The Monster

* Full Head
* Scaly Eye

**The Monster**, also known as The Frog, is the main antagonist of Iron Lung. It lives in the blood ocean of the moon AT-5, and hunts down the player throughout the game. The player sees the Monster several times before it bursts through the back of the Iron Lung's hull when the player goes to the back of the submarine to take the last photograph, killing the player and ending the game.

It is unknown whether the Monster seen in the image and the Monster that kills the player are the same organism. There is also speculation that the player is being hunted down by two separate entities, as the large eye seen in one of the photographs does not appear to match the eyes of the other sightings of the Monster. However, all are labeled "Monster" in the game files, suggesting there is only one.

## Appearance

The Monster (as seen in the game's final jumpscare) has sharp teeth and a large jaw, and appears to have a head about as large as the player. Its eyes are somewhat frog-like due to the way they protrude from its head, as well as their similarly black sclera. The species of the Monster is unknown, though it is speculated that it may be based off a frog, a frogfish, or an anglerfish.

The Monster (seen in the Iron Lung's camera) has a large eye with a dark, round pupil, surrounded by scales. As this image is in black and white, it is unknown what color the scales and eyes are, if they are different from the other images. The size of the eye suggests an incredibly large creature, which contradicts the stature of the Monster seen at the end of the game. When viewing the Monster out-of-bounds, its face extends to a long, serpent-like body.

It is unknown whether or not the Monster caught on camera is the same entity as the one which ultimately kills the player. Despite the glaring differences in their appearances, it is important to account for the wildly different mediums and perspectives of the images, as well as the game's limitations using .png files. As such, it is difficult to determine if these factors are enough to make a creature look as different as it does in the two pictures.

## Behavior

The Monster is first seen only observing the player, and appears to be able to move quickly. However, as the game progresses, the Monster becomes more aggressive. It is speculated that the Monster is the cause of the jolting of the Iron Lung on two occasions. Ultimately, the Monster attacks and appears to kill or drown the player, dispersing the remains of the Iron Lung.

## History

Little is known about the Monster, but it is speculated that the Monster was also the cause of the destruction of the SM-8. It is also unknown whether the Monster was on AT-5 before or after the Quiet Rapture.

## Trivia

* The Monster is featured in the game ULTRAKILL's secret level "5-S: I ONLY SAY MORNING".
* By hacking the game, the image of the eye appears to be a flat plane with an image texture on it that covers the entire camera's vision.
	+ The eye will actually follow the player's camera until the player triggers the photograph.
* A beta variation of the Monster's roar was found in the game files, labeled "CreepyRobotSound.ogg", which can be heard here. This was later changed to new one heard multiple times through the game.
