These are the 80 new Pokémon in 'Pokémon GO'

"Pokémon Go" just got a lot bigger this week, by about 80 Pokémon or so!

That's huge — like, Snorlax-huge — considering that the game started with only 142 of the original 151 Pokémon, the so-called "Gen 1" Pokémon. But in reality, there are hundreds of Pokémon, and the folks behind "Pokémon Go" are finally dipping back into the Pokédex for some new faces.

A new update is now live that finally allows you to catch the much-requested "Johto" region Pokémon from "Pokémon Silver & Gold" (aka "Gen 2" Pokémon). Of note: there are 100 Pokémon listed below, but some of these 100 aren't likely to appear in "Pokémon Go" (like all the Legendary Pokémon, for instance).

So, who are these mysterious new Pokémon? Let's find out, care of the official Pokédex (#152 to 251!):

152. Chikorita

"It uses the leaf on its head to determine the temperature and humidity. It loves to sunbathe."

153. Bayleef

"Bayleef’s neck is ringed by curled-up leaves. Inside each tubular leaf is a small shoot of a tree. The fragrance of this shoot makes people peppy."

153. Meganium

"The fragrance of Meganium’s flower soothes and calms emotions. In battle, this Pokémon gives off more of its becalming scent to blunt the foe’s fighting spirit."
