Raichu first appeared when she was introduced to Ash, Serena, and Bonnie. Unfortunately, Raichu, along with her dancing partner Wartortle and Ash's Sliggoo, were captured by Team Rocket. They managed to escape after Jessie's Pumpkaboo use Shadow Ball to knock the cage over a cliff and shattering it to pieces. Tierno and Bonnie arrived and found them, but when they confronted Team Rocket, they started a forest fire by accident. Sliggoo bravely used Rain Dance to douse the fire and surprisingly evolved into Goodra. Goodra then blasted Team Rocket off with its newly-learned Dragon Pulse move. Raichu tag-teamed with Wartortle in a double battle against Ash's Pikachu and Goodra. Raichu used Charge Beam on Goodra, who used Bide, absorbing the attacks. Raichu used Focus Blast, attacking Goodra, who still absorbed the attacks. Raichu repeated the attack, which hit Goodra, who fired Bide, hitting Raichu and Wartortle, nearly defeating them. Raichu tried to use Focus Blast to free Wartortle, who was grabbed by Goodra, but Goodra threw Wartortle onto Raichu, canceling the attempt. Pikachu used Thunderbolt and Goodra used Dragon Pulse, defeating Raichu and Wartortle.
Raichu reappeared in Valuable Experience for All!, where Tierno used her as his second Pokémon in his battle against Sawyer at the Lumiose Conference. She first battled his Aegislash, who had previously defeated Ludicolo. Raichu began the battle by using Charge Beam, which was blocked by Aegislash's King's Shield. Although Sawyer had Aegislash use Slash, Raichu was able to avoid the attack and strike back by using Dig, knocking the Ghost/Steel-type out.
Raichu then battled Sawyer's second Pokémon, Slurpuff. However, the Fairy-type used Attract to infatuate her. As a result, she ignored Tierno's bidding to use Charge Beam. After being hit by an Energy Ball, Tierno recalled her and sent out his Blastoise.
After Sawyer's final Pokémon, Sceptile, defeated Blastoise, Tierno sent Raichu out for a second time. He had her use Thunder, which wouldn't miss because of Blastoise's parting Rain Dance, but Sawyer revealed his ace and Mega Evolved Sceptile. Momentarily stunned, Tierno ordered Raichu to complete her attack, but the resilient Grass-type was rendered unfazed, due to Lightning Rod. Sawyer commanded for Sceptile to use Dragon Claw, and after a failed attempt to counter with Focus Blast, Raichu was defeated, eliminating her Trainer from the Lumiose Conference.

- The inconsistency where Raichu's tail is of the male variant was fixed on Hulu's Japanese service in the Japanese version of Valuable Experience for All! and Raichu's tail was corrected to the female variant. Other versions of that episode still have the male variant of Raichu.
- ^ In XY126: Valuable Experience for All!, Clemont points out that Sawyer's Slurpuff and Tierno's Blastoise are both male, confirming that Raichu is female. The tip of its tail being identical to a Male's is an anime inconsistency.
