pokemon go iv explained

Pokémon GO, at its core, is a game of collection and competition. While any trainer can catch a Charizard, not every Charizard is created equal. This hidden disparity is governed by a fundamental statistic known as Individual Values, or IVs. Understanding IVs is the key to transitioning from a casual collector to a strategic battler and optimizer. This article will explain what IVs are, how to find them, and crucially, how to interpret their real-world impact on your Pokémon.

What Are IVs? The Genetic Code of Your Pokémon

Every Pokémon species has base stats for Attack, Defense, and Stamina. A Charizard, for example, has inherently higher base Attack than a Blastoise. Individual Values are unique bonus points added on top of these base stats. Think of base stats as a species' blueprint and IVs as the unique genetic variation for each individual creature. Each of the three IVs can range from 0 to 15. A Pokémon with 15 Attack IV has 15 extra points added to its species' base Attack stat. This means two Pokémon of the same species, same level, can have noticeably different combat capabilities due to their IVs.

How to Find and Measure IVs: From Appraisal to Calculators

Pokémon GO does not display IVs as raw numbers. Instead, trainers must use the in-game Appraisal feature. By talking to your team leader (Candela, Blanche, or Spark), they will provide a verbal description and visual bars indicating the strength of each stat. Phrases like "Its stats exceed my calculations" or "It's a wonder!" correspond to high IV ranges. The appraised stat bars are divided into three segments, making a full bar equal to 15. For precise measurement, many trainers use third-party IV calculator apps or websites. These tools combine the appraisal data with the Pokémon's visible CP and HP, requiring a small amount of stardust to power up for exact results, to pinpoint the exact IV combination.

Interpreting IV Percentages: The 0% to 100% Scale

The cumulative total of a Pokémon's IVs is often expressed as a percentage. Since the maximum total is 45 (15+15+15), a percentage is calculated from that total. A "Hundo" or 100% IV Pokémon has a perfect 15/15/15 spread. Conversely, a "Nundo" (0/0/0) is a rare collector's item. This percentage is a quick, at-a-glance measure of overall genetic perfection. However, it is vital to understand that a 98% Pokémon (e.g., 15/15/14) performs nearly identically to a 100% in almost all scenarios. The difference in actual performance is often marginal, measured in single-digit HP or fractions of a second in raid completion time.

Attack, Defense, Stamina: The Role of Each Stat

Each IV stat influences a different aspect of battle. Attack IV increases the damage dealt by both Fast and Charged Attacks. A higher Attack IV can sometimes allow a Pokémon to reach a key "breakpoint" where its fast attack deals one more damage per hit against a specific raid boss. Defense IV reduces incoming damage. Stamina IV directly increases a Pokémon's HP total. In Player versus Player (PvP) battles, particularly in the Great and Ultra Leagues with CP caps, the relationship between these stats becomes nuanced. Often, a Pokémon with lower Attack but higher Defense and Stamina IVs can achieve a higher overall level while staying under the CP limit, resulting in greater bulk and more wins. This has led to the concept of "PvP optimal IVs," which are rarely perfect 100% spreads.

IVs in Practice: PvP, Raids, and the "Hundo" Hunt

The importance of IVs depends heavily on game mode. For raiding and Gym attacking, where the goal is maximum damage output as quickly as possible, high Attack IVs are generally prioritized. A perfect 15 Attack IV is most desirable here to secure those damage breakpoints. For defending Gyms, high Defense and Stamina are slightly more valuable for longevity, though motivation decay makes this less critical. The most strategic depth is found in PvP. In the Master League, where there is no CP cap, perfect 100% IV Pokémon are unequivocally best. However, for the Great and Ultra Leagues, the ideal IV spread often involves a low Attack IV (frequently 0 or 5) paired with maximum Defense and Stamina (15/15/15 or close). This allows the Pokémon to be powered up to a higher level within the CP cap, gaining more bulk.

Beyond IVs: The Bigger Picture of Pokémon Performance

While IVs are important, they are only one piece of the performance puzzle. A Pokémon's moveset is arguably more critical; a perfect IV Tyranitar with suboptimal moves will underperform a mediocre IV one with the ideal raiding moves. A Pokémon's level, represented by its CP arc and stardust cost, is also a more significant factor. Powering up a high-level, mediocre IV Pokémon is often more resource-efficient than investing in a low-level perfect one. Species and typing remain the foremost determinants of utility. A perfect IV Ledian will never outperform a mediocre IV Mewtwo. Therefore, IVs should be used as a tiebreaker between two otherwise identical Pokémon of the same species and moveset, or as a long-term optimization goal for end-game content.

Mastering IVs in Pokémon GO transforms the game from simple catching to strategic team building. It adds a layer of depth, giving purpose to catching multiple copies of the same species and rewarding careful analysis. By understanding what IVs represent, how to find them, and how they interact with game mechanics like CP caps, trainers can make informed decisions about where to invest their precious stardust and candy. The hunt for perfect IVs, or the perfect PvP IVs, becomes a compelling endgame pursuit, ensuring that every catch holds the potential for hidden excellence.
