Ghost was born in 32 BBY on the water planet of Kamino, cloned from the genetic template of the infamous bounty hunter Jango Fett. Ghost received basic training and eventually graduated. He differentiated his armor, marking it with blue markings, as well as growing a beard. He would also suffer a wound at some point, resulting in a scar over his right eye. Being one of the oldest clones existing, he began to grow weary of being designed for war, which resulted in him no longer being willing to sacrifice himself for the Republic.
Following the First Battle of Geonosis, Ghost aligned himself with Commander Griebs Kishpaugh, who was also prepared to depart from the Republic. The two contacted the Separatists and were told their price to escape was the planet of Oznek, which was a world that would allow the Separatists the ability to capture the sector. The two put together a mission and assembled a squad of troopers run by Sergeant Banks.
The unit was deployed in a Low Altitude Assault Transport/infantry but was shot down in the process. The intel that was given to the squad was that the area was uninhabited by droid forces, however, this was falsified by Ghost and Kishpaugh. After fighting off a unit of droids and losing a few brothers, the squad carried on to hold up at an abandoned hut. Crazy Legs, the ship's pilot, had been severely injured, so they left him to heal, while they continued the mission. However, a unit of droids would come after the squad, finding Crazy Legs first and killing him. While heading for the compound, the unit lost another member. Ghost, Banks, Cutter, Syke, and another squad member continued on to the compound. However, the squad was captured by locals. But due to a Separatist attack, the locals let them free and the squad assisted in taking the droids out.
Cutter and the other trooper remained behind to hold the droids back, while Ghost, Banks, and Syke carried on to the compound. While searching, Ghost shot Syke in the back, killing him, and attempted to kill Banks. However, due to Banks' ability to reflect shots off other surfaces, Banks managed to kill Ghost while he was choking him.
