Early LifeAlexander was neglected by Lionel in favor of his "superior" brother. Lex's mother Lillian nurtured her son and stepdaughter, encouraging their curious minds and education. Lionel didn't understand nor appreciate his son's brilliance, something that would come to haunt him later in his life.
When Clark was very young, he threw a tantrum that in the process killed Lillian. Lionel swept it under the rug while Lex was in shock and formed a life long resentment for his brother.
Escaping the Luthor Curse
Lex went on to complete college at age 12, and formed his own company separate from his father on his 17th birthday. He met a girl from Smallville and they fell in love, resulting in the birth of Alexander Luthor Jr.When Lionel and Clark were preparing to overthrow the government, Lex spread the word and started a resistance. To make an example, Clark killed Lex's wife in front of Lex and his son, leading Lex to dedicate himself to bringing his brother down.
Lex formed an inner circle of resistance fighters with their own special abilities, and began experimenting with kryptonite to find his brother's weakness.
When Clark and Lionel disappeared, Lex partnered up with Oliver Queen and pooled their resources to supply the world with kryptonite to protect themselves from Ultraman.
When Clark discovered what his brother was up to, he confronted him planning to kill him. What he didn't know was that Lex knew he would kill him and created a clone to fake his death and hopefully rob his brother of his powers.
When Ultraman returned seemingly reformed, he knew it was good to be true. To that end, when the world rejected Clark due to his past actions, Lex was not surprised when Clark returned to evil, and in a fit of rage wiped out all of Metropolis and all of Lex's allies. When Ultraman seized absolute control, Alexander left to our world to find our Clark and get his help to free his world.
