In Pokémon GO, IVs (Individual Values) are hidden stats that determine a Pokémon's potential strength. They are important when powering up Pokémon for Raids, PvP, Gyms, and long-term investments, but they are not the only factor that decides whether a Pokémon is strong.
Players who want to prepare more resources can use TOPUPlive. TOPUPlive provides PokéCoins top-up with up to 63% OFF, helping players get more value when purchasing important items.
Every Pokémon has three hidden Individual Values:
IV Type | Effect | Max |
|---|---|---|
Attack | Increases damage output | 15 |
Defense | Reduces damage taken | 15 |
HP / Stamina | Increases total HP | 15 |
The total IV score ranges from 0 to 45.
The IV percentage formula is:
(Attack + Defense + HP) ÷ 45 × 100
Common terms:
Term | IV Spread | Meaning |
|---|---|---|
Hundo | 15/15/15 | Perfect Pokémon |
Nundo | 0/0/0 | Extremely rare collector Pokémon |
3★ Pokémon | 37–44 IV points | High-quality Pokémon |
Low Attack PvP Pokémon | 0/15/15 | Common PvP IV style |
IVs are added on top of a Pokémon's existing stats. A strong species with average IVs can often outperform a weak species with perfect IVs.
The importance of IVs depends on what you are doing. A common mistake is transferring a useful Pokémon because it is not perfect.

For PvE content:
Recommended priority:
Species + Moveset > Level > IVs
For example, a strong Raid attacker with 14/14/14 IVs is usually not significantly weaker than a perfect Hundo.

PvP works differently because of CP limits.
For:
Lower Attack with higher Defense and HP is often preferred.
Common PvP IV spreads:
The reason is that Attack increases CP faster, meaning lower Attack allows a Pokémon to reach a higher level while staying under the CP limit. A lower IV Pokémon can sometimes outperform a Hundo in PvP.

Master League has no CP limit.
The ideal choice is usually:
15/15/15
Perfect IV Legendary Pokémon are especially valuable here.
The easiest way to check IVs is through the in-game Appraisal feature.
Steps:
The appraisal screen shows:
Stars | Total IV | IV Percentage | Recommendation |
|---|---|---|---|
0★ | 0–22 | 0–48.9% | Usually transfer |
1★ | 23–29 | 51.1–64.4% | Low value |
2★ | 30–36 | 66.7–80% | Usable early |
3★ | 37–44 | 82.2–97.8% | Keep candidates |
4★ | 45 | 100% | Perfect Hundo |
A full glowing stat bar means that IV is 15.

The Pokémon search system makes sorting easier.
Useful filters include:
Search | Purpose |
|---|---|
4★ | Find Hundos |
3★ | Find strong Pokémon |
0attack | Find low Attack Pokémon for PvP |
4attack | Find Pokémon with 15 Attack |
defense15&hp15 | Find strong bulk Pokémon |
0attack&4defense&4hp | Search for classic PvP spreads |
These filters are especially useful after Community Days or large catching events.

A Hundo is a Pokémon with:
15 Attack + 15 Defense + 15 HP
They are valuable because they represent the maximum possible IV combination. However, hunting only Hundos is not always efficient.
Good reasons to keep a Hundo:
Do not ignore strong 90%+ Pokémon just because they are not perfect.

Different Pokémon sources have different IV minimums.
Source | Minimum IV | Hundo Chance |
|---|---|---|
Wild Pokémon | 0/0/0 | 1/4096 |
Weather Boosted | 4/4/4 | 1/1728 |
Eggs / Raids / Research | 10/10/10 | 1/216 |
Lucky Pokémon | 12/12/12 | 1/64 |
Lucky Pokémon are especially useful because they have better IV floors and require less Stardust to power up.

Shadow Pokémon are different from normal Pokémon.
Shadow bonus:
Because of the damage bonus, strong Shadow Pokémon are often among the best Raid attackers.
Keep:
Think carefully before Purifying because purification:
A 13/13/13 Shadow Pokémon can become a Hundo after purification, but keeping the Shadow version may provide better battle performance.

Most IV changes are limited.
Action | Changes IV? |
|---|---|
Power Up | No |
Evolution | No |
Trading | Yes, completely rerolls |
Purification | +2 to all stats |
Hyper Training | Improves selected stats |
Trading is the main way IVs can change naturally. Lucky Trades are especially valuable because they guarantee higher minimum IVs.

Instead of keeping everything, use these rules:
Category | Pokémon to Keep | Why Keep |
|---|---|---|
Always Keep | Hundos | Extremely rare and valuable for raids, gyms, and collection |
Shiny Pokémon | Rare collectibles that are difficult to obtain again | |
Lucky Pokémon | Require less Stardust and are useful for powering up | |
Costumed Pokémon | Limited-time collectibles that may not return | |
Strong Shadow Pokémon | High damage potential after powering up | |
Rare Pokémon | Hard-to-find Pokémon with collection value | |
Useful PvP IV Pokémon | Valuable for Great League, Ultra League, or Master League | |
Usually Keep | Strong Raid Attackers | Useful for Raid Battles and Mega/Legendary raids |
3★ Pokémon with useful species | Good candidates for future investment | |
Pokémon with Exclusive Moves | Special moves may be unavailable outside events | |
Usually Transfer | Low IV Common Pokémon | Easy to catch again and usually have little value |
Duplicate Pokémon without Useful Roles | Keep only the strongest or most useful copies | |
Weak Pokémon with Easy Availability | Can be replaced when better versions are caught |
Storage management becomes important during events, so knowing what to keep saves a lot of space. Trainers who need more PokéCoins can use TOPUPlive Pokémon GO top up, with discounts of up to 63%.

Avoid these mistakes:
A perfect IV Pokémon is exciting, but it does not automatically become the strongest choice.
The best IV Pokémon depends on the purpose. For Master League and many PvE attackers, 15/15/15 is ideal. For Great League and Ultra League, lower Attack with high Defense and HP is often better.
No. CP, species stats, moveset, and level usually matter more. IVs become more important when investing heavily.
Not necessarily. Keep useful species, strong attackers, PvP candidates, and rare Pokémon. A random 3★ Pokémon may still have little value.
Many Shadow Pokémon are stronger attackers because of the Shadow damage bonus. A good Shadow Pokémon can outperform a perfect normal Pokémon.
Only if the Pokémon is useful. A Hundo of a weak Pokémon is usually less valuable than a strong meta Pokémon with lower IVs.
Catch more Pokémon, complete Raids and Research, trade with friends, and check Pokémon with higher IV floors such as Eggs, Raids, and Lucky Trades.
IVs are an important part of Pokémon GO progression, but they should not control every decision. The strongest players understand when IVs matter and when other factors are more important. Focus on building strong teams, saving Stardust, choosing the right Pokémon to invest in, and using IV checks before expensive upgrades.
