Muscle Mimic

Demons that resemble treasure chests. When a warrior approaches with no caution, intending to pillage the "chest," the Muscle Mimic retaliates with an often fatal punch (five tons of pressure per square inch) from an arm that it forms out of its side. Muscle Mimics also have the ability to shape-shift and copy the appearance of a given human, albeit with spectacular muscles. Some chaotic lawful members of the species, looking for a bit of easy cash, have been recruited by Lord King God University to test students' observational and fighting abilities.
