Lex Luthor

"Metropolis and her people are mine -- and they'll live or die as I see fit!"

- Lex Luthor

"One day, very soon now, you're going to die, Superman. You're going to be destroyed. And you'll know who's doing it. Everyone in Metropolis will know. But no one will ever be able to prove it.

- Lex Luthor to Superman.

He serves as the main antagonist of the Superman comic series, alongside Brainiac and General Zod and the archenemy of Superman. Luthor is also a major antagonist in the Justice League series being the leader of many supervillain groups, most notably, the Legion of Doom.

He is a genius billionaire and the owner of LexCorp, who possesses an undying hatred of his archenemy, Superman. He will stop at nothing to kill his archenemy, and then rule Metropolis and the world.

He was created by Jerry Siegel and Joe Shuster in 1940.

Personality
Lex Luthor is an extremely intelligent, calculating, duplicitous and unpredictable man of immeasurable ruthlessness. He was a mechanical, strategic and scientific genius, maintaining a series of accomplishments in his life. However, due to his intelligence, he is extremely arrogant and narcissistic.

He has an incessant habit of flaunting his own intelligence, referring to himself in the third person and creating monuments to himself. He also believes himself to be the greatest criminal mind of his time. As such, he is a complete megalomaniac. He seeks to control everything he sees due to a delusional sense of entitlement.

With no sense of empathy, he cares nothing for his fellow man and only keeps people alive if they benefit him. Lex is completely obsessed with destroying Superman because the latter threatens his power and sense of supremacy. This leads to him referring to the Man of Steel in diabolical terms, indicating an obsessive hatred of the Kryptonian.

New 52
Lex Luthor's history and origin was altered during the New 52. In this continuity, Alexander "Lex" Luthor was born and raised in Smallville with his sickly sister Lena before moving to Metropolis where he got into contact with the extraterrestrial villain Brainiac.

As the pair secretly traded information between one another, Lex was recruited into an alliance with General Samuel Lane and Glen Glenmorgan to bring down Superman. But Luthor instead betrayed them by stealing their Kryptonite and having the plot leaked to Daily Planet reporter Clark Kent.

Eventually, Brainiac found his way to Earth and Lex tried to aid the invader in shrinking Metropolis. However he was caught and accused with endangering the city. During this time, Glenmorgan was also facing criminal charges, and his mind snapped under the pressure.

Meanwhile, Lex was let go due to lack of evidence and decided to fill the power vacuum left by Glen, who was Metropolis' corporate master at the time. Fours years after the foundation of the Justice League, Lex Luthor masterminded an invasion in order to sell superweapons to the army. It was this crime that had him come to blows against Superman for the first time. The ensuing fight between them resulted in Luthor receiving a scar across the left side of his face, his defeat, and his imprisonment for a year.

Lois and Clark: The New Adventures of Superman
In the TV show Lois and Clark: The New Adventures of Superman, Lex is a criminal tycoon posing as a legitimate businessman. His main goals were to have Daily Planet reporter Lois Lane for his own and destroy Superman and would go to extreme dangerous lengths to do it.

Smallville
In the TV show Smallville, young Lex Luthor (played by Michael Rosenbaum) became best friends with Clark after the farm boy saved his life during a car accident. Nevertheless, he envied Clark's happy family life, as he had a dysfunctional relationship with his abusive father, Lionel.

Their relationship crumbled, and Lex was set on the road to evil. He would use and abuse people with meteor powers, just as his dad would do, until one day he decided to murder his father. He later found out Clark's secret, and was seemingly killed in the Fortress of Solitude's explosion. He was revealed to be alive but severely injured.

He had to rely on life support through tubes and breathing machines and his face was partially scarred and wore a kryptonite ring with an L insignia. He used Winslow Schott to assist him in his revenge. Wanting revenge, Lex killed all of his previous staff when he attempted to murder Oliver. Watching a view screen connected from Schott's puppet eye, he monitored Schott's setup of a meteor-rock bomb on the roof of the Daily Planet. Knowing Lana had stolen his Prometheus suit, he set Clark and Lana up so that she would have to absorb the meteor rock to diffuse the bomb, and as a result, never be able to go near Clark again.

