"I am your Father!"

"The Force is strong with this one."
[talking about Luke]

Darth Vader: "I've been waiting for you, Obi-Wan. We meet again, at last. The circle is now complete. When I left you, I was but the learner, now I am the master."
Obi-Wan Kenobi: "Only a master of evil, Darth."

Darth Vader: "Your powers are weak, old man."
Obi-Wan Kenobi: "You can't win, Darth. If you strike me down, I shall become more powerful than you could possibly imagine."

Darth Vader: "What is thy bidding, my master?"
Emperor: "There is a great disturbance in the Force."
Darth Vader: "I have felt it."
Emperor: "We have a new enemy, the young Rebel who destroyed the Death Star. I have no doubt this boy is the offspring of Anakin Skywalker."
Darth Vader: "How is that possible?"
Emperor: "Search your feelings, Lord Vader. You will know it to be true. He could destroy us."
Darth Vader: "He's just a boy. Obi-Wan can no longer help him."
Emperor: "The Force is strong with him. The son of Skywalker must not become a Jedi."
Darth Vader: "If he could be turned, he will become a powerful ally."
Emperor: "Yes. Yes. He would be a great asset. Can it be done?"
Darth Vader: "He will join us or die, my master."

Lando Calrissian: "Lord Vader, we only use this facility for carbon freezing. If you put him in there it might kill him."
Darth Vader: "I do not want the Emperor's prize damaged. We will test it on Captain Solo."

"The force is with you, young Skywalker, but you are not a Jedi yet."

Darth Vader: "You have learned much, young one."
Luke Skywalker: "You'll find I'm full of surprises."
