Argyus

"Sometimes being a good soldier means doing what you think is right."

- Argyus

Argyus was a captain in the Senate Commandos, an elite branch of the Senate Guard, during the Clone Wars. He later betrayed the Republic for a reward promised by Count Dooku to free Viceroy Nute Gunray (http://starwars.wikia.com/wiki/Nute_Gunray). He was later killed by Ventress during the escape from the Republic ship.
