HARDY NATURE CALCULATOR
Natures weren't part of the series until Generation III (Ruby & Sapphire), so Red & Blue doesn't have them. Every stat is calculated from base stats, IVs (called DVs back then), and Stat Experience alone. If you're looking for the Hardy nature's stat effect, switch the game filter above to any Gen III or later title. That said, the concept still helps with planning teams for remakes like FireRed & LeafGreen or HeartGold & SoulSilver, where natures do apply.
Best Natures for Physical Attackers
Hardy doesn't boost or lower any stat. There's almost no reason to keep it in competitive play. Grab a Nature Mint and switch to something that gives your Pokemon an edge. Natures don't exist in Red & Blue. You'll need a Gen 3+ title to breed for a specific nature.
Hardy is a neutral nature with no stat change. For physical attackers, use Adamant or Jolly instead.
Adamant
+Attack/-Sp. Attack
Maximizes physical damage output
Jolly
+Speed/-Sp. Attack
Outspeed threats while hitting physically

HARDY FAQs
What does the Hardy nature do in Pokemon?
Hardy is a neutral nature. It doesn't raise or lower any stat, so your Pokemon's stats stay at their base values. In competitive terms, it's the same as having no nature effect at all.
Is Hardy nature good?
How do I get a Hardy nature Pokemon?
Three ways: (1) Breed with an Everstone on a Hardy parent. (2) Lead with a Synchronize Pokemon that has Hardy. (3) Just catch anything. There's a 1/25 chance it already has Hardy. But seriously, you probably want to change it.
When should you use a neutral nature?
Almost never. The only edge case is a Pokemon that uses physical moves, special moves, and needs every defensive stat and Speed. That Pokemon doesn't really exist in competitive. Even mixed attackers prefer Naive, Hasty, or another nature that at least boosts Speed.
