Superman: Earth One

Clark Kent arrives on a train in Metropolis, and rents a room at a hotel. The next morning he tries out several jobs: pro footballer, Major League baseball player, and positions in a scientific research company, and in financial services and media industries. Clark realizes he can do anything as each company wants to hire him. He calls his mother and tells her what has happened, to which she replies that she would be happy with his choice of occupation. His last job stop is at the Daily Planet newspaper, where he meets Perry White, James "Jim" Olsen, and Lois Lane.

However, upon hearing that the Daily Planet and the wider newspaper industry are in decline, Clark decides not to apply for the job, dumps his application, and flies into space. He thinks upon his history, and how his adoptive parents, Martha and Jonathan Kent, told him how they found him while hiking through woodland. The Kents saw a spaceship fly past them and crash, creating a sonic boom in its wake. They checked the wreckage for survivors, found a baby boy, and left with the infant and a small fragment of the wreckage. Some time later, the Kents decided to keep the child. Shortly after this, the US government and military arrive at the crash site. The Kents kept a small fragment of debris from the ship and learned of its, and the child's, extraterrestrial origins. Back in the narrative present, Clark talks to his late father's grave and says he feels incapable of being a superhero as he has already conformed to human society. Instead, he decides to begin a career and hopes that his father would accept that.

The next day, and twenty years after it crashed, Major Sandra Lee, a soldier working at a US Military base on advanced technology, revisits the crashed spaceship, which has regenerated its damaged and lost parts. The scientists working there have found symbols inside the atomic structure of the ship. Clark discovers his apartment is on fire, and quickly enters the building to recover the fragment of spacecraft and a red and blue outfit his mother made for him from the cloth he was wrapped in as an infant. Alone, Clark checks the fragment with his enhanced vision when he is hit with energy, becomes unconscious, and falls from the sky. The fragment talks and connects itself back to the ship in order to download more information. Just then, an invading alien force arrives and attacks Earth's major cities. The military quickly mobilizes, but the alien attack ships defeat Earth's fighter jets. Jim and Lois are almost killed because Jim wants to take photographs of the invasion. Clark, still unconscious, is given information he could not previously remember: the last moments of his homeworld, the planet Krypton.

Clark, born as Kal-El, is the son of Jor-El and Lara Lor-Van, who waited until the last minute to dispatch him so that the shockwaves would hide his escape. The alien armada leader, Tyrell, reveals himself to the Earth but does not reveal his identity and purpose. He issues an ultimatum: the Earth will be destroyed, and millions will die if someone Tyrell has been looking for does not surrender to him. Major Lee and the scientists agree that the person for whom Tyrell is looking was in the crashed ship. Clark tries to attack the aliens without revealing himself, but Jim's photographs show a human-shaped red and blue blur. Clark goes for help at the research company that was about to employ him, but he finds that it is corrupt. Tyrell notices Jim taking pictures and almost kills him until Clark, who can no longer stand by and watch, destroys a robot. Tyrell is now aware of Clark's presence on Earth and prepares to increase the ferocity of his attack. Clark looks at his outfit, remembers wondering why there was no mask and his mother asking whether he wants to hide for the rest of his life, and his adoptive father coining the name "Superman". Clark decides to wear the outfit and reveals himself to the world as Superman.

Superman lands and starts destroying the alien robots and ships, and Tyrell reveals himself. He proves to be Superman's physical match, and says that Krypton's destruction was no accident but was an assassination. Tyrell originates from the planet Dheron. Krypton and Dheron were bitter enemies that fought several wars, which ended when a man whose identity is not-yet revealed provided a war machine, designed to destroy Krypton's core. Although Krypton was destroyed, a scientist's son escaped, and a mission with whom Tyrell had been charged―to find and kill the child―was considered a failure. Tyrell proceeds to activate several war machines to destroy Earth, and hits Superman with a red solar energy beam that pins him down. Tyrell explains the nature of their powers and leaves to make final preparations. Because Superman is the cause of the invasion, no one in Metropolis wants to help. Lois and Jim get Superman out of the energy beam using a truck and Superman regains his strength and stands up. He and Tyrell fight again; this time Superman gains the upper hand by burning Tyrell with his heat vision. Superman's ship becomes fully regenerated, takes off to find him, and knocks Tyrell from behind. Tyrell tells Superman that his own spacecraft is almost as impervious as Kryptonian metal, from which Superman's ship is made. Superman enters Tyrell's weakened spacecraft and destroys it from the inside. Tyrell tries to stop him but is defeated, and he warns Superman that others like him will come to finish the job. Superman jumps off Tyrell's ship. The invasion is over, and Superman smiles and flies away. At a government base, Major Lee wonders who Superman is and what he wants, and whether his presence means more trouble for Earth. The general puts her in charge of researching Superman and his origin, and tells Lee to locate him.

