Following Palkia's arrival in Raid Battles, a few new Gen 4 Pokemon have now begun appearing in Pokemon Go. Niantic has introduced another handful of monsters originally from the Sinnoh region--the setting of Pokemon Diamond and Pearl--to the mobile game, including a couple of new evolved forms and baby Pokemon.
If you have a Sinnoh Stone, you're now able to evolve Lickitung, Tangela, Aipom, and Yanma into their respective evolutions: Lickilicky, Tangrowth, Ambipom, and Yanmega. Additionally, male Kirlia can be evolved into the Psychic/Fighting Pokemon Gallade, while female Snorunt can be evolved into Froslass.
A handful of new monsters can also be found in the wild. You'll now have a chance of encountering Combee, Glameow, and the fossil Pokemon Shieldon and Cranidos out in the field. Happiny, Mime Jr., and Bonsly--the baby forms of Chansey, Mr. Mime, and Sudowoodo, respectively--also now have a chance of hatching from certain Eggs.
Along with the new Pokemon, Niantic has made some notable changes to Raid Battles. As the developer detailed on the official Pokemon Go website, Raid bosses will now have more HP "to offset some of the damage increases made to the attacks of other Pokémon in the last year." Niantic has also made balance changes for various moves in Trainer Battles, and certain Pokemon are now capable of learning new attacks.
The aforementioned Legendary Pokemon Palkia will appear in Raid Battles until February 28. Meanwhile, the next Pokemon Go Community Day is scheduled to take place on Saturday, February 16. The featured Pokemon this month will be Swinub.
