Bio: Dr. Henry Jekyll is allied with Vampire in preventing Warlock from subjugating humanity. He is charged with finding a scientific means to undo Warlock's miniaturization spell. He consistently carries his Hyde potion with him, and when he becomes Mr. Hyde, usually upon force-feeding, he is unpredictable and cannot be relied upon by either side.
