K' (ケイ・ダッシュ Kei Dasshu, pronounced K Dash) is the second protagonist of the games since The King of Fighters '99. He is a young person who lost all his memories when the NESTS syndicate captured him and inserted Kyo Kusanagi's DNA into his body so that he could copy his fire abilities. K', wanting to prove himself in being his own identity, betrays the syndicate and decides to destroy to them for using his body and deleting all of his memories. Although he hates fighting tournaments, K' uses the The King of Fighters competition as a way to find those who are associated with NESTS so that he can defeat them in an instant. In his search, he also meets a person named Maxima who has the same purpose and become partners with him. Yuuki Matsuda voices him in Japanese, while Andrew Scott is his English voice actor.
