The 10 *WORST* Kingdom Hearts Boss Battles! 

Thing that aggervates me the most is when a boss only have a small window to actually damage them. Ursula in Rechain of memories is the worst because you'll have to start reloading your cards so the waiting period is even longer

My traumatic fight is Data Larxene from KH2. She literally just spams thunder until you die, and due to the small battlefield, it's basically impossible to avoid it.

"I've never been a fan of bosses being able to heal themselves" Logically, it makes sense... We have access to restorative moves and items, so bosses doing the same can be interesting and catch you off guard... It's just HOW it's implemented that's the issue. Having ways to prevent it would make it interesting. That YX fight at the end of DDD.... yeah screw that fight

What I hate in a boss battle are when the boss attacks you and there is no way to impossible to dodge or not take damage, or when the boss is charging up something and they keep you away from attacking them like Sephiroth's heartless angel move.

I heavily appreciate the DIO references with Young Xehanort here But yeah, his fights in DDD and especially in BBS are just the absolute worst

To be fair in regards to the young xehanort fight it technically only returns him back to only four health bars, as apposed to him having his full health in the very beginning if you fail to beat the clock before it resets

It gave me anxiety watching the Ursula fight and Sora attacking her from the front

I literally accidentally beat MF as Terra. He was invisible and I guess I hit him enough times but I thought for like 10 seconds that he killed me because I was so used to dying.

The way you described the Grim Reaper fight is actually the reason why it's one of my favorites, there is a certain rush I feel while managing MP and running around for the medals while dodging its attacks, it is a very fun fight that keeps you on your toes all the time, but still not being too hard, being quite mindless on Standard but decently challenging on Critical

Not gonna lie. I like the Grim Reaper fight 😬

fun fact about mysterious figure: during playtesting, testers said it was too tough, and nomura allegedly gave him an extra HP bar in response

The amount of despair and PTSD I feel when I hear Dark Impetus play as some hooded dude twirling around blue lightsabers is pretty crazy.

Fun memory about Ruler of the Sky: I tried playing it in multiplayer as Demyx. The windup on the first hit of Demyx's basic combo is so slow that it's impossible to hit him.

Fun fact about Mysterious Figure, he was actually conceived and developed for the original Japanese non-fm release, but was cut due to the devs thinking he was an unfair fight. He would later be implemented due to story implications in the American release and later the Japanese Final Mix release of Birth by Sleep.

I respected your takes but saying that data luxord is bad because you have to wait for openings is the most ridiculous thing i've ever heard. Idk if you played crit/lvl 1 crit but that applies for every data fight in kh3, and the fights are masterpieces because of it. The game forces you to pay attention and learn defense instead of mashing attack like most players are used to.

I don't know if someone else had personal difficulty with this one, but I subjectively had a lot of trouble fighting Captain Hook in BBS. I underestimated him and I instantly regretted it lol

With how many fire boss fights we get in KH though, it's impressive that there aren't more horrible fights or fights that are worse than the ones you listed.

I never really had a problem with Young Xehanort in DDD. Mechanically speaking, the clock that resets the battle if you don't destroy it is just your standard time limit death, no different from Demyx. It just has neat flavour text and doesn't send you to the Game Over screen.

I love Data Luxord in KH3. Really changes the pace of the fight, which helps a lot with the variety!

I remember the ruler of the sky genuinely hurting my hands to play against on DS cause of having to hold the glide button and move the dpad, also this isn't a boss battle but a mission in 358days where you need to clear SIX bosses , 2 of which I believe are mentioned already, in a very tight time limit.

I have an idea for a video, you know how each secret boss had theories on who they might be ? I think a video covering the history of each mysterious secret boss and the speculations around him would be fun.

tbh 3D xehanort wasnt that bad considering that every time that he does rewind time, he has considerably less and less hp, so even if you couldnt stop it in time, it didnt extend the length of the fight TOO much.

Been watching you since your KH 2 final mix let's play - this video is giving me throwbacks to the Golden Keyblade. Thanks for still making videos! 🥳

Forgot to mention with the Julius fight that if he hits you with charged fists, you lose a command bar.

