John Jones is a super-powered alien from the planet Mars, and is the planet's sole survior. He currently works in Metropolis as a Lieutenant Homicide Detective for the Metropolis Police Department and is a part-time member of Clark Kent's team of heroes. Before John came to Earth, he once worked as an intergalactic bounty hunter known as the Martian Manhunter in which he helped Jor-El trap and imprison criminals from the 28 known galaxies. (Labyrinth)
John promised to watch over Jor-El's son Kal-El in order to make sure that he fulfilled his destiny; apparently, he has been watching Clark from a distance since Jonathan and Martha found him. (Phantom)
John has saved Clark on many occasions since making his presence known to him in late 2006 and is there to give him advice and guidance in Jor-El's absence. Since then, he shows up to help Clark whenever a situation gets too much for him to handle. He made the ultimate sacrifice in the fall of 2008 saving Clark's life again by flying him into the sun and giving up his own powers to restore Clark's.
He got a job as a homicide detective for the Metropolis Police Department due to his powers being taken away by the sun. John's powers were recently returned to him by Doctor Fate who transported him to Mars, sacrificing his own life in the process and allowing himself to be killed by the villainous Icicle. (Absolute Justice, Part 2)
John has continued his police work even after his powers were restored. (Checkmate)
John, while in his true martian form, appears as a humanoid-like creature that has dark green skin, and has red eyes. According to a document written by Sylvester Pemberton, John is 6'7 and weighs 256 pounds.
He usually doesn't use his true form to interact, but instead, appears as an African American male (somewhere in his forties), and in this form, is often seen wearing a white dress shirt underneath a long leather jacket as well as trousers. He is usually wearing either a black or blue leather jacket, yellow or red shirt and dark trousers and recently wore a green shirt with a red X on his chest made from the double shoulder holstered guns under the jacket, a brown belt, black trousers and black shoes.
It is known that John has many inhuman organs and organic matter inside him because he is an extraterrestrial. (Bulletproof) When John saves Clark from Aldar, he leaves an inhuman hand-print on the Zoner's back. (Static) When Dr. Emil Hamilton conducts a diagnosis and later a procedure he finds out that John has alien organs. (Bulletproof)
John has been seen in his martian form in animated on-screen comic book Justice & Doom and Absolute Justice, Part 2 when Doctor Fate teleports him to Mars, which restores his powers and again while fighting Icicle.
- "Even when I had the power to leave Earth, I chose not to. For one reason - Hope. Hope for the future. Humanity's capacity for violence is great, but their capacity for hope is greater than any other I've ever encountered." - John Jones, Absolute Justice
John is indirectly portrayed as being exceptionally strong-willed, as he was able to watch Clark go through many unpleasant circumstances, and didn't intervene unless it was absolutely needed.[Citation needed] He is a vegetarian and has grown particularly fond of cookies, especially Oreoes. When he lost his powers after he saved Clark by flying him into the the yellow sun's heart, he became a homicide detective, which made him appreciate the immense power he once wielded, and pride later began to develop inside him, which made him reluctant to ask for help.
He strongly believes in destiny and is determined to help others fulfill their callings that he sees as worthy. He went as far as risking his own super powers to preserve Clark Kent's destiny. As one of Jor-El's oldest and closest friends, he admires the House of El, holding a special place for its members in his heart, with which he later demonstrates with Clark.
But Kara states that he forced her and Zor-El from their beds. (Cure) Before Krypton fully perished, he told Jor-El that he would only be a "watchful guardian", by monitoring his son Kal-El from afar till he was ready to complete his calling.
He is also very wise and often gives Clark advice on certain matters. He also seems to be close with Chloe and Oliver.
He believes that humans, while having a great potential for violence and betrayal, have a greater potential for good and promise. He uses this belief to convince Hawkman that giving up on humanity is not the answer. (Absolute Justice, Part 2)
Powers and Abilities
- See Also: Martian
As a martian, he doesn't seem to require an external power source but Mars' inner atmosphere can restore his abilities in the event of him losing them. So far, he has shown to posses most of the native Martian abilities. He may possess all abilities, but hasn't displayed them all yet.
