Superman, nicknamed The Man of Steel, is a fictional character and superhero who first appeared in Action Comics #1 in 1938 and eventually became one of the most popular and well-known comic book icons of all time.

The character, who was created by Jerry Siegel and Joe Shuster for National Comics (today DC Comics), subsequently appeared in various radio serials, television programs, and films. Superman was born Kal-El on the planet Krypton. He was sent to Earth in a rocket by his scientist father Jor-El moments before Krypton exploded, landing on Earth outside the town of Smallville, where he was discovered and adopted by the amiable Jonathan and Martha Kent. As he grew, he discovered that he possessed superhuman powers. When not fighting the forces of evil as Superman, he lives disguised as Clark Kent, a "mild-mannered reporter" for the Daily Planet. Clark's love interest is fellow reporter Lois Lane. In current comics he is married to her.

Synopsis
Superman's abilities and relationships have changed over time. Editors and writers used the process of retroactive continuity, or retcon, to adjust to changes in popular culture, eliminate restrictive segments of the mythos, and permit contemporary storylines. These changes, while significant, permit the retention of the core elements that make Superman an iconic character.

The story of Superman's origin parallels that of other cultural heroes and religious figures [1] who were spirited away as infants from places where they were in danger.


Cover of Action Comics #1, the first appearance of Superman. Art by Joe Shuster.In the legend extant in the early 1960s (and memorably summarized at the start of each episode of the 1950s Adventures of Superman television series[2]), Superman was born on Krypton as Kal-El, the son of Jor-El, a scientist and leader. When Kal-El was two or three years old, Jor-El learned that Krypton was doomed to explode, and he brought this to the attention of Krypton's ruling leaders, the Science Council. Disbelieving Jor-El's prediction, they refused to warn their fellow Kryptonians, and forbade Jor-El to do so. Jor-El promised that neither he nor his wife Lara would leave Krypton, and decided to use the little time remaining to save his son. Moments before Krypton exploded, they launched Kal-El in a rocket ship towards Earth, knowing that Earth's lower gravity and yellow sun would give the boy extraordinary powers.

Kal-El's ship landed in a field near the town of Smallville, and was discovered by Jonathan and Martha Kent; (in the earliest comics, the Kents were named "John" and "Mary"; in a 1942 text novel and the 1950s television series The Adventures of Superman, the Kents were named "Sarah" and "Eben.") They named him Clark, after Martha's maiden name. After formally adopting him, the Kents raised him on their farm through his pre-school years. By the time Clark started school, the Kents had sold their farm and moved into Smallville, where they purchased a general store. During this time, both Clark and the Kents had discovered Clark's amazing powers, and, with Clark realizing the good he could do with his powers, began training their adopted son to use his powers wisely. At the age of eight, Clark adopted the superhero identity Superboy, and began to fight crime, both in the present and in a far future time as a member of the Legion of Super-Heroes. After he graduated from high school and the Kents died, Clark moved to Metropolis to attend Metropolis University. During his junior year, Clark changed his superhero name to Superman. After graduating with a degree in journalism, Clark was hired by the Daily Planet.

In 1986, after the Crisis on Infinite Earths miniseries, DC Comics hired writer/artist John Byrne to recreate the Superman character and retell the Superman mythos, reshaping the previous forty-eight years of stories by putting several new twists on the established mythos. In this "post-Crisis" version, starting with the miniseries The Man of Steel, Superman—like all "post-Crisis" Kryptonians— was created through in-vitro fertilization on Krypton. While a fetus, he escaped Krypton's destruction in a spacecraft (his "birthing matrix" with a rocket engine attached), and landed months later outside of Smallville, by which time he had fully gestated into an infant. Effectively this Superman was "born" on Earth, and was a "son" of Earth as much as Krypton. As in the original version, he was found and adopted by the Kents, and raised like a normal human. In the retelling, Clark's powers developed gradually, beginning with his nigh-invulnerability, and he didn't fly until he was a teenager. After leaving Smallville, he traveled the world before settling in Metropolis, completing his education, and going to work at the Daily Planet. The remodeled Clark did not become a superhero until just before starting work at the Daily Planet, when he prevented an experimental spacecraft from crashing in Metropolis. The Kents were kept alive during Clark's transition to Superman.

In the post-Crisis comics, Clark Kent is presented more as the "real" person, with Superman the secret identity that he presents to the world to prevent his enemies from harming his family or friends. Also post-Crisis, people do not suspect that Superman is hiding his real identity because he wears no mask. The concept that Clark is the real man, and the greater emphasis on his earthly upbringing, is a deliberate reversal of the earlier, pre-Crisis version. As in the original version, Lois Lane is Clark Kent/Superman's love interest. In the early 1990s, Lois and Clark fell in love. Clark soon told her he was Superman, which caused a brief strain in their relationship, but they eventually married, in the mid-1990s special Superman: The Wedding Album.

A 2004 miniseries, Birthright, introduced further changes to Superman's origin story, bringing back some of the pre-Crisis elements eliminated by John Byrne and introducing elements of the Smallville television series.

Clark Kent

Superman and Clark Kent. From Superman (volume 1) #296, February 1976. Art by Curt Swan.Clark Joseph Kent is the civilian secret identity of Superman. Though never receiving the same popular attention as the superheroic alter ego, the personality, idea, and name of Clark Kent have entered into popular culture in their own right, becoming synonymous with secret identities and fronts for ulterior motives and activities.

As first written in the earliest Superman comics, Clark Kent's primary purpose was to fulfill the basic dramatic concept that a costumed hero cannot operate as a costumed hero twenty-four hours a day, or throughout the entirety of a comic book series. As such, Kent acted as little more than a front for Superman's activities. Although his name and history were taken from his early life with his adoptive Earth parents, everything about Kent was staged for the benefit of his alternate identity — he acquired a job as a reporter for the Daily Planet for the convenience of receiving late-breaking news before the general public, providing an excuse for being present at crime scenes and having an occupation where his whereabouts do not have to be strictly accounted for as long as he makes his story deadlines.

