J'onn J'onzz (Earth-7642)

**J'onn J'onzz** is the **Martian Manhunter**, a law enforcement officer from Mars who became a police detective and superhero after becoming marooned on Earth. He is a founding member of the Justice League of Avengers.

## History

### Origin

In 1955, J'onn J'onzz was transported from Mars to Earth due to a Zeta-Beam accident that took place during an experiment conducted by Dr. Erdel. Stranded on Earth for decades, J'onn became the hero Martian Manhunter.

### John Jones, Police Detective

J'onn was able to use his powers to fit into human society. He adopted a human appearance and called himself "John Jones." He became a police detective in the city of Middleton. For a long time, he worked as a policeman while secretly using his alien powers to solve cases and help people.

## Powers and Abilities

### Powers

* **Martian Physiology**: Martian Manhunter has been described as "the Swiss Army knife of superheroes." He possesses many of the powers of Superman. *Note: Many, if not all of the Martian Manhunter's powers and abilities are common to members of his race, even if demonstration of such abilities has not been explicitly shown in a canonical resource.*His powers come from his alien physiology. Born on Mars over a millennium ago, from a super advanced civilization, boasting advanced technology and genetic modifications over its people, the Martian Manhunter would appear to be a genetically modified being with incredible powers stemming from the changes made in his body.[*citation needed*] Whether this is their natural state or an advanced state given to only a few individuals is unknown. The Martian's physiology would seem to be composed of a complex molecular chain that resembles polymer bonds but with the ability to be altered at will. The Martian Manhunter can change his mass, color, relative shape, imitating even clothing if desired. The biopolymer is extremely flexible, durable, incredibly strong for a biological material and apparently self-sustaining.[27] It is unknown if the Martian Manhunter actually needs to eat or not but he has been seen consuming food, particularly "Chocos," a brand of cookies.
	+ **Shape-Shifting**, **Malleability**, **Plasticity**, **Elongation**: Arguably one of the most incredible powers possessed by the Manhunter is the ability to shape-shift. He is able to literally control the molecular structure of his body's biopolymers and manipulate them into any construct he desires, in addition to and including his own body. He can form clothing and weapons with non-moving or non-functioning parts. There does not seem to be any limit to the number of people the Manhunter can imitate and has stood in as a double for many famous people. His ability to imitate people and their mannerisms has stood him in good stead for his disguises. He has recently been seen to shape-shift into the size and shape of a common house fly and to enormous sizes comparable to skyscrapers.
	+ **Invisibility**: The Manhunter can cause the biopolymers in his body to lose their ability to reflect light, rendering the Manhunter invisible to normal light and human sight. With more increased concentration, he can render himself completely invisible along the electromagnetic spectrum, including the infrared and the ultraviolet ranges of the spectrum. This invisibility does not affect every other sense and he could still be detected by touch.
	+ **Phasing**: The Manhunter can phase through solid matter. No explanation of this power has been given, but it might possibly be an aspect of his psionic powers, perhaps shifting his mass into another dimension or out of vibrational phase with other objects in this dimension. Since it is known that he can alter the density of his biopolymers, it may be that he can simply become less substantial than solid matter, thereby decreasing the molecular density of his body by loosening the bonds within the biopolymers, due to - and further demonstrating - the absolute control he has over them.
	+ **Superhuman Durability**: The biomorphic structure of the Manhunter's body allows him to absorb almost all kinetic energies such as high caliber bullets, shrapnel, or flying debris easily. He can harden his biopolymers by rebinding them and increase his durability to the point where he is nearly on par with Superman. Along with his nigh-invulnerability, his shape shifting makes him even more difficult to harm. Hazardous environments practically do not affect the Martian Manhunter.
		- **Toxic Immunity**: In addition, Martian Manhunter's immune system protects him from all toxins and diseases (meaning he is unable to succumb to any earthly poison, disease or infection).
	+ **Superhuman Strength**: The Martian Manhunter is one of the strongest beings on the planet. The Martian's superhuman strength comes from his Biomorphic structure formed from immensely long and complex molecular chains,[*citation needed*] augmented with his psionic and telekinetic abilities allowing him to lift incredible weights without these weights crumbling under the stress. The Martian has been seen lifting tankers out of the ocean for vast distances, stalemating powerhouses like Superman, and he has even helped tow the moon and objects as large as the Earth itself together with Superman. J'onn's strength is great enough to the point that he has drawn blood from beings as durable as Kryptonians such as Supergirl by his punches alone. By modifying the density of these biopolymers, the Manhunter can make himself stronger by forcing them into tighter bundles. While at a resting state the limits of his strength are unknown, the Manhunter can lift 100 tons without much effort. He is nearly as strong as the likes of Superman when concentrating his biopolymers to their full capacity.
	+ **Superhuman Stamina**: J'onn's endurance is just as formidable as his strength and invulnerability. He can operate under extreme conditions for an indeterminate period of time without showing signs of fatigue. The exact range of this power is unknown.
	+ **Regeneration**: The Martian Manhunter has shown amazing regenerative capabilities. So great are they that he has been able to completely regenerate from nothing but his severed hand,[29] regenerate in moments from nothing more than a puddle of green liquid, and in another instance, survived beheading.
