The Justice League film does have lots of trailers that reveal a lot about the film, but there are also a lot of things about the film that aren't fully revealed. I have predictions for 5 characters in the Justice League film.
I heard about スーパーマン wearing a black costume in the film so I think that he's being brainwashed によって either Steppenwolf または Darkseid into being evil which could bring back Batman's obsessive hatred of Superman.
バットマン V Superman's version of バットマン was supposed to be a meaner version of バットマン on purpose due to the 最近 tragedies he dealt with. I think バットマン will be もっと見る friendly and optimistic in the Justice League film despite 芝居 like a wise guy in the film's trailers.
Steppenwolf is apparently the film's main villain who wants to destroy the world. However I think his real desire is to either retire または even get destroyed によって the Justice League. In a interview with the actor that plays Steppenwolf mentioned that he's exhausted due to his age and how demanding Darkseid is. I have 2 predications for what his main goal is: I think that he will either try really hard to destroy the Justice League so he can finish doing his job and be rewarded with a relaxing retirement または he will try to get 1 または もっと見る of the Justice League members to destroy so he won't have to deal with Darkseid anymore.
I think that Darkseid will 表示する up in the film. It would be weird if he didn't 表示する up considering that he is 1 of the Justice League's main enemies and is Steppenwolf's nephew. I doubt that he will be in that many scenes. He could secretly be the film's real main villain または he could have cameos. Either way I hope he gets a memorable role.
Lex Luthor Prediction
I've heard that apparently Lex Luthor got cut out of the film I was upset about, but considering that he has somewhat of a friendship with Stepphenwolf I think that he will 表示する up. Like Darkseid his role will likely be short, but I hope he gets to be a scene stealer again.