However, in order to draw attention away from the correlation between Kent and Superman, Clark Kent adopted a largely passive and introverted personality, applying conservative mannerisms, a higher-pitched voice, and a slight slouch. This personality is typically described as "mild-mannered," perhaps most famously by the opening narration of Max Fleischer's Superman animated theatrical shorts. These traits extended into Kent's wardrobe, typically consisting of a blue business suit, a red necktie, black-rimmed glasses, and combed-back hair.

Kent wears his Superman costume underneath his street clothes, which lends itself to easy transferrence between the two personalities. However, the purpose of this convention outside of fiction is largely dramatic, allowing Kent to rip open his shirt and reveal the familiar "S" insignia when called into action. When in action, Superman usually stores his Clark Kent clothing inside a secret pouch hidden inside of his cape, though some stories have shown him leaving his clothes in some covert location for later retrieval.

In the wake of John Byrne's The Man of Steel reboot of Superman continuity, many traditional aspects of Clark Kent were dropped in favor of a more aggressive personality; Kent became a respected journalist with a more dedicated social life.

In Metropolis, Superman (as Clark Kent) works as a reporter at the Planet, "a great metropolitan newspaper" which allows him to keep track of ongoing events where he might be of help. Largely working on his own, his identity is easily kept secret. Fellow reporter Lois Lane became the object of Clark's/Superman's romantic affection. Lois's affection for Superman and her rejection of Clark's clumsy advances have been a recurring theme in Superman comics, television, and movies.

Various reasons over the decades have been offered for why people haven't suspected Superman and Clark Kent of being one and the same. In the 1970s, one such suggestion was that the lenses of Clark Kent's glasses (made of Kryptonian materials) constantly amplified a low-level super-hypnosis power, thereby creating the illusion of others viewing Clark Kent as a weak and frailer being; however, this reason was abandoned almost as quickly as it was introduced, since it had various flaws (such as stories where Batman would disguise himself as Clark Kent, among others). [3]. Other fans have noted that the disguise is effective presuming Clark is as skilled an actor as Christopher Reeve. The actor's portrayal of Clark in the feature film series was praised for making the disguise's effectiveness creditable to audiences.

Another reason given in the late 1980s was that Superman would vibrate his face slightly so that photographs would only show his features as a blur. However, more recent stories showing Superman being photographed have tended to ignore this factor.

The main means of Superman protecting his secret identity has usually been the physical distinctions between Superman and Clark Kent: Clark Kent is usually shown as wearing conservative clothing, slightly slouching, and speaking in a higher-pitched voice, along with adopting more introverted mannerisms than his heroic alter-ego. Traditionally, Lois Lane and others would often suspect Superman of truly being Clark Kent (and vice-versa), though more recent comics often feature the general public assuming that Superman (because he doesn't wear a mask, suggesting he has nothing to hide) doesn't have a secret identity; in Superman (2nd series) #2 (1987), for example, Lex Luthor was once told the truth, but he dismissed the idea because he could not believe that someone so powerful would want another identity. Also in the modern stories, Lois Lane never suspected the dual identity beyond one time when she visited the Kent farm and caught Superman and Lana Lang together. In the ensuing discussion, she asked about it, but was fooled with an improvised story by the Kents that Superman and Clark grew up together on the farm.

Furthermore, there have been several occasions where Clark and Superman have been seen together, usually staged by Superman as a means of protecting his secret identity; these means have included the use of shape-shifters posing as Superman (as seen in Action Comics #692 when Supergirl posed as Clark Kent so Superman could rescue him from a Civil Defense shelter) and the use of Superman or Clark Kent robots. Occasionally, Superman has requested people to impersonate him as in one Silver Age story in Action Comics #309 which had John F. Kennedy performing such a favor. This inadvertantly created an awkward situation for DC Comics when the story was published coincdentally a month after the President's assassination. The company attempted to stop distribution of the issue to avoid an uncomfortable inferred suggestion that Superman made his request of Kennedy knowing he would soon be dead.

When crises arise, Clark quickly changes into Superman. In the Fleischer animated series of theatrical cartoons, he often ducked into a telephone booth to make the transformation. In the comic books he rarely does so, favoring the Daily Planet's storeroom. As a dramatic plot device, Clark often has to quickly improvise in order to find a way to change unnoticed. For example in the first Christopher Reeve Superman movie, Kent, is comically unable to use a newer, open-kiosk pay phone, so enters a revolving door and changed clothes while spinning within it at superspeed. Thus made invisible, he appeared to enter the building as Kent and exit seconds later as Superman.

[edit]
Kent Family History
In the current Superman continuity, it was revealed that the Kent family in the 19th century were noted abolitionists who assisted the personnel of the Underground Railroad, like Harriet Tubman. The family moved to the territory of Kansas during the infamous Bleeding Kansas period to promote the cause of creating a free state by running a newspaper for the region.

Unfortunately, the family patriarch was murdered by Border Ruffians who wanted to silence him. Furthermore, the sons, Nathaniel and Jeb, argued and had a parting of the ways so deep about slavery that they found themselves on opposing sides of the American Civil War with Jeb fighting with the notorious Confederate guerrilla unit lead by William Quantrill. Nathaniel fought for the North and married a half-Native American woman who gave him a special traditional spiritual symbol that was apparently a forerunner and inspiration for Superman's chest symbol.

After the war, Nathaniel became a sheriff in Smallville, while Jeb became the leader of a group of bandits. Eventually, Jeb discovered he had a son out of wedlock years ago, and allowed him to join his gang. Unfortunately, his son turned out to be a murderous sociopath and Jeb approached his estranged brother to arrange a trap to stop his son.

