Sloth

Sloth (Japanese:スロウス, Surōsu) is the name given to two very different homunculi due to the sheer differences between the anime and manga.

In the manga
In the manga, Sloth is not introduced until midway through the series, where he is revealed to be a large, muscular, dim-witted man. He is tasked with digging a gigantic transmutation circle beneath Amestris to be used in turning the country into a Philosopher's Stone. Though he is briefly impeded in this job when he runs into the Elric brothers at Briggs Fortress, he is allowed to continue his work, finishing the circle in chapter seventy-eight. Just as his name, Sloth is always wanting to rest and finish his job so he can stop working. When Greed is captured by Wrath, he asks about Sloth and Lust answers saying he is still working, meaning he was already making the tunnel before Greed left the group one hundred years before.

After finishing the transmutation tunnel, he acted as Father's personal bodyguard, following him when he took direct control of the army and sleeping near Father's throne when he has nothing else to do. In chapter 91, he was sent to deal with Major General Olivia Armstrong when she took one of the corrupted generals of Central as hostage, killing the hostage in a surprise attack. He is currently fighting against the two Armstrong siblings.

In combat, he uses his fists and the chains on his wrists coupled with his astonishing physical strength. In his most devastating attack, he hurls himself towards his foes at incredible speed, like a living missile. He claims to be the fastest homunculus.

His tattoo is located on his right shoulder blade.
