 The Marvel Universe versions of the gods of the Earthly religions, are not cosmic in the traditional sense, although the strongest of them, such as Atum and Odin, can rival or exceed the power of certain cosmic beings, as can the most powerful demons or independent mystic entities such as Zom, Dormammu, Shuma-Gorath, Mephisto, Chthon, or the Vishanti, and, per extension, the Sorcerer Supreme, Doctor Strange, at times when he channels their full power, but their existence is not necessary for the universe to function.Others pretend to embody existential concepts, but lack the power of the true entities, such as the demon D'Spayre who has claimed to embody despair, but in rare cases, such as Nightmare or Amatsu-Mikaboshi it depends from story to story whether or not they are considered embodiments.Exactly how many true cosmic entities exist is unknown, and more keep being revealed as time passes.