Unfortunately in springing the trap, the son mortally wounded his father before being killed himself and Jeb fully reconciled with Nate before dying. Nate remained in Smallville and there the Kents have stayed for generations, including Jonathan and Martha Kent, Superman's adoptive parents.


Superman's abilities
Superman possesses extraordinary powers which render him, as stated in the lead-in to the 1950s television series, "faster than a speeding bullet, more powerful than a locomotive, and able to leap tall buildings in a single bound". His powers were relatively limited in the early stories, but grew to become near-godlike by the 1980s. After Byrne's 1986 rewrite, Superman's powers were diminished, though have grown again since then.

His powers include:

Near invulnerability: In the 1940s, "nothing less than a bursting artillery shell could break his skin"; by the 1970s he could fly through a star and shrug off a nuclear blast. In 1986, Superman was somewhat depowered. Still able to withstand artillery shells, lasers, and even nuclear explosions, he would be killed if he flew into a star. His powers have since increased, allowing him to fly into the sun unharmed. Because Superman's powers are partly due to Earth's yellow sun, in Action Comics #782 (October, 2001), during the "Our Worlds at War" series, Superman flies through the sun, which gives him enough strength and power to move an entire planet. In addition, his immune system protects him from toxins and diseases.
Vision-related powers:
X-ray vision: The ability to see through anything except lead. He can see things behind a wall as if the wall were not there, or can "peel back" layer after layer of matter in his mind. Opponents sometimes use lead-lined constructs in an attempt to hide things from Superman. In one "post-Crisis" story this trick backfired when Superman simply scanned the field for lead, which instantly stands out as the only opaque substance to his vision, and found the hidden item easily.
Telescopic vision: The ability to see very distant objects, without violating the laws of physics.
Superman can also see the entire electromagnetic spectrum, including infrared and ultraviolet, allowing him to see in the dark.
Microscopic vision: The ability to see extremely small objects and images.
Heat Vision: The ability to apply heat to a target by staring intensely at it with the conscious act of activating his power. Visually, the power is typically depicted as twin laser beams firing from the eyes. These beams can be made invisible, allowing Superman to work undetected.
Super hypnotism: Pre-Crisis, Superman had the ability to hypnotize others at will. This ability was dropped in the modern comics. One late 1970s story, attempting to explain the effectiveness of Superman's disguise as Clark Kent, suggested that his super-hypnotism, aided by his Clark Kent glasses, worked continually to make others see him as a thin, mild mannered man, not an athlete in a suit, and even included photographs of himself. However, this theory presented numerous flaws, such as various stories where Batman would disguise himself as Clark Kent; it also failed to account for anyone studying Kent's build from behind, let alone how the illusion could work on a video camera or whenever Kent was performing his job as a TV news anchorman. For these reasons, this explanation for his disguise's effectiveness was dropped, in favor of the traditional "suspension of disbelief" status quo.
Super-hearing: The ability to hear any sound at any volume or pitch. The only Earth creature who can detect sounds at the frequency he can is a Blue Whale (0.01-200,000 Hz).
Super voice: Superman is a master ventriloquist; he used this once to rescue Lois from criminals. He is also a brilliant mimic, able to impersonate human voices or animal sounds. Pre-Crisis, Superman also possessed the power of "super-ventriloquism," or the ability to pitch his voice across vast distances, which he would use in combination with his super-hearing as a means of communication.
The power of flight, by force of will, which also allows him to maneuver precisely in any direction, as well as hover. Originally, Superman could jump 1/8 of a mile, and only acquired the ability to fly in the early 1940s, when the first Superman animated films were being produced and super-jumping proved to not look very impressive on theatre screens.
Super breath: The ability to create hurricane force winds by blowing, and to chill his breath to freeze a target (this latter ability has also been called "freeze breath").
Super speed: The ability to move at an incredible speed, like the Flash. This includes running, but flying is less strenuous and more versatile. The earliest Superman ran at a mere 30 miles per hour, but quickly became much faster; by the 1950s, Superman became capable of flying through space at faster-than-light speeds, as well as travel through time. Post-Crisis, his top speed seems to be at or near the speed of light, and he can no longer travel through time under his own power.
Super strength: The exact magnitude of Superman's strength is unknown, it is generally accepted that his strength easily surpasses the capacity to lift 100 tons, but how much more is not known exactly. This is because Superman's strength, like his other powers, has fluctuated over time, with the Man of Steel being at times able to shift a planet from its orbit. One figure for Superman's strength is 800,000 tons (pre-The Death of Superman story arc).
Super intellect: In the earliest comics, Kryptonians were endowed with genius-level intellects on their native planet. Eventually, this superior mental talent was altered to being another superpower gained only under the influence of a yellow sun (though Krypton still possessed an advanced educational and intellectual state). In the Silver Age comics, Superman possessed the intelligence of a collection of the world's greatest minds. He had a computer-like brain, which gave him total recall and the ability to speak all earthly languages and even most alien ones. His skill with science and mathematics were beyond human comprehension. However, over time, this power as a whole has been scaled back, if not eliminated, in current comics. The ability is evident in The New Batman-Superman Adventures and the Justice League cartoon series, though.
From the 1940s through the early 1980s, Superman's powers were nearly unlimited: he could travel millions of light-years in brief periods of time; he could dive into stars unharmed; he could travel through time by moving at speeds faster than light; and he could move planets and lift any weight. He could even vibrate his body so fast, the vibrations rendered him "invisible" to the human eye.

When Superman was revamped in 1986, he became more vulnerable and was no longer omnipotent. As in the original series, writers again gradually increased his powers. Since "coming back to life" during The Death of Superman story arc, Superman can once again survive nuclear blasts, though they leave him wounded and weakened, and he can no longer fly faster than the speed of light or travel through time under his own power. His strength too has increased, to the point of allowing him to move mountains again.


How Superman's powers work
Superman's powers are derived from his Kryptonian biology and Earth's sun (a yellow star), and are likely increased by Earth's lesser gravity (versus Krypton's higher gravity).

