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 maximum happiness, leveling at a certain hours, among others.
Triggers
As of Generation IV, Pokémon may only evolve (having met certain requirements) after one of three events:
- Leveling up
- Being exposed to an evolutionary stone - 24 Pokémon
- Being traded - 16 Pokémon
Of course, it is not sufficient that one of these events happens, but it is also necessary that all the required conditions are met. Therefore, when we are speaking about a method of evolution, we mean both the event and the conditions. Which one of the evolution-triggering events must happen to make certain Pokémon reach its next evolution stage and what conditions must be met is determined for each Pokémon individually.
Pokémon from branched evolution families may evolve into different forms depending on the event that caused evolution and other conditions.
Evolving by level
Most Pokémon are able to evolve by leveling up. A Rare Candy will also trigger evolution if all conditions are met. It should be noted that a Pokémon left in Daycare will not evolve--even if all conditions are met--until it's leveled up in battle or given a Rare Candy.
There are currently no Pokémon that require additional conditions to evolve by leveling.
Reaching a certain level
Amongst Pokémon that evolve by level, they will evolve as soon as certain level is reached by gaining enough experience after a battle. If a Pokémon is not able to evolve when it reaches the required level, it will try to evolve every time it levels up again. To avoid this, an Everstone given to the Pokémon will suppress evolution until it is removed.
Example: Ekans evolves into Arbok at level 22.
This method of evolution doesn't have special disadvantages in most cases. However, Meowth, for example, evolves into Persian at level 28, but learns Pay Day at level 32. In Generation IV, Persian cannot learn Pay Day by leveling up, this means that if a player wants to have a Persian with Pay Day, the player must not let Meowth evolve until it learns the move.
Furthermore, Pokémon cannot evolve if they are still in their base form until level 100, because they cannot level up any further.
Happiness
Some Pokémon evolve by leveling up if their hidden Happiness stat is 220 or above. It's more common with baby Pokémon such as Cleffa, but other evolved Pokémon like Chansey (which evolves further into Blissey) require it. This method of evolution was introduced in Generation II.
The following Pokémon evolve in this manner:
- Golbat → Crobat
- Chansey → Blissey
- Pichu → Pikachu
- Cleffa → Clefairy
- Igglybuff → Jigglypuff
- Togepi → Togetic
- Munchlax → Snorlax
- Buneary → Lopunny
Less common conditions
Knowing a certain move
Some Pokémon evolve when they reach a level while they know a particular move, which is available by leveling up. If in any case they are made to forget the moves, the Pokémon must relearn it in order to evolve with the help of move relearner. This method of evolution was introduced in Generation IV.
Being in a certain area
Since the introduction of Generation IV games, the following Pokémon only evolve by leveling up in the specified area:
- At Mt. Coronet
- In Eterna Forest
- On Route 217
Holding a certain item
Some Pokémon evolve when they level up if they are holding a certain item. In this case, the item disappears after the Pokémon evolves.
- Happiny (holding Oval Stone) → Chansey
- Gligar (holding Razor Fang) → Gliscor
- Sneasel (holding Razor Claw) → Weavile
For more information on how Onix evolves into Steelix, see below.
By time and happiness
The following Pokémon evolve by leveling up if they're happy, but only during a certain part of the day:
With a certain Pokémon in the party
This is a unique condition: Mantyke evolves into Mantine when it levels up only if there is a Remoraid in user's party.
With high enough Beauty
This is also a unique condition: Feebas evolves into Milotic by leveling up if its Beauty stat is 170 or above.
With a certain gender and at a certain level
It is the third unique condition: Combee evolves into a Vespiquen if it is female. Male Combee do not evolve.
With an empty slot
This is the fourth unique condition: When Nincada evolves into Ninjask (at level 20), if there is an empty slot in the party, a Shedinja will appear. In Generation IV, the player must also have a spare Poké Ball in their bag.
Additional factors
Some Pokémon from branched evolution families evolve into different forms depending on some additional factors. These factors are not conditions for evolution, since they do not determine the possibility of evolution, but what the Pokémon will become after evolution.
- Burmy. This Pokémon evolves at level 20, but its new form is determined by its gender and cloak (and cloak changes according to the place, where it has battled last time).
- Tyrogue. This Pokémon evolves at level 20 depending on its stats.
- If its Defense is higher than Attack, it evolves into Hitmonchan
- If its Attack is higher than Defense, it evolves into Hitmonlee.
- If Attack is equal to Defense, it evolves into Hitmontop.
- Wurmple. It evolves at level 7 into Silcoon or Cascoon, depending on its personality value. This value is hidden, determined when Pokémon is caught and cannot be affected by the player. See the article about personality value for the exact formula.
For Espeon and Umbreon, see above.
Evolution via evolutionary stone
- Main article: Evolutionary stone
- See also: Pokémon that evolve by evolutionary stone
Some Pokémon evolve when they are exposed to an evolutionary stone. The stone may be applied at any time, thus causing an instant evolution.
However, as the player can decide whether and when to evolve his or her Pokémon (although the user can always decide it, since evolution can be canceled or prevented by using an Everstone), he or she must take the decision carefully: most Pokémon will no longer be able to learn certain moves when they evolve in this way, and some (like Raichu) cannot learn any moves by leveling up, although there are exceptions to this rule and certain moves are exclusive to the stone-evolved Pokémon.
Examples
- Vulpix + Fire Stone → Ninetales
- Poliwhirl + Water Stone → Poliwrath
- Pikachu + Thunder Stone → Raichu
- Weepinbell + Leaf Stone → Victreebel
- Nidorino + Moon Stone → Nidoking
- Gloom + Sun Stone → Bellossom
Usually there are no special requirements for stone-induced evolution, with only two exceptions: Kirlia and Snorunt. They may evolve when they hit a certain level at either gender, or...
| Kirlia | male or female | at level 30 | → Gardevoir |
| male only | + Dawn Stone | → Gallade | |
| Snorunt | male or female | at level 42 | → Glalie |
| female only | + Dawn Stone | → Froslass |
Note that sometimes the Oval Stone is said to be an evolutionary stone, because it is a stone and it is required for an evolution. However, technically Oval Stone is an evolution-inducing held item, which Happiny must be holding to evolve into Chansey when it levels up.
Evolution via trading
- Main article: Trade
- See also: Pokémon that evolve through trading
A select few Pokémon evolve only 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.
Examples:
A well-known mistranslation in the non-Japanese releases of the Generation I games suggested that after trading a man a Raichu, he said that it had evolved. This fueled speculation as to whether or not there would be a third stage to the Pikachu line in Generation II; a third stage was later realized in the form of a Baby Pokémon, Pichu.
Holding a certain item
- Main article: Evolution-inducing held item
- See also: Pokémon that evolve by trading with a held item
Some Pokémon evolve when traded only if the are holding a certain item. Like any evolution-inducing held item, the item disappears after the Pokémon evolves.
Examples
The following Pokémon evolve using this method:
- Slowpoke → Slowking: trade while holding King's Rock
- Onix → Steelix: trade while holding Metal Coat
- Electabuzz → Electivire: trade while holding Electirizer
- Porygon → Porygon2: trade while holding Up-Grade
- Clamperl → Huntail: trade while holding DeepSeaTooth
