ok,guys,i know that master yen sid said that xehanort is not alone,so i think maybe you guys want to said that maybe there was org xiii`s somebodies also there,but i think there`s more,i think ansem SoD and xemnas will also join the battle,i know all of you want to say that they only live when xehanort has become heartless,but i have theory that can make two of them alive without xehanort turn into heartless:-

 

Ansem Seeker of Darkness - first of all is ansem SoD,to make ansem is alive without xehanort turn into heartless is release the darkness inside riku just the same way he did for ven to make vanitas cuz riku have half of ansem`s power cuz if riku wants to use the darkness,he gonna be ansem itself,but thanks to kingdom hearts encoder made by ansem the wise,he can use the darkness without become ansem,but only he use his powers so thats the theory of him.

 

Xemnas - as for xemnas,to make xemnas alive is using data xemnas in cavern of rememberance.we all know that we don`t know where xehanort might be,so what if that xehanort was in cavern of remembrance to put his data into data xemnas to make him stronger and also his memories of how to summon a keyblade cuz xehanort wants to make xemnas have a keyblade cuz nobodies can`t summon the keyblade without a heart so he just put some memories of how to summon the keyblade by sleeping in the pod to share and transfer the memories in data xemnas.

 

that`s all i have to say.hope this will help

 

p.s. - correct me if i`m wrong

i think too there is some way to bring ansem and xemnas back,to fight alongside xehanort.

i believe that this could be "theres more than xehanort"thing.

but i also know rumour about vanitas and facts some XIII members return

Ansem Seeker of Darkness - first of all is ansem SoD,to make ansem is alive without xehanort turn into heartless is release the darkness inside riku just the same way he did for ven to make vanitas cuz riku have half of ansem`s power cuz if riku wants to use the darkness,he gonna be ansem itself,but thanks to kingdom hearts encoder made by ansem the wise,he can use the darkness without become ansem,but only he use his powers so thats the theory of him.

Riku wouldn't need to have his darkness extracted by another keyblade weilder to bring back Ansem SoD. Apprentice Xehanort (A.K.A. Terranort) would have to become a Heartless again in order to bring back Ansem SoD. And although Ansem SoD did takeover Riku's body and became a part of his darkness and that Riku did gain some of Ansem SoD's power doesn't necessarily mean Riku's heart and darkness would have to be extracted. Ansem SoD would have to be a being of pure darkness within Riku in order for that to happen. And I also the fact that Ansem SoD is mostly related to Apprentice Xehanort more than Riku. Plus, Riku doesn't have to be Ansem just to use the power of darkness. He has shown that he can control and use the power of darkness without having Ansem SoD's help. He can use darkness more muturelly than he had used to back in KH1. So like you had said, thanks to AtW's encoder machine Riku can handle his own darkness pretty well without using Ansem SoD.

 

Xemnas - as for xemnas,to make xemnas alive is using data xemnas in cavern of rememberance.we all know that we don`t know where xehanort might be,so what if that xehanort was in cavern of remembrance to put his data into data xemnas to make him stronger and also his memories of how to summon a keyblade cuz xehanort wants to make xemnas have a keyblade cuz nobodies can`t summon the keyblade without a heart so he just put some memories of how to summon the keyblade by sleeping in the pod to share and transfer the memories in data xemnas.

Well let me just say that data Xemnas is just a data reincarnation of the real Xemnas. he is in no way connected to the real Xemnas, nor is he even cannon to the series whatsoever. Data Xemnas was just something extra to add in KH2FM+ so that people can re-fight him anytime they want. And i doubt Xehanort knows about Cavern of Rememberence since he doesn't even know anything about it. And another thing, if you're talking about Master Xehanort, than no because Master Xehanort doesn't even now about Xemnas nor does he even know about CoR. So I really don't see how he would just randomly find CoR and put memories into Data Xemnas and make him stronger. To me, it wouldn't make sense. Now as for Apprentice Xehanort, I don't have anything to say about that. But I think he would also have no clue about his Nobody counterpart as well. So, what I said about MX goes for Apprentce Xehanort as well.

i would like to say that when the encoder exploded it eleminated any trace of ansem sod (has been said in an interview) so he cant come back that way and about xemnas i just dont think it will happen

i think new characters will be added, but shall remain a mystery because the x-saga is about to end, like Mf who knows.

No. There are way to many canonical things wrong with this. Xehanort's Heartless was vanquished so he no longer has any hold over Riku. and the cavern of remembrance were just data copies and while i cant say the place doesnt exist canonically in the story, it never provided real significance to it either.

riku lost the power of darkness in kh2

Ansem SOD's darkness definitely rests within Riku. Remember what MX did to Terra with his darkness. He could probably be able to take over Riku's body because that darkness provides a way in. Probably, Ansem SOD's darkness inside Riku will be removed later.

Ansem SoD's powers of darkness. Not his own.

It's possible lets look at the facts this is my theory(keyword theory) we know that the original incarnate of xehanort removed his heart from his body to posses terra(what happened to the original body hint hint). We know that although xehanort's heartless was defeated riku could still feel his faint influence(evident by his dark form) and continued to have it all the way until ansem the wise's kingdom hearts decoder exploded and seemingly stripped riku of his dark influence (was the influence remnants of xehanort and where did that go) we know that ansem the wise had developed something that had the potential to help(possibly revive) all those he hurt. We also know that only someone really close would have the inside scoop as to what that was and their was only one person who it would been Xehanort. So what if ansem in his experiments on the heart discovered away to revive a being baised on fragments of their being (the body/soul, the heart, the mind/memories) If it was at the time when xehanort was his aprentice then he would have had acess to the information and what if this was the experiment that was preformed on the amesiac xehanort and it revived his memories in this way xehanort would have regained his memories of the keyblade and his goals and his origins( If that was true it would also explain the subtlte influeces of eraqus and terra in xemnas as their influnces would also have been awakened). If ansem and xehanort knew of the nobodies and heartless prior to the fall of ansem and the aprentices could this have been another plan to ensure xehanort's conscious would survive to see his plans through( remember in the newly formed terranort MX told terra that no matter who took controlof the boddy he still had alternate routes he could take) Just a theory but something to think about

tutti frutti. For the time being we can assume that the darkness in Riku is gone. Whether or not it was the digital encoder is really hard to say. It did seem to remove, or at least appear to, Ansem SoD from Riku. And if the darkness was removed from Riku, along with Ansem SoD, we may never really now, but I believe that it has. As for MX, excluding his many forms, I believe that he has others out there aiding him in some particular way. He doesn't seem like the type of person to just use/rely on one individual, more so since Braig was furious for losing his eye and was out for blood. That being said, part of me believes that the castle from Zero Points may be the base of operation for MX and those, other than Braig, that are helping him. If something were to have gone horribly wrong in some major way in MX's plans, those helping him would have to have some sort of safety precaution as a back up.
