I was so excited to see how Amanda Waller was going to impact the Injustice universe. I already expected her to be a long standing anti-hero and then she gets blown up by Batman.
Speaking of which, it’s obvious this isn’t the Injustice Batman. My guess is it’s either Jason Todd, or Azrael, pretending to be Batman. The guns and red eyes makes me think it’s Jason because of the similarity to his Batman costume in Battle for the Cowl.
Edit: next issue shows Amanda Waller and Rick Flagg definitely dead.
