Justice League, Season Four

[After Brainiac reveals himself from within Lex Luthor]

Flash:
Dude. That is messed up.

Lex Luthor:
I don't understand what's happening!

Brainiac:
You are under my control. I have lain dormant within you for years, Lex Luthor, subtly influencing your actions until we arrived at this point. Do you not recall my kidnapping you in this very building?

[A flashback to the Superman:
TAS episode "Ghost in the Machine" is shown]

Lex Luthor:
Yes... You forced me to build you a new body.

Brainiac:
Kal-El destroyed that body, foiling my plans. In any event, I always have a backup plan. Consider: how could you have survived that point-blank blast from me, unless--

Lex Luthor:
Unless... It wasn't intended to kill me?

Brainiac:
The beam carried a nanotech payload that inserted a microscopic, holistic copy of my program inside your body. Since then I have steadily grown in strength, protecting this body until I could arrange my transfer into a more suitable one.

Lex Luthor:
You cured my cancer; gave me super-strength!

Brainiac:
Your animal-protein shell was insufficient for my needs. Improvements were required.

Flash:
Hate to interrupt this special live performance of "The Thing With Two Heads", but it's time to go to jail now.

Amanda Waller:
What he said. [shoots Brainiac/Luthor]
