Trivia

 * This is the first One Piece video game to feature the Straw Hat Pirates as they appeared after the timeskip. It is also the first game where Trafalgar Law, X. Drake, Shiki, Caribou, Coby, Hody and Vander Decken will be playable.
 * As Secret Technique, Luffy uses the original attack Busoushoku Koka: Gomu Gomu no Gigant Jet Gatling, that is a combination of Gear Second, Gear Third and Busoshoku Haki. This attack resembles the Gomu Gomu no Gigant Gatling used in Jump Ultimate Stars. Strangly, in the Fishmen Island Arc, in order to destroy the Noah Ark, Luffy uses a similar attack, but devoid of Gear Second.
 * Law and Kid use original techniques respectively called Room: Catastrophy and Genocide Repel.
 * The 15th anime opening, "We Go!" used as this game's theme song.
 * For some reason, appearance of some characters, such as Rayleigh, Jinbe, Perona, Hatchan, Camie & Pappug are not altered according to the timeskip.
 * This is the One Piece video game with the most amount of playable characters, with a roster numbering 45.
 * With Enel, Caribou, and Smoker becoming playable, every canon Logia user in the series is playable.