- Super strength: John, as a martian, is incredibly strong, he can hurt other aliens, and easily overpower and kill humans as well as metahumans, and can lift extremely heavy objects. (Phantom, Bizarro, Absolute Justice, Part 2)
- Super speed: John can move and maneuver or react at hyper-sonic speeds. While running and or flying, John generally leaves behind a stream of red light. John is often quite discreet when he uses this ability, often appearing out of thin air. He first demonstrated this ability when he ran past the zoner Aldar without being noticed, except by Clark Kent, who noticed his movement. (Static) John, after extracting phantom Hudson from Clark's mind, dashes away rather quickly and shoots into the sky when he senses Chloe's presence. (Labyrinth) John, off-screen, is outside the Earth's atmosphere, when he senses that Clark is about to kill Lionel, he almost instantly appears and stops him. (Phantom) John runs to the Kents' house to speak with Clark, and gets in a heated conversation with Kara. (Cure) After Clark dies, John appears at his side and picks him up, and flies him into the sun's heart instantly. (Odyssey) When he regains his abilities with the help of Doctor Fate, John runs to Watchtower, and Chloe at first, thought that he was Clark. (Absolute Justice, Part 2) Although he didn't appear in the episode, when Lois said that she finished working on their apartment, Clark referenced the speed of John Jones and Bart Allen, questioning whether she had help unpacking by them using their super speed. (Dominion)
- Invulnerability: John possesses a very high durability threshold, and as such, he is highly resistant, and can withstand bullets (Checkmate) but high-tier aliens like Kryptonians can hurt him tremendously. (Phantom)
- Flight: John can easily defy the laws of gravity, allowing him to hover, levitate, or even maneuver, in the air at will, apparently through some type of telekinetic field. Because he rarely super speeds, he is more often seen traveling using this ability. (Static, Labyrinth, Phantom, Bizarro, Odyssey, Checkmate).
- Shapeshifting: John can alter his mass, density, and shape into virtually anything. His alien form is seen when Doctor Fate restores his powers and abilities. (Absolute Justice, Part 2) John morphed into Amanda Waller and tricked a grunt agent into releasing him. (Checkmate) John uses this ability to maintain his human form known as John Jones.
- Heat blast: John can emanate heat through his palms, causing the to burn hot. He used this ability on zoner Aldar to save Clark. After, and seemed to have used it on Icicle in the final battle at Watchtower. (Static, Absolute Justice, Part 2)
- Healing factor: John is very resistant, though he is far from being indestructible, and as such, he can heal from virtually any wound by leaving Earth's atmosphere, otherwise it won't work. (Phantom, Bizarro)
- Telepathy: John is inherently telepathic, and he can enter a being's mind mentally and can communicate them. Seeing no alternative, John enters Clark's mind to try to warn him that Hudson is trying to claim his body so he can activate and use his abilities. (Labyrinth) John, upon saving Clark and restoring his powers through the sun, senses that Clark wants to mature and to make a change without holding back. (Odyssey) He later senses that Clark used his X-ray vision ability on him. (Checkmate)
- Memory manipulation: Allowed John to wipe Amanda Waller's mind of the memory of Clark, Oliver and Chloe's faces. (Checkmate)
- Super stamina: John has an elevated stamina because he's an alien, and as such, can maintain constant movement for long periods of time. He was in space, and was able to fly to LuthorCorp Plaza to stop Clark from killing Lionel, and didn't seem tired at all. (Phantom) He later flew Bizarro on to Mars and returned unphased. (Bizarro). He proved this again when he flew Clark into the sun from the Earth without getting tired. (Odyssey)
- Invisibility: John was able to become temporarily invisible during the fight against Icicle. (Absolute Justice, Part 2)
- Intangibility: John has the ability to phase his body through any object or allow any object to pass through his body. This ability is linked to his willpower (Absolute Justice, Part 2, Checkmate).
- Martian vision: John can shoot threads of fire from his eyes. John used this to destroy the Kandorian blood sample. (Checkmate)
- Omni-lingualist — John proved to be fluent in many different languages. (Phantom)
- Skilled hand-to-hand combatant — As a detective, John has proved to be highly skilled when it comes to fighting an opponent in hand-to-hand combat. (Bulletproof)
For a period, John was depowered, having been stripped of his powers by Earth's yellow sun. (Odyssey) While he was depowered, J'onn J'onzz under his disguise as Detective John Jones proved to be a capable hand-to-hand combatant as he took down a criminal with relatively ease and apprehended him before being shot.
