He is a nearly all-powerful and immortal being, capable of manipulating reality and space-time to achieve his purposes. His personality is complex, as he does not have a physical body and manifests himself through the laws of the universe, but he can adopt avatars or possess mortal beings to interact with the world.

Physiology of the Cosmic Entity: Eternity is a very powerful cosmic entity that has existed since the beginning of the universe, possibly even before. It is the timeless representation of the universe and has unlimited control over reality.
Immortality: As Eternity is timeless, the passage of time does not affect it, that is, it does not age.
Near Omnipotence: As the embodiment of the universe itself, Eternity has near-limitless power over the universe, second only to The Living Tribunal.
Wish Granting: Eternity is able to grant any wish to anyone without limitations.
Resurrection: Eternity is capable of resurrecting the dead. When Gorr wished for his daughter to come back to life, Eternity brought her back.
Power Granting: Eternity is capable of granting powers to anyone. When Amor was resurrected by Eternity at Gorr's request, Eternity granted her godlike cosmic powers.
Near omniscience: As the embodiment of time itself, Eternity knows everything that has happened and is happening now.
Near omnipresence: As the embodiment of space-time itself, Eternity is everywhere at once. Eternity is only truly omnipresent in its immaterial form; if it materializes, it will lose its omnipresence.

The walls of the Temple Vault on Morag depicted the four entities that created the Infinity Stones: Entropy, Infinity, Death, and Eternity.

An altar, described as a "universal wishing well," exists in a dimension of the Multiverse that leads directly to Eternity, and whoever manages to reach it first will be granted one wish.
