A regional form (Japanese: リージョンフォーム Region Form), also known as a regional variant in Generation VII, is an alternate form of a Pokémon species that is found in a specific region. These forms differ from those found in the region where the Pokémon was introduced — even, in all cases so far, to the point of having a different type. As of Generation VIII, Pokémon can have the following regional forms:
- Alolan Form (Japanese: アローラのすがた Alola Form) in Alola, known as an Alola Form in Generation VII;
- Galarian Form (Japanese: ガラルのすがた Galar Form) in Galar;
- Hisuian Form (Japanese: ヒスイのすがた Hisui Form) in Hisui.
As of Generation VIII, 52 Pokémon are known to have regional forms, and 53 regional forms are known in total. Apart from Meowth, which has two, each Pokémon with a regional form has only one.
In the Alola, Galar, and Hisui regions, certain Pokémon species have regional forms. A Pokémon in these forms are described as such; for example, Sandshrew in its Alolan Form is referred to as Alolan Sandshrew and Ponyta in its Galarian Form is referred to as Galarian Ponyta. Although the original forms of these Pokémon are not normally identified by a separate name, people from regions that do have regional forms will usually refer to the original form of a given Pokémon in the same format.  According to the Pokédex, Alolan Vulpix goes by an older name: Keokeo.
Pokémon with regional forms have uniquely adapted to habitats that are different than those where its species naturally live in other parts of the world. As such, many things may be different about them, from their appearance and way of living to even their type, moves, Abilities, base stats, height, and weight. This is analogous to a form of real-world evolution known as peripatric speciation, where a population that is isolated from the rest of the species develops unique traits and eventually evolve into a new species.
When breeding Pokémon whose offspring have a regional form, the offspring will normally take on the form corresponding to the region in which it was bred, regardless of its parents' forms. However, if one of the parents of the same evolutionary family held an Everstone when the Egg was produced, the offspring will be the same form as that parent.
If a Pokémon without a regional form evolves into a Pokémon with a regional form, it will evolve into the form native to the region it is currently in.
In Pokémon Sun and Moon, if a Pokémon evolves from a species that does not have an Alolan Form to one that does, such as Cubone, it will always evolve into its Alolan Form and cannot evolve into its original form. In Pokémon Ultra Sun and Ultra Moon, the Pokémon will evolve into its Alolan Form while in Alola itself, but can also evolve into its original form while in Ultra Space.
Alolan Forms of Pokémon present in the Galar Pokédex are unavailable by normal means in Pokémon Sword and Shield and can be obtained by transferring them from Generation VII. Alolan forms of Pokémon included in The Isle of Armor expansion are available as rewards for finding hidden Alolan Diglett on the Isle of Armor, and Alolan Exeggutor, and Marowak can be obtained from in-game trades with Regina, in exchange for their respective Kantonian forms. In The Crown Tundra, certain Alolan Forms can be obtained from Dynamax Adventures. An Alolan Meowth also makes a cameo appearance in the NPC Pokémon Camp on Route 7.
List of Alolan Forms
While only Pokémon introduced in Kanto have Alolan Forms, Pokémon introduced both in and after Generation I can have Galarian Forms. Additionally, several Pokémon in their Galarian Forms have an evolution that their regular form does not.
List of Galarian Forms
A total of nineteen Galarian Forms were introduced in Generation VIII. Thirteen of these forms were introduced in the launch versions of Pokémon Sword and Shield, with the remaining six introduced through updates and downloadable content additions to the games.
Like in the Galar region, Pokémon introduced both in and after Generation I have Hisuian Forms. Notably, these forms were introduced after their region's debut, as Hisui is a version of the Sinnoh region from the distant past.
List of Hisuian Forms
A total of sixteen Hisuian Forms were introduced in Generation VIII.

New Pokémon Snap
In the anime
Alolan Pokémon were present in Pokémon the Series: Sun & Moon since the first episode. Ash first learned about them in The Guardian's Challenge!, where his class discussed the difference between Alolan Exeggutor and Exeggutor from other regions.
An Alolan Persian nicknamed Pershie first appeared in That's Why the Litten is a Scamp!, where it was shown antagonizing a wild Litten. It reappeared in Dummy, You Shrunk the Kids! and We Know Where You're Going, Eevee!.
