This is the Head Alien’s first appearance.  He’s wearing a towel tied around his neck.  I can’t remember exactly what my original plans were, but I think he might have been an ascended normal alien at the time, having climbed his way up the ranks into an ultimate authority position he created.  I ditched all that later, deeming Head Alien always having been the Head Alien.  Consider his usual attire in the laundry or something.
