Ajak is a member of the Polar Eternals, a band of the near-immortal
Eternals based in the
Ural Mountains of Russia. Ajak's earliest known interactions with humanity occurred in
Babylon around 2500 BC, when he was among the Eternals who clashed with the
Deviants and their leader
Kro. Around 1200 BC, Ajak and his brother Arex were active in Greece, where they were known respectively as
Ajax the Greater and
Ajax the Lesser. Around 1000 AD, Ajak lived in
Peru, where he assumed the identity of Tecumotzin and
Quetzalcōātl. Ajak acted as a mediator with the
Celestials when they visited Earth. After the Celestials departed, Ajak placed himself into suspended animation along with his assistants. The Celestials ultimately judge in Earth's favor and leave. Ajak and the Eternals leave Earth; during their absence, Damian's daughter Margo is killed by the Deviants. Blaming the Eternals and Deviants for Margo's death, Damian uses Celestial technology to transform Ajak into a monster and sends him to kill
Donald and Deborah Ritter, the children of Kro and
Thena. Ajak is subsequently killed in the confrontation with the Skrull God
Kly'bn.
Death Later, when the Celestials' Final Host arrived on Earth, Ajak, along with all the Eternals, killed themselves after realizing the true purpose for which they were created. Ajak and the other Eternals are later resurrected simultaneously. ==Powers and abilities==
