Here are the Pokémon you should stockpile in 'Pokémon Go' before the 80 new ones are released into the wild

Espeon pokemonCartoon Network / The Pokemon CompanyEevee will be able to evolve into Espeon and Umbreon when Pokémon Go’s second generation of creatures is released.

More than 80 new Pokémon are coming to “Pokémon Go” this weekend as part of a massive, second-generation update.
Certain Pokémon that are currently in the game, like Eevee and Seadra, will be able evolve into unreleased second-gen Pokémon from the original game’s Johto region.

“Pokémon Go” creator Niantic Labs has revealed that you’ll need special evolution items from Pokéstops to evolve some creatures from the game’s first generation into their second-generation counterparts. But you’ll also want to stockpile candies now from existing Pokémon so you can power them up once they’re evolved.

We’ve used data complied by the Pokémon Go experts from The Silph Road on Reddit, Bulbapedia, and official creature descriptions from the master Pokédex to put together the following list:

Eevee evolves into Espeon and Umbreon.

The Pokemon Company

Eevee already has three powerful evolutions in 'Pokémon Go': Vaporeon, Flareon, and Jolteon.

When the second generation of creatures drops, Eevee will also be able to evolve into Espeon and Umbreon.

Here are their official descriptions:

'Espeon is extremely loyal to any Trainer it considers to be worthy. It is said that this Pokémon developed its precognitive powers to protect its Trainer from harm.'

'Umbreon evolved as a result of exposure to the moon's waves. It hides silently in darkness and waits for its foes to make a move. The rings on its body glow when it leaps to attack.'

If the same naming trick for Eevee's current evolutions lets you choose which second gen creatures to evolve into, you'll want to nickname your Eevee its respective trainer name from the original Pokémon show: 'Sakura' or 'Sayo' for Espeon, and 'Gary Oak' for Umbreon.

Slowpoke evolves into Slowking.

The Pokemon Company

Slowpoke will either evolve into Slowbro or Slowking once the second generation of creatures is released. You'll likely need a special evolution item to evolve into Slowking.

'Slowking undertakes research every day in an effort to solve the mysteries of the world. However, this Pokémon apparently forgets everything it has learned if the Shellder on its head comes off.'

Seadra evolves into Kingdra.

The Pokemon Company

Seadra's second-generation counterpart is Kingdra, a powerful water/dragon Pokémon.

'Kingdra sleeps on the seafloor where it is otherwise devoid of life. When a storm arrives, the Pokémon is said to awaken and wander about in search of prey.'

Zubat evolves into Crobat.

The Pokemon Company

'Crobat sneaks up on its intended prey using wings that barely make a sound. This Pokémon rests by hanging on a tree branch with its rear legs that serve as wings.'

Chansey evolves into Blissey.

The Pokemon Company

Given how rare Chansey is in 'Pokémon Go,' it will be difficult to accrue what will likely be 100 candies needed to evolve into the powerful Blissey. (Let's hope that's not the case.)

'Blissey senses sadness with its fluffy coat of fur. If it does so, this Pokémon will rush over to a sad person, no matter how far away, to share a Lucky Egg that brings a smile to any face.'

Gloom evolves Bellossom.

The Pokemon Company

Gloom will be able to evolve into either Vileplume or the second-generation Bellossom.

'A Bellossom grows flowers more beautifully if it has evolved from a smelly Gloom -- the more stinky the better. At night, this Pokémon closes its petals and goes to sleep.'

Onix evolves into Steelix.

The Pokemon Company

Onix is relatively weak in the game now, but the rock creature may be redeemed once it evolves in Steelix from the game's second-generation list of creatures..

'Steelix lives even further underground than Onix. This Pokémon is known to dig toward the earth's core. There are records of this Pokémon reaching a depth of over six-tenths of a mile underground.'

Poliwhirl evolves into Politoed.

The Pokemon Company

Hang onto those Poliwag candies! Poliwhirl will be able to evolve into either Poliwrath or Politoed.

'The curled hair on Politoed's head is proof of its status as a king. It is said that the longer and more curled the hair, the more respect this Pokémon earns from its peers.'

Scyther evolves into Scizor.

The Pokemon Company

It will probably cost a special evolution item to evolve Scyther into a more powerful Scizor.

'Scizor has a body with the hardness of steel. It is not easily fazed by ordinary sorts of attacks. This Pokémon flaps its wings to regulate its body temperature.'

Porygon evolves into Porygon2.

The Pokemon Company

Porygon is already hard to find in 'Pokémon Go,' so hang onto as many candies as you can for when Porygon2 is unlocked. It will be a collector's item.

'Porygon2 was created by humans using the power of science. The man-made Pokémon has been endowed with artificial intelligence that enables it to learn new gestures and emotions on its own.'
