Strangely enough, as the lucky owner/commissioner, that's exactly how I plan to use them in future scenarios - the mercenary bodyguard of the Kharzi of Kalabar:
In 'Sharp Practice' terms, they'll be aggressive natives with big choppers, with the added twist that they can never be broken and routed through accumulated Shock (though fisticuffs modifiers due to Shock will still apply) - they will fight to the death or until the Shock renders them unable to fight through the deduction of dice.
