Lex Luthor is a supervillain in The CW's Arrowverse, based on the character of the same name created by Jerry Siegel and Joe Shuster. Adapted for television in 2017 by Glen Winter and Greg Berlanti, he made his first appearance in the Supergirl episode "Luthors". Both Aidan Fink and Jon Cryer portrayed versions of the supervillain, with Aidan Fink portraying a young Lex Luthor and Jon Cryer portraying Lex as an adult.
In the Arrowverse, Luthor is an independent businessman who runs a company called LuthorCorp, and is also the arch-nemesis of Superman. Formerly, Luthor and Superman were friends; their friendship ended when Superman refused to embrace Luthor's violent and chaotic ideology. Luthor then developed an obsession with Superman, resulting in his eventual imprisonment. Later, he perceives Supergirl as a threat and shifts his focus towards her.
