Mauville is a large city, located in-between four different routes. The roads of the town stretch north toRoute 111, west toRoute 117 andVerdanturf Town, east to a beach onRoute 118, and south toRoute 110.
Wattson is theGym Leader and founder of Mauville. InGeneration III, he originally had plans to do a complete overhaul of the town, but abandoned them. InGeneration VI, Wattson instead managed to redevelop it, modeling the design on that ofLumiose City ofKalos. Due to this, its layout has changed dramatically, becoming a mostly-indoor city with various shops and three floors. The redevelopment of Mauville is the only successful project ofGreater Mauville Holdings.
Located in the north-west of the city, the Mauville Gym specializes inElectric-type Pokémon. Wattson, the Gym leader hands out the Dynamo Badge to players who defeat him. The Gym contains electric dividers that turn on or off when different switches are stepped on.
Located in the east of the city, a store known asRydel's Cycles. It is very conveniently located for the owner and customers alike, as theSeaside Cycling Road runs onRoute 110, just to the south.Rydel sellsAcro Bikes andMach Bikes. However, he will give theplayer a bike for free after he finds out that the player has come all the way fromLittleroot Town with justRunning Shoes. The player may exchange their bike with Rydel for the other bike.
InGeneration VI, after theDelta Episode, the player has the opportunity to carry both bikes at the same time. After advertising the bikes to certain NPCs, the player will receive the counterpart bike of the one they are currently using as thanks for their continued advertisement of the Rydel brand. The NPCs are located:
Located in the south west of the city, theMauville Game Corner can be found. InGeneration III, it is a tourist attraction where people can gamble coins on slots or roulette. This game corner houses two roulette wheels and sixteen slot machines. ACoin Case is needed to play at the game corner, which can also be found in one of the houses at Mauville City, in exchange forHarbor Mail.
InGeneration VI, the Game Corner is closed, with the owner stating that he had to close it for "reasons you don't need to know".On the closed door, a notice reads:
"Thank you for your support over the years. Good game!"
In the Mauville Pokémon Center, a quintet of characters known as the old guys can be found. InGeneration III, they will all appear in the Pokémon Center depending on the player'sTrainer ID number, though a different one can appear if they mix records with another player that has a different man in their game.
InGeneration VI, the Old guys will give the player variousO-Powers. Only Giddy initially appears in the Pokémon Center, and after being interacted with twice, he will leave. Other old guys will only appear or give the player their second set of O-Powers after the player has reached specific points in the storyline. If one of the men leaves, the next will not appear until the player has reached the point in the storyline where they can receive the next O-Power; if the player obtains the first O-Power from one old guy but is not yet far enough in the game to obtain the second from him, the current old guy will remain in the Pokémon Center.
After the Storyteller has left the Pokémon Center for their shared apartment in Mauville Hills (Apartment 3), when the player visits all five in their apartment, the Storyteller will mention that they are looking for someone to pass their powers to; the player tells him about the powerless man living across the hall, at which point the Storyteller requests that the player lead the powerless man to them. If the player does so, they will each give him their power (disappearing after doing so), turning the powerless man into Mr. Bonding. Mr. Bonding will give the player the final O-Power, Hatching Power, and leave.
InPokémon Ruby and Sapphire, this character is unidentified. InPokémon Emerald only, he is known as Rock Smash Guy (Japanese: いわくだきオヤジRock Smash Old Man), but he prefers to be called Rock Smash Dude (Japanese: いわくだきにいさんRock Smash Young Man).
In the English version of Pokémon Emerald, there is also a non-player character onRoute 111 who claims that this HM is obtained from his uncle. This also applies to the German, French, Italian, and Spanish versions, which were translated from English. However, in the Japanese version, he simply refers to the Rock Smash Guy using the word 「オヤジ」, which can mean either "old man" or "father".
Located in the north east of the city, the TV station that runs the news on theBuzzNav can be found. The player can sit at the news desk, but this doesn't put them on the BuzzNav news.
Located in the south east of the city, the Mauville Food Court allows the player to place an order for food at one of the three counters. After paying, the player is given an amount of turns to wait for their meal. Taking a seat, the player is then challenged to battle by a gauntlet of Trainers trying to take their seat away.

Inver uses a different pool of Pokémon compared to the ones he used inX and Y, and they start atlevel 20 as opposed to level 55. Inver hasmany preset Pokémon, but only chooses a random three during the battle. In addition, his Pokémon'sAbilities may vary, even potentially having their Hidden Abilities.
