New Mauville
ニューキンセツ New Kinsetsu
"Wild Missingno. appeared!"
Map description:
Though it was planned to be a subterranean city extending 69 floors underground, this project died in development.
New Mauville (Japanese: ニューキンセツNew Kinsetsu) is a power plant located underneath Mauville City in Hoenn. Due to its unique location, the complex can only be reached by Surfing from Route 110 east under the Seaside Cycling Road to a small island east of the overhead path.
In Generation VI, New Mauville has a strong magnetic field that causes Magneton and Nosepass to evolve into Magnezone and Probopass, respectively, when leveled up here.
After completing a certain storyline event (which event depends on the game), Wattson stands outside in Mauville City. Upon talking to him, Wattson requests that the player goes to investigate New Mauville. After performing the requested action, Wattson rewards the player with TM24 (Thunderbolt).
In Pokémon Ruby, Sapphire, and Emerald, Wattson stands at the intersection of Route 110 and Route 118 after the player earns the Balance Badge. He requests that the player shut down the generator in New Mauville as a safety precaution. To allow the player access to the underground plant, Wattson gives the player the Basement Key, which opens the door to New Mauville permanently. Wattson will remain in the center of Mauville City until the player returns, giving the player TM24 (Thunderbolt) as a reward after they shut off the generator.
In Pokémon Omega Ruby and Alpha Sapphire, after defeating or capturing GroudonOR/KyogreAS, Wattson stands in front of the Square Tower in the outdoor area on 1F of Mauville City, where he will tell the player there is an issue and New Mauville, and requests that the player visit him in his Mauville Hills apartment (granting the player access to the Mauville Hills elevator at the same time). In his apartment, he requests that the player press the button on the computer at the back of the facility; he then takes a photo of the player character's eyes and submits the picture to the New Mauville's gate's eye recognition software as authorized personnel, allowing the player to open the gate anytime. If the player visits Wattson in his Mauville Hills apartment after pressing the button, he rewards the player with TM24 (Thunderbolt).
Geography
In Ruby, Sapphire, and Emerald, the facility is a labyrinth of doors. There are green and blue doors, which only open when the corresponding button color is pressed; these buttons are found on the ground throughout the facility. However, the two types of doors cannot be open simultaneously.
In Omega Ruby and Alpha Sapphire, New Mauville instead extends 69 floors underground, but the player can only access the first floor, and only two rooms of that floor. There is a front room, which is located at the facility's entrance, and the generator room, which is accessed through the open door in the northwest of the first room.
Throughout the facility, there are some Voltorb that look like item balls.

New Mauville appeared in the episode Watt's with Wattson?. New Mauville is located on an island just off the coast of Mauville City. The Power Plant had long been abandoned and is now a refuge for Electric-typePokémon like Voltorb, Magnemite, and Magneton. New Mauville is Wattson's favorite place and he trains there often. He also catches an Electrike here. Team Rocket tries to take over the power plant and make it their secret Hoenn base, but are stopped by Ash, his friends, and Wattson.

New Mauville in Pokémon Adventures
In the Pokémon Adventures manga
In Pokémon Adventures, New Mauville was designed by an ancestor of the Trick Master to combat the foreseen overpopulation of children in Mauville City, which was already starting to happen by the Hoenn saga. While its location was not known, Sapphire accidentally came across the entrance and entered with Wattson and the Trick Master. After saving Wattson from the power generator, the power was turned on to reveal an enormous playground designed for children. It was quickly put into use.
