Martian Manhunter

J'onn J'onzz, also known as the Martian Manhunter, is one of the major characters from the DC Comics.

Sole survivor of the Martian people, J'onn J'onzz was teleported to Earth decades ago by Dr. Saul Erdel. Since then, he has adopted Earth as his new home, playing many roles over his time with humanity: detective, secret agent, explorer, and even a pillar of the Justice League.

Personality
Like all Martians, J'onn has a somewhat cold and stoic demeanor. He has very restricted emotional expressions. J'onn typically acts as the voice of reason in the Justice League and is one of the wisest leaders within the hero community, along with Batman and Superman.

Despite his cold exterior, J'onn is one of the kindest and most noble heroes operating on earth. The Manhunter has demonstrated enormous willpower, as evidenced by his ability to retain his sanity after the death of his race. He has a subtle sense of humor and an affinity for the chocolate cookie sandwiches called Chocos. The Martian Manhunter is considered by many to be the heart and soul of the Justice League.

Abilities
Martian Manhunter possesses powers and abilities common to all Martians but has shown to be the most powerful of his race, largely due to be from his training as a Manhunter of Mars, and also his years as hero of Earth. J'onn was trained as a Manhunter on Mars, making a capable crime fighter and combatant. Since his arrival on earth, he has demonstrated a high degree of intelligence and great skill in detective work while working under the guise of Detective John Jones. Martian Manhunter has exceptionally high reasoning and logical skills, which added to his detective expertise, and also grants him highly competent diplomatic abilities. He has shown to be remarkably empathetic and understanding of human emotions and human nature. He has often given extremely wise advice to his fellows during times of crisis and in personal adversity. Despite his civil understanding, J'onn is able to assess situations and recognize which circumstances require intellectual solutions and which merit combat. When he has decided to use force, he has never been hesitant to fight against his opponents ruthlessly.
 * Super Strength - Martian Manhunter is one of the strongest heroes on Earth, with strength comparable to Superman. J'onn along with Superman was able to move one of Brainiac's ships away from Earth; the ship in question dwarfed the planet with its size and was hurtling towards the Earth at 36,000 miles/hour. J'onn has also shattered Earth's moon with his strength.
 * Invulnerability - J'onn's durability has allowed him to withstand the destruction of Earth's moon without so much as a scratch, as well as taking hits from characters like Superman and Wonder Woman. He has in the past displayed the ability to make his body more dense in order to boost his durability, or his resistance to gaseous or chemical agents.
 * Flight - Martian Manhunter has been seen flying at Mach 10 in Earth's atmosphere. He has maneuverability and flight speed comparable to Superman.
 * Super Speed - J'onn and other Martians have speed that allows him to keep up with the Flash. His speed grants him accelerated reaction times as well. He is able to process thoughts and carry out actions with incredible speed as well. He can even utilize his telepathy at super speed, able to create a telepathic conference room for the Justice League to discuss matters in the privacy of J'onn's mind in just an instant.
 * Stamina - The Martian Manhunter has nigh inexhaustible endurance and resilience. He can last for extensive periods of time without food, rest, or air. J'onn has been able to travel great distances in space and fight long battles without tiring.
 * Regeneration - J'onn can quickly recover from almost any injury. He is able to reconstitute his body even when severed into several pieces. His regenerative abilities have allowed him to reconstitute his body from even an extremely small mass in only a matter of seconds, and he has even grown a new body from a severed arm.
 * Shape-Shifting - The Martian Manhunter 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. It has been revealed in the older comics, that he takes the powers and weaknesses of whoever he turns into. 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 during his fight with Ultraman. He has elongated parts of himself into bladed weapons during combat. 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. 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.
 * Intangibility - By greatly lowering the density of his own mass, Marian Manhunter 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. Another use of this power is phasing opponents into solid objects, as J'onn as Fernus was able to do to Superman.
 * Invisibility - J'onn is able to control his visibility and render himself invisible to beings that can even view the entire electromagnetic spectrum. He can even appear invisible to Superman.
 * Telepathy - Martian Manhunter is one of the most powerful telepaths in the DC universe. Through sheer mental strength, he was able to resist Brainiac's telepathic control of the entire world. His offensive psionic abilities are at least planetary in scale, and he has demonstrated great finesse with his powers - achieving everything from planting subtle subliminal messages in Superman's head, casting an illusion over the entire Justice League, and forcibly invading and shutting down the minds of powerful telepaths like Despero and Doctor Psycho.
 * Psionic Blast - J'onn is able to project painful and destructive blasts of psionic energy from his eyes and his hands
 * Psionic Shield - J'onn is able to project a telekinetic shield of distinct size and force for their protection and that of others.
 * Martian Vision - Martian Manhunter can project powerful blasts of energy from his eyes. The power of these blasts are comparable to Superman's heat vision and have been shown to be able to harm the likes of Superman and Black Adam. He is able to create powerful enough blast to sever his own arm. He is also able to project telekinetic blasts of force.
 * Telekinesis - Presumably a side effect of his Martian vision is telekinesis. He seems to keep this ability in reserve, as he does some of his other powers. J'onn is capable of controlling / manipulating; move; push; cut out; attrack; and levitate objects even at the subatomic level. J'onn can manipulate atoms, subatomic particles, and cells perfectly. J'onn can fire extremely powerful Telekinetic Blasts, causing others to telekinetically explode and create a telekinetic shield. J'onn has only demonstrated this power a select few times.
 * Martian Breath - The Martian Manhunter has also demonstrated an increased lung capacity, allowing him to blow powerful wind bursts and freeze opponents with his breath, similar to Superman. J'onn has also demonstrated the ability to fly through space for extended periods of time.
 * Sonic Scream - J'onn has on occasion demonstrated the capability to emit a devastating sonic scream.
 * X-ray Vision - J'onn J'onzz described this ability colloquially as ionized particulate matter mapped to a variable density wavepacket. It allows him to see through objects.
 * Extrasensory Input - Martians have nine senses as opposed to a human's five senses, which grants the Martian more numerable and clearer perceptions.
 * Longevity - Martians possess naturally longer lifespans than human beings. J'onn has lived for at least one hundred years and is still not at old age. Based on the "One Million" story-line, we can also presume that J'onn has the capacity to live and operate at peak functionality for thousands of years to come.
 * Mayavanna (Formerly) - This is a Martian ability that gives the receiver a gift of a reality even more powerful than our own. It grants them what they want most in the world and is reserved for those held most dear to the Martian giving it. It is a gift that can only be given once in a lifetime. J'onn had to use his on Despero in order to stop him from murdering the League.

Trivia

 * Although this character was originally introduced during DC's Earth-One era of publication, their existence following the events of the 1985–86 limited series Crisis on Infinite Earths remains intact. However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earthcontinuity, and should be considered apocryphal.
 * Although obviously alien in appearance, the form that most Earthlings associated with the Martian Manhunter is not actually his true form. In his natural state of being, J'onn has a slender body, with sharp, angular features and a tapered cranium. The more muscular "beetle-brow" appearance was inspired by Saul Erdel, who convinced J'onn to assume a form derived from the literary works of science fiction authors such as Edgar Rice Burroughs and Ray Bradbury.[41]
 * In Earth-One continuity, the Martian Manhunter quit his tenure with the Justice League of America in Justice League of America #71 and did not officially return to active status until the reformation of the League in Justice League of America Annual #2. However, Post-Crisis continuity has retroactively re-inserted J'onn as an active League member for the entire span of the first iteration of the JLA.
 * Batman left one Choco on his casket.
