The Rotom
Pokedex was first introduce in
Pokemon Sun & Moon, where Rotom would inhabit your Pokedex and help your trainer along the way with certain tips and advice. In
Pokemon Sword & Shield, Rotom once again inhabits a device that belongs to your trainer, this time a phone. The
Rotom Phone works similarly to the Rotom Pokedex, since the Rotom Phone will still act as your Pokedex and will keep track of all the Pokemon you
Encounter during your journey. However, it won't constantly need attention and it won't give as many tips as the Rotom Pokedex once did.
On top of acting as your
Pokedex, the
Rotom Phone will also have an additional feature of a becoming a Bike. You will earn this access after defeating
Team Yell on
Route 5, and the Bike helps players get to places much faster than on foot. Later in the game, your bike will even become equipped to traverse over water! With the Rotom Phone, you no longer need a Pokemon to travel across the waters of a region!