John is extremely vulnerable to fire of any kind, and prolonged exposure to it can, as shown when he flies Clark into the sun, remove his powers and abilities permanently unless he contacts Mars' inner atmosphere somehow, as shown when his abilities are restored when Dr. Fate teleports him to Mars. Additionally, John is afraid of fire. In Clark's hallucination, "John" was frightened by the flame of a lighter. Later, Amanda Waller was able to neutralize him by placing him within a "fire cage" with the bars made out of fire. Despite the close proximity of fire, he was somehow able to shapeshift and appear as Agent Waller, proving him capable of using his abilities in the presence of fire. John's healing factor is also inhibited while under Earth's atmosphere, possibly because of the high quantities of oxygen in the air. John is vulnerable to some physical attacks, proving that Martian damage resistance to be lower than a Kryptonian's. When Bizarro possessed a human, he was able to rip a hole in John's abdomen.
Close contact with the yellow sun seems to strip Martian Manhunter of all his powers. When he had to fly Clark into the sun to restore his powers, Martian Manhunter lost his powers, most likely due to his weakness of fire; but John decided Clark's destiny was greater than his own. His powers were later restored by Doctor Fate, by sending him temporarily to Mars.
John was born on Mars. Later, as an adult, he met a Martian female , married her, and together had a daughter. John would often leave his planet Mars and go to the planet Krypton to converse with the House of El dynasty , and would aid scientist Jor-El in capturing and imprisoning rogue aliens, casting them into the dimension wormhole called the Phantom Zone which was designed and built by Jor-El, creating his reputation as an extraterrestrial intergalactic bounty hunter.
After a group  of Kryptonian scientists conducted an experiment, resulting in the creation of an ill lab creation called Bizarro, and it was abused, resulting in its cold nature, which forced John help Jor-El trap him in the Phantom Zone, seeing the potential danger his presence would cause. John also made trips to Kandor and according to Kara Kent, he cast Zor-El and her from their home, forming a wedge between them. Before krypton was fully destroyed, Jor-El asked John to watch over his son Kal-El, and requested that he be a "watchful guardian" - John obliged.
Sometime later, due to unknown catastrophic circumstances, the entire Martian race was destroyed, leaving him the sole survivor of Mars. John, remembering his vow, stayed in space and watched over Clark as soon after he was found and adopted by Jonathan and Martha Kent.
- "Welcome home, Kal-El." – Martian Manhunter, to Clark Kent, Labyrinth
After watching Clark from a distance for the past several years, Martian Manhunter finally made his presence known when he saved Clark from the Zoner Aldar and made a quick escape, leaving behind an Oreo cookie at the scene and later at Clark's loft, indicating that he knew where Clark lived. He later explained that he wasn't to interfere with Clark's tests given to him by Jor-El unless it was absolutely necessary.
When Clark was attacked by Dr. Hudson, a Zoner who caused him to hallucinate that he was a patient in a mental asylum, Martian Manhunter telepathically entered Clark's mind to help him fight back against the phantom slowly taking over his body. There, in Clark's dream world, he was a fellow patient known as "John". John informed Clark that he was like him, but that he was from Mars. He later told a downtrodden Clark that Dr. Hudson was really a phantom and not to give into Dr. Hudson's claim that his powers were his imagination; he then told Clark that the only way to return to reality was to kill Dr. Hudson. When Clark attacked Dr. Hudson and broke free from his control, Martian Manhunter, back in reality, used a device (similar to the Crystal of El) to remove the phantom and return it to the Phantom Zone. Shortly afterward, he departed.
Sometime later, Martian Manhunter arrived in Quebec with the intention of trapping the Zoner later known as Bizarro, who was inhabiting the body of an old man. He prepared to do battle with him, but Bizarro punched a hole through his gut and ripped out some internal organs, severely wounding him. After he attempted to punch the Phantom and dealt almost no damage, Martian Manhunter was backhanded through the roof of the house and into the sky. Badly injured and weakened, he was forced to retreat. Martian Manhunter flew off to LuthorCorp to meet Lionel Luthor, Jor-El's emissary, to brief him of the failure. When he arrived, Martian Manhunter stopped Clark from killing Lionel and explained everything, including the significance of defeating Bizarro. He then departed in order to heal from the injuries inflicted upon him by Bizarro.
