Every homunculus was once originally a failed human transmutation. What they retain of their once human selves is debatable. Envy has battled his demons for 300 years and is still haunted by the details of his former life; the life of Wilhelm, son on Dante and Hoenheim. This is the story of how the once praised alchemist became the embodiment of jealousy. (Based off the 2003 anime storyline)
