Darth Sidious: "Come to the dark side, Kongou and abandon that evil admiral. I'll make you Vader's replacement and you can have a tea party with my senators and generals other than serving my Galatic Emprire if you want.
Kongou: "Really?"
Darth Sidious: "That's right. Come with me, and I'll christen you Darth Kongou if you accept me as your master."
