Sloth (2003 anime)

Sloth was created when the Elric brothers tried to revive their mother, Trisha Elric. Sloth is the product of Edward's sin, being a sloth for not taking time to appreciate his mother even in her death. Dante visits the mass of organic substance that would eventually become Sloth, feeding her a red stone that allows her to achieve and maintain a human form. Sloth is able to assume a watery composition, which she can use to drown others by grabbing hold of them. With a red stone inside her, she is perfectly capable of reforming herself but at a slow pace. Sloth assumes the identity of Juliet Douglas, a secretary to the Fuhrer (Pride). Sloth constantly suffers from memories of raising the Elric brothers. Determined to prove to herself that those are Trisha's memories, not her own, she longs to be able to kill them, as a mother could never kill her own sons. She worries that, as time goes on, she will be forced to accept that she really is simply a resurrected Trisha Elric, and that she will grow to love Edward and Alphonse. Instead of the Elrics, she develops a mother-son relationship with Wrath, and the two stick together during the second half of the anime. During a battle with the Elric brothers Wrath, having unknowingly merged with Trisha's remains earlier, merges with Sloth's body to help her in combat. This leaves Sloth paralyzed, allowing Edward Elric an easy opportunity to convert the water in her body into ethanol, which then evaporates into the atmosphere. Just before she disappears for good, Sloth smiles kindly and says: 'Nicely done, Sweetheart. Clean up after yourselves and take care of each other.' This indicates that Sloth had been lying; that she had in fact cared about Edward and Alphonse all along.

She had a cameo in a later episode when Envy shapeshifts into her in a failed attempt to guilt trip Ed into letting him live.
