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.

No breeding needed.
The move tutor in the Colosseum Marketplace teaches Supersonic to Qwilfish for $35,000 or 50 BP. You reach the Battle Colosseum after the Arc Badge.
One breeding gets Supersonic onto Qwilfish.

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.
