Greed is one of the Seven Homunculi in the anime series Fullmetal Alchemist. Known as the 'Ultimate Shield,' Greed has the ability to rearrange the carbon in his body to make his skin as hard as diamond, making him nearly impervious to physical attacks. Unlike his fellow Homunculi, Greed desires independence and material wealth, which leads him to betray his creator, Father. His rebellious nature and complex personality make him a unique character in the series, often acting as an anti-hero rather than a true villain.
