List of Pokémon with gender differences

Although most Pokémon look identical regardless of gender, some species have differences in appearance due to gender, with noticeable differences between the males and females. Gender differences were introduced in Generation IV.

These differences are a reference to sexual dimorphism, which is commonly seen in many real organisms and may offer some clues to their biology and behavior.

Generation IV, in addition to introducing new Pokémon with gender differences, also modified several older Pokémon to have gender differences. In most cases, the male version retained the original design while the female was altered. However, the inverse is true for Dodrio, Meganium, Xatu, Aipom, Torchic, Beautifly, Ludicolo, Meditite, Medicham, and Milotic. These Pokémon, as well as Bidoof, Bibarel, Combee, Ambipom, Gible, Gabite, and Garchomp, use their female designs for their official artwork, while other Pokémon with gender differences introduced in the first four generations use the male designs. (This cannot be determined for Buizel and Floatzel, as their backs are not shown in their official artwork, though Buizel debuted featuring its male design in the ninth movie.)

Later generations would introduce far fewer Pokémon with gender differences, but those that were introduced differ much more drastically in appearance and have separate official artwork and menu sprites for each gender. Starting in Generation VI, some Pokémon even have different Abilities, base stats, and/or moves they can learn depending on their gender. These gender differences are usually considered to be entirely separate forms.

Starting in Generation IV, certain Pokémon's Evolution is also affected by their gender. Burmy evolves into Wormadam if it is female or Mothim if it is male. Only female Combee and Salandit can evolve into Vespiquen and Salazzle, respectively, with the males unable to evolve at all. Only male Kirlia can evolve into Gallade, though either gender can evolve into Gardevoir; similarly, only female Snorunt can evolve into Froslass, though either gender can evolve into Glalie. However, Combee is the only one of these Pokémon to have a visual gender difference.

As of Generation IX, there are a total of 102 Pokémon with gender differences.

Male has a large mane shaped like the kanji character 大 ō (big or great) or 火 hi (fire), a stockier body, and half-brown front legs. Female has long, flowing hair similar to a ponytail and mostly-brown legs.
0678	Meowstic
Males are mostly blue with white highlights, the inverse of females. Male's eyes are green with light blue sclerae, while female's are red and yellow. The moves Meowstic can learn vary by gender, with males learning more status moves and females learning more damaging moves. Male Meowstic have the Hidden Ability Prankster, while female Meowstic have the Hidden Ability Competitive. In Pokémon Sword and Shield, all wild Meowstic are male in Sword and female in Shield. However, evolving Espurr allows both genders to be obtained in either version.

Generation VIII

There are two Generation VIII Pokémon with gender differences.

#	Name	Gender
Difference		Male	Female
0876	Indeedee
Males have lowered eyes, a triangular mouth pointing upwards like a frown, and more black on their torso, made to resemble a suit. Females have wider eyes, a triangular mouth pointing downwards like a smile, and more white on their torso, made to resemble an apron. Male Indeedee have higher Attack, Special Attack, and Speed, while female Indeedee have higher Defense, Special Defense, and HP. The two genders also have different moves and Abilities. In Pokémon Sword and Shield, all wild Indeedee are male in Sword and female in Shield. However, breeding and Dynamax Adventures allow both genders to be obtained in either version.
0902	Basculegion
Males have red accents, fierce-looking eyes, longer barbels, and two additional growths on their chin resembling a stubble. Females have pale-blue accents, sad-looking eyes, shorter barbels, and additional accents around their lips and eyes. Male Basculegion have higher Attack, while female Basculegion have higher Special Attack.

Generation IX

There is one Generation IX Pokémon with gender differences.

#	Name	Gender
Difference		Male	Female
0916	Oinkologne
Females have more brown bodies while males have a darker gray complexion. Male Oinkologne have a larger left ear which often covers their left eye, and have a more magenta shade of pink for their hooves and snout. Male Oinkologne are also slightly plumper than the females, and have a differently shaped tail bobble. Male Oinkologne may have the Ability Lingering Aroma, while female Oinkologne may have the Ability Aroma Veil. The two forms learn the same moves by leveling up, yet the female form learns them at earlier levels and also learns Yawn before Take Down. The two forms also have different stats, with males having higher Attack and Defense and females having higher HP and Sp. Def. They also have different cries.

In the Pokédex

Gender differences can be viewed in the Pokédex as forms. In Pokémon Diamond, Pearl, and Platinum, in the gate to Canalave City, Professor Rowan's assistant upgrades the player's Pokédex to be able to display form differences, including gender differences. In other games, they can be viewed from the start. As with other form differences, the player can register a gender difference in their Pokédex by obtaining it, or by seeing it in battle having obtained any form of the Pokémon.

