About the Pokédex and Rotom Phone

Any Pokémon that you find or catch during your adventure will have its information registered in the Pokédex. The Pokédex in these titles will actually be part of your Rotom Phone! Your Rotom Phone is also home to Rotom, a Pokémon that can enter into various electric appliances. And your Rotom Phone can do a lot more than serve as a Pokédex!
