Darth Sidious

— The Force is with us, Master Sidious.
— Welcome home, Lord Tyranus. You have done well.
— I have good news for you, my lord. The war has begun.

— I'm looking forward to completing your training. In time, you will call me master.
— You're gravely mistaken. You won't convert me, as you did my father.
— Oh, no, my young Jedi. You will find that it is you who are mistaken... about a great many things.

— I hear a new apprentice you have, Emperor. Or should I call you Darth Sidious?
— Master Yoda. You survived.
— Surprised?
— Your arrogance blinds you, Master Yoda. Now you will experience the full power of the dark side.

— Master Windu. I take it General Grievous has been destroyed then. I must say you're here sooner than expected.
— In the name of the galactic Senate of the Republic... You’re under arrest, chancellor.
— Are you trending me, master jedi?
— Your fate will be decided by The Senate.
— I am The Senate!
— Not yet.
— It’s treason, then.
