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.
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.
