Ask any Star Wars fan, who's the ultimate hero and you're bound to get a variety of answers. Here's proof that the most consistent hero--always saving the day--is none other than R2-D2.
Take a look and see for yourself. Any time a character was written into a wall, inexplicably, R2-D2 had the power, knowledge and omniscience to get the job done! You can't say that about ANY OTHER CHARACTER!