Vanitas Remnant has traumatized me so many times I now have PTSD whenever I look at an Oreo

Few of these are a bit incorect. For example YX in DDD only get's his full health back if you fail to do enough damage to the clock. Also in the Luxord fight you don't have to run towards the cards. You can use shootlock to slow down time and then airstep to the right one. I feel like few of these you just made hard for yourself lol.

Watching this video made me realize that the bosses in Days were pretty hit-or-miss. Leechgrave and the Ruler were mentioned but the Antlion only allowed toy amall windows of attacks after which you had to hit back its own explosives when it rose out of the sand, and getting those explosives to go his way wasn't easy.

Fun fact: Mysterious Figure is the only boss battle that had to be nerfed for future releases. In the original PSP release, getting caught in his Collision Magnet was an automatic game over, since he’d follow up with an attack before the stun animation was finished. In the console releases, Collision Magnet became escapable with air dash. Not that it made much of a difference.

The phrase "Dance water Dance!" Still haunts me. To this day. I really despise that boss fight.

My personal worst was the phantom. Between the weak point gimmick and the doom clock, I always dreaded facing him to get the stop spell upgrade.

I feel like Skyward doesn't know that Data Luxord (KHIII) does have openings after pretty much all of his attacks.

0:37 I screamed way louder when I finally beat that man :’D Woke up the whole house ^. ^’

Not having Terranort or Vanitas on here feels criminal, but seeing Leechgrave and Ruler of the Sky being so high is justified in my book

Regular Demyx was a big enough pain in the ass. I'm glad I haven't tried DATA Demyx.

Everytime I think about playing Days again, I remember this Ruler of the sky battle and give up.

9:25 From what I remembered from your previous version of this list, you had Trickmasters, Dustflier, Darkside & Zexion on there, since you did bring up Ursula, Spellican, Grim Reaper, Leechgrave & Ruler of the Sky already on that video as well.

Ruler of the Sky for me....... it was such a slog I quit the fight, quit the game and haven't bothered to go back and try again.

Julius legit gave me ptsd as a kid, i thought balloon sucked so i never used it. Oh boy i made it harder.

So 358/2 Days. There’s a particular mission in Mission Mode that’s essentially a Boss Rush for every Heartless you’ve faced relatively up to now. After clearing the last boss, you could exfill…or there’s a special boss you gotta go find. You get to the train station, and you are met with the most BS boss fight in the entire game. The Crimson Wyvern. This boss fight was a paaaaiin, with such a limited field of movement, it can summon a meteor shower that can rip 1/4 your health as damage per hit. It’s body slam can cause Silence, negating all Magic(who’s system was either busted or garbage, depending on the spell or level of the spell), it’s tail slap can cause Confusion, inverting your controls for a spell, or THE WORST AFFLICTION EVER in game, Weighted/ over-encumbered, with not only slows you down, but also limits your jump and gliding ability, in an already limited amount of space. I tried so hard to fight it…I noped after the 6th attempt. To this day I never defeated it, that thing is so INFURIATING!

10:08 you dont have to destroy the tentacles I remember beating on the grave until I beat it but you have to be careful of the thing inside it because it will one tap if you get swipped lol

having a list like this and not including the secret boss from 358 with a million HP that spends most of the fight flying away is just criminal

I'm glad that both data demxy and data luxord were on this list (I hate fighting them) however re:mind luxord I actually preferred fighting compared to kh2 because in kh2 the ENTIRE fight revolves around timing which as a child I didn't have even to this day I have trouble with his DM but in remind it felt like an actual fight that had some timing parts also it's the only re:mind data fight I beat on my first try

I remember hating the fight with mysterious figure primarily because he could take away your ability to attack. I also remember him using this one attack where he just kept summoning clones of himself to attack while his real body casually strolled behind them, like come on man.

I had a glittch that happened to me against spellican , during the fight he just teleported under the arena where I could not hit him . And then I died .

