How Natures Work in Pokémon LeafGreen
Natures were introduced in Generation III, so they are part of the core mechanics in Pokémon LeafGreen. Every Pokémon receives one nature when it is generated, and the nature normally remains fixed for that Pokémon. There are 25 total natures, divided into 20 stat-changing natures and five neutral natures.
A stat-changing nature raises one stat by 10% and lowers another by 10% when the final stats are calculated. The affected stats are Attack, Defense, Special Attack, Special Defense, and Speed. HP is never raised or lowered by a nature.
The nature bonus is most noticeable on Pokémon that are trained for a specific role. A physical attacker usually wants more Attack, while a special attacker generally prefers more Special Attack. Fast Pokémon may gain more from a Speed-boosting nature than from a small increase to one of their attacking stats.
Attack
Choose a boosting nature for Pokémon that rely mainly on physical moves such as Earthquake, Return, or Brick Break.
Defense
Defense-boosting natures help Pokémon that need to withstand physical attacks and stay active for longer battles.
Special Attack
Special attackers benefit from natures that raise Special Attack for moves such as Flamethrower, Surf, and Psychic.
Speed
Speed-boosting natures can help a Pokémon move before important opponents during the main story or competitive battles.
In LeafGreen, move categories are determined by move type. All Fire moves are special, while all Fighting moves are physical, regardless of the individual move.
The physical and special split used in later Pokémon games does not apply to LeafGreen. This makes nature selection more dependent on move type. For example, Charizard’s Fire attacks use Special Attack, while its Flying and Fighting attacks use Attack.
| Stat | Nature can raise it | Nature can lower it | Common role |
|---|---|---|---|
| Attack | Yes | Yes | Physical damage |
| Defense | Yes | Yes | Physical durability |
| Special Attack | Yes | Yes | Special damage |
| Special Defense | Yes | Yes | Special durability |
| Speed | Yes | Yes | Moving first |
| HP | No | No | Overall endurance |
Pokémon LeafGreen Nature Chart
The fastest way to identify a nature is to find the stat you want to raise and the stat you can afford to lower. The chart below lists every nature by its increase and decrease. The five natures that raise and lower the same stat are neutral in practice.
| Nature | Increases | Decreases | General use |
|---|---|---|---|
| Adamant | Attack | Special Attack | Physical attackers |
| Bashful | Special Attack | Special Attack | Neutral |
| Bold | Defense | Attack | Physical walls |
| Brave | Attack | Speed | Slow physical attackers |
| Calm | Special Defense | Attack | Special walls |
| Careful | Special Defense | Special Attack | Physical attackers with bulk |
| Docile | Defense | Defense | Neutral |
| Gentle | Special Defense | Defense | Specially bulky Pokémon |
| Hardy | Attack | Attack | Neutral |
| Hasty | Speed | Defense | Fast mixed attackers |
| Impish | Defense | Special Attack | Physical walls |
| Jolly | Speed | Special Attack | Fast physical attackers |
| Lax | Defense | Special Defense | Physically durable Pokémon |
| Lonely | Attack | Defense | Physical attackers |
| Mild | Special Attack | Defense | Special attackers |
| Modest | Special Attack | Attack | Special attackers |
| Naive | Speed | Special Defense | Fast mixed attackers |
| Naughty | Attack | Special Defense | Physical attackers |
| Quiet | Special Attack | Speed | Slow special attackers |
| Quirky | Special Defense | Special Defense | Neutral |
| Rash | Special Attack | Special Defense | Special attackers |
| Relaxed | Defense | Speed | Slow defensive Pokémon |
| Sassy | Special Defense | Speed | Slow special walls |
| Serious | Speed | Speed | Neutral |
| Timid | Speed | Attack | Fast special attackers |
A neutral nature does not provide a stat advantage, but it is not harmful for a normal playthrough. Story battles are forgiving enough that a strong moveset, appropriate levels, and good type coverage usually matter more than having an ideal nature.
A nature’s name does not reveal its effect. Always check the raised and lowered stats rather than assuming that a personality description predicts performance.
