A Reploid soldier that fought for the former Neo Arcadia, and now the leader of the Einherjar Eight Warriors. He once saved the reporter Neige when she was attacked by a Maverick, and later fell in love with her. Kraft willingly joined Dr. Weil in order to guarantee Neige's survival. He believes that humans, including Neige, should not rebel against Dr. Weil, so that they survive.

Over the course of Mega Man Zero 4, Craft was touched by the words of Neige, and his actions became more drastic. He lost all respect for those that would accept Weil's rule without question, and rebelled against Weil himself. Due to the severity of his actions against the humans living in the former Neo Arcadia, Kraft was forced to do battle with Zero. Kraft was defeated aboard the satellite cannon, Ragnarok, which he was probably still on when it was destroyed.
