The Celestials were an ancient race of armored, humanoid beings with god-like powers. They were present long before the dawn of the galactic communities and even the Dark Elves and Asgardians. They were notorious for using the Infinity Stones.
The origin and nature of the Celestials is shrouded in mystery. Whatever was known about them is known only to a few, such as Taneleer Tivan. The Celestials used the Power Stone as a means of execution against those who wronged them. Knowhere, a spaceborne mining colony, is actually the severed head of a deceased Celestial.
Ego's SchemesTo be added.
The Celestials are primordial gigantic humanoid beings, even predating the dawn of the Asgardians and the Dark Elves themselves. While the most that have ever been seen of a Celestial are severed extremities and a video from the Collector, the clip shows them as armored, humanoid giants. A Celestial, Ego, has displayed a number of superhuman abilities. Ego was capable of manipulating matter and energy at will. Ego is also biologically immortal and unkillable as long as the "Light of his Planet" was alive. As the Collector explained, their physical constitution is so immeasurably strong that they can allegedly wield the Infinity Stones.
- In the comics, the Celestials were deeply involved in humanity's early development, and were responsible for the creation of the mutant X-gene, the Deviants and the Eternals.
