The prodigal son of industrialist Lionel Luthor and his wife Lillian, Alexander was always both gifted and cursed by his astounding intelligence. While it was certainly impressive that he was able to read at a high-school level before entering kindergarten, his social development suffered for it. His twin brother Julian regularly beat him up throughout their childhood, a result of feeling threatened by him. The other schoolchildren did the same. His own mother was honestly afraid of him; while she would comfort him and tell him he was 'special,' every day in the back of her mind, there was a growing dread that her boy was becoming something terrible. Lex's father, on the other hand, was all too eager to feed the boy's ever-accelerating mental development, never bothering to look at his son's present but rather his future. In Lex, Lionel saw greatness.
And so the family would pack up and move across the globe, wowing the heads of prestigious institutes, becoming the toast of the world's leading techno-centric hubs, doing everything they could to keep Lex on the fast track to success. Julian suffered for it, never getting to have any friends before having to move again, never getting out from under his brother's shadow, never having an identity or life of his own. At age sixteen, Julian hanged himself, and his death was the first time since infancy that Lex felt genuine emotion.
Seeing the need to move to a more wholesome atmosphere for a while, the Luthors decided to finish Lex's education in a small, friendly rural community in Kansas called Smallville. Lex even enrolled in a public school for the first time, begging his parents to give him the chance to live like a regular teenager. Still used to flaunting his brain-power and being treated like a celebrity in the science community, he came off to most as arrogant and condescending, which only alienated him even more. The only person he could really relate to on any personal level was a particularly gifted farm boy by the name of Clark Kent, although Lex never really considered himself a friend--frankly, he never learned how to make friends, or saw the need for them at all. Everyone else shunned him quietly, and he in turn despised them openly. While it was meant to brighten up his life after his brother's death, Lex's time in Smallville only made his thoughts and feelings darker.
While in Kansas, he did find one thing that kept him intellectually stimulated: a sample of unbelievably rare extraterrestrial mineral that had landed there as part of a freak meteor shower some years prior. Absolutely fascinated by the incredible amounts of energy given off by the rock--and its remarkably clean radiation--he set to work on testing its potential applications.
Tragically, his experiments the rock would lead to disaster, as an overloaded circuit would eventually cause an explosion that utterly destroyed the Luthors' home. He suffered second- and third-degree burns on over half of his body, disfiguring him completely. His mother and father did not survive the blast at all. With all of his family dead and his research ruined, Lex had no reason to remain in Smallville, and would practically disappear for almost five years.
At the age of twenty-three, Lex Luthor unexpectedly re-appeared on the Metropolis scene. Having undergone several rounds of extensive plastic surgery, his burn scars were completely gone--along with his hair and eyebrows, unfortunately.
Far more remarkable, however, was the transformation of his personality. Gone was the introverted, demeaning, almost misanthropic walking-brain that had driven so many people away. Now, Lex was a smooth talker, a wild playboy, a shrewd businessman, and a natural showman, all without losing a shred of his staggering brilliance. People from all walks of life began to gravitate toward him, practically worship him, and within a year of his taking the helm, he Lex had taken the floundering LuthorCorp (now re-christened as LexCorp) and made it one of the most profitable companies in America. After another year, it was the most profitable company in the world. Tens of thousands of patents flowed from the newly-constructed LexCorp Tower in Metropolis, ranging from city-spanning energy shields and self-sustaining space stations, to a more efficient toaster.
What made many uneasy, however, was the intricate web of connections Lex began weaving with a myriad of organizations. Private military contractors, 'community outreach' programs in cities across America, major media outlets, banks and financial firms, all churning out praise for Luthor and his new movement simply known as "Society." Several Senators and Representatives began passing suspicious bills that seemed only to benefit LexCorp or its many, many subsidiaries. Critics began either drastically changing their tone or suddenly finding themselves out of work. While there were many who had doubts about Luthor's plan for America, there were few who could truly oppose him.
Until Superman arrived.
Bursting onto the scene with all the pomp and pageantry of a mythological god, Superman began breaking people's devotion away from Luthor, and little by little, began exposing Luthor's true motives. While there were still many in the country who would believe anything Lex said, Superman's mere presence and defiance began sprouting a grassroots campaign against the Society, spurred on by the infuriatingly popular Daily Planet. What began as simply a freakish do-gooder became a massive stumbling-block for Lex's designs.
Three years later, Lex Luthor is growing more powerful than ever, but has to fight tooth-and-nail for every bit he gets. He has devoted almost all of his attention to discrediting and destroying the alien, and while he maintains his cool and suave demeanor on the outside, his repeated failures to oust Superman are turning him into a fanatical maniac on the inside. He is raising an army to do his bidding, and has unthinkable weapons at his disposal. Lex Luthor believes the only solution is all-out war on Superman. And in his mind, the spoils are the very future of the human race itself.
