7. Jason Voorhees (Water/Pretend To Be Him Or His Mother)
Jason Voorhees is the near-unstoppable killer from Camp Crystal Lake. Bullied as a child for his deformities, Jason was thought to be dead after having drowned trying to escape his bullies. His Mother would first look for vengeance for his treatment and his supposed death by going on a killing rampage at Camp Crystal Lake but, after having been shown to have survived his apparent drowning, he takes matters in to his own hands and goes on a killing spree of his own. However, after having almost drowned, he has shown on occasions an unwillingness to go through water in order to get to his potential victims (such as in Freddy Vs Jason when, in Freddy's dreamworld, Jason stops in his tracks when he is about to strike Freddy thanks to a wall of water falling between the two characters). He also stops in his tracks whenever he sees an image of himself as a boy or one of his Mother - and given how stupid he is, all you need to do is put together a shoddy costume to resemble either of those two people and you've handed Jason his ass. Note: The water weakness tended to be inconsistent. Don't rely on it indefinitely.
