You've gone far to reach here, and now you'll be judged by my own tears, the golden scales of love and exp they all weigh towards evil I can see

You could have been a saint but you just chose the one path I hate, Now I can't let you go further, cus kid you're a monster murderer

All have fallen in your wake, now you must die for all the lives youve taken, out of this hole I won't let you climb, You're really gonna have a bad time

I know what you did to her, after all you killed my brother, Undyne should've taken you out but that's not how it goes

Maybe even mettaton or even the spiders though, kids like you belong in [bad word]  working me to the bone!

Everybodys safe and gone and cheering me on, from a safe haven, secret to all because of Alphy's genius and guts, I'm a lazybones so now you have my word, kid I'm gonna really dunk your world

Even though I know that this reality's dumb, birds will still be singing monsters living once my deed here's [bad word] done, you're the monster here far from a human girl, don't blink cus I'm gonna dunk your world

Medley motifs:
Deep underground below the earth
There lies a world unknown to all those roaming above
And even soon a tale will sure end
About poor choices and hate, without a single loved

Strong and relentless, that's why he's the bestest, always takes a rest its [bad word] saaans
With one HP and his 0 defenses, with just speed and wit, its [bad word] saans

He won't let you live, now number 1, its death by slaughter, there's a pun you never [bad word] your way

Even if you die, he knows with time, you might get faster, but y'know, your win spells disaster

Here at last, one whose death, your dark soul, with the rest,
We'll be free, my buddy, but I jest, I'd never ever be your friend

Maybe just once when things repeat 
We can be pals jamming to the beat
Laughing at jokes simultaneously
Alphys, [bad word]  her, undyne, and me

But as for you pile of pure evil, 
Next time just choose to be more civil
