It isn't exactly a stretch to say that the Marvel Cinematic Universe has something of a woman problem. Despite being around for nearly a full decade, the majority of Marvel's properties have focused on men, with only three of them -- Agent Carter, Jessica Jones, and arguably Agents of S.H.I.E.L.D. -- not shin gin the majority of the spotlight on men. The majority of women in this universe, to the frustration of many, have been in supporting roles, and no matter the metric you want to go with, Captain Marvel being the first female-led film in this universe in addition to the 21st MCU flick is just a bad look.
But things are looking up; Tessa Thompson, a recent MCU addition as Valkyrie in Thor: Ragnarok, recently said that women are going to really have the spotlight in the next phase following Avengers 4. Since being added to Marvel's roster, Thompson has been championing for a superhero movie with the various women of the MCU taking center stage, not unlike the recent A-Force comic series. In addition to Valkyrie, this would include Evangeline Lilly's Wasp, Zoe Saldana's Gamora, Letitia Wright's Shuri and whoever else is remaining in the aftermath of the battle with Thanos. And if Marvel Studios really is going to put women at the forefront going forward, one of them should be Fallon Grey, the daughter of Marvel's vampire killer, Blade.
If you haven't heard of Fallon, it's hard to fault you for that; she was originally slated to debut in a solo comic back in 2015 from the creative team of Tim Seeley and Logan Faeber. Seeley, aware of the optics of an all-white creative handling handling a book about a young black woman, opted out of the gig in the hopes that a black woman would instead get to write Fallon. Sadly, nothing ever came of her after that, and given some of Marvel's recent cancellations, it's probably a safe bet that she wouldn't have lasted long. That said, a film or TV series about a young black woman as a vampire hunter would be a better format for this character, especially when she's got the added bonus of her dad being the first popular mainstream superhero movie.
