"Let me at 'em!" was Hardcase's typical reaction when presented with enemy forces, no matter how overwhelming the odds. Legend has it that his growth chamber sprung a leak during his formation on Kamino, resulting in his characteristic, somewhat aberrant, but nonetheless useful hyperactivity. When the blaster bolts fly, Hardcase loses all sense of self-preservation and returns fire with zeal, determined to wipe out the enemy with repeated sweeps of his rotary laser cannon.
Hardcase served the 501st Legion under the command of Clone Captain Rex. He was part of Rex's squad of clone troopers dispatched to Saleucami to track down a fugitive General Grievous.
Jesse and Hardcase share a devotion to duty, but while Jesse's service is rooted in a patriotic love of the Republic, Hardcase is more focused on the adrenaline rush of the battlefield.
The squad medic Kix has patched up Hardcase on more than one occasion, as the eager trooper often rushes into combat situations without thinking of his own safety.
Hardcase can truly appreciate firepower and battlefield prowess, so he relishes fighting side-by-side with a special forces veteran like ARC Trooper Fives.
