Riku-Ansem



Riku-Ansem is the form that Riku takes to capture Roxas at the request of DiZ to awaken Sora and restore his power. Roxas was overpowering Riku during their battle, but Riku was determined not to lose the Nobody, so removed his blindfold and revealed the dark power of Ansem that he had been hiding within him. He succeeds then in defeating Roxas and takes him away to where Organization XIII cannot find him.

Riku takes this form at the end of Kingdom Hearts 358/2 Days and continues to remain in this form throughout most of Kingdom Hearts II. In this form, he appears identical to Ansem, other than his clothing, and even refers to himself as a pseudo-Ansem. However, those who truly know Riku can sense Riku behind the appearance, as witnessed when Sora recognizes him in the Land of Dragons. In The World That Never Was, Naminé reveals Riku's true identity to Kairi, who then tells it to Sora, Donald, and Goofy.

After the Kingdom Hearts Encoder exploded while attempting to turn Kingdom Hearts into data, Riku was transformed back into his normal form.

''Though Xehanort tried to control Riku from within, Riku's heart proved stronger. But the only way to wield darkness fully was to become it.''

''Riku began calling himself "Ansem", perhaps as a sign of resolve. He would live in darkness if that's what it took to wake Sora.''

Kingdom Hearts 358/2 Days
Riku takes this form at the end of Kingdom Hearts 358/2 Days when he is defeat by Roxas, Riku already know that he will use this form, and Mickey made a promise to never tell Sora about what happened with Riku. In this form, he appears identical to Ansem, other than his clothing, and even refers to himself as a pseudo-Ansem. After Riku-Ansem defeat Roxas, Ansem the Wise appear and take Roxas. After this, DiZ put Roxas into a Simulated Twilight Town, to continue the progress of Sora's awaken.

Kingdom Hearts II
Riku continues to remain in this form throughout most of Kingdom Hearts II he helps DiZ to awake Sora, he also put Naminé in line when she trys to contact Roxas. When Roxas try to enter in the Old Mansion, several Nobodies appears, and Riku-Ansem defeat all the Nobodies for Roxas.

He appears again in Land of Dragons to alert them about the Storm Rider. Mulan is the first who saw Riku, and try to catch him. Sora, Donald and Goofy arrived. Sora, Donald, Goofy and Mulan go to Summit and finds Riku. Sora confronts Riku but he escapes and go to Imperial Place to talk with The Emperor. Riku-Ansem defeat Li Shang and talk about the Storm Rider. After this, he leaves the world.

Riku-Ansem appear again in The World That Never Was after Naminé help Kairi to escape. Saix appear to capture the two girls, but Riku appear with his keyblade and confronts Saix, but he escapes. Kairi discovered the true about Riku, and they go see Sora, in the Castle That Never Was several Shadows appear, and Riku summon two Keyblades, and give one to Kairi for fight. After Sora defeat Xigbar, he meeting Kairi and Riku-Ansem, Sora think that is Xehanort's Heartless, but he discovered that is Riku but take the form of Xehanort's Heartless. Sora, Kairi, Riku, Donald and Goofy go to confront Xemnas, but first, they had to defeat Saix and Luxord. In the Naught's Approach the Ansem's Kingdom Hearts Encoder exploded while attempting to turn Kingdom Hearts into data, Riku was transformed back into his normal form.

Abilities
While in Riku-Ansem form, Riku gains complete control over the dark powers of Ansem, Seeker of Darkness. He can levitate, summon the Guardian, teleport, and expel bursts of dark energy (though this is 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 Corridors of Darkness.

However, when the Kingdom Hearts Encoder exploded and he was reverted out of this form, his heart was no longer tainted with darkness, so he could no longer use many of the abilities of his Riku-Ansem mode (as revealed when they attempted to leave the World That Never Was and Riku failed to open a Corridor of Darkness).
