List of Pokémon with form differences
SomePokémon have majorvariations between individuals, known asforms. These variations all have differing appearances and are recognized by thePokédex. The process of form change allows some Pokémon to change between their different forms, such as withCastform, while other Pokémon have forms that they cannot change between, such asUnown. Other types of form differences includegender differences,regional forms,Mega Evolutions, andGigantamax forms.
Overview

Form differences were introduced inGeneration II, in which Unown was the only Pokémon to have them. All subsequentgenerations have introduced multiple Pokémon with form differences. Pokémon able to change between their forms were first introduced inGeneration III.
At times, these differences are purely cosmetic and have no bearing on the Pokémon's attributes besides its appearance; however, several Pokémon differ instats,type,Ability,moves they can learn, etc., depending on their form. Among these are severalLegendary andMythical Pokémon, whose alternate forms are usually named using the French word "Forme" instead.
Starting inPokémon HeartGold and SoulSilver, every official different form has a name given by thePokédex, thoughArceus,Genesect, andFurfrou's alternate forms were not recognized separately in the Pokédex untilPokémon Omega Ruby and Alpha Sapphire. InGenerations II,III, andIV, whichever form is encountered first will be the sprite displayed in the Pokédex by default; for example, if West SeaShellos was encountered first, its sprite will appear in the Pokédex by default, whereas if East Sea Shellos was encountered first, its sprite will. In Generation II, the Pokédex has a separateUnown Mode to show the forms of Unown. In Generation IV, the "forms" section was added to the individual entries of each Pokémon, showing form differences that have been encountered, as well asgender differences. InGeneration V, the forms section returns and displaysShiny Pokémon as separate forms (if they have been encountered); additionally, the sprite displayed in the Pokédex can be changed using the forms section. InPokémon Black and White, the forms section is only available after interacting withCedric Juniper inMistralton City, while inPokémon Black 2 and White 2, it is available from the start. Starting inGeneration VII, the Pokédex does not have a separate forms section; instead, a Pokémon's forms (including Shiny forms and gender differences) that have been encountered can be switched between in the Pokémon's entry, and this changes the image shown in the Pokédex.
Additionally, there exist form-like transformations and technical forms that are not recognized by the Pokédex, but otherwise appear or behave like unique forms or are treated as such in game code.

For more details, seeKoraidon → Biology andMiraidon → Biology.
Pokémon with technical forms
Some Pokémon have forms which are only distinguished internally within the game's programming. Most of these forms are not visually distinct from one another, but may still have an impact on gameplay. These forms are not included in the Pokédex (with the exception ofGreninja andRockruff's forms in the mobile version ofPokémon HOME).
Pikachu andEevee
Thepartner Pikachu and partner Eevee given to the player inPokémon: Let's Go, Pikachu! and Let's Go, Eevee! are each considered separate forms internally. They use higher quality models, have higher base stats, and are unable to evolve, along with many other minor differences.
For more details, seePikachu → Form data andEevee → Form data.
Mothim
Mothim has three forms internally, each corresponding to the three forms of Burmy it can evolve from.
For more details, seeMothim → Form data.
Greninja
Greninja with theAbilityBattle Bond are treated as a separate form to other Greninja, and cannot breed.
For more details, seeGreninja → Form data.
Zygarde
The 10% and 50% Formes of Zygarde with theAbilityAura Break are each treated as separate forms from the 10% and 50% Formes of Zygarde with the AbilityPower Construct. This explains why theAbility Capsule can't be used to change Zygarde's Ability, as only aZygarde Cube can.
For more details, seeZygarde → Form data.
Scatterbug andSpewpa
Vivillon patterns are each treated as separate forms. Because Vivillon's pattern is determined by the location the Scatterbug is generated in, each of Vivillon's 20 patterns has a corresponding form for both Scatterbug and Spewpa.
For more details, seeScatterbug → Form data andSpewpa → Form data.
Rockruff
Rockruff with theAbilityOwn Tempo are treated as a separate form to other Rockruff, and will always evolve into Dusk Form Lycanroc.
For more details, seeRockruff → Form data.

