Top 10 Most Disturbing/Creepy Bosses in Video Games

A boss, otherwise known as a very difficult enemy to kill, is an enemy in games that you will encounter, most bosses require a number of attacks/strategies to defeat it. Anyway some bosses in games can be very creepy.
The Top Ten
1 Giygas - Earthbound

Giygas, oh Giygas. This thing is the definition of trauma. It even was inspired by trauma. Earthbound is a cutesy game. until you go in the cave of the past, when everything cute drops, and you are forced to wander the caves of forgotten times. Then, you enter a crack in the wall, and enter the lair of the almighty idiot. Even Pokey claims he is absolutely morbid. The fight itself is tense and terrifying. Giygas' final form is even stranger, as he morphs into a cloud of terror. The ONLY way of weakening it is PRAYING. Praying to your god that you will be safe. In fact, the Omega Flowey fight from Undertale had a line when it said "Cry into the darkness", a reference to the Giygas fight when the pray action is used. You pray to save yourself, for someone to hear your cries. But, it gets all dropped when you realize it's original form was just an angry alien. So, what will I rate it out of 10?

9/10 spook factor, very spooky

Giygas is infamous not just for the music and fetus theory but also for the feelings of isolation, loneliness, and hopelessness players felt while fighting him. That makes him truly terrifying.

I think this should be number 1. You can hardly tell what he is other than a fetus-like entity. And also the music in the fight... So creepy...

Earthbound may be an old game but there has been nothing quite like Giygas before or since!

2 GLaDOS - Portal GLaDOS is a fictional artificially intelligent computer system appearing in the video games Portal and Portal 2. The character was created by Erik Wolpaw and Kim Swift and voiced by Ellen McLain.

Imagine seeing glados in a dark room,that creepy yellow just staring at you

At least she gives you cake... Oh, it's a lie.

The voice alone is creepy

3 0² - Kirby Series

The source of Dark Matter as they are both final bosses of Kirby's Dreamland 3 and Kirby 64. In Kirby's Dreamland 3, if you keep on hitting it in the eye, it will pop out and drip what looks like blood and continue fighting. But what's worse in Kirby 64 is that it returns as what it looks like a fallen angel, crying "blood", and it's weak point is that green, spiky tail under it. Man, Nintendo just loves putting some creepy final bosses to contrast the light-hearted, cute and cuddly Kirby games.

WHO THOUGHT THIS WAS OK FOR KIRBY?! He's a cute little marshmallow dude!

I have not seen nor played crystal shards

Blood. Blood. Blood everywhere!

4 Nihilanth - Half-Life & Black Mesa

This creature has the ability of speech. When It talks to Freeman, it's actually referring to one of the hidden characters (G-Man).

5 The Icon of Sin - Doom 2: Hell on Earth
6 Majora's Mask - The Legend of Zelda: Majora's Mask

This boss scares the crap out of me. Imagine a heart shaped mask popping out of the wall growing tentacles, then arms legs and an eye ball, growing muscles with the eye ball forming into a head sounding like judge doom being tortured. what?

7 Psycho Mantis - Metal Gear Solid
8 Omega Flowey - Undertale

Omega Flowey is an example of a game that takes the cutesy out at the end, and replaces it with the eldritch. Omega Flowey is an eldritch abomination, just looking at it will make you think "What the heck was Toby thinking when making this?" This thing is comprised of metal, flesh, and plants. And this thing was formed when it absorbed 6 of the souls, what happens when it absorbs 7?

Spooky level:
8/10 very spooky

Honestly this is one of my favorite bosses of all time and he's truly terrifying considering the entire game was pixelated up to this point then you get to him and he's a photorealistic nightmare as well as changing the way fights work in the game from turn-based to complete bullet hell with some of the most insane attacks. Plus that laugh and music. Also the fact he can shut off the game at certain points, heal all his health after you've depleted all of it, kill you over and over and still have time to make creepy remarks and gloat, Your Best Nightmare he certainly is.

Contrasting the SNES-like art style of the game, Photoshop Flowey manages to be actually one of the toughest bosses in the game. Though I haven't played Undertale, his art style alone is enough to give players nightmares.

It's like a mix of 400 lbs. of venus fly traps, the Rakk Hive, and a robotic god that you have to fight inside hell.

9 Randy Tugman - Dead Rising 2

A guy who is determined not to die a virgin. So he kidnaps this poor woman and tries to marry her. Also he is unattractive in every way. He's overweight, rude, and he wears a fetish costume at his "wedding". He kills his father with a giant chainsaw (accedental, and his father is the pastor.).
He's like Dylan from Dead Rising 3 and Jo from Dead Rising.

10 Solaris - Sonic the Hedgehog 2006
The Contenders
11 Antoine Thomas - Dead Rising 2

He's a creepy chef who, after losing his chance of fame due to the zombie outbreak, tries to kill a poor woman and cook her flesh in a dish. He did it with others. During the fight, he replenishes his health by eating his human cuisine. EWWWW!

12 Dorothy - Galerians
13 Harlan Wade - F.E.A.R. 3
14 Wither - Minecraft

Hmm, let me check off the scary and disturbing stuff on the list:

1. Three large, black heads connected to the body with thin necks. Check.
2. Ribs and bones stick out of the body (but not through the skin). Check.
3. The color of the wither is dark and gloomy. Check.

I think this abomination checks out as a disturbing and creepy boss to Minecraft.

That thing's got 3 heads, how can that not be creepy?

15 Wizeman the Wicked - Nights Into Dreams
16 Michael Reynolds - Illbleed
17 Abstract Daddy - Silent Hill II
18 Mimi - Super Paper Mario

She's this little girl who's kinda like a cross between The Exorcist and The Thing. When Mimi transforms, the snapping of her neck is already the worst thing that could happen before her whole sequence! Oh, and she could be an homage to the final boss of Resident Evil 4.

It's like watching a small girl turn into something similar to a mix of something from "The Mist" and "The Thing", but it's on a budget on the Disney Channel.

The creepiest thing about this boss is in the mansion where when you stay in one room for a while...
SHE COMES FROM NOWHERE!
No to mention the black background in Castle Bleck makes her third fight seem like its just a floating head.

19 Calypso - Twisted Metal
20 Scissorman - Clock Tower
21 Crocomire - Super Metroid

His death is the reason why he's on the list.

22 Sans - Undertale Sans or Sans the Skeleton is a character in the 2015 RPG Undertale created by Toby Fox. He is a lazy, pun-loving skeleton who is a supporting protagonist in the "pacifist" and "neutral" routes of Undertale, and a heroic antagonist/final boss of the "genocide" route. He is known for his incredibly difficult boss fight, bad puns, and the phrases "geeetttt dunked on!!!" and "you're gonna have a bad time." He is also named after the font "comic sans." Known for also being Ness from the Mother series. (known as Earthbound in Western territories.)

The attacks are badass and Sans is amazing. The only disturbing thing about this final boss is how he guilts you on how you brutally murdered everyone and how how you killed his brother and friends.

The reason why he's low on the list is because he isn't that creepy. I mean, he's civilized, wears a jacket and shoes, and the boss theme is badass.

23 Marx Soul - Kirby: Super Star Ultra

When you defeat him, his ear-raping scream and unnatural gape are his cream of the crop!

24 Perfect Dark Gaia - Sonic Unleashed
25 Onslaught - Marvel vs. Capcom
