Technology & Combat Characteristics
A further development of RGM-111X Heavygun II by Anaheim Electronics (AE) engineers at the Granada branch, and a part of the Silhouette Formula Project. Besides having improved performance, the mobile suit also incorporated data from the F70 Cannon Gundam and could use the Mission Packs of the F90 Gundam F90 to a certain degree. The major drawback of the Proto Hardygun is that its operating system must be rewritten each time it equips a new Mission Pack.
History
In U.C. 0116, ten unit of Proto Hardygun is deployed to Luna II's 4th Aggressor unit in a simulation against the Fastest Formula Corps (FF). Some of these units were piloted by Karl Schwitz, Veronica Vernon, and Arthur Knightley, each equipped with parts from Formula Project's Mission Packs. During the battle the Proto Hardyguns manage to outperform the FF Corps mobile suits, including the F90 Gundam F90 Unit 2 piloted by Dir Rider using the Sea Serpents. However due to Dir's superior piloting skill, he cut the Sea Serpent and took down many of Proto Hardygun, resulting the lost of 4th Aggressor.
