Individual values or IVs can determine if a Pokémon is stronger than another Pokémon of the same species, as they are unique to each Pokémon obtained. They have a range from 0 to 15. The 3 individual values are Attack, Defense, and Stamina. The overall Appraisal is based on the sum of these three IVs. Each Pokémon species has base stats, which are listed on the individual Pokémon pages. The base stats are the lowest possible IV for that species. If a Pokémon's stats matches the base value, they are considered to have an IV of zero.
