Methods of Evolution
There are numerous methods of evolution which define how and when Pokémon evolve. Most Pokémon will evolve by leveling up while others evolve through specific means, such as being traded, achieving a certain amount of friendship or leveling at certain times, among others.
In the core series
In the core series games, Pokémon normally only evolve after one of three events:
Prior to Generation VIII, the above were the only triggers to evolve Pokémon. However, Pokémon Sword and Shield introduced four new triggers, each only used by a very select few Pokémon species:
- Spinning and striking a pose with the Pokémon in the party
- The Pokémon performing a specific action in battle
- Traveling through a specific location with the Pokémon in the party
- Observing a specific object in a specific location with the Pokémon in the party
When the appropriate trigger occurs, if the Pokémon meets the requirements to evolve, it will do so. However, if a Pokémon meets the trigger in battle, it will only evolve after the battle ends.
The Everstone prevents a Pokémon's evolution:
- In Generation II, a Pokémon holding an Everstone (including Kadabra) cannot evolve by any method.
- In Generation III, trade evolutions are affected by the held item loss glitch: if Kadabra, Machoke, Graveler, or Haunter is traded while holding any item (including an Everstone), that Pokémon will evolve and its held item will be permanently lost.
- From Generation IV onwards, the Everstone does not prevent a Pokémon evolving via Evolution stone. It also fails to prevent Kadabra from evolving.
- If either Karrablast or Shelmet holds an Everstone when traded for the other, neither can evolve.
Leveling up
Leveling up is the most common trigger for evolution. Evolution by level up can be triggered by gaining experience in battle or by using a Rare Candy; leveling up in Pokémon Day Care or Isle Evelup will not trigger evolution, although Pokémon leveled up in these ways can still evolve if leveled up by battle or a Rare Candy afterwards. All Pokémon that evolve by leveling up have at least one requirement that must be met when leveled up in order to evolve, the most common being that the Pokémon must be at least a specific level after leveling up. Other requirements include knowing a specific move, being in a specific location, or holding a specific item. A Pokémon that meets its level-up evolution requirements will always attempt to evolve when it is leveled up in battle or by using a Rare Candy, regardless of whether it had previously been prevented from evolving.
If a Pokémon levels up in battle, it will not evolve until the battle is over. A Pokémon can only evolve once after a battle or consuming a Rare Candy, even if it gained multiple levels. Even if a Pokémon is fainted at the end of the battle, if it leveled up when it met its evolution requirements during the battle, it will still evolve, but will not be revived from fainting. However, prior to Generation VI, the player's Pokémon would not evolve if player lost the battle, even if its evolution requirements were met.
Starting in Generation VIII, if a Rare Candy is used on a level 100 Pokémon that evolves by leveling up and currently meets its evolution requirements, it will evolve (without gaining a level).
In Pokémon Legends: Arceus, evolution can be performed at any time, so long as the conditions are met, instead of requiring a level up.
At or above a certain level
- Main article: List of Pokémon that evolve at or above a certain level
Most Pokémon evolve when they reach or surpass a certain level. Once such a Pokémon has reached the required level, unless there are other requirements for its evolution, it will attempt to evolve after every battle in which it levels up and every time it gains a level from a Rare Candy.

When friendship is high
Some Pokémon evolve when they are leveled up with a friendship of at least 220. Like friendship itself, this evolutionary requirement was introduced in Generation II. As long as the Pokémon has the required amount of friendship, unless there are other requirements for its evolution, it will attempt to evolve whenever it levels up by battle or Rare Candy.
Baby Pokémon often have this evolution requirement, but it is also an evolution requirement for other Pokémon, and not all baby Pokémon have this as an evolution requirement.

When the Pokémon knows a certain move
Some Pokémon evolve when they are leveled up and know a certain move or certain type of move. This evolutionary requirement was introduced in Generation IV.
If the Pokémon learns the required move by leveling up, that same level up can trigger the evolution. However, if a Pokémon learns a move by level up and overwrites the required move, such that it no longer knows the required move at the end of the battle (or after completing the level up in the case of a Rare Candy), it cannot evolve.
These moves are commonly available by leveling up, although some are only learned at level 1, so they normally must be taught by the Move Reminder.

