METAL HEAD is a rocker from the 80's. He turned to a life of crime because he was a burnout back in high school. He may look menacing, but he is about as harmful as the guitar player from Spinal Tap.
Q- "Would you say that criminal behavior is a result of socio-enviromental conditions or individual mental health?"
A- "Well...uh...I uh...well...ROCK N' ROLL!!"
