Darth Smiley

"The Death Star… always brings a smile to my face. Vader...
Sith freak? Terrorizes? Wait 'till they get a load of me!"

Sand

"Aren't…aren't you coming with us, Lord Vader, to retrieve the Death Star plans?"
"What? You expect me to do down to a planet of sand? SAND???
It's coarse and rough and irritating and it gets everywhere!" 

IG-Something

"Shh! Bossk, it's me. IG-11! I'm covering for IG-88. He went on a drunken oil and battery spree last night and needs time to recover. Just act natural and no one will ever know."

Juiced Up

"So you wanted a rematch, Bane? No back breakers for 
me, now. I'm all juiced up and ready for you this time!"

Super-Dickery

"I…I didn't mean to gloat over having Christmas with my folks and make Batman cry. I guess I really am guilty of super-dickery now and then."
