K'

K' (pronounced "kay-dash" or occasionally "Kay-Prime") was a normal child who lived happily with his sister, Seirah. One day, they were captured by NESTS, who trained K' to be some kind of weapon. His memory was tinkered with, and he was infused with Kyo Kusanagi's DNA, giving him the power of pyrokinesis. NESTS forced K' and Maxima to enter the 1999 King of Fighters tournament. After facing Krizalid at the conclusion of the tournament, the two left NESTS. The following year, they were allied with Vanessa and Ramon to discover NESTS schemes, but were interrupted by the appearance of Zero. Following the battle, K' and his sister, now called Whip, were reunited. Determined to take down the organization that ruined his life, K' and Maxima spent the next year destroying NESTS bases.

Following NESTS' defeat, K' becomes allies with former NESTS operatives Diana and Kula Diamond. He eventually came to treat Kula, the "Anti-K'" as a little sister.
