Welcome to Rustboro City, home of the first Gym Leader, Roxanne! Her gym specializes in Rock-type Pokémon. Before challenging her, make sure your Pokémon are well-trained, ideally around Level 12-15. Grass and Water-type Pokémon have a significant advantage here. If you chose Treecko or Mudkip, you're in a good position. If you chose Torchic, consider catching a Lotad (Sapphire) or Nuzleaf (Ruby) on Route 102/104, or a Marill on Route 102. Geodude and Nosepass are Roxanne's main threats. Nosepass has high Defense, so special attacks or super-effective physical attacks are best. Defeating Roxanne will earn you the Stone Badge, allowing you to use HM01 Cut outside of battle, and TM39 Rock Tomb.
