The XXXG-01HD Gundam Derringer Arms is a Romefeller Foundation mass production Mobile Suit based on the XXXG-01H2 Gundam Heavyarms Kai. It appears solely in the semi-official one-issue comic New Mobile Report Gundam Wing Sidestory: Tiel's Impulse. Intended to operate within a set, small area, such as cities or bases, the design was refined to lessen its ranged combat abilities to save money. As a result, it features less weapons than its original counterpart as well as removing the blade antenna, lowering the overall range of its radar.
