Undertale Yellow - All Boss Themes 

0:01 fever pitch 1:58 forlorn 4:55 protocol 7:43 apprehension 11:09 danza! 12:33 deal em' out 14:55 showdown 16:47 tenth level lockdown

I just realized this fangame took *SEVEN* years to make. That’s how many souls they need to escape the underground… *COINCIDENCE? I THINK NOT!*

Decibat has no right to have such a banger theme

i love how it's just confirmed that decibat is a boss now, not a miniboss

It took about seven years for this fan game to come out, and you can just feel the love and effort coming from every corner when you play it, to the point where I consider it canon to the Undertale universe (as silly as that may sound). I can't even decide what my favorite boss theme is, although it does come down to Flowey's first phase, Ceroba's Kitsune Form, and Zenith Martlet's first phase (which is better than Megalovania IMO).

Decibat is genuinely adorable and it's just such a silly goober. I genuinely hated having to kill it in the Genocide route

38:56 Hopes And Dreams is that you?

I don't want to choose genocide run... ...BUT GOSH DAMN WHAT MUSIC DOES IT HAVE!!

Since the first time i heard "Remedy" there's no day in wich i haven't heared at least one time

The feisty four actually have a unique beat mixed in for every character, if you look in the audio files.

The cool thing is the fact that Undertale Yellow music is comprised of real instruments and synthesized tones and that makes it feel better than instrumental alone

This is probably the only undertale fan game without a really overpowered sans boss fight

*You are defending youself. *You are defending yourself...right? *This is self-defence, it has to be. *This is justice. *These monsters deserve death. *... *... *...right..? *You are having second thoughts. *Its too late anyway. *Why are you regretting this now? *Just move forward. *Why are you crying? *This is justice...isnt it? *Why wont the tears stop? *What? *You didnt do that? *Move forward. *You are filled with JUSTICE. *...right?

I loved Dalv’s theme.

Floweys themes go so hard, especially afterlife

What I love about this game is that no matter which route you choose you will not only get great music but really pretty image of final boss.

This fangame has so much love put into it ,that at this point I consider it canon to the undertale universe ! It fits so well with Undertale but its also really different from undertale ( in a good way!)

Holy shit the transition from "normal" flowey theme to boss flowey has got to be the best way of going into boss

My thoughts on each boss. Decibat: Looks like what happens if you canceled a Golbat's evolution into Crobat midway. Dalv: Someone on the team likes Adventure Time, calling it now. Also, Alucard backwards is... DRACULA?!! Martlet: Storm Eagle's lovable goofus of a second cousin... I mean, the guy who worked on her themes did a banger remix of Storm Eagle's theme that solely spawned a Terminalmontage animation of Storm Eagle and X having a music battle. El Bailador: The best character ever. The Feisty Four: Wait, is that Undyne's sister? AND A TANUKI?! Starlo: Yellow Fellow Redemption. Guardener: Castle in the Sky is my favorite Ghibli movie. Axis: Heh... Droids. Damaged Axis: Do robots feel fear? Ceroba: I suppose the saying "clever as a fox" doesn't apply here. Like why would you do an untested trial on your own child? Flowey: ...I know what you are, weed. "Meta" Flowey: I don't know if this is a hot take or not but... creepier than Photoshop Flowey. Specimen: Patchwork: Yoshi's Crafted World. Specimen: Organic: The Binding of Issac. Specimen: Clay: Yoshi's Island and Stop motion films. Specimen: Paper: Scribblenauts. Specimen: Polygon: You know, I think I had a nightmare as a kid of this once. Weird... Specimen: Mechanical: Cuphead. Masked Ceroba: Oh, look, a Ninetales. Zenith Martlet: You see, this is what I meant about Storm Eagle's cousin. Also, if this chick (pun intended) could fly couldn't that mean if she backtracked through the Ruins, she could leave, thus invalidating the whole story of Undertale? There's no barrier to the BACK of the cave, RIGHT?

Jeez imagine if they tried to make fangames for the other Souls, Oooof like that would take forever considering this one was Seven years!

