The Second Cosmos is the personified manifestation of the first Multiverse and second iteration of the cosmos to ever exist. The cosmos go through a cyclical pattern of rebirth from the previous cosmos, life, and then death, after which they pass on to the ethereal location known as the Far Shore. The Second Cosmos was born from the shattered pieces of the First Cosmos, and the Second Cosmos was replaced by the Third Cosmos after its death.
The embodiment of the Second Cosmos and the first Multiverse to ever exist. He was born from the shattered pieces of the First Firmament, personification of the very first universe, during the final moments of the Celestial War.
When the Multiverse passed through its renewal cycle (a recurrent process in which the Multiverse dies and is reborn in a new embodied form), the embodiment of the Second Cosmos went to the ethereal location known as the Far Shore, giving way for a new personification of the Multiverse to rise in his place.
During the Eternity War, he was summoned alongside his successors by Eternity to thwart the plans of the First Firmament, who sought to reclaim his position as everything that is. After the First Firmament was restrained, the cosmoses took him to the Next Place, where they planned to heal him.
- Even though this Multiverse is not given a name, it's referred to as the "Second Cosmos" in Ultimates 2 (Vol. 2) #6 and again in Ultimates 2 #100.
- He is the originator of the Omega Force.
- It is believed that Vibranium was born as a result of his death.
