EVs, IVs, and Natures are determining factors that help your Pokemon reach their full potential in Pokemon Scarlet and Violet (SV). Read on to learn about how these stats are explained in this article, how all the values that affect stats, and how to maximize each of them for Gen 9 competitive play!
List of Contents
| Value | Explanation |
|---|---|
| EVs (Effort Values) | ・Hidden value that adds points to each of a Pokemon's main stats. ・Battle wild Pokemon to acquire EVs. |
| IVs (Individual Values) | ・Hidden value that calculates the Stats based on the Pokemon's Base Stats and EVs. ・Values are hidden by default but you can check a Pokemon's IV using the Judge Function. |
| Natures | ・Affects the growth of two different stats (Attack, Defense, Special Attack, Special Defense) by increasing one stat by 10% and decreasing another by 10%. ・You can check a Pokemon's Nature usually in the summary menu. |
EVs, IVs and Natures all contribute to a Pokemon achieving its full potential. Having a good understanding of these three, and implementing them, will ensure that your Pokemon will be fit for battle.

EVs, or Effort Values, are hidden values which add points to each of a Pokemon's six main stats (HP, Attack, Defense, Special Attack, Special Defense, and Speed). Pokemon acquire EVs naturally by battling other Pokemon throughout the game.
Pokemon can acquire a total of 508 EVs, with a maximum of 252 EVs in each stat.
If you want your Pokemon to reach its full potential, meaningful allocation of these values would be ideal.

IV is an abbreviation for Individual Value, a hidden value which is combined with a Pokemon's Base Stats and EVs to calculate the Stats which are visible to players and used in battle.
Unlike EVs, IVs are determined randomly for each Pokemon, and are generally uncontrollable by the player. IVs are valued at 0 to 31 for each stat, where 0 is the worst number and 31 is the best number. Pokemon with high IVs in a stat will have a higher than normal value in that stat.
Pokemon's IVs are invisible by default, but in recent games, you can check your Pokemon's IVs by unlocking the Judge Function.

A Pokemon's Nature will affect the growth of two of its different stats (Attack, Defense, Special Attack, Special Defense). Nature will increase the growth of one of the stats by 10%, while decreasing the growth of another by 10%
If your Pokemon is using moves that are predominantly Physical, then it's best to get a Nature that increases its Attack stat, while decreasing its Sp. Attack stat.
In these cases, Adamant is recommended for Physical attackers, while Modest is recommended for Special attackers.
A Pokemon such as Hariyama will benefit from a Nature that increases its Attack, so it is best for it to have a nature that decreases its Special Attack since Hariyama does not use that stat.
| Nature | Increased Stat | Decreased Stat |
|---|---|---|
| Adamant | Attack | Sp. Attack |
| Bashful | - | - |
| Bold | Defense | Attack |
| Brave | Attack | Speed |
| Calm | Sp. Defense | Attack |
| Careful | Sp. Defense | Sp. Attack |
| Docile | - | - |
| Gentle | Sp. Defense | Defense |
| Hardy | - | - |
| Hasty | Speed | Defense |
| Impish | Defense | Sp. Attack |
| Jolly | Speed | Sp. Attack |
| Lax | Defense | Sp. Defense |
| Lonely | Attack | Defense |
| Mild | Sp. Attack | Defense |
| Modest | Sp. Attack | Attack |
| Naive | Speed | Sp. Defense |
| Naughty | Attack | Sp. Defense |
| Quiet | Sp. Attack | Speed |
| Quirky | - | - |
| Rash | Sp. Attack | Sp. Defense |
| Relaxed | Defense | Speed |
| Serious | - | - |
| Sassy | Sp. Defense | Speed |
| Timid | Speed | Attack |
We truly see the results of a Pokemon's training (or lack of) at Level 100, when all the factors (EVs, IVs and Nature) are added together.
At level 100, a Pokemon gets +1 point to a stat for every 4 EVs. and +1 point for every 1 IV.
A Salamence, with a 100 Base Speed Stat, for example, will have vastly different Speed stats based on how it is trained.
![]() Salamence |
|||
| Base Speed: 100 | |||
|---|---|---|---|
| IVs in Speed | EVs in Speed | Nature | Speed at Level 100 |
| 0 | 0 | Neutral | 205 |
| 31 (+31 Points) |
0 | Neutral | 236 |
| 31 (+31 Points) |
252 (+63 Points) |
Neutral | 299 |
| 31 (+31 Points) |
252 (+63 Points) |
+Speed (+10%) |
328 |
A Salamence with perfect IVs, maxed out EVs, and a Speed-boosting Nature (such as Jolly or Timid), will always outspeed Pokemon with a lower base speed than it, no matter how well they are trained for Speed.
Pokemon such as Hydreigon (98 Base Speed), if fully trained in Speed, will always be outsped by our Salamence if it is also fully trained.

On this same note, Salamence fully trained in Speed will never outspeed a Pokemon that has a higher base Speed if that Pokemon is also fully-trained in Speed.