I hated learning the grim reaper fight with no help cause as a kid I didnt understand the mechanic at all intuitively but after I figured it out it was ended up being one of my favorites

The worst for me are two bosses: Data Riku and Data Saix, from KH3. Data Riku's entire gimmick is just filling the screen with AOE, turning the boss into a game of "find the one pixel of safe ground." But both him AND Data Saix have far too many particle effects. I have vision problems and so the sheer amount of explosions and particles means I can't actually SEE anything going on. The fact that mechanically they're the same dance fight we've had since KH2 just means I can't see anything AND they aren't fun to fight. Say what you will about Mysterious Figure, but at least he had comedy value.

i was pissed off when YX went back in time, but at the same time, IT IS SO COOL. Dude literally Bites The Dust you and I love it. He did it only one time to me, and that's enough to make me love the boss fight

Terras final boss in BBS and the final boss for the final route in bbs were the worst. You basically have to rely on deflecting, because attacking as you combo’d to death. Took me ages

How bout “top ten pure fun KH bosses” where it’s just about how well the mechanics are incorporated, or how a boss utilized a certain gimmick to enhance the experience, or how epic the level design is, etc

Mysterious Figure is really cool but holy shit the devs were losing their minds making him. Giving him orbs that shoot the player from all directions literally impossible to block(unless your Aqua) Giving him a doom attack that gives u 5 seconds (FAST SECONDS MIND YOU) to mash out that gradually starts at a lower time the more u get hit Rewinding and punishing u for attacking Back in the psp version version the rope attack usually lead to u dying(iykyk) The invisibility making him impossible to lock on to His ai will instantly use invisibility if u try to d link He can interrupt and cancel his attacks in RESPONSE to your block Seriously wtf were they thinking

I also hated the keeper of the sky boss fight in 358 along with leech grave cause those two alone gave me all sorts of trouble

I don’t know why I hadn’t subscribed to your channel. I jut did. Greetings!

You know what makes Ruler of the Sky worse? Your strongest physical keyblade at that point in the game only has a 2-hit aerial combo, and the second attack in that combo is the dive that's easy to miss as he just flies away.😅😤

I've never been more stressed out fighting a boss fight like Ursula before 😭

While I've never done it, I imagine the Unknown in BBS Final Mix is a pain because it constantly attacks you.

I achieved Platinum on BBS yesterday on Critical Mode, and trust me. I will NEVER do that Mysterious Figure fight again. NEVER!

I love what Joshscorcher says about Ruler of the Sky. "Long and boring boss is LOOOOOOOOOOOOOONG and boring"

The Mysterious Figure was very annoying to beat. It took me 2 days just to try and beat him with Aqua and Ventus and 3 days with Terra due to some limitations he has like the way he dodges is different compared to Aqua and Ventus so I had to adjust my way in fighting this guy. And after beating him, I thought I hope he doesn't show up again. Then Dream Drop Distance. I was fighting Young Xehanort and notice his weapon and the color and he is able to control time. And the first thing that came in my mind was : OH $#@%! NOT YOU AGAIN! There is also that Vanitis Remnant (I think that is what he is called) who was also in Birth By Sleep. When you fight him, he has only one health bar which I thought was odd and found out magic doesn't hurt him and you have to beat him with only physical attacks, the problem with that is that he takes very little damage that way so it takes a long time to beat him and it is another fight that you also have to dodge a lot. You also can't uses cure in this fight because he copys you and heals himself so have to use healing items instead or some other way to heal yourself. Shotlocks can't hurt him either, but they are useful in avoiding some damage if you are having problems dodging his attacks like when he encases himself in a black orb and sends shadow clones of himself to attack you. And the funny thing is that you have to beat him if you want to fight the Mysterious Figure (Young Xehanort) later on.

Atlantica in KH1 I actually liked. The Grim Reaper in KH2 wasn't that bad to me. The Leechgrave is definitely a bad boss to fight. So annoying.

Thank you for reminding my of Data Luxord of the Re:Mind kind, and all the pain thag came with that fight.

