If they have superpowers, chances are they’ll be here for one of the country’s premier comic book conventions, among the few to largely eschew other aspects of popular culture in favor of celebrating the glory of panel-by-panel storytelling. There’ll be cosplay, there’ll be dealers aplenty, there’ll be panel discussions, workshops and Q&As, and there’ll be a bevy of comic artists and writers on hand to sign their work. And if you want to show up dressed as Spider-Man or Wonder Woman, all the better. 1 p.m.-7 p.m. Sept. 28, 10 a.m.-7 p.m. Sept. 29, 10 a.m.-5 p.m. Sept. 30 at the Baltimore Convention Center, 1 W. Pratt St. $25-$165. baltimorecomiccon.com.
