Manectric first appeared as an Electrike in Watt's with Wattson?. At the time, Wattson was in complete shock after Ash's Pikachu defeated his three Pokémon in quick succession, and he had left for New Mauville to clear his head. On the island, Electrike approached him, which cheered him up. With Electrike around, Wattson forgot about the loss completely and fed the Electric-type some Pokémon food.
As the pair played, Team Rocket arrived in their vacuum car to steal the power plant's wild Pokémon. Wattson confronted the trio, though Electrike and Ash's Pikachu were also captured. When Team Rocket became distracted by the robot Raikou Wattson uses at his Gym, it gave Electrike the chance to break out of the cage with Pikachu's assistance. Electrike managed to do so with its Bite attack and reunited with Wattson. It used Thunder Wave to temporarily stun Jessie's Dustox, while Pikachu sent Team Rocket blasting off. Afterwards, Electrike decided that it wanted to stay with Wattson, who added it to his team. Wattson then said his goodbyes to Ash and his friends, promising to battle him again in the future.
Manectric and Wattson
Electrike returned in Manectric Charge. When Ash and the others revisited Mauville City, Team Rocket tried to steal all of their Pokémon. However, Wattson and Watt arrived to stop Team Rocket in their tracks once again. Electrike tried to use Thunder Wave on their balloon but the attack had very little effect. When Watt's Ampharos freed the Pokémon with Iron Tail, Electrike finished the trio off with Thunder Wave along with Pikachu's Thunder and Ampharos's Thunder Shock. After the battle, Electrike evolved into Manectric.
Ash and his newly caught Torkoal took on Wattson and Manectric in a practice match. Torkoal started things off with Overheat which fazed Manectric a bit. When Torkoal used the move again, Manectric took very little damage this time due to Overheat's effect of getting weaker. Torkoal switched to Flamethrower which made contact with Manectric, but it shook off the attack. Manectric then started to use a combination of Charge and Thunder Wave while Torkoal countered with Overheat. Due to Overheat's weakening power, Thunder Wave got through and struck Torkoal, leaving Manectric victorious.
Personality and characteristics
Electrike has a playful nature, allowing it to bond with Wattson and restore his interest in battling.
Wattson's Manectric debuted as an Electrike in Plugging Past Electrike I, where he was used to battle the children that challenged Wattson to a Gym battle. Together with Wattson's two Magnemite, he easily defeated the children. After arriving in New Mauville, Wattson becomes captured by the generator powering the area. Electrike, along with Magnemite, manages to escape and gets Sapphire and the Robot King to help. During the battle with the generator, Electrike used his Lightning Rod Ability to draw in the generator's electricity, allowing Sapphire to attack and defeat it.
During the battle with Kyogre, Manectric was used to battle the Sea Basin Pokémon, although it proved to be too strong for Manectric to damage it heavily. In Bravo, Vibrava, Manectric was used to battle Amber when the Team Aqua Admin came to prevent Wattson from stopping Kyogre's rampage. First, Manectric faced Amber's Pelipper, easily beating it due to his type advantage.
Having no Pokémon left to fight, Amber borrowed a Nincada from Shelly to battle with Wattson. Despite this, Manectric manages to easily defeat Nincada, until it begins evolving. Nincada evolves into Ninjask, and with its speed, Ninjask gained a powerful advantage over its opponent. To counter Ninjask's speed, Wattson had his Manectric pin its opponent to the ground and attacked itself with a suicidal Thunder strike, knocking both Pokémon out at the same time.
Despite this victory, Amber reveals that his Nincada also created a Shedinja from the evolution. The Shedinja knocks Wattson out and sends him into the water, with Manectric also knocked down soon after. Later, Wattson and Manectric are rescued by Sapphire's Wailord, Lorry, who sent them back up to the surface by using Dive and Water Spout.
Electrike was hiding in some bushes waiting for the right moment to strike. It leaped out of there and took the cake that Red bought from a bakery. Electrike was shown to have leaped in the air per step. Red and his Pokémon follow Electrike, via the footprints it left behind. The footprints led them to Wattson, its owner, and they were eating the cake that Electrike stole earlier. Wattson explained to the group that he had his Electrike take the cake from them in order to hand out a special card. Electrike then hid in a trash can with Wattson and they leap out, with Wattson giving the guy the same card given to Red. Clefairy didn't like Wattson's tricks so Electrike growled at Clefairy for disagreeing. Electrike goes inside a Christmas tree store and when Wattson opened the door to his office, it turned out to be completely empty and in ruins. Clefairy dressed up as Santa Claus and had Electrike become his reindeer to deliver presents. Electrike takes off with Clefairy and the presents on the sleigh. As Wattson joined along, Electrike stayed behind to guard the presents while Wattson and Clefairy delivered them. After delivering the presents, they returned to the department store and found out that all of them were from the store itself, with Electrike feeling upset.
