Envy is the fourth homunculus that father made. He has the ability of shape-shifting, meaning that he can assume the form of any person or persona that Envy creates (Envy has become a dog as well as a dragon). He can even modify his own voice to copy others. Envy is most comfortable in his "beautiful" form as an teenager. He is usually used as a spy, but his abilities are also extremely useful for assassinations, as demonstrated in the murder of Maes Mughes. Envy most frequently assassinates people by imitating the target's loved ones or close friends, using their hesitation as a window to kill them.
