One idea could be a story where the Peacock Miraculous has a unique malfunction that causes it to create unexpected akumas.

This could involve exploring the history of the Miraculous and its connection to this new threat.
One idea could be a crossover where the Miraculous heroes and Ben 10 team up to fight a common enemy.

And a third could be a story where Ben gets akumatized and the Miraculous heroes have to figure out how to save him without using brute force as his alien forms are very powerful.

One idea could be that during Halloween, the Miraculous holders have to deal with akumas that are inspired by classic horror movie monsters.
