Lust - Yenra Picture Wiki
Lust of Fullmetal Alchemist, the "Ultimate Spear", appears as the first homunculus in the series as a shapely woman who primarily works in the shadows, acts as envoy for her leader in both iterations, and encourages humans down her desired path.
She can extend her fingers to great lengths, which are capable of cutting through virtually any substance. After leading an effort to capture Barry the Chopper, her plans backfire when Roy Mustang infiltrates the homunculi's secret lair.
Mustang repeatedly blasts Lust with flames, ultimately killing her after depleting the power of her Philosopher's Stone.
