Karkull quotes from Superman: The Animated Series

Karkull

You're strong for a mortal, but a mortal is all you are!

Karkull

I don't remember inviting you. Kill him.

Karkull

You continue to surprise me, but as I said, you don't have the tools to defeat me.

But I do!

Karkull

Fate... I thought our dealings had come to an end long ago.

No such luck, I'm afraid.

Karkull

What magic do you have that's powerful enough to defeat me in my own lair? [Fate reveals the Artifact] The Artifact of Lorta! I destroyed it!

What has been made can never be unmade.
