Goofy appears alongside Donald and Sora in all of the Kingdom Hearts games. Goofy is Captain of the Royal Knights of King Mickey's court. He and Disney Castle's court magician Donald went out to search for the King, and ends up teaming with Sora for the rest of their journey.

Despite his position at Disney Castle, Goofy dislikes using weapons (instead using a simple shield in combat) and attempts to avoid fighting whenever possible, preferring to find peaceful solutions to problems. Though simple-minded and clumsy as always, and constantly the butt of comic relief, Goofy is the constant voice of optimism and, surprisingly, selectively perceptive, often noticing things others miss and keeping his cool when Sora and Donald los it. He comes off as the sage of the group, despite how he is portrayed in the Disney cartoons. His key phrase is "All for one and one for all!" —Goofy
