Shonen Jump's One Piece (2005). Play online

Summary

When I first slipped the cartridge of Shonen Jump's One Piece into my Game Boy Advance, I was struck by how oddly American it felt. It’s the only One Piece title that never saw a Japan release, and its ties to the 4Kids dub give the visuals and dialogue a distinctly early‑2000s localization flavor. 

The game plays as a side‑scrolling beat ’em up where I control Luffy with a single‑button combo system, calling in crew mates like Zoro as summons. Roughly fifteen playable characters pop up through the stages, and twelve varied bosses—including Buggy and Chaser—challenge each level’s pacing. Treasure from the anime appears as collectable items, and the stages react with interactive background objects that make exploration feel rewarding. 

A curious tidbit is that several sprites were lifted from the Japan‑only WonderSwan title One Piece Grand Battle: Swan Colosseum. Critics gave it middle‑of‑the‑road marks, with GameRankings averaging 72 % and Metacritic landing at 76/100, but for anyone who grew up with the 4Kids era it remains a nostalgic slice of GBA history.

Storyline

In the Game Boy Advance title One Piece, you step into the shoes of Monkey D. Luffy and his Straw Hat crew as they set sail for the Grand Line. The game mirrors the spirit of the earlier One Piece: Become the Pirate King! by letting you use Luffy’s Gum‑Gum powers to punch through marines and rival pirates. The story follows the East Blue Saga, taking you through iconic locations like Orange Town, Syrup Village, and Baratie while hunting the legendary treasure known as the One Piece. Each battle is presented in a side‑scrolling action format, letting you collect items, level up, and unlock new crew members as the adventure unfolds.
