Shortly afterwards, Attuma briefly lost control of Atlantis and Namor returned to the throne, but Attuma regained the throne of Atlantis, when Namor was cursed as one of the Defenders, a curse which would transport Namor away whenever the Defenders were needed and leave Atlantis undefended. Attuma formed the group "Deep Six" (consisting of Nagala, Orka, Piranha, Sea Urchin, Tiger Shark) to defend Atlantis from Namor and the Defenders. Attuma's "Deep Six" was named after the first Deep Six, a group of heroes who aided Namor, including Andromeda. Though outnumbered, the Defenders outsmarted Attuma and Namor retook Atlantis.
