Zuras first appeared in The Eternals #5, and was created by Jack Kirby. Marvel Comics continuity was later retconned so that the character presented as the mythologicalgodJupiter, introduced in Red Raven Comics #1, was, in fact, Zuras.
Zuras was born in Titanos, first city of the Eternals, and is the son of the Eternals Kronos and Daina, and brother of A'Lars. With his wife Cybele, he has a daughter Thena. Zuras was a warrior, and vied with his brother A'lars for leadership of the Eternals of Titanos following Kronos' death. Zuras was the first Eternal to form a Uni-Mind by creating the first ritual of the Uni-Mind, and was therefore chosen to become leader of the Eternals of Earth. He was mistaken for the Greek godZeus many times in the past, and ultimately forged a pact with Zeus to keep their people at peace. When Kro spread chaos in the 1940s, Zuras sent Makkari to oppose him. He also forced the Forgotten One into exile, stripped him of his name, and forbade the Eternals from communicating with him. Zuras appears to have been well-traveled, since his quarters in Olympia were decorated with a jukebox, two six-shooters and battle-axes. Zuras authorized Thena to resume her battles against the Deviants, and ordered her and Makkari to battle against Zakka in New York. He also aided Mr. Bradford, a government agent, in studying the Celestials. Zuras attempted to mind-probe the Celestial craft, and learned of the coming of the Fourth Celestial Host. He initiated the first Uni-Mind fusion of Eternals in modern times to attempt to communicate with Arishem. He ended the Uni-Mind fusion, and traveled to New York City and addressed the public on the subject of the Celestial host on a television broadcast. He explored the tomb of Dromedan the Brain-Snatcher, and battled Dromedan. He then assisted the U.S. State Department in the investigation of the Celestial threat. Zuras later encountered Thor. Zuras initiated a second Uni-Mind fusion to prove the Celestial mothership, and battled Zeus. Zuras then allied himself with Odin and initiated the third Uni-Mind to combat the Fourth Host of Celestials in Peru. While fused with the Eternals in the Uni-Mind formation, Zuras attacked the Fourth Celestial host. The Uni-Mind was blown apart by a cosmic blast from the Celestials Gammenon and Jemiah, causing it to disintegrate into its component Eternals, and the backlash caused Zuras's brain death. Even then, Zuras' spirit continued to exist within his body, until his body was finally destroyed by freeing Thena from a Brain-Mine, at which point Zuras's spirit left his body. Zuras's spirit still seems to exist, as it has appeared at times within Olympia, such as when Ikaris challenged Thena for the title of Prime Eternal.
Rewritten
stated that he used the machineries of Olympia to partially "reactivate" Zuras—and then deceived Zuras into visiting the tomb of the Dreaming Celestial, forming a Uni-Mind there. This provided Sprite with the power he needed to rewrite some aspects of reality, stripping the other Eternals of their powers and memories. Sprite also stated that he considered Zuras to be the most powerful of the Eternals. In the "rewritten" world, Zuras was made into an alcoholic homeless man, with mental problems. He was, however, restored by Ajak. Ultimately, Zuras found Sprite after the events were resolved, and killed him by snapping Sprite's neck.
Powers and abilities
Zuras has achieved above average development of the normal attributes of the race of Eternals through great discipline. He possesses superhuman strength, speed, stamina, and durability, and can fly at supersonic speeds. Zuras possesses the ability to manipulate cosmic energy to augment his life force granting him great longevity and regenerative abilities, the projection of concussive force, heat and electrical energy up to a maximum range of 300 feet. He could also use cosmic energy to create force shields around himself, to levitate himself and/or others, and to psionically manipulate molecules so as to transform an object's shape. During his lifetime, Zuras was the only Eternal known capable of initiating the creation of the Uni-Mind by himself. Zuras is also capable of telepathy, illusion-casting, and limited teleportation. Zuras possesses extensive knowledge of ancient and arcane wisdom.
