There Is No Justice League
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 was not around much for his nephew over the years, but he was quite fond of the boy.
As a medical student, Neal Emerson develops a fanatical interest in magnets, despite the teasings of his classmates. Emerson is convinced exposure to magnetic fields will give him more energy. He later holds crowd-drawing lectures on “Health via Magnetism.” Due to his medical background and belief in magnetism, Emerson adopts the name “Doctor Polaris.” He even designs a special costume and mask to wear for his public appearances.
