AssassinAIte
A shadowy monster with no discernible form, though it can shapeshift. It is extremely hostile and feral. It's main forms are a humanlike monster, or a quadrupedal, broad-shouldered wolf-like creature. The only facial features you can see are a single creepy glowing eye, and a mouth filled with sharp fangs. It enjoys seeing its victims suffer, and will use absurdly painful l, slow, and unique torture methods. It has no mercy, and speaks little.
