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) 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

This guy is crazy. the fetuses, the screaming face shape, the fatally wounded music... only thing more creepy is sonic. Exe, and I'm not scared of them anymore but they were so SCARY AT FIRST

The father of all creepy bosses. Giygas literally destroyed himself with his incomprehensible power. He's literally evil himself! Hard to believe that in MOTHER, he was just an angry grey alien. - Sovereign-Robo

Giygas’ guilt became too much for him to contain and his psychic powers go out of control, spawning the embodiment of evil and darkness with infinite power at his disposal but with giygas’ concience gone he now acts only on urge. As stated by porky he has become an “all-mighty idiot”

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.

Blood, in a KIRBY game. It's also so unexpected. A dead spirit, that you killed, and did I mention this is a KIRBY game?

3 Omega Flowey (Undertale)

Can't believe I'm saying this, but Omega Flowey should be number one! The twisted music and his evil laugh gave me more headaches in one minute, than Lavender Town did in my entire life. I used to be so scarred from this guy, I couldn't look at him for months. And no, I'm not exaggerating! - TheDancingGhost

Be honest, the first time you saw that, thing, you freaked out like a little girl. I MEAN IT WAS A FLOWER AND NOW THIS FREAK OF NATURE? Thanks Toby.

The "Omega" upgrade on Flowey makes him look like he took steroids and even when he gets mad at you he looks like he took meth

I won't say Photoshop Flowey is scarier than Giygas, but he's damn close. That laugh... ugh... - Sovereign-Robo

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. - MegaLucario58

Very fitting...

*DING! whoosh whoosh whoosh*

5 Pyramid Head (Silent Hill) 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 ...more

Everyone loves a pyramid-wearing blade murdering freak! He has made several appearances throughout the Silent Hill series and others as cameo like I Wanna Be The Fan Game and others. - MegaLucario58

6 Andross (Star Fox 64) Andross (Star Fox 64)

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. - MegaLucario58

He's so big!

"I've been waiting for you, Star Fox. With my mighty intellect, the Universe shall soon be mine to command, as I see fit. Opposing me... is truly a death sentence. Heh heh heh heh heh heh heh heh... just ask your FATHER." ~ Andross

I mean, why are people so all about "Star Wolf is the coolest! "? ANDROSS is where it's at. He invaded the WHOLE DAMN LYLAT SYSTEM. And he's literally reduced himself to head-and-hands. Disturbing indeed! - Sovereign-Robo

7 Photoshop Flowey (Undertale)
8 Lavos (Chrono Trigger)

I hate Lavos!

9 The Broodmother (Dragon Age: Origins)
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. - MegaLucario58

I guess it's the big daddy's daughter?

The Contenders

11 Mother Brain (Super Metroid) Mother Brain (Super Metroid)

The body.

12 Bitores Mendez (Resident Evil 4)

Remember that tall guy or "the Big Cheese? " That is Bitores Mendez. If the boss battle isn't worse enough with him just all fine until you blow his legs off. HE BECOMES A CRAZY SPIDER THINGY! - MegaLucario58

13 Dead Hand (Legend of Zelda)
14 Blizzeta (The Legend of Zelda: Twilight Princess)

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

When I saw the "Not take mirror" part, I almost did a front flip over my chair

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. - MegaLucario58

Yeah that jumpscare gets me, Now I now how FNAF got created

15 Nemesis (Resident Evil 3)

Its nemesis, enough said

16 Majora (The Legend of Zelda: Majora's Mask)

The damn mask looks creepy already

17 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. - Garythesnail

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


18 Clotho (God of War 2)
19 Ansem (Kingdom Hearts)

That guy that is almost naked attached to a giant fleshy ship thingy? That's Ansem. I suggest you level up a lot before doing this. - MegaLucario58

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

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

The backstory behind this thing makes its appearance even more terrifying. - xandermartin98

21 Ballos's Final True Form (Cave Story)
22 The Amalgamates (Undertale)

"Welcome to my special hell."

