Dr. Droid, also known as Edward Droid is the nemesis of The Knight.
Dr. Edward Droid was born in the 1940's and became a scientist. He later found out he had cancer and attempted to, with the help of some other scientists, transfer his brain into a robotic body so he would not die. The robotic body, however, altered his mind, and turned him into a psychotic murderer. Because of that, he and The Knight became enemies.
