Nien Nunb is by far a more bizarre choice for a hero. He's also at the center of the 'who shot first debate.' In that context, it makes perfect sense for him to be included in an expansion that features Jabba's palace. Greedo, of course, is the infamous bounty hunter that confronts Han Solo in the Mos Eisley cantina in the first Star Wars film, hoping to claim the bounty put on Solo's head by Jabba.
