Though named for the vice of lust, Lust does not appear to be lascivious herself, but rather an object of lust for others. Due to her enticing looks and high intelligence, Lust easily and effectively plays the role of manipulator within the Homunculus ranks, moving covertly around the country to lure weak-minded people (usually alchemists) into the clutches of Father to be used and disposed of when no longer needed.
Aside from her skills as a infiltrator and puppet-master, Lust has the usual Homunculus abilities of incredible longevity, astonishing regenerative capabilities and a great resistance to death that borders on immortality. Her own unique ability is to extend her fingertips into long, thin blades sharp enough to cut through just about anything with ease. The length to which her fingers are able to stretch has not been shown to have any particular limit as well, earning her the nickname "Ultimate Spear" among her Homunculus peers.
