This is an Alien for a sci Fi horror story I have kicking around. Essentially the story is a mix of alien, predator, seasoned with dead space and the thing. I want it to be pretty heavy with body horror. The main characters end up on a ship filled with twisted creatures who turn out to have been the crew they were sent to save. This alien throughout the story is seen as an animalistic threat but over time appears to get smarter (thing the raptors from Jurassic Park) until it is revealed that the alien, using alien science, mutated the crew into the monsters (monsters who are fully aware and know what's happened to them). Everyone dies except the main character who is also mutated (but is still somewhat recognizable) the alien gets away and the authorities find the main character.
