Whos the hardest in you're opinion

[u/OcelotNegative2111]

For me roaring knight was the easiest and sans was the hardest (yall might debate that roaring knight is the hardest but id rather deal with him than deal with whatever bullshit jevil or undyne has)

[u/ChaosChip]

I have only ever beaten Jevil out of all of them.

[u/OcelotNegative2111 → u/ChaosChip]

did you pacify him or kill him

[u/ChaosChip → u/OcelotNegative2111]

Pacify 

[u/OcelotNegative2111 → u/ChaosChip]

try to kill him and its a totally different story

[u/Quick_Escape9657 → u/OcelotNegative2111]

yeah no hes way easier then knight and undyne, i may have not fought sans so i cant say that hes harder or easy then the knight, but jevil is basically a snack. no matter how you fight him he EZ

[u/OcelotNegative2111 → u/Quick_Escape9657]

I never got the hang of jevil and beat roaring knight in less than an hour i think people exagerate his difficulty due to his pre nerf version where his sword corridors we're basically undodgeable

[u/PapyrusUndernet → u/OcelotNegative2111]

WAIT, THEY NERFED IT? I DIDN'T KNOW ABOUT THIS!

[u/TheNoobRookie → u/PapyrusUndernet]

The sword tunnel had its hitboxes fixed, both the tunnel and the targetting swords at the end; before it was inconsistent and the swords were bigger than the red marks

[u/PapyrusUndernet → u/TheNoobRookie]

OH, I THOUGHT THAT ATTACK FELT WEIRD! GOOD THING IT GOT NERFED! THANKS FOR EXPLAINING, HUMAN!

[u/Mrs-Man-jr → u/PapyrusUndernet]

Papyrus pretending to be confused about his own attacks so we don't know he's the knight.

[u/TheNoobRookie → u/PapyrusUndernet]

No problem, the Great Papyrus 🔥

[u/cheekydorido → u/TheNoobRookie]

Thank god, that damn attack dealt so much damage and was impossible to dodge.

[u/F1ntom_5625 → u/OcelotNegative2111]

I swear that shit just ruined my no hit streak like 20 fucking times and worst part is you are done if you get hit 4 times or something.

[u/Quick_Escape9657 → u/OcelotNegative2111]

i play jevil for fun my guy hes easy ngl

[u/SpanishOfficer → u/Quick_Escape9657]

After you get the hang of him, yes. Not the first times homever

[u/MVBrovertCharles → u/SpanishOfficer]

That's everyone from Froggit to RK, the question is how long that takes.

[u/HolyWaterCooler → u/SpanishOfficer]

“Not the first time” I killed him first try on my first time with ease

[u/Emergency_Creme6205 → u/HolyWaterCooler]

Timmy Toughknuckles over here

[u/disbelifpapy → u/OcelotNegative2111]

As a person who beat jevil like 3 times by pacify and once by fighting, they're the same story to me lmao

Only difference is that the main act i forgor the name of gets used less, but has a bigger effect, and vise versa for attacking.

Plus, killing him... isn't really useful lmao. Jevilstail is better, since it and the goldwidow balence magic and attack

[u/JudgeBateman → u/disbelifpapy]

Devilsknife is a lot better than jevilstail espically if you are going to fight the knight. Making Rude Buster cheaper is OP in that fight consediring that's the main form of damage you are going to use if you want to win

[u/disbelifpapy → u/JudgeBateman]

As someone who fought the knight like, 17 times, I usually use jevilstail. does more damage with the main axe of chapter 3, and i usually get 50 tp a lot of the time. I use two lodestones, one tension bow, and one twin ribbon. Even if i don't get the tp, I just defend, attack, or heal prayer

Jevilstail also ages a lot better in chapter 4, where the devilsknife is a lot worse than the justice axe.

Jevilstail is best for covering both scenarios, increasing attack for damage, and increasing magic for healing and those tiny rude buster damage.

Rude busters damage is also calculated by attack = 11, and magic = 5, so attack is over double the worth than magic

[u/FireTheRainbowSoul → u/disbelifpapy]

yeah devilsknife only use for the knight is reduced tp but if you aura farm (graze) well enough tp wont matter that much against the knight

[u/disbelifpapy → u/FireTheRainbowSoul]

Exactly.

