Hot take;
It’s incredibly human to want to make giant crossover events. The Infinity War, the Argonauts, the Wacky Races, etc.
But actually it isn’t. Herakles/X-Men/Scooby Doo/Judge Dredd/etc are way awesomer largely off on their own doing Herakles/X-Men/Scooby Doo/Judge Dredd stuff with *maybe* also Atalanta/Inhumans/Predators/etc.
Make too much of a big hero rumble and it’s like having too much enchilada sauce on your fried kimchi and potato perogies with extra baba ganouj and cheese.
