Wattson (Japanese: テッセン Tessen) is the Gym Leader of Mauville City's Gym, known officially as the Mauville Gym. Trainers who defeat him receive the Dynamo Badge. He is a jolly old man who specializes in Electric-type Pokémon.

In the core series games

Wattson's title is "The cheerfully electrifying man!" The citizens of Mauville think of him as "eccentric," and one of his students affectionately referred to him as a "tough coot." He prefers to employ Electric-type Pokémon, and is a generally jovial man.

Wattson founded Mauville; in Generation III he once had a desire to convert Mauville in an expansion project, but abandoned that plan. Instead, he installed switch-controlled dynamos in his Gym that create doors of electricity. In the remakes, however, Wattson's conversion plans were realized.

Wattson was the Project Leader of the Sea Mauville project under Greater Mauville Holdings. Based on documents in Sea Mauville, Wattson ended up being involved in the closure of both New Mauville and Sea Mauville due to issues involving the environment and Pokémon. Prior to the closure of Sea Mauville, Wattson was under investigation by Dock for actions that Wattson took to close New Mauville.

In addition to the Dynamo Badge, Wattson gives out TM34 (Shock Wave), in Ruby, Sapphire, and Emerald. In Omega Ruby and Alpha Sapphire, he gives out TM72 (Volt Switch)

If the player returns to Mauville after getting SurfRSE or saving Hoenn from Primal GroudonOR/KyogreAS, Wattson will wait in Mauville City outside his Gym, asking the player to go to New Mauville on an errand for him. If the player completes the task, Wattson will give them TM24 (Thunderbolt) as a sign of his appreciation.

Wattson in the anime

Wattson debuted in Watt's with Wattson?. He manned the controls to his Gym's trap and laughed as Ash and his friends made their way through the facility. One of Wattson's tricks was a robotic Raikou that ended up overcharging Pikachu's electricity. As a result, Pikachu was able to completely wipe out Wattson's team on his own, using a series of supercharged Thunderbolts and an equally supercharged Thunder attack.

Disheartened by this humiliating loss, Wattson handed Ash the Dynamo Badge; left his Pokémon at the local Pokémon Center; and wandered off to his training spot, the New Mauville power plant, to clear his head. There, Wattson befriended an Electrike. Soon after, Team Rocket stole all of the Electric Pokémon from the power plant. Watt, Ash, and the others soon located Wattson and they confronted Team Rocket together. Wattson used his electric Raikou to distract Team Rocket, while Pikachu and Electrike helped free the wild Pokémon. Pikachu and Electrike then fought Team Rocket's Pokémon before sending them all blasting off. Ash explained that Pikachu had become supercharged from the Raikou mecha and tried to return the Dynamo Badge, but Wattson told him to keep it. Electrike decided to stay with Wattson, giving him a fresh start. Wattson then challenged Ash to a battle once his Electrike had grown a bit, and Ash accepted.

Wattson reappeared in Manectric Charge, where he saved most of the group's Pokémon from another Team Rocket scheme upon their return to Mauville City. The resulting battle caused Electrike to evolve into Manectric. Though they were on their way back to Petalburg City, Ash and his friends decided to take a break and have a battle. Wattson first refereed a match between Watt and his Ampharos, and May and her Skitty, with May emerging victorious. Next, Ash's Torkoal fought Manectric in a fierce match, which Manectric won.

He reappeared in a flashback in Whiscash and Ash.


Wattson is a jovial man with a contagious laugh, much like his game counterpart. He is also a practical joker at heart, and he has gone on to fill the Mauville Gym with traps to keep his challengers tense before their match begins. This extends into his battle strategy, and he uses surprise techniques like his Manectric's Charge to overcome his challenger's advances. Wattson takes a hands-on approach to raising his Pokémon.


This listing is of Wattson's Pokémon in the anime.

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.

Magnemite's known moves are Swift and Thunder Wave*.

It reappeared in a flashback in Whiscash and Ash.

Magneton's only known move is Zap Cannon.

Electrike → Manectric
Main article: Wattson's Manectric

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.

Wattson in Pokémon Adventures


Ruby & Sapphire arc

When Sapphire arrives at Mauville City to challenge her third Gym, she is attacked by one of the Trick Master's machines. When she is captured by it, Wattson and the Trick Master come out of hiding to celebrate their victory, only to realize their mistake. Wattson apologizes for the trouble he caused Sapphire and explained that he and the Trick Master were aiming to capture a wild trouble-making Donphan in the area. When Sapphire wondered if the trap-door she fell into earlier was another one of their gadgets, Wattson realizes that Sapphire had accidentally found the entrance to New Mauville. They attempt to open the entrance again, only for a group of children aiming to challenge Wattson arrive. Wattson easily defeats that children, but awards them Gym Badges anyway. This angers Sapphire, but Wattson explains that he does not really care about the results and enjoys giving Badges if his opponents do their best. He offers a Badge to Sapphire for finding the entrance to New Mauville, but she angrily rejects it on the pretense that wants to earn it in a battle.

