Greedo is the central character of the Star Wars mythology. Greedo was the catalyst that spurred Han Solo into action--had Greedo not fired first at Han, causing him to respond, Han would still be sitting thoughtfully in that cantina. Instead, Greedo's surprise attack on Han gave him the motivation he needed to get moving, ultimately finding himself responsible for saving the life of Princess Leia moments before her execution, and saving Luke moments before his destruction at the hands of Vader (which in turn allowed the destruction of the Death Star) and later on Hoth. Without Han's intervention, the Rebellion would have ended on Yavin, and the deaths of Luke and Leia would have prevented the ultimate victory over Palpatine and return of Anakin Skywalker and peace to the galaxy. All of this because Greedo shot first! It is so appropriate that this character be remembered in such a fine fashion by the folks at Sideshow!!
