The Spider-Man comic book writer who created Madame Web's villain is just as confused by the trailer as you are. J. Michael Straczynski, who created the antagonistic Ezekiel Sims, shared his thoughts on the Sony/Marvel trailer after the clip attracted chatter online.
"And well, this just happened," he tweeted, attaching a link to an article headlined 'Madame Web’s First Trailer Introduces Spider-Women, Deep-Cut Villain'. "It's definitely the character I created for Spidey, but it feels like they may have merged it with Morlun a bit. (Don't ask for any details because this is the first I'm hearing of it, so my guess is as good as yours.)"
