'''Individual values''' (Japanese: '''{{j|{{tt|個体値|こたいち}}}}''' ''individual values''), abbreviated '''IVs''', and sometimes referred to as '''determinant values''' (DVs) in the context of [[Generation I|Generations I]] and {{gen|II}}, are the Pokémon equivalent of {{wp|genes}}. They are instrumental in determining the [[stats]] of a Pokémon, being responsible for the large variation in stats among untrained Pokémon of the same species.

They have been officially known as '''{{j|{{tt|生まれつきの強さ|うまれつきのつよさ}}}}''' ''innate strengths'' in Japanese since at least {{game|Gold and Silver|s}}; in English, recent media from [[The Pokémon Company International]] has called them '''individual strengths'''.<ref>[http://www.pokemon.com/us/strategy/training-battle-ready-pokemon/ Training Battle-Ready Pokémon!]</ref><ref>[http://www.pokemon.com/us/strategy/the-details-of-discovering-pokemon-eggs/ The Details of Discovering Pokémon Eggs]</ref> In the games, the term '''potential''' is often used to allude to IVs, such as by the [[stats judge]].

Each of the six [[statistic|battle stats]] has an IV associated with it, with that IV coming into calculation alongside the Pokémon's [[base stats]], [[Nature]], and {{EV}}s to determine the actual stat number. A Pokémon's IVs are fixed when it is [[Pseudorandom number generation in Pokémon|generated by the game]] (i.e. when it is obtained as an {{pkmn|Egg}} from the [[Pokémon Day Care]], [[wild Pokémon|encountered in the wild]], or [[Gift Pokémon|given to the player by an NPC]]), and cannot be changed (although [[Hyper Training]] causes stats to become values corresponding the maximum IVs).

Due to this calculation, it is impossible to obtain a female Pokémon with high Attack, unless the Pokémon is a member of an all-female species like {{p|Jynx}} or {{p|Chansey}}. Starter Pokémon and others with a gender ratio of seven males to one female suffer the most, with the maximum Attack IV for a female Pokémon of those species being 1.

Starter Pokémon and others with a gender ratio of seven males to one female suffer the most, with the maximum Attack IV for a female Pokémon of those species being 1.
Gender ratios are actually somewhat skewed from the theoretical values. For example, a Pokémon with a supposed 1:1 gender ratio will actually be male 9/16 of the time and female 7/16 of the time (when IVs are completely random).

In {{g|X and Y}}, all Pokémon in the {{egg3|Undiscovered}} are guaranteed to have a perfect 31 in at least three of their individual values when caught in the wild or obtained as a gift (except via [[Mystery Gift]]). In {{g|Omega Ruby and Alpha Sapphire}}, this only applies to {{pkmn2|Legendary}} and [[Mythical Pokémon]]. In {{g|Sun and Moon}}, this applies to Legendary and Mythical Pokémon, [[Ultra Beast]]s, the [[guardian deities]], and {{p|Type: Null}}.

In [[Generation VII]], this applies to Legendary Pokémon, Mythical Pokémon, and [[Ultra Beast]]s.


In {{g|Sun and Moon}}, [[Hyper Training]] allows the player to make a Pokémon's stats act as if the Pokémon had maximum IVs. However, this does not actually change the IVs, so its true IVs are still used for the purposes of {{m|Hidden Power}} and {{pkmn|breeding}}.

====Breeding====
{{main|Pokémon breeding#Inheriting stats|Pokémon breeding → Inheriting stats}}
Starting in {{game|HeartGold and SoulSilver|s}}, a parent holding a [[EV-enhancing item|power item]] will pass the IV corresponding to the same stat to its children.
Starting in [[Generation VI]], if either of a Pokémon's parents were holding a [[Destiny Knot]], the child will inherit 5 of its 6 IVs from its parents.

A Pokémon's IVs can be evaluated using the [[Stats judge#In Pokémon GO|Appraisal]] option on the Pokémon screen.
