what the h..couldnt anybody tell me that before i started creating this embarasing theory??Heartless and Nobodies don't exist in BBS, when Unbirths do, however. They don't come into existence until about a year later, when presumably the Unbirths aren't around.
It's still possible that they're made up of memories, just not that they're created during the process that a Hertless/Nobody is.
yeah maybe thats why they are called unbirth,cause in real life they never get a real body or heart,just memories's creation
