D:BH Deleted Content: Possibly Zhora.
Back when I was first getting sucked into the fandom and browsing concept art last year, I had encountered a blog mentioning a 4th playable character. Albeit not dropping a name, the artist commented she was scrapped during development and her model was reused as an NPC at Eden Club.
Concept Artist Mikael Leger commented on the Eden models: "Tracy! Her initial story arc was amazing…" As well as: “Remember Zhora?”
So I looked further into the NPC’s at Eden Club. One of the models with closest resemblance to the concept of Tracy/Zhora would be this one:
Her facial template is fairly unique, as other models with her likeness can’t be found outside of Eden Club. Her face is noticably less textured than the other Tracis at the club, as if she was an early or last minute addition.
Her official Eden model is a brunette with green eyes, however she has a dormant platinum blonde swatch hidden in her texture file along with a reddish and pink swatch. In the pictures above you can see how “Zhora” looks like with her dormant plantinum and reddish swatches activated.
Unfortunately, the preset shaders coloring her hair are very oversaturated. Only the extracted facial texture itself shows the true honey blonde color originally intended for her model. On the side of her left ear you can see her hair being pulled up into a bun, just like in her concept art attached on the right.
Artwork Pack 05 in the official gallery contains this concept art of an android at Ferndale Station. She strongly resembles Zhora, same hair, same coat and black high heels.
It's also noteworthy that Zhora bears a striking similarity to Marla, who later evolved into North along with Markus’ human love interest, Riley. While Zhora and Marla sported long blonde hair, North ended up using Riley’s likeness (red hair and long braid). Since Zhora and Marla/North share their tragic backstory at Eden Club, it is possible they were intened to be the same person at some point during development.
