Celestialsapiens are the native species of a dimension known as the Forge of Creation, and are defined as "Transcendent Aliens".

Biology[edit | edit source]

Anatomy[edit | edit source]

Celestialsapiens are silhouette-like humanoids that can manifest themselves on any size. The insides of their bodies resemble outer space, and they have white star-like dots scattered inside their bodies. Their face consists of white eyes with no pupils and no mouth, although some males can grow beards.

Male Celestialsapiens physically resemble muscular male adult Humans. Females physically resemble thin female adult Humans. Newborn Celestialsapiens are shaped like Human babies.

Celestialsapiens can have either three trident-like horns on their forehead, two horns on each side of their head, or a flaming top resembling hair, though this varies by individual.

Bellicus, Serena, and Ben Tennyson; Alien X's personalities

A Celestialsapien's starred body is not simply "aesthetic". Rather, they contain their own debate dimensions, which exist inside of their own heads.[1]

A Celestialsapien's unique personalities, consisting of a masculine voice of rage and aggression and a feminine voice of love and compassion, are considered to be "sort of" part of their DNA.[1] In the case of Alien X, his voice of rage is named Bellicus and his voice of love is named Serena.

Celestialsapiens originating from different time periods of any timeline are the same, not just genetically but literally.[2]

Diet[edit | edit source]

Celestialsapiens eat "star-stuff".[3]

Reproduction[edit | edit source]

If a female Celestialsapien is pregnant, a white orb containing a developing baby will grow on the palms of her hands. It takes a newborn Celestialsapien thousands of years to develop.[1]

Powers and abilities[edit | edit source]

Celestialsapiens are omnipotent, being able to warp reality, time, and space with ease and at any level they wish. Even their thoughts can become real. In short, Celestialsapiens can do anything. Technically speaking, pure Celestialsapiens are more powerful than hybrid Celestialsapiens[2] and the Contemelia.[3]

Celestialsapiens can create time waves to reverse events on a specific area, such as a destroyed dam.

Celestialsapiens can create universes at will, and recreate a universe that has recently been destroyed.

Celestialsapiens possess superhuman levels of strength, being able to lift and throw a To'kustar.

Celestialsapiens are extremely durable, being able to withstand attacks from Omni-Naut Vaxasaurians and mutant hybrid Petrosapiens.

Celestialsapiens are excellent in hand-to-hand combat. They can also perform self-duplication on an infinite scale.

Celestialsapiens can generate small galaxies to suck in other beings and massive storms. They can also terraform planets with their presence.

because they are born in a place time does not exist they can fly and run at infinite speeds, as they can accelerate the speed of their flight. They can also leave a glowing green trail while flying.

Due to the nature of their existence, Celestialsapiens can survive in the vacuum of space.

Celestialsapiens can alter their size to something larger than a gas giant. With hybrid Celestialsapiens such as Alien V, their maximum size is larger than the average To'kustar.

Celestialsapiens possess telekinesis, which has been effective on Pyronites, Kinecelerans, Tetramands, Aerophibians, Prypiatosian-Bs, and hybrid Terroranchulas.

Celestialsapiens can deflect energy attacks, such as a Prypiatosian-B's radioactive blasts.

Celestialsapiens can bond their power with each other, but only if they collectively agree to do so.

It is possible that Celestialsapiens can travel through the multiverse.[3]

Celestialsapiens can levitate, which is most evident whenever their personalities are debating and the Celestialsapien in question does not do anything.

A Celestialsapien's reality warping is so powerful that the personalities can even prevent their external body from being destroyed just by agreeing that it will not.

Weaknesses[edit | edit source]

Celestialsapiens are left in an inactive state for as long as the personalities are debating amongst themselves. For example, Professor Paradox has spoken of an alternate version of Albedo who transformed into Alien X and was trapped motionless for nearly a year.

Celestialsapiens are vulnerable to having their abilities being absorbed by Osmosians and entities with similar powers like Darkstar.

Celestialsapiens are unable to manipulate Mana directly. They would have to alter the universe to change the nature of Mana first.[4]

Celestialsapiens are vulnerable to being possessed by an Ectonurite.[3]

Celestialsapien personalities are capable of experiencing fear in the presence of Toepick's Species.[3]

A Celestialsapien's actions onto reality can be neutralized and reversed by the intervention of their own brethren.

Celestialsapiens can be affected by a Nemuina's sleeping dust.[3]

Celestialsapiens can be affected by magic, as their powers do not work well against it.[3]


There is a clear limit to a hybrid Celestialsapien's stamina, as they are vulnerable to a To'kustar's cosmic rays and a Chimera Sui Generis' optic beams.

Celestialsapiens can have their life force sucked out by a Vladat. However, they will not receive a cosmic power boost from feeding off a Celetialsapien because they would feel like they just slammed an energy drink.[3]

Celestialsapiens can be eaten by Gourmands, who would either digest them or spit them back out. However, they will not gain the Celestialsapiens' cosmic powers in any form or way.[3]

Because they are not allowed to reach full power, hybrid Celestialsapiens such as Alien V are weaker than they potentially could be.[2]

Despite being unaffected by the destruction of a universe, Celestialsapiens are unable to survive the destruction of the Omniverse unless they were to combine their powers in advance.

