Sloth appears in two distinct forms across *Fullmetal Alchemist* continuities. In the 2003 anime, the homunculus emerged accidentally from Edward and Alphonse Elric’s failed resurrection of their mother, Trisha. Dante refined the resulting organic mass using red stones, imprinting Trisha’s appearance onto Sloth. Operating under the alias Juliet Douglas, she became Führer King Bradley’s secretary while covertly serving Dante’s agenda. Her abilities included liquefying her body into water for espionage, mobility, and drowning targets. An Ouroboros tattoo mirrored Izumi Curtis’ flamel mark above her left breast. Emotionally detached and apathetic—interpreting sloth as indifference—she resented the Elrics for inheriting Trisha’s memories, which fueled her existential anguish. Determined to erase these memories, she sought to kill the brothers to assert her independent identity. Though posing as a maternal figure to Wrath, her dying words exposed this pretense as hollow. Her demise followed Lust’s betrayal and Wrath’s interference, culminating in Edward transmuting her body into ethanol, causing evaporation. The manga and *Brotherhood* iteration, crafted by Father, embodied sloth as a hulking, lethargic homunculus tasked with digging a nationwide transmutation circle. Marked by wrist chains and a red node over one eye, he wielded immense strength but loathed exertion. His regeneration lagged due to prolonged hibernation under Fort Briggs depleting his Philosopher’s Stone. Despite his sluggishness, he unleashed sporadic bursts of uncontrollable speed, symbolizing squandered potential. During the Promised Day, he clashed with Olivier and Alex Armstrong, enduring their coordinated strikes until Izumi and Sig Curtis joined the assault. Impaled on an alchemic spike, he dissolved while voicing relief at ending the labor imposed by Father’s plans—a stark irony given his aversion to effort. Both versions avoided direct homunculi interactions: the 2003 Sloth answered solely to Dante, while the manga counterpart focused exclusively on tunnel excavation until his final battle. The anime’s conclusion in *Conqueror of Shamballa* showed Wrath moving forward independently, aligning with Izumi rather than pursuing reunion with Sloth.