In certain locations
Some Pokémon evolve when they are leveled up in certain locations. This evolutionary requirement was introduced in Generation IV.
There are four different types of location that can trigger location-based evolutions: Moss Rock, Ice Rock, special magnetic field, and Mount Lanakila. Mount Lanakila, which is only required for Crabrawler's evolution, is the only one which is a specific location rather than a type of location.
Pokémon HeartGold and SoulSilver lack the locations needed for location-based evolutions, making them impossible within those games. Starting in Generation VIII, although some games still feature location-based evolution and others do not, it is possible to instead use Evolution stones to evolve these Pokémon (except for Nosepass and Eevee's evolutions into Probopass and Glaceon respectively in Pokémon Brilliant Diamond and Shining Pearl).

Nosepass |

In a certain region
Some Pokémon evolve when they are leveled up in a specific region. This evolutionary requirement was introduced in Generation VII.
Pokémon that evolve this way may also need other conditions, such as requiring it to be a specific time of day. Some Pokémon evolve into different forms depending on what region they are in.

At certain times
Some Pokémon evolve when they are leveled up at a certain time of day. Like the time mechanic itself, this evolutionary requirement was introduced in Generation II.
The time of day is only ever one of several requirements, never the only one. Other requirements it is combined with include having high friendship or holding a specific held item.
Due to the lack of a time system in Pokémon FireRed and LeafGreen, Pokémon Colosseum, or XD, Pokémon whose evolution depends on the time cannot be evolved that way in these games. In Pokémon XD, evolutions that depend on the time of day in the core series games instead depend on the Sun Shard and Moon Shard.
In Pokémon Sword and Shield, time is pre-set outside the Wild Area before becoming Champion. This also influences evolution.

The specific times in each game that count as day and night for evolutions are detailed in the table below.

While holding an item
Some Pokémon evolve when they are leveled up while holding a specific Evolution item. If a Pokémon evolves this way, the item disappears upon completion of the evolution; the item is not consumed if the evolution is cancelled. This evolutionary requirement was introduced in Generation IV.
All Pokémon that evolve this way also require that they be leveled up at a specific time of day to be evolved.

If the Pokémon is a certain gender
The evolution of some Pokémon that evolve when they are leveled up is dependent on the Pokémon's gender. This evolutionary requirement was introduced in Generation IV.
Combee and Salandit can evolve only if they are female (males cannot evolve). Burmy evolves into either Mothim or Wormadam, depending on whether it is male or female, respectively.
Gender | ||
---|---|---|
Combee |
+ → Level 21+ if female |

In a certain game
The evolution of Rockruff and Cosmoem is dependent on the game they are leveled up in. This evolutionary requirement was introduced in Generation VII.
Cosmoem will evolve into either Solgaleo or Lunala depending on the game it is leveled up in. Rockruff will always evolve into Lycanroc, but, prior to Generation VIII, Lycanroc's form depends on the game Rockruff was evolved in, and Rockruff's evolution can only occur at certain times of day (Midday Form requires it be daytime while Midnight Form requires it be nighttime); furthermore, special Rockruff that have Own Tempo can only evolve into Dusk Form Lycanroc, which is not dependent on the game. Starting in Generation VIII, the form Lycanroc becomes is no longer version-exclusive.

This evolution method was introduced in Generation IX. Some Pokémon may evolve upon level up after using the Let's Go! feature to walk 1000 total steps.

