WONDER WOMAN TO JUSTICE LEAGUE
At the end of Wonder Woman, in the present day, Diana hears danger and suits up to go stop it, and that is where the film ends. I do not believe that the big bang that was heard was Parademons or Steppenwolf coming to Earth if it were it would be shown, or we would at least get a post credit scene.
In the film itself, I tried looking for a mother box the Amazonians may have on Themyscira, however, I could not find anything. It seems like Hippolyta didn't even tell Diana about the time she defeated the first Darkseid invasion with the Atlantians and Humans.
With the letter from Bruce Wayne, that was kind of set up for Justice League, just showing you that Bruce is in contact with Diana, so when he assembles the league, he can get her with no worries. We may get a scene where Diana talks to Bruce about her origin, but just little snippets.
The development of Diana in her own film will make her more of an asset to the Justice League, with her being a literal god and all. I am curious to see whether we will see the full extent of her powers in the film, we may not just to keep a relatively fair fight, not only for Steppenwolf but also for her own team, she can swim as fast as Aquaman, she has fast reflexes like the Flash, she learns many languages so she could learn binary and be smarter the cyborg, but she would need Batman to give her money.
Anyway, comment below on your excitement for Wonder Woman in Justice League. I am just glad we only have to wait 5 months to see Gal Gadot again as Wonder Woman. As always thanks for reading, take care.
