9. Luke Skywalker
The hero of the New Republic, Luke Skywalker destroyed the first Death Star, founded Rogue Squadron, redeemed Darth Vader, distracted the Emperor from the space battle at hand, founded the Jedi Academy, and rebuilt the Jedi Order among countless other achievements. He became arguably the most famous person in the Galaxy and the Grand Master of the New Jedi Order all before he was forty years old and has already become one of the most legendary Jedi in the history of the galaxy. While he is the main character of the Original series, I don't think Luke is anybody's favorite character. He was always a little bit whiny, although by Return of the Jedi he is much better in that regard, and lacks the innate sense of cool that Han Solo and others possess. Still, he is simultaneously the best pilot and most powerful Jedi in the galaxy and he singlehandedly rebuilds the Jedi Order, fulfilling the potential that was present in Anakin Skywalker and being the central character in the entire original series so I can't very well put him much lower than this.