	+ **Flight**: The Martian Manhunter flies by manipulation of gravitons (a subatomic particle associated with the force of gravity), manipulation of magnetic fields and control of his absolute molecular movement (a telekinetic effect). These combine to give him the ability to fly great distances with little fatigue and at great speed. The Manhunter has also been seen flying in space with no difficulty, and in space he can fly at speeds that have allowed him to keep up with the likes of even Superman. J'onn can therefore fly at speeds exceeding the escape velocity of earth (7 miles per second) under his own power.
	+ **Superhuman Speed**: Either through flight or natural movement, the Martian Manhunter can maintain speed and demonstrates reflexes far in excess to that of most metahumans, and for far longer. Like the power of flight, this is accomplished by manipulating the magnetic fields of energy surrounding his body, as well as ambient gravitational particles. Traditionally, J'onn only uses his superhuman speed while flying. He has admitted that he is not as fast as Superman but this can be argued as he has shown speed feats that are nearly at Superman's level, such as the speed necessary to fly around the earth destroying multiple targets around the planet in seconds, while also managing to save Kyle Rayner in the end. He can process thoughts, move, and react at super speed as well. J'onn has also demonstrated that he is fast enough to comfortably catch bullets and other exceedingly fast projectiles.
	+ **Extrasensory Input**: J'onn possesses nine different senses. One of these senses could account for instances of the Manhunter's perceived precognitive abilities.
	+ **Longevity**
	+ **Super Hearing**
	+ **Super-Breath**: The inner valves and chambers inside the Martian Manhunter's air canals are very dense and greatly enhanced, allowing him to, much like Superman, create strong hurricane force winds just by exhaling pressurized air from his lungs in an incredibly strong burst.[*citation needed*]
	+ **Enhanced Senses**
		- **Martian Vision**: The actual nature of this power seems to vary depending on the reports. It has been seen to be a bolt of force, directed by the Manhunter's eyes causing considerable damage. It has also been seen to cause flammable objects to catch fire. It also grants J'onn the ability to see into other spectrums of light. J'onn can use his Martian vision to see people and objects that are invisible to others. For example, upon their first meeting, J'onn's power allowed him to see past Gypsy's metahuman camouflage ability; other effects are, at present, unknown.
			* **Electro-Magnetic Spectrum Vision**
			* **Telescopic Vision**
			* **Microscopic Vision**
			* **Heat Vision**
	+ **Telepathy**: The Martian Manhunter is the one of the most powerful telepaths on the planet, and is one of the strongest telepathic beings in the Universe. He is able to read the mind of any human with no difficulties, and the only minds that can cause him trouble are insane minds. He can even read the subconscious mind as well. He is able to read minds over great distances and has been known to scan the mind of every person on Earth within a matter of moments. This telepathy extends to distances as far away as the moon, since it is known that the Martian Manhunter can telepathically communicate with someone on Earth while on the moon. It is not known whether there is any limit to the number of people he can be attuned to or whether there are any special requirements to being attuned to him. In addition to reading minds, the Martian Manhunter has a multitude of other telepathic capabilities, one of which allows him to literally reprogram the mind of a subject into believing whatever he wants them to. He can use this ability to help subjects forget things that he does not want them to remember as well as set up post-hypnotic suggestions.
		- **Illusions**
		- **Possession**
		- **Astral Projection**
		- **Mind Control**: The Martian Manhunter can also control other beings mind's. Insane minds seem to be the only minds he has some trouble controlling.[*citation needed*]
		- **Telepathic Relay**: Otherwise known as a telepathic link. As a Class 3 telepath, the Manhunter is able to use his telepathic prowess as a relay station for a group of minds, who can then "speak" to each other through him. This relaying ability seems to be limited to the same range as the Manhunter's normal telepathic range.
		- **Telepathic Assault**: The Martian Manhunter can also use his telepathic abilities in an offensive manner. He has the ability to cause mental shutdown in a target using his psionic powers. The Manhunter does not use this power often due to the invasive nature and harshness of such a telepathic attack.
		- **Thought Sensing**: The Manhunter can use the mental signature of a being to track it, and can detect life forms by their empathic as well as telepathic signatures. He can detect whether a being is intelligent or not, and can communicate with it empathically if it does not have a communication-driven frame of reference with which normal telepathy may function. He can also detect various states of mind from anywhere in the world.[*citation needed*]
		- **Mayavana (Formerly)**: One of the most prized abilities of the Martians is Mayavana. It is the ability to reach into another mind and create a mental reality as real as any normal reality. The strain of Mayavana is such that it can only be used once in a lifetime, and so is normally used on the one that a Martian loves the most. J'onn used it on the rampaging Despero so that he thought that he had destroyed the JLH (subsequently he reverted to an embryonic state) and therefore saved his friends.
	+ **Telekinesis**: J'onn possesses the ability to move objects with his mind, which he described as ""molecular hypnosis" and "Martian mind-over-matter".
	+ **Matter Absorption**: J'onn has the ability to absorb matter and add it to his own mass, he once used this ability to grow to the size of the gigantic Antares and in another occasion to enhance his regenerative abilities.

