In the comic books, the character is the wife of Aquaman and a former Queen of Atlantis. However, she hails from Xebel, a watery dimension inhabited by an exiled group of Atlanteans. Mera actually has the ability to control water and use it as a weapon.
It remains to be seen how she’ll factor into Justice League, but expect to see her fighting alongside Aquaman. It’s entirely possible that she’ll end up becoming a member of the team, though some previous reports have pointed to the actress playing a relatively small role here. What we do know is that Heard will return for a larger part in James Wan’s Aquaman.
Given her widely publicised divorce from Johnny Depp, there was some doubt that the actress may be unable to star in Justice League, but we obviously now know that thankfully won’t be the case. Click through the gallery below for some pretty cool concept art too.
