The explosion of an underwater volcano creates a giant monster that threatens the safety of the Earth. Aquaman tries to find the location of the monster's underwater lair so he can put a stop to him once and for all.

An inter-dimensional pool of poisonous pink liquid appears on the floor of the ocean. Through it, a monster appears with its sights set on Atlantis. Aquaman and Aqualad must work quickly to protect their home.

A dragon that, instead of breathing fire, has the ability to freeze anything in its path is causing the normally warm waters to become cold. Aquaman and Aqualad, with the help of Tusky, do battle with the dragon and eventually trick it into sealing itself into an iceberg.

Tremors and quakes are causing havoc in the sea. Aqualad is in the area and Aquaman goes to investigate.

Aqualad finds a city built by a super scientific race. The race turns out to be The Octomen. Aqualad and Tusky are kidnapped by them to lure Aquaman into a trap and find out how he communicates with the sea creatures. While saving Aqualad, Aquaman is captured and forced to reveal how he uses his powers. This gives him an opportunity to call his undersea friends for help. At this moment the trap, an electric octo-giant, is unleashed. Aquaman and Aqualad are forced to find a way of destroying the creature.

Tusky discovers an old shipwreck and brings it to the attention of Aquaman and Aqualad. When they arrive at the ship they discover that it has been the hideout for the Torpedoman since his last encounter with Aquaman.

Aquaman goes to investigate strange rising tides and a strong new ocean current. He discovers that there are icebergs that have moved too far South and are melting fast making the water levels rise. He sets off to the North Pole to see if the icecaps are melting.

The domed city of Atlantis is attacked by The Brain, who uses sonic brain waves. Aquaman and Aqualad go to investigate and intercept a missile attack with the help of their fish friends. However, after the sonic brain waves are activated, Aquaman no longer has control over the fish, giving The Brain the perfect opportunity to attack Aquaman.

The Fisherman uses his crab-shaped craft to first set a trap for Aquaman and then to lead an assault on Atlantis.

Three of Aquaman's greatest foes join forces to defeat him. The Brain asks Black Manta and Queen Vassa to combine their genius and simultaneously attack Aquaman and Atlantis.
