Editing Riku-Ansem

Riku, still in the form of Ansem, helps DiZ with the process of merging Roxas with Sora. He occasionally appears before Roxas in [[The Other Twilight Town]], and, on separate occasions, steals the [[Munny Pouch]] and [[Crystal Orb]]. He interrupts [[Naminé]]'s conversation with Roxas, and holds off the Nobodies on the sixth day when Roxas enters the [[Old Mansion]]. After Sora awakens, he gives Mickey the items he took from Roxas to give to his best friend, and pleads with him not to reveal his whereabouts nor his condition to Sora. When Riku is asked by [[Axel]] about DiZ's orders to destroy him and Naminé during their meeting on Sunset Hill, he allows them to leave, much to their shock. He then gave them a word of thanks for their help during his and Sora's first encounter with the Organization in [[Castle Oblivion]] a year earlier. The two depart via a [[Corridor of Darkness]] opened by Axel.

At the end of the [[Battle of the 1000 Heartless]], Sora, [[Donald]], and [[Goofy]] are sent into a Corridor of Darkness by [[Maleficent]]. While they are there, Riku briefly appears, leaving a box containing [[sea-salt ice cream]] and a photo from The Other Twilight Town, depicting [[Hayner]], [[Pence]], [[Olette]], and Roxas.

While in Riku-Ansem form, Riku gains complete control over the dark powers of Ansem, Seeker of Darkness. He can levitate, summon the [[Dark Figure]], teleport, and expel bursts of dark energy— though these abilities are only shown when he actually transforms. He also gains his [[Dark Firaga]] ability from his [[Dark Mode]], and a [[Dark Shield]] ability (which carries over to his normal form). He can also open and use [[Corridor of Darkness]]. In this form, he is easily able to defeat Roxas and Li Shang and overpower Saïx, forcing the latter to flee.