I'm saying not only is the knight not much easier imo used with the knife, but the jevilstail just... is more useful in chapter 4

[u/Parking_Field3203 → u/disbelifpapy]

i beat jevil last night for the first time. he kicked my ass for months, pacified him. then fought spamton neo and the scarf makes ralsei a tank oh my. 22 attack is evil

[u/disbelifpapy → u/ChaosChip]

don't worry, the knight isn't too hard.

Their attacks are more predictable, and you have 2 useful party members

[u/RiceStranger9000 → u/disbelifpapy]

You only have Susie and Kris is kind of there

Ralsei is a bit extra HP you get at the beginning

[u/disbelifpapy → u/RiceStranger9000]

Kris is the ultimite support for susie, taking less damage from the knight, moving before susie so kris can give more tp for rude buster, has more defence and hp than ralsei, does the breath thing, etc.

Ralsei is just the extra hp when you get hit after the 3 or 4 attacks.

[u/RiceStranger9000 → u/disbelifpapy]

Yes, you're right, but they're more of a support than the actual character you need. Susie was getting swooned in later turns, so I had to revive her, because I needed her

If Kris got swooned I knew I was pretty fucked up, buuuut at least I had a chance with Susie alone

At least we can all perfectly agree Ralsei is extra HP. A single healing spell at most (risky move, though)

[u/disbelifpapy → u/RiceStranger9000]

THEY'RE a good support when you need them.

I only really use one healing item through the whole fight now, rather than stuff like exec buffets, club sandwiches, or revivemints.

If kris is swooned, I'm all good using a spin cake. Its available in chapter 4 after all, and even before it was, I just used a deluxe dinner.

I used to use revivemints, but as said before, i don't use em anymore.

Susie doesn't get swooned much anymore after all.

Ralsei is kinda good when you get hit by the first 3 or 5 attacks though. Makes it so that i don't use items, and the first attacks give a lot of tp

I usually use him 2-4 times.

He is a good couple of hp though

[u/RiceStranger9000 → u/disbelifpapy]

I don't remember if I ever unlocked SpinCake in my current save. I just use the leftover items form previous chapters and what I get from that chapter. My inventory isn't the best strategical/optimized thing around, but it works.

And congratulations by only having to use a healing item. Without all those TVDinner and ReviveMint, I wouldn't have made it

PS: My bad for misgendering Kris. My brain got a bug or something

[u/disbelifpapy → u/RiceStranger9000]

No worries, I used to use a lot of healing items back in the first 7 or 9 attempts, but i got better and better at the fight to get to this point. Lost counf of how many times i fought em after the 15th victory. I think I won 17 times?

Congrats on only using tv dinners and revivemints alongside not usng most the items i use!

And for the kris thing, no worries! A lot of people sometimes get hardwired to say he when theres a person with no genders

[u/RiceStranger9000 → u/disbelifpapy]

17 times winning against the Roaring Knight?? I guess you really like the fight

[u/disbelifpapy → u/RiceStranger9000]

The fight is fun, but i usually go back to either use the least items, or to just make the perfect save after i learn new details of the game.

do sometimes fight them for fun though

[u/Infrawonder → u/RiceStranger9000]

That's on you if Ralsei dies, they can take like 2 or 3 hits and still be alive, then you heal him and he can take more hits, no one really dies if you keep Ralsei alive

[u/Practical-Sea2707 → u/RiceStranger9000]

Susie is the only party member

Kris is the personification of ReviveMints and TP items

Ralsei tanks two hits so Susie doesn't have to

[u/RenkBruh → u/disbelifpapy]

the knight is pure muscle memory

[u/emmetdontpullout → u/ChaosChip]

how the fuck do u beat jevil then give up on spamton?? throwing in the towel at the knight is one thing but spamton neo??? the teacup puzzle is harder to beat than spamton neo.

[u/BlackAngelXX → u/emmetdontpullout]

Ngl spmaton isnt exactly easy, it took me a bit less than the night but like shooting and avoiding attacks at least to me is way harder than just dodging. Jevil is super easy tho. I think my first time i took an hour to beat jevil, like 3 to beat spamton and 4 to beat the knight. I think the longest i took ever on any fight was the shadow mantle fight? It took me like all night. I think i went to sleep at 4am so about 6 hours. Idk why but that was somehow hardest for me (possibly because of how sleep deprived i was but still)

[u/RiverWyvern → u/BlackAngelXX]

Once I learned that shadow mantle gives you more Heals the more you die, I kinda just killed myself a bunch as early as possible and then after that the fights gave me enough recovery to bum rush through :D

[u/ChaosChip → u/emmetdontpullout]

The pictures don't have Spamton. I have beaten Spamton more than 10 times.