That 2nd Ursula fight was the bane of my existence when I first played that game.

Just seeing Ruler of the Skies, I became angry, frustrated, and felt like my time had been wasted for no good reason. Thanks for a great list!

Before I say anything, I love you’re content and I enjoyed the video 💗 Imma be real, I think putting Grim Reaper and Data Luxord on the same list as Leechgrave is kinda crazy. Like the days bosses are a whole new breed of terribly designed and miserable to do. At least Grim Reaper staggers and can realistically be beaten in a timely manner if you’re careful (unlike every days boss).

You are meant to use air step during Luxord's DM. I find it the absolute easiest and least frustrating of the battles. You have just enough time to think before you are punished as opposed to the non-stop aggression of other fights, and it's more then just guard > counter to open up the opponent. I still love the other fights (aside from Data Riku) but Luxord is definitely the most fun for me.

I'd swap Grim Reaper with Anti-Black Coat, personally. The Grim Reaper isn't a great fight, but I can think of worse.

I think a Top 10 Worlds that Almost made it into a KH Game would be a cool list, I remember hearing from the creator of Gargoyles that NYC and the gargoyles characters were suppose to be in the original Game. Can only imagine what the music would’ve been like.

Mysterious figure single handedly broke my Square button back on the 2.5 collection, having that platinum trophy for BBS is worth it and i got it again in the 1.5+2.5 collection

Ddd is my favorite game in the franchise. And while I do agree he’s easy due to the fact you can kill him if you throw a birthday party. If you let’s say don’t use the balloon spell and instead wanna fight him head on. He would be considered one of the hardest bosses in the history of kingdom hearts

For me personally, the hardest boss fight is the optional one in days where you have to fight seven giant heartless. I don't remember that secret dragon's name but the trauma I have from it and the satisfaction of screaming at the top of my lungs when I beat it. The worst part was that one of my failed attempts came from accidentally running into the exit that leads underground causing the boss to regain all its health lmao

I haven't played so much of the series, but I hated the final Riku fight in KH1. It wasn't hard, but it was lame as hell... If I tried to hit 3 times, he would do his stupid rage-swinging and hit me. So I finished this whole fight using 2 hits and then jump over him...

There’s a glitch I found out when fighting Demyx yesterday (for the first time. I did not have fun) After the first wave of water clones and when you defeat them all. If you hit him with like 5 empty ground hits (not fully finishing a combo) then do a full air combo. then get one full ground combo off. He will start doing his move that activates Sora’s reaction command. I don’t have the full recording but I have a 30 second clip on my switch of him just repeatedly doing it over and over again. I found this out after I lost 10 times the previous day then like 6 yesterday. Also you can’t use any drive forms

The mole im dream drop drove me nuts having to fight it 2 times and it just kept running away from me That an xigbar as a kid i literally couldn't beat his move where youre in a small platform and have to run in circles

Honestly if I had to chose a boss from KH2, in the second visit of the worlds, I'd go with The Experiment instead of The Grim Reaper... The Experiment Fight is scary to me, especially on LV1, oh my god xD Other than that, great list !

I still remember as a kid playing kh2 on critical and xaldin and xigbar were the biggest pain

For data Demyx, you gotta use blizzard on the clones so they'll turn into the notes which give the wild dance reaction.

I remember when 100%ing birth by sleep, I beat unknown (young xehanort) with all 3 characters on psp where when you get caught by his tether you can't dodge out of his attack. Took like 90-something tries but I perservered.

