DC Comics Universe and Batman / Superman #1 Spoilers follows.
ALL Members Of The Secret Six Revealed!
Who Did The Batman Who Laughs Infect?
UPDATE:
Based on feedback from social media, it is clear that Hal Jordan Green Lantern has his ring hand up in a fist, but it is not touching his face. Blue Beetle is touching his own face which was, for me, hard to see on the first few passes due to the coloring.
ORIGINAL:
Well, DC Comics did say the clues were in their teaser art.
It is clear that the characters that are touching their face in the pic are the Secret Six infected by the Batman Who Laughs. We knew about most of them starting with Commissioner James Gordon…
…Shazam…
…Supergirl…
…and Hawkman.
Looks like the remaining two Secret Six members are Hal Jordan Green Lantern Blue Beetle and Donna Troy. Not Superman or Batman as swerved by DC Comics.
Batman / Superman #1 hits stands on August 28, 2019.
