Just posting the final page for the Shazam backup story from Justice League # 10 featuring Black Adam.

It’s pretty obvious that Teth-Adam will be working with Dr. Sivana in the near future. Right now, lets just marvel at the somewhat new costume the anti-hero has been seen wearing. 
Also gotta hand it to Geoff Johns and Gary Frank for such a great backup story running concurrently with the main Justice League story.
