Android 18 and Super Android 17 in “Unfinished Business”

I can't even look at you anymore. You sicken me. You're half of what you were before.

Heh. How do you figure that one, 18? I'm twice as strong now.

Strength is one thing, 17. But character is another. The 17 I knew wasn't a cold blooded killer. At one time you were programmed to destroy Goku, but you never took pleasure in killing innocent people! You even managed to overcome the programming. You were so strong and independent that you refused to be controlled. But now look at you. If you wanna kill Goku and me, go right ahead. But you know full well that I have a bomb in my chest. So if you take me down, you're going with me!
