Origin
One Above All is the leader of The Celestials and is the most powerful member of their race. While not much is known about him, One Above All has been depicted as being far more emotional than the other Celestials, as he has been seen openly displaying fear, hate and sorrow.
While the reasons for his unique emotional state of being are unknown; it is possible that because One Above All spends almost all of his time on The Celestial Mothership, that he could be suffering from the Celestial equivalent of Cabin Fever. Encounters with One Above All are rare, though he has been seen by other denizens of the Marvel Universe, including the original X-Factor line-up. One Above All is also a member of the Living Tribunal’s court where he and Ziran the Tester represent their people.
Creation
The Celestial One Above All is a Marvel comics book character created by writer and artist Jack Kirby, first appearing in The Eternals #7 released in 1977.
Powers and Abilities
One Above All like many of the Celestials is an extremely powerful, god-like being; possessing incalculable levels of strength, durability, speed and energy projection. The One Above All holds special authority and power over the majority of the Celestials. Enormous in stature, up to 2000 feet in height; he possesses the ability to manipulate reality, control energy, and rearrange matter. He can teleport himself or vast objects across vast distances. Although near invulnerable, in the rare case of being injured or harmed; like all Celestials, One Above All will regenerate near instantaneously. Capable of withstanding earth shattering blows, and easily dismissing nuclear bomb offense attacks, the One Above All also possesses the ability to generate energy blasts that are of an earth shattering level and higher. There is an unknown connection between the Celestials and Hyperspace. It is possible that Hyperspace is the origin of the Celestials vast powers. One Above All oversees and leads the Celestials, hence his title and name.
