From the manga "The Return of Johnny Ridden," the personal Gelgoog of Jacobius Nord, president of the private military company Themis, and the GM Quell piloted by its regular employees.
The Jacobius Gelgoog is based on a mass-produced Gelgoog kit, with a scratch-built backpack and a repurposed GM Sniper long-range rifle. Like the Yuma Gelgoog, the legs are a combination of junk parts, and the head and rifle scope are resin replicas of parts from a Zaku Forced Reconnaissance Type. The Themis decals were made by hand using "Decals at Home."
