Doctor Polaris (John Nichol)

Doctor Polaris is an alias used by two supervillain appearing in American comic book published by DC Comics. The first and most prominent is Neal Emerson, a scientist who can manipulate magnetism.

Created by John Broome and Gil Kane, the first Doctor Polaris, Neal Emerson, made his first appearance in Green Lantern #21 (August 1963).

The second Doctor Polaris, John Nichol, first appeared off-panel in Justice League of America vol. 2 #11 (September 2007), before receiving a full introduction in Justice League of America vol. 2 #17 (March 2008). Nichol's origins in this issue were developed by Lilah Sturges and Andre Coelho.

Neal Emerson and his brother John were raised by an abusive father (although a later flashback shows him raised by an abusive aunt). This apparently drove Neal Emerson within himself and led to the creation of the personification of his own dark side. Emerson left the United States for a year and returned to find he was an uncle. His brother John and sister-in-law Katherine had adopted a baby and named him Grant. Emerson is not around much for his nephew over the years, but is fond of him.