You can also use a stat-pair approach:
| Desired boost | Common choices | Best fit |
|---|---|---|
| Attack | Adamant, Lonely, Naughty, Brave | Physical damage dealers |
| Defense | Bold, Impish, Lax, Relaxed | Defensive or stall-oriented Pokémon |
| Special Attack | Modest, Mild, Rash, Quiet | Special damage dealers |
| Special Defense | Calm, Careful, Gentle, Sassy | Specially durable Pokémon |
| Speed | Timid, Jolly, Hasty, Naive | Fast attackers and sweepers |
Best Natures for Common LeafGreen Roles
There is no single best nature for every Pokémon. The correct choice depends on a Pokémon’s strongest stats, its move types, and whether you want maximum damage, additional bulk, or better Speed.
For a straightforward in-game team, offensive natures are usually the easiest to use. They improve the stat you rely on most while reducing a stat that receives less use. Defensive natures are more valuable when you expect a Pokémon to switch into attacks repeatedly or set up status effects.
| Battle role | Recommended nature | Raised stat | Lowered stat |
|---|---|---|---|
| Physical attacker | Adamant | Attack | Special Attack |
| Fast physical attacker | Jolly | Speed | Special Attack |
| Special attacker | Modest | Special Attack | Attack |
| Fast special attacker | Timid | Speed | Attack |
| Physical wall | Impish | Defense | Special Attack |
| Special wall | Calm | Special Defense | Attack |
| Slow physical attacker | Brave | Attack | Speed |
| Slow special attacker | Quiet | Special Attack | Speed |
| Fast mixed attacker | Naive | Speed | Special Defense |
| Bulky mixed attacker | Hasty | Speed | Defense |
Starter Considerations
Bulbasaur commonly appreciates Modest if it focuses on Grass and Poison special moves. Calm can also work for a more defensive setup. Charmander can use Modest because Fire attacks are special in LeafGreen, while Timid is useful when Speed is the priority. Squirtle often fits Modest because Water moves are special, although Bold supports a more defensive approach.
These are recommendations rather than requirements. A starter with a neutral nature can still complete the story, defeat the Elite Four, and contribute to a well-built team.
Physical and Special Examples
Many Kanto Pokémon use a mixture of move types, so examine the complete moveset before choosing. A Pokémon that uses Earthquake, Rock Slide, and Brick Break gains more from Attack. A Pokémon built around Surf, Ice Beam, Thunderbolt, or Psychic benefits from Special Attack.
| Pokémon style | Useful nature | Why it works |
|---|---|---|
| Physical Charizard | Lonely or Naughty | Raises Attack for physical coverage |
| Special Charizard | Modest or Timid | Supports Fire and other special moves |
| Physical Nidoking | Adamant | Improves physical coverage |
| Special Nidoking | Modest | Strengthens special type-based attacks |
| Defensive Venusaur | Bold or Calm | Adds physical or special resilience |
| Fast Jolteon | Timid | Raises Speed while lowering unused Attack |
| Physical Snorlax | Adamant or Careful | Improves Attack or special durability |
| Bulky Lapras | Modest, Calm, or Bold | Supports damage or defensive utility |
Raise the stat your main moves use, then lower a stat that contributes least to the Pokémon’s intended role.
Avoid selecting a nature only because it is popular. For example, Adamant is excellent for a physical attacker but reduces Special Attack, which can weaken a Pokémon that depends on special moves in Generation III.
Step-by-Step Nature Planning
Use this process when evaluating a Pokémon before committing to a moveset or training plan. It works for a starter, a caught Pokémon, or a team member intended for postgame battles.
Identify the Main Attacking Stat
Review the moves you plan to use. Physical moves rely on Attack, while special moves rely on Special Attack in LeafGreen because move categories are tied to type.
Check the Pokémon’s Role
Decide whether the Pokémon should deal damage, move quickly, absorb hits, spread status, or perform a mixed role. A defensive Pokémon may value Defense or Special Defense over an offensive stat.
Choose the Boosting Stat
Select a nature that raises the most important stat. Modest, Adamant, Timid, and Jolly are common offensive choices because they clearly support special, physical, or Speed-focused builds.
Accept the Least Important Reduction
Confirm that the lowered stat will not damage the planned role. Do not use Timid on a Pokémon that needs physical Attack, and do not use Adamant on a special-focused moveset without a clear reason.
Review the Final Moveset
Recheck the choice after selecting moves. If the moveset changes from physical to special, the ideal nature may change as well.
