Lol, I believe Sugimura wrote superhero shows for Japanese television before he was invited to write BIO2. This is the reason why in 1998, some fans did not accept the game and criticized it for the lack of Resident Evil essence, since the original was more pure horror.
The series began to develop more action, and the next generation of mutants with Birkin was planned back in the 1990s, when they were designing Spencer's son. I believe they just delayed the inevitable.
Funnily enough, even Chris Redfield himself mentioned comic books when talking to Wesker. The Resident Evil series, as well as the horror genre in general, has points of contact with the superhero culture, thanks to which so many Resident Evil fans are also fans of comic books. But personally, I like Resident Evil for the fact that there are quite strict rules of the world, so you can't add gods and robots to one world just like that.
