Khal Drogo will be the king of the sea for DC.
This has been a long gestating rumour, not only that Aquaman would make an appearance in the new _Man of Steel-Verse_ but that Momoa would be playing him.
Everyone is sworn to secrecy but [HitFix](http://www.hitfix.com/motion-captured/jason-momoa-will-play-aquaman-in-dawn-of-justice-and-we-know-how-it-will-happen) has confirmed that it’s happening, and happening fast. According to them the character design is finalized already so they can start shooting.
They also say that the reason he shows up at all is to say “wtf were you doing?” to Superman after the World Engine wrought havoc on Indian Ocean in Man of Steel. Similarly the big rumour is that Batman is showing up to do something about the man of steel for destroying Metropolis during his fight with Zod.
I’m not exactly bullish on the prospects for DCs movie plans, it seems like they’re doing the opposite of what’s worked for Marvel (establishing the team _before_ we give a crap about the characters) but I do like that they’re actually continuing the story in a way that deals with consequences for Superman. Yeah, he beat Zod, but the world was nearly destroyed and he was basically personally responsible for much of Metropolis being reduced to rubble.
Batman v. Superman: Dawn of Justice, yes they are still calling it that, will be out spring 2016.
