Birth by Sleep Eraqus' Nobody and Heartless -Spoilers-

My question is somewhat simple.

Because of the fact that, after he's defeated, Eraqus' heart rests in Terra's body, would that mean that Xemnas and Ansem, Seeker of Darkness, are Eraqus' Nobody and Heartless as well? We know that they're Apprentice Xehanort's Heartless and Nobody, and Apprentice Xehanort was Terra-Xehanort. The reason they were able to also be Master Xehanort's Heartless and Nobody was because his heart was in Terra's body, which was the body of Apprentice Xehanort, too. So with that in mind, is it possible that Xemnas and Ansem, Seeker of Darkness, are Eraqus' Nobody and Heartless in a sense, too?

 

It's possible however would that mean that Ventus is part Roxas (and maybe even Namine's) nobody as well?

 

They're all basically hybrids; You see how Roxas is Sora's nobody but his apperance is Ventus' but his clothing is mixed between both sora and ven. And then there is xemnas who isn't pure Xehanort because basically the body is Terra's but the mind is Xehanorts so in itself their apperance is based off Terra of course but their mind set is in xehanort. I wouldn't delve too much into the theory of them being cross hybrid nobodies of Eraqus terra and xehanort because Eraqus's heart but basing things off this theory; because Xehanort became whole himself again..this could be a reason as to why the master keeper arrived at destiny island who knows. but if it's true then maybe Eraqus will come back himself in KH3 to teach sora a thing or two.

 

To be fair, we don't actually know Eraqus' heart is in Terra. Xehanrot just says he's a sly dog. It could be some sort of enchantment or an as of yet unknown plot point
