The Zaku 1 Stutzer was created by Zeon Remnants known as the Ausreiyers. In order to upgrade the only Mobile Suits they had availible, which were five horribly obsolite MS-05B Zaku 1s, they retooled them with stolen Federation parts and anything else they could salvage. The units are not compattable with beam weaponry so they are armed with standard heat hawks, grenades and long range rifles. The sensor systems have been completely rebuilt for much greater range and the cockpits have had extra monitors installed for better visibility. The armor and thrusters have been enhanced to allow for greater speed and defence. The power output has also been increased and is measured at 1311 KW. These Stutzers lack the winch units used by the other Stutzer models and have virtually no similarities to the Zaku 2 Stutzer. However it has it's own unique advantages. The chestplate has been simplified and reenforced for better protection. An external handle has also been placed on the chestplate and can be used to manually open the hatch from the outside in emergency. It also incorperates one of the earliest known wing binder systems. The binders are derived from the Zaku Flipper and serve as both an added thruster assembly and extra sensors that cover the Stutzer's rear incase of attack from behind. And the extra weight of the shoulder armor makes them well suited to pull off a ramming attack from either side. The new shoulder shields have been made from Gundarium alloy to reenforce the unit's ramming power. Titanium alloy has also been added to various parts of the body to not only strengthen the armor, but also lighten the overall bodyweight in various areas. Magnetic coating has been also been applied to all of the joints to give the units faster responce time. In ordor to compensate for the new operating speeds the units had to have upgrades done to their computers and operating systems as well.
In UC 0086 the Ausreiyers attempted to raid a Federation supply base but were met by a force of Titans GM Quel. Only one unit survived and was captured. It's pilot Phrank Stoker was imprisoned by the Titans to await trial. However The Gundam League and Tempest Zeon managed to rescue him before he was executed. He then joined Tempest and his Zaku reveived further upgrades. However Phrank had lost his taste for battle and prefered to use his Zaku for ship defense.
