Emperor Aquaman Vol. 4: The Tidal War

Atlantis has fallen, Aquaman’s enemies have united, and the fate of the galaxy hangs in the balance.
The war for the seas has begun.
When Ocean Master, Black Manta, the Crimson Queen, and Aquaman’s deadliest adversaries forge an unprecedented alliance, they set in motion a conflict that threatens far more than Atlantis. As ancient rivalries erupt and kingdoms collide, Aquaman finds himself facing enemies on every front while struggling to protect the empire he has fought to build.
But the battle soon grows beyond the oceans of Earth. With Atlantis under siege, mysterious cosmic forces emerging across the universe, and an ancient power awakening, Aquaman is drawn into a conflict that connects the seas, the stars, and the very foundations of creation itself.
Written by Jeremy Adams and illustrated by John Timms and Paolo Villanelli, Emperor Aquaman Vol. 4: Tidal Wars continues the epic Tidal War storyline with globe-spanning action, cosmic adventure, and high-stakes superhero storytelling.
