Gender (Japanese: 性別 sex) is a characteristic of Pokémon and humans in the Pokémon world.

In Generation I games, Nidoran♀ and Nidoran♂ were the only Pokémon shown to have a gender. Starting in the Generation II games, most Pokémon have a gender (including Pokémon previously transferred from Generation I games): male (Japanese: オス male) or female (Japanese: メス female); however, some species of Pokémon are gender unknown. The gender mechanic is fundamental to Pokémon breeding.

In the core series games, starting in Pokémon Crystal, the player can choose between a male (Japanese: 男性 male) or female (Japanese: 女性 female) player character. However, human men and women have appeared in all core series Pokémon games. Though only in the English versions of Pokémon GO, Blanche uniquely is the only human character not to have a specified gender.

Determining gender

One factor that determines gender is each Pokémon species's gender ratio, which is approximately how likely a Pokémon is a specific gender instead of the other.

Generation II

In Generation II, a Pokémon's gender is determined based solely on its physical Attack IV when compared to its gender ratio. A Pokémon is female if its physical Attack IV is less than or equal to its species' gender ratio, otherwise it is male. For species that are exclusively one gender or gender unknown, the calculation based on the physical Attack IV is ignored.

Due to this calculation, it is impossible to obtain a female Pokémon with high physical Attack, unless the Pokémon is a member of an all-female species like Jynx or Chansey. Starter Pokémon and others with a gender ratio of seven males to one female suffer the most, with the maximum physical Attack IV for a female Pokémon of those species being 1.

Pokémon from the Generation I games are assigned a gender using the same process when transferred to the Generation II games, used in Pokémon Stadium 2, or transferred from the Virtual Console games to Pokémon Bank. As a result, a Pokémon maintains its gender when transferred between the Generation I and II games (even though the gender is not shown in the Generation I games, aside from Nidoran♀ and Nidoran♂).

Generations III to V

00000000 00000000 00000000 00000000

From Generation III to Generation V, a Pokémon's gender is determined by the personality value's lowest eight digits (the lowest byte, highlighted in red above) of p in binary form. Mathematically, this can be derived by calculating p % 256. Below, this value will be referred to as pgender.

In a Pokémon species' data structure, there is a value called the gender threshold, a byte with a value ranging from 0 to 255. With the exception of a few special cases, pgender is compared to the gender threshold to determine if the Pokémon is male or female.

If the gender threshold is not a special value (0, 254, or 255), pgender is compared to the gender threshold. If pgender is greater than or equal to the gender threshold, the Pokémon is male, otherwise it is female. Because the comparison to determine gender is greater than or equal, Pokémon are slightly more likely to be male than they would be according to the ideal ratios.

If a species has a gender threshold of 255, all Pokémon of that species are gender unknown (such as Magnemite). If a species has a gender threshold of 254, it is a female-only species (such as Nidoran♀). If a species has a gender threshold of 0, it is a male-only species (such as Nidoran♂).

00000000 0 Male 100.00% 0.00%

From Pokémon Emerald onwards, if a Pokémon with Cute Charm is in the first place in the party (even if fainted), there is a 66.7% chance that the game will force an encountered Pokémon to be the opposite gender to the Pokémon with Cute Charm if it can be that gender. This does not affect a swarming Pokémon species or Pokémon found in Hidden Grottos.

Generation VI onward

From Generation VI onward, the gender threshold is compared to a random number between 1 and 252 (inclusive) instead of pgender (which is between 0 and 255); this causes Pokémon with a "1:1" gender ratio to actually be distributed according to the ideal ratio. All other Pokémon are more likely to be the more common gender than they would be according to their nominal ratio.

Gender differences

Main article: List of Pokémon with gender differences

Generation IV premiered minimal differences in sprite between two Pokémon of the same species. For example, a male Raichu will have the full tail seen in previous games, while the female is missing the very tip of it. Generations V and VI would introduce Pokémon with more drastic differences in appearance.

The only two Pokémon with gender differences that are not just aesthetic are Meowstic and Indeedee, who have different learnsets and sets of Abilities depending on its gender.

