Every Pokémon caught or hatched comes with a specific personality trait known as its Nature. While these traits might seem like simple flavor text—describing a creature as "Jolly," "Adamant," or "Modest"—they are, in fact, one of the most critical mathematical foundations in the game. A Pokémon's nature provides a 10% increase to one primary stat and a 10% decrease to another. In a competitive landscape where a single point of Speed determines who moves first, or a sliver of Attack power determines a one-hit knockout (OHKO), understanding the natures Pokemon chart is non-negotiable.

Since their introduction in Generation III, natures have defined the ceiling of a Pokémon's potential. As of 2026, even with the accessibility of modern training tools, the fundamental math remains the same. This article breaks down every nature, its impact on competitive archetypes, and how to optimize your team's growth.

The Core Mechanics of Natures

A nature affects five of the six primary stats: Attack, Defense, Special Attack, Special Defense, and Speed. HP (Hit Points) is never affected by nature. In the modern game interface, you can identify these effects at a glance: the stat highlighted in red is receiving the 10% boost, while the stat in blue is suffering the 10% penalty.

Five of the twenty-five natures are "neutral," meaning they increase and decrease the same stat, resulting in no net change. In high-level play, these are almost universally avoided, as they represent a missed opportunity to specialize a Pokémon's role.

Master Natures Pokemon Chart

To make this data actionable, the following chart is organized by the stat being boosted. This allows you to quickly identify which nature fits your Pokémon's intended role.

Attack-Boosting Natures (Physical Attackers)

These natures are the go-to choices for physical sweepers like Garchomp or Zacian, who rely on moves like Earthquake or Behemoth Blade.

Nature Increases Decreases Favorite Flavor Disliked Flavor
Adamant Attack Sp. Atk Spicy Dry
Brave Attack Speed Spicy Sweet
Lonely Attack Defense Spicy Sour
Naughty Attack Sp. Def Spicy Bitter
  • Competitive Note: Adamant is the gold standard for physical attackers that don't need maximum Speed to be effective. Brave is exclusively used in Trick Room teams to ensure the Pokémon moves first under the reversed speed dimensions.

Defense-Boosting Natures (Physical Walls)

Use these for Pokémon intended to soak up physical hits, such as Toxapex or Corviknight.

Nature Increases Decreases Favorite Flavor Disliked Flavor
Bold Defense Attack Sour Spicy
Impish Defense Sp. Atk Sour Dry
Relaxed Defense Speed Sour Sweet
Lax Defense Sp. Def Sour Bitter
  • Competitive Note: Bold is preferred for defensive Pokémon that only use Special moves (or no attacking moves at all), while Impish is the choice for defensive units that still want to deal some physical damage (e.g., using Body Press).

Special Attack-Boosting Natures (Special Sweepers)

Ideal for glass cannons like Gengar or Chi-Yu that dominate with moves like Shadow Ball or Overheat.

Nature Increases Decreases Favorite Flavor Disliked Flavor
Modest Sp. Atk Attack Dry Spicy
Quiet Sp. Atk Speed Dry Sweet
Mild Sp. Atk Defense Dry Sour
Rash Sp. Atk Sp. Def Dry Bitter
  • Competitive Note: Modest is the most common choice here. Since Special attackers rarely use their physical Attack stat, the 10% penalty is essentially "free" with no downside.

Special Defense-Boosting Natures (Special Tanks)

For Pokémon like Blissey or Sylveon that act as a shield against elemental blasts.

Nature Increases Decreases Favorite Flavor Disliked Flavor
Calm Sp. Def Attack Bitter Spicy
Careful Sp. Def Sp. Atk Bitter Dry
Sassy Sp. Def Speed Bitter Sweet
Gentle Sp. Def Defense Bitter Sour
n* Competitive Note: Calm and Careful follow the same logic as the Defense-boosting group—choose based on whether your Pokémon uses physical or special moves to avoid hindering your own damage output.

Speed-Boosting Natures (The Speed Creep)

In many formats, Speed is the most important stat. These natures allow you to "Speed Tie" or outpace threats in the same base speed tier.

Nature Increases Decreases Favorite Flavor Disliked Flavor
Timid Speed Attack Sweet Spicy
Jolly Speed Sp. Atk Sweet Dry
Hasty Speed Defense Sweet Sour
Naive Speed Sp. Def Sweet Bitter
  • Competitive Note: Timid (for Special users) and Jolly (for Physical users) are arguably the most used natures in the entire game. Naive and Hasty are niche choices reserved for "Mixed Attackers" who need to keep both Attack and Special Attack stats high while still being fast.

Neutral Natures (The Ineffective Five)

These natures provide no competitive advantage.

Nature Effect
Hardy Increases Attack / Decreases Attack
Docile Increases Defense / Decreases Defense
Serious Increases Speed / Decreases Speed
Bashful Increases Sp. Atk / Decreases Sp. Atk
Quirky Increases Sp. Def / Decreases Sp. Def

Why Flavor and Taste Matter

Natures also dictate a Pokémon’s flavor preference, which might seem trivial until you consider the "Pinch Berries" (Figy, Wiki, Mago, Aguav, and Iapapa). These berries restore 33% (or 50% in older generations) of HP when the Pokémon is at low health. However, if a Pokémon eats a berry with a flavor it dislikes, it will become confused.