### Abilities

* **Genius Level Intellect**: The Martian Manhunter possesses highly advanced reasoning and logic capabilities, and uses them to great effect. Despero once claimed that Ted Kord's mind (IQ 192) was second only to that of J'onn J'onzz. The Martian Manhunter's particularly astute reasoning capabilities and long-term association with Earth's global population gives him an edge in dealing with humans of diverse governments, cultures and religions. As a result, in the northern hemisphere of Earth, the Manhunter is one of many costumed adventurers battling against entropy, yet in the southern hemisphere, he is more well-known than even Superman.
* **Weaponry**: Is skilled in the use of a trident.
* **Investigation**
* **Multilingualism**: The Martian Manhunter is able to speak several languages, those include: Martian, English, Portuguese, Japanese, Russian, Italian.
* **Meditation**: Martians enter a meditative state as a form of sleep.

### Weaknesses

* **Vulnerability to Fire**: The Martian Manhunter has a psychosomatic fear of fire. The Guardians of the Universe have built in a fear of fire when they first confronted the Burned (Martians). Exposure to fire, causes him to lose his powers, and in the case of extreme fire, to lose his control over his biomorphic form. The Manhunter is more vulnerable in this form and can take damage in this vulnerable state.
* **Chocoholism**: It has also been suggested that something within J'onn's physiology makes him addicted to the chemicals used in the Earth snack, Chocos. Withdrawal symptoms include violent bursts of rage and loss of intellect. However, these claims have never been accurately substantiated, and may even be false.
