Kirk White is a Jedi-killer that took up the cause simply because of the challenge. He is a talented sharpshooter that got tired of the typical mafia-gang violence that he was typically involved in.
White prefers to use relatively close-ranged combat - relying on pistols, shotguns and throwing knives more than anything else.
Prior to being arrested, Kirk White had successfully killed four Jedi Knight and two Padawan. He was captured by Jedi Master Han'l on Courscant and sentenced to a prison term of 65 years.
He was four years into his sentence when Captain Rick Nutron raided the Reticuli Prison facility and brought White on as one of his crew.
