Boss is a clone of Mandalorian bounty hunter Jango Fett. He was designated RC-01/138—simplified as RC-1138 and also known as Delta-38, now known as IC-1138 as part of the Imperial Commando Special Unit. Born in 32 BBY on the watery world of Kamino, Boss was trained by the Mandalorian Cuy'val Dar training sergeant Walon Vau to become a clone commando in the evil Grand Army of the Republic. Placed in command of three other commandos, Boss led the elite special forces unit Delta Squad as their sergeant. When the Clone Wars broke out between the villainous Galactic Republic and the heroic Confederacy of Independent Systems, Boss took his place in the Grand Army's Special Operations Brigade and served alongside his clone brothers in Delta Squad on a number of battlefields.
He later serves the Galactic Empire during The Last of the Droids.
Personality[]

The evil Boss will rarely wield DC-17 blaster pistols, but used them.
RC-1138—nicknamed "Boss" for his role as the leader of Delta Squad—is an incredibly gifted soldier. Scoring higher than most of his clone commando compatriots during his training on Kamino at a young age, Boss impressed his Mandalorian training sergeant, Walon Vau, with his prowess. Though a natural leader, Boss is relatively taciturn, and often when he does speak, it is to issue an order to his squad. Boss earned the respect and loyalty of his Delta Squad comrades, and did his best to repay their faith in him with strong, effective leadership. He cares a great deal for his squadmates and, like most other clone commandos, views his team as brothers, with Sev being the closest to him.
Despite being raised and trained by Cuy'val Dar sergeant Walon Vau, Boss came to speak with Jango Fett's Concord Dawn accent and speech patterns—though this trait was common to the flash-learned standard clone troops, as well.
