CT-8801 was a clone trooper of the Galactic Republic who fought as part of the Grand Army of the Republic during the Clone Wars. Between 19 BBY and 18 BBY, after the Republic reorganized into the Galactic Empire at the war's end, CT-8801 continued his service in the newly formed Stormtrooper Corps, functioning as a stormtrooper for the Imperial Army. At some point after the Republic's reorganization, the trooper was stationed with a company of other clones under Clone Captain Wilco on the occupied planet Serenno.
Alongside the rest of the company, CT-8801 was tasked with securing and retrieving the war chest of Dooku, the deceased Count of Serenno. While patrolling near the final transport to be loaded, the trooper encountered the rogue clone commandos of Clone Force 99, who had come to Serenno in hopes of taking some of the war chest. Incapacitated upon detecting the commandos, CT-8801's sudden neglect to report to Wilco eventually caused alarm among the Imperials and started a search for him.
CT-8801 was born on the planet Kamino as a genetic clone of the human bounty hunter and clone template Jango Fett and enlisted into service for the Galactic Republic and its army. While fighting in the Clone Wars against the Confederacy of Independent Systems, in 19 BBY, CT-8801 and the rest of the Republic's clone troopers received orders from Supreme Chancellor Sheev Palpatine to execute the members of the Jedi Order, who were branded state enemies, in accordance with Order 66 and dictated by his behavioral modification biochip. After Order 66, the war ended, and Chancellor Palpatine reorganized the Republic into the Galactic Empire.
Following the Republic's transformation, CT-8801 and the clones of the former Republic Army continued their service as stormtroopers in the newly formed Imperial Army. Between 19 BBY and 18 BBY, CT-8801 and an over forty-man-strong company of clone troopers led by Clone Captain Wilco were sent to the planet Serenno, the homeworld of deceased Separatist leader Count Dooku, which had been occupied and ravaged by the Empire. Their mission was to infiltrate Dooku's former palace of Castle Serenno to retrieve his war chest, a massive stockpile of valuables that had been plundered from the worlds controlled and besieged by the Separatists during the war, and send it off-world aboard three class four container transports. However, in the same year, as the war chest had become sought-after by the criminal underworld with Dooku's passing, a squad of rogue clone commandos known as Clone Force 99 had traveled to Serenno in hopes of retrieving enough treasure to secure their freedom from both the Empire and mercenary work.
Arriving on the planetary surface at Castle Serenno, the squad remained undetected by the Imperial forces and boarded the third transport before it took off. While inside the container transport, CT-8801 was simultaneously conducting a patrol of the area, during which he heard clattering from inside the transport by Clone Force 99 members Tech, Echo, Wrecker, and Omega. Alerted and attempting to investigate, Wrecker promptly stunned and incapacitated the trooper, eventually causing alarm among the Imperials upon his failure to report back to the company of his patrol. Responding to his sudden disappearance, Captain Wilco ordered several troopers to investigate and the third transport to later depart after discovering the rogue clones. Not long after the cargo ship had taken off, CT-8801 soon woke up but was immediately stunned once more before the commandos launched themselves away aboard the containers, leaving the trooper unconscious aboard the freighter.
At birth, like the other clone troopers, CT-8801 was implanted by the Kaminoan scientists with a behavioral modification biochip to ensure that the trooper would not resist certain orders. He wore a set white Phase II clone trooper armor equipped with an integrated comlink and was armed with a DC-15A blaster carbine and a single N-20 Baradium-core thermal detonator on the back of his utility belt.
CT-8801 was introduced in "Spoils of War," the premier episode for the second season of the Star Wars: The Bad Batch animated series, which first aired on Disney+ on January 4, 2023. Similarly to the other clone troopers in the series, CT-8801 was voiced by Dee Bradley Baker.
