Goku and Nuova Shenron in “Unfinished Business”

(after Nuova goes into his ultimate form) Impressive. So this is your true form I take it?

Yes. You have drawn me out of my shell so to speak. What you see before you is my ultimate fighting form. And now that I've raised the stakes, it's your turn. It's time to ante up or fold.

Fold? No chance of that! I'll see you and I'll raise you! (Goku turns into Super Saiyan 4)

So, Super Saiyan 4, you've come out. Lets play.
