He works for NESTS, a secret organization that held this KOF meeting. At first, he didn't realize that he had been transplanted with Cao Shajing's fighting ability. It all started when NESTS arranged K's intensive surgery. Originally, it was carried out to strengthen his original combat physical fitness, but the experiment of transplanting and transforming genetic factors was carried out secretly without K's knowledge. It may be that NESTS' transplantation technology is incomplete, or that K' has a problem and can't completely control the sudden super power. The special gloves for the right hand were developed by NESTS' technology array to give him SPPORT tools to control the outbreak of inflammation. Without this glove, Yan Xi will suffer all kinds of incalculable injuries and obstacles under uncontrolled circumstances. K's memory was tampered with by NESTS, leaving everything in his childhood memory blank. In order to make him feel the strangeness of blank memory, the part of the question has also been adjusted. After the operation, mysterious power gradually emerged from the body in a short time, and it was found that it was very similar to the power held by a man named Cao Tiaojing. As the only clue to find out the truth, NESTS will never allow him to do so, although he will try to investigate his connection with Cao Shajing. When he finally realized that he could not know anything about himself even in the organization, he decided to leave NESTS. I first went to the KOF conference as a staff member, and disappeared after betraying the Bird's Nest with Maxima. I have no news now. I don't like to see a group of participants together in a friendly way, so his mantra is "I'm lonely …", which has fully expressed his feelings. At the same time, he also hates the so-called "tactics" of those boxers. He thinks that there are only victories and defeats in any competition. Under the principle of "the winner is king and the loser is the enemy", he will only seek victory by hook or by crook until his opponent is completely defeated and cannot rise again. K's personality is gloomy, taciturn, unwilling to make friends, willful and self-centered. But there is also a confidant MAX-MA. That's his only friend. Although his personality is terrible, when k exceeds the limit, the explosive power can be said to be groundbreaking. If Cao Tiaojing is a masculine work, then K' is a powerful feminine figure. However, it is not as relative as Cao Tiaojing and Iori Yagami. Recently, it seems that K' is the balanced existence of Beijing. K is the first word in KUSANAGI. K' was a popular figure in king of fighters. Judging from the plot, KOF99 has become the focus since it appeared-defeating all fighters in one fell swoop. SNK seems to like k, too. KOF99' s boss Gully check was defeated by K's chain movement (moves) and saved by KOF2000' s boss 0 -0. In 2000, KOF saw fighters such as Terry of the Hungry Wolf and Malaysia of the Extreme Flow Team struggling to face zero-zero, and K' lit the flame of his fist again and defeated boss again; KOF200 1 narrowly beat zero, and it hurts even more. MAX2 overthrew the domineering crimson star and seriously injured commander NESTS. Ignace defeated it with Kyo Kusanagi (this boss can be regarded as the strongest one in previous kof); Later, in 2002, boss rugal (KOF94, 95, 98, 2002boss), who had a phobia of Ignes, was defeated by Kyo Kusanagi and Iori Yagami (the plot in Hong Kong was inconsistent with the official plot and was tampered with a lot); Until 2003, kof defeated rugal's son and daughter. In 2003, Boundless BOSS was defeated by Iori Yagami and Kyo Kusanagi. In terms of plot, although Ash, a new user in Cui Yan, was completely uninterested in K' in 2003, K' was still injured and fought against it for more than 400 rounds, and finally won (time is up). Personally, I don't think it's appropriate to say K is indifferent, but I just keep my mouth shut. If Malaysia and Terry hadn't helped him regain his confidence in KOF2000, he would have been buried at the hands of 0-0, and he had an unspeakable feeling for Kula. Some people say it's love, others say it's affection, because the official didn't say it, and it also set a suspense for readers. In the unofficial plot of KOF2002 (Hong Kong Man), both Maksima and Kula were captured by Rugar. K gnashed her teeth and shouted, "If anything happens to them, I will kill you with my flame, Rugar!" In the snow battle of KOF in 2003, K narrowly defeated Li Caojing (1999, NESTS replica version, Cao Jing No.0, 1999, the official story saved Kyo Kusanagi, so after 2000, Bai Kyo Kusanagi was the real Kyo Kusanagi, and people may always think that the real Kyo Kusanagi was rescued by the influence of Hong Kong in 2002). In fact, Cao Shajing's challenge to Kyo Kusanagi was caused by excessive brain cell damage during the war (it seems to be a common problem of copying Kyo Kusanagi), and he was not killed by K'. The last boss in kof2003 was jointly killed by KUSANAGI and Ba Shen (this pair of old enemies is actually the perfect partner in king of fighters Chronicles). However, it is worth mentioning that after the war with Li, people who share the same fate with themselves go to Li's grave every year after their death. It can be seen that K is not an indifferent person.
