I agree with Anakin being the most important character. He is essential to the story line. HE killed the Jedi, HE was Luke and Leia's father, He married Padme, HE was the chosen one, and HE became Darth Vader. Shmi is also important too. It was Shmi's death that nudged Anakin to the dark side. Now, bare with me, Shmi is important herself, she gave birth to Anakin, but she said there was no father. This implies that the force gave her the baby, right? So couldn't the force have given it to any other woman, making her important instead? I just wanted to point out that fact.
It's kinda of a debate....it's Anakin Skywalker and Luke Skywalker AND Shmi Skywalker. If Shmi hadn't given birth to Anakin there'd be no first movie. If Anakin hadn't existed there'd be no first, second, or third movie. And if Luke hadn't been born there'd be no fourth, fifth, or sixth movie.
It is defitnely Anakin Skywalker because it is his life story. The prequel trilogy starts with him as a child, and the original trilogy ends with him dying. Yes, there are many sub-main characters in Star Wars but Anakin is defitnely the one that is the most important. Technically, Darth Vader is Anakin Skywalker.
Anakin. Because if anakin never existed, there would be no chosen one. if he never existed, luke would have never existed. And if luke never existed, there would be no more jedis left (Since all the jedis died and he was the only one left)
Hold on one second there. I don't mean to disagree with you're comments about who's number one. But seriously, you should consider the fact that without Obi-1 Kenobi, there wouldn't be the last of the Jedi's. Obi-1 is also important, as well as Yoda is. Not to mention Luke and his friends.
I can't really answaer that, because let's say Qui-Gon Jinn got killed by Xanatos. Then he'd be replaced by someone else in the films. Same goes for everyone. Without Anakin, Luke, Shmi, Obi-Wan, Qui-Gonn, Yoda, Palpy, Leia, Han, Lando, Chewie, everyone would have a replacement.
Other than that, I'd say Anakin. Without him (no matter how sucky Christensen's acting was), we would have the Galaxy as we know it. As a replacement, Sidious might have turned someone else to his will. Someone less strong, someone not the chosen one. Without Anakin, we'd never have a succesful rebellion, because we wouldn't have Luke and Leia to keep the whole thing going. Bail Organa would have been killed, then we'd have Mon Mothma and Ackbar left. They'd be captured, and Ackbar would be executed and Mothma would be imprisoned.
Thus you can see a lot of side effects of no Anakin.
But then let's say we had no Qui-Gonn. Who'd bring Anakin to the Jedi? No one. Eventually he would grow up and join the Republican forces during the Clone Wars, then the Empire would take over, and Anakin would join the Rebellion. But he wouldn't meet Padme. No Luke or Leia? Goodbye Galaxy, hello Imperial Rule.
What if we had no Obi-Wan? No one to cripple Skywalker. Sidious would have an ultimately powerful apprentice, a Darth Vader who could even summon Force lightning! Then we'd have no one to bring Luke to the direction of the Force. Even if say Yoda found him, it'd be too late.
My best answers would be Anakin, Qui-Gonn, and Obi-Wan in that order.
I think it's Anakin/Vader. Because, c'mon, he's the Chosen One, and the only one alive ('cept Palpatine, but that old coot doesn't count. In fact, Star Wars would be *great* without his meddling) thorough all six movies. He's the one who made the decision to betray the Jedi, turn against them and slaughter them, and Vader is the one who almost single-handedly handed an entire Imperial Fleet, hunting Rebels for twenty-something years. Every single thing in all of the six movies seems to revolve around him, and him only. It just wouldn't be Star Wars without him!
Oh, and just as a reminder - Luke and Leia would never be born. Galaxy, you're officially doomed.
