The seventh member of the Organization. He wields a claymore, and controls the element of Moon and the Berseker Nobodies.
After Sora defeats the Heartless army at the Hollow Bastion, he appears and summons more heartless, so that he can collect
the hearts. When Kingdom Hearts is near completion, Xemnas tells Saix that he can kill Sora and his friends. In the battle,
Saix's calm and cool exterior vanishes, and he goes into a berserk mode when the moonlight touches him. However, Sora mortally
wounds him, and Saix dies while asking Kingdom Hearts to give him his heart back.