Justice & Doom
- "There are few that now know there is justice; that there can be no doom." - Martian Manhunter, Smallville Legends: Justice & Doom
The multimedia Smallville parallel story Justice & Doom he is shown helping the Justice League. It also suggests that Dr. Virgil Swann may have also communicated with Martian Manhunter, as the Manhunter used a large orbital Swann Communications satellite as a base.
He was also seen wearing a costume similar to the one he currently wears in the comics as well as turn into his Martian form at the end of the web story arc.
- "While humanity is your greatest strength, it is also your greatest vulnerability." – Martian Manhunter, to Clark, Bizarro
The Martian Manhunter managed to heal himself while in space, and spoke to Clark about Bizarro. He told Clark that he could beat his doppelganger by harnessing the energy of the yellow sun. At the end of the battle, Clark uppercut Bizarro towards the sun, where the Martian Manhunter caught him and flew Bizarro to the sunny side of Mars and imprisoned him there. After Bizarro's defeat, the Martian Manhunter came to congratulate Clark and told him that he is every bit as human as he could be on Earth.
The Martian Manhunter came back a while later to the Kent Farm, this time instantly grabbing Kara by the neck and warning her to stay away from Kal-El. They struggled until Clark stepped between them, and he told Clark that Kara couldn't be trusted, because her father Zor-El tried to kill Jor-El and was a traitor. The Martian Manhunter was told to deal with Dr. Curtis Knox by Clark and put him in a unknown location, telling him that there was a "don't ask and don't tell" partnership with Jor-El regarding the disposition of prisoners.
- "I promised Jor-El that I would only be a watchful guardian, but I could not stand by and let you die." – Martian Manhunter, to Clark Kent, Odyssey
The Martian Manhunter returned to save Clark's life after he was shot in the heart by the Green Arrow (who was temporarily under the influence of a mind-control serum developed by LuthorCorp). He took Clark and flew into the Earth's yellow sun where Clark was healed and his powers were restored. When Clark woke up in his barn, the Martian Manhunter told him that even though the sun heals Clark, it has the opposite effect on him, taking away his own powers. He tells Clark that he could no longer help him on his odyssey along with Jor-El. However, when Clark later spoke with the Justice League and Dinah Lance asked what had happened to the Martian Manhunter, Clark said that he was sure they'd see him again some day, suggesting that his powers may return at some point.
Later on, the Martian Manhunter returned, now a Metropolis homicide detective with the alias of "John Jones". He tried to help Clark solve the brutal killings that were going on and were connected to Davis Bloome somehow. Clark gave John a list of meteor infected people who could have something to do with the killings, which he had memorized from the signin sheet at Chloe's group therapy sessions at the Isis Foundation. John investigated the list, talking to each of the group members. He then later came to see Clark and told him that he can't save everyone and that if he is to carry on saving people in Metropolis, he should be more careful as there are millions of people in Metropolis and that he isn't in Smallville anymore.
After Kara Kent managed to escape the Phantom Zone, she sought out the Martian Manhunter to get his Martian crystal in order to capture the escapee, Faora who was fighting Clark and inhabited Lois Lane and was using her as a vessel.Oliver Queen and Chloe Sullivan. Oliver got Emil Hamilton because Ollie considered him a Justice League member since he protected Ollie from the police. In a few days, he later recovered, enough to have Clark cleared of charges for impersonating an officer. He admitted that the reason why he had to do things alone on his terms was feeling a bit of pride, which was hard to get past after becoming normal.
- "I hope it's not too late to say we come in peace." - Martian Manhunter, Absolute Justice, Part 2
Sylvester Pemberton had a page on John in the book about the Justice League. John was contacted by the Justice League when they were investigating a group who knew all of their identities and had once been heroes themselves, the Justice Society of America. John arrived at the League's request, joining them in defending their reasons for fighting crime nowadays and trying to convince the Society that the Earth was still filled with incredible amounts of hope.
The Society members had been being murdered by a young man known as Icicle, who needed to recharge his powers with liquid nitrogen. John went with Kent Nelson aka Doctor Fate, a sorcerer member of the Justice Society who could see people's fates to the nearest nitrogen storing facility in search of Icicle. While investigating Fate and John shared the mutual pain of losing their wives and family due to their responsibilities and heroes.
