After training on Route 117, I decided to head back to Route 110 and do some training there. I also captured some wild Pokemon while I was in the area, as I wanted to fill up my Pokedex some more. After training, I healed my Pokemon at the Mauville City Pokemon Center. I bought a few Potions at the Poke Mart, and then I entered the Mauville City Gym. I faced off against the trainers inside and I solved the Gym puzzle quite easily. After healing my Pokemon again, I challenged Gym Leader Wattson to a battle. He sent out his Magnemite first, and I used a Geodude that I had captured at Granite Cave. I defeated Magnemite with Magnitude, and then I used my Combusken against Wattson's Voltorb. I defeated it with Double Kick, then I used my Makuhita against Magneton. I defeated it with a few Arm Thrust attacks, and I won the Dynamo Badge and the Shock Wave TM.
