Batman: The Brave and the Bold

In Batman: The Brave and the Bold TV series, Lex appears in the episode "The Super-Batman of Planet X" portrayed by Clancy Brown. He appears as the Lex Luthor of Zur-En-Arrh and possible the arch enemy of the Batman of that world. Both Batmen ended up fighting Lex and his army of giant robots (resembling the ones from the comics) when Batman discovered that he had superpowers upon being exposed to Rodon. He used his new abilities to defeat Lex's robots and apprehend Lex. While in jail, Lex discovers Earth Batman's weakness and plans to use it against him as Rodon-powered Earthlings are weak against Quartz (in other words, Rodon and Quartz don't mix). Lex contacts one of his robots which springs him out of jail while quoting to the guard that he's "done with the room." When Batman confronts Lex, he has one of his robots open a compartment that contains Quartz. Batman of Zur-En-Arrh rescues Batman and sprays him with something that protects him from the Rodon's events. When Lex tries to take Vilsi Veylar hostage, he ends up defeated by both Batmen.

Lex appears in Batman: The Brave and the Bold issue #1 where he controls a composite monster that attacks Batman and Power Girl in England