Unique conditions
The following Pokémon evolve through a method that is isolated to their evolution line only.
- In Pokémon XD: Gale of Darkness only, Eevee evolves into Espeon or Umbreon when leveled up with a Sun Shard or Moon Shard, respectively, in the player's Bag. Only one of the two items can be obtained per game.
- Eevee evolves into Sylveon when leveled up while knowing a Fairy-type move and having at least two levels of affectionVI—VII or high friendshipVIII+.
- Mantyke evolves into Mantine when leveled up with a Remoraid in the player's party.
- Feebas evolves into Milotic when leveled up with its Beauty condition at 170 or above. Starting from Generation V, it also evolves into Milotic when traded while holding a Prism Scale.
- When Nincada evolves into Ninjask (which it does starting at level 20), if there is an empty slot in the party, a Shedinja will appear. From Generation IV onward, the player must also have a spare standard Poké Ball in their Bag.
- Pancham evolves into Pangoro starting at level 32 if there is a Dark-type Pokémon in the party.
- Inkay evolves into Malamar starting at level 30 when leveled up while the game system is held upside-down. On the Nintendo Switch, this can only be accomplished in handheld mode.
- Sliggoo evolves into Goodra starting at level 50 during rain (or fogVII-VIII) in the overworld. (Rain that is only present in battle will not trigger the evolution.)
- Finizen evolves into Palafin starting at level 38 when leveled up while connected with another player via the Union Circle.
- Primeape evolves into Annihilape when leveled up after using Rage Fist at least 20 times.
- Bisharp evolves into Kingambit when leveled up after defeating three Bisharp that hold a Leader's Crest.
- Gimmighoul evolves into Gholdengo when leveled up while the player has 999 Gimmighoul Coins in their Bag. This consumes the Gimmighoul Coins, and the evolution cannot be canceled.
Additional factors
Some Pokémon with branched evolutions can evolve into one of multiple different Pokémon or different forms of the same Pokémon depending on other factors, but still have the same evolution requirements for all of these possibilities.
- Burmy evolves starting at level 20, but its evolved form is determined by its gender and, if female, its cloak. As Burmy, its cloak changes according to the place where it last battled but has no effect on Burmy itself; once it evolves into Wormadam, its cloak no longer changes, and its types and the moves it can learn are dependent on its cloak.
- Tyrogue evolves starting at level 20, depending on its stats.
- Hitmonlee if Attack > Defense
- Hitmonchan if Attack < Defense
- Hitmontop if Attack = Defense
- Wurmple evolves into Silcoon or Cascoon starting at level 7, depending on its personality value. It is a hidden value determined when the Pokémon is encountered and cannot be seen or affected by the player.
- Dunsparce evolves into Dudunsparce when levelled up while knowing Hyper Drill. The form of Dudunsparce it evolves into depends on its encryption constant. Since this value cannot be influenced or seen by the player, what a given Dunsparce will evolve into is essentially random — with a 1/100 chance of evolving into Three-Segment Form Dudunsparce.
- Tandemaus evolves into Maushold starting at level 25, but if Tandemaus is not sent out in the battle it levels up in, the evolution animation will be skipped. The form of Maushold it evolves into depends on its encryption constant. Since this value cannot be influenced or seen by the player, what a given Tandemaus will evolve into is essentially random — with a 1/100 chance of evolving into Family of Three Maushold.
Using an item
Some Pokémon evolve when they are exposed to a specific item. The player can use one of these items on a compatible Pokémon at any time outside of battle, which consumes the item. From Generation IV onwards, evolution by exposure to an item cannot be prevented by holding an Everstone. Due to being able to evolve at any time, these Pokémon usually learn fewer or no moves by level up after evolving; however, in Generation VIII, even if they do not learn any additional moves by level-up, they normally can still be taught any move their pre-evolved form could learn by level up by the Move Reminder.
In Pokémon Legends: Arceus only, Pokémon that would normally evolve while holding a particular item (including by leveling up while holding a specific item) instead evolve when exposed to that item.

Evolution stone
- Main article: Evolution stone
- See also: Category:Pokémon that evolve by Evolution stone
The most common type of item that can trigger this kind of evolution is an Evolution stone (and was the only type that could, prior to Generation VIII). Despite its name, the Oval Stone is not an Evolution stone, because it triggers evolution as a held item rather than by being used directly.

If the Pokémon is a certain gender
While most Pokémon that evolve by Evolution stone have no additional requirements, some Pokémon that evolve this way can only evolve if they are a specific gender. This evolutionary requirement was introduced in Generation IV.
The only two evolutions with this requirement are Kirlia's evolution into Gallade (which requires that it be male) and Snorunt's evolution into Froslass (which requires that it be female). These two evolutions are the only evolutions to use the Dawn Stone.

