I'm constantly amazed at the speed with which Hetalia is spreading. I do believe we're seeing a new pop culture phenomenon developing. I started watching the series out of a sort of sense of scholarly interest: I was very interested to see what sort of anime the Japanese would start using as an aid to teach young students. After getting a few episodes into the series, I was further amazed by... well, by the Japanese'
perculiar take on WWII and the Axis. I suppose this was to be expected... after all, in Japan textbook writers are subjected to, well, censorship isn't exactly the right word, but it's a very, very strong form of editorialism, by a
government council to only portray the war in a certain light. For example, the
Nanjing Massacre is practically never mentioned, as is the plight of the
Comfort Women.
It's so bad, there are some (even
many, depending on which demographic you ask) Japanese who
aren't even aware that the US and Japan were ever at war. (And those that do know have a... different view of the war than is taught in most countries around the world. If you can find it, check out the inscription on the plaque at Yasakuni that gives the Japanese version on the buildup towards war between the US and Japan.)
But... uh, yeah. I digress.
The series is entertaining, at least. It has that peculiar mix of drama and
kawaiisa that seems guaranteed to bring in viewers of all ages.
As for the 6th World version... I would suggest that the various heads of the Megacorps would be the logical choice. Without doubt, Lofwyr is the embodiment of his Corp... after all, his fraggin' picture is on the logo! The Draco foundation... Dunkelzahn would seem the most obvious choice, but I actually think Nadja Daviar is the best fit. Damien Knight also fits his company's persona very well.
The others are a bit harder to decide on.
