I've pondered something ever since Greed died..
Okay, so Greed was once a regular human. He died.. And supposedly Dante tried to human transmute him. As with all the others, it didn't work out so hot, and he was probably a horrid lump of organs, bones, and flesh, just like all the others. And then he entered the world as a homunculus. Eventually (130+ years later) he ran into some problems, and was betrayed by Kimbly, and killed by Ed. And as a homunculus, he died.
Now, after he died, his skull(and most likely all of his other remnants) crumbled to dust. What does this mean? Well, I'm wondering what would happen if someone attempted to raise Greed's original human form again. Would a homunculus be born once again? His skull crumbling makes me feel that he could never return to this world again, in any form. Homunculi souls are just small leftover incomplete souls from the original body supposedly. So once he died as a homunculus, does that mean whatever was left of his soul just completely disappears from any plain of life or reality?
Well-- enough rambling. I guess the question is, what would happen if someone tried human transmutation twice? Once when the human died, and then once again when the homunculus died?
