WMG regarding the official non-nation characters goes here.
Tony is the representation of Italian immigrants.In history, because of the TO: NY stamps on their passports, those checking their passports would mistake that for their name, calling them "Tony". This explains why he lives in America's home.
Tony is the Nation-tan of an alien planet.No need to explain this one.
Tony is Puerto Rico.After all, it's in a weird limbo, a part of the US that feels like an independent country. And this would explain why he lives in America's house.
America is illegally subletting parts of his home to Tony.Which means he's an illegal alien.
Kumajiro does know who Canada is; he just likes to mess with him.Proof. "I asked who about someone other than Canada?"
Germany's unseen boss is Adolf HitlerIt's pretty obvious
Alternatively, Germany's unseen boss is Adenoid Hynkel.With Hetalia having elements of Politically Correct History, this would be an interesting twist in what we all thought was the obvious truth.
Hanatamago actually represents the Åland Islands.
Kumajiro represents the Northwest Territories.Or, alternatively, "Northern Canada" as a whole. Kumajiro is a polar bear, which is known to live in Canada's Northern territories, and the reason he's so small despite his species is due to the lack of development up north.
When the kappa said goodbye to England and left Japan's house, it went to Gensokyo.
Prussia's little bird actually represents the Prussian coat of arms.See also the guess above this one. Not only will Prussia live on, but he's got the flag-tan to prove it!
ALL the tans are actually an Alien species - Tony is their mommaIt's an alien species that's somewhere between symbiote and a parasite lays eggs on planets with the potential for sentient life, usually tucking caches of the eggs in areas particularly liking to foster civilizations judging by the locations of the most evolve species. These eggs can lay dormant for millennia. When the cohesive thoughts and emotions of a people reach the eggs, the one at the top of the grouping will enter a stage of activity, using the thoughts and emotions to create a beings that can walk among the sentient beings above as one of their own. The alien-being, however, gains sustenance and near-immortality as long as the culture that created them flourishes, even if daily sustenance can also be gained by eating edibles. (Also, due to the sentient species on their planet talking longer than expected to reach North America, only two eggs were viable - Canada and America. The Aliens realized their miscalculation in time to lay new broods in South America, though) Eventually, Humans and the "countries" will realize around when the sentient species develops Interstellar travel capabilities, and the "countries" will hit the True Puberty of their species. (Also, Tony is their mother/guardian/caretaker of the hatched on the planet.) Canada and America, due to how late they were born have some physical issues, to say the least. They went through cycles of adult forms and child forms, at least until they had the stabilizing influences of others of their species (And the Mythological Twins in North America were based on them and the legends spread like wildfire, LOL). America actually has more issues than Canada, thus why Tony sticks so close to him. The physical forms they took on at their birth don't always match their true genders - thus, Hungary growing up thinking she'd be a he is actually true.
Tony is the nation-tan of the moon.He lives at America's house because America planted a flag on the moon. Tony is an amalgamation of the moon landing, pulp sci-fi fiction, and the tradition of planting a flag on land you claim for your country. He's not human because there are no human settlements on the moon (yet).
China's dragon boss is the representation of the Communist Party.The staff could not portray the communist leaders for fear of provoking the Chinese.
Tony is actually Mexico-tan...This may sound a tad unfortunate, but Tony is an alien that lives in America's house. Also, Tony is a common name for Hispanics.
Russia's boss is trying to kill him.See this strip Why would you give the personification of your nation such a dangerous job unless you actually wanted him dead? It is insane, of course, but this is Josef Stalin, and from what I know, it somehow seems like the kind of thing he would do. Maybe Russia is seen as a sign of the past, not a symbol of the USSR, and Bloody Sunday would hardly have stood him in in good stead. But seeing as this is Russia we're talking about, you wouldn't want it to be too obvious you were trying to murder him, and so he just gives him the most dangerous jobs he can.
Alternatively, he's not actively trying to kill him, he just doesn't care if he dies, for the reasons stated above.
