she could be mystey

Answer 2

Answer:

Serena

Serena is revealed to be a childhood friend of Ash's in the anime, a popular trope that surprisingly hadn't made its way into the show at that point. Serena has had the most character development in the series, and by the end of her stint had cemented herself as one of the series' best companions.
