[Alphys]
Mettaton, no! No no no, come on, get up!

You can't die now!

Okay... there we go...

[Mettaton]
(REBOOTING...)

[Alphys, monologue]
So... it's you... the one who... killed all of my friends. I've been watching you. I saw... everything you did... to everybody. A-At first, I... I was so scared. I was.. absolutely terrified of... o-of what you'd do to me when you found me...
But... but then I-I spoke with Undyne... and, and she told me everything was going to be okay! Even if... even if she had to die for that to happen... She gave her battle with you her absolute everything. But deep inside she knew... She knew that she had no chance... As much as she didn't want to admit it. I-If she had no doubt... She wouldn't have let me go ahead with my plan

[Mettaton]
(REBOOT SUCCESSFUL.)

[Alphys, monologue]
Which... was to harness the power I'd been hiding for so long. The power to change fate. The power I extracted from the human SOULs that ASGORE kept locked away...
It's the power I call... "DETERMINATION"
You and I both know what I'm talking about, don't we? It's a power that you have too. The word that echoes through the emptiness when you finish killing everybody in an area

The word that you think nobody else hears
I-I wasn't going to use the power like this... originally, I had plans to work in Mettaton's design... But we couldn't finish that in time. So...
Even though I.. I know what this is going to do to me eventually... It's gonna give me the means to stop you
I am NOT going to run away this time. If I'm going down... I'M TAKING YOU WITH ME!
[Alphys, sung]
Suddenly, things went wrong

[Mettaton NEO]
Things didn't go to my song

[Alphys]
But we have a plan B

[Alphys and Mettaton NEO]
Let's fight on, you and me!

[Mettaton NEO]
Round two, here we go

[Alphys]
Suddenly, things went wrong

[Mettaton NEO]
Time to face NEO

[Alphys]
Things didn't go to his song

[Mettaton NEO]
Welcome to my show
[Alphys]
But we have a plan B

[Mettaton NEO]
Though you won't see the end of the episode

[Alphys]
Go, fight on, Mettaton!

[Mettaton NEO]
Ha!

[Alphys]
Well, I didn't want to have to do this
But now, it's hit or miss
I don't think I ever had a choice
So now, I have to fight and find my voice

[Alphys and Mettaton NEO]
Monsters have always been resilient
But now it's all gone silent
We are everybody's last stand
A final hope for all the land

[Mettaton NEO]
Monsters, humans, I'll be adored by thousands
After you go
Because of NEO
[Alphys]
I don't want to fight you
But it seems I have to
You killed my friends
I'll show you your end!

I feel a fire, deep inside
And it's forcing me to fight you
This is my duty to them all
After what I did

We are every monster's final stand
And we will win together
And we've chosen what we must do
Mettaton, go!

[Mettaton NEO]
Now, like I said
Before I was rudely cut short
Your whole onslaught has gone on for far too long!

But now I am ready to end your existence
Don't worry, everyone, Mettaton is here!
I can't tell you how much you're hated by monsters
But, just know, you don't have a fan, unlike me!

With the support of the Underground (well, who's left)
We will take you down and take back the surface!
Now take the hit, give it your very best shot

My my, what's with that look, darling?
Did you think I would keel over like that-

AGH!

If this is my death, I'm going to make you WORK for it

[Alphys]
No, Mettaton!

Now he's gone
It's your fault
That was your last life taken
I'll make sure
You will hurt no more

I should have killed you
Way back when
After you left the Ruins
Dust on your hands
Evil grin, I was so foolish

Now I know what I had to do
It's too late, this is my fault
I guess it's time for me to go
I won't miss this world
As I reach my final hour
I realise your power
Up on high, sits our king
Soon you will hear him sing

I know what you plan to do
Force this whole world to end
I remember you, my friend...
