Vargus served as a commander of clone troopers throughout the Clone Wars. As the head of Excelsior Company, this specific clone unit successfully destroyed droid armies on Ando Prime, an ice planet; these forces were led by Confederate General Grievous.
Vargus had a shaved head and a notable scar that ran across his nose. His armor featured orange designations and a grey command sash that went across his chest. Known to be intense and strict, Vargus often critiqued new troopers, but was generally a just leader who freely gave praise when merited. He also demonstrated intelligence and practicality in his strategic approaches. Vargus also possessed a cynical attitude, holding a low opinion of his role as a clone, viewing himself and his fellow clones as disposable soldiers created to perform the unpleasant tasks of the Galactic Republic. When questioned about the consequences of his and his men's potential deaths, Vargus succinctly stated, "They'll just make more of us."
