The ULTIMATE Theory - Everything comes together...It's all explained

First, let's go over what we know from the trailer. This is what finally made everything come together.
1.) Ven's heart is getting weaker
2.) Terra asks Xehanort ''What did you do to his heart?''
3.) Ven asks to be erased
4.) Terra is seen on Destiny Islands eyeing Kid Sora and Kid Riku.
5.) In KH2FM+, remember the Dark Portal? Portals don't open themselves

Now, here's the theory. EVERYTHING Is explained here.
Let me put it in timeline form

*Xehanort approaches Ven, knowing his heart is getting weaker. Ven wants to be erased.

*Xehanort offers to put Ven's heart in someone else to keep him alive

*Terra goes to Destiny Islands and eyes Kid Riku and Sora. At this time, Terra is about 17 years old, and Kid Riku/Sora are probably 7. Terra notices Riku is the stronger one, with more power and strength, and perhaps some other aspects which will be made more clear in BBS

*Terra chooses ''Riku''. Xehanort, however, has his own idea. He put's Ven's heart inside of SORA Instead. Terra is unaware, and fully believes Riku recieved the heart

*Ven's heart is now inside of Sora. Since this happens, everything comes together

*Sora recieved the keyblade POSSIBLY because of Ven's heart.

*When Sora became a heartless, he had 3 hearts inside of him. Ven's heart, which became Roxas. Kairi's heart, which became Namine. And a third heart... Does that mean a third nobody? I'll discuss this later

*Cut to KH2FM+, Sora enters the dark portal. At this time, Terra is expecting Riku. He instead sees Sora.

*We do not know if Terra is the one who opened the dark portal. But if he isn't...someone did. We know that.

*Now that Sora enters, Terra is confused. ''Why isn't it you that I have chosen? XEHANORT!" . Terra is clearly pissed off at Xehanort for choosing the wrong guy. In this, he attacks Sora in rage, possibly thinking him unfit

==
*This explains the title ''Birth by Sleep'' perfectly. Roxas was born from Ven's heart sleeping in Sora.

===Part 2: The future of Kingdom Hearts

*Was Ven's heart fused with Sora's? If it isn't, that means there were clearly THREE Hearts when Sora became a heartless. Meaning a third nobody...

*We know there's a ''Room of Awakening''. If Sora/Roxas went in The room of Awakening...then Ven would Awaken...instantly...meaning Roxas would remember everything...and perhaps seek Terra out

*Terra is still alive, and, by now, probably in his upper 20s. Terra meeting Roxas will be...wierd... The room of Awakening will definitely be involved

*Aqua? She's probably dead.

*Terra lives on to see KH3, Ven is still sleeping in Roxas/Sora, waiting to awaken.

*Mickey's note as seen in KH2's ending. Well, we know by now that Mickey knows, or, maybe, ''knew'' about Ven at one point, or perhaps still does. What does his note say? Is Mickey going to look for Terra, Ven, and the room of awakening as well? Does Mickey know about Roxas?

The stage for Kingdom Hearts 3 is set.

 

Yes, It did.

The battle with ''Xemnas'' really happened in Kingdom Hearts 1 Final Mix, as said in kh2's trailer ''I've been to see him''

 

I see.

Even if the battle is irrelevant, the theory still holds it's grounds almost perfectly.

 

By the way, Nomura NEVER SAID The Fight wasn't canon. That ''issue'' was never addressed at all.

Trust me. Look all you want, you won't find anything that proves me wrong.

So this theory still stands.

 

okkkay.....?
