Kyo Kusanagi

Kyo Kusanagi is the titular protagonist in SNK's The King of Fighters video game series. He was first introduced in The King of Fighters '94 as the leader of the Japan Team. He is the rival of Iori Yagami.

He was first introduced as a cocky delinquent high school student who is the heir of the Kusanagi Clan, one of the three clans that sealed the legendary snake entity, Orochi, 1800 years ago. His clan wields pyrokinetic powers, an inherited power that few members obtain. They, along with the Yasakani and Yata clans, keep one of the Three Sacred Treasures used to contain Orochi long ago. His family's treasure is the Kusanagi Sword, and his family crest is the sun, represented in a stylized halo of fire.

His official nickname is "Scion of the Flame"  or "The Cleansing Exorcising Flame".

Aside from the main series, Kyo also has a spin-off manga story based on his adventure in The King of Fighters '96, entitled The King of Fighters: Kyo. A video game under the same name was also created to further expand his character. In addition, a number of image songs and audio dramas featuring Kyo's character have been released, including the contents of his own character image album consisting of all of his theme songs. He is a member of SNK's character image band, The Band of Fighters and also co-star alongside Iori in one of SNK's promotional series, Part Time Stories: Kyo & Iori.

Development
When designing characters for the first The King of Fighters, developers wanted a new hip hero who would easily rival the Fatal Fury and Art of Fighting characters in style. Through most of his development, Kyo was meant to be called Syo Kirishima, and was dressed in martial arts clothing common with fighting games at the time. But late in production, his name became Kyo Kusanagi, likely due to the KOF story's change in direction towards the Yamata no Orochi legend. When designing Syo, Shinichi Morioka (Kyo and Iori's creator) used Shotaro Kaneda from the Akira manga as inspiration. When Syo appears as a striker in KOF 2000, he would be voiced by Mitsuo Iwata who also voiced Kaneda. The idea for his flames -as well as the other elemental powers for the rest of the Japan team- was derived from the anime Getter Robo; in the show, there were three featured heroes who served as the inspiration for the KOF trio: the protagonist had a "fiery" persona, his friend was "edgy and daring", and the third hero was the "down-to-earth giant". It is also a homage to a Japanese phrase of giving birth to fire (roughly translated as "lighting strikes the earth which sparks the flame"). Other influences include Jo Yabuki and Akira Fudo from the respectively series Ashita no Joe and Devilman. While in charge of designing the character, Yuichiro Hiraki sought to contrast Kyo with Street Fighter character Ryu, he considered the character to be an "overwhelming rival or a wall." He believed the latter was a popular character that couldn't be surpassed in the same field, so he made Kyo's characterization and design contrast Ryu so he could benefit from appealing to a broad demographic. He wanted Kyo to be a character who "dislikes training and was strong due to natural talent."

His change in fighting style was also made as a part of the series's overhaul in The King of Fighters '96. To appease all fans, they also included an older version of Kyo from The King of Fighters '94 into The King of Fighters '97 and placed the ' 95 version of Kyo in  ' 98, which made both versions of Kyo popular during location tests. The idea of having two versions of Kyo at once lead to the concept of his clones; during the early development stages of The King of Fighters '99, SNK planned to avoid adding any version of Kyo altogether, or Iori, to the game, as the story's focus was meant to center on the new protagonist, K'. However, they retracted this decision, as "they couldn't leave these popular characters in limbo". Since then, veteran developers for the series admit that Kyo's repeated appearances in the series is due to the marketers and the main planners' insistence to add him, Iori, and other SNK regulars in every game, making it a challenge to decide the story for each title. Kyo's voice actor, Masahiro Nonaka, related greatly with his character as being young and reckless until he "grew up" in his later appearances. He then expressed some difficulty accepting Kyo on the same level.



According to Nobuyuki Kuroki, the staff wanted to provide a new design that would captivate new fans. Despite Kyo being the main character, they decided to drastically change his hair and outfit. Fearing fans would not like Kyo's new appearance, the staff commented that they aimed it as a challenge, they also mention that old players from the series would understand he is still the same character despite cosmetic changes. This new design, alongside Iori's, provoked major controversy during the time it was revealed. However in an interview, The King of Fighters XIV director Yasuyuki Oda said the team wanted the characters to carry a new look due to the game being set in a new story arc. Oda also notes that Kyo became more macho as the games progressed, so they decided to alter his physique so he won't look as aggressive as he did in KOF XIII.

