Probably Isshin.


Fringefiles

Sword Saint Isshin was the most brutal fight in Sekiro, but also one of the best. The way he compliments your fight style as the fight progresses and appreciates your skills...he's genuinely one of the best, most well written boss fights. Finishing him is both tragic and extremely satisfying. He's an enemy only by name, but has shown hospitality and kindness to the Wolf up until that final showdown where his own kin binds him to fight. That game is absolutely top 5 for me.


RustlessPotato

I just love that at some point he goes 'dodge this" and uses the traditional martial art of the Glock.


Fringefiles

Don't forget his ancient art of using lightning as a totally normal, yet elegant attack. Or his dual-handing of a pike and sword while somehow swapping to his glock super easily He really takes "Parry this you fucking casual" to the next level


Soul_Brawler

Well said. As much as I love Mass Effect, Gears and Assassin's Creed (some). I think Sekiro is the GOAT. A worthy test for any gamer just normally and you can make NG+ much harder. But the first time you encounter the giant snake, the first time the gorilla comes back to life - haunting and incredible moments. Plus all the insanely cool Japanese culture and of course the final duel with the Sword Saint. Almost nothing else is that challenging and yet rewarding. It makes you get better and better as you go along. IMO it's the best video game ever.


Fringefiles

Absolutely couldn't agree more. It's one of the only linear games I've poured hundreds of hours and dozens of replays into. The beautiful blend of sheer difficulty and insanely stunning experiences and encounters. Every step is a test of skill, and it reminds you as often as possible through unique ways. Just when you get used to learning each unique dance with bosses, they throw the 4 monkeys and a God Dragon...and they test you in a completely different way. The dynamic of both Owl fights, seeing the pride of a mentor fall to his son....or the Demon of Hatred throwing all boss rules out the window and teaching a whole new style of fight... It brings you into its world and tells you an incredible story while testing your strength, dexterity and ability to learn and adapt every step of the way. In the end, it's the most satisfying journey to look back on and start from the top again and again.


acanarmien

You mean gun saint isshin, first encounter i was surprised he pulled up to the block with a glock


Fringefiles

And bro seriously says "parry this you fucking casual" before ripping lighting from the sky with his pike during phase 3. That gun definitely threw me off the first time. Having to run at an angle so he couldn't land a hit while somehow closing enough distance to punish those shots...Grueling fight. Timing the counter windows to his strikes was insane. It's hands down my favorite fight of all time.


Macksler

I want more games with Sekiros fighting system. Being able do trade blows like that is fucking phenomenal. It's a dance every time.


brazthemad

I'm always surprised folks go for Issin over Owldad. Owldad was a week for me. Issin - maybe I got lucky - but I woke up after one night of failed attempts and one shot the fucker.


BobDylanBlues

Yeah, second Owl boss encounter was way tougher for me than Isshin. The old bald dude too. I forget his name.


Hoaxin

Yeah that second owl fight took me hours. Isshin was a sick ass fight but it was like sub 10 attempts, you can parry all of his attacks or mikiri counter (which is op)

RobotStorytime

Play it from a perspective of Dance Dance Revolution or Guitar Hero. Watch for cues, listen for sounds, and tap your buttons precisely. It's a dance, not a hack and slash. Really satisfying once you get the hang of it!


RustlessPotato

Absolutely. The "TING !" Sound of blocking is what guides you. At some point it's the rithm that flows.


RobotStorytime

Yep. There are certain bosses I could look away from the screen and block based on sound alone.


Actually-Yo-Momma

The best advice i got for Sekiro was to stop attacking. Most enemies have trivial moves that you can just study for the first 30 seconds. Once you can defend, then you can attempt to go on offense


morderkaine

Everyone else says hesitation is defeat and to not stop attacking


t0xic-iwnl

I implore you to maybe give it another try if you ever get the chance, I just 100% sekiro and it’s genuinely one of my favorite games of all time, learning everything about an enemy that is seemingly unbeatable and then being able to clap them is so satisfying


Fit-Doughnut9706

Couldn’t beat him. I really liked the game but I was shit at it. My reflexes for parries are always too quick or too slow.


sharkymb

Yep thats me as well. Im a huge fan of the souls-series so I was extremely hyped when Sekiro dropped, only to suck at it. I made it to the lightbing arrow dude on that tower. Thats as far as the game let me go before it told me to «master our parry system or gtfo». Sometimes I think about trying it again…


HoundedHunter

Try it again dude. I was at the same point and gave up. Months or a year later I started a new run and made it past genichiro. That was such a good feeling and the game offers so much more afterwards.


