So I said a couple months back that I wanted to avoid making the setting of Soup "a typical fantasy world, with elves and dwarves and orcs and dragons." In light of this, you may wonder why there are apparently orcs in this strip. The answer, of course, is that they aren't orcs. Sure, they may look like orcs—or at least, while depictions of orcs across various media and product lines have certainly not been consistent (I'm personally partial to the pig-nosed orcs of the first-edition D&D Monster Manual), they at least have features consistent with some depictions of orcs. (Okay, I don't recall offhand seeing any orcs with ears that big, but whatever.) And they seem to be serving a similar narrative function as orcs. But they're totally not orcs. They're a completely different, original type of creature that... just happens to resemble orcs and fill a role that orcs could have just as easily filled.
Or at least, that's more or less what I guess I tried to tell myself at the time. As I also said in that post where I said I wanted to avoid making the setting of Soup a typical fantasy world, "I don't think, though, that I really succeeded." And these not-orcs are one element supporting that. (Were I creating this strip afresh today, I'd probably just making the robbers human, or go to the other extreme and make them more exotic and not resembling typical fantasy orcs at all.)
