To breed Pokémon, you must leave two Pokémon in the Daycare centre. The Daycare in the Kanto Region is located on the fourth of the Sevi Isles, the Daycare in the Sinnoh Region is located in Solaceon Town, and the Daycare in the Hoenn Region is located in Mauville City. In Generation 3, the egg will hatch to a Lv 5 Pokémon. In Generation 4, the egg will hatch into a Lv 1 Pokémon. If you deposit two Pokémon, there is a possibility that that they may leave an egg, depending on the circumstances.
- Both Pokémon must be in the same Egg group. If two different Pokémon are used in the breeding process, the baby Pokémon will be the same species as the mother.
- There must be one male and one female (unless the Ditto Rule is used).
- The Pokémon must be given enough time to breed. This time will vary. The Old Man standing outside the Daycare will tell you how well the two Pokémon get along. The more the Pokémon get along, the faster an egg will appear.
The Ditto Rule
The one Pokémon that ignores rule 2 is Ditto.A Ditto can be used as a substitute of another Pokémon. Some Pokémon are genderless, like Bronzong, and can breed with a Ditto. Other species like Nidoran♀ are male-only, thus breeding with a Ditto would yield an egg Nidoran. Any Pokémon not in the unbreedable group can breed with a Ditto. Dittos cannot be used to breed most Legendary Pokemon, however is the only method of obtaining Phione, by breeding a Ditto with a Manaphy.
The Nido Rule
Normally, the egg will always be the same species as the mother. However, if a Nidoran is breeding, and follows all the rules, there's is a 50% chance that the egg will hatch as a Nidoran (the male form of a Nidorina), and a 50% chance as female Nidorina.
This also works for
Incense Rule
If a Pokémon holds an incense when breeding, then you will get its baby form. There are quite a few Pokémon that can do this, including:
- Marill or Azumarill with Sea Incense to get Azurill (Gen 3 and 4)
- Wobbufett with Lax Incense to get Wynaut (Gen 3 and 4)
- Roselia or Roserade with Rose Incense to get Budew (Gen 4)
- Chimecho with Pure Incense to get Chingling (Gen 4)
- Sudowoodo with Rock Incense to get Bonsly (Gen 4)
- Mr. Mime with Odd Incense to get Mime Jr. (Gen 4)
- Chansey or Blissey with Luck Incense to get Happiny (Gen 4)
- Snorlax with Full Incense to get Munchlax (Gen 4)
- Mantine with Wave Incense to get Mantyke (Gen 4)
Inherited/Egg moves
When breeding, the mother passes her ability and species to her baby. The baby's father is the primary contributor to passing on moves. There are several ways a Pokémon can inherit moves. Inherited moves are moves that a Pokémon would not normally learn, but inherits through breeding. There are several ways for a Pokémon to inherit a move.
- If the father has learned a TM move, the baby will hatch with the TM move, assuming it is capable of learning that move.
- If the father knows a move that is on the offspring's egg move list, (a list of moves that can only be learned through breeding) then the baby will be born with the egg move.
- If both parents know a specific move on the baby's level-up move list, then the baby will hatch knowing that move.
Quick Hatching
In Emerald, Diamond, or Pearl if you carry around a Pokémon with the ability Magma Armour or Flame Body as well as the egg the number of steps needed to hatch eggs is halved.
Egg groups
All Pokémon belong to a group, but a particular Pokémon may be in more than one group. Two Pokémon can only breed if they are in the same egg group. Here's the list:
- Dragon
- Fairy-like
- Field
- Flying
- Genderless
- Human-like
- Indeterminate
- Insect
- Grass
- Mineral/ Rock
- Monster
- Unbreedable
- Water a
- Water b
- Water c
Pokémon fall this way into the groups:
Flying | Dragon | Fairy | Ground | Genderless | ||
---|---|---|---|---|---|---|
Grass | Human-Like | Indeterminate | Insect | Mineral/Rock | ||
Monster | Unbreedable | Water A | Water B | Water C | ||