Various explanations have been offered over the years explaining how Superman's powers work. In the earliest comics, all Kryptonians were said to possess superpowers while on Krypton. By the late 1940s, this was changed to Kryptonians only gaining superpowers when under a lower gravity environment such as Earth's. In the early 1960s, after the introduction of Supergirl, this was amended to Kryptonians deriving their powers from mainly exposure to a yellow sun (vs. Krypton's red sun), as well as to a much lesser degree Earth's lower gravity; when under a red sun, a Kryptonian would be completely powerless, even if it was a low-gravity environment. John Byrne in his 1986 reboot suggested that Superman's powers were telekinetic in their functioning (in addition to the traditional yellow sun explanation).

One such "scientific" explanation used in various recent analyses of how Superman's powers might work is as follows:

Kryptonian mitochondria absorb certain wavelengths of the radiation emitted by solar fusion. Under a red sun, this yields increased abilities, which are multiplied a thousand-fold by a yellow sun. The solar energy supplements respiration, such that when cellular materials (perhaps Kryptonian ATP) combine with glucose, they produce abilities beyond those of humans under a yellow sun.

"K-ATP" is produced rapidly, enabling a Kryptonian to build up reserves that permit days of super-powered activity in the absence of sunlight. In addition, Krypton's gravity was 50-100 times stronger than Earth's, so Kryptonian cells are also much stronger and denser than a human's.

Under a yellow sun, other factors contribute to invulnerability. First, cell membranes and organelles become more resistant to harm; secondly, a bioelectric field surrounds the cells, making them thousands of times tougher. This "aura" surrounds Superman's epidermis and teeth, and possibly his nails as well. His hair is invulnerable, too. Superman has been shown shaving and presumably cutting his hair by reflecting his heat vision off of a piece of curved, reflective metal from the rocket in which he landed. In fact, any type of reflective metal will work, as shown in Action Comics #663 (page 11). When his cells become "supercharged" under a yellow sun, a Kryptonian becomes super-powered. He is invulnerable to forces under 1 kt., and is harmed only by repeated blows of over 1 mt. His brain and nervous system keep up with his enhanced speed, as they too are amplified by K-ATP.

Superman's other senses are less linked to solar energy than his strength and speed. Due to Earth's denser air, he can hear things no human can. Solar energy magnifies its accuracy, allowing him to fine-tune it. His taste, smell, and touch are equally acute. He sees all wavelengths, from radio to X-rays, allowing him to detect thermal trails and other "invisible" things.

Superman's cells store vast amounts of yellow solar energy. He replenishes his supply even on cloudy days, and weakens only after a week without sunlight. Near a red sun, his powers would fail faster. Red solar radiation creates a chemical which does not lead to the super energy produced by K-ATP. Kryptonite exposure also stops the process that converts yellow sunlight into superpowers, leaving Superman immediately weakened. His powers return quickly once the kryptonite is removed. In recent comics, Superman seems to be slowly building up immunity to kryptonite, and it is possible that its effect is in part psychological. In several late 1980s and early 1990s storylines, Kryptonians demonstrated a biological and possibly psychological link to their planet, which may explain the intense effects Superman experiences when in the presence of different types of kryptonite. In one of the storylines' issues, however, Jor-El explained to Lara that he eliminated the particular weakness that connects Kryptonians to their planet from Kal-El while he was still in his birthing matrix, which could also mean that kryptonite effects might be a result of the lack of connection to Superman's home planet.

Earlier in his life, as in his battle with Doomsday, Superman's solar energy supply was depleted by exertion. More recent exertions caused less of a power drain, suggesting that he is now either storing more energy, or growing stronger under the yellow sun. It is unknown whether higher energy stars might increase his powers even more.

Weaknesses
There are some things Superman cannot do. Since he is not human, he cannot donate blood, tissue, or organs. Procedures like surgery are impossible without special equipment. He does not sweat under earthly conditions, as no temperatures are high enough to make him secrete liquid to cool himself down. The issue of whether Superman can father children is humorously explored in the movie Mallrats, as well as in the essay Man of Steel, Woman of Kleenex by sci-fi author Larry Niven (originally published in his 1971 collection All the Myriad Ways.). On the final episode of the television series Lois and Clark: The New Adventures of Superman, the pair adopted a child who, like Clark, came from mysterious origins. But historically, many stories have established that Superman can in some manner have progeny.

As a Kryptonian, he has one specific area of vulnerability. Since Krypton was destroyed, its remains (rendered radioactive by the explosion) have been spreading throughout the universe as kryptonite, a crystalline substance which has several major variants:

Green kryptonite is fatal to Kryptonians exposed to it for a sufficient period of time, and causes immediate intense pain to Kryptonians upon exposure. It can also give humans cancer, as in the case of Lex Luthor.
Red kryptonite has unpredictable effects on Kryptonians' physical or mental states, such as splitting Superman in two, inducing amnesia, turning him into a giant, etc. The effects wear off in 24-48 hours, after which a Kryptonian becomes immune to that particular piece. In the television series Smallville, red kryptonite causes the repressed, more violent and less conscientious part of his personality to gain control; on Lois and Clark, red kryptonite had three different effects: one inducing a sense of apathy, one transferring all powers to another being, and one amplifying his powers by seven times. In the "Tower of Babel" story arc in the JLA comic book, a piece of synthetic red kryptonite made his skin invisible, allowing the sun to supercharge his cells past their normal limit and cause great pain to Superman himself.
Gold kryptonite permanently removes a Kryptonian's superpowers. In Action Comics #823 (March, 2005), yellow or gold synthetic Kryptonite was used to give a frail man incredible size and strength, rivaling that of Superboy AND Superman. This particular kryptonite was apparently uniquely different from regular Gold Kryptonite, in that it was part of a plan by Gog to weaken and age Superman.
Blue kryptonite affects only Bizarros, in the same way that green kryptonite affects only Kryptonians. In some story arcs, it can also counteract the effects of red kryptonite.
White kryptonite affects (and kills) only plant life.
Jewel kryptonite gave Phantom Zone prisoners amplified mental powers.
Slow Kryptonite is a modified variety of Green Kryptonite produced by a Terran scientist that decelerates the speed of nerve impulses, and movements of both Kryptonians and Terrans.
X-Kryptonite was created by Supergirl while she was trying to find a cure for Green Kryptonite. It gives Terrans, or at least Terran cats, Kryptonian style powers for a limited time. See also: Streaky the Supercat.
Anti-Kryptonite affected non-superpowered Kryptonians in the same way that Green Kryptonite affected superpowered Kryptonians. This form of kryptonite was what killed the residents of Argo City.
For more information on kryptonite, see also: Kryptonite.

