Mic is odd. Unlike other Automates, he is extremely altruistic and only works as a mercenary to make real change in the world. And even then, he only takes on jobs that he feels are meaningful and oftentimes will only take what he needs to survive as payment.
Mic is also odd for another reason, he has second personality inside him; the Stranger. The Stranger seems only concerned in self preservation but has done unspeakable things to do so.
