"The short story is, I quit," Seeley explained in an interview with Newsarama. "The long story is when Marvel hired me, I had just written ten years of a horror comic starring a female lead so I seemed like a good fit. So we threw around ideas of doing Blade’s daughter and when they announced it, Marvel was in a weird place because they had announced the hip-hop covers and a lot of people saw 'here’s another black lead with an all-white creative team' and you know it’s valid and definitely the case."
Seeley agrees the criticism was justified, and not entirely unexpected, but Marvel worked with him to find a path forward. "After a while, I felt like it was me screwing this up. I couldn’t help but feel like a black woman might write this stuff better than me and saved them from me. In the wake of 'Black Panther' launching so well, maybe 'Blade' is the book they find new talent on."
Seeley's planned Blade series with artist Logan Faerber would have seen the Daywalker questioning his mission and his daughter, a new character called Fallon Grey, taking charge of killing monsters.
"My take on Fallon is that she’s an 'anti-Peter Parker,'" Seeley told CBR when the series was announced. "She’s popular, well liked, and everyone around her thinks she has the future by the balls. But those kind of expectations come with their own stresses, and part of Fallon’s story will be dealing with what people expect her to be."
"Initially, their relationship [between Blade and Fallon] is all about what they share — a stubborn refusal to change or see new viewpoints," Seeley said at the time. "They’ll be completely and totally antagonistic, and the fun will be in seeing whether a guy like Blade can become a father, and whether a girl like Fallon can become a student and a daughter."
Though Seeley is currently exclusive to DC Comics and serves as the writer of "Nightwing," he said in the Newsarama interview that he would be more than happy to work with Marvel again in the future. "I love the people there. Katie Kubert was one of my editors at DC and I loved working with her. She was one of the people that suggested me for 'Grayson.' I liked working with those characters and people."