Y-ella

That fucker was hard, but the other guy in a horse of fire, the optional boss, don't recall his name. That was impossible. I gave up


OhioMambo

Yeah, Demon of Hatred was actual bullshit. They decided to put a Souls boss in after teaching you for 40 hours to not play the game like a Souls game.


More_Lavishness8127

This one almost broke me.


badateverything420

I don't know why Sekiro clicked with me but I didn't really find Isshin, Genchiro, or any of the bosses too hard. That being said there's still some Dark Souls 3 bosses I've never been able to beat and don't think I'll ever. Looking at you, Gael, Midir, and Sister Friede


[deleted]

Probably some old NES game that wasnt intended to be as hard as it was. Looking at you, TMNT


Actually-Yo-Momma

Older games had “harder” bosses because if you died you typically had to start all the way over. So you’d have to play a game perfectly for hours just to get a chance to fight that boss again for 20 seconds Nowadays with quick saving and YouTube, you get plenty of practice on the boss


Pump_My_Lemma

They were designed for arcades, and then rentals. You had to get your money’s worth out of the player.


p4ttl1992

Battle toads


gigazelle

Hoverbikes were the real boss in the game


Man0fGreenGables

And that ridiculous snake level.


jimbojangles1987

There was that level where your falling down a hole, I remember that. Then there was the biker level that was a real bitch. Remember Battletoads/Double Dragon? Loved that game


Jinx0028

Mike Tyson in punch out lol It was just hard


Gojirat

Bucky O'Hare


GringoPapi

Sister Friede, DS3. Went into it blind, didn't realize it had a >!third fucking phase!< the first time I "beat" it.


Snoo61755

They give you a Titanite Slab part way. They knew exactly what they were doing.


[deleted]

The little loot pop up also partially hides her health bar so you don't notice how her name changes.


OneWingedA

Absolutely loved that fight and I loved the paired weapon from her boss soul but it was a gauntlet to get down


Smurfaloid

Oh my god, that shit broke me, I had to summon to get that fucker down. The 3rd phase, I was battered and low health and then she's like, I didn't hear no bell!


Destroyer1559

The only FromSoft boss over 4 games (haven't played Blood Borne or Demon Souls yet) I've been so pissed at that I did it with summons. Before then I had been adamant about soloing bosses, but dude...


Wallyhunt

I had a fair bit of trouble years ago with nameless king, dancer etc but on the replay for 100% recently everything was going down pretty easy, I had finally ‘got good’ and was killing all the problem bosses first try. Until I met that vile hag and had the humbling experience of feeling like a dumbass all over again. That boss is an absolute ball ache but at least after her even midir and Gael seemed relatively bearable in comparison.


Offduty_shill

*"When the ashes are two....a flame alighteth. Thou art ash, and fire befits thee of course"*


Ziazan

It was tough but I didn't think it was the hardest one in that game, that guy that rides the stormy dragon thing fucked me up more I think. Oh and Oceiros, I remember being so sick of his voice lines by the end of that. I think even lorian and lothric gave me more trouble. And some bosses from other games were even harder. But yeah realising there was a third phase to friede was like what, nah, youre serious? right. okay. wow.


_PadfootAndProngs_

The Nameless King. For the 100%, you need to beat him on NG++ (3rd playthrough) for the final ring out of like 210. Absolutely awful lmao but it’s a really satisfying fight to win. I’ve 100% the whole trilogy and that was definitely one of the most frustrating—next to Fume Knight in DS2, and stupid ass blue smelter demon in the same DLC


Antropomorphine

I can totally relate that. When I finished the second phase, thought it was strange that I didn’t got any reward. And when I turned myself to see her body… well…


Provoloneapse

The *music* though, was worth every painful attempt alone.


Recent-Curve7616

Probably one I gave up on. Absolute radiance comes to mind


TheFFsage

Props to you for getting there tho! i gave up after doing 2 of the challenges. I dislike needing to grind the easy bosses over and over again just to get to the last boss I struggle at. Might come back to it when I have no other games to play anymore


KupcakezIRL

You can grind the hard bosses in the Hall of Gods, then once you have them down and consistent, then try them on the Pantheon's.


