- I'm Mars' sole survivor... there's a reason for that.
- — J'onn J'onzz src
J'onn J'onzz had never been a violent man, but found himself drawn into what came known as "The Martian Holocaust", a war between the Green Martians and the White Martians. The war resulted in the death of his wife and daughter, along with both Martian races being entirely wiped out. J'onn J'onzz seemed to be the sole survivor of Mars.
Some time later, J'onn encountered and befriended Jor-El. Through Jor-El, J'onn found purpose again. Working for Jor-El, J'onn brought criminals (both Kryptonian and criminals from other worlds) to justice, who were then banished to the Phantom Zone. When Krypton was facing destruction, Jor-El asked J'onn to watch over his son, whom he planned to send to Earth. However, Jor-El had arranged for the boy to be put before tests. Tests that Jor-El wanted him to pass on his own. So, J'onn was forbidden to interfere, unless it proved absolutely necessary. Because of this, J'onn kept an eye on Clark from a distance, rather than interacting with him directly.
After Clark accidentally released several prisoners from the Phantom Zone, J'onn quickly found that he had no choice and had to interfere. The first time occured in Seattle, when Clark attempted to bring down Aldar, only to be nearly be killed by him. Just before Aldar was going to kill Clark, J'onn rushed in and killed Aldar. Before Clark could ask him any questions, J'onn flew away. The second time, that J'onn had to step in, was when another escapee from the Phantom Zone infected Clark's mind and trapped him in a nightmarish reality, in an attempt to get control of Clark's body. J'onn entered Clark's mind and was able to convince him of the truth. When the phantom was expelled from Clark's body, J'onn used a crystal to return it to the Phantom Zone.
A few months later, J'onn tracked down the last escapee from the Phantom Zone in Canada but was critically wounded in the confrontation and was forced to flee. Due to his injured state, J'onn had no choice but to leave the last phantom to Clark, while he himself left Earth's atmosphere to heal. Upon his return, J'onn discovered that Clark had not only failed in stopping the phantom, but that it had cloned him. Despite this, J'onn stood by Clark and took care of the phantom, after Clark had defeated him in battle.
A few weeks later, J'onn returned to the Kent Farm, as he was concerned about the recent appearance of Kara Zor-El, as her father had tried to kill Jor-El. However, when he confronted Kara with the truth about her father, it prompted her to run off. Once more J'onn helped Clark take care of a problem, when he took Curtis Knox to Mars.
After Clark was mortally wounded, while in a powerless state, J'onn decided that he couldn't stand by and let Clark die. He took Clark's dying body and flew into the sun, which healed Clark and returned his abilities. However, while this incident had restored Clark's powers, it had robbed J'onn of his. Leaving him powerless and in his human guise. This situation led him to create a human identity for himself, John Jones, and became a homicide detective with the Metropolis Police Department. While he occasionally continued to help Clark, his time as a detective allowed him to see that there were others in the world, who needed his help more than Clark did. He also joined Green Arrow's team.
Right before his death, Dr. Fate restored the powers of J'onn. Despite this, J'onn kept his identity as detective John Jones and began investigating the government agency known as Checkmate, which was out to get superheroes like the Blur (Clark) and Green Arrow. An operation that forced him to become allies with the mysterious Red Queen. To protect the others, he wiped Amanda Waller's mind of any knowledge about the identities of the heroes involved in the Watchtower Network.
While attending the funeral of Carter Hall, J'onn and the other Watchtower members were captured by the Department of Domestic Security and trapped inside a virtual world but were later saved by Chloe Sullivan and the Suicide Squad.
Six months after the event known as "Contact", J'onn began suffering from flashbacks to the death of the Martian race. Which alerted him to the presence of another Martian. Specifically, a White Martian. With the aid of Bruce Wayne, J'onn was able to track down the White Martian in question. However, he soon discovered that the girl, M'gann, wasn't a threat and took her in, passing her off her his niece to his neighbors.
J'onn was among the heroes assembled to battle the Monitors in Metropolis. After the battle he joined six of the other heroes and became a founding member of the team known as the "Justice League".
Powers and Abilities
- Martian Physiology: The average Martian possesses the potential for the following power set:
- Shape-Shifting: Martians have psionic control of their physical for down to the molecular level. This allows them to a form of shape-shifting that allows them to mimic other forms, elongate aspects of their body, increase or decrease their physical size, and so on.
- Invisibility: Martians can cause the biopolymers in their bodies to lose their ability to reflect light, making the Martians invisible to normal light and human sight.
- Phasing: Martians can go through solid matter.
- Superhuman Strength: Martians possess vast levels of superhuman strength and are among the few races that are able to match Kryptonians in terms of raw strength. Martians can easily shatter reinforced concrete and steel, lift and carry houndreds of tons with ease and deliver incredible damage with their blows.
- Superhuman Stamina
- Superhuman Durability: Martians possess high levels of durability that make them nigh-invulnerable to all forms of damage. Martians can withstand high caliber bullets, powerful energy blast and kinetic impacts without suffering damage.
- Superhuman Speed: Martians can process thoughts, move, and react at incredible speed, being able to cover vast distances in little or no time, catch bullets in mid flight, run on water and create afterimages as they run.
- Regeneration: Martians have powerful regenerative powers that enable them to regenerate their entire body from a severed limb, they can furtherly enhance their regenerative powers by drawing mass from nearby sources.
- Extrasensory Input
- Super Hearing
- Heat Vision
- Martian Vision: Martian visual acuity greatly exceed human norms and allows for a wider range of information to be observed. This includes the following:
- Telepathy: Martians have the ability to read the minds of others and project their thoughts to varying degrees. They can also project their mental essences into a gestalt community known as the "Great Mind". Through this, the community can enhance the telepathic strength of other Martians. This power can also enable them to reverse the effects of amnesia or psychological brainwashing. 
- Astral Projection
- Mind Control: As an extension of this, Martians can also use the ability to alter a psychological profile of a target, enabling them to manipulate, and in some cases, outright control that individual. This practice is greatly discouraged however, and only rarely used. 
- Telepathic Relay
- Telepathic Assault
- Telekinesis: Martians have mind-over-matter abilities and can lift and move objects with their minds. They can also employ their telekinesis in offensive way by discharging telekinetic blasts capable of great concussive power.
- Vulnerability to Fire: Martians are much more vulnerable to fire than the average Earth human. At times this has been portrayed as physical, psychological, or a combination of the two. The effect of this is to strip any Martian of their powers as they involuntarily lose control of their body.
- Vulnerability to Earth's Atmosphere: The effects of Earth's atmosphere negates his ability to heal. For it to work, J'onn has to leave the atmosphere.
