XXXG-01H2 Gundam Heavyarms Custom
An improved version of the Gundam Heavyarms, made more suitable for space combat. Not many changes were made, other than the mighty Gatling being replaced by the Twin Gatling Gun for extra destructive potential. The Endless Waltz version takes the upgrades a step further by removing the shield and knife, but adding a second set of chest guns, more missiles, and doubling up on the Twin Gatlings for a pair of them on each hand. Alternatively, the MS's colors change to a dark grey with dark green highlights. Its pilot, however, remains the stoic and collected Trowa Barton.
