The One Piece x MLB Art Card is an unlicensed 2025 set that sits in an unusual crossover space between anime fandom and baseball card collecting. Trading cards built around a popular manga and a major sports league are not a new idea, but this set stands out for bringing together two very different collector communities. Its unofficial status is part of its story, giving it the feel of a fan-driven project that collectors remember as a distinct moment in the hobby's recent history. Card #2 features Roronoa Zoro, the swordsman of the Straw Hat crew, rendered in the set's blend of manga character design and ballpark-inspired imagery. Zoro's three-sword style and steady, understated presence make him a favorite subject for fans, and collectors often seek this card for how cleanly it captures his character. It is a natural centerpiece for anyone building a set around the crew's core members.
