In the midst of the Grand War, Patricia was kidnapped by slave traders under the employ of the Medici Family. She was later rescued by the staff of Anti-Skullgirl Lab 8. With her consent, she underwent Project:Peacock, becoming one of the best ASG soldiers in existence. The eyes of the Argus System expand her vision and fire specialized Z-rays, and the Avery Unit grants some uncanny hammerspace...among other effects.
Time as a war slave hasn't been kind to Peacock's psyche. She's developed a penchant for murder and mayhem, but keeps even that in check when it's movie time.