In a certain region
While most Pokémon that evolve by Evolution stone have no additional requirements, some Pokémon can evolve into a different form when they use an Evolution stone in a specific region. This evolutionary requirement was introduced in Generation VII.
Special itemsThe following items are each only used by one Pokémon to evolve.
TradingSome Pokémon evolve when they are traded. The evolution starts immediately after the trade is completed, regardless of the method of trading used. However, sometimes there are additional conditions. In the anime, Pokémon that evolve by trade sometimes evolve after being temporarily in a different person's possession, like Misty's Politoed being with Nurse Joy at the Pokémon Center and Brock's Steelix when he lent Onix to his brother Forrest.
Trade holding a certain itemSome Pokémon evolve when traded while holding a specific Evolution item. If a Pokémon evolves this way, the item disappears upon completion of the evolution. This method of evolution was introduced in Generation II (the same generation that introduced held items in general). In Pokémon Legends: Arceus, Pokémon that evolve when traded while holding a specific item can be evolved without trading by using their evolution item from the player's satchel.
Trading for a certain PokémonSome Pokémon evolve when traded with a specific Pokémon. Only two Pokémon do this so far and evolve each other through this method. This method of evolution was introduced in Generation V. If either Pokémon holds an Everstone, neither can evolve.
Unique triggersGeneration VIII introduced several unique triggers for newly introduced Pokémon and regional forms. These triggers are all exclusive to a single Pokémon.
Can only evolve in other gamesMeltan, which first appeared in the core series games in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, cannot be evolved in the core series games. Instead, it can only be evolved in Pokémon GO, where it can be evolved by pressing the "Evolve" button on Meltan's profile screen and spending 400 Meltan Candy.
In spin-off games
Pokémon GO
In Pokémon GO, the only way to evolve Pokémon is to press the "Evolve" button on that Pokémon's profile page. All Pokémon require the player spend a specific amount of their own Candy to evolve them, but some have additional requirements. Some evolutions require an item in addition to the Candy cost. All evolutions that require an Evolution item other than an Evolution stone (except Feebas and Clamperl) or Sun Stone to evolve in the core series require an item to be spent in Pokémon GO. For evolutions introduced in Generation II, the item required is the same as in the core series. All cross-generational evolutions introduced in Generation IV, except location-based evolutions, require a Sinnoh Stone to evolve. All evolutions introduced in Generation V that require an Evolution stone in the core series (except a Sun Stone) require a Unova Stone in Pokémon GO; Generation V evolutions that require a Sun Stone in the core series also require it in Pokémon GO. From January 10, 2020 onward, certain Pokémon do not cost any Candy to evolve if they are traded. These Pokémon are Kadabra, Machoke, Graveler, Haunter, Boldore, Gurdurr, Karrablast, Shelmet, Pumpkaboo, and Phantump. Feebas, Bonsly, Mime Jr., Happiny and Woobat cannot be evolved until the player has walked with them as Buddy Pokémon for a sufficient distance (the specific distance varies between species). This requirement is noted under the "Evolve" button. For some species of Pokémon with branched evolutions, there are multiple "Evolve" buttons, allowing the player to choose which Pokémon to evolve into. The different buttons may have different requirements, such as one button requiring an item while another does not. Despite having branched evolutions, Eevee, Tyrogue, Wurmple, and Clamperl only have a single button. Some of them have no indication of which Pokémon it will evolve into in most cases.
Pokémon Pinball series
In Pokémon Pinball and Pokémon Pinball: Ruby & Sapphire, once the Evolution Mode or Evo Mode starts and the player chooses a Pokémon to evolve, then three instances of the same Evolution Item appear somewhere on the table, one at a time. The player is required to get the three repeated Evolution Items before the time runs up in order to evolve the chosen Pokémon. For instance, if the player attempts to evolve a Vulpix into Ninetales, they will be required to find three Fire Stones on the table. Most available Pokémon evolve by experience, which requires getting three "Ex" Evolution Items. If the Pokémon evolves by trade in the core series, then the player needs to get three Link Cable Evolution Items. In the TCG
In the Trading Card Game, there are no different methods needed to evolve a Pokémon, but instead, all Pokémon evolve simply by placing the next stage on top of a Pokémon in play that it evolves into. For instance, if the player has a Vulpix card in play, they may evolve it by placing a Ninetales card on top of it. Some cards reference methods of evolution found in the core series, such as the Moon Stone and the Dusk Stone. The evolution procedure from the real-life card game is used in Pokémon Trading Card Game, Pokémon Card GB2: Here Comes Team GR!, Pokémon Play It!, and Pokémon Play It! Version 2. Trivia
