Form:Riku

A list of Riku's forms in the Kingdom Hearts series.

Halloween Town version
While on Castle Oblivion's Halloween Town floor, Riku's skin takes on an ashen and slightly decayed look. Unlike Sora, Donald, and Goofy's drastic costume changes, Riku looks pretty much the same as he usually does. These changes also apply to his Soul Eater and Dark Mode as well.

This version is exclusive to Kingdom Hearts Re:Chain of Memories.

The Grid version
In The Grid, Riku wears a dark blue suit with light blue circuitry that bears a resemblance to his outfit from Kingdom Hearts, and a visor characteristic of participants in the Grid's Disk Wars competition. The Spirit emblem on his back is incorporated into the space of his Identity Disk.

Dark Mode
While using the power of the darkness, Riku was capable of transforming into a dark version of himself and use his dark power against his opponents. In this form, his torso, arms, and legs are covered in black and purple material that resembles muscle tissue. On his chest is a symbol very similar to that of the Heartless, and he has a white cloth around his waist.

Kingdom Hearts
''Riku gained immense power through the forces of darkness. But ordinary humans are no match for the darkness, and it is gradually consuming his heart.''

Riku-Ansem
Riku-Ansem is the form assumed by Riku throughout Kingdom Hearts 358/2 Days and Kingdom Hearts II. He appears identical to Ansem, Seeker of Darkness, wearing a Black Coat.

After the Kingdom Hearts Encoder exploded while attempting to turn Kingdom Hearts into data, Riku was purged of Ansem's influence and he transformed back into his normal form, losing his dark powers.

Kingdom Hearts II
Mysterious wielder of the darkness.
 * Ansem

What could his true purpose be?

The form Sora's longtime friend Riku chose.
 * Riku

''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.''
