The Clown Prince of Crime
Super Freak
But it's not about being bigger, they can still do small stuff. Plus the Joker has rarely been a doomsday device kind of villain, he's better off in smaller, more personal stories. So he remains unaffected imo.
I don't know, there are a bunch meta humans and this Batman has no problem killing thugs, so how is The Joker still alive? It just seems that after watching Batman go at it with Sups or Doomsday...maybe even Darkseid. The Joker is just some dude with bad tattoos Maybe if they make a smaller solo Batman film he can still be effective as a villain.
