Green Martians are an alien species from the planet Mars.


The Green Martians live peacefully on the planet Mars. They have battled in a war before. However, one day, they were outmatched by the White Martians, as they were apparently all wiped out, leaving J'onn J'onzz as the last of his kind; however, it was later revealed by M'gann M'orzz, that the Green Martians were not all wiped out, they were turned into White Martians. It is revealed later on that M'yrnn J'onzz was kept alive by the White Martians due to his position as high religious leader of the Green Martians.

Green Martians lived on Mars until they were apparently exterminated by the White Martians, leaving J'onn J'onzz and his father M'yrnn J'onzz the only known surviving members of their species.[1][2]

Green Martians are very peaceful, gentle, kind, caring and selfless, however, they can be cold, cruel, aggressive, violent and ruthless if they are threatened, if the situation calls for it; despite this, green martians are polite, respectful, calm, level-headed and patient, they also have a sense of justice, honor and good morals.

Physical appearance

Green Martians are roughly humanoid, but with a differently shaped head, green skin and red eyes.

Powers and abilities


  • Most Green Martians have abilities that are not possessed by normal humans. These include;
    • Extended longevity: The life spans of all Green Martians are considerably longer than normal humans and they age much slower, allowing them to live for centuries.
    • Super strength: All Green Martians are stronger than humans, as well as some aliens, though not as strong as a fully-powered Kryptonian. They can augment their strength by focusing their telekinesis in their body and use it in a tactile way.
    • Super Speed: Green Martians are capable of moving at speeds that are similar to that of Kryptonians. They can move at speeds that make them invisible to humans.
    • Invulnerability: Green Martians' bodies are denser than a human's but not nearly as durable as a Kryptonian.
    • Shapeshifting: Green Martians are able transform into any living organism, android or creature. A higher level of training is required to shape-shift into forms that are very different from a Green Martian's natural form.
      • Malleability: Green Martians can stretch and bend their bodies and limbs. (E.g. into large whips to grab things at great distance).
      • Accelerated healing factor: Due to their shape-shifting powers, Green Martians heal and recover faster than humans would, to the point of regenerating from damage in minutes.
    • Camouflage: Green Martians can blend in within the environment by changing the appearance of their form and bending light waves around them to match with their surroundings making themselves almost - but not completely invisible. their chances of staying undetected are diminished if they are moving.
    • Density-shifting: Green Martians are able to phase through solid objects or to increase their density to become near-invulnerable. This is an advanced technique not innately possessed by all Green Martians and it requires a considerable amount of training to master.
    • Telepathy: On Mars, all Green Martians can use telepathy to communicate and are able to sense others of their kind when a Martian's psychic abilities are used.
    • Telekinesis: Green Martians can manipulate, move and control objects with their minds and without physical contact. They can use focused telekinesis to increase the kinetic force released from their physical strikes.
      • Flight: By telekinetically moving themselves, Green Martians can simulate flight.
    • Immunity: Green Martians are immune to human diseases and illnesses.
    • Bio-clothing: Another aspect of their shape shifting is their clothes, that are generated as part of their physical bodies.


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


  • Fire: If they are shape-shifting, any part of their body that comes close enough to touch fire partially transform back into its true form, which could be used to expose them. When Green Martians are exposed to fire, their skin turns green.
  • White Martian blood: If the White Martians' blood is injected into the Green Martians' blood system; it will turn the latter into White Martians.
  • Za-alet: Translated as "decay of memory", this is a brain disease similar to dementia. It appears that eldery Green Martians have a small chance to develop this disease (it was implied that this is very rare).
  • Psychic dampers: Those devices can prevent Green Martians from using their mental powers.
