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

Eon was created by Jim Starlin, and first appeared in Captain Marvel #28 (Sept 1973) to proclaim Mar-Vell as the Protector of the Universe. He later appeared in the Quasar series to appoint Quasar as his new champion, advising Quasar throughout the series.

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.

Eon has not been a contender in any CBUB matches.
