America (アメリカ, Amerika?) America is an energetic and headstrong character. In the series, he is raised by England and later fights for his independence. America is very similar in appearance to Canada, who is often forgotten and was seen "invisible" by other nations. The self-proclaimed leader of the Allied Forces, his catchphrase is "I'm the hero!" His ideas for solving international problems are often absurd, but he is usually oblivious to the opinions of others. America's ideas and inventions are grand, but rarely go anywhere. His crippling fear of ghosts is at odds with his friendly acquaintance with a grey alien named Tony, who lives in his house. America is frequently seen clutching a hamburger, or eating while speaking. He is often portrayed as a rude fellow and one who has disregard for whom his actions affect or just what they might be. He has a mixed colored blond and brown hair, has blue eyes, and wears glasses. In the anime series, he is voiced by Katsuyuki Konishi in Japanese and Eric Vale in English, both of whom also voice Canada.[6] As a child, America is voiced by Ai Iwamura in Japanese and Luci Christian in English.

Italy (イタリア, Itaria?) Italy, the primary protagonist and the title character, is a bright, energetic and sweet young man. In the series, he is depicted at various points as the infant grandson of the Roman Empire (known as Grandpa Rome), and is recognized as the weakest character in the series, and as a carefree and cowardly soldier who often depends on Germany to resolve issues. He has good contacts with Poland. His artistry and extreme love of pasta and pizza are references to Italian culture. He uses his adorable ways and cute face to charm any girl he meets. He is portrayed as a "lovable loser".[5] Italy represents the northern half of the country of Italy, while his older brother represents the southern half. Hence, their full character names are Italy Veneziano and Italy Romano. In the anime series, both Italies are voiced by Daisuke Namikawa in Japanese. In English, Veneziano is voiced by Todd Haberkorn[6] and Romano is voiced by Ian Sinclair. Young Italy, known as Chibitalia is voiced by Aki Kanada in Japanese and Brina Palencia in English.

Germany (ドイツ, Doitsu?) Germany is a hard-working, efficient, bureaucratic, and serious character. In the series, Germany is primus inter pares among the Axis Powers, and takes responsibility for the training of Italy and Japan. Another aspect of his character is his relative inexperience with relationships, leading him to be very by-the-book as a result of the belief that things will go wrong if he does not follow instructions to the letter. His extreme devotion to the military lifestyle would make him an effective leader, if not for the fact of constantly baby-sitting Italy. Despite this, as the series progresses, he forms a close relationship with Italy. He notes at one point that he has a "crazy boss", a reference to the historical figure of Hitler. In the anime series, he is voiced by Hiroki Yasumoto in Japanese and Patrick Seitz in English.[6]

Japan (日本, Nihon?) Japan is a reclusive and hard-working character. He seems to have a problem with others being in his personal space, for he gets uncomfortable if anyone touches him or gets too close. In the series, he is shown to be inexperienced with the Western world, and prone to culture shock. A young man, his character design features dark brown eyes and black hair, common physical traits among Japanese people. He often tries to adopt the cultures of other countries he meets such as France. Generally quiet, he is often depicted with the attitude of a businesslike old man. As everyone else in the series, he also got another name, instead of his Country-name. In the anime series, he is voiced by Hiroki Takahashi in Japanese and Christopher Bevins in English.[6]

England (イギリス, Igirisu?) England, also known as the United Kingdom or Britain, is depicted as an irritable young man. A former pirate, he is now a cynical and sharp-tongued gentleman. Some of his notable character traits include his terrible cooking skills, foul mouth, ability to see supernatural creatures ("imaginary friends"), and ability to perform magic curses on his enemies. Britain is most antagonistic towards France, with whom he shares a long rivalry, and America, his former charge. He's usually recognized for his large eyebrows, spiky blond hair and green eyes. In the English release of the anime, when asked why they opted to choose the name "Britain" over "England", Funimation explained that it was a request from the Japanese studio.[7] Tokyopop, the English publisher of the manga, refers to him as "England." In one strip he notes that he has an older brother named Scotland.[8] Himaruya has confirmed that England represents the UK and England, while Scotland, Northern Ireland, and Wales are his siblings.[9] England's other relation is Sealand, whom England considers to be an annoyance due to his continued attempts to get other countries to recognise him as his own state. In the anime series, England's voice actor is Noriaki Sugiyama, and his English voice actor is Scott Freeman.[6]

