Who Would Win in a Brawl?!

Joker would destroy Lex.

Intellect stands no chance against unpredictable, boundless insanity. JOKER curbstomps and laughs at his funeral where he kills everyone attending!

Luthor would destroy Joker. His intelligence is on par with Dr. Doom and the like. Joker would amuse Lex until he got tired of him and killed him.

Highly unlikely. My first comment was partly ironic because I don’t think Luthor would stand no chance against the Joker, but the Joker is the uncrowned King of Crime, and despite his madness he’s extraordinarily intelligent, I think he’d have a good chance defeating Luthor.

this is very situational.  Does Luthor have access to his battle suit? if so he would win.  If dropped in a room together with no weapons, it’s tough to say, Joker isn’t particular a capable fighter (usually), but sometimes has poison skin.  This is very tough to say.

The Joker would win.  Why?  Because the Joker is much better at cheating.

Joker would win He nearly baffled Batman at times and Batman could match luthors intellegence or better. But in the end joker would win because Luthor is obsessed with Superman
