The aloria region is home to a battle gimmick called “apex forms” to get an apex Pokemon you must have the “apex necklace” key item (above), defeat ten of any wild Pokémon and to finish it you need to go to the “apex researcher” in a town that is unlocked after beating the third gym then you can choose a Pokémon in your team able to turn into their apex forms and then you can call that form after your Pokémon attacked three times during battle. An example of apex forms is on noivern.
