Kula Diamond (クーラ・ダイアモンド, Kūra Daiamondo) is a character in The King of Fighters series. First appearing as the sub-boss and playable character in The King of Fighters 2000, she enters as a normal participant in subsequent appearances. Her original hair color is strawberry blonde (confirmed after the game's release), but changes to a light blue when she activates her powers. She's often seen with her companions, Diana, Foxy and (prior to her 'death') Candy Diamond. She was designed to be the antagonistic foil to K', in an attempt to better develop characteristics of the NESTS cartel. She was specially made with attempts to depict a 14-year-old girl with "appropriately girlish" gestures with help from the newly hired female staff. As her name "Kula" in Japanese katakana written as "Kūra", it reflects her icy powers as it sounds similar with "Cool" (クール, Kūru). Her official nickname in The King of Fighters XIII is Ice Doll.
