Hugo Arnold (Professor)

A scientist with an "over-inflated ego" who, bitter at having been overlooked by the Gotham City Historical Society in con­nection with its plans to stage a series of historical pageants honoring famed ancestors of Gotham City celebrities, resolves to "smash the Historical Society's pageants" and then "astound the world with a scientific wonder-·so that no one will ever ignore me again!" After using an ingenious "brain-stimulator" of his own invention to send "tremendous power surging through [his] brain" - thereby transforming himself into a scientific wizard of unparalleled genius while at the same time endowing himself with a cranium of "freakish size to accommodate the huge size of [his] brain" – Professor Arnold uses his astounding intellec­tual capabilities to create an arsenal of mind-boggling inventions, including a deadly "lightning cannon" and invisible flying robots, to enable him to disrupt the historical pageants and then cap his revenge with the scientific feat of creating a second moon for Earth, regardless of the fact that by colliding with the existing moon the new moon could literally cause the destruction of Earth. Professor Arnold and his henchmen are apprehended by Batman and Robin in August 1962.
