Hotspur is a piece of computer software, programmed with the complete works of William Shakespeare, that became sentient and insane, overloaded by the beauty and strong emotions in the Bard's work. Inhabiting the body of a giant insect-like robot, it stole an alien artifact from Dr. Fay, intending to use it to bring about the end of the human race. Hotspur was apprehended by Martin Rock (the second Green Knight) and Derek Mason, the Blue Boxer. Though his plan was thwarted, the activated artifact did lead to the creation of the Little League of Doom.
Hotspur only spoke in Shakespearean quotations.
