Finland has short blond hair and violet eyes. He is the shortest out of the five Nordics. He is also often shown in the role of Santa Claus, due to the fact that Santa is claimed to live in Finnish Lapland.
Finland is described as being simplistic, gentle, and honest, as well seeming rather adult-like. He's very talkative, especially around Sweden, thinking up jokes to lighten the atmosphere. He loves to think of interesting and unusual festivals that no other country could imagine, and actually likes the taste of salmiakki. He also happens to love saunas, and the Moomins (in canon and fanon).
Before gaining his independence, Finland used to be an underling. Out of the five Nordic nations, it is said that he suffered the most hardships in his life.
