Top Ten Undertale Boss Themes

My favorite one! Sexy legs.

Melhor Theme de Undertale

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

Sounds itallian but robotic

The best theme in the whole game.

Wanna have a bad time?

it's good

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.

It gives a cosmic theme to it while fighting Asriel

Both sad and happy and hopeful

It's the end of the world, but... Hopes and dreams can save the world! - Delgia2k

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

The song it's self isn't great,but the remixes it inspired I enjoy.in conclusion I voted this as my favorite

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

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

My favorite, personally.

Umm...7? seriously? come on... this is awesome

Ze best.

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.

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

It's really catchy!

IT'S SO GOOOD

Somebody Included Alphys takes action, so I added the best remix of megalovania and backbone I have ever heard by far.

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

The only logical answer. - Brobusky

Haha really funny

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 <3 love love GOAT MOM!

TORIEL IS THE BEST

YEAH GO GOAT MOM! WE <3 YOU!

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

I wish this was higher - Maya159610

I want this at my funeral.

None of the people voting on this list have actually heard this theme, have they? - xandermartin98

Just amazing

Amazing yet another reason why I love it

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

I think this should be in the actual game. This is magnificence.

Amazing inktale megolovania. *claps*. Wut a masterpiece yuuush! *Humming tokyovania intenseifies*

Is this Endogeny's theme? Because it sound like dogs getting abused.

DO YOU WANNA HAVE BAD TOM - Yendks

Kinder Sans:DO U WANT 2 HAAAVE A BAD TOM! Kinder Frisk:no

I added this because I like Toriel and classical music

I LOVE THIS SONG!

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

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