Other variants were introduced sporadically, but after the 1986 John Byrne reboot, all versions except for green were retconned out of existence. Since that time, an updated version of red kryptonite was reintroduced into the comics. Recently, with the destruction of the Kryptonite meteor in Superman/Batman, large quantites of kryptonite have fallen to earth; new forms beyond the red and green are believed to be amongst them, however, only Blue Kryptonite has been seen in addition to the previously known types so far. The effects of the new Blue Kryptonite were unknown until recently, when, in a Superman/Batman comic, a Bizarro-Batman (self-proclaimed "Batzarro") was shown giving a Blue Kryptonite ring to Bizarro, causing Bizarro to actually speak normally and intelligently while still being "postively lethal" to him.

Kryptonians are also vulnerable to magical and psychic effects, although they are no more detrimentally affected by such effects than a normal human would be.


Equipment
Given his abilities, personal equipment plays less of a role for Superman than for other superheroes.

The Fortress of Solitude, located in the Arctic in the pre-Crisis version of the mythos and (until recently when it was moved to the Amazon) in Antarctica in the post-Crisis version, serves as Superman's secret base of operations. The Fortress acts as Superman's personal getaway, although it has communications equipment for urgent messages. While various 1940s comics made mention of Superman having a "mountain retreat," the Fortress in its familiar sense was first introduced in the comics in 1958.

Pre-Crisis, the Fortress included laboratories, a private zoo of alien animals, a room for communication with the Phantom Zone with a projector to place or remove people from it, a Krypton memorial, a trophy room, and a gym with custom exercise equipment. It also had tribute rooms to personal friends like Lois Lane, Jimmy Olsen, Batman, and Clark Kent (to throw off suspicion about his secret identity by visitors unfamiliar with it), where Superman prepared special gifts for each in the event of his death. Most importantly, the Fortress was where Superman stored the bottle city of Kandor, which pre-Crisis, was a Kryptonian city shrunken and stolen by Brainiac prior to the planet's destruction. For years, Superman worked to reverse the city's condition, while also enjoying the opportunity to visit a native community where he was an honored guest.

Post-Crisis, the Fortress was originally created by the Kryptonian artifact, the Eradicator, when Superman tried to dispose of it in Antarctica. The device created the Fortress which contains much of Krypton's technology, including artificially intelligent robots. Superman and fellow superhero Steel encased the Fortress in a tesseract, permitting the Man of Steel to carry the Fortress wherever he travels. Superman also stores in the Fortress various equipment, weapons, and vehicles of Kryptonian design, including a large fighting mecha called a battlesuit and a means of accessing the Phantom Zone.

A trademark of the Fortress in all of its incarnations is a memorial statue of his Kryptonian parents, Jor-El and Lara, holding up a globe of the planet Krypton.

Superman, in the pre-Crisis comics, also had androids that could impersonate himself (as both Superman and as Clark Kent). He largely abandoned them when Earth's pollution began to interfere with their functions. Post-Crisis, Superman at one time had built various Superman robots; however, all but one were destroyed, with the sole remaining robot currently being kept on duty at the Fortress of Solitude. This one remaining robot was destroyed by superheroine Donna Troy, at the expense of her own life, though she was soon resurrected.

For situations involving kryptonite, Superman in the original comics had a collection of lead-lined suits for protection. If his powers were disabled or he needed stronger protection, Superman also had his "Supermobile," a small flying car-like vehicle which could fly anywhere and use its powerful waldo arms to handle outside objects.

Superman's costume was created by Ma Kent; pre-Crisis, she created it out of the blankets from the rocket that brought him to Earth. Said blankets, like everything else from Krypton under a yellow sun environment such as Earth's, shared Clark's invulnerability. His armor-like costume could also protect others that wore it. While carrying passengers in flight, Superman would wrap them in his cape to protect them from air friction. In the post-Crisis comics, his costume is invulnerable because of the bioelectric field that his cells produce (see how it works).

In the original comics, Clark's eyeglass lenses were made from two small rounded pieces of glass from his spaceship. Since they were of Kryptonian origin, Clark could fire his heat vision through them without melting them (in contrast, the post-Crisis Clark has to lift his glasses [made of ordinary materials] off his eyes when he uses his heat vision). Superman also sometimes carries spare change in his hollowed-out belt buckle, which also doubles as a Justice League communication device. In recent comics (as seen in Superman/Batman), the belt buckle was made of lead and stored a fairly safe synthetic form of kryptonite for Clark to use. When he had Kandor in his possession in the pre-Crisis comics, all of these improvisations were supplemented by the products of the professional tailors and lenscrafters available in the bottle city.

Personality and character
Originally, Superman's personality could be rough and destructive. In one really early story in which the government would not help maintain low income areas unless a disaster occurred, Superman went on a rampage and created one. Superman is also nearly always portrayed as having had some hand in WWII, when the timeline permits. As superhero stories became more oriented toward young readers, the writers moved toward his better known "boy scout" persona. Even so, Superman's capacity for a violent anger is a key element to many of the most dramatic moments in his appearances, since it is this sort of telling snapshot into his psyche that allows readers and watchers to see that Superman's goodness is not inherent to his being, but learned, like it is with us.

