When viewers first saw the Star Wars: The Force Awakens trailer, they were introduced to this strange droid that sped through the desert. Skeptical fans lamented the "lame" CGI effect that this droid obviously was. Right?
Actually, no. As the world would discover, BB-8 was very real. An amazing piece of robotics, he was revealed to fans in Anaheim, posing with his co-stars.
Fans can even own their very own version of BB-8 in a smaller form.