France (フランス, Furansu?) France is a romantic, carefree character. In the series, he is shown to have a long-held rivalry with Britain. However, he frequently makes sexual passes at many characters, including England. France explains away his long history of military defeats by attributing them to a joke from God. He regards himself as the eldest brother among the European nations and is referred to as such by some of them, though he calls Spain his elder brother in turn. However, he gets very upset when another nation refers to him as an 'old man', as he claims he's still young. When he is happy, his laugh (hohonhohon) is intended to be a stereotype of him being French. He is often depicted wearing flashy blue and red clothes with a rose, holding it in his hand. In the anime series, he is voiced by Masaya Onosaka in Japanese and J. Michael Tatum in English.[6]

Russia (ロシア, Roshia?) Russia is the tallest of all the nations, but has the innocence and cruelty of a child. He adores vodka and sunflowers. His primary target of resentment is General Winter, because despite using the cold to his advantage in war, he is also attacked by him every year. Russia has a kind face, but has mentally cracked from the strain of his bloody history. Despite his brutalities towards others, he truly means well. The other nations are terrified of him, especially the Baltic Trio (Latvia, Lithuania, and Estonia), whom he loves to abuse physically and emotionally. Occasionally, he stalks China, while in a panda costume. Russia also has two sisters: his older sister, Ukraine and his younger sister, Belarus. He becomes gloomy and depressed when either of them is on his mind because Ukraine left him to try and make friends in the European Union and Belarus is obsessed with the idea of forcing him to marry her. She seems to be the only other country which Russia fears. Russia happily promises that eventually "all will become one with Russia". Another favorite phrase is "kolkolkolkol", used when he is angered. Russia is often seen carrying a water faucet pipe. For unknown reasons Poland is not afraid of him (probably because Poland is the only country that won a war with him and General Winter). In the anime series, he is voiced by Yasuhiro Takato in Japanese and Jerry Jewell in English.[6]

China (中国, Chūgoku?) China is one of the oldest nations, being depicted as immortal as well as being four thousand years old, and is regarded as the eldest brother among the East Asian nations. He is disturbed and distrustful of Russia, reflecting the Sino-Soviet Split that actually occurred after the war. China's favorite food is variety, and as such has certain tastes for things and gets irritated if a food has a certain pattern of tastes. He is a big fan of Hello Kitty and tends to end his sentences with the suffix -aru, a Japanese stereotype of how Chinese people speak. However, he replaces the customary -aru with the suffix -ahen, which means opium, when speaking to England, as a reference to the Opium Wars. After China's defeat in the Opium War, he became the cook for England and France. During the fight between the Axis and Allies, China fights Germany and Japan with a Wok (round cooking pan) and ladle, which became his weapon of choice that also serves as a stereotype that China serves good food. China's boss was introduced as a green Chinese dragon with an intimidating appearance, but in reality, he is quite relaxed and modulate as well as shown to be bullied by China in a comedic way. China is often depicted with pandas. In the anime series, he is voiced by Yuki Kaida in Japanese and Clarine Harp in English.[6]

Allied Forces The Allied Powers, primary characters within the series. From left to right: Russia, England, America, China, France.The Allied Forces group consists primarily of the characters America, Britain (also known as England), France, China and Russia. These characters are often depicted as comically failing to reach consensus in their war meetings. The representations of countries also part of the historical Allies of World War II, such as Canada, make additional appearances.

Axis PowersThe Axis Powers group of characters consists primarily of Germany, Italy, and Japan, who are also the protagonists of the series. The representations of countries also part of the historical Axis powers, such as Hungary, make additional appearances.
