Star Wars edge of the empire - The Wheel
He is more machine than man now.
Half his face scarred and cut. Crazy eyes and implants. His jaw replaced by durasteel. His one arm replaced by a Plasma Shell Assault Cannon. He strikes a intimidating figure and his subordinates (and some of his superiors) visible fear him.
A former storm Trooper Sgt after suffering horrific injuries he has now turned into a cyborg.
After to exchanges with the crew both endangered in his defeat and both involving explosives.
He is now after revenge more than anything else. He has connections to the people hunting Ferro and Xora.
Becoming a full cyborg is very expensive and hard for both body and mind. Not done well and carefully it is very dangerously.
