Exactly, which means it was impossible for heartless to exist in the realm of light unless someone brought a few from the realm of darkness to the realm of light.
I my view, this is a very acceptable answer and is the most logical one.
People should have realized pure blood heartless must have always existed in the realm of darkness because they are literaly darkness made real.
okay. but here is what you're missing. WHY cant heartless go through the realm of light? explain. heartless clearly are in the realm of light after xehanort accidentally made the shadow heartless; who are PUREBLOOD. now heres the thing. if they are in the door to darkness inside the realm of darkness whats your reasoning of why they cant get out?
see the point is here is heartless CAN leave the realm of darkness. why?
in the scene at the end of the world. remember that machine we saw?
it was talking about the door to darkness and how anyone being is behind that door cant pass through the door. but only darkness can...that would include the heartless so if they were in the realm of darkness the whole time why the hell couldnt they go into the realm of light like they did when xehanort made them? makes no sense.
heartless can pass through the door to darkness. human beings can't. thats why mickey and riku had to stay back. and seeing how heartless can use the corridors of darkness why cnt they transfer through the realm of light?
why did nomura say heartless werent going to appear in the game then? why did he say they didnt exist yet?
why didn't nomura give us ANY info on the heartless in bbs if they were going to appear in the game anyway?
why aren't they attacking ppls hearts?
and what heartless normally do
u cnt explain that. its a plot hole. nomura is a moron.
