Evolution

**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, usually 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 to be evolved. There are some other Pokémon that require Evolution Items, special actions, Lure Modules, or actions performed as Buddy Pokémon.

### 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 its family, a second form costs **50** Candies to evolve from a first one.
	+ When Pokémon have three stages of evolution in its 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).
	+ 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 and Meltan need **400** Candies each to evolve into Gyarados, Wailord, Altaria, Volcarona, Noivern, Bewear, Golisopod and Melmetal respectively.
	+ 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 requires special **Evolution Items** in addition to Candies 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. It is always just one evolution item required to perform singular evolution.

### Buddy

These Pokémon that need certain **distance walked as Buddy Pokémon** in addition to Candies to be evolved.

 Pawmo  Pawmot | 25 km

There are also other evolution requirements to perform with Buddy Pokémon rather than walking distance.

### Time-based evolutions

Several Pokémon can only evolve during a certain time of day.

### Lure Modules

Other than the ordinary Lure Modules, other advanced versions require certain Pokémon to evolve when Trainer is within the range of the PokéStop under effect.

### Trade evolution

Since January 10th, 2020, certain Pokémon result in no Candy cost to evolve if they were previously traded. 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, upgrading a traded Machop to Machoke requires standard 25 Candies, but upgrading 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**). It is basically a group of Pokémon that are related with each other as one of such Pokémon evolve into or from another.

Pokémon evolution families can range between a 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. It is a temporary form change requiring Mega Energy. Pokémon are more powerful when Mega-Evolved.

## Trivia

* On the official support page for *Pokémon GO*, **Deepsea Scale** and **Deepsea Tooth** used to be mentioned.
	+ 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 is finally decided to be random.
* 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.
* 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 player has 23 Pidgey Candies and 2 Pidgey (which need 12 Candies to be evolved) they can evolve both of them, as the first one gives back 1 Candy and then the player still has 12 remaining. After evolving both Pidgey, there will still be 1 Candy remaining.
* Pokémon can be evolved at any health, even when fainted. After evolving, the new Pokémon would be at full health.
