Michael Myers is a toxic male

Can't recall if we've ever seen him eat or drink, let alone a reference to such ever made in the films, so I'm not even sure if he even pees or poops. But then again, perhaps it would grow back like a lizard's tail, what with his constitution.

And to OP, wile I normally think "toxic" is an overly dramatic term to describe someone, in this case, it's kind of letting the incarnation of evil off a little light.
