Adamant vs Jolly
Choose Adamant
+Attack / -Sp. Attack
- Pokemon with priority moves (Extreme Speed, Aqua Jet, Sucker Punch)
- Dragon Dance or other speed-boosting move users
- Pokemon with base 130+ Speed that already outspeed threats
- Choice Scarf holders that compensate for lower Speed
Choose Jolly
+Speed / -Sp. Attack
- Pokemon in the base 80-110 Speed tier where one point decides matchups
- Pure sweepers without priority or speed-boosting moves
- Pokemon that need to outspeed a specific threat to function
How to Get
SynchronizeLead with a Adamant Pokemon that has the Synchronize ability. Wild Pokemon will match its nature. (Gen 3+)
BreedingGive the parent with Adamant nature an Everstone. The offspring will inherit it. (100% since Gen 5)
Nature MintUse an Adamant Mint to change stat effects to Adamant. The original nature name stays but stats change. (Gen 8+)
Other +Attack Natures
What does the Adamant nature do in Pokemon?
Adamant raises Attack by 10% and lowers Sp. Attack by 10%. At level 100 with full investment, that's roughly a 30-point swing on the boosted stat. Pokemon with Adamant nature prefer Spicy flavor and dislike Dry.
What are the best Adamant nature Pokemon?
Top Adamant users include Dragonite, Arceus, Ho-Oh, and Tyranitar. They benefit from the Attack boost because their main damage comes from that stat. The Sp. Attack drop doesn't hurt them since they don't rely on it.
Is Adamant a good nature for competitive Pokemon?
Adamant is a strong competitive nature. It's one of the most-used natures in competitive formats. The key is matching it to Pokemon that don't need Sp. Attack in their moveset.
How do I get an Adamant nature Pokemon?
Synchronize is the fastest method. Lead with a Pokemon that has Synchronize and Adamant nature, and wild encounters match it (Gen 3+). Breeding works too: give the Adamant parent an Everstone and all offspring inherit the nature. Nature Mints (Gen 8+) let you change the stat effect to Adamant without rebreeding.
Should I use Adamant or Jolly?
Adamant prioritizes power, while Jolly goes for speed. Pick Adamant when your Pokemon's role depends on the stat it boosts. Go with Jolly when speed matters more for your team.
