I have a strong suspicion that at least one of the original protagonists of the Kingdom Hearts series will be gone by the end of Kingdom Hearts III.

I believe that the person who is most likely to disappear will be Terra, because, as well as the fact that his current location has yet to be revealed, he will probably want to die to protect the Realm of Light; as an apology to everyone for being a major part of why everything that Xehanort has done has occurred.

Riku seems to be another likely candidate. He knows that it is his duty to protect the Realm of Light, and I have a feeling that he will do something major that involves his sacrifice to keep the Realm of Light safe. I suppose that it would effectively kill Sora on the inside, but it would be interesting to watch.

The protagonist who I believe to be the least likely of the first three to die by the end of Kingdom Hearts III is Lea. I imagine that he would die doing something to protect Roxas and Xion (who are definitely going to return), or maybe even trying to rid Saix of his status as one of Xehanort's vessels.

Ansem the Wise seems to be another protagonist who is likely to disappear. As for the others on the list, I do not have much of a reason to suspect that any of them could potentially disappear.

Sora is definitely not going to die, because the creator has stated that the series is about Sora, and that when Sora's story ends, the series will end as well. Because it has been decided that Kingdom Hearts III is not the last entry in the Kingdom Hearts series, he will definitely not be gone for good at any point in Kingdom Hearts III. I think that a "false death" would be nice, though...

Please note that I am well aware that permanent death is seemingly impossible in the Kingdom Hearts series, with the fact that memories are immortal being a part of this.

I think Ansem the Wise is pretty much already gone. I don't see much purpose he could still have in the series unless he shows up and lead the people of the organization like he did before the became nobodies

He is not gone. He is simply trapped in the Realm of Darkness with Aqua, and he has some level of amnesia. He will come back, though I agree that it is hard to know what his purpose will be when he does.

Kairi. Sounds like something they would do to create an emotional scene near the end.

I dont think this will happen. It wouldnt really make sense for her to die since shes finally gona get some screentime and all.

Nah, the Kingdom Hearts series isn't about breaking hearts, really, so I doubt they'd do something as tragic as to kill Kairi off for good.  Riku, maybe, Terra, sure, but not Kairi.  Out of the possible options, I believe either Vanitas or Roxas will permanently disappear.  I slightly suspect Roxas will merge with Ventus in the end, leaving Sora's heart permanently and living on inside Ventus.  This is just a personal guess, though.  I really have no idea what will happen in KH3.

About the poll I thought Roxas was pretty much already gone. I'm not sure, I want to say Riku but I know that probably wouldn't happen. I'm gonna say either Terra or Lea.

I think Terra will be gone for good and Xion won't actually come back(Hopefully)

Ok, maybe you're right. That merging thing is actually a pretty good idea.
