Krizalid is the main antagonist from The King of Fighters' 99.
The NESTS cartel had watched carefully the King of Fighters tournament, in order to find the strongest fighter amongst all, deciding to get either Iori Yagami or Kyo Kusanagi. After the battle with Orochi, Iori disappears and Kyo is over exhausted. The cartel then kidnaps Kyo and get his DNA, but Kyo manages to escape his captivity and also disappears. The cartel then kidnap a man and infuse him with Kyo's DNA, naming him K'. K' is cloned, and his clone is then named Krizalid. Krizalid believed he was the original and K' was his clone. K's memories were erased, but he escaped from their control with the help of Maxima, another of their experiments. Krizalid is then ordered to create an army of Kyo Kusanagi's clones, which he pulls out in less than a year. Krizalid creates a special battle armor that he wears, which enables him to collect the battle data from anyone he fights, which was necessary to activate the clones.
Hosting the King of Fighters tournament, Krizalid watches carefully the teams and prepares to put his plans in action. He dispatches various troops in many key spots around the world while he awaits for the winning team to arrive at his laboratory. K' and his team make to his lab, so Krizalid challenges them to a battle. After the battle, he starts the activation of the clones by using the data fed onto his armor, telling K' that he is his clone. To get the trigger data necessary for the clones, he challenges K' once again. Krizalid is defeated, and the the voice of his superior talks to him. All of the clones are neutralized and the data he collected is sent to NESTS headquarters. With the order to terminate all operatives, Krizalid's superior toss a boulder on Krizalid, who falls unconscious as his lab starts to fall apart. Heidern picks Krizalid, who is unable to answer who he is, dying shortly after. Heidern's troops then hunt down K' and Maxima, who were labeled as terrorists due to their connection with NESTS, but they manage to escape the place.
Krizalid is cocky and megalomaniacal, but he knows his place, being loyal to NESTS.
