What does the Relaxed nature do in Pokemon?
Relaxed gives your Pokemon 10% more Defense at the cost of Speed. That tradeoff works best when the lowered stat isn't part of your moveset. Pokemon with Relaxed nature prefer Sour flavor and dislike Sweet.
What are the best Relaxed nature Pokemon?
Competitively, Tyranitar, Slowbro, Torkoal, and Jirachi run Relaxed most often. The +Defense boost complements their role, and the -Speed penalty barely affects their game plan.
Is Relaxed a good nature for competitive Pokemon?
For the right Pokemon, Relaxed is one of the best natures you can pick. The -Speed drop actually helps under Trick Room, where slower Pokemon move first. Just don't slap it on something that uses Speed-based moves.
How do I get a Relaxed nature Pokemon?
Breeding with an Everstone is the most reliable approach since Gen 5. The parent holding it passes its nature to every offspring. Synchronize works for wild catches. And if you already have the Pokemon, a Relaxed Mint from the Battle Tower changes the stat effects to Relaxed.
Should I use Relaxed or Bold?
Short answer: Relaxed for Trick Room wall, Bold for standard wall. There's no universal best. Check your Pokemon's base stats and common threats in the format you're playing to decide which tradeoff is better.
