Lex Luthor has long been the most dangerous human threat to Superman and his squad of heroes. In fact, other than The Joker, Luthor is the most iconic villain on the DC Comics roster. The skilled tactician, businessman, and politician proves that having abilities isn't the only way to become powerful. Luthor has built suits that mimic power, has amassed countless criminal and political friendships, and is worth almost as much as Bruce Wayne. His cunning is more lethal than most heroes' strength. According to a report from DeadlineLuthor will be heading to the new season of Supergirl. 

“We’re beyond excited to introduce iconic villain, Lex Luthor, to Supergirl and to weave him into our story this season,” executive producers Robert Rovner and Jessica Queller announced in a joint statement. “We’ve talked about having Lex on the show since it’s inception and we’re excited to have him finally arrive. We can’t wait for him to shake things up in National City and watch him go toe-to-toe with not only Supergirl, but his sister, Lena Luthor.”

The villain has yet to be cast, but The CW plans on filling Luthor's shoes as soon as possible. Supergirl kicked off its fourth season last weekend.
