Ava's Mother supports her daughter's journey with the Pokémon Trading Card Game. Residing with the family in a new town following a move, she exists within the context of Ava's school adjustment challenges. During the school's club week, she offers practical assistance by packing Ava's belongings, including a notably heavy backpack intended for the bee club that inadvertently causes Ava difficulty.

Her personal history with the game surfaces through a deck of "retro" cards she owned in her youth. Ava discovers this deck after the family's relocation, leading to its use in Ava's initial steps into the game. She later confirms her past competitive play during her own childhood, recounting a specific, deeply affecting loss in a championship final. This revelation occurs when Ava reveals prior awareness of the deck's origins.

Her involvement extends to attending Ava's competitions, such as the Regional Championships. Her actions sometimes carry a dramatic or emotional tone, like loudly whispering about packing baby powder for Ava's rashes in front of the Pokémon Club members or reacting visibly when recounting her childhood tournament loss. She provides emotional support during Ava's setbacks, notably after the wind incident that caused the loss of Ava's deck cards and following Ava's demoralizing defeat at the International Championships. This support contributes to Ava's renewed determination for subsequent events.