After his ordeal, Clark walks home. The boss of the research company finds him and offers him a job, which Clark declines. A Dheronian battleship crash-lands in an indoor football field. Clark purchases some new clothing and formulates a "Clark Kent disguise". He returns to the Daily Planet, which is more enthusiastic and successful because its coverage of the invasion and Superman was superior to that of rival news media. Perry does not know what to call the new superhero until Clark suggests the name "Superman". Clark is hired because of an interview he claims he conducted with Superman, and he bonds with his new colleagues. Public opinion of Superman is mixed: some like him and see him as a hero; others do not trust him because he was the cause of the invasion. In the Arctic, Superman has hidden his ship in a secret cave, and its sentience activates and tells him his mission: to survive, use his powers well and wisely, and to avenge the murder of his homeworld. At the close of the story, Lois and Jim are on the Daily Planet rooftop discussing how Superman has changed the world. Jim photographs Superman again.

The events depicted in Volume Two occur shortly after those of Volume One. Perry promotes Clark to write articles to help rebuild the Daily Planet's reputation. Lois is suspicious of Clark and the authenticity of his Superman article, so she decides to investigate his past. Clark later meets his neighbors Lisa Lasalle and Eddie Monroe; Lisa and Clark start dating.

Criminal Raymond Maxwell Jensen infiltrates the S.T.A.R. Labs research facility to destroy evidence of his crimes kept by an accomplice. Jensen is discovered by guards and while escaping he is accidentally exposed to a high-energy neutrino that transforms him into an energy-absorbing supervillan called Parasite. Elsewhere, Clark learns that a tsunami is about to hit the island of Borada. He travels there to help as Superman, but the island nation's ruthless dictator General Samsa sees him as a threat and threatens to kill his own people if Superman does not leave; Superman complies. Meanwhile, Parasite feeds on the life force of innocent people, killing them, but is unable to satiate his newfound hunger. Parasite decides that Superman might be powerful enough to feed him.

Distrustful of Superman, Major Lee proposes that the United States should develop countermeasures should he go rogue. Superman is lured to an incident at a power plant where Parasite attacks him and drains his energy, turning Parasite into a hulking beast with Superman's power. Weakened, Superman escapes while Parasite begins a rampage. Parasite's sister Theresa is informed of his actions, but refuses to believe that it is her brother and takes a flight to Metropolis to see for herself.

In the Arctic, the artificial intelligence (AI) aboard the Kryptonian ship that brought Superman to Earth has turned a cave system into a vast Fortress of Solitude. There, Superman researches a means to counter Parasite's power, and the AI offers to build a crystalline shielding warsuit. In the US, Lee responds to Parasite's rampage with military force; during the following attack, Lee realizes that Parasite is progressively weakening as the energy he absorbed fades. Parasite attacks the Daily Planet building to draw out Superman; they fight and Superman is completely drained and powerless, leaving him comparable to humans and capable of being injured. The next day, Superman's powers are restored and he returns to the Fortress. The AI completes the warsuit, but warns Superman that it will prevent him from using his heat vision, will block the sun's energy, which powers Superman, and that if Parasite breaches the suit and absorbs his power again, he will die.

Parasite again attacks the Daily Planet and Superman intervenes. With the warsuit, Superman can fight Parasite on equal terms, but the suit gradually disintegrates as the battle continues. Theresa arrives and Parasite breaks away from the fight to hug her, accidentally absorbing her energy and killing her. Parasite blames Superman for her death and resumes his attack. Superman strikes Parasite with his full strength, incapacitating him. Parasite is taken into the custody of the Secondary Army Advanced Technology Division. During a later telephone conversation with his mother, Clark hears Lisa scream from her apartment and finds she is being attacked. As Superman, he flies her attacker to Alaska and warns him not to go near her again. Lisa tells Clark that she is working part-time as a prostitute to earn extra money. Clark is heartbroken but the pair agrees to remain friends.

