Egg move chains

Pick a Pokémon and one of its egg moves. You get the shortest breeding chain to it, starting from a father you can catch.

RaichuElectricFairy, Field
It hatches as Pichu, so these are Pichu's egg moves.
No breeding needed.
The move tutor in the Colosseum Marketplace teaches Disarming Voice to Raichu for $35,000 or 50 BP. You reach the Battle Colosseum after the Arc Badge.
One breeding gets Disarming Voice onto Raichu.

    Any female of these works as well: Raichu, Raichu-Alola.
    The egg hatches as Pichu knowing Disarming Voice. Evolve it into Raichu. It keeps the move.
  3. Raichu with Disarming Voice.

How breeding works here

  • Leave a male and a female that share an egg group at the Lagoona Day Care. The egg hatches as the mother's first stage.
  • Either parent passes on an egg move it knows, however it learned it.
  • A Pokémon that is male only or genderless breeds with Ditto. Ditto passes on nothing.
  • Pokémon from codes, the roulette, Looao or tokens cannot breed.
  • Some babies need an incense on the mother (or on the parent paired with Ditto): Munchlax needs a Full Incense, Azurill a Sea Incense.
