Specifically, Jason Momoa’s Arthur Curry a.k.a. the titular hero is going to have to deal with all of the responsibilities that come with being the King of Atlantis, and simultaneously have to deal with the plot being developed by Dr. Stephen Shin (Randall Park) and Black Manta (Yahya Abdul-Mateen II) as they try to expose the secrets of the underwater kingdom to the world.
We previously learned that David Leslie Johnson-McGoldrick, who was a co-writer on the first Aquaman, is writing the script for Aquaman 2, and while nothing about the plot has been confirmed yet, we can draw some pretty solid conclusions simply based on where the last story left off.