The fat lady who work as a teacher in the Gakuen Hetalia game is the African Union.This lady◊. All the teachers in World Academy are like this, the old man Mr. UN (from this◊ strip) is the Principal and the World Trade Organization is the school nurse.
Kumajiro is a figment of Canada's imagination.Since poor Canada is always getting ignored, he needed an imaginary friend.
United Nations is actually Earth, the teachers in Gakuen Hetalia are the continents.I think UN◊ looks awfully old to say he's younger than most of the nations. Really, he just represents Earth, but because there's not a lot to do in that role he takes the most appropriate job he can get. As for Gakuen Hetalia, there must be some significance to the nations being in continent classes. An earlier guess was that the African class teacher was the African Union, which would also fit in here; just like Earth, they take appropriate jobs.
The Lemony Narrator from the dub is a personification herself.She's a personified textbook. She also really, really hates her job.
Tony has a cousin named Paul.There's a movie coming out soon, called Paul, and the tititular alien looks awfully familiar...
Australia's Koala is f*cking evil.I know it's been said to death, but LOOK AT HIM! The damn thing is giving a Nazi salute! It even has it's left arm behind it's back and a nose similar to a toothbrush mustache, like some over-the-top dictator. The evil eyes really don't help.
Australia's Koala is The Man Behind the Man.Likely, he's the personification of the Death World / Everything Trying to Kill You aspects of Australia. Oz knows not to mess with him, so he just let's the Koala run the place. That's why Australia also appears to be giving the Nazi Salute; the Koala must be coercing him somehow. The rest of the world is just relieved that they don't have to share a landmass with him.
Australia's Koala is like Sweden.It looks terrifying but, really, it just wants to cuddle — hence why Australia is so willing to carry it around. He's knows it's secretly a marshmallow inside.
Mochimerica was the one who took the embarrassing pictures.We saw him when he took the one with Iggimochi, is obvious he's working for France or alternately...
Picardy was the one who took the embarrassing pictures.The pictures are from the April Fool's Aftermath Game and we will see them when Himaruya releases the whole game.
Tony is the nation-tan of Brazil.Because it'd be hillarious if it was real.
Australia's Koala is a Dropbear.Just a thought, considering how evil it looks as discussed by an above WMG.
A nation's pet will live as long as the nation does.Think about it. These nations have had their pets for a long time. We see Gilbird delivering a letter to Austria and Maria Theresa regarding the invasion of Silesia, and then we see him again in the present. Tony, America's alien friend, has been around since Roswell in the 1940s. My theory is that, once a nation picks its companion, a special bond is made, and that pet/friend/whatever will remain with the nation for as long as the nation lives. So, if Prussia were to suddenly disappear, Gilbird would do the same, as he has already far exceeded a bird's normal life span (if he had been a baby bird during Maria Theresa's rule, he'd be 400-something or 500-something years old today).
All the Mochis have special filling inside them.Well, they're mochis, and usually mochi has fillings inside. Them, being mochis, have filling correspondent with their respective nation's food stereotypes. And of course they can be eaten. When eaten, their body dissolves into said filling, making them one big giant food stock of all the nations around the world when they're hungry. The fillings are, for example:
"Allen" isn't merely a British messenger, but is actually the tan of a British territory.It wouldn't be the first time that a territory of a country has been seen being used as a messenger or something similar. I'm pretty sure that Russia has used Lithuania before as a messenger, and Saxony and Bavaria were (in the manga and webcomic) shown to be personal guards of the Holy Roman Empire. My guess is on a territory near America with some sort of American ties, due to his memetic similarity in appearance to America, but in theory he could be someone else without ties to America.
Death is personified, and he lives in America's house.I've got a couple things to back this. I know Death would be personified well before this, but who's to say he doesn't have more than one house around the world?
Tony actually represents New Mexico.Area 51, anyone?
Hetalia's Joan of Arc is inspired by the eponymous clone in Afterschool Charisma (or vice versa).Both resemble each other more than the Real Life historical figure.
the nations are all bisexualin any nation there are hetro and homosexual people in every country so to represent the people of their countries they are naturally both.
