Ghost Girl

The ghost girl is a specter and a character of the day that appeared in Ghoul Daze!. She is an evil spirit that tries to capture humans and bring them to the spirit world.

She first appeared in the bushes, waving her hands and asking Conway to play with her. She hypnotized Conway and tried to make him walk off a cliff, but Dusknoir saved him. The ghost girl also lured Meowth with food, but Dusknoir appeared to stop her.

The girl later beckoned Ash and Angie to follow her to the Summit Ruins. Then, the girl tried to coax Ash and Angie into the mysterious cave, which was actually the entrance to the spirit world. Dusknoir prepared to attack the girl, but Ash and Angie battled Dusknoir to protect the girl. Dusknoir turned around to protect the two, blasted the girl into the spirit world, and collapsed the cave entrance, leaving her trapped.
