Watchmen

Watchmen (탐색병, Tamsaegbyeong, "Seekers", "Explorers") is a giant humanoid creature on the Tower that lived on the Floor of Death as "microorganisms" of the decayed body of the 43rd Floor Guardian. They are part of the Gatekeepers System which prevent intruders from entering the Floor of Death.

Appearance and Design
Watchmen is a very tall, giant humanoid muscular creature with weird looking head that looks like The Bull Shinheuh, except with two eyes and two pointy ears, which is more like Anubis. Their neck and lower body part (from waist to foot) was covered with black fur. They have grey skin and three red claws.

Powers and Abilities
The Watchmen is relatively strong, but they can be defeated by strong Regulars like Princess Androssi Zahard. They aren't immortal like the Stag Beetles.

When a Watchmen or an Explorer gets killed, there is a "Light Bulb" that will come out from inside their body in order to buy time for the Eye Bugs to pinpoint the location of the intruders, which then calls the Stag Beetles Gatekeeper to the enemies’ location to support the Watchmen.

Notes and Trivia

 * The giant bugs will continue coming up on the Floor of Death. Since the Floor of Death is largely composed of a decomposing corpse, and corpses have bugs, so one of the settings is that they have lots of bugs.
