Germ is Germ. His name is actually Jeremy Warton, but Germ Warfare just stuck. In fact, no one knows where Germ lives, what Germ does, or what his deal is (apart from Mae). At some point, he started showing up to hang out. Sometimes he comes to listen to the band, which consists of the main characters. He’s nice enough, but who knows? He’s weird. He’s Germ.