Totem Pokémon are a group of Pokémon found inAlola. While visually indistinct from their usual species, theirheight andweight is often much larger. Eleven of the twelve of these larger-sized variants, known as Totem-like Pokémon, can be obtained by the player. With exception ofWishiwashi, these Pokémon are programmed internally as unique forms. Totem-like Pokémon transferred toPokémon HOME will be reverted to their usual size.
For more details, seeTotem Pokémon → Totem-like Pokémon.
Unidentified properties
Many Pokémon have transformations and changes to them that appear similar to those of a form change or form-like transformation. However, these "forms" often go unnamed, and may just be a result of a Pokémon's normal biological properties.
Xerneas andYveltal
When Xerneas has exhausted too much life energy, it transforms into a tree and enters a deep slumber. Similarly, when Yveltal reaches the end of its lifespan, it steals the life energy of everything around it, then encases itself in a cocoon and falls into a slumber.
For more details, seeXerneas → Biology andYveltal → Biology.
Tapu Koko,Tapu Lele,Tapu Bulu, andTapu Fini

Theguardian deities have a uniqueZ-Move that no other species can use. During this Move, the tapu will make use ofAlola's own energy in the form ofZ-Power, allowing their tiki-like shell to be used as a head of a yellow giant, complete with arms and legs.
For more details, seeTapu Koko → Biology,Tapu Lele → Biology,Tapu Bulu → Biology, andTapu Fini → Biology.
Nihilego
Nihilego is anUltra Beast who is capable of physically merging with its host. It usually grasps onto the host's head, draining their energy and making them hostile. Due to unknown circumstances,Aether PresidentLusamine had been able to undergo a fusion with the UB, causing Nihilego to take on a drastically unique appearance. Lusamine's body had also changed with her body visible within Nihilego's bell and her legs dangling beneath it. This form has no known name, howeverThe Alola Region Artworks directs it under Lusamine's concept art, simply labeling it asルザミーネ (ウツロイド)Lusamine (Uturoid) or translated as:Lusamine (Nihilego). The internal name is known asMOTHERBEAST, using a combination of Lusamine's internal nameMOTHER, and the Ultra Beast internal name,BEAST.
For more details, seeNihilego → Biology.

In other games
Pokémon Shuffle
- Main article:List of Pokémon by Pokémon Shuffle list number
InPokémon Shuffle, Pokémon with different forms have differentSkills and can have different Attack Powers and max levels.
Most Pokémon with forms in the core series games also have those forms in Pokémon Shuffle. Many Pokémon have a "Winking" form, notably including most of thefirst partner Pokémon. There are also a few Pokémon with a "Spooky" or "Holiday" form. Pikachu has a large variety of forms, mostly unique to Pokémon Shuffle.
Pokémon GO
- Main article:List of Pokémon with form differences in Pokémon GO
The majority of Pokémon inPokémon GO have their forms determined at the time of capture and impossible to change, with the exceptions ofShaymin,Kyurem,Furfrou,Hoopa,Zygarde,Necrozma,Morpeko,Zacian, andZamazenta. Although every species has onePokédex entry each, a Pokémon is considered different from any of its alternate forms; this means that even if a player has one form of the Pokémon species registered in the Pokédex, an alternate form will still appear as a silhouette in the Nearby screen, and receiving one in atrade will be considered a Special Trade.
Trivia
- As ofGeneration IX, three Pokémon have form differences that remain unobtainable. These are:
- ???-typeArceus, which only existed in the code for theGeneration IV games and is unavailable without hacking.
- EternamaxEternatus, which is only seen in the climax ofPokémon Sword and Shield and when Eternatus usesEternabeam.
- Revavroom'sStarmobile forms, which are only seen being used by the bosses ofTeam Star.
- Some of the Pokémon with form differences have unique distinctions:
- Darmanitan andTauros are the only Pokémon whoseregional forms have further form differences.
- Hoopa is the only Mythical Pokémon whose form change outright increases base stats, rather than re-distributing them.
- Urshifu is the only Pokémon whoseGigantamax form has form differences.
- AlthoughToxtricity andAlcremie have multiple alternate forms, they each have only one Gigantamax form.
- Gimmighoul is the only Pokemon with multiple forms that have no bearing on the Pokémon/form of the Pokemon they evolve into.
- As a technicality, male Burmy may also fall under this unique distinction. As regardless of form, male Burmy will always evolve into Mothim. Burmy's form only dictates the outcome of Wormadam, exclusive to the Burmy who are female.
- Koraidon andMiraidon have the highest number of forms that are obtainable in some capacity yet unusable in battle, as they each use three forms solely for travel and are obtained in their fourth "low-power" forms, yet can only battle in their "high-power" forms.
- InPokémon Emerald, most Pokémon sprite animations have two frames. However, the three Pokémon in the game with form differences (Unown,Castform, andDeoxys) have only one frame for each of their forms, relying solely on rotation and bouncing effects for their animations, possibly due to space limitations. The same applies toSpinda, a Pokémon with differing appearances that are not classified as forms.
