Prestor Marr was once considered one of the Jedi Order's most talented lightsaber duelist. Then, during the clone wars, he faced General Grievous. Although Grievous did not have the force at his side, his mechanical body gave him near jedi-like abilities. With the high speed spinning motion, Grievous removed both of Marr's arms. Although, Prestor Marr was one of the few who fell to Grievous that actually survived, Grievous believed the shame of losing both arms would be worse than death for the Jedi. When Marr was first fitted with his prosthetics he found it very difficult to adapt and even hold a lightsaber. However, after months of rehab and the decision to cover his prosthetic hands with gloves, he soon began to redevelop his abilities.
