|Intended Victim||Amerigo Tranmer|
The Sinful Colossus was the first "boss" demon that Amerigo encountered once in Hell. It was humanoid in appearance much like the Scythe Sinners, although the Sinful Colossus had a single eye on the left side of its face. It did, however, share the same gaping mouth as the Scythe Sinners. Its body was covered in a sort of linen cloth similar to the wrappings of a mummy, it had the legs of a goat, and its arms were nothing but rotting bones held together by thin strips of muscles.
