A Booster Display, on the other hand, is more appealing if you want to open lots of cards from OP17, build decks, or look for parallel cards.

Even with a complete Booster Display, there’s of course no guarantee of a specific Super Leader Alt-Art, Secret Rare, or other chase card. If you’re looking for a specific card, you can supplement Displays and Booster with singles later.

One Piece OP17 is one of the most important sets of the anniversary year

One Piece OP17 The World’s Strongest Warriors is now much more than an announced anniversary set. Since its Release on August 28, 2026, it’s clear just how well Bandai has brought the fourth anniversary theme to life.

Rocks D. Xebec and his crew, the Straw Hats on Elbaph, the Four Emperors, Loki, and several new premium artworks give the set a distinct identity. The first Super Leader Alt-Art of Monkey D. Luffy, the crew artworks, and the Kaido illustration by Keisuke Itagaki make OP17 appealing to Collectors.

For Players, six new Leaders and numerous Support cards bring new deck-building possibilities. For Collectors, The World’s Strongest Warriors offers several distinct chase categories and one of the strongest character lineups in the history of the One Piece Card Game.
