Mauville Gym is an electric-type gym led by Leader Wattson. You can navigate the gym's puzzle quite easily by stepping on the switches that move around electrical barriers. Wattson's Pokémon all have a weakness to Ground type, so Geodude is a good option; if you chose Torchic as your starter it may be a good option as well, since ground types are hard to come by. Be prepared to heal from paralysis and watch out for the Super Potions that Wattson will use to heal just before you thought you'd beat him.

Wattson will give you the Dynamo Badge and TM72 - Volt Switch once you've beat him. The Dynamo Badge allows you to use Rock Smash outside of battle and forces all Pokémon up to Level 40 to obey you.
