V for vendetta spoilers?
Now I've found the part that he says that the character before was called the doll and basically wasn't made because execs didn't want a "transsexual terrorist". The article is written in 1982 or 3 so wording is find there but he does describe the character of the doll as freakish. I'm unsure if that's to do with the transness tho considering he actually doesn't bring up the trans part until the bit about it getting rejected? Implying that wording is meant to be inferred that way? Its not clear but then we see parts of the books story that are very trans coded mostly in illusions to hormone experiments once V enters the concentration camp, the lesbian cell neighbour story could be V we don't know, the idea of V removing Envy's gender expression as part of the simulation they make her go through which leads her to act androgynous for the rest of the book, the woman researcher wanting to see V's face and calling it beautiful before she dies, and the fact that V says Envy must never actually see V's face and that could be read into not wanting to see what it became.
Most of that I got from an article that argues this but also never mentions the bit about the doll which I got from the article Alan Moore wrote in Warrior #17 that then got put at the end of the novel version of V for Vendetta called "Behind the painted smile" which I could not find online. Had yo use my big copy from reading a random blog who says they read it from the back of the book.
