(Source used: http://www.starwars.com/databank)

Protagonists: Luke Skywalker,  Princess Leia Organa

Luke Skywalker was a Tatooine farm boy who rose from humble beginnings to become one of the greatest Jedi the galaxy has ever known. Along with his friends Princess Leia and Han Solo, Luke battled the evil Empire, discovered the truth of his parentage, and ended the tyranny of the Sith. 

Princess Leia Organa was one of the Rebel Alliance’s greatest leaders, fearless on the battlefield and dedicated to ending the tyranny of the Empire. Daughter of Padmé Amidala and Anakin Skywalker, sister of Luke Skywalker, and with a soft spot for scoundrels, Leia ranks among the galaxy’s great heroes. But life under the New Republic has not been easy for Leia.


Anti Hero

Smuggler. Scoundrel. Hero. Han Solo, captain of the Millennium Falcon, was one of the great leaders of the Rebel Alliance. He and his co-pilot Chewbacca came to believe in the cause of galactic freedom, joining Luke Skywalker and Princess Leia Organa in the fight against the Empire.

Antagonist: Darth Vader

Once a heroic Jedi Knight, Darth Vader was seduced by the dark side of the Force, became a Sith Lord, and led the Empire’s eradication of the Jedi Order. He remained in service of the Emperor -- the evil Darth Sidious -- for decades, enforcing his Master’s will and seeking to crush the fledgling Rebel Alliance. 

Flat Character:

C-3PO is a droid programmed for etiquette and protocol, built by the heroic Jedi Anakin Skywalker, and a constant companion to astromech R2-D2.  He is the stereotype of a bureaucrat, we know that he will always be worried and anxious, he is predictable. In some ways he is almost a dull parental figure to create contrast with the other crew members and make them seem more dynamic.


Round Characters:

Luke, Leia, Hans and Darth are all round characters because there characters all face internal conflicts, they sometimes act in ways that surprise us and we are given a good deal of information on their back stories, fears, desires, motivations etc
