The Butcher is a human soldier of Mandalorian origin who still keeps in touch with his warrior ways. He reaps and plunders ships who approach his territory for parts, equipment and, most importantly, slaves. He is a complete psychopath who brainwashes all his slaves to believe they are not people, they are meat. In his words, there are three kinds of meat: The fighting meat, the pleasure meat and the working meat. He trades slaves with the Empire, who, in turn, give him freedom and cover to do as he pleases and never be punished for it, or even be found.  He is an experienced fighter, a veteran commander and he keeps his ship (a massive, customized for battle, imperial cargo-transporter) in a very tight shift. A single slave has managed to escape his grasp, and that was Sienn T'arconna, his personal twi'lek sex slave.

The Butcher is the main villain.

He is a gruff sounding middle-aged man, whose every action and word sound brutal and rough. He is very smart, however, and his brawn should not be taken as a lack of brain. As a proud mandalorian, however, he would never run from a battle, which could cost him his life. His voice should be heavily distorted, because he uses a mandalorian hunting helmet all of the time. The Stranger's voice in Tales From the Borderlands would be a very solid base to work with.