23 Dr. Steinman (Bioshock)
24 Shadow Queen (Paper Mario,The Thousand Year Door) Shadow Queen (Paper Mario,The Thousand Year Door)

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.

25 Zero (Kirby)

He attacks you with blood and dark matter. Enough said

One second: aw! It's an adorable pink ball thing riding on a hamster!

26 The Masked Man (Mother 3)

You're fighting your own brother. He's mutated and evil. He beat up your dad. He's mindless. He's heartless. Your dead mother is speaking to you. The music is extremely unsettling. If you lose, the world is destroyed. What can be scarier?

The hole process on how the masked man came to be is disturbing he had all of his limbs eyes and ears ripped off and replaced with robotic parts if that's not creepy I don't know what is.

27 Big Daddy (Bioshock)
28 Snowdrake's Mother (Undertale)

Amalgates from true lab made me had nightmares and undertale is not a scary game

29 Matt Helms (No More Heroes 2)
30 Phantoon (Super Metroid) Phantoon (Super Metroid)

Considering that it's (yes, IT'S) somehow supposed to be the biological (? ) ghost of the original Mother Brain from Metroid 1, and also from just looking at its appearance in general, yes - xandermartin98

31 The Imprisoned (The Legend of Zelda: Skyward Sword)

Timers freak me out.

32 Big Sister (Bioshock)
33 Miracle Fassad (Mother 3)

It's a "miracle" he's still alive in this fight - xandermartin98

34 Spoiled Rotten (Wario Land 4)

All the bosses in Wario Land 4 are scary! Except for aero dent

When you face him he's so cute but then... The second form


35 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

36 Master Core (Super Smash Bros. 4)
37 Metroid Prime (Metroid Prime) Metroid Prime (Metroid Prime)
38 Master Fortress (Super Smash Bros. 4)
39 Beast Ganon (The Legend of Zelda: Ocarina of Time)
40 Porky Minch (Mother 3)

The scary thing about Porky is that he is a complete and utter psychopath, yet is eerily realistic. He was a normal kid, but due to his parents neglect, corruption by Giygas, and his own inner evil, he becomes arguably the worst Nintendo villain created. He essentially destroyed the world, tore families apart, and has created mass havoc. He had continued this reign of terror for 1,000 years, and was only stopped when he retreated into the Absolutely Safe Capsule, which, being Absolutely Safe, shut him in forever.

He's over 1,000 years old, is completely insane, and will never die no matter what happens to him. Worst of all? He represents the worst flaws of humanity. That's...terrifying. - DemonSpider253

41 Sans (Undertale) 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 more.

Very definite proof that even the most easygoing and fun-loving folks can be frightening, once you pushed their buttons more times, than you should have. - TheDancingGhost

42 Xord (Xenoblade Chronicles)
43 Endogeny (Undertale) Endogeny (Undertale)
44 Baby Bowser (Yoshi's Island) Baby Bowser (Yoshi's Island)
45 Spider Queen (Okami)

Okay, how is this thing only Number 62? Sure the boss is cakewalk, but this spider lady is super creepy, especially when It rams towards you! Not to mention the entire fight takes place in the dark! - TheDancingGhost

46 Onaga (Mortal Kombat Deception) Onaga (Mortal Kombat Deception)
47 Vladimir Makarov (Call of Duty: Modern Warfare 2 & 3) Vladimir Makarov (Call of Duty: Modern Warfare 2 & 3)

It all depends on how you use the term scariest.

48 Dr. Andonuts (Earthbound: Radiation's Halloween Hack)

After (SPOILERS: a short but sweet and very, very disturbing journey through his disturbed mind, fighting creepy enemies and discovering his repressed shame, guilt and homosexuality), you must kill him inside of his own mind... And he is absolutely FURIOUS, fighting back with all of his might. Also has "Megalovania" as his boss theme.

49 Dahaka (Prince of Persia Warrior Within)

So scary! Specially when he chases us

50 Golden Diva (Wario Land 4)
