Pokémon Sun and Pokémon Moon take place in the Alola region, which centres around four tropical islands and one artificial island. Many Pokémon that have never been seen before inhabit the lush islands of the Alola region.  Professor Kukui is the Alola region’s Pokémon professor. Sporting a white lab coat, Professor Kukui has his own unique style. Lillie is a mysterious girl who assists the professor. This young girl is about the same age as the player’s character and is Professor Kukui’s assistant. Lillie will play an important role in the story of Pokémon Sun and Pokémon Moon. Hau is a Pokémon-loving young boy with a big appetite. He is the same age as the player’s character. Hau becomes one of the main character’s first friends. In Pokémon Sun and Pokémon Moon, Professor Kukui provides a special Pokédex known as the Rotom Pokédex. The Rotom Pokédex does much more than record Pokémon info - it has its own personality. Besides showing the player’s current location and their next destination, the Rotom Pokédex also provides advice on where to go next. Three new first-partner Pokémon will join Trainers on their adventures in the upcoming Pokémon Sun and Pokémon Moon games: Rowlet Litten Popplio The two legendary Pokémon that appear on the packaging of Pokémon Sun and Pokémon Moon play a crucial role in the story: Solgaleo Lunala