Meowstic

The male Meowstic has Prankster and the female Meowstic has Competitive as its Hidden Ability. At certain levels, they learn different moves from one another: the male Meowstic learns status moves, while the female Meowstic learns special moves. In Generations VI and VII, female Meowstic learned one gender-exclusive status move, Me First.

Indeedee differs more drastically by gender than Meowstic, with male and female Indeedee having slightly different base stats as well as learnsets. Male Indeedee have higher Attack, Special Attack, and Speed, while female Indeedee have higher Defense, Special Defense, and HP. While male Indeedee can learn the TM and TR moves Power Swap, Trick Room, Magic Room, Wonder Room, Tri Attack, and Encore, female Indeedee can learn Light Screen, Reflect, Safeguard, Guard Swap, and Baton Pass. The Egg Move Extrasensory is exclusive to male Indeedee while the Egg Moves Psycho Shift and Heal Pulse are exclusive to female Indeedee.

Single-gender Pokémon

Related species

The Nidoran family is a special case in terms of gender. Introduced in Generation I, before gender was known for all Pokémon, Nidoran♀ and Nidoran♂ are considered separate species of Pokémon and indeed have many differences, from appearance to moveset. However, Nidoran Eggs have a 50/50 chance of hatching into either Nidoran♀ or Nidoran♂.

In a manner similar to Nidoran, Eggs produced by Illumise may hatch into Volbeat. While Latias and Latios are in the Undiscovered Group in the games, likely due to being Legendary Pokémon, Latias have produced Eggs containing Latios in the anime, confirming that they are similarly related.

In battle

The Love Ball is more effective when catching Pokémon that are of the opposite (or same in Generation II, due to a programming error) gender of the player's Pokémon.

The following moves are dependent on gender:

Gen Move Category Contest Power Accuracy PP Target Description
II Attract Status Cute 100% 15 (max 24)
     
     
Any adjacent Pokémon
If it is the opposite gender of the user, the target becomes infatuated and less likely to attack.
IV Captivate Status Cute 100% 20 (max 32)
     
     
All adjacent foes
If any opposing Pokémon is the opposite gender of the user, it is charmed, which harshly lowers its Sp. Atk stat.
VIII G-Max Cuddle Physical Varies % 1 (max 1)
     
     
Any adjacent Pokémon
Deals damage and all opponents of the opposite gender of the user become infatuated.
VIII G-Max Cuddle Special Varies % 1 (max 1)
     
     
Any adjacent Pokémon
Deals damage and all opponents of the opposite gender of the user become infatuated.
All details are accurate to Generation VII games. For details that have changed between generations, please see an individual move's page. Target data assumes user is in the lower left.

The following Abilities are dependent on gender:

Gen Ability Description
III Cute Charm Contact with the Pokémon may cause infatuation.
IV Rivalry Becomes competitive and deals more damage to Pokémon of the same gender, but deals less to Pokémon of the opposite gender.
All details are accurate to Generation VII games. For details that have changed between generations, please see an individual Ability's page.

In side series games

Pokémon Stadium 2

Pokémon Stadium 2 may connect to Generation I or Generation II core series games via the Transfer Pak, and is compatible with Pokémon genders. While Generation I games don't identify Pokémon genders (other than Nidoran♀ and Nidoran♂), the gender displayed in Pokémon Stadium 2 is the same as in the core series Generation II games, which is determined by the Pokémon's physical Attack IV when compared to its gender ratio.

For instance, a Pikachu from Pokémon Red, Blue, or Yellow is shown as either male or female in Pokémon Stadium 2.

In spin-off games

Pokémon Mystery Dungeon series

Red and Blue Rescue Team

In Pokémon Mystery Dungeon: Red Rescue Team and Blue Rescue Team, there is no gender displayed for any Pokémon other than Nidoran♀ and Nidoran♂. There are no gender-based game mechanics in battle, therefore Attract and Cute Charm are able to infatuate any opponent.

