Cybersix, alternatively spelled Cyber-6, is the titular character, hero and protagonist of the Cybersix series and is voiced by Cathy Weseluck. Cybersix is a genetically engineered superhuman and sole survivor of the massacre of her five thousand brothers and sisters by orders of her creator, Doctor Von Reichter. After narrowly escaping death, she flees to the city of Meridiana where she takes up the identity of a male professor named Adrian Seidelman while donning a black leather outfit as a woman during the night. She would be confronted by her creator and his clone-son, José, and their numerous creations antagonistic to her, as well as being aided by her long-lost brother, Data 7, whose mind had been transplanted into the body of a black panther. She struggles with the idea that she is a creature rather than a human being capable of love and emotions, emphasized with her relationship with her work colleague and friend, Lucas Amato and her dependence on Sustenance.
