Max Battles are a new form of “raids” in Pokémon Go that work around the Dynamax feature, debuting on Sept. 10.

While not much is known about the Dynamax feature or Max Battles at the start of September, many details are expected to come out in the first couple of weeks of the month. Still, even without the specifics, we already know which Pokémon will debut and feature throughout September and when they end.
