Sex Bob-Omb is a fictional band from the film Scott Pilgrim vs. the World, based off the comic book series by Bryan Lee O'Malley. The band consists of lead singer Stephen Stills (Mark Webber), bass player/titular character Scott Pilgrim (Michael Cera), and drummer Kim Pine (Allison Pill).

It’s interesting to note that the band’s name draws from an enemy in the Mario franchise, adding onto the series' notorious video game themes and references. All Sex Bob-Omb songs were written by Beck Hansen.
