History: Attuma was born into the tribe of Homo mermanus who eschewed civilization to live as nomadic barbarians. For some unrecorded reason, Attuma was endowed with strength far surpassing that of his people. Nearing adulthood, Attuma learned of a prophesy, in the lost Atlantean Chronicles, of a conqueror who would take the empire of Atlantis by force. Believing he is that conqueror, Attuma has launched numerous attacks on the city of Atlantis and its regent Prince Namor.

Unable to best Namor in personal combat, Attuma has frequently taken allies to further his ambitions. These alliances have also met with defeat. The first time Attuma attacked Atlantis, the Fantastic Four aided Namor in repulsing his attack. In recent years, Attuma has battled the Avengers as well. Not renowned for his intelligence, Attuma has frequently employed renegade Atlantean and human scientists. One of them created the Octo-Meks, octopus-shaped fighting machines. Another proposed that he mate with human mutants inorder to produce a sire stronger than Namor himself. Toward this end he abducted the mutant Phoenix, but she thwarted his plans. Although Attuma has never been able to claim a lasting victor over Namor, he was a party to the death of Namor's bride, lady Dorma. Attuma is still at large in the Atlantic Ocean, having never been imprisoned for any of his deeds.

Strength Level: Attuma possesses superhuman strength enabling him to lift (press) approximately 40 tons on land, and somewhat more than that in his native element, the sea. Attuma is significantly stronger than the average member of Homo mermanus.

Known Superhuman Powers: Attuma possesses the typical attributes of Homo mermanus: gills to enable him to extract oxygen from the water, superhuman physiology to enable him to withstand the extreme water pressure changes beneath the sea, blood circulation enabling him to withstand freezing temperatures, and specially-developed vision which is more sensitive to the green portion of the spectrum enabling him to see in the murky depths.

Attuma is far stronger that the typical Atlantean. Whereas most Atlanteans can swim at a speed of 30 mile per hour, Attuma can swim at 60 mile per hour. Like all Atlanteans, Attuma cannot breathe air out of water. He is capable of lasting approximately ten minutes out of water before he begins to suffocate.

Doctor Lemuel Dorcas once altered Attuma in some unknown way so that he could breathe on land, it is unknown whether or not this alteration is still effective.

Weapons: Attuma customarily carries a three-pronged iron sword weighing approximately 50 pounds.
