Grand Trials

After defeating all the Island Trials on a given Island, you must first defeat that Island's Grand Trial before moving on to the next Island full of Island Trials. Each Grand Trial is nothing more than a Battle, but with the Kahuna of each given Island. They are among the best trainers in all of Alola.
