A blonde 14-year-old girl from the Virdian Forest. Yellow is quite naive, and acts very much like a little child. She hates it when Pokémon are injured, hers or her opponent's, and has developed a style of battle in which neither her nor her opponent's Pokémon are hurt unless it is absolutely necessary. Despite her child like nature she can be very serious when people and places she cares about are threatened.

A high-pitched female voice is needed.
