20 Most Terrifying Enemies In Video Game History

3. Hybrids/SHODAN - System Shock 2

Hybrids are essentially meat-puppets, humans under the control of parasitic worms which serve as a link between body and The Many; a hivemind AI organism with a fetish for flesh. Hybrids are fast, tough... and truly horrific to gaze upon, resembling an acid-eaten mass of tumorous pulp bearing a vague resemblance to the human form.

Believe it or not, that isn't even what really makes them terrifying; the really disturbing thing about these freaks is the fact that hosts are entirely aware of their fate, and will oftentimes beg for somebody, anybody to end their pain and suffering. And that's not still not the scariest thing you'll encounter aboard the Von Braun by a mile - no, that title belongs to SHODAN, a megalomaniacal, psychotic AI with a serious God complex.

With her flat, eerily unemotional voice belying her burning hatred of humanity, SHODAN's apparent omnipotence transforms the Von Braun's gleaming, metallic corridors into an inescapable nightmare of her creation. Boasting one of the greatest reveal scenes of all time, SHODAN is the definition of timeless evil.