Just when Clark was about to confront Lex, a toy bomb of Schott's that Oliver put there caused a nasty truck explosion with Lex inside, killing him. Lex's remains from the charred truck were later scattered by Clark. Sometime later, Lex was hallucinated in Oliver's reflection. Lex was mentioned by Doctor Fate as Clark's ultimate opponent in the future, but assured him that he would one day finally triumph over Lex. Clark questioned this, believing Lex had been killed to which Doctor Fate did not respond.

While in a spiritual cornfield, Lex was seen amongst the stalks of corn by Clark. He then disappeared while Clark returned to life. Afterwards, it was discovered Lex used Cadmus Labs to create many clones of himself with the intent to use the clones' body parts to heal his own injuries.

Unknown to anyone for some time, Lex took his failed clones' best pieces to create a perfected, composite clone LX-Ø. Unfortunately, he was unable to successfully duplicate a heart at the time. After Lex's "masterwork" is discovered by a Lionel Luthor of an alternate reality, Lionel's biomedical research company tried to locate Conner Kent for a heart to give LX-Ø but Tess' efforts to hide Conner forced Lionel decide to use Tess as a last resort.

While Apokolips was approaching the Earth and after Tess escaped and shot Lionel for planning on using her heart to revitalize Lex, Lionel desperately crawled toward Lex to which Lionel and Darkseid made an exchange: Darkseid would give Lionel's heart to Lex while Lionel surrendered his own soul to Darkseid in the process. Completely restored, Lex noticed the alternate-Lionel's change of heart and met with Clark at the Luthor Mansion's remains. Lex told Clark that he embraced his destiny as Clark's nemesis. He was then able to encourage Clark to go fight Darkseid, saying that Clark couldn't defeat Darkseid but they both knew who could.

Lex later arrived at LuthorCorp and confronted Tess, revealing he knew that she was his sister all along and the fact that she shot the alternate-Lionel (who only wanted Lex back). He told her he loved her and the two siblings embraced. Subsequently, Lex stabbed Tess with a long blade. As Tess died, Lex said he was saving her from becoming him, to which she said Clark already has. Tess then rubbed Summerholt's neurotoxin on his face, which interfered with his memory. She told him he had 30 seconds until his memories were wiped. He forgot everything that happened throughout his life in Smallville. Lex looked out of the office window at the coming Apokolips while its chaotic damage "destroyed" LuthorCorp, leaving behind LexCorp in its place.

Lex Luthor later fought the Justice League, where he was subsequently defeated. It was then he was exposed as a crook and taken into prison. Graves took over LexCorp affiliations in his absence. He paired up with other villains in an attempt take down the Justice League.

Lex Luthor redeemed himself in aiding in the defeat of the Justice Lords and was given full pardon. However, still bent on destroying Superman, Lex created project Cadmus and succeeded in ruining the Justice League's reputation twice: once by causing Superman and Captain Marvel fight each other and again by having the Watchtower fire at a Project Cadmus related building in New Mexico. After being exposed for his malevolent plans by Batman, Brainiac revealed he had been dormant inside Lex Luthor for some time. Lex Luthor convinced Brainiac to fuse with him because both would reach their ultimate goals, he served as one of the Justice League most difficult foes. However, Flash was able to separate the two after breaking the speed force. Lex went back to jail with a damaged psyche.

After escaping prison again and eluding the cops, Gorilla Grodd offered Lex to become a major player for the newly formed Legion of Doom. Joining only to revive Brainiac (after growing an obsession with him), Lex eventually overthrew Grodd and set the course of the mission toward Apokolips. There he found a version of Brainiac that had been destroyed years earlier. Trapping and absorbing Tala's magic to resurrect Brainiac, to his surprise, he had accidentally recovered Darkseid instead. Warning the Justice League due to him wanting to kill Superman first, he joined them to fight against Darkseid. Lex Luthor later left the battle by Metron and discovered the Anti-Life Equation.
