Daycare Pokémon pairs
Forum-Index → Help → Answered → Daycare Pokémon pairs- Egg Groups - Pokemon can only breed if their first Egg Groups are the same
- Gender - Pokemon can only breed with the opposite gender, or Ditto
- OT - To have higher breeding chances, the Pokemon need to have different Original Trainers
- Family/Siblings - To be compatible, the Pokemon cannot be siblings/brother and sister
- Species - To have higher breeding chances, the Pokemon must be the same species (not Pokedex number; for example, Lucario and Mega Lucario are not a perfect breeding pair)
The following messages show compatibility of pairs, in order of least compatible, to most compatible:
"The two prefer to play with other Pokémon than each other." / "The two seem to play with each other, but only as brother and sister."
"The two don't seem to like each other."
"The two seem to get along."
"The two seem to get along very well."
"The two seem to match perfectly."
