6. Water (Jason Voorhees)
Jason Voorhees is the main villain of Friday the 13th Part II and all of its sequels (and its remake) and a nigh unstoppable killer. Believed to have drowned when his attempts to escape some kids who were teasing him resulted in him jumping in to the lake, Jason's body was never recovered and he had actually survived. He stalks and brutally murders the inhabitants of and visitors to Camp Crystal Lake, due to a burning desire to avenge the death of his beloved mother, Pamela, and the abuse they received - thanks mostly to Jason's physical deformities. Even after his numerous apparent deaths, Jason continues to rise to murder again - including being summoned by Freddy Krueger to make the people of Elm Street remember him (which we'll get to later) - and almost nothing will stop him. Apart from water. Thanks to Jason's traumatic experience as a kid, he is terrified of water, as shown in Freddy's dream-world when he is about to attack Krueger but is halted in his tracks by a falling stream of the wet stuff.
