Category:Wikibooks Pokédex:Monster Egg Group
This category lists Pokémon in the Monster egg group. In order for two Pokémon to breed together, they must be in the same egg group, and, if not a Genderless Pokémon, be of opposite genders. However, Pokémon in the Unbreedable egg group may not breed together. Ditto may breed with any Pokémon not in the Unbreedable egg group, except with another Ditto.
