Empress Underg

Empress Underg (カイゼリン・アンダーグ, Kaizerin Andāgu) is the secondary antagonist of Soaring Sky! Pretty Cure. She is the leader of the Underg Empire. She rarely speaks to her subordinates, only choosing to do so if they have had multiple failures. It is later revealed that she is the daughter of the late Emperor Underg, who Skearhead killed prior to the events of the series. To get revenge for the events of 300 years ago, she goes out to confront the Pretty Cures; while they are able to purify her, Skearhead impales her after she is saved. However, Mashiro is able to heal her injuries.
