Ray Blade (レイブレイド Rei Bureido?) is the name of the rotating electrical traps in Mega Man Zero. It is possible, though difficult, to move between the electric blades. Though indestructible, they can be temporarily stunned by the Thunder Chip, or frozen with the Ice Chip. They appear in the Retrieve Data mission and in the Neo Arcadia Shrine.
Ray Blade also appears in one of Zero's attacks in SNK vs. Capcom: SVC Chaos.
