In the contention for Nob is the newly modelled 'Ead Boy, some say that he milks squigs to oil his head piece, other that you can find him howling at the far end of the skid on a full moon. All we know is, he's called the 'Ead Boy.
I'm quite likely to be using this boy as the leader, and downgrading Sneakin Bossstompa to a boy, the head piece carries the tribal theme quite well and the overly huge choppa/slugga scream "I'm da 'ardest"
