From Bulbapedia, the community-driven Pokémon encyclopedia.
Glacine (Japanese: ヤジン Yajin) is a character appearing in both White—Victini and Zekrom and Black—Victini and Reshiram.
She is the leader of the tundra village where Damon travels during his quest for support from the People of the Vale. Initially she does not support Damon's goals, but when he rescues her and some of her people from a giant iceberg using his Reshiram and Reuniclus or Zekrom and Gothitelle she changes her mind, along with the rest of the village. She is later seen in Mannes's home voicing her support for Damon, and again in the film's credits helping to rebuild the Kingdom of the Vale.
