Pokémon Sun and Moon: Acerola

Technically speaking, Sun and Moon don’t have Pokémon gyms, so they don’t really have gym leaders. But they do have the Island Challenges across the islands of Alola, and they’re basically the same thing, just with a different cultural context specific to the region. As such, we can count Acerola among the other gym leaders we’ve discussed. By Gen VII, the ghost-type has become a pretty diverse group of Pokémon, after originally only including the Gengar family. Acerola’s team is full of ghost Pokémon, but each of them includes a secondary typing: Sableye has dark type, Dhelmise grass type, and Palossand gets ground type. There’s always something extra to be worried about with her team, and they’re among some of the highest-level foes you’ll face in Sun and Moon’s late game. Even if you’ve got a reliable dark-type Pokémon to Crunch through her party of poltergeists, she will likely cycle through something that will have your number.
