McCauley works with Cadee and Mariah at a pharmacy where they make potion from electricity. He was having a hard time getting the potions right. He would stay up late at night with his Ampharos just trying to perfect it. He has always striven to be as good as Cadee, ever since he and Mariah were little. Cadee explained that McCauley needed to have more confidence in himself.
Later Mariah gets taken away, along with the whole pharmacy, by Team Rocket who want all the medicine for themselves to sell. McCauley jumps into the flying pharmacy in order to save her and the medicine. Brock attempts to help out be using Marshtomp's Mud Shot to shoot down the balloon, but Team Rocket reflects it back and the Mud Shot ends up hurting Ash's Pikachu and Cadee's Mareep. They needed a potion to make them better and fast. Both McCauley and Mariah decide to use their Ampharos and Flaaffy, respectively, to make a new batch of medicine. Afterwards, they use their Pokémon to kill the engines on Team Rocket's balloon causing it to crash.
After Team Rocket was defeated, Cadee felt confident enough to leave the pharmacy to McCauley and Mariah.
| Ampharos is used to deliver electricity to make the special potions. It was practicing day and night until it got the technique correct. During the arrival of Team Rocket, Ampharos was in the carried shack that Team Rocket tried to steal for the boss and tried to make a potion for Cadee's Mareep and Ash's Pikachu when they got hit by Marshtomp's Mud Shot. After doing so, Ampharos along with the other electric Pokémon sent Team Rocket blasting off.
Ampharos's only known move is Thunder.
