The Humanoid is a monster in the Facility . It can be seen during the elevator monsters scene where it is seen inside its prison cell behind the Giant Toad . It was released during the System Purge but it was not seen during the chaos.
He is depicted as a humanoid monster that looks just like the Wheel of Fate in the House of the Dead 3 video game. It stands like it as well. The only difference may be its skin color and it does not have the symbol of the sun on its torso and it does not have the telekinetic wheel with bursts of psychotelekinetic energy.
It is unknown as it cannot be seen in such a clear view. But from seeing it from a distance, it can be considered to be a reference to the Wheel of Fate in the House of the Dead 3 video game.
