Interesting info on Xehanort’s Past.
Here is what I suspect is going on(Major Spoilers):
I suspect that the reason for Emblem Heartless being present being due to the Book of Prophecies in the Black Box. Furthermore I suspect they were generated by the Black Box so that Keyblade Wielders could release the Hearts inside them causing said Hearts to be recompleted as people.
Hearts becoming Heartless isn’t the result of Hearts being corrupted by a foreign force but the result of them being turned back into what they were when the Book of Prophecies made them.
As for the missing Upperclassmen: Luxu/Xigbar ripped out their Hearts while possessing Bragi…
Now on to the fate of Xehanort and Eraqus’s classmates: Luxu killed them sending them to where Sora and Kairi are going AKA the Verum Rex World… I noticed that the guy with the hat in Verum Rex had the same Eye and Hair Color as Bragi…
I have no doubt that Xehanort killed Bragi in retaliation for his friends’ demise little realizing that the murderer ditched the body and possessed Braig. Why was Xehanort’s friends killed? So that Xehanort would get the No Name Keyblade of course!
Eraqus of course was not fit to get it since he was the cowardly type though his master Odin saw the value of putting him in charge of Scala ad Caelem since he knew his idea of running would make him focus on hiding himself and the Keyhole away from enemy eyes.
Eraqus’s cowardly nature is what caused him to shun all Darkness.
What like Eraqus and others from Scala ad Caelem did not realize was that their kind was immune to becoming like the Heartless we see since they aren’t descended from Heartless from the Book of Prophecies.
Xehanort being the Player of Kingdom Hearts Union X was also immune and instead became Ansem Seeker of Darkness. No doubt the Upperclassmen are also Humanoid Heartless wandering around at the same time as their Nobodies.
The fact that Xigbar was able to be recompleted is unsurprising due to the fact that the Host’s Heart was what became a Heartless while Luxu remained inside the Nobody.
Of course if that’s the case than is Lauriam and Elrena’s Heartless Humanoid? Probably.
Infact the fact that Darkness/Vanitas who possessed Ven’s Body shares Lauriam’s silhouette indicates that Vanitas is Lauriam’s Heartless which means that both his Birth By Sleep death and Kingdom Hearts 3 death recompleted Lauriam after each of Marluxia’s deaths.
Of course that also means someone has been offing Elrena’s Heartless twice… Considering how Larxene’s Character File shows her despising the Heart and emotions I would assume the Heartless used her own Keyblade on herself.
