How to Get
SynchronizeLead with a Calm Pokemon that has the Synchronize ability. Wild Pokemon will match its nature. (Gen 3+)
BreedingGive the parent with Calm nature an Everstone. The offspring will inherit it. (100% since Gen 5)
Nature MintUse a Calm Mint to change stat effects to Calm. The original nature name stays but stats change. (Gen 8+)
Other +Sp. Defense Natures
Careful (-Sp. Attack)Gentle (-Defense)Sassy (-Speed)
What does the Calm nature do in Pokemon?
Calm raises Sp. Defense by 10% and lowers Attack by 10%. At level 100 with full investment, that's roughly a 30-point swing on the boosted stat. Pokemon with Calm nature prefer Bitter flavor and dislike Spicy.
What are the best Calm nature Pokemon?
Top Calm users include Dialga, Palkia, Clefable, and Heatran. They benefit from the Sp. Defense boost because their main damage comes from that stat. The Attack drop doesn't hurt them since they don't rely on it.
Is Calm a good nature for competitive Pokemon?
Calm is a strong competitive nature. It fills a solid niche for defensive builds. The key is matching it to Pokemon that don't need Attack in their moveset.
How do I get a Calm nature Pokemon?
Synchronize is the fastest method. Lead with a Pokemon that has Synchronize and Calm nature, and wild encounters match it (Gen 3+). Breeding works too: give the Calm parent an Everstone and all offspring inherit the nature. Nature Mints (Gen 8+) let you change the stat effect to Calm without rebreeding.
Should I use Calm or Careful?
Calm prioritizes special wall utility, while Careful goes for physical wall utility. Pick Calm when your Pokemon's role depends on the stat it boosts. Go with Careful when physical wall utility matters more for your team.
