's awesome hetalia creepypasta theory.
The theory is that the characters were once humans that lived in their respected countries and were reborn or sent to the world of hetalia as a purgatory, taking on the identities of their countries.
I do not believe the theory but I find this very interesting.
I'll tell you how I believe the character's that the author missed had died.
