MS-11 Action Zaku

The MS-11 Action Zaku, often referred to as Act Zaku for short, is a Principality of Zeon prototype mobile suit from the Gundam anime series. The Act Zaku had appeared in some animated form (such as Zeta Gundam), and it is an official MS-X mobile suit variation. It is based on the MS-06 Zaku II

Combat Characteristics
Built under the Pezun Project at Zeon's Pezun space asteroid base, the Act Zaku was planned to be a new mass-production model mobile suit that the Zeon would field to sway the tides of war back into their favor. The Act Zaku was the testbed for the new "magnetic coating" technology developed by the Zeonic Company. The special magnetic coating materials were applied to the joints of the Act Zaku, which could be electrically charged to produce a magnetic field. This field caused the components of the joints to repel one another, reducing the friction caused by joint movement to almost nothing, creating a faster and much more responsive mobile suit.

The Act Zaku was also designed with a much higher output reactor, allowing it to wield beam weaponry. A custom beam rifle was in production for the Act Zaku to use. However, the design for the weapon was not complete by the time the Act Zakus were deployed, so they were issued machineguns instead. The Act Zaku was also issued a heat tomahawk for use as a melee weapon.

History
The Act Zaku was introduced too late for the Principality of Zeon. Some units might have actually seen combat during the retake of the Pezun asteroid after the end of the war, quite possibly already equipped with beam rifles. When the Earth Federation Forces captured the Pezun asteroid, they obtained the designs for the Action Zaku, and the concept of magnetic joint coating. The Earth Federation would put the Act Zaku into production for their own use after the One Year War.
