Lujon is a character appearing only in the 35th episode of the anime. An alchemist Lust encountered years ago, Envy saw potential in him to advance their plans to make a Philosopher's Stone. After the Homunculi deliberately spread the Fossil Disease in his village, Lust gave him a Red Stone ring to use against the Fossil Disease. However, Lujon fell in love with Lust, and Lust began to feel the first stirrings of her humanity, as Lujon reminded her of her creator, Scar's brother. When they met again, Lust killed him to "fix" the mistake of getting him involved in the Homunculi's plans. Upon his death, everyone in the village fell to the disease, and none were left alive.

Despite Gluttony's pleading her, Lust did not allow Gluttony to eat Lujon's body after his death.

In the English dub, he also mentions the Ishballan God, Ishballa, and when using Alchemy, he frequently prays to him.

He resembles Scar's brother from the manga.
