KH2 KH3 Fan Fiction
Many people asked; what if Sora never got that letter from Kairi? What if Sora and Riku never left the realm of darkness? Many people asked, so I am answering their questions in my opinion. Let's begin where KH2 ends.
KH2 Ending to KH3 Beginning
So here is my theory. I assume after a while of hanging around in the realm of darkness Sora and Riku are going to be able to travel the darkness willingly. Most likely they will travel the worlds sorting out any trouble caused by the heartless and the nobodies. The Nobodies with out any leader ship will probably end up causing more damage and destruction to each other and to other worlds because they will do whatever because of their absent leaders. I don't think that Sora and Riku being in the dark realm will change their disposition at all. If this were to happen and affect KH3 in any way I don't think much would change except that you would use the darkness to travel from world to world and Sora would have a Cloak and have some awesome new moves. Sora and Riku would stay Keyblade bearers. I also don't believe that there visual appearance will change like how Riku had the appearance of "Ansem" This is my opinion on what would happen if Sora never received the letter from Kairi and never left the dark realm.
