Spider-Man: Homecoming - 11 Things From The Comic You Need To Know
7. Black Cat Plays A Key Par
By 1984, Spider-Man and Black Cat had a close relationship in the comics. In the run up to Secret Wars, Felicia Hardy had been in love with Spider-Man, but then lost interest when she saw him unmasked, because apparently she had a mask fetish. They stayed together ultimately, but with Spidey away fighting on Battleworld, Felicia sought a means to gain super-powers (thanks to one of Spider-Man's enemies) to stop being a liability to Spidey and almost getting killed.
Because she turned to a mysterious benefactor to help her, she ends up being infected with a hex designed to create bad luck for Spider-Man through proximity. In Homecoming, she attempts to get in touch with Spider-Man to warn him about the threat to him, but is unsuccessful.
Further on in the arc, Peter eventually breaks up with her - which is entirely understandable given the fact that she doesn't actually love him out of costume - and marries Mary Jane, to Felicia's disgust.
How It Would Work In The Film
In all honesty, it's more likely that Homecoming will reintroduce Mary Jane as Spidey's love interest, but there's a distinct possibility that Felicia Hardy could be introduced as a fellow schoolmate and a potential side-chick.
