User blog:Rmkane/Welcome to the Johto Region!

Starting this week, trainers be able to encounter 80 additional Pokémon from the Johto region from the Gold and Silver versions of the original handheld series.

Additional Pokémon
Pokémon like Chikorita, Cyndaquil, and Totodile will begin to appear, as well as gender-specific variations.

Evolutions
Some Pokémon from the Kanto region will soon be able to evolve—into Pokémon from the Johto region. Also, trainers should be on the lookout for Evolution Items at PokéStops which will assist them in evolving some Pokémon.

Encounters
Pokémon encounters in the wild will be changing as well. A new carousel will be available on the screen during an encounter which will allow trainers to quickly choose between Berries and Poké Balls.

Berries
Two new berries will start to become available at PokéStops. These include Nanab Berries, which slows a Pokémon's movement and Pinap Berries, which doubles the amount of Candy recieved if the next catch attempt succeeds.

Avatars and Wardrobe
In addition to backpack, hat, pants, shirt, and shoes customization; trainers will be able to further customize their belt, glasses, gloves, necklace, and socks.