Sapphire smacks the Badge away from Wattson, which lands on the Donphan and provokes it into chasing after the three. Wattson, Trick Master, Sapphire, and Donphan all end up crashing into New Mauville. Wattson ends up separated from the others and gets attacked by the New Mauville generator. The generator defeats and captures Wattson and continuously drains his Pokémon's electricity. Sapphire works together with Wattson's Electrike and Donphan to stop the generator and free Wattson from its grip. When the generator is defeated, they find that New Mauville was created by the Trick Master's ancestor as a playground for children. They decide to renovate the place so that the children of Mauville City can have a place to play in. Wattson thanks Sapphire for her help and later awards her with the Dynamo Badge.

Later, Wattson and the other Gym Leaders are called by Flannery to meet in Fortree City. They have a discussion on Team Magma and Team Aqua about whether or not one of the teams is evil and the other is good. Wattson sides with Team Magma, as their goal is to expand the landmass meant that Mauville City could get more land for the children to play in.

When Groudon and Kyogre are awakened, they begin causing droughts and downpours throughout Hoenn. Wattson and Flannery are sent to the rain-plagued areas to face Kyogre in battle. Despite their best efforts, Kyogre proves to be too powerful for any of their attacks to damage it. They are later assisted by Winona, who also participates in the battle to stop Kyogre, but all three are interrupted by the Subleaders of the Sea Scheme of Team Aqua, Amber, Shelly, and Matt. The Subleaders all face one of the Gym Leaders to make sure they can't stop Kyogre from advancing any further.

Wattson in the thirteenth chapter

Wattson faces Amber in battle and easily defeats his single Water-type Pokémon, leaving his opponent without anything else to use. Shelly assists her ally by giving Amber her Nincada to use in battle. Wattson continues to have an easy time against his opponent, but Amber reveals he was stalling so that Nincada could evolve into Ninjask. With its newfound speed, Ninjask gains an advantage over Wattson's Manectric, forcing Wattson to sacrifice his Pokémon to knock it out. Wattson gloats over his victory since he still has more Pokémon to battle with, but he is struck from behind and knocked into the sea. As he sinks, Amber reveals that when his Nincada evolved, it also created a Shedinja that attacked Wattson when he was defenseless. Wattson is later rescued by Sapphire's Lorry, which brought him back to the surface using Dive and Water Spout.

After both Team Magma and Team Aqua are defeated and Groudon and Kyogre have returned to their deep slumber, Wattson celebrated the victory with his allies and thanked Sapphire and Ruby for their assistance in the battle.

Omega Ruby & Alpha Sapphire arc

Wattson, along with various people from around Hoenn, is called to Sootopolis City to assist in stopping Grand Meteor Delta, a giant meteoroid threatening to destroy the planet. When the plan to attack Grand Meteor Delta starts, Wattson and the others have their Pokémon attack the meteoroid at the same time. This, combined with the might of Mega Rayquaza, successfully shatters Grand Meteor Delta into pieces.


Wattson is a joke-loving Gym Leader who is friends with the Trick Master.

Wattson in Pokémon Pocket Monsters

Wattson appeared in Christmas Night Is Battle Night!.

Earlier, he told his Electrike to get food for him. Wattson revealed this to Red after Electrike led the group to him when it stole cake from Red. Wattson then gave out a business card. He hid inside a trash can and leaped out in order to surprise someone else and gave out the same card that was given to Red. Clefairy didn't like what Wattson was doing and Electrike growled at Clefairy for disagreeing. Later, Wattson took the group to a Christmas tree shop and goes inside. While inside, he opened the door to his office which turned out to be empty and beaten up. Feeling sorry for what happened, Clefairy decided to deliver presents in order to cheer Wattson up again. Dragging a sleigh from house to house, Wattson and Clefairy went inside people's houses from the chimney and delivered the presents. When they got back, Wattson and the group discovered that the presents were from the items in the Christmas tree shop and Wattson chases Clefairy for stealing his stuff.



In the TCG

In the Pokémon Trading Card Game, one of Gym Badge's illustrations features Wattson and the Dynamo Badge.


  • Like Lt. Surge is in Kanto, Wattson is the third Gym Leader encountered on a journey, and is similarly enamored with trap doors and Electric-type Pokémon.
  • Wattson is the first Gym Leader who isn't one of Ash's friends whom Ash has battled after earning his Badge.
  • Wattson is the only Gym Leader outside of the original series whom Ash has defeated in their debut episode.
  • Wattson is the only Gym Leader in Ruby and Sapphire without a single Pokémon introduced in Generation III. This was changed in Emerald when Electrike and Manectric were added to his initial roster.
    • Additionally, this makes Wattson the only Gym Leader outside of Johto who doesn't have a Pokémon introduced in the generation he first appears as a Gym Leader.
  • In the Norwegian dub of the anime, Wattson has a slight Danish accent.
