Eon is one of the fictional cosmic entities in Marvel Comics' universe.

Biography

Eon's history stretches back into the universe's infancy; he is the offspring of Eternity and Infinity and the Celestial Axis. He was born eight billion years ago. Charged with protecting the Celestial Axis (the pattern of life energy threading through the universe), and Time, although it often chooses to observe our reality while removed in a dimension called 'The Mists of Time'.

Eon's third function is nurturing the evolution of sentient life of the universe and to maintain conditions favorable to life in the universe. This led to Eon searching out and appointing a being to be his champion, the protector of life in the universe, anticipating and conquering major threats to life. The full details of these appointments, including criteria, line of succession, and past champions, have yet to be fully revealed. The first known champion, Glakandar, was appointed 5 billion years ago. At the same time, Eon also created the quantum-bands, weapons that would enable his champions to wield massive amounts of energy.

In more recent times, Eon appointed Captain Mar-Vell of the alien race, Kree, to be his champion as the Protector of the Universe — the only one to do so without the quantum-bands. Eon granted Mar-Vell "cosmic awareness" to better combat the champion of Death, Thanos. Eon mostly left Mar-Vell to his own devices, but appeared to him at least once, to warn him of an alien threat to Earth.



After Mar-Vell's death, Eon appointed Quasar as his champion, the new Protector of the Universe, and sent one of his pseudopods to Earth with Quasar. Eon made a doorway to his pocket dimension in Quasar's business office. Eon befriended Quasar's father, Gilbert Vaughn. When Eon discovered Gilbert Vaughn's death, he determined to keep knowledge of it from Quasar. Eon was later visited by Moondragon. Eon reanimated Gilbert Vaughn, but had a falling out with Quasar when Quasar discovered the deception regarding his father's death.

It was soon revealed that Quasar was chosen specifically to combat an unknown threat to Eon's self and the universe. The threat was Maelstrom, who assumed the aspect of Anomaly. When Eon was attacked by Maelstrom, Eon bade Quasar to kill him so that Maelstrom would not wrest the secret of cosmic awareness from him. Quasar blasted a hole in the most vital part of Eon's brain. A funeral was then held for Eon by the Mourners. The service was interrupted by Thanos, who used the Infinity Gauntlet to turn Eon's body inside out and squeezed it through all of its portals into this universe. Eon's still animated body was opposed by various Earth heroes. During the fight, Eon's offspring, Epoch, was delivered from its dying womb by Quasar. Quasar promises to watch over her as she grows.

Eon appears to still exist in some form within another dimension.
