Genetically Modified 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 of 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. 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 bio-polymer is extremely flexible, durable, incredibly strong for a biological material and apparently self-sustaining. 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: The most incredible of the powers of the Manhunter is the ability to shape-shift. He is able to literally control the molecular structure of his body's bio-polymer and make it resemble anything he wants. 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. He is also able to change colors.
Invisibility:: The Manhunter can cause the bio-polymers 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: No physical explanation of this power make sense except that it is an aspect of his psionic powers shifting his mass into another dimension or out of vibrational phase with other objects in this dimension.
Superhuman Durability: The bio-morphic 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 bio-polymers 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. He has proven to be immune to all known human diseases, but no experimentation has been done to see what more advanced viruses such as ebola or anthrax might have.
Superhuman Strength: The Martian Manhunter is one of the strongest beings on the planet. The Martian's superhuman strength comes from his plasmorphic structure formed from immensely long and complex molecular chains, 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 bio-polymers, the Manhunter can make himself stronger by forcing the polymers into tighter bundles. While at a rest state the limits of his strength are unknown, the Manhunter can lift 100 tons without much effort. He is nearly as powerful as the likes of Superman when concentrating his bio-polymers to their full capabilities.
Superhuman Endurance: J'onn's endurance is just as formidable as his strength or 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 abilities. His regenerative abilities are so great that he has been able to completely regenerate from nothing but his severed hand, regenerate in moments from nothing than a puddle of green liquid and other moments, having his head cut off, and he has shown total control over his molecular structure.
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. He has been seen to fly at Mach 10 speeds (7690 mph) in the Earth's atmosphere. Speeds faster than this cause great environmental damage and are avoided unless absolutely necessary. His bio-polymorphic skin and overall toughness make these speeds bearable and cause him no injury. The Manhunter has also been seen flying in space with no difficulty, and in space he can fly at speeds that has 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 reflexes far in excess to that of even most superhumans. 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 is nearly at Superman's level, such as the speed necessary to fly around the earth destroying multiple targets around the planet in seconds and managed to also save Kyle Rayner in the end. He can process thoughts, move, and react at super speed. J'on has also demonstarted that he is fast enough to comfortably catch bullets and other propelled projectiles.
Extrasensory Input: J'onn possesses nine different senses. One of these senses could account for instances of the Manhunter's perceived precognitive abilities (see Trivia).
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 sending pressured air out.
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, he has shown that he could easily cause damage greater than 1000 lbs of TNT. It has also been seen to cause flammable objects to catch fire. The range of this power is also unknown but has been seen to be effective at ranges of 1000 feet and more. He can increase the power of his Martian Vision to levels that would even injure the likes of Superman. It also grants J'onn the ability to see into other spectrums of light. J'onn can use his Martian vision to see the invisible. For example, upon their first meeting, J'onn's power allowed him to see pastGypsy's Metahuman camouflage ability; other effects unknown.
Electro-Magnetic Spectrum Vision
Telepathy: The Martian Manhunter is the most powerful telepath 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 their subconscious mind as well. He can scan the mind of every person on Earth within a matter of moments. He can read a mind over great distances. This telepathy extends to distances as far away as the moon, since it is known that the Martian Manhunter can communicate with Earth with his telepathy. 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.
Mental Shield: He can prevent other telepaths from reading his mind. He can expand this ability and shield other people from telepathy.
Download Information: Has demonstrated this by downloading information on how to fly a martian space ship into Batman's brain.
Mind Control: The Martian Manhunter can also control other beings minds. Insane minds seem to be the only minds he has some trouble controlling.
Thought Sensing: The Manhunter can use the mental signature of a being to track it and can detect lifeforms by their empathic as well as telepathic signatures. He can detect whether a being is intelligent and can communicate with it emphatically if it does not have a communication driven frame of reference for normal telepathy to function with. He can also detect various states of mind from anywhere in the world.
Telepathic Relay: Other wise 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 Manhunters 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 mental powers. The Manhunter does not use this power often due to the invasive nature and harshness of such a telepathic attack.
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 life time, 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.
Expert Mediator: The Martian Manhunter's sound reasoning capabilities and long term association Earth's global population, gives him an edge in dealing with humans of diverse governments, cultures and religions. In the northern hemisphere, the Martian Manhunter is one of many costumed adventurers battling against entropy. In the southern hemisphere of Earth, the Martian Manhunter is more well known than Superman. Considered the scourge of the underworld because of his dedication to truth and improving the lot of humanity everywhere, he is feared by underworld criminals worldwide. His noted skills include:
Master Detective: Highly developed detective skills.
Logical Mind: Advanced reasoning and logic capabilities. Despero once claimed that Ted Kord's mind (IQ 192) was second only to that of J'onn J'onzz.
Personable Attitude: Excellent human relations skills.
Multi-lingual: Fluent in all Earth languages.
Emotional Attunement: Highly developed empathic abilities.
Class 100+; J'onn can lift well over 100 tons . On Earth, the Martian Manhunter is physically one of the mightiest heroes possessing vast levels of superhuman strength, strong enough to lift tremendous weights even at a rest state, however on Mars J'onn possesses the strength level of an average adult male Martian in peak physical condition. He has shown that his strength is on par to the likes of Superman and Wonder Woman and he has shown that his is so strong he is capable of helping move objects as large as the planet earth.
Psychic Pyrophobia: The Martian Manhunter has a psychosomatic fear of fire. It is unknown what the source of this fear is, whether it is a personal fear or a cultural fear, but whichever it is, it is a paralytic fear with the Manhunter. 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.
He is now invulnerable to flames unless they are "flames of passion" or of some other "psychic significance".
Choco Addiction: 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..
