The MS-18 Kampfer was a prototype mobile suit created by the Principality of Zeon in the anime series Mobile Suit Gundam 0080: War in the Pocket, designed by Yutaka Izubuchi. For the figure Zeonography, it is redesigned by Katoki Hajime. In the few remaining days and weeks before the end of the One Year War, the Principality of Zeon churned out several new prototype mobile suits. One of these new units was known only as the YMS-18 Prototype Kampfer, which Zeon engineers quickly began producing different variations and redesigns to create custom units meant to excel in specific mission roles. One of the variations created was the MS-18E Kampfer ("Kampfer" being the German word for "fighter").
The "E" in the MS-18E Kampfer's model number was an abbreviation for the German word "einhauen," which translates to "one strike." "One strike" summed up the Kampfers role in combat as a fast assault unit. It was meant to strike quickly, cause massive damage with its varied weapons loadout, and make a fast escape. The Kampfer was a very focused design, never intended to work outside of its created role. Within this role it was an exceptional unit, rivaling the Federation RX series in firepower and speed. The unit was covered with thrusters and verniers to give it high maneuverability. Conversely, the large number of thrusters resulted in a high fuel consumption rate, limiting it to only being operable for short periods of time. Its designers chose only minimal armor plating, even removing the hip mounted skirt armor found on most mobile suits entirely from the design. The choice of conventional explosives and weapon systems in favour of beam weapons was made to reduce the drain on its powerplant and resultant drop in speed. Weapons racks were designed to be ejected from the unit as they were expended, minimizing dead weight. The unit was intended to be operated by special forces, built to be easily disassembled and reassembled in blocks. This was to aid in its insertion and activation behind enemy lines.
