Katana
Storyline of Katana
Often advertised as "The Ultimate Weapon", Katana is nothing more than deadly force. Using monofilament blades for hands, this unit can carve through a five-meter-thick wall of solid lead in less than ten seconds. Behind the blades are two very strong legs which allow the Katana to perform some amazing offensive maneuvers.

The Katana can jump, extending one arm upward, high enough to knock airplanes out of the sky. It can use its powerful legs to stomp on an enemy. It can also leap towards a wall, then use the force of the rebound to turn itself into a spinning mass of sharp steel.
