Justice League will be released this year in the end and no information regarding the role of Henry Cavill aka Superman is revealed so far. Batman and Wonder Woman will be seen gathering the team.
Superman is most likely to be seen as an antagonist and the whole Justice League team as protagonist until he gets regathered by any of the team member (most likely Batman).
Superman wearing black suit indicates that he would be with a whole new concept in his mind and may be seen saving the world from enemies all alone.
However, this one seems to be a little too off-the-notch, Superman playing the villain at first and then restrained in the team would be more likely ti happen.
If this image is to be believed (which is very believable), those who follow comics would be pretty happy to see their dream come true. Zack Snyder did follow the comic book life by killing Superman to highlight the Death of Superman incident.
The image released is blurry and this somehow gives a hint of it being fake. But a whole lot of allegations have been made regarding Superman wearing black suit in Justice League movie this year.
Hundreds of fan arts have made it through the internet teasing Henry Cavill’s Superman in a black suit. Also, Henry Cavill himself posted a photo of him wearing a black Superman suit. All these things could only be answered with a trailer featuring Superman or an official image released by Warner Bros.ScreenRant/CinemasComics/Screen Geek]