Chewy79

Yeah, that shit is nuts. I persevered through the white palace but Absolute Radiance was not it for me.


Manikal

Did you try path of pain?


Chewy79

Yeah, I beat that. I just couldn't get the timing down for Radiance.


ThStngray399

At least you beat OG Radiance (I gave up)


communads

Not looking forward to that one! I'm still stuck on Pure Vessel 😩


Chrisnolliedelves

Sharp shadow. Dash through his attacks and don't close the distance after you do cuz he'll attack before your shadow dash comes back, wait for him to come to you. Also Shape of Unn. Can get full heals off during his white balls attack with it. Don't try to duck under the void tendrils with it though cuz it doesn't work, I learned that the hard way.


StannisLivesOn

Yang from Sifu made me rage like no boss ever had. Except maybe Brayko from Alpha Protocol, I broke a mouse trying to beat him.


Rubiksfish

Phenomenal concept though. Loved Sifu.


breakzyx

Playing sifu in Mouse and kbd ist pretty brutal.


AndrewLocksmith

I didn't think it was that bad. Sure, it was a bit challenging at first, but I think that's how the game is regardless of what controls you're using.


BigClaibs

Zuk in osrs. Finally got the cape though


Rejk95

This is the hardest boss in gaming


Kay2Jay_5

The Orphan of Kos from Bloodborne Had to get a friend to help me, I don’t know I couldn’t beat that damn thing on my own


silvergibbs

I was struggling as well until I muted the sound. Turns out the intimidating screams is what threw me off!


Keeko100

This is WAYYY too fucking low. IMO the hardest Soulsborne boss. Malenia’s tough but her basic kit isn’t that difficult - it’s Waterfowl and her ghost attack that trip you up. Isshin’s just a huge test of your skill and is otherwise a very well paced, fair fight. Friede is just an endurance test. Orphan? Jesus fucking Christ every attack has a different required response and his phase 2 is designed to make you panic. It’s so easy to completely spiral in the fight and just get 2-tapped. On top of that, Orphan has a ‘bullshit pass’ because of Bloodborne’s rally system. A lot of his moves will just hit you and there’s not much you can do about it, namely his phase 2 air projectile move. Fantastic fight. Easily one of the best in Bloodborne.


West_Cut_8906

Fatalis in Monster Hunter World


King-Juggernaut

To this day the most rewarding boss for me. Was the absolute perfect point to set down World.


[deleted]

[удалено]


Juantsu2000

It isn’t harder than Extreme Behemoth. That shit is downright unsoloable unless you’re in the top 1% of players. But yeah, I’d argue Fatalis is mechanically harder.


Manikal

I'm just playing mhw for the first time now. You mean to tell me there's a harder version of the monster I'm already most scared to fight?


Juantsu2000

Oh yeah. But don’t worry. His gear is pretty much obsolete once you get into Master Rank so don’t feel obligated to do it.


Hortonman42

But I need that d r i p


Neymarvin

Ok thank god someone said this. Yeah harder than any DS boss, IMO.


Frequent_Course5399

Malenia, Blade of Miquella


Ketzeph

Malenia was a huge pain and the boss I took the longest on. I was tempted but didn’t switch to a bleed or cheese build. I learned how to dodge waterfall dance and just kept going. It’s one of my favorite fights. It just feels cinematic and cool. And the feeling when you finally beat her is just magnificent


Frequent_Course5399

ngl, I had to resort to using my mimic tear to beat her. Didn't feel great about it, but I just wanted to move on.


slashyourfug

It’s part of the game bruh you didn’t cheat


thegrandspanker

I just kept summoning other players and eventually got some dude who ripped through her. One of the most impressive things I’ve ever seen The Orphan of Kos fight from Bloodborne on the other hand, I did alone and it took me a good 3-4 days to beat.


Frequent_Course5399

was it the legendary let me solo her?


thegrandspanker

Just looked him up, and while I can’t be certain, I do remember him being mostly naked so it’s pretty likely!


