Personality
Lucas is a sociopath willing to do just what it takes to become wealthy and save himself with no remorse or conscience just like his half brother Lex Luthor (when Lex was a teenager, he was awfully a nice guy and a good friend to Clark Kent who would one day grow up to Superman and be his enemy).Lucas intentionally elbowed Clark in the jaw to injure him just so he could win a basketball game and fired Lana Lang from the Talon to get back at Clark for gathering information of him. When Lucas kidnapped Lex, he knocked Jonathan Kent out which was not part of Lex's plan. Lucas was also willing to betray Lex and Lionel for wealth from LuthorCorp, however Lex decided to take care of Lucas since he wanted family intimacy and protected him in the end from Lionel.

Biography
Lionel forced his girlfriend Rachel Dunleavy to give Lucas up for adoption and lied to his son Lex that Lucas died. Lionel located Lucas when he was twelve and provided anonymous financial support him. Lucas was never really adopted and grew up in poverty in a lot of foster homes.

In 2003, Lex found Lucas in Edge City after a seven month search and saved from some gangsters who were after Lucas since Lucas cheated them at a poker game. Lex took Lucas to Luthor Corp to meet Lionel and organize a takeover of the company. Lucas betrayed Lex when Lionel gave him ten million dollars to sign his share away. Lionel and Lucas took Lex's share of the inheritance and threw him out of the mansion.

Lucas realized that at his age, he can have a more sizable inheritance than what Lionel was offering and had angry feelings since Lionel abandoned him. Lucas even realized that Lionel was never blind. Lucas also took control of all of Lex's assets which included the Talon and tried to fire Lana Lang just to get back at Clark for collecting information about him.

Clark saved Lucas when one of the gangsters located Lucas. Lex discovered that Lionel tipped the gangsters off on Lucas' whereabouts and revealed that to his half brother. Lucas kidnapped Lex and Clark followed Lionel to rescue him.

Lucas swore to kill Lionel unless Lionel killed Lex. Clark used his heat vision to make Lionel shoot Lucas instead, however Lionel's gun was filled with blanks. The two half brothers then revealed to Lionel they schemed together to prove Lionel was no longer blind and worked together to make Lex run LuthorCorp again.

Lex sent Lucas to a place where he would be protected.
