Emolga made her debut in Emolga the Irresistible! where she used her Attract move to take apples from a group of Patrat. She later encountered Iris's Axew chasing an apple down a hill. She acted kind towards Axew so that she could have obtained food from Iris; however, she ran off after being smothered and almost captured by Bianca. She was later reunited with Iris whose Axew wanted to share his fruit. The trio then ended up deep in a forest filled with hostile Swoobat. They teamed up to try to battle the Swoobat, but Emolga's Discharge and Hidden Power attacks weren't enough to defeat all of them. However, Ash and Pikachu were able to rescue them. Once they were safe, they returned to their camp, where Emolga flew into Iris's arms and accepted capture, much to Bianca's distaste.
In Emolga and the New Volt Switch!, Iris decided to give Emolga some training and she was sent out to battle with Bianca and her Pignite. With one Attract, Pignite became infatuated and was recalled to his Poké Ball. She then battled Minccino but kept using Volt Switch to get other Pokémon, such as Excadrill and Pansage to battle for her. She got into a bit of a scrape with Ash's Snivy who was not impressed by her laziness. However, the two end up settling their differences temporarily when they both worked together to stop a rampaging Simisear and also saved its life from a giant falling boulder.
In Archeops In The Modern World!, Iris sent out Emolga, alongside Tranquill, to help a revived Archen learn to fly. She started off by using Attract which failed, revealing that Archen was also female. After being pecked on the head, Emolga used Volt Switch to leave and send out Stunfisk while she slept in a tree.
In Cilan Versus Trip, Ash Versus Georgia!!, Iris used Emolga to battle Jimmy Ray in the Club Battle tournament. Using her powerful moves, she managed to defeat his Watchog and allowed Iris to advance in the competition. In the next episode Iris used Emolga again to battle Stephan and his Sawk. In the battle, Emolga's Attract was blocked by Sawk's powerful Close Combat, leaving her without her signature tactic. Sawk dominated the battle until he hit Emolga with Double Kick, activating her Ability Static. In order to stall Sawk until the paralysis from Static took effect, Emolga used a stream of Attract attacks, which Sawk was still able to easily knock down. However, while Sawk was deflecting Emolga's Attract, he was unable to let up his fast moves for a second and was stuck until his movements were halted by the paralysis. The side effect of Close Combat, dramatically weakened Sawk's defenses and Emolga was able to defeat him with a single Volt Switch, which she couldn't use previously in the battle because it was a one on one match, however being used to finish the battle would not have broken any rules.
In Battling the Leaf Thieves!, Emolga had a training battle with Ash's Swadloon. The battle seemed particularly even until Emolga got caught in Swadloon's String Shot, where Iris cleverly ordered Emolga to use Discharge, sending a powerful jolt straight down Swadloon's thread and caused him a lot of damage. Eventually, Swadloon evolved into Leavanny and after making many leaf-hoods for the other Pokémon, he turned his attention to Emolga and Snivy. Though Emolga wasn't too pleased with the hood, she still took the chance to poke fun at an obviously embarrassed and uncomfortable Snivy. When the gang awoke from a nap and found Axew to be missing, Emolga was sent to search for him from the skies. On her search, Emolga spied a Durant carrying Axew into a cave and flew back to lead the gang to the cave. Emolga later joined Pikachu, Leavanny and Scraggy in battling a large swarm of Durant so that they could retrieve the still sleeping Axew but the Iron Ant Pokémon continuously defended with Protect. Emolga used Attract to infatuate all but one Durant, which she and the others were able to defeat on their own, allowing Iris to rescue Axew.
In Team Rocket's Shocking Recruit!, Emolga got into trouble with Iris for shocking Oshawott and Scraggy when they disturbed her while eating. Later while she and Axew were playing, Axew was attacked by a wild Galvantula and bumped his head on a large rock. After being blamed by Iris, Emolga left the scene in anger. She later came across Team Rocket who battled her with Woobat and Yamask. Emolga expertly dodged their Air Slash and Shadow Ball attacks before immobilizing them both with Attract and knocked them both out with back-to-back Discharge and Hidden Power. As she taunted them, Jessie and James sent out Frillish and Amoonguss, though Emolga dodged their attacks and knocked them both out too. Jessie began to flatter Emolga and suggested she join their team, allowing Emolga to devise a plan to wind up Iris. Emolga joined in with the Team Rocket motto as they ambushed Ash and co. Emolga got into an argument with Snivy and as they launched their attacks back and forth, one of Emolga's Hidden Power attacks flew off course and disturbed a sleeping Exploud which then attacked Ash and the others. Under the shroud of Yamask's Haze attack, Emolga was able to drag Axew along with her and Team Rocket. Emolga soon let Axew in on her elaborate plan to get back into Iris's good books, unaware Meowth had been listening in. When Iris eventually found her Pokémon, she was able to learn from Axew that Emolga had infact attempted to protect him from the Galvantula, and so Emolga and Axew were about to reunite with Iris. However Team Rocket trapped them both in a glass cage with the Exploud from before. Trapped, Emolga did her best to protect Axew from Exploud's attacks while Charizard and Dragonite used their attacks to break through the glass to save them. Emolga and Axew were soon freed and Team Rocket were sent blasting off, along with the Exploud. With everything settled, Emolga happily began to play with Axew some more.
Emolga can be a strong battler but can also be lazy and gluttonous. She has a particular fondness for apples. She will often use her cute looks to manipulate those around her to get what she wants. Her conniving ways are shown when she uses Attract on Pokémon such as Ash's Oshawott and they willingly give up their food without realizing what they just did. She also uses Volt Switch regularly in an attempt to avoid doing any work, such as battling. Emolga can also be a drama queen as shown when she lied to Oshawott and Axew about three Watchog hurting her when she just wanted to get apples from the Watchog. However, she is still good at heart, as she tried to protect Iris and Axew from a group of Swoobat and thanked Ash's Snivy for helping her, Oshawott, and Axew get out of a scrape with a Simisear a little bit later. In Facing Fear with Eyes Wide Open!, she was shown to still hold some animosity towards Snivy. Also in Movie Time! Zorua in "The Legend of the Pokémon Knight"!, Emolga and Snivy were seen fighting again, and while fighting they dumped paint on both their Trainers by mistake with their tails.
