You can't give Riku a keyblade, he just gets it in Kingdom Hearts 1 when he goes in the Door To Darkness.
AA:
Riku is just a world specific ally so you cant change his weapon
I don't think you can
Riku's sword, Soul Eater, and his keyblade, Way to the Dawn, are not obtainable in Kingdom Hearts Re:Coded.
No, you do not. i think you can in KH2FM but im not sure.
Riku uses various weapons throughout the Kingdom Hearts storyline. He is seen with the Soul Eater and the Keyblade of People's Hearts in the first Kingdom Hearts. In Kingdom Hearts II, he uses the Oblivion Keyblade and a Keyblade known as The Way to Dawn.If you're asking what element Riku fights with, then the answer is darkness. Riku naturally had a hint of darkness in his heart, but it was further awakened due to the influence of Maleficent and Ansem's Heartless during the events of the first Kingdom Hearts. In the video game, Kingdom Hearts: Chain of Memories, Riku's main attacks consist of dominantly dark-based moves, such as Dark Aura and Dark Firaga.
You can not phisically use Riku's "Way to the Dawn", but in the final battle with Xemnas Riku lends Sora his keyblade to finish Xemnas off.
Riku is seen with the Dark Keyblade when Sora talks to him in Hollow Bastion in the original Kingdom Hearts game. However, Riku changes it when Sora fights him.
Riku wields many keyblades throughout the Kingdom Hearts series.They are as follows:-Soul Eater (used mainly in KH: CoM)-Keyblade of People's Hearts (used towards the end of Kingdom Hearts)-Oblivion (used in numerous fight scenes, mostly against Roxas)-The Way to the Dawn (used by Riku in The World That Never Was in KH II)
Riku's sword is actually a Keyblade known as Soul Eater.In Kingdom Hearts II, Riku wields another sword-like Keyblade called The Way to Dawn.
Yes. Kairi receives a keyblade from Riku towards the end of Kingdom Hearts II. It is very 'girly' and was never given an official name.
Riku is in Kingdom Hearts because he is one of Sora's friends on Destiny Island, and an important character in the series.*Slight Spoiler*As we later find out, Riku's destiny was written when he was chosen as a Keyblade-wielder, during the events of Kingdom Hearts Birth by Sleep.
In Kingdom Hearts 2 Riku gives Kairi a keyblade and she uses it to help Sora with Riku fighting Heartless in The World That Never Was.
In The World That Never Was, after you defeat Xigbar and meet up with Riku
