The Beginning series
Ritchie sent Sparky to battle Team Rocket, alongside Ash's Pikachu. Jessie's Arbok tried to attack, but both Pikachu used Agility to circle around Arbok. Next, both Pikachu used Thunderbolt, which blasted Team Rocket away. Since Ash, Ritchie and their Pikachu were hanging on a cliff, they sent their Butterfree and Pidgeotto to fly them away.
Ritchie sent Sparky to battle Ash's Charizard. Despite Ash's warning it was much tougher than it looked, Charizard tried to gust Sparky away and succeeded. However, as Sparky began charging, Charizard laid around lazily and refused to battle, thinking Sparky was not a good enough Pokémon to battle. This costed Ash the victory, as Ritchie and Sparky were declared the winners of the match.
Sparky continued to battle in the Pokémon League. Ritchie faced Assunta, whose Ivysaur dodged Sparky's Thunder Shock. By using Vine Whip, Solar Beam and Tackle, Ivysaur managed to defeat Sparky. Later, as Ash spoke with Ritchie, they fell in a hole made by Team Rocket and their Pikachu were stolen. Fortunately, Ritchie and Ash managed to free themselves and take back their Pikachu, as well as to blast Team Rocket off. Richie, Ash and their Pikachu attended at the closing of the Pokémon League, seeing they had a great time, even if they lost.
Sparky, along with its trainer, appeared in the opening scene of Adventures on the Orange Islands.
Gold and Silver series
As they came to Whirl Islands, where a fabled Pokémon was living, the heroes encountered Sparky. Soon enough, its trainer, Ritchie, arrived and greeted the heroes. Team Rocket arrived and tried to trap Lugia's child, Silver. Sparky and Ash's Pikachu emitted Thunderbolt to keep Lugia away, but failed.
With the heroes being captured, Dr. Namba wanted to take control of Sparky and Ash's Pikachu by placing some mind devices on them. Fortunately, Oliver freed Ash and Ritchie in time to stop the devices from taking effect. Namba triggered the alarm, so Butch and Cassidy arrived, having Houndour and Hitmontop attack with Flamethrower and Rolling Kick. However, both were tackled and defeated by the Pikachu. Thus, Dr. Namba sent Electabuzz, who attacked the Pikachu with Thunder Punch, but missed. However, Namba took greater control of Electabuzz by intensifying its rage, causing Ash's Pikachu and Sparky to get hit by its attack. The Pikachu fired Thunderbolt and hit Electabuzz, who failed to attack them with Thunder Punch. The Pikachu repeated their attacks, which were reflected by Electabuzz's Light Screen. Electabuzz fired its own Thunderbolt, but missed. As a part of the plan, Ash's Pikachu used Thunderbolt, which was stopped by Light Screen. However, Sparky fired another Thunderbolt, which electrocuted Dr. Namba, shattering his remote. Electabuzz's mind device was destroyed and Electabuzz was defeated by Ash's Pikachu and Sparky's Thunder.
