Cornello is a lowrate alchemist and a fraud. He uses what he thinks is the Philosopher039s Stone to fool the people of Lior into thinking that he is sent by the Sun God Leto with the power to perform miracles including resurrecting the dead. Although he uses alchemy to bring prosperity to the desert city his true intention is to convert the citizens into a fanatical army. The Elric brothers expose him for a fraud and shortly afterward the incomplete Philosopher039s Stone becomes unstable and shatters as it tears his arm into a mass of flesh and metal. After the Elrics undermine his plan and Cornello is no longer of any use to the Homunculi he is consumed by Gluttony. Envy disguised as Cornello maintains the deception until Lior is subjugated by the State Military. In the manga Lust tells Gluttony he039d be better off not eating a fourthrate fraud like Cornello and kills him herself. Gluttony eats Cornello039s dead body afterwards Lust replying to Gluttony rather annoyed quotI thought I told you not to eat thatquot.
