List of Pokémon with gender differences

Some species of Pokémon have differences in appearance due to gender in the Pokémon world, with noticeable differences between the males and females. With the exception of the differences between male and female Nidoran (which are considered distinct species), gender differences were introduced in Generation IV.

Two Meowstic present different appearances depending on their gender, as seen in the anime

Pyroar's gender difference in the anime, with the male and female respectively

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

In Pokémon Diamond, Pearl, and Platinum, at 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 subsequent games, they are displayed from the start.

Later generations would introduce far fewer Pokémon with gender differences, but those that were introduced varied much more drastically in appearance. Two Pokémon, Meowstic and Indeedee, even have different Abilities and learn different moves through leveling, TMs and breeding depending on their gender. Male and female Indeedee even have different stats. However, most Pokémon look identical despite their gender.
