The Martian Manhunter, known as J'onn J'onzz to his friends, is an extraterrestrial immigrant to Earth and the last survivor of the ancient civilization of Mars. Both a philosopher and a guardian, he uses his skills to defend his adopted planet from all threats, equally at home operating in the shadows as the spotlight.

Background[edit | edit source]


"J'onn J'onzz ("Light to the Light" in Martian) was born on the planet Mars (known then as Ma'lecaandra) thousands of years ago. His people, the Green Martians, were one of the oldest races in the universe, rivaled only by the warlike White Martians who shared their planet, and allies of both the Guardians of the Universe and the race that would become known as the New Gods.

J'onn's life on Mars was shaped by Martian principles. Like all in his society, he fulfilled dual roles. In one, he was a philosopher and family man, deeply devoted to his wife M'yri'ah and his daughter Kh'ym. In the other, he was a member of the Manhunters of Mars, his people's police force. He lived by the code of "Once begun, to walk the path, to pursue the prey, to never turn aside, short of death, until justice is done."

The destruction of Martian culture is attributed directly to J'onn's brother, Ma'alefa'ak ("Darkness in the Heart"), who was born a mutant and unable to access the innate telepathic abilities of all Martians. Over the years, Ma'alefa'ak became bitter and destructive, despising Martian society. At last, he attempted complete genocide of the Green Martian race through a telepathically contagious virus, H'ronmeer's Curse. This virus destroyed the entire Martian civilization, killing thousands of Green Martians whenever they used their telepathic abilities. J'onn's wife and child were among the death toll, and J'onn broke down.

Alone and grieving, J'onn wandered the face of his ruined planet for centuries, kept alive by his now-unique Martian physiology. It wasn't until an Earth scientist named Erdel made a spectacular breathrough that J'onn was able to move past his grief. He found himself accidentally teleported through space and time to Earth, long after his civilization was forgotten.

As a peace officer and philosopher, J'onn made the decision to help defend his new home from evil, hoping to never witness the death of another civilization. His natural Martian abilities were considered superpowers on Earth, placing him far above the average earthling, and J'onn felt compelled to use that power to protect and serve.

Using his powers, J'onn established various identities around the world in order to learn more about his new people. Decades later, the debut and widespread acceptance of heroes like Superman led J'onn to believe that Earth was ready to know about their other alien visitor and he went public as the Martian Manhunter.

Personality[edit | edit source]


J’onn J’onzz is at heart a peaceful man. Despite a life filled with tragedy and conflict, he longs for a home where he can simply rest and enjoy life. However, this is balanced with a strong sense of duty and an immaculate moral compass that drives him to defend the innocent, pursue justice, and live up to the ideals he holds dear. As the last survivor of a great culture who witnessed its fall, he is very attached to the institutions and cultures of his new home.

On Earth, J'onn is an eternal outsider, and can be strangely objective in even the most unusual or emotional situations. He is not human, was not raised as a human, and although he often walks in human form, does not wish to be human. As much as he loves humanity, he is and will always be the Last Son of Mars.

Although Mars always holds a special place in his heart, J’onn has truly come to love the Earth and its peoples, and remains one of its staunchest defenders. He approaches life with a calm detachment that masks his care and empathy, and uses rational analysis and logic in the course of his duties. As one of the most powerful beings on the Earth, he holds himself to rigid standards concerning the use of his power, though his standards are not precisely those of Earth.

Powers[edit | edit source]

The Martian Manhunter possess a wide array of varied superhuman powers, which stem from his alien physiology. He has been referred to as the “Swiss Army Knife of Superheroes.” Most, if not all, of his powers are common to all members of the functionally-extinct Green Martian race, although J'onn has been mentioned as one of the most powerful even among his own people.

Shapeshifting[edit | edit source]

  • Shapeshifting: J’onn has vast shape shifting abilities that stem from complete control of his molecular structure. He is able to take on any shape he pleases, often taking the human guise of Detective John Jones. He can form shapes of objects or organisms alive, extinct, or imagined, and he has often shown to grow an extra pair of arms to supplement his fighting abilities and his strength. He can become as stiff and unmovable or as flexible and malleable as he pleases. He can also alter his size or the size and length of his limbs. During his fight with Antares, J'onn grew to the size of building. When increasing his size, J'onn often borrows mass from matter around him and incorporates it in his body, expelling it when he returns to his normal size. The Manhunter has even shown to use his shape shifting powers offensively. He has elongated parts of himself into bladed weapons during combat. His shape shifting abilities extend beyond even that allowing himself to change his chemical composition. He was able to turn his skin into a thick exoskeleton of human bone in order to shield him from a corrosive that would normally disintegrate his Martian physiology.
  • Density Control: His density is also variable and changes as he wills it. He can use this ability to become intangible and move through objects or allow attacks to fly by harmlessly through him or to become extremely dense to add more mass to his blows and increase his invulnerability. J'onn's control over his own molecular structure also allow him to adapt his visibility, granting him the ability to become invisible at will.
  1. Invisibility: He can also become completely invisible to normal sight by forcing his body to stop reflecting light. If he concentrates, he can become invisible to the entire electromagnetic spectrum. This invisibility affects only various forms of vision, so he can still be detected through other senses.
  2. Intangibility: By greatly lowering the density of his own mass, J'onn is able to become intangible. He has used this power often during combat to protect himself from his enemy's attacks and to pass through walls and other structures to travel.