A mixed attacker requires more judgment. Naive raises Speed and lowers Special Defense, while Hasty raises Speed and lowers Defense. Choose the reduction that affects fewer expected matchups. If the Pokémon is already vulnerable to physical attacks, Hasty may be risky; if special defense is less important, Naive may be more suitable.
| Build question | If the answer is yes | Nature direction |
|---|---|---|
| Does the Pokémon use mostly physical moves? | Attack is the main damage stat | Adamant or Jolly |
| Does it use mostly special moves? | Special Attack is the main damage stat | Modest or Timid |
| Does it need to survive physical hits? | Physical durability is central | Bold or Impish |
| Does it need to survive special hits? | Special durability is central | Calm or Careful |
| Does it use both attacking categories? | Speed or balanced damage matters | Naive, Hasty, or neutral |
Do not delay your adventure searching for an ideal nature unless you enjoy optimization. Team balance, type coverage, levels, and reliable moves usually have a larger practical impact.
Berry Flavors and Nature Preferences
A Pokémon’s nature also determines which berry flavor it likes and dislikes. Each flavor corresponds to one stat. The flavor associated with the raised stat is preferred, while the flavor associated with the lowered stat is disliked.
This mechanic is separate from battle performance. Berry preferences do not change the nature’s stat effect, and a berry preference should not be used as the main reason to select a Pokémon for your team.
| Stat | Preferred flavor when raised | Disliked flavor when lowered |
|---|---|---|
| Attack | Spicy | Spicy |
| Defense | Sour | Sour |
| Speed | Sweet | Sweet |
| Special Attack | Dry | Dry |
| Special Defense | Bitter | Bitter |
For example, a Sassy Pokémon raises Special Defense and lowers Speed. It prefers Bitter flavors and dislikes Sweet flavors. A Timid Pokémon raises Speed and lowers Attack, so its preferences correspond to Sweet and Spicy.
Neutral natures raise and lower the same stat. Their berry likes and dislikes still reflect that stat pairing, even though the final battle stats do not receive a meaningful increase or decrease.
Use berry flavor preferences as a small optimization detail. For story progression, prioritize the nature’s stat effect and the Pokémon’s actual moveset.
Nature Selection Checklist and FAQ
Before building a team around a particular Pokémon, verify the important details rather than relying on the nature’s name alone.
Nature Planning Checklist:
- Identify whether the main moves use Attack or Special Attack
- Decide whether Speed, offense, or bulk is the highest priority
- Check which stat the chosen nature lowers
- Confirm that the lowered stat is not important to the moveset
- Review the nature again after finalizing the Pokémon’s moves
| Situation | Strong starting choice | Main trade-off |
|---|---|---|
| Physical sweeper | Adamant | Loses Special Attack |
| Special sweeper | Modest | Loses Attack |
| Fast physical attacker | Jolly | Loses Special Attack |
| Fast special attacker | Timid | Loses Attack |
| Defensive physical build | Impish or Bold | Loses an offensive stat |
| Defensive special build | Calm or Careful | Loses an offensive stat |
| Slow heavy hitter | Brave or Quiet | Loses Speed |
| Mixed attacker | Naive or Hasty | Loses one defensive stat |
Q: What are the best pokemon leafgreen natures for a normal playthrough?
Adamant is a strong general choice for physical attackers, Modest suits special attackers, Jolly helps fast physical Pokémon, and Timid supports fast special Pokémon. Neutral natures remain usable when the rest of the team is well balanced.
Q: Do natures affect HP in Pokémon LeafGreen?
No. Natures can affect Attack, Defense, Special Attack, Special Defense, or Speed, but they never directly raise or lower HP.
Q: Why does physical and special move type matter so much?
LeafGreen uses the Generation III system, where move categories are determined by type. Fire, Water, Electric, Grass, Ice, Psychic, Dragon, and Dark moves are special, while Normal, Fighting, Flying, Poison, Ground, Rock, Bug, Ghost, and Steel moves are physical.
Q: Can a Pokémon’s nature be changed in LeafGreen?
No modern nature-changing feature is available in LeafGreen. A Pokémon’s nature is normally fixed when it is obtained, so choose another Pokémon if a specific nature is important to your plan.
A nature is only one part of a Pokémon’s performance. Avoid replacing a useful team member solely because its nature is neutral or imperfect.
For most players, the best approach is simple: match the nature to the moveset, protect the Pokémon’s most important role, and keep the team’s type coverage in mind. Once those decisions are aligned, nature bonuses become a useful advantage instead of a source of unnecessary reset hunting.
