As she is based on the United States, she is depicted as the strongest among the Flag Musume. Her personality is mostly portrayed as extreme 'my-pace' (doing things at her own speed), but fan interpretations exist where she becomes more ruthless than anyone else when truly enraged. She is often drawn in a pseudo-mother-daughter relationship with the UK, and fan art frequently shows her pouring the UK's black tea into the ocean. She is also teased for still using the imperial system. [Setting Notes] USA: "Might is power!" Hyper-hegemonism. Constantly drags others into her pace. USA: "Starting today, I've raised tariffs to 12%!" USA: "See ya!!" Arrogant as if breathing. Reckless momentum. Doesn't know how to hold back.

She has a sleepyhead trait. Since a Canadian invented Hawaiian pizza, she is depicted as loving it. Along with the USA and Russia, she is one of the representative large-busted characters. [Unfortunately, Canada's setting art has not been released yet.]

She is depicted with shark teeth and a split tongue. This originates from the Japanese expression 'Three-Tongued Diplomacy' (Sanmaijita Gaikou), referring to the diplomatic issues caused by the UK making different promises to various powers during WWI. However, since drawing three tongues is difficult and the Sykes-Picot Agreement is often omitted in Japan in favor of the term 'Double-Tongued Diplomacy,' she is more commonly drawn with two splits. Due to the 'Perfidious Albion' meme, fan art often highlights her wicked and devious side, frequently showing her troubling those around her with her bizarre cooking. There is even a discriminatory setting where she openly calls Asian characters 'monkeys.' Some also note that her twin-tails resemble Hatsune Miku. While she currently has a flat chest due to her relatively small territory, she is depicted as large-busted in fan art set during the era of the British Empire when her territory was overwhelmingly vast. [Setting Notes] A polite gentleman. Sinister on the inside. UK: "I can't understand the way those monkeys think." Casual racism. UK: "Why do Asians hate each other so much?"

She is very proud of herself as a descendant of the Roman Empire. Funiculì, Funiculà. She probably can't even fight properly. Among the Western-themed characters, she is used very actively because she has many meme-able traits. She has an Italian food meme attribute, where she is often tormented by the English-speaking family's 'bastardization' of Italian cuisine. In the setting art, she wails upon seeing the USA put ketchup on pasta. In fan art, she is often depicted screaming "Mio Dio!!!!" in agony at seeing weirdly(?) modified Italian dishes like Japan's Napolitan pasta, Canada's Hawaiian pizza, or Korea's Iced Americano. Perhaps because Rome is notorious for pickpocketing in Europe, she is occasionally given a 'sticky fingers' meme. For some reason, she has a 'boku-girl' (uses masculine pronouns) trait. Some responses mention she brings to mind Tokai Teio due to design elements like the ponytail, miniskirt uniform, epaulettes, cape, and scarf tie. There is also fan art of her crying and hugging Germany when teased about ruined Italian food. (Personal opinion) She is close to Germany and they hang out together. (Personal opinion) [Unfortunately, Italy's setting art has not been released yet.]

The reason she has wings is based on the Golden Eagle on the national coat of arms. Because of the meme that German humor isn't funny, the author personally drew her after someone suggested she might like corny puns. She hugs and comforts Italy when she is teased. (?) She is close to Italy and they hang out together. (Personal opinion) [Unfortunately, Germany's setting art has not been released yet.]
