Monster Kid: Yo.
Undyne told me to stay away from you.
She said you...
You hurt a lot of people.
But, yo, that's not [bad word]  right?
Yo, why won't you answer me?
A... a... and what's with that weird expression?
Oh...
Oh man...
(Man my h-heart's pounding right out of my chest...)
What would Undyne do?
Yo...
Y-you'd b-better st-stop r-right where you are...
'Cause if you w-wanna hurt anyone else...
...you're...
You're gonna have to get through me, first!

a‒an
Undyne...
You're...
You're hurt...

Undyne: Hurt? Ugh, I-it's nothing.
Next time, listen when I tell you to leave, okay?

Monster Kid: Undyne...I...

Undyne: I'll take care of this!
Get out of here!
...heh.. "It's nothing"...
(exhale)
No...
S-somehow, with just one hit...
I'm already...
Already...
 [bad word] it...
 [bad word] ..Alphys...Asgore...
Just like that, I...
I've failed you...
No...my body...
It feels like it's splitting apart.
Like any instant...I'll scatter into a million pieces.
But...
Deep, deep in my soul.
There's a burning feeling I can't describe.
burning feeling that won't let me die.
This isn't just about monsters anymore, is it?
If you get past me, you'll...You'll destroy them all, won't you?
Monsters...humans...everyone....
Everyone's hopes. Everyone's dreams. Vanquished in an instant.
But I WON'T let you do that.
Right now, everyone in the world...I can feel their hearts beating as one!
And we all have ONE goal. To defeat YOU.
Human. No, whatever you are!
For the sake of the whole world...
I, UNDYNE, will strike you down!

You're gonna try a little harder than THAT.

You spilled blood
You thought it easy, you thought it fun
Now I've found out, now your reign of terror's done
Families you've broken, the ones you've left in tears
Their hopes and dreams
Empower this hero's spear!
There'll be no more pain, you won't kill again
Face a [bad word] hero
The blade of evil's bane
Our future is grim, the chance to survive is slim
But we don't live or die based on your whims!
Howling of the wind, echoes of your sin
Sings of hopes and dreams, that one day might have been
Now I rise again
This will be your end
You will never break my DETERMINATION
Don't you dare give me that smile
Time to say goodbye
Fallen human child
Time to repent, for all of your pain
You will never see the light of day again
Honoring those who have gone, though you tried your best
We will carry on
We will stand strong through pain and death
We will rejoice as you take your last breath
There'll be no more pain, you won't kill again
Face a [bad word] hero
The blade of evil's bane
Our future is grim, the chance to survive is slim
But we don't live or die based on your whims!
Howling of the wind, echoes of your sin
Sings of hopes and dreams, that one day might have been
Now I rise again
This will be your end
You will never break my DETERMINATION
Everyone's hopes and dreams
Tonight they all rest on me
I'm the hero, and you're the bad guy
And tonight I refuse to die!
Protecting those who survive
So long as I fight,
we will stay alive
You are a beast who knows only to fight
But I swear I shall bring victory tonight!
You killed me once, you won't do it again
Your path of [bad word] is done
Though you [bad word] on, here I still remain
While everyone's hearts beat as one!
You never thought our lives meant anything
Your life must mean nothing as well
But we soldier on, and our victory we'll sing
Kids like you should all burn in [bad word] #33;
Real heroes fight to defend what is right
You fight for the sake of a game
You're following the path of genocide
So a [bad word] hero stands in your way!

 [bad word] it...
So even that power...It wasn't enough...?
Heh..Heheheh...
If you...
If you think I'm gonna give up hope, you're wrong.
'Cause I've...Got my friends behind me.
Alphys told me that she would watch me fight you...
And if anything went wrong, she would...evacuate everyone.
By now she's called Asgore and told him to absorb the 6 human SOULs.
*sounds of melt* And with that power..
This world will live on...
*music plays*

She didn't call for help...

And nobody came... :)
