Jules was the father of Lex and Lena Luthor.

After Lex turned to crime, Jules Luthor disowned the boy and changed the family name to "Thorul". Both Jules and his spouse were eventually killed in a true tragic car accident, and their daughter was raised in an orphanage.

  • This version of Lex Luthor's father, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
