Kryptonians are a humanoid species that hail from the destroyed planet Krypton. Most that remain have come to try and settle on Earth.


Hundreds of years ago, the Kryptonians fought a bloody war to a stalemate, against the Daxamites.

Thousands of lives were lost on both sides. The actual cause for the war remains unknown, with both sides insisting that the other started it.


Kryptonians came from a planet far from Earth and possessed technology far beyond the technologies of humanity. Their planet however was on the verge of total destruction and only a select few managed to survive Krypton's destruction and either fled to other worlds or were trapped in the Phantom Zone.

The race on Krypton were described as one of explorers, philosophers and scientists. However, some Kryptonians were known for their arrogance and self-righteous attitudes as well as being deceptive and hypocritical showing little to no remorse for their actions and their tendencies on being quick to judge others. Also when Kara's mother Alura used her daughter as a means arrest Astra, she was shown to not feel guilty for this at all as she believed the end justified the means.

Despite some of these negative traits, most kryptonians, such as Kal-El, Kara Zor-El and Astra, are polite, humble, modest and respectful, they also have a sense of justice, honor and good morals to the point of having guilt, shame and remorse for their actions.

Culture and technology

The technology of Kryptonians is known to be thousands of years ahead of anything found on Earth. They have mastered the use of interstellar travel as well as creation of holograms through the use of crystals. Kryptonians were also known to have created portals leading to a dimensional plane known as the Phantom Zone which they used as a prison. Their weapons were also extremely advanced, most likely energy based. The clothing of Krypton's inhabitants has also shown to be as durable as they are and can withstand a great deal of abuse.

When Kryptonians pass, their bodies are sent on a celestial journey with their close loved ones so that they could be received by their sun god Rao. Where on Earth, humans say the term "Thank God", the Kryptonian equivalent is "Thank Rao".

World Killer Prophecy

Kryptonian ancient traditions speak of a malicious being called the destroyer of worlds and was born of the Old Gods .

Physical appearance

Despite hailing from another world, Kryptonians are indistinguishable from humans.

Powers and abilities


  • Longevity: Kryptonians' life spans are considerably longer than normal humans and likewise ages much slower.
  • Solar energy absorption: Under the effects of a yellow or blue sun, Kryptonians absorb and metabolize it's solar radiation, resulting in superhuman abilities.
    • Flight: On Krypton, the gravity was much stronger than that on Earth, so strong that it could kill a human being. On Earth however, gravity is not a boundary for Kryptonians and they can defy it at will, allowing them to levitate and float in the air and move in any direction at various speeds. They are able to fly in any altitude without ill effect, though they stay within Earth's orbit as they need gravity to generate the thrust required to fly and still need to breath.
      • Super leaping: Kryptonians are able to jump several stories in a single bound without having to fly. While they commonly do not use their ability to travel, it is commonly used while a Kryptonian first learns to fly, especially if they are raised on a planet with a yellow or blue star for a large portion of their lives.
    • Invulnerability: Under the effects of either a yellow or blue sun, Kryptonians are virtually impervious to all forms of physical harm and have a higher resistance to pain. Their bodies cannot be penetrated by most outside forces, energies, or chemicals though they can sometimes be enough to cause them pain, weaken them or incapacitate them, especially in great amounts.
      • Self-sustenance: After the Kryptonians are exposed to the effects of a blue or yellow sun for an unknown number of years, the Kryptonians' physical needs will be greatly reduced or completely removed, such as the need for oxygen.
      • Atmospheric adaption: While Kryptonians do require oxygen, their physicality allows them to survive while inhaling more harsh forms of it.
      • Contaminant immunity: Kryptonians are known to have an immunity to any known forms of diseases, ailments and illnesses, along with chemicals and toxins, on Earth. This immunity can extend to similar contaminants or chemicals from most other worlds. Notably, Kryptonians are immune to the effects of alcohol on normal humans, though some alcohol and similar substances from other worlds can affect them as normal alcohol would affect humans.
      • Telepathic immunity: Kryptonians are known to have an immunity to most telepathic powers.
    • Accelerated healing factor: Despite their virtually impenetrable skin, Kryptonians possess a healing factor, giving them the ability to heal and recover far faster than a normal human. Also, their high metabolism allows their bodies process and burn calories far more faster than any other normal human, essentially allowing them maintain a healthy weight and physical condition with little to no maintaining.
    • Heat vision: Kryptonians are known to emit concentrated beams of intense heat energy from their eyes, which comes in the color of plasma blue or cyan. They can also control the temperature and intensity of their heat vision, allowing its uses to range from simply heating liquids, to causing fires and small explosions, to burning through or welding stone or metal. It has also demonstrated being able to physically repel and potentially damage more durable opponents, such as other Kryptonians, sending them flying through the air at great speed.
    • X-ray vision: Kryptonians are capable of seeing through virtually any solid surface, giving them the ability to know what's on the other side of a building, and even see down miles underground. In conjunction with this ability, Kryptonians can see clearly for several miles, allowing them to view events as if they where there from a great distance, such as looking into a flying plane from several stories down or looking into a room from several buildings away.
    • Super breath: The respiratory system of a Kryptonians is similar to human's, yet the only difference is that Kryptonians can take in a great deal of air and expel it with powerful force winds. They can also manipulate the temperature of their to generate subzero cold and use it to either generate ice or freeze a target into ice.
    • Super hearing: On Earth, Kryptonians have the ability to hear things at greater distances and with greater clarity than any human. They can also single out distinctive sounds as well if they are focused enough. In conjunction with their enhanced sight, Kryptonians can clearly hear what is going on in places they are looking into, whether it be from a across a building or several buildings.
    • Super strength: All Kryptonians are known to possess the ability to lift and press an indeterminate amount of weight with similar force, sometimes with little to no effort. With their bare hands, they are able to break stone and metal with their bare hands, to stop moving vehicles, or to send objects and people flying through the air. They can also apply this strength into combat as well, allowing them to easily overpower and restrain people, to break bones with one hand, and to injure or kill humans, as well as some aliens, with as little as one strike. However, a Kryptonian still must physically exert themselves when using their strength to lift, push, or pull objects or structures that are far larger than themselves, such as planes, freighter ships, trains, or even collapsing buildings. They also exert themselves when fighting other superpower beings of similar levels of strength and durability, such as other Kryptonians. This kind of exertion makes them vulnerable to strain, soreness and fatigue, as humans experience when they exert themselves, though they can recover from it much faster than humans can.
    • Super speed: Kryptonians are capable of moving, reacting and flying at speeds rivaling the world's fastest fighter jets and casually break the sound barrier. It is unknown as to whether or not they are capable of moving faster than light. Commonly, they use short bursts of speed to dash several feet in the blink of an eye, causing them to appear as a vibrating blur of motion to others. Many times, they have been able to use their speed to attack their enemy faster than they can counter or evade, as well as to generally catch others off guard by appearing or disappearing before they notice, sometimes when in full view of them.


