Kyo-1 is a clone of Kyo Kusanagi created by NESTS. He first appears in the King of Fighters '99 as a playable character, and would eventually become part of the Kyo Clone Team in the King of Fighters 2002 UM.
Outside the game's universe, the game's developers wanted to see KOF '94 Kyo return to the game, but they were not sure which uniform he should wear. As time was running out, the project head told them to include 2 clones instead, and drew their designs on the spot, creating Kyo-1 and Kyo-2.
Both clones have been programmed to hate their original, Kyo Kusanagi, and serve NESTS loyally. Kyo-1 is basically more serious than Kyo-2 and never underestimates his opponents.
In M.U.G.E.N, Kyo-1 has been made quite a number of times by various authors. The most comonly used one is by Jin, and is supplied as part of a 2-pack with Kyo-2.
Kyo-1 is an absolute terror at close range. Many of his close range attacks, including his projectile and one super, have OTG properties. However, his long range capabilities are limited by the poor startup of his projectile.