Fate realized that John's fate was greater than his own and seemingly attacked him, hitting him with a blast of magic that briefly teleported him to Mars and back, revealing John's true green Martian form which restored his powers. John was knocked unconscious by this just as Icicle arrived, impaling Fate through the chest. Fate was killed but his last act would not go without results. John was brought to the hospital where he was going through a metamorphosis.
The League and the Society fought Icicle in the Watchtower and when he was about to murder Courtney Whitmore, John arrived, his powers restored. He phased through an attack from the villain and helped his comrades defeat the villain for good. Later, John explained to Chloe that despite the fact that he was the last Martian, he was not alone and that the League was his family. Oliver arrived, inviting them to eat with him and John happily went, explaining that he'd grown accustomed to Earth food, especially cookies. When Clark left for vacation with Lois, he asked John to fill in for him as the Blur.Soon after, John secretly tried to investigate the agency known as Checkmate. Unfortunately his investigation pit him against Clark who found his motives suspicious. Unwilling to deal with Clark at the moment, John flew off. He then used his powers to read the mind of an agent of Checkmate to find the location of their headquarters in order to retrieve the stolen alien blood sample, Amanda Waller awaited for his arrival and sat up a trap that placed John in a cage made of fire. John used his shape-shifting ability to trick a guard by masquerading as Amanda Waller to release him from the fiery cage. John then proceeded to destroy the evidence of the blood sample with his Martian vision and before leaving wiped Waller's memory of her knowledge of the secret identities of members of the Justice League.
Later John met Clark at the Kent farm loft to discuss his current actions. It was revealed that John was working for the Red Queen to try to protect Clark from Checkmate and the White Queen (Amanda Waller) later it was revealed that the Red Queen was Martha Kent.
John was with the other Justice Heroes, that is with Black Canary, Cyborg, Hawkman, and Stargirl to discuss the battle against the Kandorians. He disagrees with Carter's idea to strike first and says they should stay with Clark's plan. When Clark announces his plan to leave with the Kandorians forever, John nods his head in agreement, and then signs out.
After Hawkman sacrificed his life to save Lois Lane from the villainous Slade Wilson, all Justice League members were required to attend a funeral service held in Carter's home country of Egypt, led by Stargirl. All members dressed in their trademark outfits with John walking behind the coffin. He was then left unconscious along with everybody else when a mysterious pyramid rose from the ground emitting a bright light.

In the Comics
Because of the relatively limited appearances of the Martian Manhunter on Smallville, little can be said about the show's interpretation of the character in comparison to the source material.
So far on the show, the Martian Manhunter has shown capabilities similar to most of his comic powers. His origin, however, has yet to be explored in detail. In the comics, the Martian Manhunter is the last surviving citizen of the planet Mars (which creates a special kinship with Superman) due to a war that broke out between two Martian races that laid waste to most of his world, killing the entire civilization. He also shares the obsession for black and white Choco Cookies (Due to copyright law, DC was unable to call it Oreo).
In the show, the Martian Manhunter has had contact with Jor-El prior to Krypton's destruction. While some DC stories established that the Martian civilization had communicated with Krypton, the Martian Manhunter had never actually met a Kryptonian before Superman in the source material.
In his debut story, the Martian Manhunter is accidentally teleported to Earth by scientist Dr. Saul Erdel, who immediately has a heart attack and dies, leaving the Martian stranded. He is able to use his powers to disguise his appearance, adopting the name of deceased Denver police detective John Jones. He joins the Middleton police force, secretly using his powers to help the inhabitants of Earth.
The Martian Manhunter's history is closely linked with that of the Justice League of America.
He is a founding member of the team, and served as a member during each of its various incarnations,with the exception of the League's most recent formation one year after the events of Infinite Crisis. Instead of joining the JLA this time, he was recruited by Batman to join the JLA splinter group: The Outsiders. Differences with Batman caused him to leave the group. He was last shown in Salvation Run, giving a status report to an unknown location regarding the villains trapped there. He has secretly taken the identity of Blockbuster, though Lex suspects that Blockbuster is not who he seems. J'onn is outed by Catwoman and is subsequently defeated by the mass of villains.He was executed organized-crime-style by a villain named Libra, his murder was aired on the internet. He was laid to rest on Mars with a funeral attended by many of Earth's superheroes where Superman himself gave the eulogy saying he was always a friend and someone he could confide in. After everyone else has left the crypt containing John's body, Batman leaves a single Choco cookie on John's coffin.
