Form:Riku

This is a list of Riku's forms in the Kingdom Hearts series.

Kingdom Hearts Birth by Sleep version
When Riku was a child, as seen in Kingdom Hearts Birth By Sleep and flashbacks in the original Kingdom Hearts, his hair is shorter and he wears a high-collared, sleeveless yellow shirt with a zipper that reaches halfway down to his chest. He wears black shorts and white shoes with grey soles and blue stripes on both sides. Riku also has light blue wristbands on each of his wrists, along with a thinner, yellow band around each blue one.

Kingdom Hearts version
In Kingdom Hearts, Riku's hair is slightly longer than as a child. He wears a yellow and black tank top shirt with black straps crossing his chest, a pair of black gloves with matching wristbands, dark blue pants with brighter blue baggy pant legs connected with suspenders, and large blue and white shoes with black straps.

Kingdom Hearts II version
In Kingdom Hearts II, when Riku returns to his normal form, he has a black zip-up tank-top and a white and yellow vest over it, has a white thick band on his left wrist, his pants baggy and blue, held up by a black belt covered with square spike studs, and his feet down to a more normal size with a simple pair of sneakers. His hair is much longer. Riku reprises in this outfit in Dream Drop Distance, however donning shorter hair.

Kingdom Hearts 3D: Dream Drop Distance version
In Kingdom Hearts 3D: Dream Drop Distance, Riku's appearance in the Sleeping Worlds is younger wearing mainly white attire. His hair his about the same length as it was as a child. He wears a white zip-up vest with yellow lining on the sides and a black high collar. The vest also has a black sigil for the Spirit Dream Eaters on the back, indicating Riku himself becoming a Dream Eater in Sora's Dream. He also wears a pair of black wristbands, off white-blue less baggy pants with a black belt, and large white boots with a yellow lining on the bottom just above the black soles.

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's outfit remains otherwise the same as normal. These changes also apply to his Soul Eater and Dark Mode as well.

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

TRON: Legacy 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.''
