Monstrosity

The Monstrosity is the fusion of Subject 2, Parker, and Security Guard 2 (Via Parker). It serves as a minor antagonist in Subject 4.

Appearance
The Monstrosity includes features from all three of its components. Security Guard 2 manifests as shoulder padding.

Features from Subject 2 include the mushrooms scattered about the creature, along with three of the eyes and the general shape of the mouth.

From Parker, the veins and melting skin are present, along with the two central eyes.

Unique to the Monstrosity is the lack of bottom limbs. Instead, a giant blob comprises the lower half. Additionally, the eyes and mouth are connected by veins, which expand and contract when the mouth moves.

Personality
The Monstrosity has no personality. Its only objective is to spread and assimilate.

Gameplay

 * In the temperature room, the Monstrosity spews out pustules of goop, occasionally body slamming into walls to navigate across the room.
 * If the player is in the same area as the Monstrosity, it will automatically attack them and kill them.
 * If the player is to the left of the monstrosity during a body slam, the player will get crushed.
 * When the Monstrosity releases pustules, if the player is adjacent to the Monstrosity, they will get exposed to the pustules.
 * The only place of safety is across (or two areas away) from the Monstrosity.
 * When the player turns down the temperature at all the valves, the Monstrosity will approach the player before crystallizing due to the temperature. Then, the player uses the ax to finish the job, shattering the Monstrosity into pieces and preventing regeneration.

Trivia

 * The Monstrosity has the first onscreen death in the Animal508 horror universe.
 * Though only appearing in the 5th part out of 7, the Monstrosity is arguably the main boss in Subject 4, primarily due to the set up of its stage.
