Each of the six battle stats has an IV associated with it, with that IV coming into calculation alongside the Pokémon's [[base stats]] and {{EV}}s to determine the actual stat number. A Pokémon's IVs are determined when it is [[Pseudorandom number generation in Pokémon|generated by the game]]; 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]]. | Each of the six battle stats has an IV associated with it, with that IV coming into calculation alongside the Pokémon's [[base stats]] and {{EV}}s to determine the actual stat number.

==Generation I and II== | |||
In Generation I, | In Generation I and II, only four IVs stored for each individual Pokémon: Attack, Defense, Speed, and Special. Each of these is used to determine their associated stat, with the HP IV determined from the IVs stored for the other four. IVs range from 0-15 (in binary 0000-1111). | ||
The IVs' | The HP IV is calculated by taking the {{wp|least significant bit}} (the final binary digit) of the Attack, Defense, Speed, and Special IVs, then creating a binary string by placing them in that order. As such, a Pokémon with an odd-number Attack IV has 8 added to its HP IV, an odd-number Defense IV has 4 added, an odd-number Speed IV has 2 added, and an odd-number Special IV has 1 added. | ||
In Generation II, due to the Special stat being split into Special Attack and Special Defense, the Special IV is used for both Special Attack and Special Defense. | |||
In Generation II, several things aside from stats are also based on stats IVs. From [[Generation III]] onward, all of these except the [[type]] and [[power]] of {{m|Hidden Power}} are determined by the Pokémon's [[personality value]] instead. | |||
===Usage=== | |||
====Determination of stats==== | |||
In Generation I and II, a Pokémon's stats are determined according to the following formulas. | |||
<!-- These really should be DV and STATEXP instead of IV and EV, which were introduced in Gen III. --> | <!-- These really should be DV and STATEXP instead of IV and EV, which were introduced in Gen III. --> | ||

=== | ====Gender==== | ||
In Generation II, a Pokémon's [[gender]] is determined based solely on its Attack IV when compared to a [[List of Pokémon by gender ratio|value specific to each Pokémon species]]. A Pokémon is female if its Attack IV is less than or equal to its species' gender code, otherwise it is male. For species that are exclusively one gender or have no gender, the calculation based on the Attack IV is ignored. | |||
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. | |||
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). | |||

====Shininess==== | ====Shininess==== | ||
In Generation II, whether or not a Pokémon is Shiny is determined by its IVs. | |||
A Pokémon is Shiny if and only if both of the following conditions are met. | |||
*Its Defense, Speed, and Special IVs are all 10. | |||
*Its Attack IV is 2, 3, 6, 7, 10, 11, 14, or 15. | |||
Due to | Except when IVs are influenced due to {{pkmn|breeding}}, this set of IVs has a 1/8192 chance of occurring, which is also the likelihood of a wild Pokémon being Shiny in Generation III, IV, and V. Due to HP IV being calculated from the other IVs, a Shiny Pokémon's HP IV can only be 0 (if the Attack IV is even) or 8 (if the Attack IV is odd). | ||
Since 0 and 1 are not possible Attack IVs for a Shiny Pokémon, female Pokémon of {{cat|Pokémon with a gender ratio of seven males to one female|species with a seven male to one female ratio}} can never be Shiny in Generation II. | |||

====Unown's letter==== | ====Unown's letter==== | ||
{{p|Unown}}'s letter | In Generation II, {{p|Unown}}'s letter is taken from the combination of the center two bits of the Attack, Defense, Speed and Special IV {{wp|nibble}}s.

This integer will range from 0-25, corresponding to a letter in the {{wp|Latin alphabet}}, which will be the Unown's letter (where 0=A, 1=B, 2=C, ..., 23=X, 24=Y, 25=Z). | ||
In Generation II, due to this method of calculating Unown's letter and the way that {{Shiny}} Pokémon are determined, a Shiny Unown can only exist in the shape of the letter I or V. | In Generation II, due to this method of calculating Unown's letter and the way that {{Shiny}} Pokémon are determined, a Shiny Unown can only exist in the shape of the letter I or V. | ||

