This gundam paper model is EMS-05 Agg, a Principality of Zeon mobile suit from the anime series Mobile Suit Gundam, the papercraft is created by a Korean designer [name?]. Although it never appears in any animated series, the Agg is an official Mobile Suit Variation.
The Agg was constructed in preparation for the Zeon's upcoming assault on the Earth Federation subterranean headquarters of Jaburo. Built at California Base, it was one of a few highly specialized mobile suits that would aid in the assault. The Agg was designed primarily to bore and smash through rocks to create tunnels for other, more combat capable, mobile suits to enter Jaburo through.
The short and stubby Agg was equipped with two hover jets instead of standard legs, so it could float rather nimbly across the ground instead of walking. To efficiently cut through rocks the Agg featured two very large drills on its forearms, as well as a pair of large grinders on its shoulders, and a laser cutting torch on its torso. However, the Agg had virtually no combat capability, but its arm drills could be replaced by 4-tube missile pods and a 4-tube missile launcher mounted on its head to serve a more combat oriented role.
