Hello everybody! We have tons of new awards for the new year that can be requested through our Awards System thanks to Antifa Lockhart! Some are limited-time awards so go claim them before they are gone forever...
According to legend, "If two people share one, their destinies become intertwined. They'll remain a part of each other's lives no matter what."
I think they share the paopu fruit together before Ven was "erased" so his legacy can still continue through Sora. Which is why they are connected...
A nobody doesn't exist because they don't have a heart. Erase means remove completely. It's simple. Aqua extracts Ven's heart so therefore he won't exist again.
It can't be Ansem the Wise. Ansem never thought travelling to other worlds was possible until he discovered the Gummi Ship which took place after BBS. Who else walks like that? It looks like Master Xehanort to me.
Ven asked Aqua to be erased, so Aqua unlocked his heart with her keyblade and it was placed into Sora. Much like how Sora sacrificed himself for Kairi. When a heart was unleashed from Sora to save Kairi's, it was actually Ven's heart.
