Smithee

Who said it automatically had to be the present version?

Can't argue with the first sentence, but as for the second, that's actually my point: control over the past version via time travel.

An alternative theory (and the one I believe most) is simply Terranort from BBS via time travel.

Ultimania.

All Nomura's said about it is this: "In this game, Master Xehanort does not appear in the form of Terra-Xehanort when he transferred his heart, but as the old man he was before he took control of Terra's body. During the revival, what happened to Terra's body, and Terra's heart that was in opposition to Xehanort's control? In Kingdom Hearts, Birth by Sleep, it is to be considered that it was thought the whereabouts of the heart of Terra's master, Eraqus rested within his body."

I doubt it's so cut-and-dry. Nomura (in an Ultimania interview): "In this game, Master Xehanort does not appear in the form of Terra-Xehanort when he transferred his heart, but as the old man he was before he took control of Terra's body. During the revival, what happened to Terra's body, and Terra's heart that was in opposition to Xehanort's control? In Kingdom Hearts, Birth by Sleep, it is to be considered that it was thought the whereabouts of the heart of Terra's master, Eraqus rested within his body."

No, I said Eraqus's Heart would be.

Was hoping DDD would hint at it. Instead, time travel and MOAR RETCONS LOL.

She's a witch; why are you surprised?

I know; I meant to say it (Eraqus) would be underwhelming if it didn't pay off (ultimately failed to help Terra, despite that Blank Points buildup).

I personally think it's just the BBS version via time travel.

However, him still being Terranort would also be very underwhelming, as he's also "possessed" by Eraqus (and therefore his Light). Pointless MacGuffin would be pointless.

Robert Englund? MX: "Welcome to MY Darkness, B***H!"

Xemnas is already gone---he only appears in DDD and beyond by being time-travelled from some point before his death.

In reality, give it another year or two.

"So, which one of us is Mary Kane, and which one of us is Ashley?"

I personally nominate Robert Englund, a.k.a. Freddy Krueger.

Dear Nomura, When your upcoming climax is being delayed for several years, the most pragmatic thing to do is ease your fans over until then, not incense them more than ever and risk too much fandom burnout for said climax to sell well.

The Light Seeker Saga, where a pro-Light, anti-Darkness uprising is finally happening in retaliation for MX's constant meddling. MX (presumably trapped in his own "torment" for eternity after KH3): "...Is it my fault... My fault that the Balance has become this way...?"

^This, combined with Nomura repeatedly mentioning Terra-related hints and Eraqus's significance.

MX needs to get out of the firetrucking spotlight.

At least he was more pragmatic in the past, which was how he was ultimately able to defeat WCW--that, and the Fingerpoke Of Doom.

There's also Vince's constant arrogance.
