People say the Joker is Batmanās nemesis, and theyāre wrong. Joker doesnāt matter to Batman, heās just another two-bit villain. But Batman is the Jokerās nemesis. Because the Joker needs everyone to think heās funny, and Batman is a man with no sense of humour. Batman will never laugh and Joker will never stop trying to get a laugh from him. Batman is a great character to add to any Joker story.
But Joker is way more interesting in stories where he sucks. Harley Quinn is great because Joker is just another rapey man (who looks like Elon Musk) and he only matters because the patriarchy (and Harley) lets him matter. And Joker in Batman Beyond is hilarious, because Terry as Batman does have a sense of humour, and he knows Joker isnāt funny.
The chronic sleep deprivation certainly doesnāt help either.
