Krizalid

Krizalid is supposed to be the perfect Kyo clone. It was supposed to be achieved by cloning K' and not Kyo himself. Because of that Krizalid had some side-effects, like when Krizalid thought that Whip was his sibling.

He was ordered to activate all other Kyo clones. He was given a special suit, that collects the fighting data needed to activate the clones. To collect the data he fought the winning team of the King Of Fighters 99 tournament. He lost and was crushed under a rock by his superior, Zero.

Krizalid was later revived by the original Zero and Krizalid fought in the King Of Fighters 2001 tournament. It is unknown what happened to him after that tournament.