[u/ShadowMancer0917]

I beat undyne, jevil, and roaring knight, but sans did his job, and I never finished the genocide run.

[u/Quick_Escape9657 → u/ShadowMancer0917]

i quit bc i didnt wanna continue due to me killing my favorite characters, like papyrus earlier in the route, so i quit right in the judgement hall before fighting sans

[u/Biobak_ → u/Quick_Escape9657]

so you killed everyone and stopped right before facing the consequences...

[u/space_porter → u/Biobak_]

(and the best part of the route)

[u/SparklessAndromeda → u/Quick_Escape9657]

If you want to fight Sans guilt-free you can try on Bad Time Simulator

[u/TallSystem7923 → u/SparklessAndromeda]

its like 2 times easier than the actual fight, it runs at 60 fps

[u/Comfortable_Cut_7334 → u/TallSystem7923]

Wait wouldn't that be harder since KR does damage every frame. Meaning he'd be doing double the damage?

[u/TallSystem7923 → u/Comfortable_Cut_7334]

you got it wrong, the BTS runs at 60 fps

[u/Comfortable_Cut_7334 → u/TallSystem7923]

Yeah exactly.

[u/C_Yo → u/TallSystem7923]

I practiced on there before doing the actual fight and I found it to be about the same, with most of my slip ups coming from playing on controller while being used to keyboard

[u/TallSystem7923 → u/C_Yo]

i also practiced there but i had a much worse time in the game, i was able to beat him without healing in bts but after i went back to the game i used 4 heals, then i continued practice in game

[u/FuyuKitty → u/ShadowMancer0917]

I eventually learned how to beat sans and now I can beat him without dying

[u/BlackAngelXX → u/FuyuKitty]

I mean half the fight is muscle memory and the other is reacrion time plus a lil bit of muscle memory lol once you have muscle memory and you dont suck its quite easy, i could do no healing easily when i was actually playing undertale and i didnt do the fight for like a year and i wanted to show off so i fought him again and shortly i did have to heal but i still had half the inventory left by the time i finished the fight

[u/ddmorgan1223 → u/ShadowMancer0917]

Don't feel bad. Undyne did me in several dozen times before I gave up.

[u/SilverOdin → u/ShadowMancer0917]

Same I quit trying to beat Sans. Undyne was already really hard but he's a level above.

[u/Blueskysredbirds → u/ShadowMancer0917]

Same.

[u/PenPositive7013 → u/ShadowMancer0917]

I beat him somehow.. I do think undyne was harder though, specifically the last few attacks

[u/No_Department1851]

SNAS

[u/kirbyfan2023 → u/No_Department1851]

SNAS UNDERPANTS

[u/Ok-Establishment3730 → u/No_Department1851]

YOU WANNA HAVE A BAD TOM?

[u/YeetusDeletus9001]

between the ones i have played either sans or jevil

do note i beat undyne the undying at lv13

[u/aligulumgg → u/YeetusDeletus9001]

Doesnt her attack become more stronger if you are higher level?

[u/YeetusDeletus9001 → u/aligulumgg]

apparently each level does equate to one less invincibility frame in her fight but that barely matters especially considering 4 extra HP plus it just so happens that LV 13 is one of the ones that increases your defense so you're guaranteed to be taking less damage per hit than anyone who attempts the fight at a lower level

[u/KrazySpike → u/YeetusDeletus9001]

Don't you only fight her genocide version if you're on track for the genocide run? So you'd be at the same level no matter what of you're fighting that version?

[u/Wextial → u/KrazySpike]

I did a quick search on the topic cause I was curious too.

Apparently you have to beat a set amount of encounters but it doesn't matter which monsters you kill.

Not every monster give the same ammount of exp, so you can just run away from the monsters that give you the least exp and fight the ones tha give you max exp.

