20 TV Characters Who Died In 2019
13. Lex Luthor - Supergirl
It's safe to say we're all familiar with Lex Luthor by now. The billionaire industrialist, scientist and all-round megalomaniac has been Superman's arch-nemesis since his first appearance in Action Comics way back in 1940, and is likely the most famous villain in all of superhero fiction.
After a huge arc trying to kill a weakened Superman which also involved framing Supergirl for an attack on The White House, harvesting DNA from alien prisoners, creating an evil Supergirl clone and generally just being a massive pain in the arse, he finally gets his comeuppance.
Shot by his sister Lena, Lex uses his final moments to reveal Supergirl's true identity as Kara Danvers, leaving the series on a massive cliffhanger. It is, however, entirely possible that Luthor will be resurrected in the lead-up to the Arrowverse's Crisis On Infinite Earths crossover event, scheduled for imminent release.
