Zhora was a WR400 android and probably the cut fourth playable protagonist in Detroit: Become Human. She is a female Traci who had an initial story arc written by David Cage, but he later made the decision to remove her, due to the increasing complexity of the branching narrative.
Overall there is little information about Zhora. According to concept artist Mikael Leger, "Her initial story arc was amazing". It is possible that she was reworked to become North in later drafts, since they presumably had similar backstories, and similar appearances.