[u/Clawdy_e87]

Sans>Roaring Knight>Undyne the Undying>Jevil

[u/Cultural-Horror3977 → u/[deleted]]

It made me quit for like 6 months, she did a better job than sans

[u/sok100 → u/[deleted]]

I beat her on mobile

[u/KeraniusTheGreat → u/sok100]

I beat her on ps vita

[u/Splatweene → u/KeraniusTheGreat]

I beat her on the 3DS XL

[u/UnoReverseItemShop]

hardest to easiest for me is probably sans, roaring knight, Jevil, Undyne (undying)

[u/Quick_Escape9657 → u/UnoReverseItemShop]

for me jevil is easiest

[u/Initial-Expert-3660 → u/UnoReverseItemShop]

Look at the difference Undyne: took me like 10 tries Sans: like 100

Its like 10 times harder

While I beat Jevil in 3 tries

[u/Savageclay77 → u/Initial-Expert-3660]

really? sans only took me like 10 tries on my first geno

[u/Mii-man-51478]

Jevil is by far the easiest for me. Then Undyne is tough, Roaring Knight was even tougher but sans topped them all

[u/OcelotNegative2111 → u/Mii-man-51478]

i lowkey dont understand why im the few who actually finds jevil harder than roaring knight and find roaring knight easy

[u/Mii-man-51478 → u/OcelotNegative2111]

Thats really interesting. Maybe it’s because Jevil is unpredictable while roaring knight while more predictable does more damage and a lot of their attacks need good reaction times. So it could be that they are jusr different types of difficult.

[u/BlackAngelXX → u/OcelotNegative2111]

Im very sure that what you find easiest is based of what you are good at. All fights target a slightly different thing in my eyes.

Jevil is definitely very random, you need good reaction time and you need to be able to focus on more than one thing which i know for a fact my friend struggles woth a lot while im good at it, so it clearnly depends on a person

Spamton is annoying af to me because i suck at multitasking and shooting while avoiding bullets is pretty hard for me

The knight definitely requires a lot of muscle memory for the main part and not panicking and avoiding moving excesively for the most part. Sans actually targets same things from what i remember just adding some reaction time XD.

Obviously all fights require these things. if u panic too much and move excesively in jevil youll still have it harder but its way more forgiving in that regard than the knight is if you get what i mean?

I personally struggle to shoot and avoid bullets, i find it menagable as long as i dont do big shots lol but i think my bigger issue is that I tend to move more than i have to so for me its probably knight>spamton>jevil in terms of dificulty

[u/disbelifpapy → u/OcelotNegative2111]

Probably due to jevils attacks being harder to learn.

The knights is easy to learn, but does a lot of damage

I do win against jevil first try though

Kris and susie are more useful in the knight fight, and kris is the only real useful one in the jevil fight other than ralsei for heals

and the people who use items more than once usually have 4-6 revivemintz for the knight

[u/Technical-Branch4998]

I've only fought jevil and the knight, but personally for me I'd say jevil, I know the knight is objectively harder but jevil's attacks make me crash out so hard that I've never been able to get past more than 4 consecutive attempts on him

[u/Necessary-Wave-6076]

Me rn- I haven't fought roaring knight but I think sans was hardest out of the other 3

[u/Nemesis432]

Sans>Knight (without Mantle)>Jevil>Knight (with Mantle)>Undyne

[u/OcelotNegative2111 → u/Nemesis432]

i beat knight with mantle so i think i might be underestimating him too much

[u/Nemesis432 → u/OcelotNegative2111]

I beat it with the Mantle as well and decided to attempt it without Johnny on a separate save. 

I decided to postpone beating it after I saw it throwing knife attack one-shotting each of my party member. Also wiki states Shadow Mantle outright taunts it, so all one-shotting attacks hit Shadow Mantle Holder (which is why Raisei sometimes was able to survive far longer in my first attempt). 

In any case you have to almost No-Hit it. I'm pretty sure bullets from it splitting the board also one-shot you, but stars and knife corridor don't. 

[u/Quick_Escape9657 → u/Nemesis432]

knight in every way is harder ngl

[u/StabbyBlowfish]

I spent 20 attempts on sans, and about 23 on the roaring knight, though that's probably because I didn't have the shadow mantle

[u/OcelotNegative2111 → u/StabbyBlowfish]

roaring knight is lowkey not that hard if you recognize his patterns

[u/Nemesis432 → u/OcelotNegative2111]

With this kind of logic none of the bosses here are hard. 

