Evolved forms discovered in the Sinnoh region emerge in Pokémon GO!!
Did you know that some Pokémon originally discovered in the Sinnoh region evolve from Pokémon previously discovered in other regions? Starting today, you’ll be able to use a Sinnoh Stone to evolve Lickitung into Lickilicky, Tangela into Tangrowth, and more!
Plus, more Pokémon originally discovered in the Sinnoh region, such as Cranidos and Shieldon, will appear in the wild for the first time! You may also see more Pokémon originally discovered in the Sinnoh region appearing in Eggs.
There are also some big changes coming! You may notice that Pokémon that appear in Raid Battles are more powerful and sturdy when you challenge them. Plus, some moves that certain Pokémon know may be stronger or weaker when used in battle. Finally, certain Pokémon may be able to learn new moves via TM that will help them perform in battle, such as Machamp now being able to know the Rock-type move Rock Slide!
