Lujon

Lujon is a character exclusive to the 2003 anime series. First introduced as a struggling young doctor in his small town studying medicinal alchemy in the hopes to cure a local plague called the "Fossil Disease". He was eventually discovered by Lust and given a fake Philosopher's Stone, along with teaching him more advanced forms of alchemy. However, after the Homunculus leaves his side, the stone slowly begins to fade, and he flees in search of a new one. After some time, he finds Lust again, who is quick to replace his old Red Stone for her own gains.

Lujon was engaged to Lydia at a point, however he falls in love with Lust when they meet. On his wedding day, he leaves Lydia at the altar and she rushes off to find him. When Lust and Lujon later meet, they exchange a brief hug, when he confesses his love for her, she kills him, instantly breaking his stone. He is then fossilized by the disease that kills every person in his town. Lydia finds him and becomes fossilized in his arms.

Trivia

 * Lujon's behavior reminds Lust of Scar's brother, who is both the Alchemist who made her and the lover of the person she was meant to replace. Ironically, Lujon's seiyū, Takehito Koyasu, went on to voice Scar's brother in the 2009 anime.
