Xion

Xion is the de facto fourteenth member of the Organization, introduced in 358/2 Days. Similar to Roxas, she wields a Keyblade and appears to lack memories of her past. While first appearing emotionless and static, she eventually befriends Roxas and Axel, and joins them on missions. Xion eventually discovers her true identity as an artificial human "replica" created from Sora's memories to duplicate Roxas' powers, which forces her to sacrifice her existence and all memories related to her in order to protect her friends. She is later revived as the final member of Xehanort's thirteen "seekers of darkness" before regaining her original memories and opposing them. Unlike the other Organization members, Xion does not have an original human name. Her name is an anagram of "No. i", the imaginary number. Xion is voiced by Risa Uchida in Japanese; in English, Xion is voiced by Alyson Stoner in 358/2 Days and Kingdom Hearts III, and by Hayden Panettiere in Birth by Sleep and Dream Drop Distance.
