Iron Boulder is the future Paradox form of Terrakion, bearing a Rock/Psychic typing instead of Rock/Fighting. If you want to optimize Iron Boulder's power in battle, you'll need to pick the right nature for it in Pokémon Scarlet and Violet.
What are the best natures for Iron Boulder in Pokémon Scarlet & Violet?
The best natures for Iron Boulder in Pokémon Scarlet and Violet are either of the following:
- Jolly (+Speed, -Sp. Attack)
- Careful (+Sp. Defense, -Sp. Attack)
Iron Boulder has great offensive potential, thanks to its high Speed and Attack stats. However, its typing leaves it with a whopping seven weaknesses, meaning it's vulnerable to super-effective attacks. By bolstering its Speed stat with the Jolly nature, you can ensure that Iron Boulder will outspeed most of its opponents and get the first strike in.
If you're looking for a more defensive core on your Pokémon team, Iron Boulder also has high Special Defense, making it perfect for walling opponents like Iron Moth. While you'll sacrifice some offensive potential, you'll increase Iron Boulder's survivability and make sure it gets those hard-hitting moves out.
How to choose the best nature in Pokémon Scarlet & Violet
Most natures in Pokémon boost one stat while reducing another; to choose the best one, you'll need to identify your Pokémon's strengths and weaknesses. For example, Iron Boulder's lowest stat is its Special Attack, so choosing natures that lower it won't cost you anything in the long run. You should also study your Pokémon's movepool; Pokémon like Iron Boulder that learn a lot of physical moves should have natures that increase their Attack.
