Pokémon Go has just dropped the fourth generation of Pokémon. If you’re reading this and you’re a Pokémon Go aficionado… why aren’t you out there catching Pokémon already?
Included in this first drop are Gen 4 starters Turtwig, Chimchar and Piplup, plus common species such as Bidoof and Starly.
At present, Pokémon from previous generations with new Gen 4 evolutions (such as Magmar, Electabuzz and Tangela) can not be evolved.
