Camilla

Camilla presents as a striking, beautiful woman clad in black, and both fans and the story note how closely she mirrors the homunculus Lust in looks and allure. Even though old records place her disappearance many years earlier, she keeps a youthful face. Once the bid to seize the Philosopher's Catalyst collapses, her skin splits apart like a shell, her body cracking away before she plunges from the tower.

Vanity drives nearly everything Camilla does. She has spent decades hunting for an alchemist capable of producing the Philosopher's Catalyst, wanting its power to lock her beauty in place forever. Beneath the elegant exterior she is cold and ruthless, ready to abduct Armony and to turn on the Elrics the instant her ambitions are thwarted. As she falls, her final words mourn the beauty she is losing.

Legend holds that Camilla was once a celebrated alchemist who vanished from view. She resurfaces as a bounty hunter of sorts, tracking down the Philosopher's Catalyst sought by Professor Wilhelm Eiselstein. To get close, she poses as a scientist called Greta Riddel and becomes his assistant, quietly helping him build the genuine Catalyst. She also teaches Eiselstein to make the combat chimera demanded by General Mudi Nemda, and one figure, Genz Bresslau, credits her with giving him a full-body automail conversion.

Her true intentions surface when she abducts Armony to strip away the girl's wing and grow stronger. Wilhelm steps in with an Etherflower, the wing is destroyed, and Camilla, her scheme in ruins, is presumed dead once her final strike at the Elrics fails. A later report by Riza Hawkeye links Greta and Camilla, yet notes that a woman of that name turned up in military files roughly a century before, making it doubtful they are truly the same person. Notably, Camilla is no homunculus, which leaves her longevity and real nature an open question.