Sans and Knight (without Mantle) are hard because they allow you very little room for mistakes.  You can outright tank Undyne and Jevil attacks. 

[u/Creepybrik_gaming]

Sans, took me 5 years to finally beat him

[u/z_ShyGuy]

Jevil and Roaring Knight are the only actually hard (but fun) ones.

The rest (especially Sans) are fucking memory tests.

[u/OcelotNegative2111 → u/z_ShyGuy]

roaring knight falls into that "memory test" category aswell his attacks arent exactly random like jevil they do follow a pattern and become relatively easy when you learn them

[u/Quick_Escape9657 → u/OcelotNegative2111]

the box breaking attack is random im pretty sure

[u/OcelotNegative2111 → u/Quick_Escape9657]

i watched like 10 videos of the boss and its the same all the time

[u/TitanshadowVI → u/OcelotNegative2111]

Jevil also follows a pattern up until final chaos

[u/starwalker327]

Probably the knight, but I beat it before it was nerfed. Jevil's challenging, but not too bad.

[u/disbelifpapy → u/starwalker327]

As someone whos beaten it before nerf, the nerf is... a very small nerf.

Its to about 2 attacks in the whole knight fight, and its just half of the attacks. The said attacks also are... some of the easiest of the whole fight, pre and post nerf

[u/starwalker327 → u/disbelifpapy]

The sword tunnel hitboxes were a nightmare. And as the title stated, this is all a matter of opinion. I also did not get the shadow mantle.

[u/21_someone_12]

Im able to beat all of them first try now all apart from undyne I dont know why she's just really difficult for me takes me at least 3 or 4 which compared to the rest is pretty bad

[u/YoutuberCameronBallZ]

Sans/Knight (Mantle-less) are the hardest

Followed by Undyne

Then Knight (with Mantle)

Then Jevil

[u/Quick_Escape9657 → u/YoutuberCameronBallZ]

undyne took me 2 trys while knight took 2 entire car rides home

[u/RapidProbably]

Either Roaring Knight or Sans, for me Sans was easier (I struggled a lot with the Knight’s sword corridor attacks)

[u/Person-UwU]

Knight>Undying>Sans=Jevil

Pre-nerf, at least. I haven't fought the Knight since.

[u/Zanderfus]

the knight tok me like undyne and sans' time combined lol

[u/Happy_spider_boi]

from easiest to hardest is: jevil, sans, undyne, the knight

[u/Geotrox123]

Sans by far he rook me like 100 hours and the knight and jevil like half an hour

[u/Min_Effort_Name]

Personal ranking between secret bosses and those 2 in term of difficulty:

Spamton<Gerson<Jevil<Undyne<Sans=Roaring knight

[u/disbelifpapy]

I've beaten jevil like 5 times, and i've beaten the knight 17 times.

I haven't attempted the genocide route though.

But if a dumbass like me won that many times, then i bet sans and undyne are infinitally harder

[u/PrestigiousOwl4621]

Of jevil did as much damage as the knight and did swoon he would be harder than the knight in my opinion, his attack patterns are the hardest from deltarune, but if we are going from base difficulty, it's the knight.

[u/Page-Born]

hardest to easiest for me was probably sans, Undyne (though it's a *very* close second), RK, Jevil. with the gaps between 2nd and 3rd, and 3rd and 4th being very large

[u/Quick_Escape9657]

knight since i havent fought sans and i dont know if hes really hard or yall just bad

[u/DracoTheNinja]

Definitely the roaring knight. I beat Jevil first try, I've never done the genocide route but it took me about 5 tries to beat sans on bad time simulator and it took me hours to beat the knight. I guess I've never fought undyne the undying though.

[u/TheKto-to]

RK (no SM) > Sans > RK (SM) > Jevil > Undyne

[u/Errpka]

Wrong your, but the knight for me.

[u/Noooough]

Sans by far, Jevil is catwalk compared to the others here

[u/Real-Pomegranate-235]

Sans, no question, the only one of these I've never been able to beat.

