Mariah works at a Kanto pharmacy alongside her grandmother, Katie, and her childhood friend McCauley, who make healing potions using electricity. She came across Ash battling with Brock after her Flaaffy was accidentally struck down by Marshtomp's Mud Shot. Brock offered to give it some medicine, but Mariah politely refused. She then carried her Flaaffy back to her grandmother's pharmacy to get healed.
At the pharmacy, Brock wasted no time flirting with Mariah. It was also soon discovered that Marshtomp had an infatuation for Mariah's Flaaffy. Brock automatically took this as a sign that he and Mariah were destined to be together. However, Mariah seemed to have more of an interest in McCauley than Brock.
Later, Mariah got taken away along with the whole pharmacy by Team Rocket, who wanted all the medicine for themselves to sell. McCauley jumped into the flying pharmacy, in order to save Mariah and the medicine. Brock attempted to help out by using Marshtomp's Mud Shot to shoot down the balloon, but Team Rocket reflected it back, and the Mud Shot ended up hurting Ash's Pikachu and Katie's Mareep. They then quickly needed to make potion to make the Electric duo better. Both Mariah and McCauley decided to use their Flaaffy and Ampharos, respectively, to make a new batch of medicine. Afterwards, they used their Pokémon to destroy the engines on Team Rocket's balloon, causing it to crash.
After Team Rocket was defeated, Katie felt confident enough to leave the pharmacy to McCauley and Mariah.
