The Eternal Paradise
Chapter I: Replica Program
The Replica Program, created by Organization XIII in an attempt to obtain the power of the Keyblade Master. The first of the Replica Program special Nobodies was Replica Riku, an imperfect copy of the Keyblade Master's best friend. Replica Riku was created by Vexen to confuse the Keyblade Master. Replica Riku was defeated in Castle Oblivion and marked a failed project.
The next replica was Xion. She was meant to be a replica of the Keyblade Master. Xion's appearance changed based on her relationship to the viewer. Two of Organization XIII's members, Roxas and Axel, saw Xion as a female. The three of them were best friends and always ate ice cream on top of the Twilight Town clock tower. One day, Roxas abandoned Organization XIII and saw Xion on the clock tower. Unfortunately, Roxas had to kill his best friend in order to free Kingdom Hearts, a large heart-shaped moon that housed every heart unlocked with the rage of the Keyblade. Xion returned to the Keyblade Master, restoring the weakened Roxas' strength. Xion was a failed project too.
