Watt's With Wattson? (Japanese: キンセツジム！テッセンの電撃バトル！！ Mauville Gym! Wattson's Electric Shock Battle!) is the 40th episode of Pokémon: Advanced.
The time has come, once again. Ash was super psyched to have another Gym Battle. This time, it was with the elderly, yet hilarious, Wattson. The battle was short as Ash's Pikachu took out Wattson's entire team with just one hit each. Devastated, Wattson gave Ash the Dynamo Badge. Will Wattson recover from this, and what has happened to Pikachu?
The gang arrived to Mauville City where Ash is going to battle for his third badge. As Ash opens the door, it crashes down, but it turns into an escalator, leading them into the Gym itself. The Gym Leader has turned the power on, making him amused, even if his assistant does not. The gang crosses the water and encounter a mechanical Raikou. However, Ash orders Pikachu to use Thunderbolt and Iron Tail. The Raikou explodes, revealing to be fake.
The Gym Leader exits the room and introduces himself and his assistant. Ash demands a battle, to which the Gym Leader agrees, laughing. Team Rocket has arrived to an abandoned power plant and they'll make it as the base in Hoenn. As they enter, they quickly leave, as many Voltorb, Magnemite and Magneton were inside. Jessie and James find it impossible to fight them so they walk away, but Meowth persuades them that their boss would like to have them for electricity his devices need.
The Gym Leader reveals that he will use his Voltorb, Magnemite and Magneton against Ash. Pikachu goes first to battle, so Wattson uses Magnemite. Magnemite attacks with Swift, but Pikachu dodges. Wattson taunts Ash, as his Pokémon are resistant to Electric-type attacks. Pikachu attacks with Thunderbolt, defeating Magnemite. Wattson sends Voltorb and has Voltorb use Screech, but Pikachu uses Thunderbolt, defeating it and surprising Wattson and his friends.
Magneton uses Zap Cannon, so Pikachu counterattacks with Thunder, defeating Magneton and amazing the audience. Wattson gives Ash the Dynamo badge and goes away. Ash notices that Pikachu looks pretty bad. Wattson gives Joy the Pokémon to take care for and leaves with a suitcase. The gang arrives with Pikachu, as it seems sick. Wattson is troubled, as he lost his battle to Pikachu - by just 3 hits. He notices that an Electrike has approached him. Wattson gives it some food.
At the Center, Joy discovers that Pikachu has more electricity than normal - Ash recalls that it fought the mechanical Raikou, which must have powered Pikachu up. Pikachu recovers. Wattson's assistant arrives with a note that he abandoned his career. However, Nurse Joy thinks he might be in the abandoned power plant, so everyone has to go there to tell him the truth. Meanwhile, Wattson befriends an Electrike and it shows that it has potential to use Thunder Wave. Wattson spots a machine with Team Rocket heading to the power plant.
They capture the Pokémon and the Pokémon use electricity, but with no effort. The gang arrives to explain, though Team Rocket captures Pikachu and Electrike. Team Rocket releases a net to keep everyone from attacking while they go off. Wattson has an idea - a mechanical Raikou intercepts Team Rocket, stopping them. Brock sends Forretress and it uses Rapid Spin, with May sending Torchic to use Ember.
Pikachu uses Iron Tail, Electrike bites and Magneton tackles the cage. James sends Cacnea to use Pin Missile, while Jessie sends Seviper to use Poison Tail on the Raikou. As they attack, the machine collapses, revealing it to be fake. Pikachu and Electrike destroy the cage, setting everyone free. Seviper uses Poison Tail and Cacnea uses Pin Missile, but Pikachu dodges both attacks. Pikachu uses Thunderbolt and Quick Attack, knocking both Pokémon out.
Jessie sends her Dustox and it uses Whirlwind, moving Pikachu away. Dustox uses Psi Beam, though Electrike uses Thunder Wave, negating the attack. Pikachu uses Thunderbolt, blasting Team Rocket away. Ash praises Pikachu for saving everyone, but Pikachu shows that Electrike helped as well. Ash represents Wattson his badge, as Pikachu was very powerful when it battled Wattson's Pokémon.
Wattson refuses, as he saw Pikachu rescuing all the Pokémon, since Ash trained it very well. Ash is happy knowing that the badge he caught was just. Wattson returns to the Gym, as he needs to train Electrike. His assistant is happy as Wattson is returning to be the Gym Leader again.
