Cute Bruiser: She seems to like to punch the people who are the target of her anger, and unlike her male counterpart, is said to display great physical strength when she becomes emotional.
Fan Nickname: She's often given the name "Feliciana" by the Western fandom as her human name, whereas the Japanese fandom seems to prefer "Alice" (pronounced as "Ah-LEE-che") judging by how quickly the Pixiv tag for the name filled up after Himaruya mentioned that someone suggested the name to him for female Italy (Before that, the popular Pixiv tag was "Daisy Vargas").
Fan Nickname: Both Western and Japan fandom commonly call her "Louise" or "Luise" as her human name. Some fans also opt to use "Monica", an unofficial name suggested to Himaruya for female Germany, instead.
Letís just calmly go somewhere safe without aiming the bat at anybody.

A-Cup Angst: She appears to be rather flat-chested compared to many other nations on this page, and many fanworks have her being self-conscious about her lack of assets compared to other female nations'.
Fan Nickname: "Sakura" is the most widely accepted fanon name for her in Japanese fandom, and it was in fact suggested to the artist. Many Western fans, however, continue to use "Kiku", the human first name the artist gave to her male counterpart, for her because Kiku can also be a female name.
Fan Nickname: Fans from the Western fandom have often given her the name "Amelia", "Amanda", "Abigail" (shortened to "Abby") or "Allison" (shortened to "Ally"). However, the Japanese fandom seems to prefer the name "Emily" for her.
In-Series Nickname: In the strip where the genderbends appear, she is called (what is translated to) Americako. Most of the fandom, however, simply call her "Ameriko".
Fan Nickname: Both Western and Japanese fandom have given her the name "Alice". And though unofficial, Himaruya had mentioned in his blog that someone had suggested the name "Rosa" for England. Western fans may also call her "Rose", "Ann", "Elizabeth", "Rosemary" or "Audrey". Some people prefer to call her "Guinevere", referring to King Arthur's wife.
Fair Cop: Her P2 design has her wearing a Mountie uniform.
Fan Nickname: Western fandom seems to prefer "Madeline" (shortened to "Maddie") as her name. Also, Himaruya had said on his blog that a fan had suggested her name be "Marguerite" with her nickname being "Meg" for short; this name is unofficial.
Boobs of Steel: Subverted. Romana has been said to be a better fighter than her male counterpart, but a group sketch shows she certainly doesn't have big breasts. Fanon on the other hand loves to play this trope straight.
Fan Nickname: She is often given the name "Lovina" by most of the Western fandom. Japanese fandom, however, calls her "Katarina" or "Catalina". According to Himaruya, a fan had once suggested for her name to be "Chiara". The name, though, is unofficial.
Girly Bruiser: Is very feminine, but she's a better fighter than Romano.
Fan Nickname: Her most popular "human names" among fans are "Giselle", "Gisela" or "Maria". "Gretel" also isn't unheard of.
Himaruya had mentioned once that a fan suggested for "Julchen" to be her human name. However, as "Julchen" is an affectionate nickname based on the name 2Julia", fans tend to opt for the whole name instead.
Fan Nickname: Japanese fandom has given Hungary's male counterpart the names "Daniel", "Hendrik" or "Elian". Western fans usually just shorten his country name to "Gary"; "Mangary" is in fact a common term used for him.
None of which are Hungarian names. (Daniel is the only one that has a Hungarian cognate.)
Keet: He appears to be this in an earlier group sketch.
Yandere: Pixiv fanart picked up on this a bit even before the first day he was revealed finished. One can also assume he's yandere for fem!Russia, but YMMV. The type of yandere tends to differ, though: contrasting with the canon Belarus being "let's get married, let's get married, let's get married, LET'S GET MARRIED" (obsessive type), male!Belarus tends to be more passive-aggressive and say "I'm the only one good enough for you, Sister, so let's get marriedmarriedmarried" instead (possessive type).
