While the character is identified as Ruby, some think that it may just be an alias, and the character will be none other than Blade’s daughter, Fallon Grey.
According to Daniel Richtman (via Disinsider), Ruby carries the weight of her upbringing and the events happening in the world around her.
Allegedly, a casting call for the project is looking for a character named Ruby, who is a teenager and will play a strong supporting role in the film.
