Zarkon is Dying (1984)

Jack Angel: King Zarkon

Quotes 

• Prince Lotor : You must rest.

  King Zarkon : [Groans in pain]  I can't conquer the universe *that* way.

• [last lines] 

  King Zarkon : Ahh, wonderful, just what I needed, a magic potion. I feel strong, ready to take the throne again. And by the way, Lotor, if your medicine had happened to be poison - which of course it wasn't - it wouldn't work. Long ago Haggar cast a spell on me to protect me from all such dastardly attempts on my life! Ha ha ha ha! So you see, my ambitious son, you'll just have to be patient. Zarkon will be on the throne for a long, long time!
