[Undyne]
Even though my SOUL feels like it's about to break
I can't let it, there is way too much at stake!

DETERMINATION is what's keeping me here
But hatred is what makes me draw my spear

None of your crimes will go unpunished today
I will personally make sure that you pay!

[Undyne the Undying, spoken]
Ha! You're gonna have to try a little harder than THAT!

[Undyne the Undying, sung]
You're a disgusting human, I will strike you down
You have emptied Waterfall and Snowdin Town
This is no longer about getting to your SOUL
Protecting them from you is my only goal

I see your knife stained red from the blood
There's no hint at all of anything good
I'm gonna save all their hopеs and dreams

I have to fight, duty to the land
I am еvery monster's final stand
Our hearts beat as one, we fight as a team
My will to fight, forged by every monster's beliefs
We stand firm together, we fight through the grief!
What's left of the land believes in me now
I'm the Spear of Justice, I can't let them down!

I stand firm, fight until my dying breath
I'll make sure there is no more monster death
Even if it means we fight forever

Papyrus stopped coming to his meetings
He stopped answering my phone call greetings
I know what you did to him, selfish brat

Asgore brought me to this point, trained me every day for years
Now I can't even speak to him, all I hear are his tears
He tries to act strong, but I know he's struggling to hold together
I can't let you get near and hurt him, never, ever, ever!

If I let you get past me, you'll hurt everybody else
I'll end you now before my body and my will to fight melt
Fight or try to run away, either way I'll destroy you
The plans we have, if only you knew...

What's this feeling through my body, why am I still falling down?
I will never let myself fall, I have to protect the crown
You're gonna have to try a little harder, to make me give in
You're fighting against a true heroine!
[Undyne the Undying, spoken]
Alphys told me humans were determined. I see now what she meant by that. BUT I'M DETERMINED TOO! DETERMINED TO END THIS RIGHT NOW!

Ugh... You see how strong we are...

WHEN WE STAND TOGETHER?!

[Chorus]
Real heroes never fear the pain or death
Every soldier fights until their final breath
Dedicating all their lives to just one cause
Serves the kingdom and applies the rules and laws

[Undyne the Undying]
Years of training giving all my blood and sweat
Getting to the point where nothing is a threat
Every battle will just be another day
Every human's just another one to slay!

[Monsters, spoken]
You've got this, Undyne!

Stay determined!

We put our faith into you
Keep fighting, Undyne

Don't give up, Undyne!

[Undyne the Undying]----------[Chorus]
Raising my spear----------------Real heroes never fear the pain or
-----------------------------------death
To the sky-----------------------Every soldier fights until their final
Loyal soldiers keep-------------breath!
----------------------------------Dedicating all their life to just one
----------------------------------cause
Marching on!-------------------Serves the kingdom and applies the
----------------------------------rules and laws!
Shouting in one----------------Years of training, giving all her

Clear voice!---------------------Getting to the point where nothing
Every single dream-------------is a threat
----------------------------------Every battle will just be another day

-----------------------------------slay

[Undyne the Undying and Chorus]
Honor the ones who are gone
Because of this filthy scum
Away from home in the wild
Trying to survive alone

[Undyne the Undying]
Just because I fight, it doesn't mean
I don't have my own fragile heart
If I could, I would go back in time
So I could prevent all these deaths

[Chorus and Undyne the Undying]
The real heroes stand until the end
But the biggest fight is inside
Feelings clashing, while you pretend
That the bloodstains one day will dry

When you hear these voices in your head
Telling you it will be alright
But your heart keeps telling you again
Real heroes have to fight (on)!