This is why, despite the emphasis on Superman having powers "far beyond those of mortal men," his name referred also to his goodness. While Jor-El sent Kal-El to Earth because he felt the human race had the capacity to be great and good if they wished to be, it is clear that Kal-El chose to become Superman and a force for good. The education he received on the family farm is the most potent symbol for 'old fashioned values' one can conjure, and this helps ground the character. He seems out of place and out of touch with his world because he is, in fact, the product of 'better times' more than the real world.

Superman has been willing to lay down his life or sacrifice his powers for good. He rescues cats from trees and participates in community fund-raisers. He often acts behind the scenes and lets others receive the credit. His modesty and humility catches his foes and critics off-guard, as they do not understand why he spends his life helping others and doing good.

Recent writers have attempted to deepen Superman's persona and provide a rationale for his goodness. They reveal his self-doubts, and his fear that he might abuse his powers and become a monster, subject to no one. He therefore makes it a point of submitting to authority, helping him to feel a restraint on his actions. In an extraordinary show of mutual respect, Superman has given Batman a ring of green kryptonite, so that if he ever lost his reason, posing a danger to himself or to humans, Batman could use the ring to defeat him.

This line of thinking, that Superman is a hero as deeply conflicted with his gifts as Batman is with his past, is key to the modern interpretation of Superman not as a better man, but what is best in man. It is also important that Superman often struggles with vast social issues in his fiction, including tackling world hunger, unsuccessfully, in a short wide-panel 1990s graphic novel called Peace on Earth. (with artwork by Alex Ross). Through these conflicts, discussions of good and evil are formed, as Superman struggles with restraint in the face of bigotry, avarice, and cruelty. In this manner, Superman's excessive arsenal of powers is rendered secondary to his ability to convince others to act.

This was a further motivation for Superman becoming a reporter, for it is then possible that his physical abilities give him no unfair advantage in a field where the critical skills are intellectual (although his editor, Perry White, praised him in Superman: The Movie as "the fastest typist I have ever seen"). He writes fiction in his spare time, publishing two books, "The Janus Contract" and "Under a Yellow Sun".

Far from a perfect individual, Superman is often pictured with a sense of childish innocence mixed with patriarchal restraint. He is also a man with an incredible depth of feeling, since he lives within his own mind as much as he does in the reality of society, often struggling with the differences between the right answer and the practical one. In many ways, Superman is truly one of the most "human" heroes conceived, since he responds to emotional grief in stark contrast to the way he shrugs off bullets, bombs, and death-rays. Superman's daily martyrdom is reflected tellingly in print during his reappearance in the 1996 miniseries Kingdom Come, where he is pictured as a bearded carpenter with a long beam of wood across his back, mirroring a Christ-like image of a man who gave himself for a world that, in that storyline, did not love him.

Superman's "lily white" persona has been mocked, ridiculed, and spoofed, especially in recent comic book history, when "grim and gritty" comics dominated the market. Superman may seem old-fashioned and even quaint compared to the "dark avengers" who currently command the lion's share of the market, and this is intentional. Superman fights fair long after both sides have begun swinging below the belt, knowing that his vast powers require him to act with equal restraint. On several recent occasions, Batman has faced Superman, and Batman has served as a foil to Superman's goodness; Batman, in his more recent incarnations, won't hesitate to use guile or underhanded tactics to gain an advantage, while Superman will be overly hesitant to use his natural gifts as an unfair edge. Indeed, Batman has undergone an increasingly dark makeover. However, Superman continues to be a driving force in the medium after more than sixty years. He has been seen as an "Old School" hero, valuing the safety in others, keeping his clean image made his comics a sharp contrast to Marvel or Image comics, with ruthless anti-heroes. Superman is seen as a more conservative hero, along with Hawkman and Hal Jordan (pre-Parallax era), as opposed to the more liberal heroes like Batman and Green Arrow.

History

Cover of Superman #14, dated January-February 1942. Art by Fred Ray.Superman was created by Jerry Siegel and Joe Shuster not as a hero, but as a villain. Their short story "The Reign Of The Superman" concerned a bald-headed villain bent on dominating the world. The story did not sell, forcing the two to reposition their character on the right side of the law. In 1935, their Superman story was again rejected, but DC Comics printed another of their creations, Dr. Occult, who made his first appearance in New Fun Comics #6, October 1935.

The revised Superman first appeared in Action Comics #1, June 1938. Siegel and Shuster sold the rights to the company for $130. DC copied the character without remuneration to the creators, while suing other companies for copying it. The Saturday Evening Post reported in 1941 that the pair was being paid $75,000 each per year, still a fraction of DC's Superman profits. In 1946, when Siegel and Shuster sued for more money, DC fired them, prompting a legal battle that ended in 1948, when they accepted $200,000 and signed away any further claim to Superman or any character created from him. DC soon took Siegel's and Shuster's names off the byline.

During a multimedia career spanning over sixty years, Superman has starred in every imaginable situation, throughout the universe, and in many eras of history. Facing myriad perils, his powers have increased to the point that he is nearly omnipotent. This poses a challenge for writers: "How does one write about a character who is nearly as powerful as God?" (Superman's Kryptonian name, Kal-El, resembles the Hebrew words for "all that God is") This problem contributed to a decline in Superman's popularity, especially during the 1960s and 1970s, when Marvel Comics brought a new level of character development to mainstream comic books. By the early 1980s, DC Comics had decided that a major change was needed to make Superman more appealing to current audiences. Writer-artist John Byrne joined Superman and re-started with his The Man of Steel retelling of his origin. This 1986 reboot brought substantial changes to the character and met huge success at the time, being one of the top-selling books. The re-launch of Superman comic books returned the character to the mainstream, again in the forefront of DC's titles.

