In the first game when sora comes back to traverse town riku kills a heartless in front of sora,donald, and goofy but he leaves after Sora offers him to join them. Sora then see's Riku in different worlds for brief moments after a little bit of talking. Finally at Hollow Bastion they fight for real. Riku takes his keyblade but after proving his heart is stronger he gets it back. Later when he finds him he is being controlled by Ansem(Xenhort Heartless) and defeats him. When Sora and the others finally kill ansem riku and king mickey are behind the door to darkness or kingdom hearts and in order to stop they have to seal it.
In chain of memories at castle oblivion riku and sora are both there but sora is on the upper floor while riku is at the bottom. At points Sora fight a fake riku think he is the real one but is told later he's fake. Riku however fights him to because when the fake knows he's fake he want the real one to die so he won't be a shadow. When riku finds sora he's already asleep to get his true memories back.
In Kingdom Hearts 2 Riku know looking like ansem (shown in 358/2 Days) he distances himself because he turned into ansem and is ashame. But when kairi shows sora that it's still riku they join forces. When ansem the wise's machine explodes he is normal. At the end they all go home.
Yes, they do find Riku at The World That Never Was.
My opinion Riku is Jealous because he is Darkness and Sora is Light
Did you meant Riku? Riku is Sora's best friend. He wanted to make sure Riku and Kairi are safe.
sora gets to riku by finding him Your question dosent make sense because there is no riku island
Its obvius she love sora
Because it was his understanding that Sora and Riku were the only wielders of the Keyblade.
Riku, hands down
Sora.
To play as Riku in Chain of Memories you have to defeat Marluxia as Sora
No. Riku and Sora both love Kairi.
Riku is from Destiny Islands. That is also where Sora and Kairi are from.
Unfortuantely, no. But you can use it while playing as Riku while trying to save Sora from Xemnas's clutches in the last battle of the game. At the end of the game after Sora and Riku deflect the fire beams, Riku will be attacked and Xemnas will try to kill Sora, but Riku pushes Sora out of the way and gets hit instead and as he's flying he calls for Sora to grab his keyblade, and Sora will jump and grab Riku's keyblade and use it to perform one of Sora's best finishing moves, Omnislash.