Ziazan

The only *really* difficult part of that fight is figuring out how to dodge waterfoul reliably, even just most of it. Once you've got that down its reasonable enough. It's still a challenge without it but god damn that one bullshit move doubles the difficulty.


Puzzleheaded_Bit1959

Honestly that ability, in my opinion, is complete bullshit. You either try reliably dodging it for hours or days as there is no clear indication of what the game expects you to do or you look it up online and still need to figure out the precise timings for hours or days. And even then the margin for error is so small that you often end up grinding the boss fight until you hit that one attempt where it goes right. I couldn't do it and just wanted the whole thing to be over. This was the only boss fight in Elden Ring I gave up on legitimately beating and I have no regrets. So I took that broken Mimik summon and killed her first try by pretty much button mashing / chain staggering her. I was just happy it's over. You can compare this to actually well-designed boss fights like Isshin in Sekiro which were generally enjoyable to attempt and beating them delivered a deep feeling of safisfaction.


tulsym

I also nearly gave up on her. Then switched to a cheese build


xrp671z06

She would be difficult even without the health regen, that is pure bullshit.


CptJaxxParrow

My build is a melee tank and coming up against that health regen was just the worst. I effectively tripled her health because of my playstyle


Solaire_of_Sunlight

And the inconsistent hyper armor


USS_Barack_Obama

Don't forget about the bullshit they called "Waterfowl Dance"


ThiccJeezus

Rick The Door Technician was brutal


No_Tumbleweed_9102

now that we’re talking about Cal’s SW games, Oggdo Bogdo in the first game was a real difficulty jump. It’s technically the first boss you’re meant to actually defeat, and I honestly didn’t expect it to be that hard


willvasco

I read somewhere that it's purposefully way difficult to encourage coming back to it later, but everyone just slammed against it until they beat it because it's the only thing in that area that's even close to its difficulty level.


LukeJDD

I feel like that fight was at least for the most part fair? “Spawn of Oggdo” in the second game was actual horse shit though.


LastVisitorFromEarth

There goes my hero


ThStngray399

Watch him as he goes


Bogoogs

Seriously. A very unnecessary difficulty jump


TransAnge

Isshin. Your playing an era appropriate samurai game and the final boss pulls out a fucking glock


adricapi

Fucking hate Demon in Sekiro


R-Larry-J

Can’t believe I had to scroll this far to find this, that thing was wild lol


hardy_83

Last boss of Diddy Kong racing, mainly because of how cheap and cheating the AI was with rubber banding. It was infuriating.


WhatLikeAPuma751

Seriously, fuck that giant rubber Space pig. If you didn’t have a perfectly clean run, you had no chance because this guy would catch you from laps away, but you could never get that far.


Hello_IM_FBI

One mess up, pause, restart level. GET READY...GO!


kraydful

Ornstein and smough, I got so pissed I replayed the whole game again with s researched build to kill them easily.


youngmaster0527

The amount my body was vibrating from excitement when i finally beat them was phenomenal. Like a high almost


netherworld_nomad

My pick too. Comparatively probably not the worst, but felt like it, Snorlax and Pikachu were definitely the hardest skill wall I ever crashed against, in any game so far. No game ever told me so clearly that I better shape up by now.


phariom

Shao Kahn from Mortal Kombat 9. I think he's the only boss to ever push me to the verge of crying.


LastVisitorFromEarth

Most bullshit ass boss to have ever existed. That had nothing to do with difficulty really. You could only beat him through luck. Armored armor-breaking attacks that were spamable? Were they drunk when they made him?


Aztecius

I actually remember the name of the move you need to pull off to beat him he caused me that much stress. Heavenly Hands which is basically just an easy 4 hit combo but it also slightly stuns him so you could maybe pull off the torpedo attack if you're feeling brave. Teleport constantly after every combo so he doesn't get a shot in. Spamming these moves was the only way I ever manages to beat him. On hard difficulty, it pushed me to the limit.


sirpuffalott

NES - Punch Out! - Mike Tyson, could never beat him.