I love how there are noticeable differences between paths in the boss themes, it's the essence of Undertale to use the Motiffs. I can notice it more in Marlet, that the instruments used in the Pacifist are in the Genocidal but they are very few. I interpret that to mean the fact that, genocidal or not, Marlet still thinks we're a very, very good person deep down.

the transition from Starlo to guardener tho

It's nice to hear the differences between Genocide Martlet and Pacifist Martlet , I just assumed it'd have the same song used 😂

I know this has nothing to have with the video but they should made a Starlo fight in genocide run like,Ceroba haved her attention in pacifist so why fight her AGAIN in the genocide? Also starlo and american flower beats are really good fr fr

Specimen flowey - clay sounds familiar (totally not deltarunes jester called jevil also could hear spamtons text noise during specimen flowey - paper theme)

I love this game to death, the soundtrack is incredible, and the fact it's free is criminal, but holy crap the bossfights made me consider abandoning my pacifist run.

00:00 Decibat 1:58 Dalv 4:56 Martlet (Pacifist) 7:44 Martlet (Genocide) 11:10 El Bailador 12:34 The Feisty Four 14:55 Starlo 16:48 Guardener 18:15 Axis (Pacifist) 20:26 Axis (Genocide) 22:03 Ceroba Ketsukane (Genocide) Neutral Run Final Boss 23:52 Flowey (Final Boss Phase 1) 26:04 Specimen Flowey (Final Boss Phase 2-8) 27:30 Specimen Flowey - Patchwork 28:34 Specimen Flowey - Organic 29:45 Specimen Flowey - Clay 31:08 Specimen Flowey - Paper 31:51 Specimen Flowey - Polygon 33:15 Specimen Flowey - Mechanical Pacifist Final Boss 34:46 Ceroba Ketsukane (Final Boss Phase 1) 36:09 Ceroba Ketsukane Kitsune Form (Final Boss Phase 2-3) Genocide Final Boss 40:50 Zenith Martlet (Final Boss Phase 1) 43:34 Zenith Martlet (Final Boss Phase 2) PS : It's for me on RU-vid music

Dalv and starlos theme are a bop to me

The characters feel so real that it Kinda gives me emotions

I like how Ceroba themes are just couples of anime and japanese theme

Floweys themes are kinda underrated

as a touhou music fan, I Love all the themes . Just Insane :)

Why is Specimen Flowey - Organic Theme so weirdly good?

holy crap flowey's theme goes HARD

Undertale is incapable of churning out mediocre music, whether it is canonical or not

In afterlife (I think thats the name of the basic specimen flowey) I can hear at some point him chanting something in the background (not the clear "fireball" but during the segment type thats first right after the start sequence)

plot twist: toby is was just waiting for this to release so he can have the rights to martlet for birdleys mom

I still have to play this game

I honestly love danza [El Balitor's theme], deal em' out, Martlet's themes and a few others👌

Every time I want to cry when I hear the genocide Ceroba theme. A melody of pain of a mother fox losing her family and now even her childhood best friend. Who now literally has nothing left to lose. The part of the tune at 23:20 especially makes me cry ; (

The feisty fours theme is easily the best

El Bailador music goes really hard

Who else also loves Dalv?

music of the vengeance route is way too good

We needed more Undertale-y stuff!😄✨

Everyone talking abt decibat's theme song Me vibing to my favourite character's theme song *dalv's theme*

