Hetalia fans are nicknamed "Hetalians".
Because most Hetalia fans have short attention spans (including me) XD
Hetaoni is a well know video game based on the original series Ao Oni. A majority of Hetalia fans have played or have heard of the game. That does not mean that it is know by everyone however. As for the games popularity, it is a good game and many people enjoy it even through the complications and few glitches it contains. So it depends on what you consider popular. But in a sense, yes it is popular amongst Hetalia fans
The nickname for the Attack of the Titans fans are "troops."
This is a relatively subjective question, but many Hetalia fans and Ao Oni fans consider Hetaoni to be a fun game.
This is a question that seems to wonder many Hetalia fans. But China is, in fact, a man. Though, in one (dubbed) episode, he draws a portrait of himself on the chalkboard, which is extremely feminine.
Not really, but many fans believe so. There may be hints, but all of it is fan based.
His name is only mentioned once, but Canada called him "Mr. Kumakichi" instead of "Mr. Kumajirou".
