Finland is described as being simplistic, gentle, and honest[12], as well seeming rather adult-like.[1] Estonia, a friend of his, described him as worrying a lot but with a strong core.[13] He is calm[14] but serious and hard-working.[15][12] He is said to show "great physical strength" during fires and is abnormally strong against the cold.[1] He's very talkative, especially around Sweden, thinking up jokes to lighten the atmosphere, however he is actually a quiet individual.[12][14] He loves to think of interesting and unusual festivals that no other country could imagine[12][1], and actually likes the taste of salmiakki.[12] He also happens to love saunas.[1]
Before gaining his independence, Finland used to be an underling.[12] Out of the five Nordic nations, it is said that he suffered the most hardships in his life.[16] He also sometimes feels a bit like an outsider with the rest of the Nordics due to having a Finno-Ugric language rather than a language derived from Old Norse.[17]
In one of the "Extra Strips", it appears that he doesn't have a good naming sense.[18] It is said that he'll let you poke him up to ten times but he'll return it many times over if you go over that amount.[14]