Explorers of Time, Darkness, and Sky

In Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness and Pokémon Mystery Dungeon: Explorers of Sky, male Pokémon, as well as gender-unknown Pokémon (such as Magnemite), have a 1.5x bonus applied to move's base critical rate before other modifiers are applied, and at the same time all moves that target them have 263/256 (~1.03x) accuracy multiplier if no other accuracy or evasion modifiers are in effect. Barring those that are gender-locked, Pokémon encountered on odd dungeon floors will always be male, and Pokémon encountered on even floors will always be female.

In the anime

Prior to the introduction of the gender mechanic in the games, some Pokémon were already shown to be male or female. For instance, Meowth from the Team Rocket trio is male, while Meowzie is female.

Humans

 
Choosing to play as male or female in Pokémon Black and White
Main article: :Category:Characters by gender

In the games

Starting in Pokémon Crystal, players were given the option of choosing to play as a boy or girl Trainer at the start of the game. Since then, every game in the main series has included that choice. Starting in Pokémon Ruby, Sapphire, and Emerald, the opposite-gender player character can also be encountered in the game.

Some Trainer classes have male and female variants, such as Swimmers, while others appear to be counterparts, such as Campers and Picnickers. Others, such as Kimono Girls, have no opposite-gender counterpart.

Certain in-game events may differ depending on the player character's gender. For example, in Pokémon Black 2 and White 2, Curtis will be encountered if the player is female, and Yancy if the player is male. In Pokémon X and Y and Generation VII, availability of different clothing is gender-specific. Also, only the female player character has the option of changing their lip color using lipstick stored in a Makeup Bag in Generation VII.

Outside of battle facilities, the gender of a non-playable character often determines the default gender of their Pokémon. If the Pokémon's species has an even 1:1 gender ratio, then its gender will match its Trainer's; if the gender ratio is skewed, then the more common gender of the species will be used. Prior to Generation VII, Trainer classes for Double Battles are treated as male, even if both Trainers are female.

For some Trainers, especially Gym Leaders and the Elite Four since Generation V, the default genders have been overridden to give their teams a more balanced gender distribution. Oddly, the Elite Four in FireRed and LeafGreen and Gym Leaders in Emerald all use male-dominant teams in rematches, even though the female Trainers use all-female teams in their initial battles. In HeartGold and SoulSilver, Bugsy uses all-female teams despite being male.

Trivia

 
Nidoran♀ and Nidoran♂ show genders twice in Generation II, but only once in Generation III onward
  • Several Pokémon beside Nidoran were mentioned to have genders in Generation I games, prior to the introduction of the gender mechanic:
  • In Generation II, a Pokémon's gender was determined through its Attack IV. Due to this, a female Pokémon could never have a maximized Attack stat (unless they were a member of an all-female species, such as Smoochum), because female Pokémon were given the lower portion of the IV range. This also prevented female Pokémon of a species with a gender ratio of seven males to one female, such as starter Pokémon or Eevee, from being Shiny, due to that also being based partly on the Attack IV. Because of this, their Hidden Power is always a physical type. From Generation III onward, neither of these traits are determined by IVs, allowing for Pokémon species with two genders to have females with maximized Attack and simultaneously retain their chances of being Shiny.
  • Although its English and French names suggest that it is exclusively male, Mr. Mime may be of either gender; however, its name predates the introduction of gender to the series.
  • Since Azurill has a different gender ratio than Marill and Azumarill, one in three female Azurill used to become male after evolving into Marill, dependent on the personality value of the Azurill in question, though this no longer happens since Generation VI.
  • In the international versions of Generation II, due to how the battlefield display is programmed, Nidoran♂ and Nidoran♀ have their gender icon shown twice, once in their name, and once after the level. This does not occur in the Japanese and Korean games, however, as the gender icon was present after all Pokémon's names due to the shorter character limit there. This was addressed in all later generations, which prevent the gender icon from showing up when an un-nicknamed Nidoran of either gender is on the field.
  • One non-player character, Beauty Nova in Pokémon X and Y, is implied to be transgender. She says that she was reborn as a Beauty after originally being a Black Belt (a male-only Trainer class); in the Japanese versions, she credits this transformation to medical science.[1]
  • Despite being treated as gender-unknown Pokémon, Solgaleo and Lunala are described as being the male and female final forms of Cosmog, respectively.
