Cancer

Cancers are crab monsters that live near water such as oceans, rivers, etc. They have the upper body of a woman, a lower body covered in a hard shell, and one of their five pairs of crab legs have become giant pincers. Boasting freakish strength, these pincers can even twist and tear off the iron armor of their prey but are also proficient enough at delicate, dexterous movements that it is no issue to remove the clothing of their prey without ever tearing it.