10:00 I remember getting walled here so I went and did every available challenge to 3 sigils and got all the mission crowns I could. Did a whole bunch of leveling. Used a str based blade and tanked hit after hit, used my limit attack to shred that mother clucker. Also, Grimm reaper 2 is a really good fight if you set it up. Shortcut thunder and reflect, give doland thunder and only let jack use his throwing knives. Thunder spam while jack throw knives, making it drop mp orbs to replenish us. After the dm go matter form and just spam Thunder in a circle around the reaper, it will go down no problem

As someone who grew up playing BBS, i feel validated that others also find the mysterious stranger hard

1: Phantom or Ursula COM: Riku 4 2: Genie Jafar or Roxas 358: Leech Grave or Ruller of the Sky BBS: Mysterious Figure (Not a secret boss imo, this is an exabition match) Coded: Data Darkside/Anti-Soras DDD: Orb Ansem or Spellican 3: Lump of Horror

I love Julius. Wish they'd use more unknown characters, like old cartoons or the comics. That's why i also love the three musketeers world

Yup, this list is pretty on point. I wouldn’t put ruler of the skies quite that high, maybe the secret boss from days.

I will not tolerate grim reaper slander lol. Especially when Vanitas Remnant didn’t make the list 😭

I don't know what's going on, but RU-vid keeps unsubscribing me from your channel, this is the 3rd time I've subbed to you.

Honestly, I thought that the final battle with Marluxia (Re: Chain of Memories) was a difficult boss fight. Not only it's a card game, but he also has this annoying ability to scatter all your cards around the arena, and you scramble to get them back to respond to his one-shot attack.

Have you forgotten Dustflulier from 358/2 days? He has a shit ton of health, a high Defense, attacks that are almost instanta kill. The best way to beat him is to follow a specific pattern that will bore you to death causing you to slip up and die and have to start all over again.

The ruler of the sky fight is the bane of my existence. It is so slow and when it goes berserk he does a lot of damage. It's still hard for me to believe that I beat this guy on the hardest difficulty. Took forever but I did it

I actually quite like the Data Luxord fight in 3. It's a pretty fitting fight for Luxord. Also my least favorite fight in the series is the MCP fight. The MCP fight makes me want to succumb to darkness

Genie Jafar. All versions. Run to the smackable spot, stay there, get moved away, repeat.

To be fair, I didn’t have much trouble with Data Demyx in KH2FM. I beat the guy on my fifth try. The key in this fight is to get Demyx into a corner of the arena and use blizzard on the water forms to get the reaction command. I only use Wisdom for for the 99 clones at the very end of the fight.

Please do your top 10 best boss fights in KH next bc its only right that since you started with the hardest ans worst boss fights that you do the best boss fights Skyward also I really love your KH3 story rewrite vid it makes the story so much better compared to the we actually got.

My nightmares are with Terranort (Xehanort in terra's body) at the end of terra's campaign of BBS, but im still discovering the kingdom hearts games so that may change.

Yeah, while i wasnt expecting a lot of what was on this list, Mysterious Figure (convenient initials there) was the one i thought would be first. Or at least on the list somewhere. A lot of the bosses, i just never really had so much issue with. I played by Ursula so much that it never occurred to me she might be here. Need to replay Days. Finally, as for Julius, i got a very strong impression his fight was based off the BBS Mysterious Figure fight.

If we're going by normal playthrough bosses without doing the extra stuff, then Ursula from KH1. I don't know what it is with her, but even as an adult playing through casually, I had such a hard time.

There isn’t one game that has all the kingdom heart games ever to be released is there? I would love to play them all over again.

My most hated boss fight was Ansen the wise from Dream Drop Distance, because during the battle he basically decides that you lose

Data Luxord from KH2 makes me want to cry. I hate the move where you have to get circles on every slot in the command deck fast enough. I started out pretty bad at the gambler mechanics but his other moves felt doable. I haven't even attempted Data Luxord from KH3. Cherbourg from KH1 gave me so much trouble and then realizing I needed fully upgraded Aero to win felt cheap. It also made the rest of the game feel easier in comparison because I already had fully upgraded Aero.

As someone who made a 100% guide for Kingdom Hearts 358/2 Days...I absolutely agree on Leechgrave and Ruler of the Sky.

I mute my TV every time I play a song mission in Atlantica in KH2

BBS was my last game in the series to platinum due to Mysterious Figure? Fruitball and ice cream. Every other game, including MoM, was already platimumed

Absolutely Data Demyx and Luxord KH2. Both unfortunately in my battles just rely heavily to luck with those mini games.
