Gregor

Clone Captain Gregor held command of Foxtrot Group, a clone troopers squad belonging to the Special Operations Brigade and the 212th Attack Battalion. He at one point formed a friendship with Clone Captain Rex. Gregor and his squad of clone commandos were involved in the turbulent Battle of Sarrish, which culminated in a devastating defeat for the Republic. After covering the retreat of allied forces, Gregor was declared missing in action following the battle and presumed dead. Despite his best efforts, the entirety of Gregor's squad perished in the engagement.

However, Gregor had pulled through. His escape shuttle crashed on the planet Abafar in the settlement of Pons Ora, though he was not unscathed. Gregor experienced amnesia due to a severe head injury. Unable to recall his status as a soldier of the Republic Army, he sought employment and secured a position as a dishwasher and cleaner at the Power Sliders diner, provided by the Sullustan Borkus in exchange for mere room and board. He worked at the diner for an extended period, never recognizing his true identity due to his amnesia. Borkus seized his armor, weaponry, and other equipment, withholding his true identity from Gregor.

After Colonel Meebur Gascon and his team of droids crash-landed on Abafar while attempting to return to Republic lines following a mission, they eventually made their way into the town. While Gascon was looking for food, he encountered Gregor behind the diner. Gregor offered him food but was puzzled when Gascon attempted to inform him that he was a clone. Gascon began to suspect that Gregor was working undercover, and a disoriented Gregor left Gascon and later went home.

Later, Gregor returned home from work and was greeted by a hologram of his old friend Rex. Shocked, Gregor listened as Gascon explained who he was. When R2-D2 scanned Gregor's arm to learn his designation, CC-5576-39, Gascon read through Gregor's report, which listed him as missing in action. Gregor began to remember who he was, recalling the wounded and dying clones from the battle. Gascon convinced Gregor to search for his gear and help them leave the planet and complete their mission.

Gregor and his new companions broke into the diner to search for Gregor's equipment, but Borkus arrived with Gregor's gear in a large crate. When Gregor angrily accused Borkus of lying to him, Borkus pointed Gregor's own blaster at him. Gregor tried to reclaim it and clumsily lunged, still not functioning to his abilities as a clone commando. Borkus easily knocked him down, but was overpowered by the droids of D-Squad. Gregor then donned his gear and prepared to help D-Squad storm the landing pad at the Separatist Rhydonium mining installation.

Gregor fired on the hordes of battle droids, clearing a path for his allies but leaving himself surrounded. As hostile forces closed in, Gregor advised Gascon and his forces take off, leaving him facing near-certain death. Gascon reluctantly agreed and departed as Gregor promised that he would make his way home. Gregor seemingly sacrificed himself after shooting containers of rhydonium to destroy the droids that would have shot down Gascon's fleeing shuttle. However, Gregor survived the explosion, albeit with several intense head injuries, eventually making his way back to the Republic and his comrades, and is promoted to the rank of Clone Commander.

In 19 BBY, the Clone Wars came to an end with the reorganization of the Galactic Republic into the Galactic Empire. Gregor, however, did not carry out Order 66. Concurrently, the new government intended to phase out the clones, establishing a new army composed of recruits. Within Project War-Mantle, a secret base was established on the Outer Rim planet Daro, designated for the training of the new "TK troopers". Gregor became an instructor at a Daro facility where the next generation of Imperial troops was being trained. Fifty clone commandos, including Gregor, were deployed to the base as trainers. However, Gregor quickly realized that he did not want to be a part of the new Empire. He escaped the base, but was hunted. He managed to plant a rescue beacon before being recaptured and imprisoned. The beacon sent a distress signal to Captain Rex, who had also deserted from the military when he declined to obey Order 66. Unable to go himself, Rex asked the Bad Batch, a group of fellow deserters, to carry out the rescue.

Gregor was in his cell on Cellblock 25 when he demanded that the trooper on guard duty be useful and bring him some food. The trooper retorted that he was a traitor, and Gregor snapped back that it was "Captain Traitor" as the trooper walked away, before muttering that the recruit was an "Insubordinate pleb." Soon after that, the guards were neutralized by Hunter, Echo, and Tech as the Bad Batch approached Gregor's cell to set him free. Echo asked Gregor if he was CC-5576, and Gregor said it depended on who was asking. Tech said that Rex had sent them, and Gregor stood up and told them his name, saying they had to move out. As Hunter, Echo, Tech, and Gregor were making a swift escape from the base, Gregor took a hard shot to the chest by Scorch but survived and was evacuated from Daro at the cost of Hunter's capture and was left with information broker Ciddarin Scaleback on Ord Mantell. At some point his behavioral modification biochip was removed.

Gregor would join Rex's Clone Underground. He was part of the team who attempted to rescue a trio of clone prisoners from an Imperial Gozanti-class cruiser. Gregor piloted the ship while Echo, Fireball, and Nemec boarded the cruiser using a leech vessel. Gregor then docked the gunship onto the underside of the Imperial cruiser. Some TK troopers gathered at the round docking clamp airlock, and Gregor opened the hatch and threw in a stun grenade from below. After rescuing the clone prisoners, a Star Destroyer dropped out of hyperspace. A squad of V-wing starfighters pursued them, but the clones jumped to hyperspace and escaped.

Later, Gregor had a rendezvous scheduled with Echo, a fellow member of the Underground. He was picked up in the Remora and brought back to Teth, where the Underground's main base of operations was. However, their base had been infiltrated, and Gregor watched Echo fly towards a rendezvous and rescue Rex, Howzer, and the Bad Batch.

