I am the hope of the universe. I am the answer to all living things that cry out for peace. I am protector of the innocent. I am the light in the darkness. I am truth. Ally to good! Nightmare to you!

"In brightest day, in blackest night,
No evil shall escape my sight.
Let those who worship evil's might
Beware my power--Green Lantern's light!"

Obi-Wan: You were the chosen one! It was said that you would destroy the Sith, not join them. You were to bring balance to the force, not leave it in darkness.
You were my brother, Anakin. I loved you

Obi-Wan Kenobi: You have allowed this dark lord to twist your mind, until now, until now you've become the very thing you swore to destroy.

Anakin Skywalker: Don't lecture me, Obi-Wan! I see through the lies of the Jedi. I do not fear the dark side as you do. I have brought peace, freedom, justice, and security to my new Empire.

Darth Vader: Don't be too proud of this technological terror you've constructed. The ability to destroy a planet is insignificant next to the power of the Force.

Admiral Motti: Don't try to frighten us with your sorcerer's ways, Lord Vader. Your sad devotion to that ancient Jedi religion has not helped you conjure up the stolen data tapes, or given you enough clairvoyance to find the rebels' hidden fortress...
[Vader makes a pinching motion and Motti starts choking]

Darth Vader: I find your lack of faith disturbing.

The Lord of the Rings: The Return of the King
Hold your ground, hold your ground! Sons of Gondor, of Rohan, my brothers! I see in your eyes the same fear that would take the heart of me. A day may come when the courage of men fails, when we forsake our friends and break all bonds of fellowship, but it is not this day. An hour of wolves and shattered shields, when the age of men comes crashing down! But it is not this day! This day we fight! By all that you hold dear on this good Earth, I bid you stand, Men of the West!
