Pokémon breeding is a strange and surprisingly unexplained phenomenon. All it takes is for two Pokémon that share an Egg Group and are of opposite genders to spend some time with one another and they may decide to breed. This is typically done through GM intervention, but if they are confined and allowed to mingle with one another unsupervised, it usually doesn’t take longer than a week, after which an Egg is produced.
- Nobody’s actually certain as to how Pokémon breed. They never do it when humans are around, and they seem to have an innate sense of attempts to capture this process on video and refrain from breeding. The process seems to happen very quickly, and the female Pokémon is never pregnant, so it is assumed that Pokémon eggs are produced through external fertilization. Most bafflingly, female Pokémon do not carry eggs inside their body, so where the eggs come from is a complete mystery.
Pokémon Eggs
A Pokémon Egg is always the same species as the female’s and hatches at the first evolutionary stage, unless one of the parents is a Ditto, in which case the Egg will be the non-Ditto parent’s species. Ditto cannot breed with other Ditto.
The Egg’s Nature, Ability, and Gender are decided based on the breeder’s (if any) Pokémon Education Rank. If their Rank is high enough, they are allowed to choose, otherwise it is up to the GM’s discretion.
- Nature may be determined by rolling 2d6, each representing which Stat is raised. May be picked by breeders with Adept Pokémon Education.
- Ability is decided from the species’ Basic Abilities. May be picked by breeders with Expert Pokémon Education.
- Gender may be determined by rolling 100 and checking its Gender Balance, seeing which percentage of the Pokémon are female. If the number rolled is lower than or matches that number, the Pokémon is Female; otherwise it is Male. May be picked by breeders with Master Pokémon Education.
- When the egg hatches, roll 1d100 to see if the Pokémon is Shiny; on a roll of either 1 or 100, the Pokémon is special in some way, determined by your GM. Feel free to make suggestions to them, though.
- If the parent that is not the same species as the Egg has any moves in its Natural Move List that appear on the Egg’s Tutor Move List, the Egg’s Tutor Moves become Natural Moves.
Eggs hatch at a Level equal to your Tier. Each Pokémon species has its own Hatch Rate.
Additionally, Pokémon that are bred don’t have any higher potential than Pokémon that are caught from the wild. Eugenics generally aren’t fun for cooperative games.
