first things first. NOBODY said DC Villains wouldn't make it in Marvel.
Two. Everybody's bringing up all of these crime lords and kings and shyt and you're missing the point. YES, Joker is an A-List DC villain.
But he's a STREET LEVEL BATMAN VILLAIN. He would give Spiderman migraines, yes. Daredevil, possibly. BUT HE WOULD BE A STREET LEVEL VILLAIN.
And you gotta look at it like this: Damn near every superhero in Marvel operates in New York. Joker fukks with Batman's folks mainly IN GOTHAM.
He's not gonna be pulling that wild out shyt all over New York. He's prolly stay in Hell's Kitchen or some shyt. HE WOULDNT BE AN A-LIST VILLAIN.
He wouldn't know how to deal with a Wolverine, he wouldn't know how to deal with a Punisher.
And YES, The Hood through some wack ass writing, was giving The Avengers fits. But only because he organized every B and C lever crook into an army after Kingpin fell off. Villains in DC don't wanna deal with The Joker like that. lmao He's to craaaazyyy. And no, I don't see Joker going off on some epic quest for the Infinity Gems. I'm not going to try and figure out how The Hood was hunting the gems. I didn't read that shyt.
He wouldn't last as an Avengers villain. How long would that really last?
He wouldn't last as an X-Men villain, unless they gave him some insanity aura mutant power.
Who would that leave? The Prowler? Joker gonna set up shop in Houston and fukk with Scarlet Spider?
DC Villains in Marvel? YES. Hell, Pre-Reboot Rogues would wreck shop in Marvel.
Joker, by his very nature? Just because he gives Batman fits at the whim of writers?
no.
