Double-Fake Under The Gundam(ダブルフェイク アンダー･ザ･ガンダム?) is an original Gundammanga created by Yuji Ushida, originally published in Bandai's Model Journal magazine. After the story was completed it was compiled under the title Double-Fake: Under the Gundam.
Taking place in Universal Century 0090, between Mobile Suit Gundam ZZ and Mobile Suit Gundam: Char's Counterattack, the story centers on Darry Neil Guns, a member of the Monotone Mouse Corporation. While repairing Texas Colony at Side 5 -one of the colonies still damaged from the One Year War- the New Summer Project terrorist organization's Colorde forces attack. The anti-Earth Federation militant group Colorde, and the New Summer Project, were actually being used as a front for the resurgeance of the Second Neo Zeon movement under the leadership of Char Aznable. To combat Colorde, the Monotone Mouse Corporation is forced to team up with the Earth Federation Force's Arahas force and fight. Darry Neil Guns, fanboy of Gundam, modifies his worker mobile suit to appear to look like original RX-78 Mobile Suit Gundam. Through mistaken identity it is acknowledged as the actual Gundam.
