Which Pokémon can breed together?

Two Pokémon that share at least one of the 15 egg groups and are opposite genders can leave an Egg at the Day Care or Picnic. Ditto breeds with any breedable Pokémon regardless of egg group, and the offspring is always the non-Ditto parent's species.

Which Pokémon cannot breed?

Anything in the No Eggs group cannot breed at all, whatever the partner.

Why do dual egg groups matter?

Many Pokémon belong to two egg groups, which bridges otherwise unrelated species so an egg move can be passed along a chain.

How Pokémon breeding compatibility works

Pokémon breeding follows a strict set of rules built around 15 egg groups. Two Pokémon can produce an Egg at the Day Care or Picnic if they share at least one egg group and are opposite genders. Select any two Pokémon above to instantly check whether they are compatible.

The role of Ditto and the no-eggs group

Ditto can breed with any breedable Pokémon regardless of egg group, making it the most versatile breeding partner. The offspring always matches the non-Ditto parent's species. On the other end, Pokémon in the "no-eggs" group cannot breed at all, which covers most Legendary and Mythical Pokémon as well as baby Pokémon like Pichu and Togepi.

Why egg groups matter

Move inheritance: egg moves can only be passed between compatible breeding partners
IV breeding: parents pass down Individual Values, so choosing compatible high-IV parents matters
Dual egg groups: many Pokémon belong to two egg groups, creating bridges for passing moves between unrelated species
Genderless Pokémon: can only breed with Ditto, limiting their breeding chain options

The ledger above lists every egg group with its species count and how many other groups it reaches through dual-group species. Open a row to browse the members of that group and drop one straight into the parent B slot.
