Kay is a part of a Pokémon showboat show where she provides the voice over to her Raichu. Kay could instantly tell by looking at Ash Ketchum and his Ash's Pikachu that they were close friends.

Kay was very excited to see Raichu for the first time and as she was giving it a hug, its cheeks sparked and Kay got afraid and threw Raichu at a crate. Since then she been afraid of being shocked by Raichu. Kay and her Raichu were very nervous with each other since that encounter with Raichu's cheeks sparking when it got nervous and then Kay would flinch at the thought of a potential Thundershock. With Ash Ketchum's help and an encounter with Team Rocket when Kay rescued her Raichu from being hurt, the two of them got over their nervousness of each other.

Roger ended up getting sick from James's Weezing SmokeScreen and it also damaged his throat so he couldn't talk well enough to do his performance. Kay and her Raichu took his place in the Pokémon Showboat's performance along with Ash Ketchum and his Ash's Pikachu.
