Jason Voorhees a child's voice before being submerged in toxic waste, and in "Jason Goes To Hell" where his spirit possesses other individuals. Online magazine Salon's Andrew O'Hehir describes Jason as a "silent, expressionless...blank slate." When discussing Jason psychologically, Sean S. Cunningham said, "...he doesn't have any personality. He's like a great white shark. You can't really defeat him. All you can hope for is to survive." Since "Friday the 13th Part VI: Jason Lives", Jason has been a "virtually indestructible" being. Tom McLoughlin, the film's director, felt it was silly that Jason had previously been just another guy in a mask,
Jason Voorhees "The New Blood". Since Jason had been submerged under water in the previous entry, the effects team wanted Jason to appear "rotted", with bones and ribs showing, and for Jason's features to have a more defined feel to them. Howard Berger was inspired by Carl Fullerton's design in "The New Blood", and wanted to incorporate the exposed flesh concept into his model for "Jason Goes to Hell". Berger designed Jason's skin to overlap with the mask, to make it appear as if the skin and mask had fused and the mask could no longer be removed. Gregory Nicotero and Berger
