Understanding Egg Group Connections

The Pokémon breeding system divides all breedable species into 15 egg groups. Many Pokémon belong to two groups simultaneously, and these dual-group Pokémon act as bridges that connect otherwise isolated groups. The connection matrix above shows exactly how many Pokémon bridge each pair.

Why Egg Group Bridges Matter

When a target Pokémon needs an egg move from a species in a different egg group, you must find a bridge Pokémon that belongs to both groups. For example, a Pokémon in both the Monster and Water 1 groups can pass moves between those two populations. The more bridge Pokémon exist between two groups, the more breeding chain options you have.

The 15 Egg Groups

  • Breedable groups (13) -- Monster, Water 1, Water 2, Water 3, Bug, Flying, Field, Fairy, Grass, Human-Like, Mineral, Amorphous, and Dragon
  • Ditto -- breeds with any breedable Pokémon but cannot pass egg moves
  • No Eggs -- includes most Legendaries, Mythicals, and baby Pokémon; cannot breed at all
