Evolution is a game mechanic that allows Trainer to make Pokémon stronger and more advanced by feeding it with certain amounts of Candy. Evolved Pokémon generally has higher CP and HP, making them a more valuable for battles.

Evolving Pokémon

To evolve Pokémon, player needs to:

1. select a Pokémon to evolve from their Pokémon collection page
2. in Pokémon's summary page tap on the Evolve button.

Evolution costs

Every Pokémon that can evolve requires certain amounts of Candy in order to be evolved. There are Pokémon that require additional costs, such as Evolution Items, being in range of specific Lure Modules, performing actions as Buddy Pokémon, or other special criteria.

Candy

There are several patterns for Candy costs regarding the number of members of each Pokémon family.

• The most common patterns for evolution families:
  • When Pokémon have only two stages of evolution in their family, a second form costs 50 Candies to evolve from a first one.
  • When Pokémon have three stages of evolution in their family, a second form costs 25 Candies to evolve from a first one, and a third form costs 100 Candies to evolve from second one.
• Patterns for evolution families which Baby Pokémon were added to:
  • When Pokémon has Baby Pokémon introduced that makes its one-stage Pokémon family a two-stage one. A second form costs 50 Candies to evolve from a first one (Baby Pokémon).
    • There are multiple exceptions to this: Tyrogue, Smoochum, and Wynaut only cost 25 Candies to evolve.
  • When Pokémon has Baby Pokémon introduced that makes its two-stage Pokémon family a three-stage one. A second form costs 25 Candies to evolve from a first one (Baby Pokémon) and third form costs 50 Candies to evolve from a second one.
    • Only exception here is Marill family, as the costs of evolution into Azumarill from Marill and Marill from Azurill are 25 Candies each.
• Patterns for evolution families which trade evolutions were added:
  • When Pokémon is part of two-stage evolution family, a second form costs 200 Candies to evolve from an untraded first one .
  • When Pokémon is part of three-stage evolution family, a second form costs 50 Candies to evolve from a first one regardless of if it has been traded, and a third form costs 200 Candies to evolve from a second one that has never previously been traded.
    • Three-stage evolution families with trade evolutions that existed in game prior to the introduction of trade evolutions (Machop, Abra, Geodude, and Gastly families) maintain their previous Candy evolution costs: a second form still only costs 25 Candies to evolve from a first one regardless of it has been traded, and a third form still only costs 100 Candies to evolve from second one that has never previously been traded.
• Patterns for evolution families of the most common Pokémon:
  • When Pokémon is part of two-stage evolution family, a second form costs 25 Candies to evolve from a first one.
    • It applies to common Pokémon such as Rattata and Sentret and Pokémon that have branched evolution families such as Eevee and Tyrogue.
  • When Pokémon is part of three-stage evolution family, a second form costs 12 Candies to evolve from a first one, and a third form costs 50 Candies to evolve from a second one.
    • It applies to six Pokémon families: Weedle, Caterpie, Pidgey, Wurmple, Whismur and Pidove.
• Patterns for special evolution family:
  • Being a part of two stage Pokémon family, Magikarp, Wailmer, Swablu, Larvesta, Noibat, Stufful, Wimpod, Meltan, Toxel, Snom and Dipplin need 400 Candies each to evolve into Gyarados, Wailord, Altaria, Volcarona, Noivern, Bewear, Golisopod, Melmetal, Toxtricity, Frosmoth and Hydrapple respectively.
    • Toxel is the only Baby Pokémon that costs 400 Candies to evolve.
  • Being a part of two stage Pokémon family, Hisuian Sneasel, Snorunt and Feebas require 100 Candies to evolve into Sneasler, Glalie/Froslass and Milotic respectively. Some of them have additional requirements stated below.

Evolution Items

There are several Pokémon that require special Evolution Items in addition to Candies in order to evolve. There are currently eight Evolution Items: Sun Stone, King's Rock, Metal Coat, Dragon Scale, Up-Grade, Sinnoh Stone, Unova Stone and Gimmighoul Coins.

Trade evolution

Since January 10^th, 2020, certain Pokémon result in no Candy cost to evolve if they were previously traded.^[1] They are:

• Kadabra Alakazam †
• Machoke Machamp †
• Graveler Golem † (including Alolan form)
• Haunter Gengar †
• Boldore Gigalith †
• Gurdurr Conkeldurr †
• Karrablast Escavalier
• Shelmet Accelgor
• Phantump Trevenant
• Pumpkaboo Gourgeist

The dagger (†) denotes that these Pokémon are part of three-stage evolution forms, where the trade evolution benefit applied only for their second to third from. However, trading the first form applies to the benefit for their next evolution; for example, evolving a traded Machop to Machoke requires the standard amount of 25 Candy, but evolving further to Machamp will require no Candy.

Special actions

Evolving Inkay Malamar requires the mobile device to be turned upside down.

Pokémon families

Main article: List of Pokémon families

Each Pokémon is a member of a Pokémon family (also known as evolutionary line). Pokémon families a group of Pokémon that are related with each other, such as Pokémon that evolve into or from one another.

Pokémon evolution families can range between single to three-stage evolutions, but there can also be more than three members within a family, as some of Pokémon families might be branched.

Mega Evolution

Main article: Mega Evolution

Mega Evolution was announced and released in 2020.^[2] It is a temporary form change requiring Mega Energy. Pokémon are more powerful when Mega-Evolved. Mega Evolution provides other bonuses to gameplay. A special version of Mega Evolution called Primal Reversion exists for Kyogre and Groudon.

Trivia

• Unlike the main series games, Pokémon evolved in Pokémon GO do not have their currently learnt attacks persist through evolution. Evolving a Pokémon will cause its attacks to be rerolled using the new evolution's standard attack pool.
• On the official support page for Pokémon GO, Deepsea Scale and Deepsea Tooth used to be mentioned.^[3]
  • In the main series games, these items required to evolve Clamperl into either Huntail or Gorebyss respectively.
  • This concept was scrapped. The evolution of Clamperl was implemented to be a random choice between the two evolved forms.
• It was also stated there that Feebas would be required to be walked a minimum of 20 km as Buddy Pokémon, before it had been released to the gameplay.^[3]
• Searching the phrase "evolve" in Pokémon collection search return the list of all Pokémon with enough amount of Candies to be evolved.
• Every Pokémon gives back 1 of its Candy type when evolved. So for example, if a Trainer has 23 Pidgey Candies and 2 Pidgey (which need 12 Candies to be evolved) both can evolved, as the first one gives back 1 Candy and then the Trainer will still have 12 Candy remaining. After evolving both Pidgey, there will still be 1 Candy remaining.
• Pokémon can be evolved regardless of their current HP, even when they are fainted. After evolving, the Pokémon will be at full HP.
