Celebrating 4 Years of ONE PIECE Card Game

OP-17 is a major 4th Anniversary release for the ONE PIECE Card Game.

Rather than focusing on just one crew or storyline, The World's Strongest Warriors brings together legendary characters from multiple generations of ONE PIECE.

The expansion celebrates the past while simultaneously moving the Card Game into the latest Elbaf chapter.

The Straw Hat Crew Arrives in Elbaf

The Straw Hat Pirates make their appearance wearing their Elbaf outfits, giving collectors new versions of the entire crew.

Featured Straw Hat characters include:

• Monkey D. Luffy
• Roronoa Zoro
• Nami
• Usopp
• Sanji
• Tony Tony Chopper
• Nico Robin
• Franky
• Brook
• Jinbe

For fans following the latest ONE PIECE storyline, OP-17 is particularly significant as Elbaf becomes a major theme of the expansion.

Monkey D. Luffy Super Leader Alt-Art

One of the major new premium treatments introduced with OP-17 is the Super Leader Alt-Art.

Monkey D. Luffy OP17-079 receives this special treatment featuring artwork taken from the original ONE PIECE manga.

Unlike a regular Leader Alternate Art, the Super Leader Alt-Art is designed as an especially premium version of the Leader card and is one of the major collector features of OP-17.

The Rocks Pirates Enter the Battle

One of the biggest attractions of OP-17 is the arrival of the legendary Rocks Pirates.

The expansion features Rocks D. Xebec alongside an extraordinary lineup of characters connected to the infamous crew.

Featured characters include:

• Rocks D. Xebec
• Edward Newgate
• Kaido
• Charlotte Linlin
• Shiki
• Wang Zhi
• Captain John
• Gloriosa
• Miss Buckingham Stussy
• Streusen
• And more

Rocks D. Xebec OP17-118 is one of the major new character cards revealed for the expansion.

For collectors who have been waiting for the Rocks era to receive major representation in the ONE PIECE Card Game, OP-17 is an especially important release.

The Four Emperors Assemble

OP-17 also celebrates some of the greatest pirates ever to hold the title of Four Emperor.

Featured legendary Emperors include:

• Edward Newgate – Whitebeard
• Shanks
• Kaido
• Charlotte Linlin – Big Mom

The set connects different generations of the Four Emperors while introducing new collectible treatments for these iconic characters.

New Super Alt-Art Cards

OP-17 introduces Super Alt-Art cards, an especially luxurious form of Alternate Art.

These premium cards feature designs covering the card with artwork derived from the ONE PIECE manga, creating a distinctive appearance compared with conventional Alternate Art cards.

For collectors who prioritise premium artwork and rare card treatments, the new Super Alt-Art cards are among the major reasons to open OP-17.

4th Anniversary Alt-Art Cards

To celebrate the ONE PIECE Card Game's fourth anniversary, OP-17 also introduces special 4th Anniversary Pirate Crew Alt-Art Cards.

Anniversary treatments include cards themed around:

• Straw Hat Crew
• Rocks Pirates
• Special Characters

These anniversary designs add another collectible layer to OP-17 beyond its standard Parallel and Alternate Art lineup.

Color of the Supreme King Haki SP Cards

Another standout feature of OP-17 is the special Color of the Supreme King Haki SP card treatment.

Also known to fans as Conqueror's Haki, these premium SP cards celebrate characters capable of wielding one of the rarest and most powerful forms of Haki in the ONE PIECE universe.

The unique theme and premium presentation make these cards particularly appealing to high-end ONE PIECE collectors.
