Form talk:Riku

Incorporate all this:

Appearance
Riku stands with features similar to other characters. His hair is silver and his eyes are blue green (which turn amber when he takes the form of Ansem, Seeker of Darkness) and has a paler complexion like Kairi compared to Sora. Riku also is more muscular than Sora showing how at first it seems that he is "better at stuff" than Sora. Riku's appearance changes more with his clothes than his actual physical appearance as he only holds two major changes. In Kingdom Hearts II he shows these changes as he becomes darkness itself in the form of Ansem. This results from him having to transform to defeat and capture Roxas. Near the final battle of Kingdom Hearts II against Xemnas, Riku returns to his normal form except with longer hair and surprisingly paler eyes. He also has more defined features and is much taller. At the beginning of Kingdom Hearts 3D: Dream Drop Distance, he is shown to have cut his hair shorter, similar to his Kingdom Hearts and Kingdom Hearts: Chain of Memories appearances.

Riku has four different outfits, his first being a yellow shirt mimicking a tank top with baggy blue jeans connected to suspenders with large shoes (in keeping up with Sora and Kairi's feet appearance). This outfit is changed when Riku turns to his normal form in Kingdom Hearts II; this time he has a black zip-up tank-top and a white and yellow vest over it, his pants are a pair of baggy blue denim jeans 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.

Also in his Kingdom Hearts II attire, there appears to be a white band on his left wrist, which is most likely an injury due to the strike to that particular wrist dealt by Roxas during their fight at the Memory Skyscraper in 358/2 Days. Riku's outfit in Dark Form seems to resemble that of Vanitas's outfit, holding the Heartless emblem on the chest and is a mixture of blue and purple with a white garment around the waist. Riku's last clothing change is at the end of Kingdom Hearts Chain of Memories, the majority of Kingdom Hearts II, and all of Kingdom Hearts 358/2 Days as he wears the Black Coat worn often by other characters. When he is not in the guise of Ansem, Seeker of Darkness, he wears a blindfold to suppress his darkness.

When Riku was a child, as seen in Kingdom Hearts Birth By Sleep and flashbacks in the original Kingdom Hearts, he had shorter hair and wore an outfit vaguely similar to the one he wears in Kingdom Hearts. He wore a high-collared, sleeveless yellow shirt with a zipper that reaches to roughly the location of his sternum. He wore black shorts and white shoes with grey soles and blue stripes on either side. Riku also had light blue wristbands on each of his hands, along with a thinner, yellow band around each blue one.

Forms
While using the power of the darkness, Riku could transform 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.
 * Dark Mode

In Kingdom Hearts Re: Chain of Memories, he transforms by saying "Darkness". This form is not present in Kingdom Hearts II.

Riku's Halloween Form is a new addition to Kingdom Hearts Re:Chain of Memories, and does not appear in the original version of the game. While in Halloween Town, 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.
 * Riku (Halloween Town)

During the fight against Roxas, Sora's Nobody, Riku takes on the form of Ansem, Seeker of Darkness. He continues to be in this form until Ansem The Wise's device explodes, causing him to finally return to his true form. Consequently, he loses many of his dark powers that originated from Ansem, such as the power to create a Corridor of Darkness (but not his own powers).

 * In The Grid, Riku is converted into data, where he wears a black suit with light blue circuitry, and visor. The forms resemble the outfits worn by other characters in the world.
