Doctor Polaris is the master of magnetism. Mentally disturbed scientist Neal Emerson gained incredible powers by exposing himself repeatedly to intense magnetic fields, and developed a criminal persona. These abilities make him one of the greatest enemies of Green Lantern. He has also been a member of the Secret Society of Super-Villains and Cadre. During Infinite Crisis he was killed by Human Bomb. His post-mortem successor is John Nichol, originally a businessman inspired by the original. Nichol was also a prominent member of the criminal organization Intergang. He was killed during the Blackest Night by the Black Lantern Neal Emerson. His Prime Earth counterpart also became a member of the Suicide Squad.
Doctor Polaris was created by John Broome and Gil Kane, first appearing in Green Lantern (Volume 2) #21 (1963).