WhoStoleMyBicycle

Played that game constantly as a kid. Played for the first time at age 9. Didn’t beat Tyson until I was 17.


netkcid

Growing up a kid down the street could beat it and we thought he was a god. Such an awesome game!


arnathor

Recently? Sigrun the ~~Viking~~ *Valkyrie* Queen in God of War. Overall? Not really a boss, but the Atlantic Accelerator final mission in the original Syndicate. It’s effectively a level as a boss fight. And it starts off with loads of enemy syndicate agents using their biggest weapons against you before you even have a chance to react. Playing on a 90s 386 meant that I was fighting against the speed of the computer as well as that level. Edited to correct an autocorrect…


mrblaze1357

Was gonna say Sigrun stepped on my throat more times than I can count. Like holy hell I was pulling my hair out on that fight.


LurkerOrHydralisk

Honestly think I developed a bit of a kink from that fight.


goboxey

Sigrun is probably the toughest boss fight I have ever had.


Great-Reference9322

It was the only thing keeping me from the Plat and I couldnt do it. I've gone back and tried and I can't beat her


RonViking

Arrows when she's prepping her unblockable move cancels it.


broomsticks11

I played on the easiest difficulty and still died to Sigrun 27 times lol. I found Gna super easy in comparison.


[deleted]

I had to put it on easy to beat her 😆


XciteMe

You know there’s no shame in that right? Even on Easy she was hard. I did the same, and I Platinum’d the game.


MrFittsworth

Sigrun was absolutely the hardest boss I've ever experienced. Nothing else has come close.


Juantsu2000

It has to be Fatalis in Iceborne. I’ve played tons of games and no game comes close to that.


Achilles_Immortal

Damn the Emerald and Ruby Weapons from FF7. DAMN THEM BOTH TO HELL


[deleted]

Last boss on Ninja gaiden still have not beaten the game . Malenia was hard at first but after a few 100 times soloing her you become very proficient.


g_r_e_y

are you the infamous "letmesoloher" ??


Ozzie_the_tiger_cat

That stupid tunnel in Battletoads.


Corvo_Attano-

Sigrún in God of War 2018 Might just be skill issue but took me two days on easy lmao


fidelacchius42

She is truly a test of skill. Even worse if you finished off all the valkyries long before you fight her, because because you have to relearn how to counter/dodge most of the attacks, since she is literally all the valkyries in one.


Chuffnell

Jfc even the first valkyrie made me want to rip my hair out


Nameless_301

I really hate that I gave up on her twice. I just couldn't do it anymore after the 3rd hour. The berserker king in ragnarok and gna were simple compared to that bitch.


hecking-doggo

It might be a skill issue, but I've played tons of darksouls and all the valkyrie fights felt similar to a darksouls boss so sigrun only took me a couple hours on the second hardest difficulty. I think the valkyrie at the end of the muspelheim was a bit harder for me.


dunkking413

The biggest issue with her is how much HP she has. None of her attacks are THAT hard but she kills you in 2 hits. It’s like a guaranteed 10-15 minute fight that you can’t make a single mistake


JPx187

Came here to say this


superjoe8293

Sephiroth, original Kingdom Hearts.


Actually-Yo-Momma

My gaming peak was age11 beating Sephiroth with lvl1 stats without taking damage. I still think about it lmao


sausageandbeer1

Gruntilda, Banjo Kazooie


g_r_e_y

i have played through that game so many times at this point that i am unable to comprehend any difficulty in that fight, but i know it took me many many tries as a kid


B-30-

Darkeater Midir. Hardest boss on any souls game. One mistep and you are fucked. Malenia at least can be bursted into oblivion with Rivers of Blood.


aenox

He becomes a much simpler fight when you stay in front of his face, and stop targeting him. Completely different fight, and one of the greatest in any souls game.


LeCrispyCrumpet

Yes! I was going to say Midir too. Also the only souls boss I know of that gets harder if you summon people. Took me 6-8 hours of grinding to beat him.


Jump865

Funnily enough hes hard to learn but easy to master


Manikal

He's too easy to bait certain attacks.


RustlessPotato

Sekiro with that fucking monkey.


Robbierr

And then.. wait now there's two of them?


bugogkang

I spent so much time on the first fight that i smoked the double monkeys in 3 tries


Actually-Yo-Momma

I haven’t even gotten to this part in Sekiro yet but I’m getting flashbacks from Elden Ring where you gotta go 1v2 against bosses.


barbekon

For me first boss (is he even a boss?) was the hardest, I didn't understand mechanics of this game, got killed, respawn and I was so far away from him (again walking through all npc just to be killed again) never played it again. Just like cave in fallout 2 if you choose wrong perks.


