10 Horror Movies With The Most Shocking Monster Reveals

10. Jason Voorhees - Friday The 13th (1980)

This might be cheating as Jason is technically the monster in every subsequent Friday the 13th movie, but it cannot be denied just how awesome the moment where he first reveals himself is.

After surviving her deadly stay at Camp Crystal Lake by defeating the psychopathic Pamela Voorhees, Alice Hardy floats out into the middle of the water on a boat, exhausted.

When she wakes up the next morning, the cops have arrived on the scene, and she's finally safe. Or so she thinks...

Just as Alice comes to, a grossly decaying body emerges out of the lake behind her, wrapping a gruesome arm around the young woman and dragging her under. This is the big screen debut of Jason "Wait Till You See Me In A Hockey Mask" Voorhees.

Pamela's son, whose supposed death was what turned her into a knife-wielding murderer, would of course go on to become one of horror cinema's biggest icons, but he is in his primordial, most zombie-like form here.

Still, the moment has gone down in history for a reason; it's historic, its horrifying, and it will make you think twice before ever going canoeing in a tranquil-looking woodland lake.
