In the Ultimate Marvel universe, the Celestials are a race of powerful metahumans led by Shen Xorn.  In the alternate reality of the 1998 miniseries Mutant X, the Celestials openly opposed the Goblin Entity, an all powerful being that consumed entire galaxies and the polar opposite of the Phoenix Force .
This begs the query “How many celestials in marvel?”
In the comics, there are 35 known Celestials, so just like with the Eternals, more (if not all) will surely be introduced in the MCU’s near future.
While I was researching we ran into the query “Who are the Celestials in Marvel?”.
The Celestials are a race of unusually large humanoid cosmic entities that appear in the Marvel Universe. They were created by Jack Kirby and debuted in Eternals #2 in 1976 and have been an integral part of the Marvel mythos since then.
When I was researching we ran into the question “Who are the Celestials in Marvel Comics?”.
The Celestials are involved in the creation of new universes, including that of the Prime Marvel Universe. The Celestials visit planets—in what is known as Celestial Hosts—to experiment on, and judge, lower life-forms. They create Eternals and Deviants from selected species.
Another common question is “How powerful is the celestial in the Marvel Cinematic Universe?”.
The comic version of this Celestial was powerful, but he was also killed, making him one of the few Celestials to be truly taken down. However, we’ll be judging the Marvel Cinematic Universe version of this character, since Marvel deemed him significant enough to be the only comic book Celestial to show up on film.
These giant cosmic space gods have been referenced a few times already in the Marvel Cinematic Universe, specifically in the Guardians of the Galaxy movies. With their close ties to the Infinity Stones, there’s a good chance that the Celestials will make an appearance in Avengers 4.
Who are the Celestials?
Celestials are powerful cosmic beings created by the First Firmament. The Celestials rebelled against their creator and Aspirant counterparts in a war that shattered the first universe into the first multiverse. The Celestials are involved in the creation of new universes, including that of the Prime Marvel Universe.
In modern times, however, with the rise of superhumans, many superheroes rediscovered the existence of the Celestials. According to the visions of Kyle Richmond and the Watcher’s equipment, the Celestials came from the same universe as the Elders of the Universe.
The Celestials debuted in The Eternals #1 (July 1976) and were created by writer and artist Jack Kirby. They reappeared as regular guest stars in three subsequent limited series sequels: The Eternals vol.
It has been reported that the Celestials’ 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.  Celestials’ armor can be taken off.
