Eternity Cosmic Entity
The cosmic entity known as Eternity is the embodiment of the physical totality of the universe. Everything – from the smallest subatomic particle to the largest supercluster of galaxies – is part of Eternity. He is aware of everything that happens in the universe, but most of the time rarely interferes unless the cosmos itself is threatened.
When he manifests – and Eternity always takes on a male form – Eternity appears as a humanoid male with a high-neck cape, whose body is an ever-shifting morass of star fields, galaxies, nebulae, and novae. His manifestations have altered in size from six feet to six miles tall, though most of the time he manifests at 100 feet tall when conversing with manifestations of the other cosmic entities.
It is said that each universe in the multiverse has their own version of Eternity. It is also said that Eternity spans the multiverse. Perhaps both are correct: Each universe in the multiverse is made of separate dimensions, such as the Purple Dimension of Aggamon, the Dark Dimension of Dormammu, the Microverse, the Negative Zone, the Dreamscape, and the Nightmare Realm, to name a few, are all distinct from Earth's universe, but all part of Eternity, while other timelines have their separate Eternity (see Nightmare).
Eternity, along with his sibling Infinity, the embodiment of time, was formed at the creation of the universe. Their interaction led to the Big Bang which triggered the universe's expansion; it also led to the formation of their other sibling, Death, and released one other entity which allegedly predates the collapse of a prior universe, whose nature is currently unrevealed.
Although Eternity generally doesn't bother interacting with the various forms of life that are part of him, it is considered a rite of passage on Earth for its Sorcerer Supreme to seek an audience with Eternity, as to understand Eternity's nature is considered vital for the protection of Earth and the universe from mystic threats. According to the Ancient One, Earth's recently retired Sorcerer Supreme, only thrice in the history of Earth has this audience been granted: to Agamotto, Earth's first Sorcerer Supreme at the start of human history; the Ancient One himself, hundreds of years before at the start of his tenure; and Doctor Stephen Strange, the most recent to attain the position (see Mystic Principalities). The Ancient One indicated to Strange that such an audience "with the universe" has a price, a boon that will later appear as a curse. What form this boon/curse will take with Doctor Strange is unknown.
Eternity, alongside his sibling Infinity, has also seen fit to make his appearance known to Adam Warlock, the current holder of the Infinity Gem known as the Soul Gem, to warn Warlock to ensure one of his allies does not threaten reality. Which ally Eternity and Infinity spoke of is currently unknown, although several of Warlock's other allies suspect the Mad Titan Thanos, who secretly covets the Infinity Gems for his own purposes.

Stats: Don't worry about it. How do you give stats to an entire universe?
Design Notes:
1. Yes, that's a hint of Galactus's existence in there. Galactus himself won't be seen until Year Two.
2. The implication with the the boon/curse is that Agamotto used one of his own eyes to create the Eye of Agamotto, and the Ancient One's extreme longevity is both a blessing and a curse as he's long outlived nearly everyone he's known. I'm not sure what form Strange's boon/curse will be beyond "may you live an interesting life", so I'm keeping it vague for now.
