Mauville City Gym – Wattson
Right off the bat, all of Wattson’s Pokemon team are Electric type so don’t bring anything of the Water or Flying type up against him. If you do, a bad time will be waiting in your future. Against his first two Pokemon a fire type Pokemon will help as they are strong against electric and steel. The final member however is pure electric death so bring along a ground type to really cause him some issues. It’s likely you won’t have any ground type Pokemon right now in your journey through Pokemon Omega Ruby & Alpha Sapphire but there are some out there to be found. Nincada on Route 116 is a ground type and so is Geodude of the Granite Cave. Out of the two, get a Geodude and take the fight to Wattson.
Wattson’s Pokemon; a level 19 Magnemite, level 21 Magneton, and level 19 Voltorb, are all equipped with the same ability. This ability is Volt Switch. It allows them to deal damage to your Pokemon and then jump back into its respective Pokeball before calling forth another. Since they are all electric type attackers, expect an unhealthy amount of paralysis to land on anything that isn’t a ground type. If you are using any Pokemon that aren’t of this type, give them a Cheri Berry to hold or stock up on Paralyze Heals.
Gather up whatever ground type attacks you can muster so far in Pokemon Omega Ruby & Alpha Sapphire and settle in for a possibly aggravating battle as there aren’t many Pokemon at this stage in the game with the power to wipe the floor with Wattson’s electric family. Like Brawly before him, Wattson carries a Super Potion so if you don’t wipe out one of those crackling critters outright, expect it to be healed next turn.
Defeating Wattson and his Mauville Gym trainers nets you the TM for Volt Switch which you’ve likely already seen in action. You’ll also obtain a Dynamo Badge which unlocks new items to purchase, the ability to use Rock Smash outside of battle and dominion over all Pokemon under level 40.
