Welcome to Kingdom Hearts Answers. What would you like to know?

It all depends on whether you choose to believe in me or not.

Plot details for the Kingdom Hearts series follow.

Well, I think everything after KHI was just added on, to be honest. You'll find no clue of Ventus, Roxas, or even the fact that Ansem from KHI was a heartless. - TidusTehSacrificer357 01:04, November 19, 2012 (UTC)

That's because Square Enix made KHII after Squaresoft made the original KH a success. Although, I thought it was pretty obvious that Ansem, Seeker of Darkness was a heartless, considering the heartless symbol on his chest, but my assumption could have been wrong, I guess I was right though, according to Square Enix. :D  Timelinesplitter Chaos 01:56, November 19, 2012 (UTC)
Didn't the ending of KH1 already show hooded Roxas and Riku at the memory skyscraper? And Final Mix introuced Xemnas (he was hooded and did't crearly speak though), and was still Square alone at the time.
If you play Chain of Memories it appears quite clear that they already had KH2 in mind. Thing I'm quite sure were added later are Xion and Coded. I can't say anything about BBS. I still have to play it (main reason I hate SE for not adding all the games in in the HD collection)...AkaAxl 13:46, November 19, 2012 (UTC)
My bad, actually Square Enix made Chain of Memeories and onwards, but the Final Mix and extra ending of the first game is a good point. So I suppose it's debatable, although, that's supposed to be Riku in the hood.  Timelinesplitter Chaos 15:33, November 19, 2012 (UTC)
You see both. Roxas is down with his hood up, and then you see Riku atop of the skyscraper with his hood down and a blindfold.AkaAxl 16:55, November 19, 2012 (UTC)

Oh yeah, my bad again, lol. That's a very good point, I may be stumped, but I'll get back to it.  Timelinesplitter Chaos 21:06, November 19, 2012 (UTC)
Interesting, I didn't know about that. I never did go for 100% in KH1. But I honestly don't know when they planned the plot, but from what I see here, they obviosly had Chain of Memories and KH2 planned when they made the first game. Although I don't think they had BBS or 358/2 Days planned. {{SUBST:User:DarmaniTheFourth/Sig}} 22:55, November 19, 2012 (UTC)

I'm Baaaaaack! In any case, To continue what I was saying earlier: I think they probably planned for the whole Riku side-story before-hand, as well as Roxas and the nobodies, as for Xehanort and Ansem's story, I think Square Enix had their own hand in that, I dunno, it just seems more like their story, rather than Squaresoft's... Timelinesplitter Chaos 04:31, November 20, 2012 (UTC)
