These are the brand new evolutions you can get from your first gen Pokémon

Don't neglect catching more of the first generation Pokémon

Gen 2 Pokémon (from Pokémon Gold and Silver) arehere, adding 80 new Pokémon to the 151 original creatures in Pokémon Go. 

The best thing about this new update is many of your current Pokémon are able to evolve into all-new, unreleased forms, some even requiring special items that you can gain from Pokéstops. Here are all of them and how to get their new evolutions.  

Poliwhirl evolves into Politoed

The latest update will introduce more split evolution Pokémon like Eevee - Pokémon that can evolve into a more than one form. The tadpole Polliwhirl is one of them. Currently it only evolves into the tough Poliwrath at 100 candies. The new update gives Poliwhirl the option to become Politoed with 100 candies and the King's Rock special item. 

Eevee evolves into Umbreon or Espeon

Speaking of Eevee, this split evolution Pokémon gains an additional two forms when the update arrives - the Dark type Umbreon and Psychic type Espeon. We had a nickname trick to get Eevee to evolve into Jolteon (Sparky), Flareon (Pyro) and Vaporeon (Rainer). For Umbreon, give it the name Tamao, and for Espeon, key in Sakura. Like before, this only works the first time. 

Slowpoke evolves into Slowking

Another Pokémon that gained a new evolution is Slowpoke. Originally it could only evolve into Slowbro, one of the better Gym defenders in Pokémon Go. The new update should give Slowpoke the option to evolve into Slowking at 50 candies and a King's Rock special item. Slowking is what happens when a Shellder bites a Slowpoke’s head instead of its tail, turning it into a genius and giving it more Psychic strength.
