Leia Organa

"I don't know who you are or where you came from, but from now on you'll do as I tell you, okay?"

- Princess Leia to Han Solo

Princess Leia Organa of Alderaan (born Leia Amidala Skywalker; later Leia Organa Solo; and commonly referred to as simply Princess Leia) is a fictional character in the Star Wars universe.

She is portrayed by actress Carrie Fisher in Star Wars Episode IV: A New Hope, Star Wars Episode V: The Empire Strikes Back, Star Wars Episode VI: Return of the Jedi, The Star Wars Holiday Special and the upcoming Star Wars Episode VII: The Force Awakens. Aiden Barton appeared as an infant Leia in Star Wars Episode III: Revenge of the Sith. Ann Sachs provided the voice of Leia in the 1980s radio dramatizations of the original Star Wars trilogy and Lisa Fuson (Star Wars: Shadows of the Empire, Star Wars: Masters of Teräs Käsi, Star Wars: Rebellion, Star Wars: Galac).

Plot
Leia is one of the main protagonists of the original Star Wars trilogy. In Return of the Jedi, it is revealed that she is the twin sister of Luke Skywalker, and thus the daughter of Darth Vader/Anakin Skywalker. In the Star Wars prequel films, her mother is identified as Padme Amidala.

Her adoptive father is Bail Organa, who is depicted as the head of Alderaan's royal family and a supporting character in the prequels; in later Star Wars literature she marries Han Solo, her romantic interest in the original films and had three children with him, whose names were Jacen, Jaina, and Anakin.

Trivia

 * She takes after her father, though she isn't happy about it. She is way more proactive and stubborn than her brother, and she isn't nearly as forgiving of Vader's sins. The Noghri call her "Lady Vader" for a reason.
