Warrior of Atlantis
Lady Zartra was once the most trusted advisor to the Atlantean warlord Attuma.
After the break-up of the Cabal, Zartra switched sides and joined the resistance movement against Attuma. She sent one of her soldiers to the surface world to buy the Serpent Crown from Hydra so she could take control of Giganto and overthrow Attuma.
The Avengers initially opposed her, but after discovering her intentions, helped her into defeating Attuma. In the end, Zartra decided the Serpent Crown was too powerful for anyone, and threw it to the depths of the ocean, even though it was later secretly recovered by Hawkeye.
Powers and abilities
Atlantean Abilities: Zartra possesses the conventional attributes of Homo mermanus: gills that extract oxygen from water, superhuman physiology to withstand extreme pressures and temperatures, and acute vision. She can swim at approximately 30 miles per hour. She can remain out of water for approximately nine minutes before beginning to suffocate. However, she can operate on the surface by wearing a water-filled helmet or using a chemical that enables her to draw oxygen from the air.
