Unlike her lazier manga counterpart, this Sloth is rather apathetic (another meaning to the sin of Sloth). Sloth is actually the calmest of the homunculi, rarely getting worked up and shows no concern for the lives of others (except hers). She can be very snide and patronizing at times (as she was towards Greed). Sloth acts as a mother-figure towards the young homunculus Wrath. She does appear to suffer from her previous memories of being once the mother to the Ed and Al (again another meaning of the sin). Because of this, she resolved to kill them to free herself from her torment.
