Top 10 Scariest Video Game Bosses

Have you ever had that one boss that traumatized you as a child? See if he's on the list here!
The Top Ten
1 Giygas (Earthbound)

For me, part of what makes Giygas so uniquely scary is how he contrasts to the rest of Earthbound and to other bosses. The rest of the game is colorful, quirky, and cheerful. The overall dark and creepy feel of the fight makes it seem so out of place. If this fight was from almost any other game, it wouldn't be as scary. It's almost this element of surprise that makes him scary

It's giygas. A being composed of all the souls and hatred of entire GALAXIES. May I remind you, this thing is from the 5th dimension, hosting far more power then almost any videogame boss to EVER EXIST. He's able to manipulate the minds of anything and/or EVERYTHING. May I remind you, he LITERALLY only has one weakness. ((also, he contains so much power and hatred, he can't even comprehend himself. he cannot grasp his true form, and at the same time, you can't as well. that's INSANE power for something to contain)

2 Zero Two (Kirby 64)

The scariest part about Zero Two, is the bad ending where he possess the Ripple Queen, and gives you that evil smirk that indicates that he's now going to transform Ripple Star into a communist dictatorship.

What freaks me out the most is the vine in Zero Two's underside, I mean how is that even possible! Kirby is my favorite video game series, and I'm shocked to see something this horrifying in it.

Most of Kirby is a cute amd quirky gaming experience. A lot of the enemies like Waddle Dee or not aggravated Scarfies and bosses like Dedede and Paintra are somewhat cute. But then hidden below all the cute happy-go-lucky, we have pure nightmare fuel...

3 Omega Flowey (Undertale)

After your first playthrough in the pixelated, whimsical/emotional Undertale, you are taken completely off guard by being robbed of your chosen victory by the very first thing you encounter in the game, a flower. He then proceeds to crash your game, "erase" your file, and force you into a terrifying battle against his final form, a morbid photorealistic mess of eyes, teeth, and vegetation, all whilst being bombarded by heavy danmaku firing patterns and a very heavy breakcore track. If you lose the battle, the game crashes AGAIN and upon opening, the boss battle is initialized once again. Nightmare fuel.

4 Sorrow (Metal Gear Solid)

By far one of the creepiest, and most interesting, boss fights. The worst part is that you suffer longer if you killed a lot of enemies throughout the game, so your past decisions come back to haunt you.

When you battle him you see visions of the soldiers you killed. And, one of his moves is a screamer.

5 Andross (Star Fox 64)

The android form of him is in my opinion, a lot scarier, because once you shoot his eyes out (this is the easy boss), he's reveled to be a giant head of creepy circuitry. I literally screamed when I saw that for the first time. And it only makes it scarier because I was playing the 3D version on the 3DS.

It's just a giant gorilla head with two heads and shoots at you... WAIT. When you destroy it's shell it turns out to be a BRAIN with VEINS and EYES. It seems like Nintendo really messed up on a E-rated game.

6 Pyramid Head (Silent Hill)

You hear a slow scraping along the floor... Like metal grinding on Metal. As you look towards the sound, you see a massive man in a bloody smock walks out. At his feet are hundreds of cockroaches, piling over each other in an effort to get to you. As you scream in terror, he turns towards you, and stops, motionless for a few seconds. Then he starts his slow walk towards you, as once again, you hear the sound of his massive blade grinding on the metal floor. You race down the corridor, fearing for your life at the hands of this monstrosity, this abomination of a creature. You come to a door, and in it, you see salvation, a way to get away. You turn the handle... and it's locked. Slowly your flashlight peeters out, as you collapse to ground sobbing. Suddenly, a powerful pair of hands grab you and start dragging you away. "This is the end" you think, as you scream your denial, not accepting your impending death. Suddenly, your dragged into a room, and the metal double doors at it's entrance are closed, not by the abomination, but by a young woman. "Get a pipe!" the woman yells, as you spring into action. "Quick!" she yells, as the doors shake with the force of the man pushing it. You finally break the pipe loose, and the woman wedges it in the door, blocking it from opening. You breathe a sigh of relief, now safe from the horrors outside. Until once more, the scraping starts again. "You hear that? " the woman asks. All you can do is nod in terror. The scraping stops, and for a brief moment, you dear the believe that the man has left, until a massive blade bursts through the door, Nearly skewering you. Bugs start to pour through the hole in the door, flooding the floor with them almost instantly, biting your exposed ankles. The blade rams the door again, and again, making the hole bigger each time. More and More bugs fill the room, until the blade stops it's barrage, and everything is silent for a second. Until a massive arm... more

7 Lavos (Chrono Trigger)
8 The Broodmother (Dragon Age: Origins)
9 Mother Brain (Super Metroid)
10 Little Sisters (Bioshock Series)

Children possess a natural creepiness that has been tapped into for thousands of iconic horror movies, fiction thrillers, and everything that the Olsen Twins have ever done. Their presence in this groundbreaking first-person shooter, however, makes Little Damien's evil ways seem harmless enough to replace Jonathan Lipnicki in Jerry Maguire. They roam the diseased halls of Rapture with the menacing Big Daddy and when they spot you, they order their drill-bit toting protectors to rip out your guts and feed them back to you. If you harvest their "Adam," they turn into wiggly little slugs. If you save and release them, they grow up to get their own reality show on MTV.

The Contenders
11 Dead Hand (Legend of Zelda)
12 Bitores Mendez (Resident Evil 4)
13 Blizzeta (The Legend of Zelda: Twilight Princess)

Oh, it's just a little helpless thingy I forgot it's name. NOPE.. When it looks into the mirror it will probably make you jump if you weren't expecting it.

Okay imagine this. You walk with your girlfriend to her house. She looks into her mirror and then... NOT TAKE MIRROR

14 Clotho (God of War 2)
15 Majora (The Legend of Zelda: Majora's Mask)

After going through all the horrors in the game, defeating Majora was one of the best feelings I ever had when I first finished the game!

16 Elder Princess Shroob (Mario & Luigi: Partners in Time)

Seriously...I had to add this? The first phase isn't scary, but the second is just mortifying.

I give for that "This is scary from the sorrow! And give 13 for this so very scary boss battle!

This Boss is also downright hard too.

17 Nemesis (Resident Evil 3)
18 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.

21 Ballos's Final True Form (Cave Story)
22 Baby Bowser (Yoshi's Island) Baby Bowser, referred to simply as Bowser, is the infant version of Mario's arch-nemesis Bowser, and the main antagonist of the Yoshi's Island series.

23 Shadow Queen (Paper Mario,The Thousand Year Door) The Shadow Queen is the overarching antagonist and final boss of Paper Mario: The Thousand-Year Door. She is widely considered one of the most difficult bosses in the Paper Mario series.

In other words, instant nightmare fuel.

A Demon Summoned By The Leader Of A Cult Who Is Killed by the Demon,Who Possesses Peach and Becomes the Final Boss,and if you lose,the world becomes shrouded in darkness.

24 Hades (God of War III)

He's not really scary. Just intimidating. He's actually not that hard if you've got the moves down.

So badass costume, design. He is the god of underworld. So hard and scary boss fight

25 The "Phaze Destrortur" (Radiation's Halloween Hack)

The backstory behind this thing makes its appearance even more terrifying.

"At the time I didn't know why I was so scared. Now I know why...
That machine was a death trap."