Multiple Alolan Rattata and Raticate appeared in To Top a Totem!, where they were harassing a farmer on Melemele Island, stealing his crops. Hala tasked Ash with finding a solution to this problem that doesn't involve battling the pests. Instead, Ash chose to battle the Verdant Cavern Totem Pokémon, Gumshoos, and enlisted its help to scare the Rattata and Raticate away.
Lillie received a Pokémon Egg in Lillie's Egg-xhilarating Challenge!. It hatched into an Alolan Vulpix she nicknamed Snowy in Racing to a Big Event!. After capturing it in the following episode, Lillie took her first steps towards overcoming her fear of touching Pokémon.
In Getting the Band Back Together!, an Alolan Dugtrio appeared under the ownership of Professor Kukui's old friend, DJ Leo. Their musical performance drew the adoration of a wild Alolan Diglett, who later joined as another member of their DJ group.
In A Team-on-Team Tussle!, Team Rocket fought a trio of Team Skull Grunts over a Darkinium Z protected by a Totem Alolan Raticate and Ally Alolan Rattata and Raticate. While Jessie and James are ultimately unsuccessful in defeating the Totem, Meowth is able to steal the Z-Crystal while it is distracted.
An Alolan Geodude debuted in Treasure Hunt, Akala Style!, where Ash attempted to catch it. After a short battle, the Alolan Geodude punched Ash's Poké Ball into his face with a Thunder Punch and then ran away.
In A Crowning Moment of Truth!, while Ash and his classmates were visiting Wela Volcano Park for the Wela Fire Festival, the festivities were interrupted by a wild Alolan Marowak, who stole the Wela Crown used in a ceremony. While Kiawe and his Turtonator were defeated by it during their first challenge, they were able to defeat it in a rematch thanks to Turtonator's newly learned Shell Smash. After being defeated, Marowak gave back the crown and asked to join Kiawe's party.
A wild Alolan Meowth appeared in Acting True to Form!, where it came to Team Rocket looking for a worthy master. It manipulated Jessie and James into turning against Meowth by showing off its abilities, and also earned their favor when they realized it could use their Darkinium Z. When Giovanni and Matori contacted the trio for a report on their activities, the Alolan Meowth became intrigued by them. To this end, it slipped away, stole Meowth's savings, and flew to Kanto to reach Team Rocket HQ, where Matori made it her assistant due to its craftiness.
More Alolan Sandshrew appeared in Not Caving Under Pressure! in the caverns underneath Mount Lanakila. Lillie befriended a particularly large Sandshrew, and helped it reclaim its territory from an aggressive Tyranitar. After the battle, Sophocles's Charjabug found an Ice Stone, which the Sandshrew promptly used to evolve into Sandslash. Sandslash rewarded Lillie with an Icium Z as a token of gratitude.
Alolan Geodude and Graveler appeared in Sparking Confusion! at Wela Volcano Park, having been driven out by rock hunters attempting to mine the caves in the area for the food the Pokémon eat. The hunters were attacked by their leader, an Alolan Golem, who began attacking indiscriminately. Thanks to the Ultra Guardians' Metang, however, Ash, Kiawe, and Sophocles were able to calm the group of Alolan Pokémon and stop the magnetic interference coming from the Park. The leader Golem later joined a trio of Hikers who volunteered to help with future patrols of Wela Volcano Park.
A Galarian Ponyta and a Galarian Rapidash appeared in The Tale of You and Glimwood Tangle!. While within Glimwood Tangle, Chloe followed a Galarian Ponyta where it led her to an injured Galarian Rapidash.

In the TCG
Regional forms are featured in the Pokémon Trading Card Game as Alolan, Galarian, and Hisuian Pokémon. Starting with the Sword and Shield Series, evolutions exclusive to regional forms are referred to with the same descriptors used for their pre-evolutions (for example, Galarian is used as a descriptor for both Galarian Form Pokémon and their evolutions).
- Main article: Variant Pokémon
Prior to Generation VII, there were already certain Pokémon that had variations depending on their native geographical area, but, unlike regional forms, these Pokémon do not appear to have any functional difference from their original forms; rather, their differences are purely aesthetic, with their type, moves, Abilities, height, and weight remaining the same.
