Ghost of Maiden's Peak

The ghost of Maiden's Peak (Japanese: ???) is a character in Pokémon: Indigo League.

Season 1: Indigo League
The ghost was a woman 2000 years ago whose husband went in a war. She went on a peak waiting every day for him to return back, but did not show up. Her ghost still roams the peak to wait for her husband to return.

When the heroes and Team Rocket solved that a Gastly was using an illusion to keep the maiden alive, the Gastly promised that if he saw her husband, it would tell him his wife is waiting on the peak.
