>>93231973>Etrigan and MeraThese are my guesses. I don't think the woman with the points is Enchantress, it doesn't line up right, where as Atom's is 1:1 his CW render.
I think it's Mera, and the points are her crown. She's a big player in the upcoming movies, being in both JL and Aquaman.
I think the third silhouette is Captain Boomerang. I don't see cat ears, I see the edges of his hat, I see his jacket collar around his neck, and it even seems like he has the jacket "skirt" down by the waist.
