The Wonder Woman Universe
The appearance of the Amazons is Justice League’s strongest connection to both the Wonder Woman film and the comics. In addition, Steppenwolf senses that Wonder Woman has the blood of the Old Gods (the Olympian Gods in the comics) flowing through her veins.
The shot of Wonder Woman on the arm of the Titan Themis is an indication of this. The Olympian Gods are descendants of the Titans, so Diana is related to Themis.
In the most important reference, Bruce Wayne physically pushes Diana and mentions Steve Trevor. As big a douche as he is, Bruce’s point gets through. Frankly, that was one of our favorite scenes in the movie.
Also, and this might actually fit into the Batman category, there’s the romance and/or sexual tension between the two characters. Although it appears that all of that fell apart when Wayne mentioned Trevor, we wouldn’t bet on it.
Lastly, we have that classy lady who’s taken away by the police and the girl wearing cat ears standing nearby. Is that a reference to Catwoman? Or Cheetah?
