Hunter Zolomon (died May 24, 2017) was a meta-human speedster from Earth-2. Years after witnessing his father murder his mother when he was a child, Hunter became a serial killer. Following the S.T.A.R. Labs particle accelerator explosion, Hunter was affected during electroshock therapy by the dark matter emitted, giving him superhuman speed and various other abilities derived from it. Following this, he escaped and began acting as the supervillain known as Zoom, stylized as the Speed Demon.
