Pokémon IVs: How Individual Values Work
Pokémon IVs are hidden numbers that represent a Pokémon’s individual strengths in each stat. IV stands for Individual Value, and every Pokémon has a separate value for HP, Attack, Defense, Special Attack, Special Defense and Speed.
That is why two Pokémon of the same species, level, Nature and EV spread can still show different stats. IVs are part of the Pokémon itself when it is generated, although modern games give you tools such as breeding, the Judge function and Hyper Training to make good stats much easier to obtain.
What range do Pokémon IVs use?

Pokémon IVs range from 0 to 31 in each of the six stats. A value of 31 is the natural maximum and is often described as a perfect IV. A value of 0 is the natural minimum. The difference becomes more noticeable at higher levels because IVs are included in the final stat calculation.
A Pokémon does not need six perfect values to be useful. Physical attackers may not care about Special Attack at all, while special attackers often have no reason to maximise Attack. In some competitive situations a deliberately low IV can even be preferable.
The official Pokémon training guide explains how a Pokémon’s individual strengths fit alongside Bottle Caps and Hyper Training when you are refining its stats.
How the Judge function describes Pokémon IVs
Modern games usually let you unlock a Judge function that replaces raw numbers with phrases. In Pokémon Sword and Shield, ratings such as Best, Fantastic, Very Good, Pretty Good, Decent and No Good correspond to ranges of IVs. Best means 31, while No Good means 0.
The exact interface and unlock condition change between games, but the purpose is the same: it lets you quickly identify whether a newly caught or bred Pokémon already has the important individual strengths you want.
Why zero IVs can be useful
Perfect Pokémon IVs are not automatically the goal in every stat. A special attacker can benefit from a 0 Attack IV because confusion damage and moves such as Foul Play can punish a high Attack stat. A slow Trick Room Pokémon may want a 0 Speed IV so it moves before faster Pokémon while Trick Room is active.
Those are specialised examples, but they explain why breeders sometimes save Pokémon marked No Good rather than releasing them. A 0 can be just as deliberate as a 31 when a team is built around a specific battle plan.
How breeding passes down Pokémon IVs
Breeding can pass a selection of the parents’ IVs to an Egg. The Destiny Knot is commonly used because it increases the number of inherited values, making it much easier to combine strong stats from two parents over several Eggs. This is one of the classic ways to create Pokémon with several perfect natural IVs.
Breeding remains important when the underlying value matters, because Hyper Training changes the stat performance without replacing the Pokémon’s natural IV for inheritance. A Hyper Trained stat therefore behaves like a perfect stat in battle but does not become a perfect breeding value.
How Hyper Training affects IVs
If the Pokémon is otherwise exactly what you want, Bottle Caps can be used for Hyper Training in games that support the system. The official Pokémon training guide for Sword and Shield describes Hyper Training as a way to maximise individual strengths using Bottle Caps.
This is especially useful for rare Pokémon, shinies, Legendary Pokémon and other catches that are difficult or impossible to breed normally. Pokémon IVs no longer have to be naturally perfect for that individual Pokémon to reach the same battle stat.
IVs are only one part of a final stat
Pokémon IVs work alongside base stats, level, Pokémon EVs and Pokémon Natures. Base stats describe the species, IVs describe the individual, EVs describe its training, and Nature modifies the growth of certain stats.
For casual story play, you can mostly ignore IVs. For raids and competitive teams, checking the important ones saves time and helps you understand whether a disappointing stat is caused by the Pokémon’s natural value, its EV spread, its Nature or simply its level.
When should you worry about Pokémon IVs?
Start checking them when you begin building Pokémon for high-level activities. Decide which attacking stat the Pokémon actually uses, whether Speed matters to the set, and which defensive stats need to be reliable. There is little value in spending resources perfecting a stat that never contributes to the role.
Pokémon IVs look intimidating because the raw numbers are hidden, but the system is simple once you separate it from EV training. Judge the useful stats, Hyper Train what needs fixing, and leave intentionally low values alone when they are part of the build.
