Kula Diamond/Story

Past
Kula Diamond is a little girl with an unknown origin. She was kidnapped by NESTS at a young age and was apart of the Anti-K program; an experiment that alters the users DNA to control ice. As a side effect of her surgery, her mental state has been turned back to that of a child.

The King of Fighters 2000
Prior to the events of KOF 2000, NESTS orders Kula to exterminate the cartel's traitor, K' during the tournament. Despite the fact that their subject 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.

During the midway point of the Tournament, she freezes an arena, trapping K' and his team. She is often ordered by either Diana or Foxy to exterminate K'. The two fight, and K' came out the victor, forcing her to retreat. Later, before Zero could fire a second shot with the Zero Cannon, Kula and Candy destroys it while in orbit. This causes them to be caught in the blast and falls head-first to Earth, but Candy sacrificed herself to save her beloved sister.

The King of Fighters 2001
The following year, NESTS orders Kula to enter KOF 2001, along with Foxy, Angel, and K9999, in the hopes of eliminating all of their enemies. When the K' Team went to the NESTS space base after winning KOF 2001, Foxy was attacked by Angel and K9999, critically wounding her. The two reveals to Kula that they were tasked to eliminate Kula and Foxy as the cartel sees the two as potential traitors. Kula escapes the two, and heads to the NESTS space base to find answers. After NESTS's destruction, she allies herself on friendly terms with her target, K' and his companions, understanding that both their lives were ruined by NESTS. Whip affectionately refers to her as the "little sister" of the group.

The King of Fighters XIII
Prior to the KOF XIII tournament, she was staying with K' and Maxima at their apartment. She became cellphone buddies with Chin Gentsai, who promised that she would get a lot of ice cream if she entered the tournament with her comrades. With Whip asking her to do the same, she entered herself and her teammates in the KOF XIII tournament.

Maximum Impact
Kula's life in this timeline is exactly the same as her mainline counterpart up until The King of Fighters 2003.

KOF: Maximum Impact 2
Kula accepts to enter in the tournament to search for Dr. Makishima under the orders of Heidern, as the doctor is needed to repair Maxima's failing nuclear core. During the tournament, she finds a rival in the form of Nagase, and defeats her, with the latter swearing revenge for the humiliation she suffered. Kula eventually discovers that the doctor had been taken elsewhere, and leaves the tournament.

The King of Fighters XIV
After an attack from NESTS operatives, Kula discovers that her ice cream was stolen. Refusing to let this go, she "convinces" K' and Maxima to join the upcoming fourteenth tournament.

SNK Heroines Tag Team Frenzy
Several months prior to the events of the fifteenth torunament, Kukri's obsession for women caused him to create a pocket dimension where women fighters must survive in his universe and join forces and slug it out with other women. Kukri transports most of the female fighters, including Kula, to this pocket dimension, and they suddenly fall unconscious. Upon waking, they find themselves in a strange mansion, along some male fighters who have been changed into women. The fighters attempt to battle their way out, but are confronted by the mastermind, Kukri, who reveals he has trapped them in his castle in a pocket dimension and they must defeat him to return home.
