Nyotalia

Nyotalia refers to the genderbent versions of the canon Hetalia characters, it's a fan-made term started by the Japanese fandom. Nyo deprives from the words nyotaika (male-female genderbents) and Talia is a short reference for Hetalia or Italia. The characters who get genderbent are usually called Nyo!, Fem! (male-female) or Male! (female-male).

In addition, designs of the opposite gender exist for certain characters, as Hidekaz Himaruya drew them for fun to see what the nations would be like. However, Himaruya also noted that when drawing the characters, he came up with their designs as if they were completely different people (if they were designed as females to begin with). This is presumably why some of them lack certain distinguishing details that their original versions had. However, their personalities mostly remain the same.

Female North Italy
Female North Italy mostly inherits her male counterpart version in terms of appearances; she has a curlier and lighter brown hair that is tied into a ponytail with a curl sticking out from the left side of her head, she has the same brown eyes that appears to be more amber and is opened more times than her canon version. If look closely, there's a bandage on her left knee. She usually wears a short khaki shirt with a skirt of the same color, a black tie, a belt, a pair of brown gloves and a pair of golden brown leather boots.

Himaruya described Nyo!North Italy as strong, unlike her "useless" male counterpart as she can display an unusual bout of physical strength when angered. She had also argued and throw punches with Nyo!England, to an extent that she is the braver one and more willing to fight. As shown in her bandage on her left knee, she's more unaware of accident proneness and is rougher than her canon version.

In a blog post, Himaruya had mentioned that he liked the name Alice for female Italy, commonly pronounced as "Ah-LEE-che" in Italy, from a list of names he was sent for some of the Nyotalia characters. Itako is a nickname for the female version of Italy, derive from Itaria and the suffix "-ko". Though fans in the Western fandom tend to use the names Felicia or Felice for her, the Japanese fandom has given her the name Daisy Vargas. This name had fallen out of use shortly after Himaruya brought up the suggested name Alice. Alternatively, in a straighter "genderbend" take, Daisy is sometimes used as her middle name, with Feliciana being the first name.

Female Germany
Female Germany does not wear her blonde hair slicked back. In a group sketch, she is shown to wear only a tank top and pants when training, much like the male Germany. Two other sketches depict her wearing uniforms similar to her male counterpart's. Each illustration depicts her with a worried or exasperated expression.

In his notes, Himaruya described her as being reserved, serious like her male counterpart, and as having large breasts. He also said that she's tall and gives off a cool feeling. In a sketch, Germany was shown to be scolding a bruised male Italy for rashly getting himself into difficult situations.

Himaruya had once received a list of name suggestions for some of the Nyotalia characters, mentioning that he had liked the name Monica, the German variant being Monika, for Germany. Doiko/Dokuko are two names that are used to refer to the female version of Germany, which are both derived from Doitsu and the suffix "-ko". The latter is a pun on the kanji for Germany (doku) as well as a pun on the term bokuko (a girl that speaks and acts like a boy). She is also referred to as Nyoitsu, most notably on her Pixiv tag. In both Japanese and Western fandom, fans often use Louise, or Luise, as her human name.

Female Japan
Female Japan is depicted as to be the same height as his male version and has a bob hairstyle, and has shine to her eyes unlike her male counterpart, with them being more amber in the colored version. In Himaruya's notes, she is stated to be a Yamato Nadeshiko-type character who yearns for the West a bit.

She is usually not sketched in any sort of military uniform, but rather in a simple pink and purple kimono or other civilian clothes such as a school uniform. She seems to always have a shy expression, befitting of one with a Yamato personality. According to Himaruya, Japan used to have much longer hair in the past. She cut it to its current length after opening up her borders in order to prove she would be able to get along with the rest of the world.

Her fanon name has been given as Honda Sakura (or "Sakura Honda" in English-speaking order). When Himaruya noted that the names he was personally fond of (in female Japan's case, her common, fanon one) were not official, he mentioned that if he had chosen an official name for Japan, she "would for sure end up with a name like Ponko or Mameko". Nichiko and Nihoko are also names used by some of the Japanese fandom for the female Japan, from Nihon (or the kanji nichi) and the suffix "-ko".

Female America
The female version of America does not have "Texas" glasses or a "Nantucket" hair. She has blue eyes and wavy, honeysuckle-colored hair that comes to her shoulders, with two star-shaped barrettes holding her bangs out of her face

She often dresses in short skirts or shorts and wears tops which expose her midriff. In her initial design, she also wore a cowboy hat and boots and had an American flag patch on her top, though some fans mistook it for a tattoo on her chest. Her later design depicts her in a bomber jacket like the male America, though she seems to be fond of hot dogs instead of hamburgers. Her weapon of choice appears to be a baseball bat as she solves her problems through violence.

Female England
England, unlike canon England, has glasses. She no longer has the signature thick eyebrows, though Himaruya mentioned missing them, and wears her blonde hair in long pigtails that are either slightly curled or completely straight, not in a messy hairstyle such as her male version. In two coloured pictures of her, her hair appears to be the same colour as her male counterpart's original hair colour. Her eyes are the same colour of green.

This version of the character is called Igiko (girl England/UK) by Himaruya and Japanese fans alike. Himaruya describes her as trying to behave elegantly, but being quite punk. In an old post, Himaruya commented that being kuudere and that being the type to say embarrassing things smoothly might be nice for a female England. She is often depicted in a British schoolgirl uniform or the uniform of the female nurses of the NHS.

Female France
France's female counterpart is an elegantly-dressed woman with her hair tied back into a french knot, usually held back by a crown or something similar. She usually wears the upper part of a double-breasted military uniform with a matching black tie and gloves. She also wears a dark purple cape or cloak either shown as long or short; the lower part is a light purple or violet skirt, and it has been shown that she wears black or dark-colored stockings with knee-high boots. She is sometimes shown holding a bottle of wine, or a single red rose as an alternative. Her hair is dark brown (or alternatively a dirty blonde) and her eyes are violet.

A snobby woman, she is said to be more protective of Canada or his female version, as he used to be her former charge. She is also much more argumentative than her male counterpart.

Female Russia
Female Russia is a modestly-dressed woman with long beige-blonde hair. Her first seen picture gave her soft blue eyes while her second appearance gave her lilac colored eyes. Himaruya has described her personality as akin to a wearied mother figure who is emotionally unstable rather than childishly cruel.

In their appearance in Volume 4, Italy referred to her as the origin of all suffering, and demanded that she be nicer to Estonia, which prompted her to say that she'd spread honey on and rolled him around outside a little bit.

Female China
Female China usually wears some form of qipao dress and has her hair, now a deep auburn, tied up in a set of mouse buns. In her first appearance, her dress had short sleeves, but it was changed to a long-sleeved uniform by the time she appeared in another illustration. Rather than the wok and ladle her male counterpart uses, China is often shown holding a large square kitchen knife or meat buns.

Himaruya stated that he doesn't know what she's thinking well. It is said that she is a type of girl whose emotions cannot be read easily, but is most often depicted with a very similar personality as her male counterpart.

In her appearance in Volume 4, she attempted to sell Estonia a medicine, saying that if he bought it they would both be happy, after seeming to climb atop the back of his chair.