Kyo, along with his rival, Iori, has been noted by several of the series's designers as being one of the most difficult characters to illustrate because of his popularity amongst fans. In Gamest Mook Vol.197, Nona comments that he found it difficult to draw Kyo in a heroic image, since he draws Kyo in the image of Devilman's Akira Fudo.

Appearance
Kyo is often depicted as a young adult male with an athletic physique and a brown parted haircut. Since in his debut in KOF '94, Kyo sported a modified black gakuran, a Japanese male school uniform, as it appeared with his unbuttoned coat with the sleeves rolled up to his biceps and a vest, each with gold buttons, a tucked-in white shirt, a brown/gold belt and white buckled shoes. He often wears a large white headband to compliment this attire, along with a pair of his uniquely designed black fingerless gloves. Originally in KOF '94, each of his gloves were cut at the length of his wrists, with a single gold stripe marked around the areas of his palms. In KOF '95, while his gloves remain the same of his in-game sprites, his portraits marked a significant update, as the cut extends to midway of his forearms, another gold stripe added near the end of the cut, and an eclipsed sun crest near the area of his wrist. The sun crest is best known to represent the Kusanagi clan, which it also marked on the back of his coat since KOF '94. This outfit is considered Kyo's most recognizable look, often deemed this as his "classic" to the fans that it even makes the most appearances on crossovers featuring him. In-canon, Kyo prominently wears this outfit in the entirety of the Orochi Saga from KOF '94 up to KOF '98. Beyond in the main KOF series after KOF '98, some of Kyo's clones tend to wear this exact outfit in various colors, including Kyo-1 for a navy blue variant and Kyo-2 for a reddish-brown variant. This classic outfit also appears as an alternate costume in most KOF games such as KOF Maximum Impact, KOF XIII, and KOF XIV. Throughout the main KOF series, Kyo is known to change his outfits, depending on each arcs or on occasional new installments. Starting in KOF '99, Kyo discarded his iconic uniform for a more casual look that some fans refer this outfit as "Shin Kyo." His KOF '99 attire consists of a white jacket with black trimmings, a black shirt with a white hollowed cross, a pair of jeans with the rim of the sleeves slightly torn, a pair of black fingerless biker gloves, a small chain that hangs from the back pocket to the belt area, and black shoes. He also discarded the headband, as his Round 1 intro animation in KOF '99 presents him taking it off of his forehead and burn it from his hands. He prominently worn this outfit throughout the entire NESTS Chronicles, from KOF '99 to KOF 2002. This outfit also appears in Neo Geo Battle Coliseum, KOF Sky Stage, Neo Geo Heroes Ultimate Shooting, KOF XI, and KOF XIII, with two of the latter games as his EX form. In KOF 2003, Kyo has worn a black racer jacket with the Kusanagi crest marked on the back, white shirt, a pair of dark green jeans, brown shoes, and a long brown belt that hangs out from the side of his hip like a tail. He also worn his classic gloves, though only the single stripe at his hand area are visible, while the Kusanagi crests are hidden in his sleeves. Kyo would wear this outfit again in KOF XI. In KOF XII & KOF XIII, Kyo worn a variation of his 2003 attire, as he replaced the racer jacket into an unzipped black motorcycle jacket with silver metal studs, the dark green jeans into blue jeans, brown shoes into black shoes, and the long belt into a regular sized belt with a large silver buckle. He also had the pocket chain hanging at the side of his hip like his NESTS attire had. The Kusanagi crest on the back of his jacket and his gloves remains on this slight change. In KOF XIV, Kyo sported a half-zipped white leather jacket with four zipper pouches on the front and one on each sleeves, a black v-neck shirt underneath. blue jeans, a pocket chain, brown buckled shoes, a large C-buckled brown belt, and a pair of black fingerless padded gloves. His jacket also has a pinstripe variation of the Kusanagi crest marked on his back, and a on each of his sleeves. The most drastic change on this appearance is Kyo's haircut, which it is known as a commonly popular haircut for the teenage boys in Japan, as most refer to this style as "the J-Pop haircut." This unusual look on Kyo left longtime fans rather divisive, as the staff aimed to appeal to the new fans while making him look less aggressive than his previous appearances. It is noted that in the earlier trailers of KOF XIV and promotional images, Kyo's hair was miscolored in shiny black, which it added more bizarre reactions from fans to even go as far saying he was "nearly unrecognizable." In KOF XV, Kyo returns to his proper parted haircut. Along with that, his most recent attire is very similar to his appearance in KOF XII & KOF XIII, with the unzipped black motorcycle jacket with the Kusanagi crest marked on his back, white shirt, blue jeans, brown belt, and black shoes. However, this attire has some modifications, as according to the main illustrator of KOFXV, Tomohiro Nakata, he aimed to make Kyo's appearance as an amalgamation of some of his previous outfits. Most notably, he wears the white headband again since his classic school uniform attire, having the Kusanagi crest marked on each of the unzipped part of his jacket sleeves and a gold stripe each on a pair of fingerless biker gloves. This latest appearance of Kyo left many fans with an very positive reaction since in his reveal of the trailers for the franchise's most recent installment. This appearance also closely resemble his Extra Striker form in KOF '99, as he also worn the jacket, jeans and the headband altogether. In KOF Maximum Impact 2, Kyo sported a very unique look designed by Falcoon as it consist of a black and white leather jacket with red trimmings and a curved pinstripe marked at the back, a black shirt with a white racing stripe, a pair of two-toned leather gloves with a white side on the front of his hand and a black side on the back, black jeans, white belt, white shoes, and a chained small tasseled flag hanging behind with a white Kusanagi crest marked on it. In the Chinese CG animated web series, The King of Fighters: Destiny, and the mobile game based on the same name, Kyo's attire is very similar to his classic school uniform, but with some significant changes; his coat has silver buttons, quilted padding with brown straps on the shoulders, latch-on straps for the sleeves, and zipper pockets. He also added a pointed circular belt buckle, a pocket chain hanging on the side of his hip. and wears white sneakers instead of the buckled shoes. His iconic gloves were also redesign with the Kusanagi crest now on the area of the back of his hands, and two gold stripes are at the end. In the mobile dating simulator game, The King of Fighters for Girls, amongst various outfits depending on events, Kyo's main attire seems to taken inspiration of his NESTS saga attire, as of having the white jacket, black shirt, jeans, pocket chain, and black shoes altogether. His jacket includes black wing-like decals on the front, half of the Kusanagi crest marked on each of the sleeves, black straps near the open slits of the sleeves, and two white belts on the collar. He also wears his iconic gloves, but as of only the gold stripes on his hands are visible. It is currently unknown this attire contains the Kusanagi crest marked on the back as no existing artwork of his back turned confirming it.

