As depicted in the crossover "Atlantis Attacks", Attuma allied himself with Ghaur and his Deviants and Llyra and her Lemurians against humanity. He battled Iron Man and Namor, and then learned that the superhero Andromeda was his estranged daughter. Attuma mobilized his troops for an assault against the United States. He abducted Marvel Girl as part of Ghaur's plan. Attuma then finally met his daughter Andromeda again, who now led a group of Atlantean rebels against him. Attuma fought his daughter and defeated her in personal combat, but Ghaur spirited her away. Attuma was angered, but continued with their plans. Ghaur and Llyra tricked him though and while Attuma attacked the surface world, battling Spider-Man and the Fantastic Four, Ghaur and Llyra attacked Atlantis and killed a large part of the population as a sacrifice to their god Set. When hearing about Atlantis' destruction, Attuma went into a stupor and the Atlanteans retreated. Attuma was put on trial, but made his way back to Atlantis.
