Think about it: the rules of body-swapping and moving your heart between vessels never deliberately said you have to stay within your designated sex

 

Xehanort could very well have started out as a woman who possessed Xehanort who possessed Terra who stole Ansem's identity who possessed Riku who became old man Xehanort again

 

But why stop there? The possibilities are endless

 

 

HDsoSexy a coincidence? Perhaps

This is clearly the plot twist we have been expecting to appear in KH3

You're forgetting the one where Kairi's Grandmother is actually Sora's sister Which means Kairi is Sora's nieceAnd we thought George Lucas had weird incest issues

If Larxene didn't get killed he would have been inside her

Your theory is clearly untrue because....

 

SHE DOESNT HAVE DEM YELLOW EYES.

So that would mean Spock was a woman the whole time too...

Obviously, I mean he planned to make Larxene one of his vessels after all, before he got wind of her betrayal,

If Larxene didn't get killed he would have been inside her

In more ways than one my friend.

like other here says, Larxene was in his list of vessels (Xion too? he wanted eliminate roxas and keep xion at the start)

usually when someone is possessed (like riku-ansem and ventus-vanitas) he's talk in a "double voice" and i think in DDD nobody is doing this because the process is not complete (braig/xigbar says he half xehanort)

so i was thinking.... in that case is not like she started speak.... with a male voice, right?

 YMX was when Riku fought him. That's why his eyes glowed . Also , it is inferred that when MX had Saix/Isa attack it was MX doing it through him. Notice after Xigbar says to do something old man , MX gives that sly smile and immediately Isa jumps to attack like a robot with a total blank look on his face and says nothing.

YMX has speaking like that? i don't remember this, i'll have to play it again sometime

MX using Isa like a puppet could be, but could even be somethink like "let's see what's you're reaction at this, lea" (the character not you )

and is not like Isa was very talkative and full of expressions on its on..... for what i know the no certainties about he can have a full control on the vessels, or i'm wrong?

Nomura's words himself answer all of this and yes MX plans to fully control all his vessels

 

When King Mickey stopped time, Young Xehanort began to move. Since he can control time, was he breaking the King’s spell?

Nomura: Young Xehanort wasn’t using his own power at that time. The King’s magic was broken because Master Xehanort was assimilating with Young Xehanort. Only “the mark of heresy” was added by Organization XIII.

— It was when the figures started appearing in the thrones.

Nomura: Indeed. Time was stopped just as Master Xehanort was materializing. So he moved his consciousness to Young Xehanort’s body. Reacting to this, King Mickey exclaimed, “That’s impossible!” Young Xehanort was holding a Keyblade that he originally wasn’t able to handle thanks to Master Xehanort’s power. Though the keychain on it is different, the Keyblade he takes out is Master Xehanort’s.

— I see. Young Xehanort himself is still in Destiny Islands and isn’t able to wield a Keyblade yet.

Nomura: Right. Even when he appeared as an additional boss in Kingdom Hearts Birth by Sleep Final Mix, he wasn’t using a Keyblade.

—By the way, Braig’s dealings with Master Xehanort in Birth by Sleep make sense, he was to become a vessel.

Nomura: There is a certain reason for Braig to proudly exclaim, “As for me, I’m already half Xehanort.” Isa (Saix) is included too. I think you’ll understand the details about their circumstances eventually.

— What happens to the hearts of those who have had Master Xehanort’s heart planted within them?

Nomura: They’ll gradually be swallowed by it. As for Master Xehanort, he plans to control them completely. The planted parts of the heart are captured rather than disappear.
