Sora returns as the main protagonist of the game.Donald Duck and Goofy also return, but are less involved in the gameplay and story. Like the first game, Chain of Memories features numerous characters from both the Final Fantasy series and the Disney animated features canon. Being a direct sequel, many of the characters from the first Kingdom Hearts reappear in this game.

Several are members of the enigmatic Organization. Other new characters include Naminé, a young girl capable of manipulating memories, and DiZ, a mysterious man concealed by red robes and bandages. Riku is also featured as a playable character in the second story mode. After being sealed in the realm of darkness at the end of Kingdom Hearts, Riku appears in the basement of Castle Oblivion. During his story, he is aided by King Mickey and DiZ.Six members of the Organization serve as the main antagonists of the game, though only four appear in Sora’s story mode, while the rest appear in Riku’s story mode. Among the four are Marluxia, the main antagonist and lord of Castle Oblivion; Larxene, a female member assisting Marluxia; Axel, a double agent whose loyalties are hidden; and Vexen, an unwilling participant in Marluxia’s plan. Zexion and Lexaeus, allies of Vexen, appear only in Riku’s story mode. Ansem also appears in Riku’s story as an entity within Riku trying to gain control of him. Many of the Disney villains return; although they are memory-based recreations like the rest of the Disney characters, they have different motivations compared to their Kingdom Hearts counterparts.
