Gundam Pilot Mobile Suit XXXG-01SR Gundam Sandrock Pilot(s): Quatre Raberba Winner Production Site: L4 Colony Cluster The Gundam Sandrock, created by Instructor H using the resources of the Winner family, is the fourth of the Gundams sent to Earth in Operation Meteor. This powerful, heavily-armored mobile suit is perfectly suited to the desert environments of the Winner family's Middle Eastern homeland. Its regal appearance also suits the noble heritage of its pilot, Quatre Raberba Winner. The Sandrock's primary weapons are its massive heat shotels. Thanks to its sheer power, the Gundam can wield one of these huge curved swords in either hand and strike with both simultaneously. The heat shotels can be combined with the Gundam's backpack and shield to form an immense pincer weapon called the "Cross Crusher." Though it's fearsome at close quarters, the Sandrock's only long-range weapons are the homing missiles in its shoulders, supplemented by the standard head vulcans.

Gundam Pilot Mobile Suit XXXG-01SR2 Gundam Sandrock Kai Pilot(s):Quatre Raberba Winner When Gundam pilots Quatre Raberba Winner and Duo Maxwell attempt to return to the space colonies to thwart OZ's evil machinations, Quatre is forced to self-destruct his Gundam Sandrock to buy time for their escape. The Sandrock is subsequently reconstructed by OZ, then captured by resistance fighters who return it to Quatre. When Quatre returns to space once again, the Sandrock proves poorly suited for space combat, and master mechanic Howard takes it upon himself to upgrade Quatre's Gundam for use in space. The remodeled Gundam Sandrock Kai (or "Custom") features improved thrusters and additional manuevering verniers, to improve its space mobility. However, the modified backpack can no longer be used to form the "Cross Crusher" attack. The Sandrock Kai's distinctive heat shotels remain its primary weapon, but it's now armed with a hand-held beam machine gun for increased long-range firepower. With his upgraded Sandrock Kai, Quatre goes on to become the de facto leader of the Gundam pilots, coordinating them in their battles with White Fang's mobile dolls.
