Bear in mind, this news contradicts one of the details from Nikki Finke's Thursday report, claiming that Aquaman would not appear in the May 6, 2016 release and would instead make his debut in Justice League. It does, however, tie back to a report from last December that suggested Momoa had met to read for a mystery Batman v Superman: Dawn of Justice role.
TheWrap's Jeff Sneider then took to Twitter, posting his own Justice League rumor, claiming that Martian Manhunter will appear alongside Max Lord and Darkseid. The Tweet, with an accompanying image, appeared as follows:
No Martian Manhunter in JUSTICE LEAGUE? Not according to this agency grid, which lists DARKSEID as the villain... pic.twitter.com/lLwFwkXLkv
