The Pokédex is a convenient tool that records information about the Pokémon you see and catch during your adventure. In Pokémon Sun and Pokémon Moon, your character receives a special Pokédex from Professor Kukui to support you in your travels. It's known as the Rotom Pokédex, and it's inhabited by Rotom, a Pokémon with the power to reside in various electronic appliances. It does much more than record Pokémon info—it sparkles with its own personality. The Rotom Pokédex shows your current location and your next destination, and it also gives you advice on where to go next, based on the conversations you have with others! It's likely to be of great help to you in many parts of your adventure.
