I like the idea of different versions of the same hero teaming up and comparing and contrasting their differences. The differences in their worlds and how they handle their threats. There's fun potential for storytelling there.
Yes, excellent example. The Spiderverse changed from being a gaggle of counterparts thrown together by chance and the villain's scheme, into the Counsel of Ricks. Instead of letting the different worlds breathe and bounce off each other, they were consumed into an unholy orobourus amalgamation.

Something like the Spiderman crossover but done well?
