He's one of the later range of Aly Morrison's C10 half-orcs. I prefer the earlier, solid-based ones, as they're nastier-looking. The later, slotta-based ones like this chap are more comic and loutish rather than grim and murderous like their predecessors. Still, the later range are nice, characterful miniatures all the same - perhaps more at home bullying hobbits in the Shire than hewing down Theodred at the Isen (change their livery and give them axes, and the earlier bunch would do that job nicely).
This fellow will probably see service in our D&D games as a brigand, an untrustworthy hired scout or even a PC.