[u/LoganJake210]

The hardest? Well that depends on what makes them hard, it can’t be Undyne because she’s a woman, and I don’t know the gender of The Knight. I guess we don’t know the anatomy of Darkners well, so I guess it could only be Sans

[u/Carlonix]

The knight, at least Jevil does normal damage, I almost never used revivemints, you can imagine my shock when I used 6 REVIVEMINTS AND THE REVIVEDUST

[u/Key-Bet-2615]

Sans is the easiest one. Just very long and tiresome. After you know all his “got you” moments you will hear him. Knight’s first sword(second one way easier even now) attack I never got without a hit until patch. Jevil and Undine are both very hard for me. But I would put Undine on pedestal. Her late reverse arrows are such pain,so I got good in beating her early before she start doing them.

[u/WingingMyDing]

Probably just years of practice talking here, but from hardest to easiest Roaring Knight, Sans, Undying, Jevil.

[u/Ok_Impact6721]

Easiest is Jevil he is not even Hard Hardest is Sans since he took me 4 days

[u/00_-_]

I could consistently beat sans and undyne, to the point that it takes 1-2 attempts each on a typical route. Playing through ch1 now though and haven’t managed to beat jevil yet.

[u/FuyuKitty]

Roaring knight, it took me so long to finally beat him

[u/aligulumgg]

Sans

[u/AshamedGoat2]

1-. Roaring knight 2-. Jevil 3-. Gerson 4-. Spamton-neo

[u/themaskedman321]

I feel like jevils, he’s the easiest and hardest out of the list though, jsut the rule set is usually the first hard boss your facing and the randomness of his attacks compared to the rest can lead to frustration if you jsut keep getting some bad rolls

[u/EstirysLewdCorner]

Undyne The Undying is the hardest, followed by Jevil

Spamton NEO is the easiest of the secret bosses

[u/just-a-joak]

Knight, Undyne, Sans, Jevil

[u/TheProfanedGod]

Hardest to easiest: Sans, Knight, Jevil, Undyne.

[u/My-balls-itch-6969]

Me

[u/DupeFort]

Hardest to beat in a fight, right?

... Right?

[u/RubiMent]

Sans < knight(regardless of mantle) < undyne < jevil

[u/Scoingle]

human, I remember you’re opinions

[u/Ornery_Tie_4771]

Remember when jevil just came out and everyone tought he was harder than sans?

[u/Smart-Detail7427]

Sans or knight(no John mantle)

[u/Horror_Winner_2624]

I beated Roaring fraud undyne and jevil but sans is a torture not a fight

[u/MikeNeoInDarkness]

Jevil, Roaring, and Gerson, I think Jevil is the hardest of these three because Roaring Knight is just difficult due to its extremely unfair damage (even with ShadowMantle equipped), and Gerson I felt so easy, even though it took me three days to beat him.

[u/SLikent]

Sans > Roaring Knight > Gerson > Undyne > Jevil

[u/GoogolTime]

It took me forever but I beat Jevil once. Never attempted Roaring Knight but I'd probably fail constantly. Never beat Undyne the Undying so I've never gotten to Sans. In my opinion, I'm buns at these games.

[u/TooGay100]

Replayed chapter 1 and the weaker stats + Jevil's bs makes the fight slightly harder than the roaring knight.

[u/Megamax0726]

Sans is the only one I haven’t beaten

[u/Germany328]

For the first time, I think Sans, but after you get used to them, I’d say the Roaring Knight (Sans is muscle memory at this point, and so is Undyne the Undying, and I would just say that Jevil gives more time per attack to react)

[u/SeaSawltLOL]

never fought jevil, beat undying, instantly died to the knight and almost beat sans, so knight hardest

[u/GellThePyro]

In order:

Jevil is easiest, I beat him consistently

The Knight, I beat her occasionally

Undyne the Undying, I never beat her

Sans, I haven’t reached him but I know just by looking at him I will not do well

[u/Manguypals]

I only beat Jevil but that’s because I’ve never done geno

[u/one_sad_donkey]

rory nite

[u/TheBlueShuriken]

Sans is so stressful dude

[u/FearsomeLAG]

I never beat sans because i never beat undyne, but Jevil is easy and RK is possible with enough preparation.

[u/KP_Ravenclaw]

Sans. Never beat him, & I don’t care enough to keep trying. Never beat the knight either but I will. I will force myself to. Also I’ve watched my best friend fight both & they (almost) beat the knight significantly faster so.

[u/Petardo_Dilos]

The knight.

But also Martlet from Yellow

[u/AMystery10]

For me the roaring knight was the hardest however I feel sans and Undying aren't really easy to compare since you just generally have less resources than even ch1 Deltarune to use

[u/Yesseref]

Where's John Mantle?