Personality
Kyo is the over-confident but well meaning protagonist of the series, more interested in enjoying life than having to partake in any particular responsibilities. He is quick to dismiss subjects that don't interest him and will often carry out his actions with a devil-may-care attitude. Despite his seemingly arrogant and rude demeanor, he treasures his friends and family, enjoying their presence and particularly doting on his girlfriend, Yuki, who is a descendant of the Kushinada clan. Because of this, he can be quite protective of her, especially against the Hakkesshus.

His extreme disinterest in studies has led to his chronic inability to graduate from high school (which has become subject to in-jokes). Although he is confident in his poetic talent, most of his poems aren't considered to be good by his listeners.

Kyo takes his clan's responsibilities on a more personal level, disregarding ancient legends and predestined events as any reason for his actions. His strong sense of justice and his zeal to fight stronger opponents are what he believes to drive him to carry out his destiny. His rivalry with Iori Yagami is one of mutual hatred and was hardly spurred by their clans' history, and partly due to Iori's prior aggression. While he will fight Iori, he won't go as far as to kill him, being aware of his role as a part of the Three Sacred Treasures. When Kyo and Iori join forces, it is often begrudgingly and as a last resort solution to the conflict at hand, with seemingly no desire to seek lasting and mutual peace, particularly on Kyo's part. However, he will leave Yagami alone as long as Iori doesn't seek to antagonize him as usual, and will respect his actions, especially if it involves their clan responsibilities. It is for this reason Chizuru watches over both men, to keep both their rivalries in check.

Powers

 * Pyrokinesis - Due to his Kusanagi heritage, Kyo can control fire. He can create fire from thin air, create fire balls, deliver punches of fire, create pillars of fire and put his own body on fire. However, he is neither immune to other types of fire nor able to control other fires that he didn't create. Also, the flames he wields are nothing more than just ordinary fire: it does not have the mystical 'trapping' ability of Iori's purple holy flames.

Skills

 * Motorcycle Driving - Kyo likes to ride his motorcycle around the streets of Japan. Some official pictures depict Kyo driving a scooter.
 * Poetry - Kyo likes to write poetry as a hobby, though his poetry is generally not much liked by his listeners.
 * Ice Hockey - Although representing the element of fire, Kyo likes ice hockey.
 * Musical Instrument - Kyo is also an accomplished guitarist, as seen in The Band of Fighters

Fighting Style
Kyo fights using the Kusanagi style of ancient martial arts, a Japanese style of empty handed combat taught only to the Kusanagi clan members. Like most of the clan members in modern times, these are labeled as Method/Style with numbers; numbers that actually use alternate kanji different from their originals. These examples are 108 Shiki: Yami Barai (Method 108: Darkness Sweeper), etc. with "Reverse Methods" being stronger versions of other attacks such as Kyo's signature DM, Ura 108 Shiki: Orochinagi (Reverse Method 108: Great Serpent Mower) being an example. In some sources, this even applies to his "unnamed" normal attacks.

