Gregor has a bald head showing cheekbones and a wrinkled forehead. He has normal Tan colored pants with no printing and has a normal blaster accessory. He has a sleeveless shirt colored light grey with the Power Sliders logo on it and has a white belt.
Gregor was a Republic Commando who fought in The Clone Wars. In an engagement against the Seperatists, the Republic was disastrously defeated, and Gregor was traumatized and lost his memory. He then found his way to Abafar on a shuttle and came to work for a diner called Power Sliders. Eventually a squad of droids working for the Republic crashed on Abafar and helped Gregor regain his memory. To escape the planet, the squad infiltrated a Seperatist airbase and stole a shuttle, with Gregor staying behind to cover their escape. He did not die however, and somehow removed his inhibitor chip and lived on Seelos with Captain Rex and Commander Wolffe when the Spectres visited them. After fighting off the Imperial invasion, Gregor and Wolffe stayed on Seelos while Rex decided to join the Rebels.