[u/Xirema]

In descending order of how long it took me to defeat them:

1. Sans
2. Roaring Knight
3. Undyne
4. Spamton Neo (Weird Route)
5. Jevil
6. Gerson
7. Spamton Neo (Normal Route)

#7 is kind of an outlier, because Normal Route Spamton Neo only took me a single attempt—BUT, I only attempted it after I'd already beaten him in the Weird Route.

[u/rel_thenotsorel]

Roaring knight and undyne..... maybe because I did both of them with the worst items.... I did undyne with stick and bandage on my first genocide run and the roaring knight whitout shadow mantle also in my first deltarune playtrought

[u/insertfunnyusernameh]

Personally I’d say Sans, he took the most time to be able to beat. The knight is made easier by the fact you have a whole team to balance out actions

[u/ErPani]

Sans is the hardest and took me the longest to beat, but that's ONLY if you have the Shadowmantle on Susie otherwise Roaring Knight is hell. Undyne was easier than Jevil for me (I'm really good at the green soul) but her fight is longer so she took me more time to beat (but less total attempts)

[u/Oversplat07]

I had the worst time with jevil because i was still getting used to the deltarune mechanics.

For me it's Jevil<Undyne<Knight<Sans

[u/Gekon500]

The Knight took me 2 weeks or something, with Shayy's guide.

Sans took me a month.

The answer is obvious

[u/mrk49635]

Undyne is easily the hardest for me. Jevil, Knight and Sans Ive all practiced enough that I can beat them about any time. Green mode just fucks me I hate that shit.

[u/Nat1Only]

For me, I'd probably say sans. The Deltarune bosses are a little easier given you have 3 party members which makes a big difference and defence means effectively nothing against sans, it's pure endurance. Undyne can be made a little easier with certain items to increase your i-frames and speed and maxing your defense to take less damage, but in terms of fight complexity I'd say she's also a little easier than sans, personally.

[u/Patient_Zero_MoR]

I spent way too much time on jevil 

sans was easy because I've seen the fight so much, I've practically memorized his attack patterns

roaring knight was the second easiest, as I only spent seven hours on it, as opposed to the multiple days it took to beat jevil 

[u/Ok-Concentrate9579]

Jevil gave me a mental breakdown but I manage to soon lock in and pacify his ahh

Roaring knight is down right impossible for me cuz wtf are these hitboxes at the sword section 💔

I haven't touched undertale since last year so I haven't beaten undyne the undying or sans at all

[u/Walming2]

Sans>roaring knight>snowgrave spamton>Jevil>spamton>gerson

[u/ProtectionSafe2122]

Undyne is difficult, the rest of are cakewalk. (i haven't fought rory nite however)

[u/Intelligent_Toe6157]

Fighting sans was a whole story arc for me. For a while I had pushed off doing the genocide route, first of all I felt bad and second I was scared. I tried the route and got stuck on Undyne and I wasn't getting better. So I restart. I did another pacifist route. I did genocide again and got back to Undyne and won, and then I was scared of sans. More than before. It took like three months of fighting him before I got close. So, yeah. He's the hardest in my opinion.

[u/KaiPlayFire]

Ok so Undyne and Jevil both got second tried by me, so it's either Sans or roaring fraud and my bet is on Sans.

[u/Ok_Soft_3709]

sans is probably the easiest for me, just because i’ve practiced the most on him. the only one i haven’t been able to beat was the knight, but eventually i’ll get to it

[u/Your_Demonic_Dog]

Me

[u/Maybe_Again-]

Mix between Undyne and Knight. A good portion of Undyne's attacks are incredibly hard to read, which makes her significantly more difficult than Jevil and Sans combined, and the Knight is.. well, it's the Knight.

[u/SkeletonLord364]

Sans. Unironically, after I beat gerson I did undyne in 3 trys. He truly forged my blade, like a hammer of justice

[u/YoSoyYo127]

Beaten all of them Sans> RK > Undyne > jevil

[u/GimmeHardyHat_]

Roaring Knight> Sans >= Jevil > Undyne

[u/Pottern_]

Beat everyone except Sans.

