Hak Son

Hak Son is one of the main characters from the Akatsuki no Yona anime and manga.

Hak as he was known at the beginning of the story, is the main hero and the former General and Chief of the Wind Tribe. He is an adopted grand son of Son Mundok, the adoptive brother of Tae-Yeon, and the childhood friend of Yona and Soo-Won. He is known throughout Kouka as the “Thunder Beast” due to his outstanding fighting skills. He helped Yona escape from Hiryuu Castle after Soo-Won killed Emperor Il.

Appearance
Hak is described as a tall, tough-bodied, and a very attractive young man(hot as hell) with sharp blue eyes. He has short, messy black hair with bangs hanging below his eyes. He has a well-built frame, cultivated from years of training and is super popular with girls, which makes Yona a bit agitated sometimes.

He wears a sleeveless blue overcoat seamed with bluish black hemlines over a royal blue robe with black collar and sash. He ties black ribbons in a crisscross pattern over the lower half of his sleeves to prevent them from getting in the way when he is fighting. Underneath his robe, he wears black pants and a pair of dark brown boots overlaid with more crisscross-patterned ribbons. Occasionally, he can be seen wearing a sledge hat when he is hiding his identity.

He always (apart from sometimes when in disguise) carries his signature weapon, a Chinese glaive-like weapon called a Hsu Quandao, most of the time with its blade draped in a white cloth held by a black strap.

Personality
Hak is a mischievous and loyal person who strives to protect Yona at all costs and has been shown to be self-sacrificing, both physically and emotionally, when it comes to her well being. He has a habit of being a bully and likes branding some of the others, like Kija and Jae-Ha, with names. Despite being playful, he is serious whenever it comes to his job. His professionalism extends to a point where he addresses his childhood friends by their status. His devotion to his job stems from his belief in Emperor Il. At first, he had no intention to get involved in the royal family, as he saw it as troublesome. However, when he witnessed the emperor’s bravery, he swore loyalty to them, seeing that he couldn’t leave them alone.

When it comes to his heart, Hak destroys his impulses every time they resurface, even though it hurts to do so. There are times that he will show his affection with teasing, but not much beyond that. However, when someone (particularly Jae-Ha) questions the emotional distance between Hak and Yona, Hak loses his composure and can become territorial around the princess. He seems cold around Yona at first, but slowly reveals that he truly cares deeply for her.

Abilities
Martial Skills: Hak's skills with the Chinese Guandao polearm are the best in the country. His speed and strength allow him to deal powerful blows, even sweeping aside a large area of fog with one swift strike. Aside from his mastery with a glaive, he is also good in swordsmanship and archery.

Swordsmanship: While not his first choice of weapon, Hak is proficient with a sword and ultimately is the one who trains Yona in swordsmanship.

Archery: Hak is an excellent shot with a bow, able to shoot bullseyes and birds out out the sky with ease, even on horseback. He is also the person who mostly teaches Yona archery, though Yoon also contributes.

Immense Strength: He is noted to have unusual strength by numerous people, including the four dragon warriors.[9][10] Even without his weapon, he can deal strong blows with his fists. Due to his strength and abilities he was jokingly given the name "Black Dragon" and seen as the fifth dragon by the other four dragons. Although not a dragon blood, he matches the strength of other dragons easily.

Endurance: One of his more defining attributes is his stalwart heartiness, first shown when enduring a bite from a venomous snake when protecting Yona. That being said, this may be mostly due to his determination to live and protect Yona.

Basic Medical Skills: Though not as good as Yoon, Hak has shown to have a basic knowledge of medicine. He was able to remove snake poison from his system and he shows Yona how to remove thorns and disinfect the cuts she received from the Senjuso test.

Trivia

 * In the planning phase of Akatsuki no Yona, Hak’s original name was “Soron”. It seemed too similar to “Soo-won”, so it was changed to “Hak-jin”. In the end, it was shortened to “Hak”. The name "Soron" was later re-used as the name of Mundok's deceased biological son.
 * He ranked 1st in the character popularity poll conducted by Hana to Yume in December, 2014. He scored 3,001 votes in total.
 * According to the 2018 fanbook, his parents were casualties of the original Xing war 17 years prior to the start of the plot. He was orphaned at age 2, around the time Yona was born.
 * Hak often refers to himself as the fifth "Darkness" Dragon, in reference to a joke made by Kija that he would be an evil "Darkness Dragon" if he were to be one of the dragons.
