The Butcher Demons are a type of demon. Many of them exist within the Burning Hells, and they were once under Diablo's command. The Butchers are stitched together from the parts of other demons to combine their strengths, then given life through magic. As such, Butcher Demons see all living and unliving things as mere parts. The Butchers that serve Duriel bolt plates of burning iron to their flesh.
