Replica bodies to form his ideal Organization XIII with Xigbar, Saix, and Vexen. Sora is narrowly saved from being Xehanort's final vessel with the aid of Lea (Axel's original self) and Riku learns about data that Ansem the Wise had implanted within Sora during his year-long sleep, which may be used to save those connected to Sora. At the end of the exam, Riku is declared a Keyblade Master; in Kingdom Hearts HD 2.8 Final Chapter Prologue, Sora embarks on another journey to regain his "Power of Waking" while Riku helps Mickey find Aqua, Yen Sid training Kairi and Lea so they can help in the final battle against Xehanort and keep him from the Princesses of Heart.

Sometime later, all the guardians, including their close friends and allies, celebrate victory at Destiny Islands.