Kyo also knows Kenpo, and uses it in most of his normal attacks. Kyo's moveset emphasizes Kenpo from KOF '96 onwards, discarding his 108 Shiki: Yami Barai and 101 Shiki: Oboroguruma (Method 101: Hazy Wheel), instead focusing on two of the clan's other techniques, the 114 Shiki: Aragami (Method 114: Savage Bite) and 115 Shiki: Dokugami (Method 115: Poison Bite). However, Kyo adds varying amount of original followup techniques from these moves that range from kicks-to-elbow dropping attacks which are also types of notable moves in Kenpo. The names of these new moves are anything but vague and simple names (such as 402 Shiki: Batsu Yomi/Method 402: Punish Recital and 125 Shiki: Nanase/Method 125: Seven Rapids), possibly due to Kyo's taste for poetry.

Thus, Kyo is a strong combo character that takes a while to master as his moveset from KOF '96 and following games explodes to ridiculous levels. Mastering it though allowed players to more easily adapt to use other characters that had more diverse movesets. Kyo made way for archetypes with moves that not only had multiple inputs, but each followup had its own unique features. This would also pave way for powerful mixups and combos if pressure was well-setup. Story-wise, this was possibly due to his initial defeat by Goenitz, Kyo reformed his style into a more-offensive focus via his original followups from the Aragami and Dokugami.

In the original games (especially in KOF '95), Kyo followed the "Ryu and Ken" archetype with Iori, as Kyo's moves differ slightly from game to game in the same manner as Iori, mainly their Desperation Moves. Changes in KOF '96 and onwards made them vastly different from each other. Alternate versions of Kyo would retain his old movesets from older games for nostalgia's sake, though each alternate version would be notably different from game to game. The 100 Shiki: Oniyaki (Method 100: Ogre Baker) is the one technique both Kyo and Iori still share to this day.

In KOF 99 onwards, Kyo even applies more personal touches derived from his father's techniques of the Kusanagi style, via his Hikigane (Plowing Iron) mimicking Saisyu's Kamukakari (Divine Consult) and even adapting his father's Nata Guruma (Hatchet Wheel) attack in KOF: Maximum Impact 2.

In KOF 2003, Kyo, Iori, and Chizuru's LDM's are all named the San Shingi (Three Divine Arts), taking after their clans, destinies, and treasures. Kyo's San Shingi no Ichi (Three Divine Arts No. 1) however, is his SDM version Saishuu Kessen Ougi: Mu Shiki (Final Play-Off Secret Skill: No Method), as opposed to Iori and Chizuru's versions being original attacks.

In The King of Fighters XII and XIII, his default self switches back to his old KOF '94/'95 moveset. His Neo Max in XIII, the Ama-No-Murakumo (Gathering Clouds of Heaven) is a reference to the original name of his heirloom. His NESTS-Style version uses his traditional "Kenpo chain punch" moveset, and is given a Neo Max named Saishuu Kessen Hiougi: Totsuka (Final Play-Off Hidden Secret Skill: Ten Fists), a nod to the famous Totsuka-no-Tsurugi (Sword of Ten Fists). Another possible nod is his 182 Shiki/Method 182, a powerful flaming punch attack, which may be the finishing blow dealt by Kyo to Orochi in the Orochi Saga's end (though in some other games, the 182 has a different animation, while its SDM version in XIV is a combination of its two different animations).

Also, two other new moves in XIV that compliment his poetic taste are an overhead finishing move to his new low-attacking Munotsuchi (Six Mallets) followup from Aragami, and his Climax DM; they are respectively known as Tsurube Otoshi (Well Bucket Dropper; a term for sinking quickly) and Yaegaki (Double Fences; a term for fences over fences). The aforementioned Yaegaki is also very similar in motion to his father's SDM-version 1127 Shiki: Tsumugari (All-Eyes Reaper) as yet another nod to him, as it is Kyo's own "Reverse Method" version of it as well. The term "Yaegaki" also derives from the "Yaegaki no Tsurugi" (Sword/Saber of Doubled Fences), another name for his family's heirloom.
