Maniacs

The maniacs are the main antagonists of Hotel Insanity. No identity is ever provided for any of the three that are looking for you. They will take away your health until you die.

How
Each maniac has a weapon. Two of them have knives, while the other one has a small, red axe. The maniacs will try to hunt you down by wandering randomly throughout the hotel until they find you. If they see you get into the elevator, they try their best to follow you to whichever floor you're going to. They take the stairs.

Every time a maniac sees you, they let out a small, quiet roar/hiss and start chasing you. Unlike Granny, they will not speak when they lose track of you, or ever. Every time you come in contact with them, they slice you and you lose three health points. They will keep slicing you until you die.

Consistencies shared between all 3 maniacs
None of them can speak and their mouths are stuck open, probably indicating some sort of injury during their early development years. They have no teeth or tongue, and the insides of their mouths are completely black. They emit a quiet roar/hiss when they've spotted the player, which can be heard clearly at 1:02 in the Hotel Insanity mod menu trailer [see Mod Menu for further reading]. The sound is strangely clear, as opposed to being muffled by something. This may be a sign of a lack of vocal chords, or it may just be because they don't have teeth or a tongue.

They often take a couple of seconds to notice the player, and even sometimes end up walking right past them. One example of this occurs at 0:58 seconds into the Hotel Insanity mod menu trailer [see Mod Menu for further reading]. Their eyes are orange-red, which, just like the lack of awareness of the player, also points to having a severe eye injury when they were young.

Their skin is white, but they look a little like they haven't taken a shower in a couple days. This is probably because they're in an abandoned hotel that's full of dust and spores, and also because they never change their clothes. Their nationality is indeterminate, but they're probably Swedish because the developer of Hotel Insanity [DVloper] is Swedish. They are serial killers.

Description of Maniac 1
He is wearing a blue, unfastened suit coat. It is stained around the collar, making it look darker than it is. His suit coat overlaps his pants, which are the exact same color as his suit coat, making it look like he's in a light blue onesie.

Underneath the suit coat is a brownish yellow button-down shirt tucked into his pants.

Around his mouth is a small amount of stubble. He has no teeth or tongue, and the inside of his mouth is completely black.

He has black hair on his head, with a small patch of it in the middle having been shaved off not too many days ago [This is evidenced by the fact that his hair has started to grow back].

His head is almost completely sideways. He is the only one who's head isn't on straight.

He has no eyebrows, but there are dark patches around his eyes that look as if he was given two black eyes and the healing process has just started.

His weapon of choice is a rusty knife with a cylindrical wooden handle, which he will never drop or let out of his hand.

Description of Maniac 2
Maniac 2 is wearing a beige sport coat that goes down to his knees and overlaps with his pants, which are the same color as his suit coat. He also looks like he's in a giant onesie, but it's beige, as opposed to light blue. The collar is stained a darker shade of brown.

Underneath the suit coat is a brownish yellow button-down shirt tucked into his pants.

Around his mouth is a small amount of stubble. He has no teeth or tongue, and the inside of his mouth is completely black. His hair color is golden, and the texture is curly. However, it isn't known if his head was also shaved a week ago. This is because he's wearing a hat with blue horns on it. Only a small amount of hair peaks out from under the hat. The hat itself looks like it should be white, but it's very dirty with lots of brown and green spots. The horns are electric blue, but that color is probably just paint because there are a few small white streaks on the horns that look like scratches.

He has no eyebrows, but there are dark patches around his eyes that look as if he was given two black eyes and the healing process has just started.

His weapon of choice is an axe with a long, cylindrical, wooden handle, which he will never drop or let out of his hand. The axe head is red, but the blade is silver, which probably means that it was sharpened recently.

Description of Maniac 3
Maniac 3 is wearing a white sport coat that goes down to his knees and overlaps with his pants, which are the same color as his sport coat. He also looks like he's in a giant onesie, but it's white, as opposed to beige or light blue. The collar is stained with what's clearly blood.

Like Maniac 1, a square of hair was shaved off the top of his head. His hair is also the same color as the hair of Maniac 1. Unlike Maniac 1, the hair of Maniac 3 hasn't started to grow back yet. His facial features cannot be known because he's wearing a white mask that's been stained with rust, golden paint, very old blood, or any combination of those items.

His shirt can also be seen through the crack in the center of his unbuttoned suit coat. It is gray and has no buttons, as opposed to the other two maniacs.

His weapon of choice is a rusty knife with a cylindrical wooden handle, which he will never drop or let out of his hand

Trivia

 * 1) Part of the game description says "Beware of the maniacs wandering in darkness. They'll hurt you."
 * 2) In the game trailer, they're also called maniacs
 * 3) Maniac 3 spawns on floor 3, Maniacs 2 and 1 spawn on floor 2. Each maniac makes a beeline for floor 1 because they know that's where the player spawns
 * 4) In the game trailer, at 35 seconds, the camera zooms in on one of the maniacs. Because the night vision goggles are being used, you cannot make out the fine details of the maniac and therefore don't know which one it is, but it's Maniac 3
 * 5) At 2:10 in the Hotel Insanity 1.0 mod menu trailer, it can be seen that Maniac 3 actually has no face. He only has eyes. It is unknown how he is able to produce the sound when he sees the player
 * 6) There is no way to defend against any of them
 * 7) The "roar/hiss" sound effect that the maniacs produce once they've spotted the player can be heard very clearly at 1:02 in the Hotel Insanity 1.0 mod menu trailer
 * 8) It is unknown why DVloper did not put identity/names on each maniac.
 * 9) The blue horns of the Maniac 2 was replaced in the Padlock Key handle of Granny and Granny: Chapter 2.
 * 10) Unlike Granny, If the maniacs see you hide in a room, they will break/rattle the door instead of opening or closing it.
 * 11) The roar of the maniac could be a voice from DVloper.
