Sweden is a silent man, who seems to scare the hell out of a lot of people, due to the fact that he always seems to be scowling. But he's actually pretty nice...if you're not Denmark. According to his wiki, in Hetalia archives, he is very playful, deep down, though he doesn't get to show it that often, but sometimes, he can get too embarrassed, and becomes too shy to say anything. He's also implied to be very strong. He seems to have a soft spot for Finland, and often refers to him as his wife.
