Tony
America's weird alien friend—or at least, that's what America calls him. Nobody else really buys the alien thing, which frustrates Tony to no end, especially when it comes to England. England flat-out refuses to believe in aliens, which is hilarious considering he's totally fine accepting fairies, ghosts, and all sorts of other mythical creatures. The irony isn't lost on anyone.
America's basically the only person who takes Tony seriously, though even he doesn't actually think Tony's an alien. This leaves everyone else asking the obvious question: so what is he, then?
Tony's pretty into video games and clearly knows his way around tech. He's got serious skills with computers and that kind of stuff. He actually stepped up to help the main cast during the events of Ginmaku Hetalia Axis Powers Paint it, White, lending a hand in their battle against the Picts.
