Sort of a random pondering.
The art of Hobgoblins in Runner's Companion are sort of inconsistent - not a criticism, mind you, just observing. Just as the various depictions of any of the Metahumans/Metavariants vary from artist to artist, and in their level of consistency with the text descriptions, the Hobgoblin art is highly varied (well, considering there's only like three pics, total, in all the books, of a Hobgoblin).
So if I mark the handful of pictures in RC up to artistic license, my interpretation is that instead of typical Ork tusks, Hobgoblins (having the Fangs Quality) have a more predatory tooth configuration - more like a wolf, big cat, or maybe even Vampire than, say a tusked creature like a boar. My reasoning is that creatures with tusks use them very differently than creatures with fangs...as Hobgoblins can actually use a bite attack, like a predatory critter, and not a tusky critter (boars, elephants, etc, use their tusks to gore, not chomp), they don't actually have the signature tusks of a normal Ork.
And yes. I am well aware I'm totally over-thinking this.
What else is new?
