Within the series, two Nobodies, Roxas and Naminé, are considered "special cases" regarding the circumstances of their births. Both are created when Sora uses Xehanort's Keyblade of heart to release his and Kairi's hearts, respectively, but because of many peculiar events, manage to exist alongside their original selves, rather than in lieu of them. Unlike Organization XIII's other members, who resemble their original selves with their memories and personalities intact, Roxas resembles Ventus rather than Sora due to holding the former's heart within himself, and has none of Sora's memories due to the short duration of Sora's Heartless state. Meanwhile, Naminé is born of Kairi's heart through Sora's body and, in addition to not having Kairi's memories, has the ability to alter the memories of Sora and those close to him.
