He is the human personafication of country Iceland

Appearance: Iceland has silver-white hair, described as being somewhat tousled or "bed-headed". He wears a deep brown military jacket, a white dress shirt with a ribbon tie underneath, deep brown straight-legged pants, and white half-laced boots. He also sports a pair of white gloves. He's usually seen with a Puffin-like bird, which sometimes sports a pink bowtie. Himaruya revealed in Volume 3 that his puffin's name is "Mr. Puffin" and what differentiates him from normal puffins is his black belly and pink bowtie. Mr. Puffin looks cute, but speaks and acts like an Italian Mobster. He is the youngest of the Nordic countries, 16 years old

Personality and Interests: He appears relatively cool and composed on the surface but is warmer and passionate ("hot-blooded") deep down. However, he doesn't show it because he's embarrassed and afraid of getting teased by it. It's the same for his accent. Iceland tries to hide his distinguishable accent and prefers to speak in English if he can. Rather than be called weird, he's widely known as aesthetic and very different compared to other European countries. Iceland appears calm, cool and doesn't talk much. He appears to be matured but is actually trying to hide his childish sides. He is a bit uninformed of the latest news since his house is separated from other countries but keeps up with American websites. Due to his recent financial problems, Russia has been helping him. Though he is treated kindly by him, he can't help but feel suspicious. When Hungary implements that he's one of the younger ones and can't be exposed to a sensitive ghost story, he simply denies that he's not one of them. He's short-tempered when it comes to Mr. Puffin. Iceland is mildly angry when the other Nordics pester him to call them (Norway especially) big brother because he's confirmed to be an adult and wants the others to stop treating him like a child, he wants to feel like a part of the crowd (he already is). He could see fairies and magical beings, as proven when Norway tries to persuade him using fairies called The Bøyg but prefers to pretend he can't. As a child, he was introverted and lonely. He sent out letters hoping people would be interested in him but to no avail. As he got older and things began to improve, people began taking an interest to him but with Denmark and England quarrelling and almost being captured by African pirates, he wanted them to leave and felt that being lonely was better.

Relationships with other countries: Denmark: Denmark tries to force Iceland to call him big brother by saying "All drinks are on Ice until he says it!". Denmark likes calling Iceland "Ice" or "Icey", and sees him as a younger sibling, like Norway. France: France compliments of Iceland's phrasing being unique and interesting, continuing to offer Iceland to get together with him for some poetry sometime. Iceland instantly freezes and puts on a face that screams NO. Japan: Iceland sometimes chats about seafood or computer related topics with Japan but does not appear to spend much time with him apart from this. They can typically be called long-time casual acquaintances. Norway: It is said that Iceland considers Norway to be the home where his heart truly is, while Norway in return feels that Iceland is very important to him and sees him as a younger brother. It has been revealed that Norway and Iceland are indeed brothers, after Iceland opted to get a DNA test (in actuality an excavation) done. When Iceland found this out, however, he seemed embarrassed or upset because he didn't want to refer to Norway as "Big Brother" (onii-chan). Iceland sees Norway as an older brother, even though he doesn't want to admit it. Iceland and Norway have a very close friendship, even going to the length of referring to each other as punks. Norway enjoys teasing Iceland, but there’s a clear emotional investment, and he looks after his little brother’s well-being. Norway does pry into Iceland's business, but secretly Iceland doesn’t mind Norway’s interference.

Other facts: His birthday corresponds with the date that Iceland was officially declared a republic, on June 17, 1944. In The Unknown Secret Story Of Iceland's Birth..., Iceland remembers the very first time he opened his eyes after being born and potentially hearing his big brother's voice but not able to find him. According to himself, the first worlds he ever spoke in an eerily chilled voice were to search for a place to rest, some food to eat, and warm clothes to wear..
