Films: Hypothermia (2010)
Height/Weight: That of an average human.
Summary: Ice fishing sounds like something a masochist would come up with. What could be more invigorating than sitting in the freezing cold for hours and hours waiting to catch fish that's probably already frozen solid below the ice?! Well, if you wanted a more exciting session, than you should really be careful what you wish for...
History: Somewhere in the wilderness there's a nice frozen lake where a family has gone to go ice fishing. Unfortunately, their plans go awry when one of them is nearly killed by something below the ice. Something very active, violent, and hungry. As it turns out, there's a man-fish living in there, and even getting struck by it is a ticket to death's door. The struggle between whether it should be avoided or killed is about to begin.
Notable Kills: Nothing special.
Final Fate: By the end of it all, only the women who came along are left alive. The gillman does catch up to them, but after one of the people talks to it a bit, it calmly leaves. It's amazing what a bit of negotiation can do.
Powers/Abilities: Can survive in freezing waters, and its claws/teeth are laced with a deadly poison that can cause amplified aggression and delirium.
Weakness: Anything conventional.
Scariness Factor: 3.5-Do you want to be dragged into sub-zero waters? Do you wish to be manhandled by a jet black fish humanoid with razor sharp teeth? Do you want to feel sheer pain as just a scratch causes your mind to unravel? If you answers to all of that is appropriately no, then at least take solace in how the costume does look a bit on the cheap side. That doesn't mean you shouldn't proceed with caution.
Trivia: -This film was done on location in the Great Sacandaga Lake, New York. That said, the underwater scenes were done in an indoor pool.
-Many fish can actually survive quite well in freezing waters, but none more so than the Antarctic toothfish, which can form antifreeze glycoproteins in its bloodstream to prevent being frozen. This is what enables it to be an effective predator.
