- “Why spoil the fun? We haven't been shot at in years.”
Serving with an elite squad, Gregor was reported missing in action at the Battle of Sarrish, one of the Republic's greatest defeats. After escaping the carnage, his ship crashed on the planet Abafar, where an amnesiac Gregor was rescued by local diner owner Borkus, who gave him a job as dishwasher, his only pay being room and board in a run-down apartment.
He was later recruited by Republic colonel Meebur Gascon and D-Squad, a droid unit led by R2-D2, after they assisted him in regaining his memory. He in turn helped them escape Abafar, but was left behind on the planet and triggered a massive Rhydonium explosion to help cover their escape.
Though he was thought dead, Gregor survived the explosion. However, his mind was damaged, causing him to have brief moments of mild insanity. Later, after his friend Fives died trying to convince him that there are control chips inside all the clones heads, Rex soon did some investigating, and found out the truth. He later convinced Gregor and Wolffe to remove their chips as well, preventing them from executing Order 66. The three troopers never betrayed their Jedi Generals as their brethren did.
After the Clone Wars ended, the Emperor retired all the Clones, believing they have served their purpose. Gregor, Rex and Wolffe then spent their retirement on Seelos in a All Terrain Tactical Enforcer and occasionally hunted Joopas for food.
Meeting the Rebels
One day, while trolling the grounds of Seelos, Wolffe was introduced to the Ghost Crew, who were sent by Ahsoka Tano to acquire locations of Outer Rim bases for the Rebel network. When Kanan Jarrus identified them as clones, Wolffe, in turn, recognized him as a Jedi and let off a few shots. Gregor eagerly raised his rifle but Rex calmed the situation. When Ezra Bridger explains that they were sent by Ahsoka Tano, Rex welcomed them as friends. Later on, Gregor encouraged Garazeb Orrelios to help the clones hunt for joopas. But he later reveals to Ezra that Zeb was in fact the bait, resulting in the Lasat being swallowed by the joopa, whom Gregor nicknamed Big Bongo. After managing to kill the joopa, Zeb was none to happy to learn that he was bait, but was calmed when Gregor pointed out that he helped catch Big Bongo.
While settling down for dinner, Sabine Wren discovered that one of the clones, Wolffe, had contacted the Empire. While Gregor and Rex had grown to trust the Ghost crew, Wolffe wanted to protect his comrades from being persecuted by the Empire for harboring these rebels. When confronted, Wolffe admitted his wrongdoing and accepted Rex's reasoning that the rebels were their friends. After discovering and destroying an Imperial probe droid, the clones and rebels prepared for the impending Imperial assault. While Ezra tried to convince the clones to come with them, Rex was adamant that he and his comrades would stay behind to hold the Imperials back while the rebels escaped.
The rebels reluctantly departed in the Phantom to rendezvous with the Ghost in space. Shortly later, a force of three AT-AT walkers arrived, led by Agent Kallus. While outnumbered and outgunned, Gregor and his companions faced off against the Imperials in their lone AT-TE walker. At Ezra's urging, the rebels returned to rescue the clones. Gregor disabled a TIE Fighter with a well-aimed rocket shot, and together the rebelsand clones succeeded in defeating the Imperial force, forcing Kallus and his men to flee into the desert. After that, Gregor and his fellow clones saluted Kanan and his Padawan, and Rex agreed to join the Rebellion whilst Gregor and Wolffe stayed behind on Seelos, taking the remaining AT-AT walker for their new home.
Personality and Traits
Despite experiencing a brief spell of amnesia during the Clone Wars, Gregor was loyal to the Galactic Republic and willing to put his life on the line for it. Since Gregor removed his control chip, he was unaffected by the transmission of Order 66. Due to the brain damage he had sustained during the Clone Wars, he experienced occasional periods of insanity during the Age of the Empire. Despite this, he remained a skilled combatant, whether serving as part of his AT-TE crew or wielding weapons such as his RPS-6 Rocket Launcher.
Unlike Wolffe, Gregor along with Rex were not hostile towards Kanan and his rebel comrades. He befriended Ezra and Zeb, and convinced the rebels to accompany him on a hunt for Joopas in return for Rex supplying them with information on former Republic military installations. Gregor and Wolffe were loyal to Rex and looked up to him as their leader. Gregor and his fellow clones were filling to fight to the death in order to protect their new-found rebel friends from Imperial forces led by Agent Kallus. Gregor and his fellow clones came to respect Kanan and Ezra after the rebels came to their aid and drove off Kallus' forces.
