How to Get
SynchronizeLead with a Bold Pokemon that has the Synchronize ability. Wild Pokemon will match its nature. (Gen 3+)
BreedingGive the parent with Bold nature an Everstone. The offspring will inherit it. (100% since Gen 5)
Nature MintUse a Bold Mint to change stat effects to Bold. The original nature name stays but stats change. (Gen 8+)
Other +Defense Natures
What does the Bold nature do in Pokemon?
Bold raises 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 Bold nature prefer Sour flavor and dislike Spicy.
What are the best Bold nature Pokemon?
Top Bold users include Lunala, Lugia, Mesprit, and Tornadus. They benefit from the 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 Bold a good nature for competitive Pokemon?
Bold 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 Bold nature Pokemon?
Synchronize is the fastest method. Lead with a Pokemon that has Synchronize and Bold nature, and wild encounters match it (Gen 3+). Breeding works too: give the Bold parent an Everstone and all offspring inherit the nature. Nature Mints (Gen 8+) let you change the stat effect to Bold without rebreeding.
Should I use Bold or Impish?
Bold prioritizes special defense utility, while Impish goes for physical defense utility. Pick Bold when your Pokemon's role depends on the stat it boosts. Go with Impish when physical defense utility matters more for your team.
