Hints at new Fantastic Four movie villian

So everyone has been focusing on the cast of the new Fantastic Four movie. The casting choices have been polarizing. Some like the choice, some dislike it, and some are insulting to those who do not agree with it. Regardless of your stance on the actor selection, we know we will be getting a Marvel Villain appearance. If recent history is any indication, prices on the character’s first appearance will heat up.
So who is the villain. It has not been confirmed yet, but Jon Schnepp tweeted that it could be Annihilus. Jon Schepp is noted as:

a trusted source for this kind of insight into the comic book filmmaking industry, having mentioned numerous times before how he knows a lot of the special effects artists personally, people who’ve been working on the project since day one. AMC was reporting Simon Kinberg had finished doctoring the script for Josh Trank’s Fantastic Four reboot and we should be hearing the official casting announcements soon enough. While remaining optimistic towards Variety.com’s shortlist of bizarre choices for lead actors, Schnepp nonchalantly chimed in with Annihilus as an aspect of the newly completed script.

Annihilus’ first appearance is in Fantastic Four Annual #6 which starts as little as .99 cents, and is also known as Fantastic Four King Size Special #6 which has copies starting as little as .50 cents.
