Pokémon that were originally discovered in the Sinnoh region have recently begun showing up in Pokémon GO, and you can prepare yourself for the arrival of more during this special Hatchathon event. From November 14, 2018, at 1:00 p.m. PST to November 27, 2018, at 1:00 p.m. PST, some Pokémon with evolved forms originally discovered in the Sinnoh region—such as Rhyhorn, Porygon, and Magby—will be present in 2 km Eggs. There will be other Pokémon showing up in these 2 km Eggs as well, and for the first time, you may even hatch a Shiny Elekid, which evolves into Shiny Electabuzz and ultimately Shiny Electivire. Electivire, Rhyperior, Togekiss, Mismagius, Magmortar, Honckrow, Weavile, Dusknoir, Gliscor, Porygon-Z and Roserade have also made their Pokémon GO debuts. To obtain these Pokémon, you must evolve their previous forms by using 100 Candies and a Sinnoh Stone.
