Alexander Joseph "Lex" Luthor was the founder of LexCorp and an important businessman and Superman's archenemy. Following Darkseid's invasion, fearing what Superman could make to the Earth, he founded the Legion of Doom in order to defeat the Justice League and pursue his own criminal operations.
Justice League: The Flashpoint Paradox
Luthor was part of Deathstroke's Pirate crew at the time, however his scene was cut short after Aquaman and his armies stormed Deathstroke's ship, killing Luthor and Deathstroke onborad.

Justice League vs. Teen Titans
The Death of Superman
Lex Luthor was put under house arrest for his activities. He was later visited by an annoyed Superman who accused him of planning attacks on Mayor Booker through the Intergang armed with Apokoliptan technology, which Luthor subtly denied. Before leaving, Superman tells Luthor, "This city's never going to love you just for hating me", a comment which seriously vexed Lex.
After most of the Justice League have been beaten, Lex Luthor appears and battles Doomsday, blasting him with a powerful energy cannon across the city, and is the first hit to even scratch him. However, when he attempted to get a sample, he was swiftly overpowered and his battle suit was torn apart. Superman recovered just in time to save him.

To be added
Luthor is visited by Batman asking for information on a delivery list of an ethylene compound to track down Poison Ivy's location. Luthor provided him with the location and demanded to be treated with respect, since he was a Justice League member now. Batman reminded him that he was only a probationary member, much to Luthor's ire.
Justice League DARK: Apokolips War
Now a member of the Justice League, Lex Luthor, along with the other members, attends the Justice League's briefing of their planned attack on Darkseid and Apokolips. Luthor audibly expresses his disagreement with Superman's plan, opting to negotiate rather than fight, but Superman shoots down his proposal of sending an envoy to Apokolips. Luthor agrees to stay in his place as Superman refuses to take the chance that Darkseid will cooperate forever, and they must get rid of him. Later, Luthor accompanies the Justice League as they invade Apokolips. Upon arrival, they are attacked by Paradooms, genetic hybrids of Parademons and Doomsday. Despite the League's efforts, they are utterly decimated, with the League's members either killed or captured. It is unknown how Lex Luthor escaped without injuries, but it is likely he surrendered.
Two years later, after Darkseid assumed tyranny over Earth after the defeat of the Justice League and the Teen Titans, Lex Luthor reclaimed his position as the top of LexCorp as he acts as a New God representative between Earth and Apokolips, while secretly relaying intel to Lois Lane in favor of her resistance force but keeping himself anonymous. Luthor serves as an act of communication to Earth by Batman, who has been brainwashed to become Darkseid's right-hand man. Given that LexCorp is home to Earth's one and only boom tube, which is the only means of traveling to and from Apokolips, Batman gave Luthor orders to transport the Paradooms to Earth after being alerted of the resistance force's attacks on the Reapers.
When the resistance force invade LexCorp to use the boom tube, they are confronted by Luthor in his battle suit. After Luthor hurts Damian, Raven momentarily loses control of herself and a portion of Trigon emerges, which destroys Luthor's suit and would have killed him if Raven did not regain her control. Luthor reveals to the group that he is Lois Lane's anonymous source, acting as a double agent. Luthor joins the resistance force, giving the depowered Superman his battle suit equipped with Kryptonite-laced weapons (which is ironic considering it was created to kill Superman), and the other fighters their own Kryptonite-laced weapons to combat the Paradooms. Using the boom tube to transport Superman, John Constantine, Raven, Damian Wayne, and Etrigan to Apokolips, Luthor is contacted by Batman who becomes aware of Luthor's betrayal, which puts an end to Luthor's double agency.
Luthor stays behind with Lois Lane and the Suicide Squad to combat the Paradooms, intent on keeping them away from the boom tube and thus Apokolips. The group do well at first to fend them off, but become vastly outnumbered, and Luthor erects a Kryptonite barrier to buy time for him to set the self-destruct sequence of LexCorp. Soon after, Luthor's corpse is seen, having been butchered by a Paradoom.