From Generation IV to Generation VI, the Pokédex has a "forms" section in which both the male and female of the Pokémon are shown (for Pokémon that can be either gender), even if there is no gender difference, with "Male" and "Female" displayed as the form names. Starting in Generation VII, only Pokémon with gender differences have them shown as separate forms in the Pokédex; the gender currently shown is indicated by a male or female gender symbol being shown in the entry, with Pokémon that do not have gender differences (and can be either gender) having both symbols displayed. Most gender differences are not given form names, with the exception of Pokémon that have functional differences between genders (Meowstic, Indeedee, Basculegion, and Oinkologne), which use "Male" and "Female" as form names. This is also the case for the Pokédex in Pokémon Bank and the Nintendo Switch version of Pokémon HOME. However, Pokémon Legends: Z-A's Pokédex does not feature this distinction, with all Pokémon that have gender differences using the "Male" and "Female" form names.

In the mobile version of Pokémon HOME, most gender differences cannot be scrolled through like other forms; instead, all Pokémon that are not gender unknown have male and/or female symbols on their entries showing which genders they can have, and the player can tap these symbols to view any gender differences the Pokémon has. The exceptions are again Meowstic, Indeedee, Basculegion, and Oinkologne, whose gender differences are treated as entirely separate forms that can be scrolled through like other forms. In addition to these Pokémon, the app's Pokémon Guidebook feature also treats the gender differences of Unfezant, Frillish, Jellicent, and Pyroar as entirely separate forms, though their forms are not given names (whereas Meowstic, Indeedee, Basculegion, and Oinkologne use the "Male" and "Female" form names). Certain other official sources (such as websites and guidebooks) consider all of these Pokémon's gender differences as separate forms and use the "Male" and "Female" form names for them.

In the Pokémon HOME Pokédex, when viewing the entries for Quagsire, Torchic, Bidoof, Buizel, and Floatzel, the player can "rotate" the Pokémon by pressing the right stick (in the Nintendo Switch version) or tapping a rotation icon (in the mobile version), which changes the Pokémon's render to one with its back turned so that its gender difference can be seen more easily (in Bidoof's case) or at all (in the other cases).

Most Pokémon use the same Pokédex entry for both genders. Starting in Pokémon Sword and Shield, certain Pokémon have different entries for each gender, namely Meowstic, Indeedee, and Oinkologne. Basculegion uses the same entry for both genders in Pokémon Legends: Arceus, but has different entries for each gender in Pokémon Scarlet and Violet. Additionally, in the data for Pokémon Sword and Shield, female Unfezant has an unused Pokédex entry for Pokémon Sword, female Frillish has an unused entry for Pokémon Shield, and female Jellicent has unused entries for both versions, but in the final game, these Pokémon use the same Pokédex entries for both genders.

Trivia

Nidoran♀ and Nidoran♂ are gendered counterparts in a similar vein to gender differences, but they are considered two separate species. They were introduced in Generation I, prior to the introduction of gender as a mechanic in Generation II and of gender differences in Generation IV. Notably, Eggs produced by Nidoran♀ or Nidoran♂ can hatch into either Pokémon. A similar male-female gendered counterpart pair is Volbeat and Illumise, who also can produce Eggs containing each other.
- The male-female pairs Tauros and Miltank, as well as Latios and Latias, can also be considered gendered counterparts, though they cannot produce Eggs containing each other.
Some Pokémon with gender differences have unique distinctions:
- Garchomp is the only pseudo-legendary Pokémon to have a gender difference.
- Hisuian Sneasel is the only regional form of a Pokémon to have a gender difference.
- The Torchic evolutionary line is the only first partner Pokémon line where all of its members have gender differences.
- Politoed is the only Pokémon with gender differences from a branched Evolution line that evolves from a Pokémon without gender differences.
Fairy is the only type that lacks a Pokémon with gender differences.
Generation IV introduced the most Pokémon with gender differences, with a total of 31.
- It was also the first generation to introduce gender-based Evolution, and the first to introduce new gender differences to Pokémon established in previous generations.
Generation IX introduced the fewest Pokémon with gender differences of generations that introduced Pokémon with gender differences, introducing only one.

Generation VII is the only generation that did not introduce any new Pokémon that have gender differences. However, it did introduce a new gender difference for Eevee that was initially exclusive to the player's partner Eevee.
No Mega Evolutions or Gigantamax forms have gender differences, even if other forms of the same species do.
Despite having prominent gender differences, Hippopotas and Hippowdon only have artwork and a menu sprite for the male of the species.
- No female Hippowdon have ever appeared in the animated series.
Despite Spinda not having any gender differences, the Rotom Pokédex displays separate models for male and female Spinda, using whichever spot pattern the player caught first for each gender.
Some Pokémon with gender differences evolve into Pokémon that do not have gender differences, namely Pikachu evolving into Alolan Raichu, Golbat evolving into Crobat, Gloom evolving into Bellossom, Scyther evolving into Kleavor, Eevee evolving into the Eeveelutions, Murkrow evolving into Honchkrow, Girafarig evolving into Farigiraf, Gligar evolving into Gliscor, Hisuian Sneasel evolving into Sneasler, and Ursaring evolving into Ursaluna.
Although Krookodile has no gender differences in the games, in Fuecoco…Becomes a Crook?!, a Krookodile who plays the role of "mother" in a litter of Sandile and Krokorok has pink eyelashes.
