casting call for the upcoming Blade reboot starring Mahershala Ali may tease the arrival of the Daywalker's daughter, Fallon Grey.

Murphy's Multiverse reported that a call went out for a teenage girl named Ruby, described as "thoughtful, serious, and burdened by growing up in a complex world." No further details were given on the character. While nothing is known about the plot of Marvel's take on the vampire-killing hero, fans have long wondered if a younger version of Blade, like his daughter, could appear in the film and provide the MCU with yet another teen legacy hero. As is often the case with casting calls, the name "Ruby" could be a cover for the character's actual name or just a movie update on the source material.
I'm hoping that 'Ruby' is just... Ruby. I'm very much not feeling Blade having a daughter now and shoehorning in an absentee father angle (bad look for a black hero in particular), plus there's inevitable "Black Buffy" fan talk about spinoffs, and the risk of sidelining the main character by introducing an all new person (see Blade Trinity, the Nightstalkers) instead of concentrating on the new Blade's context in the MCU (and whoever the villain is), and an extremely bad risk of pushing the franchise in a semi-comedy direction for the sake of humor. "Fallon" to date has never seen a printed comic, why are some people treating it like canon? It's not even a "What If?" story yet...
