By consuming different mixtures of his transformation potion, Calvin Zabo can transform back and forth from his alter-ego of Mister Hyde. The chemical process is hormonal in nature, causing the cells of his anatomy to instantly manufacture mutated hormones that induce a physical transformation encompassing his entire figure. Miraculously, over 200 pounds of bone and muscle tissue are added to Zabo's body. After about 30 seconds of excrutiating pain, the entire metamorphosis is complete. Hyde and Zabo have different finger prints, while Hyde's facial structure is distorted to the point that he is frozen in a perpetual sneer. Zabo's personality is also distorted. As Hyde, he is overcome with savage anger and bestial ferocity. His body’s dense flesh provides some degree of protection and he possesses vast superhuman strength and stamina.
