The president of the BW Agency, a company that has a large supply of Pokémon actors that can be used for commercials, plays, movies, and stunts.
White is often seen with a female Tepig, one of her main actresses for commercials, which quickly became friends with Black's male Tepig. She employs Black due to him destroying their equipment whilst saving them from a Galvantula, so he loans out his Tepig for commecials to pay her back.
Despite always being surrounded by pokemon, she is not a trainer, and cannot battle, leaving Black to protect them when N ambushes him.
as an agency president, White is shown to be very astute at doing her job, and was able to hold her Pokemon Musical in Nimbasa City successfully, even finding a smart alternative method to deliver her supplies to the musical, even with time constraints.
While leaving the musical she gets kidnapped by a member of Team Plasma and is taken to the Rondez-View Ferris Wheel where she discovers N and Servine are in the same car with her. N asks her about why she created the Pokémon Musical, White reveals her reasons to him. N replies that some Pokémon may like to perform but by only focusing on that part of the Pokémon, their other traits will be suppressed. In Gigi's case, N refers to her ability to battle and evolve. N then has his Servine attack Gigi in order to have her fight back and show just how strong she is to White. N comes to the conclusion that by focusing on Gigi's talents in performing, White had been neglecting her true strengths in battle, a fact that Gigi agrees to. When White decides that it is time to escape, she attempts to jump off the Ferris wheel and asks Gigi to do the same. Surprisingly, Gigi goes to N's side, shocking White who falls out of the car and onto the ground below. Gigi and N watch from the car as White lies on the ground, crying because of Gigi's betrayal. N releases his Servine and has it stay with White.
