During the course of The King of Fighters '99, Kyo-1 and Kyo-2 were merely two of thousands ready to be activated by Krizalid. They were presumably destroyed, since both characters don't have a personal ending and don't belong to any team. They return in The King of Fighters 2002: Unlimited Match as part of the Clone Team along with Kusanagi, only to presumably test their opponents and eliminate Kyo.
