One Piece (Game Boy Advance)

One Piece for the Game Boy Advance is an action game released exclusively for the American handheld market. It loosely adapts the entire East Blue Saga, chronicling the adventures of the first five Straw Hat Pirates and their ultimate voyage toward the Grand Line. It was developed by Dimps Corporation, published by Bandai, and released in the United States in September 2005.

As it was made in conjunction with the 4Kids anime, the game uses many of the same naming conventions.

Gameplay
The game is a standard side-scrolling beat-'em-up with platforming elements, featuring Luffy as the sole playable character against a variety of enemies. Luffy begins with several of his trademark techniques, both short- and long-range; as the game progresses, more can be unlocked to supplement his fighting and exploration skills.

In addition to a standard health bar, Luffy carries a three-tier "Special" bar to fuel his more powerful techniques. This bar is recharged whenever he successfully hits an enemy, with bosses providing the highest charges.

Other members of his crew like Zoro, Usopp, Nami and Sanji are also playable in the form of brief summons, to either help clear out enemies or support Luffy in some other way (For example, Sanji can cook Luffy a meal that will restore him to full health).

Trivia

 * The game's box art is a modified version of that for One Piece: Grand Battle (the English version of One Piece: Grand Battle! Rush!).
 * Much of the game's content is reused from the prior Grand Battle! Swan Colosseum (also developed by Dimps); the music is remixed straight from said game, and many of the characters sprites and animations are reused from there as well.
 * Also tying into Dimps, the gameplay of the game follows a very similar formula to the other Shonen Jump game Dragon Ball: Advanced Adventure (also for the GBA).