=== | ====Hidden Power==== | ||
{{main|Hidden Power (move)/Calculation}} | |||
The calculated [[Type]] and [[Power]] of the move {{m|Hidden Power}} is based on the IVs of the Pokémon. Hidden Power can be of any type aside from {{t|Normal}}, have a power between 31 and 70. The formula used in Generation II is different to the one used in later generations. | |||
The move's type is determined by the two {{wp|least significant bit}}s of the Attack and Defense IVs. The move's power is determined by the {{wp|most significant bit}} of each of the Pokémon's IVs, as well as the two least significant bits of the Special IVs. | |||
==Generation III onward== | |||
In Generation III, the IV system was completely overhauled; now, IVs range from 0-31 rather than 0-15, with HP and Special Defense getting their own independent IVs. | |||
The Generation III | Since IVs now have twice the range, they now have half the influence on a Pokémon's stats. The {{EV}} system overhaul and the addition of [[Nature]]s also result in small changes to formula used to determine stats. The [[personality value]] was introduced in Generation III, which handles a Pokémon's [[gender]] and {{Shiny|Shiny status}} instead, as well as several other properties; in Generation III, Unown's form was also handled using the personality value, but this is stored separately in Generation IV onward. | ||
The overhaul of the Pokémon data structure is one of the reasons why it was not made possible to trade between [[Generation II]] and [[Generation III]] games. | |||
===Usage=== | |||

====Hidden Power==== | |||
{{main|Hidden Power (move)/Calculation}} | |||
The calculated [[Type]] and [[Power]] of the move {{m|Hidden Power}} is based on the IVs of the Pokémon. Hidden Power can be of any type aside from {{t|Normal}}, and prior to [[Generation VI]], have a power between 30 and 70. | |||
The least significant bit of each IV determines the move's Type, and the second-least significant bit of each determines the move's Power. | |||
===Evaluation=== | |||
====Stats judge==== | |||
{{main|Stats judge}} | |||
From {{game|Emerald}} onward, there is a stats judge in the game in the region's battle facility or the city it is in. They give qualitative evaluations of the Pokémon's IVs. | |||
In {{game|Emerald}}, | *In {{game|Emerald}}, [[Stats judge#In Generation III|elderly man]] in the house north of the {{Gdis|Battle Frontier|III}}'s [[Pokémon Center]] will evaluate the Pokémon's IVs in a roundabout way. | ||
*In the [[Generation IV]] games, a man in the {{Gdis|Battle Tower|IV}} or {{gdis|Battle Frontier|IV}} will evaluate the Pokémon's IVs in a roundabout way. | |||
*In the [[Generation V]] games, an {{tc|Ace Trainer}} in the {{DL|Battle Subway|Gear Station}} will evaluate the Pokémon's IVs in a roundabout way, after the player enters the [[Hall of Fame]]. | |||
*In {{g|X and Y}}, an Ace Trainer in the [[Kiloude City]] [[Pokémon Center]] will evaluate the Pokémon's IVs in a roundabout way. | |||
*In {{g|Omega Ruby and Alpha Sapphire}}, an Ace Trainer in the [[Battle Resort]] [[Pokémon Center]] will evaluate the Pokémon's IVs in a roundabout way. | |||
Starting in Generation VI, the stats judge will also specifically note 0 IVs. | |||
====Characteristic==== | |||
{{main|Characteristic}} | |||
From Generation IV onward, each Pokémon has a [[characteristic]], a small blurb that indicates which of the Pokémon's IVs is the highest in a roundabout way. Rather than explicitly stating it, one of 30 of these short sentences is chosen, depending on which of the six stats the highest IV is in and how much more than a multiple of five it is. | |||

===Influence=== | |||
In [[Generation VI]], Pokémon in the {{egg2|Undiscovered}} are now guaranteed to have values of 31 in at least three of their stats when caught in the wild. Pokémon caught in the [[Friend Safari]] will have values of 31 in at least two of their stats. | |||
=== | |||
In | |||
{{ | |||
===Storage=== | |||
IVs are now all stored together as a single 32-bit value. Since IVs require 30 bits to be stored, the two {{wp|most significant bit}}s of this value are used to store other data. | |||
In Generation III, the most significant bit specifies which of two {{Abilities}} a Pokémon has (if it has potential to have more than one). If the Pokémon's species can have only one Ability in Generation III, the Ability bit is forced to 0 by the game (if it is forced to be 1, "No ability" will be listed as the Pokémon's Ability). | |||
In Generation IV onward, the most significant bit instead specifies whether or not the Pokémon is [[nickname]]d, while the second-most significant bit fulfills the same role as in Generation III. This allows an unnicknamed Pokémon traded to a game of a different language to retain its name in the language of the previous game, but still change its name upon evolution. | |||
The second-most significant bit specifies whether or not the Pokémon is an unhatched {{pkmn|Egg}} or not. | |||
The remaining 30 bits are the IVs, five bits apiece, in the order Sp. Def, Sp. Atk, Speed, Defense, Attack, and HP. | |||
