Top Ten Undertale Boss Themes

Glad this one's at the top right now! It's definitely my favorite boss theme.

I love the rhythm and the pitch it goes. It is just beautiful.

Death by Glamour gives me amazing vibes. My favourite one.

Well, this is a pleasant surprise.

My teacher: Time for a math session! Megalovania =?
Every student: The best boss theme ever!
My teacher: No, not quite.

I then grab a shotgun and shoot her like crazy.

How is this not first?! This was my favourite song of all songs for some time!

Easily my favorite song. (Well, besides 'Song that might play when you fight sans (I love Sans))

Why is this only #5 with just 9% of votes? WHY? DO YOU WANNA HAVE A BAD TIME?

I'm not the person who likes drums and hopes and dreams isn't for me, I like them all but my favourite is asgore

this one is sooo good it starts out kinda sad, sure but the song itself I feel is misinterpreted
the theme goes right along with the type of boss fight it is it is definitely in my top 5

This theme is extremely catchy and always gets stuck in my head. I love it to death and I think it deserves more love.

I love the calmness in this song

Gives such a cool, ecstatic feeling while fighting Asriel. I dance while spamming the arrow keys!

It's the end of the world, but... Hopes and dreams can save the world!

This should be number 1. I'm not saying it will be, but it should.

Both sad and happy and hopeful

Spider dance is honestly my 2nd favourite. It's such a fun, cute song, just like Muffet!

So energetic and well synced to Muffet's animations, it's just the best.

This is just so energetic

My favorite, personally.

So nightmare inducing and terrifying that it's catchy, like playing the Geometry Dash level, "Peaceful".

Love the repetition in the songs and it really fits to the boss omega Flowey!

Basically panic as a song

It goes from total despair go absolute hope , and does so greatly the fact that the heavy part hits when flowey's defense reaches zéro and you star dping a lot of damage to a literal demi god juste mâles it perfect

Heck yes
1. battle against a true hero
2. FINALE
3. death by glamour
4. SAVE the world
5. either megalovania or ghost fight

I really love this theme. It's my favorite. And I also love the meaning of the battle. Through out neutral route. We see her commenting on how much she hates humans. Yet now she is protecting them.

Such a sad and heroic song!

Feel kinda sad every time hearing it because SPOILER ALERT! you have to kill undyne to win

I like the moves on the drumset, it's what attracts me to listen (and sometimes play) the song.

Papyrus is epic. Yeah. That's it. That's the comment.

It's catchy and it's in 2nd place in my top 10.

It is so fun to listen!

Just the right balance of awesomeness and hard-coreness

IT'S SO GOOOD

So jazzy it makes you diddly-darn snappity and speako like a speedo in a soothin' and jazzyo of a diddly voice.

Not sure why I like this one so much... It's just catchy! The mood is really cool.

The best in my opinion and a more epic version of hopes and dreams

Amazing yet another reason why I love it

Just amazing

This is just as good as death by glamour
So why is it 15

I want this at my funeral.

I wish this was higher

I <3 love love GOAT MOM!

TORIEL IS THE BEST

YEAH GO GOAT MOM! WE <3 YOU!

Once the second, heavier segment of it hits, I really don't understand how anyone feels anything else could top it. Opinions will be opinions and all, but it's amazing whether you prefer another song or not

Underrated, you can hear all of the themes of Asriel/flowey in this, and its amazing.

While this isn't for the best ending of the game, it's definitely a great final battle song.

Probably the most underrated theme. It’s fairly simple, yet powerful

I really like it because its just so edicting and it much better than dummy!

Just so addictive!

I think this is the theme for napstablook

I added this because I like Toriel and classical music

Sans is probably one of my favorites. You could hum this all day!

Technically not a boss theme, but it deserves a vote anyways

I LOVE THIS SONG!

In my opinion the worst boss theme. It's just too repetitive.

Surprised nobody mentioned it, I adore how this one gives kind of mid-20 century futuristic vibes
