Here's what you need to know about natures:
* Natures are random: When you catch a Pokemon or hatch an egg, it will have a randomly assigned nature.
* Natures affect two stats: Each nature boosts one stat and lowers another. For example, the Brave nature boosts Attack and lowers Special Attack.
* Bravery boosts Attack and lowers Special Attack: So, if you want a Pokemon with a higher Attack stat, you'll want to find one with the Brave nature.
How to find a Pokemon with the Brave nature:
* Catch and release: The easiest way to find a Pokemon with the Brave nature is to catch and release Pokemon until you find one with the desired nature.
* Breeding: You can also breed Pokemon to try and get a desired nature. However, this is a more time-consuming process.
* Nature Mints: In later Pokemon games, you can use Nature Mints to change a Pokemon's nature. However, these are not available in Pokemon Black.
Important note: Bravery is not the only way to increase a Pokemon's Attack stat. You can also use:
* EV training: EV training involves giving your Pokemon certain items to boost their stats, like a Power Weight to boost Attack.
* Leveling up: As your Pokemon levels up, its stats will naturally increase.
Remember, choosing the right nature is important for maximizing your Pokemon's potential, but it's not the only factor to consider.
