Riku

Riku is the wielder of the soul eater finally gets his own keyblade. Riku first appeared in Kingdom Hearts. Riku was the intended owner of the keyblade, but he gave into darkness and the keyblade chose Sora. Riku later teamed up with the disney villans and was possesed by Xehanort's heartless. Riku was later freed and ultimately became Xehanort. Riku gained a keyblade called way to the dawn(it is unknown how but it is most likely after his visit to the land of dragons seeing as he had the soul eater in that battle. He also gave a keyblade to Kairi which makes Kairi a new keyblade master but it is unknown how he obtained it.) Riku is a very skilled keyblade master. The origins of the keyblade is unknown at this point but it is spectulated that it's origins will be explained in Kingdom Hearts: Birth by Sleep (being the most likely game)in the past Riku betrayed Sora in his lust for darkness, but Riku later chose the path of dawn meaning he is both light and dark. Now after defeating Xemnas with Sora, Riku and Sora have decided to end this trouble.
