Fan Casting Aquaman III (2029)

Aquaman still rules Atlantis, and is doing a rather impressive job doing so, especially after the events of the last movie. But now, when everything is okay and comfortable, a new mysterious villain from the depths of Atlantis comes after Aquaman after he has been proclaimed the leader of the Secret Sea. Aquaman must defend his home, the sea, and his loved ones from the mystical beast, and this time, he might not have the certain morale that is needed for something of this magnitude. But with this, he might need a little help.
