Rotskull is one of a duo, the principle rulers of the Horde of the Warmakers, a large gang that dominates the Deadlands, along with Slathazar. He is a cruel ruler, one who rules through fear. While many fear him, he is not exactly great at getting people to follow him, and he needed someone to back him up in order for him to have a real organization.
His fighting style is one of unrestrained savagery. He wields a two handed hax and a hook on a chain.
