Belarus

Natalia Arlovskaya (ナターリヤ・アルロフスカヤ, Nataariia Arurofusukaya; informal variant: Natasha ナターシャ, Nataasha) is a character in the series Axis Powers Hetalia/Hetalia: Axis Powers. She represents the country of Belarus (ベラルーシ,Belarushi).

Appearance
Natalia has long, platinum blonde hair, and blue eyes. She wears a long navy blue dress, a white hairbow (shown in one illustration to be on a headband), a white waist apron, and black shoes.

In her cameo appearance in Meeting Of The World in Hetalia: Axis Powers volume 1, her hair was colored light brown, and she wore a black hairbow and black dress (with no apron). Her hair also appeared to be drawn shorter.

In a sketch by Hidekaz Himaruya, she is shown to wear a deep green jacket, a long matching skirt, and black boots as part of her military uniform. Her bow headband is also colored black.

Personality And Interests
She is an intimidating, harsh young woman who has a deep infatuation with her older brother Ivan, to the point where she wants to get married to him. However, he doesn't feel the same way, and feels disturbed by her very presence.

Natalia is shown to carry around a knife at points, most notably in the "Meeting Of The World" strip where she's holding it to a traumatized Raivis's back as her brother scares him.

According to a footnote at the end of Russia's Big And Little Sisters in Hetalia volume 2, Natalia briefly became a sort of adoptive younger sister to Alfred after the fall of the Soviet Union. Her appearance as a Hetalia "desktop buddy" also reveals that she loves the occult, and that her favorite reading material was the Soviet newspaper Pravda.

Ivan Braginski (Russia)

Natalia’s older brother. Her love for him is as obsessive as it is unrequited, though much to Ivan’s dismay, the latter does not deter her. She is shown to stalk after him, as well as stick by his side to intimidate those who she feels might stand in their way.

In the Hetalia desktop buddies created by Himaruya, Natalia's obsession for Ivan is elaborated on even more, with her stating her desire to get suggestive photos of her brother.

Though Toris has a crush on her, Natalia despises him and has treated him harshly since they were children (having once broken his leg). When Toris did manage to go out on a date with Natalia, she broke all of his fingers.

In the Anime
Natalia first appeared in a cameo in Episode 01 so far, at the "Meeting Of The World", where she was seen holding the knife to a crying Raivis's back (as in the manga). She makes another brief cameo in a thought bubble in Episode 37, as Toris mentions that he planned to go out on a date with her. She finally makes her speaking debut in Episode 42, where she attempts and succeeds in breaking down her brother's door, in an attempt to get him to agree to marrying her. Her second speaking role is Episode 43, in which she insist that she'll stay by her brother's side forever. Russia thanks her, but Belarus adds that it would be better if they were married so that the relationship would be more intimate.

Her anime design originally had a color scheme similar to the one that she had in the manga version of the Meeting of the World strip, with her hair being darker and her dress colored black, rather than her hair being light blonde and her dress being navy. However, when she reappeared in Episode 42, the colors of her dress and bow were corrected, though her hair still remained dark blonde.

Trivia

 * Although her surname is often rendered and translated as Alfroskaya, the intention may have been for it to be read as Arlovskaya or Arlofskaya, as the katakana translates out to Arurofusukaya, which can be read as the latter. Alfroskaya would be rendered as Arufurosukaya. If read as Arlovskaya, the surname would correspond to Arlovski, like the Belarusian Andrei Arlovski. It is probable that he was not Himaruya's specific inspiration, though the other two surname spellings cannot be found outside of the fandom.
 * According to notes by Hidekaz Himaruya, Natalia was originally designed as a shy, more reserved character. An early headshot sketch shows her to have a plain headband, while her hair is colored light brown.
 * Though her name is Natalia, the Natasha name alternatively used for her is an informal variant of the girls' name and is also considered to be valid. Her first name may have also been intended to be spelled as Natalya.
 * Her birthdate, August 25th, corresponds with the date of Belarus's establishment of independence from the Soviet Union in 1991.
 * She appears in a concept sketch for Gakuen Hetalia.