Celestialsapiens are only omnipotent in their universe of origin.[4] Therefore, they could be rendered powerless or have their powers limited to basic cosmic laws if they were to set foot in universe other than their own. That can happen because either that universe in question is not in line with the Celestialsapien's internal astronomy or it does not follow their native universe's laws.[3]

Culture and society[edit | edit source]

Celestialsapiens prefer their shrouded existence in a dimension known as the Forge of Creation, as opposed to being involved with the "petty going-ons" of the rest of the universe.

Both of a Celestialsapien's personalities must agree on something for any actions to take place. However, due to their contrasting personalities, this hardly ever happens.[4] When it does happen, it usually takes thousands of years.[1]

Most Celestialsapiens only have two personalities, yet Alien X has three with Ben Tennyson being the "voice of reason". Consequently, two out of three must agree on something in order for Alien X to perform any sort of action.

It is very dangerous to disturb Celestialsapiens while they are debating because, as stated by Kevin Levin to Ben's younger self, "they can just blink, and we'd be gone".

Celestialsapiens do not wear clothes because they mostly spend time naked among themselves. They mostly will follow the rules of galactic social norms whenever they are outside their own space.[3]

Much like their birthplace, Celestialsapiens exist outside of time and space itself. In other words, they are simultaneously everywhere and nowhere at the same time.[2]

Language[edit | edit source]

Whenever a Celestialsapien speaks, both personalities' voices speak in unison. Depending on what the voices agree on, they will say "Seconded!" or "Motion carried!" if they agreed. Instead, they will say "Motion denied!" if they disagreed.

Notes[edit | edit source]

  • The Omnitrix's Celestialsapien representative is named Alien X, who first appeared in the Alien Force episode "X = Ben + 2". Alien X has appeared in almost every subsequent series except the reboot.
    • It has been confirmed that the Ben Tennyson of Dimension 23 does not have an equivalent of Alien X.[3]
    • Nega Ben has an equivalent of Alien X named Apathetic-X.[3]
    • Despite not appearing on-screen, it is confirmed that Ben 10,000[2] and Albedo both have Alien X available in their Omnitrixes.
  • Alien X's existence seems to come into conflict with ordinary Celestialsapiens. Alien X has three personalities, where as ordinary Celestialsapiens only have two. Essentially, Alien X has a voice of reason due to the presence of the transformation's user.
    • An alternate theory behind Alien X's being is that when Myaxx obtained Celestialsapien DNA, she used Galvan technology to remove the original voice of reason, replacing it with the Omnitrix's wearer. Of course, there is currently no evidence confirming or denying that an ordinary Celestialsapien has a voice of reason.
  • The name Celestialsapien is a play on "celestial," meaning from the stars; and "sapient", a term for intelligent.
  • When the Celestialsapiens were introduced in Alien Force, they were not considered to be the most powerful race in the universe.[1] This has been retconned in Ultimate Alien, as it is stated in the episode "The Forge of Creation" that Celestialsapiens possess nigh-unlimited power.
    • Similarly, it was initially stated that Celestialsapiens came from the planet Zvezda.[5] This has been retconned two ways in Ultimate Alien, as Zvezda has been stated to not exist[1] and Celestialsapiens come from the Forge of Creation instead of a planet.
  • Ben has managed to overcome the Celestialsapien's greatest weakness by convincing Bellicus and Serena to give him full control of the form in exchange for letting the two debate with each other in peace.
  • Paradox is not allowed to be within 500 lightyears of a Celestialsapien or else he will be destroyed for ignoring this restraining order.
    • When asked why this restraining order was made, Derrick J. Wyatt believed it was due to excessive unwanted hugging.[3]
  • All Celestialsapiens are born in the Forge of Creation. However, some are found in the Milky Way Galaxy, which would explain how Myaxx obtained a DNA sample for Alien X.[1]
  • It was once stated that Celestialsapiens could destroy a Multiverse, but that would have to require six thoughts. Years later, the statement would be refuted under the impression no one ever said so.[3]
  • At least one Highbreed gained Celestialsapien DNA during their genetic repair. However, he is probably unable to use Celestialsapien powers.[1]
  • In Nega Ben's timeline, the Galvan were wiped out at some point after the creation of his universe's Omnitrix by a rogue Celestialsapien that had been coerced by Maltruant.[3]
  • In 2020, Derrick J. Wyatt released a full-color model of an alternate version of Alien X used by Albedo.
  • It is confirmed that the Omnitrix from the Ben 10 reboot contains Celestialsapien DNA.[2] Therefore, Alien X is one of the countless aliens whose DNA pod was glimpsed in the episode "Innervasion Part 5: High Override".
    • Alien X is among the aliens considered to physically appear in a future season of the reboot. His presence within the show was first hinted during the film Ben 10 Versus the Universe, as Vilgax was able to transform himself into Alien V using Celestialsapien DNA.[2]
