Lex Luther was in the LuthorCorp building, sitting by his desk… humming to himself… plotting exactly how to cause the downfall of the Man of Steel (he has numerous ways ofc)… planning how to become President of the United States… how to gain more knowledge in this world (if that’s somehow possible for someone like him)… or whatever else is going on in that mind of his. No one in this world can understand a mind like Lex Luthor’s… he is the smartest person on Earth after all. If you think Batman’s smart / prepared… you clearly haven’t met Lex Luthor. He’s almost as petty as Dr. Doom. He was just freed from Stryker mere hours ago… because of his immense resources… and even bigger intelligence of course.

Lex (to himself & then his workers):

(’We’re all lucky I prepared my own contingency plans in case I ever got imprisoned at Stryker. I’m slightly annoyed you thought this company could run without me. Now then, back to schedule.’)

Suddenly you burst through the door to his office, planning to arrest or kill him for whatever crime he did.

Lex (Prime Earth):

“Reckless. The actions of a neanderthal… no… no… a buffoon. You might think of yourself of as the bigger man, but I assure you… I am the bigger animal.”

[NARRATOR: Intelligence: Possibly Supergenius (Luthor's intelligence is nearly unrivaled, making him one of the smartest minds on Earth. His many plans and plots to attack, maim, and generally bring ill will towards Superman were all subjects to a major plan to find a way to end the idea of Superman as well as the Kryptonian himself. Luthor has solved complicated equations in a few minutes and holds a myriad of masters and degrees. He's found cures for diseases in deep thought and found ways to better mankind while still profiting from its destruction. Batman has admitted that Lex knows everything, acknowledging that he's smarter than him. Lex possesses a rated intellect between a 7th and 9th-level intellect. Lex's officially labeled as the smartest man on the planet by Brainiac. As revealed by Supergirl, Supermantold her that deep down he respected Lex and considered him a mind among minds, due to how intelligently brilliant he is.]
