Jeff's appearance depicts him as having a ghostly white face, white lips with a crudely carved smile, dark circles bordering his eternally open eyes, and medium length black hair. He is also always seen donning a bloodied white hoodie and black jeans and says go to sleep when he kills. Jeff is immortal stuck at the age of 19. Jeff has burnt off eyelids. He is extremely ruthless, brutal, sadistic, psychotic, and violent, commonly with a twisted sense of humor and a snarky impulsive attitude.
