Today's lineup of Arrowverse panels at Comic-Con continued with a very eventful Supergirl panel. Among other things, we learned that the show's upcoming fifth season will feature plenty more Luthor family villainy in the lead-up to Crisis on Infinite Earths. First of all, check out an IGN-exclusive look at the Season 5 sizzle reel, which showcases a villainous turn for Lena Luthor, the rise of terrorist organization Leviathan and a storyline geared heavily towards society's growing disconnection and obsession with electronic devices. In a big reveal, actor Jon Cryer (who also moderated the panel) revealed he'll be reprising the role of Lex Luthor during the Crisis on Infinite Earths crossover in December.
