NAUGHTY FAQs
What does the Naughty nature do in Pokemon?
Naughty raises Attack by 10% and lowers Sp. Defense by 10%. At level 100 with full investment, that's roughly a 30-point swing on the boosted stat. Pokemon with Naughty nature prefer Spicy flavor and dislike Bitter.
What are the best Naughty nature Pokemon?
Top Naughty users include Registeel, Barboach, Seaking, and Shiftry. They benefit from the Attack boost because their main damage comes from that stat. The Sp. Defense drop doesn't hurt them since they don't rely on it.
Is Naughty a good nature for competitive Pokemon?
Naughty 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. Defense in their moveset.
How do I get a Naughty nature Pokemon?
Synchronize is the fastest method. Lead with a Pokemon that has Synchronize and Naughty nature, and wild encounters match it (Gen 3+). Breeding works too: give the Naughty parent an Everstone and all offspring inherit the nature. Nature Mints (Gen 8+) let you change the stat effect to Naughty without rebreeding.
Should I use Naughty or Adamant?
Naughty prioritizes mixed offense, while Adamant goes for dedicated physical. Pick Naughty when your Pokemon's role depends on the stat it boosts. Go with Adamant when dedicated physical matters more for your team.