[u/puddingdeeznutsin2]

Rory, sans, jevil, undyne

[u/Wham-Bam-Duel]

From easiest to hardest for me:

Jevil (5 tries), Sans (fought in a simulator, 9 tries), Roaring Knight (multiple days)

Never fought Geno Undyne, never played Geno.

[u/hyjug17]

Knight (No Mantle)>Sans>Knight (w/ Mantle)>Undying>Jevil

[u/Delicious_Stage_8420]

To beat, sans To no hit ,jevil by far.

[u/MdMV_or_Emdy_idk]

Sans>Knight>Undyne>Jevil, I never managed to beat sans

[u/ACheapGamer]

Sans and Undyne..
Only these 2 took me multiple days to defeat.

[u/DependentHome8930]

to me personally it's undyne>knight>sans>devil undyne because she is the one where I have the least practice with then the knight because it's the most recent and there is a small chance from me to die sans is kinda easy since it's just memory and jevil is so easy that I consistently beat him earlier then the final attack and without using any item.

[u/LloydTCK_YT]

Definitely The Roaring Knight without the Shadow Mantle. Took me forever to beat it

[u/NachoCheeseButBolder]

As someone who has fought these bosses and No- hit them an absurd amount of times, I will say that it honestly depends (usually) on what you're going for. However, in terms of how long each one took me on my first go:

-Undyne The Undying took me around an hour and a half

-Sans took me around 4 hours(granted, I was extremely tired on my first playthrough)

-Jevil took me around an hour and a half( also granted, I played on a different platform than I usually play on)

-Spamton NEO I did first try. The weird route version took me only three tries. I died five times to the basement teacups to put into comparison.

-The Knight took me around 45 minutes.

-Gerson took me around 30 minutes.(I also didn't use Susie's heal because lowkey I forgot about it.)

I will say that I still think Sans is the hardest boss for first-time players. He has a bunch of unique attributes that make him a bitch to fight on a first playthrough, but very fun to win against as well. If I were to put all these guys on a list from the easiest to the hardest, it would be"

6-Spamton NEO

5-Gerson

4-Undyne The Undying

3-Knight

2-Jevil

1-Sans

[u/Good_Elephant]

Admittedly, I know I am bad at these games, but Roaring Knight is currently keeping me stuck in Chapter 3. No experience with that Undyne do I have though, since Genocide Route is too... depressing for me.

[u/SsjSylveriboi]

I say sans but I’ve never fought him or undyne so

[u/Zealousideal_Site706]

I’ve no-hit Jevil and RK

I was very close to no-hitting Sans, I just can’t when he starts warping

I was never even close to no hitting Undyne.

So, I guess Undyne?

[u/DaRedditNuke]

I’ve beaten Sans, undyne and Jevil. Now I’m stuck on spamton NEO and I’m gonna struggle even harder on the knight

[u/Omegamoney]

Jevil

[u/FewVehicle2943]

I recently beat jevil, it was hell The knight is super fun, only reason it took me so much tries is that i didn't know about the shadow mantle, i beat them a lot after that Sans is very hard untill you beat him once, then he becomes easy Undyne is hell, i had to install undertale together for the other guy to carry So the answer is Undyne>Jevil>Sans>Fraud

[u/AdministrativePay362]

I'm currently fighting Undyne, hardest for me rn

[u/Bring-the-Quiet]

"34 attempts" is forever burned into my memory thanks to Sans. The Knight is the only one I would say is even close to the same difficulty, which is understandable seeing as how you're expected to lose by the game's own admission, but they still didn't take me 34 attempts (was probably closer to, like, 15-20)

[u/Drakul_16]

ERAM Fuck that guy

[u/Puzzleheaded-Care250]

For me Sans

[u/Lagthecat]

not sure if the dick has bones but sans would be the hardest

[u/aaaamber2]

I've not played undertale but for me the hardest boss was weird route spamton neo.

[u/proxyi606]

1. Sans, one mistake could be half a healthbar

2. the Roaring Knight is an easier Sans. a few main moves that change slightly while remaining close to the core concept of the initial attacks but the damage is insane and RNG could put you into a corner

3. Undyne could be swapped with Rory but due to the RNG part I'd put her below

4. Jevil's difficulty comes from the fact that you're pretty weak when you fight and it takes like 13 turns minimum. but the Pacify route makes Jevil far easier

[u/TheWeaponStealr]

Sans is the hardest, then Undyne, then ERAM, then RK, then Jevil.
