Final Crisis

In Justice League of America (vol. 2) #21, Lex can be seen associating with Libra's Secret Society of Super Villains and placed in its Inner Circle. Lex wanted Libra to prove himself, so Libra sends Clayface to blow up the Daily Planet building. As Lex attempts to ambush Libra after learning that he is a prophet of Darkseid, Lex soon ends up surrounded by Justifiers. Libra tells Lex to make a final choice... swear an oath to Darkseid or become a mindless slave. In Final Crisis #5, Lex is seen when Libra blames Calculator for cracking the computer codes that will help the resistance. Lex is silent on the matter, but has been picked to lead the rearguard action against the heroes at Blüdhaven. He assumes it's an honor, but he doesn't look very pleased. During Final Crisis #6, Libra figures out Lex had been the mole in the Society of Supervillains. Lex, in league with Doctor Sivana, seemingly destroys Libra and overturns the Anti-Life Equation being broadcast into the Justifiers' helmets.
