Arishem the Judge

Within Marvel's fictional cosmology Arishem is one of the Celestials, originally associated with the First Firmament and appearing as an original Celestial in early cosmic eras. The Celestials operate across multiple cosmic iterations; Arishem functions as a long-lived adjudicative agent who participates in cycles of cosmic death and rebirth, creation of species, and large-scale judgments of civilizations.

Sources describe Arishem as an immense member of the Celestials — towering, cosmic beings of vast scale and durability. Specific visual detail in the provided texts is limited beyond repeatedly identifying him as a Celestial 'immense' being who leads Celestial hosts; he also appears in the Marvel Cinematic Universe film Eternals (2021).

Arishem is described as an extremely powerful cosmic being whose powers transcend time and space. He can manipulate cosmic energies, create new species, and eradicate life; he has acted to cull populations (for example, involvement in the Deviants' reduction and events termed the Great Cataclysm). Like other Celestials, Arishem is nigh-invulnerable and nigh-immortal and can regenerate lost limbs 'instantly.' Celestials exist across the multiverse at once—'there is only one Arishem in the multiverse, but he is split among aspects in every universe'—and fallen Celestials can be resurrected by others if they have not been dead 'for too long.' Arishem leads Celestial landing parties and has led all Four Celestial Hosts on Earth; in narrative episodes he has undertaken long-term judgments such as a fifty-year judgment of Earth.
