Sean "Dark Smoke Puncher" McNinja is Doc's brother. He is an enormous poser, but he has some pretty slick ninja moves, and is undoubtedly a tech genius. He is capable of creating machines so advanced that they appear to mimic magic, hack high security computer systems and take control of machines. He built a horrifying robotic bear.
He is secretly a huge geek, as revealed when trying to call Gordito on using a phrase from 'Dark Tower', only for Gordito to realise that Dark Smoke Puncher would have had to read the book to know that.
