King Crimson has a humanoid appearance, similar in build to Diavolo, but narrowly surpassing him in terms of musculature and size. The skin of his body is covered by a diagonal grid, except for his face, neck, shoulders, elbows, groin, knees, and feet. Its eyes comprise sharp orifices of a steep inward slant, really angry and mad stand that controls his user, can erease time and see 10 seconds in the future, is strong as hell, dosent lets his Diavolo talk.