In the years following the Galactic Empire's creation, Gregor resided with Captain Rex and Commander Wolffe, both of whom had also removed their chips, within a modified AT-TE on the planet Seelos. Regrettably, due to the two traumatic brain injuries he had experienced, he suffered from episodes of mild insanity.

Four years prior to the Battle of Yavin, the crew of the Ghost approached the clones, seeking intelligence on abandoned military installations 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 explained that they were sent by Ahsoka Tano, Rex welcomed them as friends. Later on, Gregor encouraged the Lasat 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 too 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 discovered that one of the clones, Wolffe, had contacted the Empire. While Gregor and Rex had quickly trusted 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 Kanan 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 on their auxiliary ship Phantom to rendezvous with the Ghost in space. Shortly later, a force of three AT-AT walkers led by the Imperial Security Bureau Agent Kallus, a perennial foe of the crew of the Ghost. 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 and 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 continued to reside in the repurposed AT-AT walker, now christened Joopa Base. Gregor and Wolffe's modifications included a landing platform on top of their walker. Prior to the Liberation of Lothal, Hera, accompanied by Rex and former ISB Agent Alexsandr Kallus, journeyed to Seelos to persuade Gregor and Wolffe to assist Ezra in liberating 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 slim 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 group to defeat Governor Arihnda Pryce's forces at the Lothal cliff dwelling.

Following the capture of Governor Pryce, Gregor, Rex, and Wolffe participated 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 alongside him, saying that he was grateful to have died fighting for something that he chose to believe in before passing away. Rex stayed by his side until the end before returning to the fight. The rebels went on to liberate Lothal from Imperial rule at the end after the purrgil attached themselves to Thrawn's Star Destroyers and dragged them into hyperspace.

As a clone commando, Gregor possessed combat training and expertise in operating a blaster. Despite enduring a brief period of amnesia, Gregor displayed unwavering loyalty to the Galactic Republic, willingly risking his life for its cause. Having removed his control chip, Gregor remained unaffected by the transmission of Order 66. Due to the brain damage he sustained during the Clone Wars, Gregor experienced occasional episodes of insanity during the Age of the Empire. By the time he had defected from the Empire, his voice had gained a distinct rasp. When recruited by the Empire in training new recruits, Gregor was loyal to the Empire until he realized their ways was not what he signed up for and decided to defect from the Empire. Even when he was deemed a traitor by the Empire, Gregor openly remarked how proud he was for choosing to defect from the Empire.

Unlike Wolffe, Gregor, along with Rex, did not exhibit hostility towards Kanan Jarrus and his rebel cell, the Spectres. He befriended Ezra Bridger and particularly Garazeb Orrelios, 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, and they were willing to fight to the death in order to protect their new-found rebel friends from Imperial forces led by Agent Kallus. Gregor, Rex and Wolffe soon came to respect Kanan and Ezra after the rebels came to their aid and drove off Kallus' forces.

While Gregor thought that Ezra's plan to liberate Lothal had a slim chance of success, his loyalty to Rex and Ezra led him to volunteer for the mission. Gregor was a competent fighter and soldier who was able to fight as part of a team. Before he died during the liberation of Lothal, Gregor stated to Rex that it was an honor to fight with him, and for what they chose to believe in.

Gregor was a human male who stood 1.83 meters tall, or 6 feet. He had black hair, brown eyes, and tan skin.

As a clone commando, Gregor was skilled in both armed and unarmed combat and had knowledge of military tactics. He also demonstrated his skills in restaurant sanitation while working as a dishwasher at Borkus's diner.

While in service to the Grand Army of the Republic, Gregor wore Katarn-class Commando Armor with yellow markings and a grayish camouflage printing. He kept a tally of defeated droids on his helmet. His weapon of choice was the DC-17m Interchangeable Weapon System.

Gregor's initial appearance was in the Star Wars: The Clone Wars television show, specifically the "Missing in Action" episode from its fifth season. A promotional clip showcasing Gregor was subsequently presented at Celebration VI. Dee Bradley Baker provides his voice. The fifth season's trailer includes Aurebesh notes on Gregor's profile, which indicate he was MIA during the Sarrish battle.

In that episode, after R2-D2 scanned Gregor's ID, a hologram displayed his military records in Aurebesh. Besides indicating his MIA status from the Sarrish battle, the record also showed "SGT 1st Class," "212 Attack Battalion," and "Foxtrot Group," along with Gregor's measurements for height and weight. The SGT 1st Class title contradicts Colonel Gascon's statement that Gregor was a captain, even though Gascon based his statement on the hologram information.

The design of Gregor's helmet markings took inspiration from the hash marks that Boston Bruins goalie Gerry Cheevers used to draw on his mask, representing stitches he would have received without the protection.

Baker would later return to voice Gregor in the second season of Star Wars Rebels, the Disney XD animated series, specifically in "The Lost Commanders" and "Relics of the Old Republic." These episodes were first shown on October 8, 2015 at the New York Comic Con in 2015. He was mistakenly called a Clone Commander in the former episode. Three years after that, Baker once again voiced Gregor in the final Rebels episodes, "A Fool's Hope" and "Family Reunion – and Farewell," which debuted on March 5, 2018 on Disney XD.

Michael Moreci wanted Gregor to be a character in the Star Wars Adventures: The Clone Wars – Battle Tales comic book series during its development, but this was not permitted.
