Marluxia's spirit remains as a special kind of Nobody, called an Absent Silhouette, and manifests itself inside the Beast's Castle in the Beast's room after Sora convinces the Beast to take back Belle and the rose from Xaldin. If Sora chooses to investigate the Silhouette, Marluxia reappears and engages Sora in a hectic rematch, but is defeated. A data replica of Marluxia also appears in the Cavern of Remembrance.

Marluxia is slated to reappear in Kingdom Hearts III as part of the real Organization, despite his attempts of overthrowing the original. He encounters Sora, Donald and Goofy at the Kingdom of Corona and notes how it is interesting to see Sora again, though the latter does not recognize him since his memories of Castle Oblivion have been wiped clean.
