No more playing games
You are gonna pay
For all that the humans have done to us and

Now face the fight head on
I will remain strong
As our battle commences are you ready?

Come, casting fear aside
Swelling up with pride
I will face you and finish what the king

Began, with the final soul
We will gain control
The surface will be ours once again, and so

Hey, don't you run from me
This is your destiny
To fall before me onto your knees

No mercy, I, Undyne, will strike
And I'll take your life
Take your soul for the hope of us all

Long, long ago
When the first human fell below
They were taken in by the king
And queen, monsters had mercy
How was it repaid?
We lost everything on that day
So we wait here
In the hapes that another human comes astray

(So now wield your book and fight)
You are the seventh human so low
(There's no place where you can hide)
So you have to be taken down
(You will not escape my spear)
This is not as easy as spellwork
(I can see you trembling like in fear)
You know justice is coming

Now, this told me
That you humans aren't trusing
You are built with determination
Whatever the hell that means

I had believed
That you humans were kind at need
But because of that it
Doesn't mean that I'm going to go easy

En garde, now's the time to fight
And with all my might
I will see you soul given to ASGORE, he'll
Free all the underground
We'll be free soon now
I will ensure the future of monsters and

Hey, stop running away
This is your last day
Just accept your ending and give in, there's

No way you will win
You will pay for your sins
And you'll face my spear of justice