Enhanced Attributes[edit | edit source]

  • Super Strength: J’onn is one of the strongest beings on the planet, able to lift well over 100 tons without much effort through his natural physiology with augmentation from innate psionic and tactile telekinetic abilities. This allows him to lift immense weights without them crumbling under stress. He is easily a peer of the likes of Superman and Captain Marvel when augmenting his strength to his full capabilities.
  • Invulnerability: With the exception of fire, J’onn is virtually immune to physical damage on a level par with a Kryptonian. He can easily absorb kinetic energy with his malleable form, and can harden his bio-polymers to increase his durability to nigh-invulnerability. He does not suffer from hazardous environmental effects (again, except for fire) and is immune to all known human diseases.
  1. Regeneration: He also possesses regenerative abilities that allow him to completely regenerate from nothing but a severed hand or a puddle of green liquids, and survive being decapitated
  2. Endurance: Likewise, he possesses superhuman endurance, and is able to operate under extreme conditions for indeterminate periods of time without showing signs of fatigue. His metabolism is self-sufficient, so he does not need to eat, drink or respirate, and his body produces no waste.
  1. Longevity: Whether J’onn truly ages or not is unknown, but he is centuries old at the least, and has shown no signs of weakening over time.
  • Martian Senses: J'onn possesses nine senses, which gives him more numerable and clearer perceptions.

Psionic Abilities[edit | edit source]

  • Telepathy: The Martian Manhunter is one of the most powerful telepathic beings in the universe. He is able to read the mind of any human without difficulty, even into their subconscious. He has been known to scan the mind of every person on Earth within moments, can read minds from as far away as the moon, and can attune to an unknown number of people at once. The minds of the insane give J’onn trouble, and he has difficulty making sense of their thoughts. He possess a wide array of telepathic tricks, and virtually no aspect of the power is unavailable to him. He can create psychic illusions, control or possess the minds of others, scan or wipe minds, astrally project himself, shield his own mind or that of others from other telepaths, download information into people’s brains, track people by sensing their thoughts and telepathic residue, act as a telepathic relay coordinating a team of people, and even telepathically assault others by causing them to mentally shut down.
  1. Mayavana: A special talent that falls under his telepathy, it is the ability to reach into another mind and create a mental reality as real as any normal reality. It can only be used once in a lifetime.
  • Telekinesis: J'onn can manipulate and move objects with his mind.
  1. Flight: J’onn possesses an innate ability to flie by the manipulation of gravitons, electromagnetic fields, and his psionic control over his molecular movement. He can fly great distances at high speed with little effort. While in atmosphere, he caps his speed at Mach 10 to avoid environmental damage, but he can achieve escape velocity on his own power and can fly in space without difficulty, where he can fly at greater speeds and keep up with the likes of Superman.
  • Martian Vision: J'onn can fire a bolt of telekinetic force from his eyes and cause considerable damage at range. The destructive capabilities of this optic blast have been measured at far greater than 1000lbs of TNT. The full range is unknown, but he has been seen to use it effectively at more than 1000 feet. He can increase the power of his Martian Vision to levels that would even injure the likes of Superman.

Skills[edit | edit source]

Detective[edit | edit source]

J'onn is not quite on par with the Batman when it comes to prowess as a detective, but he scores quite favorably compared to the average PD investigator. He has intentionally honed his detective skills, and maintains his level of mastery through constant use of his talent. He is extremely intelligent, with advanced reasoning and logic capabilities that he can apply to the situation. He is also able to utilize his various superpowers in the course of detective work, giving him much greater resources than any human detective.

Diplomat[edit | edit source]

Despite J'onn's eternal 'outsider' status, he has worked hard to overcome the natural emotional gulf between him and humanity at large. Due to this diligence, he is noted as an excellent mediator and diplomat, with good human relations skills when he applies himself. He is helped in this by his natural telepathic powers and attunement to emotions, granting him exceptional empathic abilities.

Omni-Lingual[edit | edit source]

Due to J'onn's telepathic abilities, he is multi-lingual and fluent in virtually every Earth language. J'onn is a true international hero, and spends a good portion of his superhero career outside America. In the Southern Hemisphere, he is more well-known than Superman, due to this. He has only to be exposed to someone fluent in a language and he can copy that fluency.

Boons[edit | edit source]

Kuru Pendant[edit | edit source]

J'onn is in possession of a Kuru pendant, which acts as a repository of all Martian culture and lore. Using telepathy, a Martian can use the pendant to access the store of knowledge. This includes Martian cultural practices, history, and technological achievements.

