Dr. Calvin Zabo was a morally abject but brilliant medical researcher who was fascinated by the effect of hormones on human physiology. One of his favorite stories was R.L. Stevenson's 1886 classic, Dr. Jekyll and Mr. Hyde. He was convinced that the experiment in the story could actually be performed and obsessed with the idea of unleashing his full bestial nature in a superhuman form. However, he needed money to do this so he robbed his various employers systematically. Though too intelligent to be caught, the medical community was suspicious of his tendency to always be employed by organizations which were subsequently robbed.
He sought work as a surgeon in a hospital where Donald Blake was a directing physician, yet Blake would not allow him a job due to his history. Zabo was enraged that Blake would not give him the position, even though he did indeed intend to rob the organization. He swore revenge on Blake. He was eventually successful in creating his formula, and turned into a huge, creature he called "Mister Hyde", named after the Mr. Hyde in the book. In this new form he found he had vast superhuman strength enabling him to crush cars and tear through steel as though it were made of cardboard. With his new superhuman powers he sought out Blake and beat him senseless. He next kidnapped Donald Blake and Jane Foster and even though he was once again defeated, he managed to escape, fearing that if Hyde was captured, Blake would be killed by a time bomb Hyde had set.