Some fans debated whether the more drastic changes were necessary, and some of the more traditional historical elements Byrne removed from the backstory were later restored. Byrne himself quit the books after a few years because he felt DC was not supporting the changes he made. But Byrne's changes became the template for Superman's origin and characterization for almost two decades. Most notably, his alterations to Lex Luthor, altering him from a scientific oriented villain to a businessman remain to this day.

Two alterations have had long-term effects. In the epic The Death of Superman storyline, the hero apparently died at the hands of supervillain Doomsday. He returned from the dead, though his "death" gave rise to a number of new characters and storylines. In 1996, Superman (or rather, Clark Kent) finally married Lois Lane, and the two have had a happy marriage... so far. Future editorial changes to the series may reverse some or all of these changes.

In 2003, DC Comics released a 12-issue maxiseries titled Superman: Birthright, written by Mark Waid and penciled by Lenil Francis Yu; this was made into a retcon of Superman's post-crisis origin, replacing Byrne's version, but yet using many elements from that version, along with elements that subtly tie into the Smallville television show.


Supporting characters
Familiar supporting characters in the Superman mythos include:

Lois Lane: Superman's love interest, who is traditionally portrayed as being indifferent to Clark, but in love with Superman; in current comics, Clark and Lois are married. Actresses portraying Lois have included Noel Neill, Phyllis Coates, Margot Kidder, Teri Hatcher, and Erica Durance.
Jimmy Olsen: Daily Planet photographer who often works with Lois and Clark, and has become a good friend to both. Jimmy is also known to have associated with Superman, earning him the nickname "Superman's Pal."
Perry White: Editor-in-chief of the Daily Planet. Is noted for his trademark cigars and gruff but caring demeanor with his staff.
Lana Lang: Clark Kent's childhood friend from Smallville. Pre-Crisis, Lana often suspected Clark of being Superboy; post-Crisis, Clark told Lana about his powers in high school before leaving Smallville. Later, Lana married Pete Ross, and had a son named Clark; Lana and Pete later divorced.
Pete Ross: Clark Kent's childhood friend from Smallville. Pre-Crisis, Pete accidentially discovered Clark was really Superboy, but kept the knowledge a secret from Clark. Post-Crisis, he didn't learn Clark's secret until much later, and had married Lana Lang, with whom he had a son named Clark; Lana and Pete later divorced. Pete Ross was recently revealed to be a villain named Ruin.
Lori Lemaris: A mermaid who Clark Kent dated while attending Metropolis University, and was the first person he proposed marriage to (though Lori turned him down). Lori returned to current comic continuity as a prelude to Clark and Lois's short-lived breakup in a 1996 storyline.
Jonathan and Martha Kent: Superman's foster parents who adopted and raised him after he landed on Earth. Often referred to as Ma and Pa Kent.
Supergirl: Pre-Crisis, Supergirl was Kara Zor-El, Superman's cousin from Argo City, a city that for a time had survived the destruction of Krypton until its residents died of kryptonite radiation. Post-Crisis, several unrelated versions of Supergirl have been introduced. In recent issues of Superman/Batman, a new "Supergirl from Krypton" (looking very much like the original) arrived on Earth.
Steel: An engineer genius named John Henry Irons who created a high-tech, mechanized suit of armor to fight crime in, after Superman's death in the Death of Superman storyline, and still serves as a superhero today.
Superboy: Pre-Crisis, Superboy was Superman's superhero identity as a teenager. Post-Crisis, Superboy is a clone, originally thought to have been of Superman, that was created after Superman died during the Death of Superman storyline. He soon found out that he was a clone of Paul Westfield. However, recently in Teen Titans, it was revealed that Superboy is actually a hybrid of human and Kryptonian DNA, with the human DNA coming from Lex Luthor. The Westfield connection has not been re-explained since.
Krypto: Pre-Crisis, Krypto was the El family's pet dog on Krypton, who eventually wound up on Earth and gained superpowers like Superman's. Recent comics have introduced an updated version of Krypto; this version currently lives with Superboy (Kon-El).
The Justice League of America: a team of superheroes of which Superman is a member and often the leader. Other notable JLA members include Batman, Wonder Woman, the Flash, and Green Lantern.
In Metropolis, Superman enjoys a close relationship with the police department. This especially applies to the Special Crimes Unit (SCU), a police unit that deals with superpowered threats, led by Captain Margaret Sawyer, one of the few openly gay characters in mainstream superhero comics today.

There have been a number of characters called Superboy. The original Superboy, introduced in 1944's More Fun Comics #101, represented "the adventures of Superman when he was a boy." This Superboy is no longer in publication, as post-Crisis continuity deemed that Clark Kent did not become a superhero until he reached adulthood. A new Superboy character who is a clone of Superman was created in the early 1990s; adventures featuring this character continue to be published. The Superboy name has also been the name of denizens of other dimensions, such as one from a "pocket universe" parallel dimension in the late 1980s post-Crisis Superman comics, and several individuals the current Superboy encountered during his trip through Hypertime (one of those essentially being an exact double of the pre-Crisis Superboy). See also: Superboy.

Pre-Crisis, Superman's foster parents, Jonathan and Martha Kent, died in the summer after his high school graduation; post-Crisis, the Kents are alive and well and are regularly visited by Clark, who relies on them for advice in difficult times.