For example, if you give a Figy Berry (Spicy) to a Pokémon with a Modest nature, it will heal, but it will also become confused because Modest natures dislike Spicy flavors. This can lose you a game. Always align your held berry with the nature listed in the natures Pokemon chart above to ensure you aren't self-inflicting status conditions.

The Mathematical Impact: 10% is More Than You Think

To understand why the right nature is mandatory, let’s look at the math at Level 100. Consider a Pokémon with a base Attack stat of 130 (like Scizor).

  • With a nature that reduces Attack (like Modest): The stat will be roughly 264.
  • With a Neutral nature: The stat will be 296.
  • With a nature that boosts Attack (like Adamant): The stat will be 325.

Between a hindering nature and a beneficial nature, there is a 61-point difference. This gap is larger than the boost provided by most items and can be the difference between a move doing 45% damage (a 3-hit KO) and 55% damage (a 2-hit KO). In the world of competitive battling, the nature is often the first thing a player checks when evaluating a new team member.

Strategy: Choosing the Right Nature for the Right Role

Selecting a nature isn't always about boosting the highest stat; it's about optimizing the role the Pokémon plays on your team.

1. The Physical Sweeper

For Pokémon meant to deal high physical damage, the choice is usually between Adamant (+Atk, -SpAtk) and Jolly (+Spe, -SpAtk).

  • Choose Adamant if: Your Pokémon is already extremely fast (e.g., Regieleki) or relies on priority moves like Sucker Punch or Extreme Speed.
  • Choose Jolly if: Your Pokémon is in a crowded speed tier (Base 100-110). Being Jolly allows you to outspeed Adamant variants of the same Pokémon.

2. The Special Sweeper

Similarly, special attackers choose between Modest (+SpAtk, -Atk) and Timid (+Spe, -Atk).

  • Choose Modest if: You are using a Choice Scarf to boost speed via an item, or if the Pokémon is a "wall-breaker" meant to punch holes in the opponent's defense.
  • Choose Timid if: You need to maximize your chance of moving first against other fast special attackers.

3. The Dedicated Wall

Defensive Pokémon usually choose between Bold/Impish or Calm/Careful.

  • A common mistake is trying to balance stats (e.g., using a SpDef-boosting nature on a Pokémon with low SpDef). Generally, it is more effective to lean into a Pokémon's natural strengths. If a Pokémon has massive physical Defense, use a Bold or Impish nature to make it an impenetrable physical wall.

4. Trick Room Specialists

In Trick Room, the slowest Pokémon moves first. Therefore, you want a nature that decreases Speed.

  • Physical: Brave
  • Special: Quiet
  • Defensive: Relaxed or Sassy
  • Pro-tip: For maximum efficiency in Trick Room, players also hunt for "0 Speed IVs" to ensure their speed stat is as low as mathematically possible.

Modern Quality of Life: Nature Mints

In the past, if you caught a Legendary Pokémon with the wrong nature, it was a disaster. Since Generation VIII (Sword & Shield) and continuing through the 2026 meta, Nature Mints have solved this problem.

Mints allow you to change the stat effects of a nature without changing the nature itself. If you have a Bold Suicune but want it to be Timid, you can feed it a Timid Mint.

  • The Result: Its stats will now grow as if it were Timid (+Speed, -Attack).
  • The Catch: Its profile will still say "Bold." This means that for breeding purposes (passing down natures via Everstone) and flavor/berry purposes, it still counts as Bold. Only the combat stats are altered.

Breeding for Natures: The Everstone Method

For those who prefer traditional breeding, the Everstone is your best friend. If a Pokémon holds an Everstone while in the Daycare or Picnic, 100% of its offspring will inherit its nature. This is the most efficient way to mass-produce competitive-ready Pokémon without spending currency on Mints.

Furthermore, the Synchronize ability remains a staple for catching wild Pokémon. If your leading Pokémon has the Synchronize ability, there is a 100% chance (in modern versions) that wild encounters will share that nature. Keeping a box of "Synchronize Synchronizers" with various natures like Adamant, Modest, Jolly, and Timid is a hallmark of a prepared trainer.

Final Recommendations for 2026

As the meta evolves, we see more niche uses for natures like Naive and Hasty. These are particularly useful for "Mixed Attackers"—Pokémon that carry both physical and special moves to avoid being walled. By reducing a defensive stat instead of an attacking stat, you maintain maximum offensive pressure, though you become a "Glass Cannon" in the process.

When in doubt, refer back to the natures Pokemon chart and ask: "What is this Pokémon's job?" If the job is to survive, boost Defense or Special Defense. If the job is to sweep, boost Speed or its primary Attack stat. Never settle for a neutral nature, and always double-check your berry flavors before heading into a ranked ladder match. The 10% difference might look small on paper, but on the battlefield, it is the margin between victory and defeat.
