"imprisoned under the nom-de-crime of Doctor Destiny"

John Dee, or Doctor Destiny, made his first appearance in 1961 as one of Green Lantern's enemies, and went on to battle the Justice League of America multiple times. He is named after a noted occultist and consultant to Queen Elizabeth I, but does not seem to be intended to be the historical figure himself. His mother Ethel Dee, formerly Ethel Cripps, is Gaiman's creation.