Villains
Superman also has a rogues gallery of supervillain enemies, including:

Lex Luthor: Superman's most well-known enemy. Pre-Crisis, Luthor was a rogue scientific genius with a personal vendetta against Superman. Post-Crisis, Luthor is portrayed as a powerful but corrupt CEO of a conglomerate called LexCorp, but still has the same hatred of Superman.
Darkseid: A cruel and merciless alien who rules the planet Apokolips and only deals with Superman when it benefits his own agenda. Not originally created as a Superman villain, but by Jack Kirby for his New Gods series.
Bizarro: An imperfect duplicate of Superman. Pre-Crisis, Bizarro was created by an imperfect duplicator ray; post-Crisis, he originally was a failed experiment of Lex Luthor's. More recently, a newer version similar to the pre-Crisis version was reintroduced.
Metallo: A cyborg criminal who prefers using kryptonite as his power source, which makes him a deadly threat to Superman.
Mr. Mxyzptlk: A being from the fifth dimension with magical powers who delights in tormenting Superman and traditionally could only be made to return to his native dimension by being made to say or spell his own name backwards.
Brainiac: An alien scientist from the planet Colu, intent on conquring Earth; pre-Crisis, Brainiac was portrayed as being an android. Post-Crisis, he was portrayed as a circus mentalist named Milton Fine who was possessed by a Coluian intelligence. During "The Doomsday Wars" storyline, however, Fine's body was destroyed and Brainiac once more inhabited a robotic body.
Phantom Zone criminals: Pre-Crisis, these were Kryptonian criminals imprisoned in a dimension called the "Phantom Zone", in which they only existed in a ghostlike form; this allowed them to survive the destruction of Krypton. Various such criminals would sometimes escape and attack Superman.
General Zod: Pre-Crisis, Zod was one of the main Phantom Zone criminals that fought with Superman. Post-Crisis, Zod was first depicted as a Phantom Zone criminal that Superman encountered in an alternate dimension; eventually, this Zod was killed by Superman with kryptonite. A second version of Zod was later introduced as a product of Soviet genetic engineering, surgically altered to mimic Superman.
Parasite: A janitor (Maxwell Jensen pre-Crisis; Rudy Jones post-Crisis) who had been mutated into a super-powered man who could absorb the powers, strength, and memories of any organic being, and wanted Superman's power for himself.
Intergang: A nationwide organized crime syndicate armed with weapons supplied in part by Darkseid.
Doomsday: A mindless, impossibly powerful, raging monster that killed Superman during the Death of Superman storyline. During the Last Laugh storyline, a "jokerized" Doomsday that had been reengineered with changes from Superman's DNA attained intelligence; Darkseid and Lex apparently had a deal to make clones of Doomsday. A version of Doomsday seen recently attained more than just the ability to talk, but the ability to reason and experience emotion, which ultimately turned him from an evil monster to a hero that saved Superman in the present and in an alternate future.
Imperiex: An all-powerful force of nature whose purpose is destroying galaxies. Eventually, Superman, Steel, and Darkseid stopped Imperiex by using Doomsday as an ally, along with a powerful weapon called the Entropy Aegis.
Toyman: An insane criminal who uses special equipment and weapons based on toys.
The Cyborg Superman: A reanimated astronaut cyborg who briefly impersonated Superman after his death, and also destroyed Green Lantern Hal Jordan's home of Coast City.
Gog: A human from the future who masters time travel, and hates Superman for allowing his parents to die.

Cultural influences

USPS stamp honoring Superman's first appearanceSome people incorrectly believe that Superman is partly based on philosopher Friedrich Nietzsche’s Übermensch, which literally translates to “overman” but could also mean “superman.” Nietzshe’s Übermensch is any person who rejects unfounded thinking. Some people argue that kryptonians’ mental and physical superiority when compared to humans is meant to indicate that they are racially better, as eugenics would teach. Others say that kryptonian super powers are merely a contrivance and the more advanced world of Krypton represents what the people of Earth can achieve in our future. This theory is bolstered by the fact that our own sun is getting older and will someday turn red, so if the universe with Superman’s physics were to apply to reality then someday Earth would produce humans who, when energized by a yellow sun, would likely have the same powers as Superman.

Superman is believed to have been inspired in part by Philip Wylie's 1930 science fiction novel Gladiator, about a man whose superhuman strength inspires him to help the human race, but who is instead spurned by humanity precisely because of his power. Other sources cited as inspirations include Doc Savage and The Shadow. Superman is a staple of American pop culture.

DC Comics has trademarked variations on the "super" theme, such as "superdog" and "supergal", to circumvent parody or product confusion. Nevertheless, a great many imitations and parodies of Superman have appeared over the years. One of the first Superman-like characters to emerge, Fawcett Comics' Captain Marvel, sparked legal action because of its similarities to Superman. Well-known spoofs of Superman include Mighty Mouse, Underdog, Super Grover, and Super Goof.

In the 1990s, comic book artist and writer Rob Liefeld created a Superman pastiche and starred him in his own comic book series, Supreme. The series, published by Liefeld's Awesome Comics, sold moderately well at first, but sales dwindled until the series was taken over with issue #41 by writer Alan Moore. Moore produced 22 issues of Supreme that paid homage to the classic "Silver Age" Superman.

Comedian Jerry Seinfeld expressed his fandom of Superman in several ways. On the Seinfeld TV show, a Superman statue sat on the stereo in Jerry's livingroom, and a Superman refrigerator magnet was always visible in his kitchen. Jerry affectionately addressed some of his girlfriends as "Lois Lane". Seinfeld is also famous for having a Superman reference in every episode. In 1998, an American Express commercial featured real-life Jerry Seinfeld and an animated Superman as buddies holding a running conversation around New York City, (directed by David Kellogg).

One of the few Superman-like characters that DC Comics allowed to stand without litigation is Hyperion, from Marvel Comics's superhero team, Squadron Supreme. The Squadron Supreme was created to do unofficial JLA/Avengers crossovers; the "new" characters were thinly veiled versions of their DC JLA counterparts. Hyperion stood in for Superman, the Whizzer for The Flash, etc. DC in turn introduced the "Assemblers of Angar", a thinly-veiled Avengers pastiche. Hyperion has been revamped in a new Marvel series, Supreme Power, giving a new take on the Superman mythology.

In 2004, local authorities in Sweden refused to allow a child to be named Stålmannen, which means Superman (literally: The Man of Steel). The Swedish parliament was considering at the time whether to intervene and overrule the initial judgement.[4]