Recently the Blackest Night has started, the dead have raised in the entire universe and J'onn is one of them. After his resurrection and reclutation to the Black Lantern Corps he went to confront Barry Allen and Hal Jordan, who were talking over Batman's grave being robbed. He approaches them saying that they should be dead and begins to fight the two.
At the end of Blackest Night, Martian Manhunter was among eleven other heroes and villains to be fully resurrected by the power of the White Lantern entity.
After his rebirth Jonn feels the need to revive his own race on Mars soon he discovers that his resurrection drew the attention of the last surviving female green Martian D'Kay D'razz a insane murderer now who attempts to be his mate for the sake of bringing back the Martian race Jonn repulsed by her murderous ways refuses. Soon Jonn discovers that due to his return he kills plant life on Earth for it to be grown on Mars and receives a vision from the White Entity to "burn the green", the forest on Mars.
The Martian Manhunter is one of very few characters who's able to hold his own against Superman, and even fatally harm him, without the aid of kryptonite or other weapons.
In DC's New 52, he is a member of Stormwatch, a secret organisation of powered beings who have protected the Earth for many centuries. While deferring any leadership role, he is a senior member and is often seen investigating on his own outside of the main Stormwatch title, most notably in Green Lantern Corps, where he aides Guy Gardner on Oa.
He also sought out Legion Lost to ascertain who they were and what their purpose was. It was recently revealed that he was the first asked to join the Justice League by the original seven, but his membership ended in a violent battle with the team; what caused this conflict has yet to be revealed.
Many Faces of John Jones
- Martian Manhunter first appeared in Detective Comics vol. 1 #225 (November 1955).
- He has a passion for cookies, especially Oreos. . However due to copyright law, the cookie is often called "Choco" cookies.
- The Martian Manhunter appears to also be the oldest superhero that has appeared on the show. Unless one takes into count that Hawkman has lived several lives then he would be the oldest.
- He never had dessert on Mars. (Absolute Justice, Part 2)
- In Absolute Justice, Part 2, he states "I'm Mars' sole survivor... there's a reason for that." The same quote was said by the Martian Manhunter when fighting Superboy-Prime in the comics.
- Phil Morris father Greg Morris, starred in a first season episode of Superboy (1988-1992) tv series; titled The Invisible People.
- His mere existence is alluded to by Lois in "Spirit"
- He is first called the "Martian Manhunter" in Crimson by Chloe Sullivan, in reference to the events of the previous episode, Labyrinth and by Kara Kent in Cure and officially gained the Martian Manhunter nickname in the Finale, Part 1.
- In the comics, the Martian Manhunter has the powers of flight, shapeshifting, super-speed, super-stamina, telepathy, super-strength, Martian vision (not heat vision, but a vision that releases pressure instead of heat), superhuman senses (nine of them as opposed to the human five), invulnerability, invisibility, intangibility, and possibly the ability to create heat or some other destructive force through his palm.
- The Martian Manhunter is purportedly the last Martian, just as Clark believed himself to be the last Kryptonian. This was confirmed in Absolute Justice by John himself.
- In the hospital scene at the beginning of Bulletproof, Oliver Queen confirms that Martian Manhunter is now a part of the Justice League, although he is more an honorary member until he gets his powers back. This was revealed when Clark asked Oliver: "Since when did he become one of us?", at which point Oliver explains the times when Martian Manhunter helped him get out of trouble..,
- In the comics, he is both genetically and psychologically vulnerable to fire, as much as Clark is to kryptonite.
- The Martian Manhunter defeated three of the escaped Zoners; he killed Aldar who had been moments away from murdering Clark in Seattle, entered Clark's mind in order to stop the phantom called Dr. Hudson who had invaded the Kryptonian's mind, and helped Clark defeat Bizarro by capturing him and bringing him to the "sunny side of Mars".
- In the comics, one of the Martian Manhunter's signature traits is his vulnerability to flame. However, physical fire and intense heat can still injure and kill a Martian.
