The MSM-04 Acguy is from the Universal Century timeline of the anime Gundam metaseries. Following Zimmand Company's MSM-03 Gogg, the Zeonic Company produced their own amphibious mobile suit for the Principality of Zeon, the MSM-04 Acguy. Acguys used many of the same parts and components as the MS-06F Zaku II, including twin Zaku II F-Type Minovsky ultracompact fusion reactors. However, even with the twin reactors, the Acguy left only a trace heat signature, making it effective for stealth operations.MSM 04 Acguy Papercraft
