It's a comic book battle that even the Avengers couldn't handle. Tonight, four comic book artists and their stand-up comedian sidekicks will duke it out for sketchpad supremacy inside Manhattan Beach shop/hangout the Comic Bug. Presented by Comics and Comics, a group of comedians who perform geek-friendly stand-up at conventions across Southern California, Sketch Fighter is a test of skill and speed. With 60 seconds on the clock, teams will vie to be the fastest, funniest sketch artists in the comic book shop. After the game, an auction for drawing pads features both work from the competition and one other drawing from each artist. Proceeds from the auction will benefit Hero Initiative, a nonprofit that provides financial assistance for comic book creators. The Comic Bug, 1807 Manhattan Beach Blvd., Manhattan Beach; Sat., Aug. 2, 8 p.m.; no cover. (310) 372-6704, thecomicbug.com.
