Top Ten Hardest Undertale Bosses
The Top Ten
I think sans is the hardest because when he sends you through those attacks and it blacks out so you have to remember what the attack was.
I haven't fought him, but I've seen videos, and he is EXTREMELY HARD!
The battle was painful for my mental health. I swear I could hear gaster blasters in my sleep until I beat him.
Though you don't have to fight sans, he is extremely hard. Everyone should know this.
Basically the final boss of just shapes and beats but 2x as hard. His attacks are fast and to the point.
Although his battle does SAVE, no amount of skill can let you NOT DIE on this guy. To be fair, I haven't attempted the genocide route, so I haven't battled Undyne the Undying or Sans, but he is much harder than Asriel, as his battle SAVES even more.
Other boses are challenging but you can memorize there attack patterns over many repeats you can do that with flowey sure but I don't have the reflexes. I remember coming out of the asgore fight and found him one of the easiest bosses but then flowey came and killed me almost instantly over and over I haven't fought sans or Asriel but I can't see them coming close to the difficulty of flow since I can't fight him for more then 20 seconds
He’s not too hard to me asgore was way harder like I only died once in this fight
asriel the god of hyper death is very hard but thr attacks are easier basicly like a normal asgore
Only boss I died to. (not counting sans or omega flowey.) LIKE, COME ON. IN HIS TRUE FORM, HIS ATTACKS ARE INSANE. But the sad part is... when... he begs for you to let him win. Then he does that INSANE attacks where you barely survive.
Didn't want to vote for this, but you cannot die during this fight. Froggit is easier
How is this fight hard? You can't even die in it!
I spent almost 2 entire days trying to kill her. I was so happy when I could finally beat her.
hard please I wanna cry I'm gonna make her into fish fingers soon if she keeps this up
I actually beat Sans under TWO tries and I beat Undyne the Undying under SEVEN tries
Undyne is incredibly hard. She is surpassed only by a fat-*** skeleton.
Asgore took me a while to beat but after that, I got his attacks in my head easier.
Good god. On my first playthrough, I got through Undyne in 2 tries, The Dummy in 1, and Muffet in 4. Asgore took me 27. Asgore is HARD.
Asgore is like an exam you didn't study for.
Actually, the fight is not that hard of you eat the pie.
How do people get past this sometimes first try although sans is hard I survive longer against him then undyne
Undyne is just hard no matter if its genocide undyne or regular
This is way harder than any of the above apart from sans.
its hard to get past undyne
on the essay question, I just said, "lol he sucks" and then he said, "perfect! you get a gold star!".
Only person I died to in pacifist run through (and that was my first time through)
Along with Undyne, the one of three bosses I died two on my last playthrough.
The background music is good but he is challenging as hell!
Unless you have a Spider Donut and/or Spider Cider from the Ruins, Muffet's pet is super good at DESTROYING you.
Muffet got my vote. The way her attacks come at you. Eat a spider donut in front of her to skip the battle or if you already bought a spider donut in the ruins, in the dinner phase a spider will bring up a note and the battle will end. Struggle or pay to slow her attacks. Took me many tries.
I eventually just gave up and started selling a bunch of crap to temmy bc I did not want to put up with her crap.
Muffet is actually pretty easy to beat IF you saved the spider donut or spider cider. I had it and ate it in front of her. But if you don't have one, you have to spare her 17 times, I think.
All of those attacks are just straight CRAZY!
Ok I did not vote because it's hard (we cannot be sure 'bout his gender) but because he is so easy. JUST. LET. THE. BULLETS. RUN. INTO. HIM.
Everything was a piece of cake until this fight. Took me SO LONG to get past it. Also, beware it's last attack. Those bullets are insta-kills!
What the heck, Toby!
And this site! How is this number 6?! It's worse than Sans!
After I completed my Genocide route, I was feeling like I could defeat anything. And then I remembered the Dummy in the Ruins. GOD, I had to hack the game to get past him. All monsters bow before the dummy.
Papyrus is pretty easy if you ask him on a date then he gets really distracted
No...Papyrus is easy...Plus you can skip his battle and befriend him if you die three times instead..
He was only threatening in Disbelief. In regular Undertale, he is a cake walk.
I don't think you can actually die against him - it's impossible.
Technically, you can't die in this fight, but just TRY to not get to 2 HP when you are on pacifist. It's freaking impossible!
Strangely I defeated Photoshop Flowey in three tries but on Tori on my second playthrough this was hard.
But toriel's attacks avoid you
how. do. you. not. die. 10. times.
He took me around 4 or 5 tries to beat, so not really that hard...
I don't need friends! I've got knives!
I'm out of knives.
Attacks get me sometimes(especially on dummy bot final).
Really frustrated me on my first playthrough.
Hardest boss in game. don't even tell me anything else you fool!
Froggit didn't understand what you said, but was flattered anyways.
Hardcore, I was stuck on them for a very long time. He wouldn't turn yellow, and I was so confused
Please tell me you are joking.
I've seen videos, and tried fighting him myself...EXTREMELY HARD.
Bones orange bones blue bones orange Gaster blasts sans and Undyne the undying
This is literally the easiest boss since this character doesn’t even exist
Disbelief papyrus is very hard on phase 3 because he summons sans and undyne because he’s mad I think
The blasts lol
I mean... I like his lore.
HOLY MOLY THIS IS THE TOUGHEST FIGHT EVER
yes, he SHOULD be 1st!
He is awesome and he is so hard if you think sans is hard try this dude
Lasers hands and laser moever
He kills you if you don’t have the artifact
This is actually mist likely the strongest character in the game, he created this world (undertake), so he can easily destroy it all, he could kill you (Frisk),Sans, Papyrus, Undyne, just with a single button
Hardest boss ever! Who else agrees?
Is it even a boss
Legitimately can't get rid of her in your files (unless you do some complex "hacking" stuff) so yeah
Oh jeez this has to be the hardest. Most people don't know how to battle Chara. Look it up on Youtube and watch. Most are fake actually or fan-made. Trust me, harder than Sans.
So hard can't beat it
Chara is a god. She can kill you so quick.
Alphys have lasers Gaster blasts fast forward play raced rewind and
She's not even in Undertale!
The attacks cool but difficult
Harder than any boss combine
TEMMIE for the win
Temmie for the win
HOi wElCOme tO...
Da tems to hard to beats
I feel so sorry for so sorry. He doesn't mean to fight you. He just ran into you and started the fight
Harder then muffet, undyne, papyrus and maybe asgore but not mettaton
This is a secret boss, but it's hard, I can say it's the sixth hardest boss after ASGORE
Harder than undyne, muffet and maybe mettaton
He almost instakills you with a single hit, manipulates you and makes it impossible to escape. By sheer luck they make a mistake and use a super heal on you which they could use on themselves easily! Also don't even have the option to act! They just have one attack and they go first instead of you plus they will remember everything!
This dude sssoo easy
Hell to the naaw
he's pretty easy JUST.KILL.HIM
Frisk is easy to beat. Just get her soul to run into something harmful.
Frisk is easily the hardest boss in the entire game, you can’t even hit them. Why did Toby Fox put an unbeatable boss in the game smh
Seen videos and don't even wanna try cause of how he is
;-; I don't know why did I vote for him
This dood is hecking insane, like bro.
... he has gone mentelly insane!