Decibat: me at 3 am Dalv: description of emo Martlet: OMG IT'S BERDLYS MOM 🐦🐦🐦 Genocide martlet: ANGY El bailador: big guitar hero fan The fiesty four: the gang Starlo: you know you can't sell a gun to a child Gardener: the flower shop lady after seeing Garfield stomp the flowers on display Axis: electric box go BONK genocide Axis: mental breakdown Ceroba genocide: i keep hearing it... Its everywhere... Flowey final boss 1: AYY WHERE THE PSYCHOLOGICAL HORROR COMIN FROM??? Flowey final boss 2: ms paint flowey Patchwork flowey: that one plushie you find in the attic Organic flowey: COUGH Clay flowey: spamton at the start? Paper flowey: he really let himself go Polygon flowey: ok that's scary 😱😱😱😱 Mechanical flowey: how many are there??? Ceroba final boss 1: can say this is anime as frick Ceroba final boss 2: NINE TAILS????? Martlet final boss 1: your mom when you don't do your chores Martlet final boss 2: AN AMALGAM AAH

i love axis pacifist and starlo so much that its a vibe for it

Starlo is so freaking good guys omg

U have no idea how badly i wanna make a song with the same mood and intensity as a mothers love Edit:if u dont wanna read the replys ive made it and the songs on my channel rn

Flowey is scary ☠😱

What we learnt? UTY has banger songs.

That actually fun game for all fans on undertale community, and i'm so glad see that's masterpiece ❤

Decibat remind me of a certain game? LEGEND OF ZELDA

my favorite songs, are all martlet themes ( except retribution), all ceroba themes, guns blazing, specimen flowey, and starlos theme

I love it!!!!

Trial by fury and guns blazing are the best ones

specimen:Mechanical and no point of return are definitely 2 of my top picks

I love that polygonal has like the ocarina of time soundfont. It fits it so well

The feisty four music kinda sounds a bit similar to the Cuphead boss fight themes

Nice

Paper flowey song goes hard for no reason

I don't understand why, but I really like sTarlo's song, it's just full of determination, sadness, notes of the wild West, JUST WOW

Let's gooooooooo man did Undertale Yellow wwwwwwww

36:08 A Mother's Love...

Just the best Undertale fangame of the history

Clover would like to cry but they don't have eyes 23:52

after defeating Zenith Martlet, i can hear this soundtrack in peace

I noticed something, For the feisty four, You can see the 4 Icons from deltarune are there. Spade, diamond, clover, and heart.

Question, can you pull out all of the final boss themes from Final Fantasy franchise?

imo Decibat/Dalv and Starlo are some of my favourites, idk they just sound so good.

specimen: patchworked's design reminds me a lot of fnaf world and i love it

спасибо за видео

I love Flowey's 2 themes (In the phase 2, Flowey's other form are part of their phase)

I think apprehension is another version of protocol.

[lovely]

29:45 After so many monts , I realized that there are similar parts of The World Revolving

OMG I JUST REALIZED, AT 15:15IN STARLOS THEME, YOU CAN HEAR THE EDDSWORLD INTRO SONG

I really feel like ''Tenth level lockdown'' doesn't really get much recognition for slapping THIS HARD while not even being the main boss of the area.... This ost is as good if not better than fever pitch to me. What was up in UTY developpment team, what was the decision that even not main bosses should get ABSOLUTE BANGERS ?!

Yoooo i will listen to this music a hendred and hendrer of time

when i was going to do genocide and i was so sad about have to kill the bat BUT i killed all monster before the bat encounter and he dont showed up i got very happy

Is it just me or does the Flowey mechanical theme feel a lot like an ULTRAKILL theme?

i didn't know that Marlet changes her song depending on the route, epic

Why does zenith martlet theme sound like a legendary Pokémon battle song

I just went through the game, to the pacifist ending. I'm crying😭😭😭

zenith martlet looking majestic

Martlet by far has the best themes

dalv is a banger

WE UPLOADING THE GAME'S SOUNDTRACK AGAINST THE DEV'S WISHES AND PUTTING SPOILERS IN THE THUMBNAIL WITH THIS ONE 🔥🔥

Decibat and El Bailador best characters

Well, is incredible the music of the people of undertale yellow ❤❤❤, i love the video

Zenith Marlet sounds like a Pokémon theme

Is it just me or is the guardener's theme hella underrated

The axis (genocide) music is a banger

Undertale yellow have a amazing OST, but one of my favorite is retribution (Zenith Marlet second phase) it just awesome

My favorite: Forlorn Guns blazing BEST FRIENDS FOREVER
