Sumeragi's Pumpkin

Base stats

The base stats are specific to the Pokémon species. Every individial Pokémon of the same species will have the same base stats, and this determines how good a species in general will be in certain areas. They usually increase when the Pokémon evolves, but otherwise cannot be changed.

Individual Values [IVs]

IVs can be thought of as the individual Pokémon's genetics. They are unique to the individual and cannot be changed. Values range from 0 to 31 and are a direct bonus to each stat. IVs can be passed down through breeding: three IVs will be inherited from parents, or five when one of them is holding a Destiny Knot.

Effort Values [EVs]

EVs are points gained by the Pokémon through effort and training. By visiting the Dojo, you can use Training Bags to power up. This is the only number you can directly affect. It ranges from 0 to 252, however the combined total cannot go higher than 510. Choose your training strategy wisely!
