Yancy is a character appearing in Pokémon Adventures.
Black 2 & White 2 arc
Yancy was seen along with her Spinda talking to Blake. Blake broke up with her due to the fact that she was an idol and he might be getting in the way with that. Yancy however didn't agree and didn't want Blake to leave. Blake then said that it would be better if they broke up and left, leaving Yancy behind crying.
