The Celestials

Origins
The Celestials are a species of powerful extraterrestrial cosmic beings. This alien race influenced key events in human history for mysterious and unclear reasons. They were responsible for key human evolutionary events, such as the genetic-offshoot races the Eternals and the Deviants[8] as well as the emergence of super-humans both through the inclusion of the X-Gene and through beneficial mutation.However, as old and as enigmatic as the Celestial race is, many myths have appeared around the Universe in attempts to describe the Space Gods.

Appearance
The Celestials usually resemble massive male--or sexless--humanoids of enormous size, with most of them standing two thousand feet (600 meters) in height and some even larger (Exitar stands over 20,000 feet high).Each varies in color and design, which is very elaborate in some individuals. Each has one head, two arms & two legs, indistinct features on their "helmets" sometimes exhibiting two eyes, sometimes more, sometimes none. The "designs" on their armor are of a practical nature and each serves a function of one kind or another- Arsheim's formula of judgement on it's thumb for example. Many, but not all, also have great equipment on their backs or carry great staffs capable of breaking down and reconstructing all forms of energy & matter or lay waste of entire continents. It has been reported that the Celestial' bodies are modular, made up of thousands of varied objects and beings. It has also been reported that they may combine to create larger more powerful amalgams and can animate severed limbs and even their computer ware is sentient.

Powers
Vast Cosmic Powers with no known upper limit. Armor able to withstand planet shattering impacts with ease. A single host has the power to threaten all the pantheons of gods in a planet. In fact, a single Celestial possesses the power to withstand attacks from three Skyfathers at the same time completely unfazed (including Odin and Zeus). [51] Though not a feat of raw power but of durability, it still suggests that a Celestial is far more powerful than a Skyfather.
