I remember them in the film -- it was one of the design changes that most stuck with me when I first saw the movie next to the skullcap removal -- but in the movie they were longer along the forearm, less squaty.
If I could swing the cash, I'd love to have three of these guys -- a gang of 3 aliens in different prowl positions would look wicked.
And YES, Facebox, I think in the movie the bone things on the forearms were more like your 5" figures.
Wasn't there some debate about "warriors" and "drones" or something? Like the HT figure is more like a 'drone' in the Queen's nest at the end? Maybe we can settle this debate by calling this HT version a 'drone'? Or warrior, if I have it backwards.
