Here’s Neverending Dreamz with the best damn Lucio cosplay you’ve ever seen (or heard).
That music you hear in the video below isn’t coming from the con; it’s coming from the gun, which is an 8-inch subwoofer with two 4-inch speakers on either side. It plays music from his phone, and both the gun and lighting (which is synced to the beat) are powered by a battery he carries around.
