Mike's left arm is completely bionic, after it was brutally chopped off when he was a Teenager. And sometimes, he likes to put on a light show to freak people out! Hehe, he plays it all out, pretending its shocking him. But it really isn't, hehe.

Nice concept art Kael threw together for me, thanks Bud!
