Anti-K' Project

The Anti-K' Project was an experiment to counter K'.

Story
After K' and Maxima's betrayal at the end of The King of Fighters '99, NESTS began working on ways to take out the traitors. Due to how powerful K' was, the answer was to fight fire with fire; or in this case, ice. Learning what they knew about the K' program, NESTS created the Anti-K' program; an experiment that alters the users DNA to control ice. Their experimentations culminated by using a little girl who was kidnapped by NESTS at a young age. This little girl would become Kula Diamond; their "Anti-K'." Despite the fact that Kula was a mindless puppet with no sign of emotions (aside from being an innocent young girl), the NESTS cartel was not willing to repeat the same mistake they made with K'. Therefore, NESTS created an android called Candy Diamond, who would monitor Kula's behavior and assure that Kula would accomplish her missions, providing assistance in battle if she was needed. NESTS also assigned two of their top agents, Diana and Foxy to supervise and prevent any sort of betrayal by Kula.

Isolde was also a part of the Anti-K' Project; however, her abilities were deemed to be lacking and she was marked as a defective experiment. During this time, she met Nameless in the infirmary after he had suffered severe injuries in a mock battle to assess combat data. Meeting him greatly improved her impaired capabilities and thus she was allowed to see him again on a regular basis to nurture her powers.

Unfortunately, Isolde died during one of her tests. NESTS did not want to waste their progress on Isolde, so her essence was infused into the glove Nameless wears to help control his flames. Once Nameless learns of this from interrogating a fugitive of the syndicate, he works for NESTS with the hope of one day restoring her to her original body.