  • Multilingual: Kryptonians are capable of learning to speak other languages very quickly.


  • Beings of superior strength: Despite their extreme durability, beings of much greater strength can easily bypass their extreme durability to injure or potentially kill them.(This includes other Kryptonians)
  • Extreme energy: Extreme amounts of energy, such as the energy from the Reactron suit or Livewire's electricity, while she is at her peak, can be enough to kill a Kryptonian.
  • Alien technology: Alien weapons and technology, such as Vartox's axe, the Master Jailer armor, or the mind control orb used by the Dominators, can used against them to breach a Kryptonian's invulnerability, and therefore, to potentially harm and kill them.
  • Heat vision: Kryptonians can be burned by heat vision at high intensity, notably if they are overwhelmed by another's heat vision if they are firing it against the each others, resulting in it being able to burn their eyes and blind them.
  • Green Kryptonite: A radioactive piece of the Krypton, Kryptonians exposed to Green Kryptonite will become weakened and dizzy within close proximity or by being pierced by weapons laced with the element. Its radiation removes their invulnerability and leaving them weaker than humans. Green Kryptonite weakens their physical attributes, leaving them vulnerable to weapons and anything in general that can kill a normal human, while mere prolonged exposure can be enough to kill them.
  • Red Kryptonite: Kryptonians exposed to red kryptonite will gradually lose their inhibitions until they are left to be corrupt versions of themselves with all their negative personality traits and thoughts overshadowing them. Left without morality, rationality, or any cares whatsoever, they will become malevolent and prone to hostility and aggression, making them a danger to everyone around them.
  • Silver Kryptonite: Kryptonians, exposed to Silver Kryptonite, it will cause them to go in a deep and frightful hallucination where nothing from the outside world can stir them out of it until it leaves their system. It won't dampen their strength but will make them become a danger to the one that they view as their mental tormentor.
  • Lead: Despite it having no lethal effects on Kryptonians, lead is one element they are incapable of seeing through.
  • Magic: Since Kryptonians get their powers from their heritage they have no more protection from magic than a normal human.
  • High-frequencies: Though considered a strength, a Kryptonian's hearing does have its disadvantages. Since their hearing is more sensitive than a normal human's, higher pitch noises (sonic screams, etc.) can disorient them and cause pain in their ears, leaving them vulnerable in a fight. Therefore, enemies with sound based powers, like Silver Banchee can potentially be powerful enough to cause a Kryptonian's ears to bleed.
  • Sound-dampening technology: The D.E.O. designed frequencies to block super-hearing and cause Kryptonian's slight pain when trying to use it in areas protected by the technology.
  • Red Sun energy: The energy from a red sun is known to be the Kryptonians natural sun and therefore, exposure to it will make them the equivalent of a human being on Earth.
  • Solar energy depletion: Using a power like heat vision to its maximum for an extended period can significantly drain solar energy to the point where a super-powered Kryptonian loses all of his/her powers and is rendered more humans like for at least a day. This renders them as weak as humans, allowing them to get injured and killed as easy as killing an Earth creature.
  • Solar energy overload: If Kryptonians absorbs too much solar energy, it will act as a poison and kill them.
