Play From TV Animation One Piece - Maboroshi no Grand Line Boukenki! (Japan) Online

From TV Animation One Piece: Maboroshi no Grand Line Boukenki! came out for the Game Boy Color in 2001, developed by Alpha Unit and published by Bandai. It was one of many early portable games based on the anime, arriving when the series was still fairly new outside Japan. The hardware limited what it could show, but it captured the look and feel of the East Blue saga in small, colorful sprites.

You control Luffy, moving screen by screen through islands and seas, punching and stretching through groups of enemies. The main goal is to gather your crew by finding them in specific locations, which involves light exploration and simple item collection. Combat is straightforward, mostly relying on timing and positioning rather than complex inputs. The game moves at a steady pace, and while it isn’t particularly difficult, some boss fights require a few tries. It feels like a condensed, hands-on version of the early anime arcs, letting you punch pirates and sail toward the next island without much complication.
