Calvin Zabo (Earth-7045)

Dr. Calvin Zabo is a morally abject but brilliant medical researcher who was fascinated by the effect of hormones on human physiology. He was also a colleague of Dr. Donald Blake. One of his favourite stories was R.L. Stevenson's 1886 classic, Dr. Jekyll and Mr. Hyde, from which he would name his supervillain identity after.

Powers

 * Hyde Formula-Induced Transformation:
 * Superhuman Strength
 * Superhuman Stamina
 * Superhuman Durability
 * Healing Factor

Abilities

 * Genius-Level Intelligence: Calvin Zabo is a gifted scientist and chemist. However, when transformed into Hyde, his intelligence decreases to within normal human ranges.
 * Hand-to-Hand Combat

Weaknesses

 * Zabo originally had to ingest his formula on a regular basis in order to remain as Hyde, otherwise he would revert to his normal state after a certain amount of time. This is not 100% consistent, however, due to constant changes to the formula and Zabo's own bio-structure. At times he can trigger the change at will without using his formula, or has remained as Hyde indefinitely without reverting back or reapplying his formula.
 * In his Hyde form, Zabo is also prone to savage, almost bestial rages in which he becomes reckless.
