Imprisoned in Stryker, a heavily guarded & secured prison in Metropolis for whatever crime he did… was Lex Luthor in a cell… standing up & humming to himself… potentially plotting… 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. In his cell, suddenly multiple green holographic screens (maybe 7) popped up around him while he watched them intently… showcasing various things like different heroes (Supes one of them ofc), etc.

(How did he even build all that here…)

Lex (to himself):

(’We’re all lucky I prepared my own contingency plans in case I ever got imprisoned at Stryker. I’m slightly annoyed they thought this could ever hold me.’)

(He’s right ofc. He has immense resources… and his intelligence is even scarier. This was actually just Stage 1 of his plan for him. Whatever plan that is)

(He already knew you were going to come for him. As if you could ever catch him off guard. He then turns to face you with a slightly smug glare, screens all disappeared before you came)

Lex:

“Right on cue. The actions of a neanderthal. I assure you, even in here, you are no match for me.”