- The Generation I Pokédex entries for Arbok state that there are six variations of its face-like hood markings that differ between areas. Eight designs are known, but only three have appeared in the core series games (with a fourth in Pokémon Ranger). In Pokémon Adventures, Arbok gains a special ability depending on its pattern.
- In Sinnoh, Shellos and Gastrodon have different appearances on each side of Mt. Coronet. East Sea Shellos and Gastrodon only appear east of Mt. Coronet, whereas West Sea Shellos and Gastrodon only appear on the west side.
- Mantyke's Pokédex entry in Pokémon Pearl says that the pattern on its back varies from region to region. While it has the same appearance in all Generation IV games (due to using the same sprites), the "face" from Generation V onward appears wider.
- Vivillon, which was introduced in Generation VI, has a different appearance depending on where the game it was created in is from in the real world.
- In the anime episode Poké Ball Peril, a number of alternately colored Pokémon were seen on Valencia Island, including Butterfree, Raticate, Nidoran♂, Nidoran♀, Vileplume, Paras, and Weepinbell. Professor Ivy, the Pokémon Professor of the Orange Archipelago, studies these variations.
- The episode Fly Me to the Moon featured Pidgey native to Pudgy Pidgey Isle that were too heavy to fly due to an abundance of food and a lack of predators.
- In the Pokémon Adventures round Off Course with Corsola, Bill mentioned that Kanto and Johto share many of the same Pokémon, but their colors and patterns are different between regions.
δ Delta Species
- Main article: δ Delta Species (TCG)
The Pokémon Trading Card Game introduced Delta Species Pokémon in Generation III. Like regional forms, these Pokémon would undergo a type change, but their appearance would stay generally the same. The backstory of EX Delta Species states that these changes were not due to natural adaptation but rather a mutation brought on by exposure to electromagnetic waves.
This seems to be an exclusive phenomenon on the island of Holon, the aforementioned waves a product of experiments by scientists in the area searching for the Mythical Pokémon Mew. Delta Species Pokémon appeared in the TCG from EX Delta Species to EX Dragon Frontiers.
- In Pokémon Sun, Moon, Ultra Sun, and Ultra Moon, when a Pokémon undergoes evolution into a regional form, the background in the evolution animation is green, as opposed to the blue background used for all other Pokémon. Conversely, when a Pokémon Egg hatches into a regional form, the background is blue instead of yellow. Additionally, a different arrangement of the evolution music is played in both of these situations.
- In contrast to other regional forms, Galarian Zigzagoon is the original form of its respective species.
- No regional forms are Bug-type.
- Meowth is the Pokémon with the most regional forms, with two (Alolan and Galarian).
- Meowth is also the only Pokémon to have both a regional form and a Gigantamax form.
- Geodude's evolutionary line is the only three-stage evolutionary line in which all members have a regional form.
- All fully evolved Galarian Forms and/or their regional evolved forms have a signature move or a signature Ability.
- Slowpoke is the only Pokémon:
- with a regional form that has a branched evolution.
- to lose a type, rather than gaining or replacing one, in its regional form.
- Slowbro is the only Pokémon to have both a regional form and a Mega Evolution. In Pokémon GO, which features both, Galarian Slowbro cannot Mega Evolve.
- The Legendary birds are the only Legendary Pokémon with regional forms.
- Decidueye is the only Pokémon introduced after Generation VI to have a regional form.
- Generations IV and VIII are the only generations to not introduce any Pokémon that have regional forms.
- Goodra is the only pseudo-legendary Pokémon to have a regional form.
- Hisuian Sneasel is the only regional form to have gender differences.
- Although Basculin's White-Striped Form is not considered to be a regional form, its Pokédex entry in Pokémon Legends: Arceus implies that it technically is one.
- In the TCG, Basculin cards featuring the White-Striped form use the name "Hisuian Basculin".
- If White-Striped Basculin is considered a regional form, it is the only regional form whose type is exactly the same as its original form.
In other languages
- Hau refers to the Meowth the player's mom owns as a "Kantonian Meowth" in Pokémon Sun, Moon, Ultra Sun and Ultra Moon.
- In Pokémon Sword and Shield, a Team Yell Grunt in Spikemuth will offer to trade the player a Mr. Mime, which he refers to as a "Kantonian Mr. Mime".