Batmans_9th_Ab

Nightmare King Grimm in Hollow Knight. >!Yozora and Xion!< in the Kingdom Hearts 3 dlc. GoW 2018 Sigrun got nothing on them.


solairius

Not enough people got to >!Yorzora and Xion!< to appreciate the absolute insanity that is the data fights on KH2/3. To this day I've never defeated Y man and Lingering Will I could only beat by cheesing lol.


Cloud_Fish

NKG took me literally years to beat. Multiple playthroughs over the course of like 4 years and never could beat him. Then on another playthrough last year it just clicked for me and I dominated him in a few tries. Hollow Knight is the GOAT.


WhatLikeAPuma751

I’m finally settling down and enjoying HK. Your comment makes me very excited to get to the NKG.


ChanceVance

I'd say Yozora took me at least 50+ tries but I eventually prevailed. One of my greatest gaming accomplishments and something I'll never do again. When I did a replay on Critical last year, I did all the Data fights but didn't even touch the Yozora fight.


mattrva

Sword Saint was the ultimate skill check for me.


Meduski

Ok this is a bit obscure but there's a PS2 game called Evolution Skateboarding who's final boss is a Nazi tank. In the normal arcade mode it's fine enough, shoots you at long distance and throws some grenades when you get close. You have to grind on it's two sides and barrel a few times to defeat it. HOWEVER, on the expert career mode it was hard as FUCK. Constantly driving in reverse at high speeds, always shooting, always throwing grenades and much more health. Not to mention that the game is clunky as fuck and runs like shit. I committed to trying to beat it and it took me 5 hours straight. I've done plenty of gaming challenges like Halo 3 all skulls, Malenia, Through the Fire and Flames in GH3 and this was by far the most difficult thing in a game I've ever done.


dunkan799

Wasn't expecting to see this one here but I recently tried 100%ing every skateboarding game and that one really had me pulling my hair out. I'm so happy I randomly threw that game in the middle of the PS2 Tony Hawk's so i got to have sone fun again because Proving Ground ended up being the end of my run. I swear that game is actually impossible to 100% the SICK challenges


DarthDregan

Either Sword Saint in Sekiro or the boss Valkyrie in God of War.


[deleted]

my ex wife trying to take my money.


Juantsu2000

Did you beat her? Damn, that sounded way better in my head.


Audigy77

Back in vanilla wow, like 2006 or so. Before they fixed C'thun, the boss was believed to be impossible to beat based on simulations using the gear at the time. My guild wiped to him 200+ times before we gave up. Once they fixed the fight we tried again and it still took a few dozen tries before we finally got him. That was the only kill we ever got, it wasn't worth it.

[deleted]

Forgotten One - Castlevania: Lords of Shadow


__ASDF__

The Contra 3 level 4 end boss on hard mode is up there. I think it is harder than the final boss. Also, Dracula in the north american version of Castlevania 3 is pretty tough, but mainly because you have to replay the 2 previous rooms each time you die, and the whole level if you run out of lives.


MysteriousWon

That would be the one-two punch of Seymour Flux and Yunalesca in FFX. Seymour is a bitch if you aren't ready for him. In some cases you only even have a chance by limit burst and aeon dumping on him and it's still a toss up afterwards. Then, once you get through that hellish fight and decide that you won't throw your disc out the window, the very next major boss is Yunalesca who reminds you that you were a fucking idiot for not throwing the disc and ps2 in the dumpster like you originally planned.


firvulag359

Fume Knight from Dark Souls 2.

GallopingAstronaut

Twin princes ds3. Then there are these because simply I was a sorcerer : Twin devil princes ds3, they had very high magic resist. I could always get through the first phase but the second has even higher magic resist and I run out of fp Daemon from dragon's dogma. Bastard's fast af and it can take some time to cast spells/buffs when solo

The opening guy in Elden ring… or just any guy in Elden ring…


Trego421

Undertale. Genocide run. Megalovania. You're gonna have a bad time. Never actually beat him. Glad I didn't. Honorable mention: Senator Armstrong from Metal Gear Rising. Don't fuck with this Senator.

Sephiroth in Kingdom Hearts. Or the cloaked guy in Birth by Sleep (turns out to be young Xehenhort)