- While the Martian Manhunter was completely stripped of his powers while saving Clark, this does not explain how they managed to get back to Earth; Clark is unable to fly just yet, and atmospheric reentry would surely have incinerated the Manhunter, though flying through the atmosphere towards the sun would also have incinerated the then-depowered Clark. A likely explanation is that the Manhunter retained his powers just long enough for himself and Clark to return to Earth and the Kent Farm intact, and immediately lost them afterwards. Also, despite losing his powers, he was still able to remain in his human form, this probably means he actually morphs instead of just maintaining a camouflage and no longer can morph back.
- Interestingly, in the comics, years before their time as super-heroes, J'onn posed as an African American farmhand, who befriended a grade school Clark Kent, watching over him during that time. He was forced to quit the Kent's employement due to racial tension from a local Smallville White Supremacy group. 
- In Phantom and in the comics Martian Manhunter proved to be capable of speaking many different languages.
- Martian Manhunter is one of the most powerful entities to appear on Smallville, in fact in the comics J'onn is one of a few characters powerful enough to take on Superman at full strength without the aid of kryptonite. Superman himself has stated that the martian is the most powerful person on the planet, being everything Superman is and much more.
- In the DC Universe Original Animated Movie Justice League: Crisis on Two Earths, Martian Manhunter can be seen in human form when he is escorting the alternate Earth's President Slade's first daughter Rose as a bodyguard. He chooses the form of a African American, as he always does for his human appearance on the show.
- In the Young Justice cartoon series, John Jones chose an African-American appearence similar to the one on Smallville.
- John Jones has teamed up with two of Clark's parents to protect him. He agreed to look after Clark for Kal-El's biological father Jor-El, and then again later worked with Martha Kent (as the Red Queen) to protect Clark from Checkmate.
- He is one of the most recurring members of the Justice League other then Black Canary. 
- He along with Emil, Tess and Chloe are the only Justice League member to have never used an official superhero costume during a live-action scene. He was seen wearing a suit in the online comic, Justice and Doom, however this does not officialy count, as there were no superheroics done in the suit.
- John Jones appeared in 13 episodes (including cameoes), making him the 6th most frequently seen recurring character in the series after Jor-El, Nancy Adams, Brainiac, Emil Hamilton, and Ethan Miller. He also appeared in more episodes than series regular Davis Bloome.
- Martian Manhunter: We're not that different, Kal-El. Like you, I lost my family, came to Earth when my civilization was destroyed. But I've been on this planet a lot longer than you, and have a better understanding of this race. The humans are terrified of what they don't know, and sadly, you and I happen to fall into that category.
- Season Six, Labyrinth, deleted scene.
- Chloe: I did some digging into our favorite Martian Manhunter, but it's just coming up empty.
- Clark: Yeah, but we have another "man hunter" to worry about. Lois.
- Season Six, Crimson
- Martian Manhunter: I had a run-in with the last Phantom... I have to leave Earth's atmosphere to heal.
- Season Six, Phantom
- Clark: When you left here, you were hurt pretty badly... How'd you heal so fast?
- Martian Manhunter: I just had to leave the Earth's atmosphere.
- Season Seven, Bizarro
- Kara: What is he still doing here? I heard red eyes telling you about my father. He's the one who can't be trusted. Ask him to tell you about what he did to my family.
- Martian Manhunter: Your father was a traitor.
- Kara: He's lying. Who are you gonna believe, Clark -- your family... ...or this Martian Manhunter? Guess this family reunion is over.
- Season Seven, Cure
- John Jones: How does it feel to be whole again? (throws football to Clark)
- Clark: (Clark smashes the football with his super-strength) I was dying. You saved me. You brought me to some white light.
- John Jones: The healing effect of the sun brought you back from death. I promised Jor-El that I would only be a watchful guardian. But I could not stand by and let you die.
- Clark: You shouldn't have had to.
- John Jones: Jor-El knew he was sending you on an impossible odyssey. To be given the power of a god, yet exist among humans.
- Clark: Sometimes I feel like I need to be two separate people. Either way, I can't keep expecting you to keep saving me.
- John Jones: Well that was the last time. The burning sun may strengthen you, but it has the opposite effect on me. It stripped me of my powers. We both know, that yours is a greater Clark Kent's destiny.
- Season Eight, Odyssey
- John Jones: I appreciate the assist.
