There is no single best nature for every Pokémon in Pokémon FireRed and LeafGreen. Choose according to the Pokémon’s battle role and moves: Adamant is a strong starting point for a physical attacker, Modest for a special attacker, and Jolly or Timid when Speed matters more than maximizing the attacking stat. Defensive and deliberately slow Pokémon may benefit from a different tradeoff.
How natures affect stats in FireRed and LeafGreen
Natures are a feature in these Generation III remakes. In general, a nature raises one stat by 10% and lowers another by 10%; HP is unaffected. Five natures are neutral because the increase and decrease apply to the same stat, leaving no net change.
Build the choice around the moves the Pokémon will actually use. A special attacker that rarely uses physical moves can often afford to lower Attack; a physical attacker can often afford to lower Special Attack. A Speed-boosting nature trades some offensive power for the chance to act sooner. That exchange is worthwhile when moving first matters to the role.
Quick nature guide by battle role
| Role | Nature | Stat change | When it can fit |
|---|---|---|---|
| Physical attacker | Adamant | +Attack, −Special Attack | When the set relies on physical moves and can spare Special Attack. |
| Fast physical attacker | Jolly | +Speed, −Special Attack | When acting sooner is more valuable than boosting Attack further. |
| Special attacker | Modest | +Special Attack, −Attack | When the set relies on special moves and can spare Attack. |
| Fast special attacker | Timid | +Speed, −Attack | When moving first matters more than increasing Special Attack. |
| Physical wall | Impish | +Defense, −Special Attack | When the Pokémon is meant to take physical hits and does not rely on Special Attack. |
| Special wall | Calm | +Special Defense, −Attack | When the Pokémon is meant to take special hits and does not rely on Attack. |
| Slow physical attacker | Brave | +Attack, −Speed | When the plan does not depend on moving first. |
| Slow special attacker | Quiet | +Special Attack, −Speed | When the plan does not depend on moving first. |
These are role-based starting points, not guaranteed best choices for every species, team, or moveset. Check a Pokémon’s Generation III moves and intended battle role before settling on a nature.

How to choose between two plausible natures
- Check the moveset. Decide whether its damage mainly comes from physical or special attacks, then prioritize the stat those moves use.
- Ask whether Speed changes the role. If moving first is important, consider Jolly for a physical attacker or Timid for a special attacker. If it is not, an offensive or defensive boost may be more useful.
- Consider what hits it is meant to take. A Pokémon expected to absorb physical damage may value Defense; one expected to absorb special damage may value Special Defense.
- Prefer a useful drawback. When possible, lower the stat the planned set rarely uses rather than choosing by the Pokémon’s type alone.
What if the nature is neutral?
Hardy, Docile, Bashful, Quirky, and Serious have no net stat effect. A Pokémon with one of these natures is still usable; it simply does not receive a positive stat tradeoff from its nature.

For a species-specific recommendation, state the assumed role and moveset. The same Pokémon may reasonably use different natures if one set attacks physically, another attacks specially, or one needs Speed while another is built to take hits. In other words, ask which nature best supports the way you plan to use it—not which nature is universally best for that species.