In Borada, Superman instigates a rebellion against General Samsa, leading the country to democratic reform. Clark returns to his apartment and learns that Eddie has died of a heroin overdose. He writes an article about Eddie to raise awareness of the dangers of substance abuse. Clark receives a telephone call from a former teacher in Smallville, and learns that Lois is investigating his past. In the epilogue, Lee recruits the wealthy scientists Alexandra "Lex" Luthor and her husband Alexander, to help find a way to kill Superman.

The events depicted in Volume Three occur a week after those of Volume Two. After General Samsa's removal on Borada, the United Nations grows increasingly concerned over Superman. Dr. Alexander Luthor and his wife, Alexandra, play the footage of Superman's battle with Tyrell, revealing that Superman is vulnerable to red solar radiation. In an unspecified desert, an extraterrestrial ship lands. A mysterious humanoid figure appears, and begins to develop powers under Earth's yellow sun. He then tests his powers on a group of soldiers that appear before him, killing them all with ease.

Meanwhile, Clark and Lisa celebrate the latter obtaining a job as a model. Unbeknownst to them, Lisa accidentally drops one of her earrings on Clark's couch. At The Daily Planet, Clark and Jim discuss why Lois is investigating his past. Jim reveals to Clark that Lois is jealous of Clark's Superman story. Lois subsequently warns Superman that she learned from her uncle, a United Nations delegate, that the U.N. is developing fail-safes against Superman. Clark decides to confront Lois over what he found out from his family and friends. She reveals that she has ceased her investigation because she now sees Clark is a decent person of good character, and not the type of individual to fabricate a story.

Lisa has her landlord, Mr. Abrahm, open Clark's apartment door to find her earring. After she retrieves it, she finds Clark's costume in his closet, thus learning that he is Superman. She later tries to imply to Clark what she has learned, but he initially does not understand what she is trying to convey but later. When Superman later goes to the scene of a collapsing bridge, another super-powered being named Zod-El appears, who says he is Superman's biological uncle. Zod claims that he has been searching for Kal-El ever since Krypton exploded. Though Superman is glad that he is not the only survivor of Krypton, he is skeptical of whether Zod is an ally. Elsewhere, Lois discovers melted rods from the bridge and then video footage of an unidentified flying man prior of its collapse.

Zod addresses the United Nations, stating that the House of El caused the planet Krypton to explode, and that Superman is a threat. Zod persuades the delegates that he is an ally and wants to help them kill Superman. Lois receives a phone call from her uncle and learns that Zod is responsible for the bridge's collapse, after which she tries to warn Superman. Zod reveals that he possesses a supply of kryptonite in his ship, from whose radiation his lead-lined skin-suit protects him. He intends to kill Superman, but Superman uses his knowledge of chemistry to cause Zod's suit to disintegrate, forcing Zod to retreat. Superman also discovers that Zod has convinced the world's governments that he is an enemy.

In the Fortress of Solitude, the AI reveals that prior to Krypton's destruction; it was in the middle of a global civil war between Zod and his brother, Superman's father, Jor-El, who had refused to join Zod. Ultimately, forces loyal to the planet's Science Council defeated Zod, and in retaliation, Zod gave the Dheronians the weapon to destroy Krypton. Realizing that Zod intends to complete his revenge by hurting those he cares for, Superman arrives to his apartment building and fights Zod, but is no match for his uncle, who defeats him. Luthor and Lisa intervene to rescue him, but Luthor is killed and Lisa is critically injured. Luthor's red solar weapon greatly weakens Zod, allowing Alexandra to kill him. Blaming Superman for her husband's death, Alexandra vows to kill Superman as she did Zod. She subsequently places her husband's corpse in suspended animation and takes Zod's kryptonite from his ship.

In the hospital, Lisa recovers from her wounds and professes her love for Clark. Clark reciprocates her affection and they become a couple. Clark subsequently takes her to Smallville, where he introduces her to his adoptive mother. At the United Nations, Superman announces that although he is disappointed that they aligned themselves with Zod, it will not deter him from his mission to protect Earth. Seeing their fear, and noting Lois' her astute insights, Superman asks Lois to be his political conscience.

• In the television series Krypton, General Zod (Colin Salmon) is depicted in the series as the uncle of Superman, similar to his version of Earth One.[28]
