Breeding
Complete PokeMMO breeding guide: mechanics, IV calculator and compatible Pokemon by egg group.
How does breeding work?
In PokeMMO, breeding lets you create a Pokemon with specific IVs, natures and moves. Two Pokemon of the same egg group and opposite genders are given to the Daycare Man. The offspring will be the female parent's species (or non-Ditto parent).
Warning: both parents are consumed during breeding. They are not returned.
IV Inheritance
Each parent can hold 1 Power Item. This guarantees the corresponding IV is passed down. With 2 braces (one per parent), 2 IVs are guaranteed, plus 1 random IV inherited from a parent.
Averaged IVs
Non-inherited IVs are calculated as the average of both parents' IVs (rounded down). This is why using 1x31 parents with the right IV and braces is essential.
Nature Inheritance
By giving an Everstone to a parent, its nature is passed to the offspring.
Egg Moves
The offspring can inherit special moves if the father knows them. Check egg moves in the Pokedex.
Hidden Abilities
A hidden ability has about a 60% chance to be passed if the female parent has it. A male holder can only pass it when bred with a Ditto.
Shiny Breeding
Two non-shiny parents can produce a shiny at normal odds. Two shiny parents guarantee a shiny offspring.

Select the desired IVs and find out how many base Pokemon you need, the number of breeds and the total cost.
Desired IVs at 31
Advanced options (nature, Ditto, prices...)
Forcing a nature doubles the number of base Pokemon needed.
With Ditto, half of the base Pokemon are replaced by 1x31 Dittos (often more expensive on the GTL).
Gender ratio
Starters and some rare Pokemon have a 87.5/12.5 ratio (more expensive).
