Mauville City Pokémon Gym Leader: Wattson The cheerfully electrifying man!
Mauville City Pokémon Gym Leader: Wattson The cheerfully electrifying man!
Before entering the Mauville Gym, the player is forced to battle Wally in front of it.
In generation III, the Gym is filled with electrical barriers designed by Wattson himself. The barriers can be turned on and off by stepping onto switches across the floor. After the Gym Leader has been defeated, the barriers will be turned off permanently.
In generation VI, the Gym's electrical barriers now come in blue and red varieties, with color-coded switches. Stepping on a switch shifts the direction the like-colored barriers project from vertical to horizontal and vice-versa. The Gym has also been divided into two different floors. Just like in Generation III, the barriers are turned off once the Gym Leader has been beaten.
Trainers with a PokéNav by their names will be registered in the Trainer's Eyes or Match Call function after the first battle, and may have a rematch with the player with higher-level Pokémon.

The Mauville Gym first appeared in Watt's with Wattson?. Ash and his friends reached the Gym, where the young Pokémon Trainer entered it in order to challenged Wattson for a Gym battle. However, the group quickly got lost inside the building, as the Gym had many traps, like falling into a whirlpool. After going through all the traps, Ash challenged Wattson and won flawlessly, stunning the Leader and making him question his abilities. Ash eventually realized that Pikachu had accidentally been supercharged by one of Wattson's Raikou robots. After realizing what happened, Wattson told Ash to keep the Badge and not to worry about challenging him again.
When Ash and the others returned to Mauville City in Manectric Charge, Ash decided to challenge Wattson again, this time with his newly captured Torkoal. This time, Wattson defeated Ash with his newly evolved Manectric. May also had a battle against Wattson's Gym assistant Watt here and won.
Pokémon used in the Gym
Magnemite
Magnemite was the first Pokémon used by Wattson in his Gym battle against Ash. Due to Pikachu being powered-up by the exploding mecha-Raikou, it was defeated with only a single Thunderbolt.
Magnemite has worked with Wattson for a number of years, during which Wattson and Magnemite overcame Magnemite's struggle to master Thunder Wave.
Magneton was the final Pokémon used Wattson during the Gym battle. By this point in the match, both Wattson and Magneton were determined to defeat Ash, but Magneton couldn't stand up to Pikachu's super-charged Thunder and was also knocked out in a single hit.
Manectric first appeared as an Electrike after Wattson's defeat by Ash. After cheering Wattson up, it sent Team Rocket blasting off together with Ash's Pikachu. After this, it stayed with Wattson.
It was seen again when the gang returned to Mauville City. Electrike evolved into Manectric after defeating Team Rocket. Ash decided to challenge Wattson and Manectric to a training match with his Torkoal. After a fierce battle, Manectric emerged victorious.