Ancestral Memories[edit | edit source]

As part of his Manhunter training on Mars, J'onn was telepathically imbued with the memories of the greatest Manhunters from Martian history. J'onn's memories thus effectively stretch back much further than his actual lifespan, although most of these concern Martian history that is no longer relevant on an interplanetary scale.

Identities & Contacts[edit | edit source]

J'onn has many contacts and unwitting allies throughout the world. Due to the benefits of his shapeshifting and telepathic prowess, and out of a desire to grow closer to humanity, sometimes J'onn takes on a mortal identity. These personas have been of various ethnicities, genders, and nationalities, but they have allowed J'onn to amass a vast number of contacts in various fields related to law enforcement and charity work, though most of them have no idea of J'onn's true identity.

Secret Identities[edit | edit source]


Unlike many superheroes, J’onn was not born on earth and his superhero persona is his true identity. However, in order to more fully understand his adopted people, he takes on various identities around the world and walks among humans in secret. He has, at one time or another, been of all races and genders, across all inhabited continents. While some are of J’onn’s creation, usually conceived for a specific purpose, the others are all people who died before their time, whose lives J’onn slips into and lives out part-time to honor their memory. These are a few of his more useful:

  • John Jones: a private detective in New York, renowned for his accurate hunches; human with no known metahuman abilities, rumored by close acquaintances to be a telepath.
  • Big Doof: a bumbling, harmless supervillain that is the most common cause of his companions getting caught; metahuman with superhuman strength and durability.
  • Josh: an African-American teenager; a known mutant with the power of personal density control, going from completely intangible to super-dense with enhanced strength and invulnerability.
  • Charlie Dimes: an alcoholic and crazy bum on the streets of Gotham; human with no known metahuman abilities.
  • Goldie Johnson: female freelance reporter for The Daily Bugle in New York, specializes in weird ‘tabloid’ stories; human with no known metahuman abilities.
  • Marco Xavier: A competent, low-level flunky in the Friends of Humanity organization, used to gain inside information on the human supremacist organization.

Flaws[edit | edit source]

Cookie Addiction[edit | edit source]

J'onn is extremely fond of Choco (and Oreo) cookies, to the point of addiction. It is unknown if this is a physical or psychological addiction, but J'onn sometimes experiences withdrawal symptoms such as shortness of temper or mental regression. Or he may just be messing with people's heads. Nonetheless, he almost always has a bag or two on hand.

Outsider[edit | edit source]

J'onn is a perpetual outsider, the last survivor of Mars and powerful beyond belief compared to a normal human. As such, he sometimes has trouble relating to the normal people that make up the vast bulk of the population of his adopted homeworld. In addition, his inhuman form (itself a compromise between a human shape and his more inhuman native form) can sometimes instill fear in people despite his attempts to remain comforting.

Fire[edit | edit source]

As a Green Martian, J'onn suffers from an intense pyrophobia. Although he has been on earth long enough to control this racially instinctive fear around small or controlled fires, he still becomes extremely distressed and panicked while in the presence of large, uncontrolled, or hostile blazes. In addition to the mental mesmerism and pyrophobia inspired by open flame, he suffers a heightened physiological reaction to fire. His nigh-invulnerable form is easily burned by fire (not mere heat, but actual flame), and his other abilities become extremely hard to use. In extreme cases, such as being bathed in continuous, high-intensity blaze, the Martian Manhunter has been known to lose cohesion over his form entirely and melt in a sentient, terrified puddle. This is tied directly to a Martian’s telepathic abilities, and he loses this weakness if he loses or is shut off from his telepathic abilities, then he also loses the weakness to fire. J’onn has been known, on occasion, to shut down his own telepathic abilities to lessen his vulnerability to fire, and he has been on Earth long enough to attain enough control that he can handle the presence of small, controlled fires with little issue.

Enemies[edit | edit source]



'Enemies: J’onn has fewer living enemies than other superheroes, and is almost entirely without a personal rogue’s gallery. Most of his enemies are actually the League’s enemies, but he does have a few very specific grudges.

Darkseid[edit | edit source]

J’onn’s grudge against the ruler of Apokolips goes back a very long way, to the height of Martian civilization and J’onn’s career as a Manhunter. Both parties have a long-standing hatred of the other.

Kanto[edit | edit source]

Another New God in Darkseid’s employ as an assassin, this traitorous cur was once J’onn’s friend, until the betrayal of the Martians. J’onn knows he is a treacherous and untrustworthy villain, which makes him fairly reliable as an unwitting ally when J’onn turns the tables on him.

Human Flame[edit | edit source]

A joke among the supervillain community, the Human Flame is basically a guy in a flamethrower suit. However, he was humiliated and caught by the Martian Manhunter early in his career and has sworn revenge.

Doctor Trap[edit | edit source]

An old foe of the Justice Experience, a minor super-team precursor to the Justice League; has cybernetic jaws and an extraordinary intellect and strong mind, greatest desire is to kill J’onn and Agent Chase of the DEO, wiping out all members and relatives of the Justice Experience.
