- “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.
In 1 BBY, Gregor and Wolffe were still living in the repurposed AT-AT walker, which had been christened Joopa Base. Gregor and Wollfe's modifications included a landing platform on top of their walker. Prior to the Liberation of Lothal, Hera along with Rex and the former ISB Agent Alexsandr Kallus traveled to Seelos to convince Gregor and Wolffe to help Ezra liberate his homeworld from the Empire. Gregor and Wolffe were joined by the Weequay pirate Hondo Ohnaka, the Ugnaught Melch, and the Mandalorian bounty hunter Ketsu Onyo.
Despite the small chance of success, Gregor and the others agreed to help Ezra liberate Lothal. After traveling through the Imperial blockade, Gregor along with Rex, Wolffe, and Kallus helped the Spectres and Ryder Azadi's Lothal resistance to defeat Governor Arihnda Pryce's forces at the Lothal cliff dwelling.
Last stand on Lothal
- “It was an honor to fight with you for something we chose to believe in.”
- ―Gregor's final words to Rex[src]
Following the capture of Governor Pryce, Gregor along with Rex and Wolffe took part in the assault on the "Dome", the Imperial headquarters on Lothal and a mobile Imperial Planetary Occupation Facility. For the operation, the rebels traveled in two captured patrol transports. Using an unwilling Pryce, the rebels gained landing rights for the executive landing pad at the Dome. After a brief battle, the rebels managed to capture the command center and initiate a faux Protocol 13, causing the entire Imperial garrison on Lothal to evacuate aboard the Dome.
Before they could fire up the Dome's thrusters, Grand Admiral Thrawn returned aboard his Imperial Star Destroyer Chimaera and blocked their exit. Thrawn managed to force Ezra to meet him aboard the Chimaera by bombarding Lothal's Capital City. In Ezra's absence, the rebels embarked on Sabine's plan to recapture the power terminals powering up the Dome's deflector shield generator in order to protect Capital City from Imperial bombardment.
Gregor along with Zeb and Kallus were assigned to Team B, which was tasked with recapturing and restarting the south tower's power terminal. Despite fierce resistance, Team B managed to reach the south tower. There, they were attacked by Thrawn's Noghri assassin Rukh and several Death troopers. While Zeb fought Rukh, Gregor and Kallus dealt with the others. During the battle, Gregor was shot in the right side of the chest by an Imperial weapons technician. Despite being mortally wounded, Gregor hurled the Imperial into the depths of the reactor chamber. He then told Kallus to get the shields back up. After reuniting with Rex, who had helped restore the north tower's power terminal, Gregor told Rex it was an honor to serve him before passing away. The rebels went to liberate Lothal from Imperial rule at the end after the purrgil attached themselves to Thrawn's Star Destroyers and dragged them into hyperspace.
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.
