Justice League: Every Character Confirmed So Far

8. Mera

Confirmed By: She's in the trailer.

Plot Prediction:

With the battle for the Mother Boxes going to Atlantis - which houses one of the artefacts for its protection and the security of the world - it's inevitable that we'll see all of the underwater land's key players.

And as shown in the trailer, it would appear that Queen Mera - married to Jason Momoa's Aquaman - will be taking a hands-on approach to defence of their Mother Box when Steppenwolf comes calling.

She probably won't be heavily involved aside from that scene, but at least we'll get to see the first real look at Atlantis around her.
