The Undying rushed through the air like a hurricane─── Holding speed faster than the wind, and actions hotter than the fire. With every twist she gave, the earth erupted in astonishing light ─ Her will to defend the Underground burning brighter than the very heavens above.

Her lungs pushed her body past the brinks of death─── Swinging her spear with a deadly edge that severed the child's body time and time again. Frisk continued to respawn, but her energy refused to deplete for even a second. Lightning-blue arrows raining down from the booming sky, the entire bridge was beginning to fall down.

Soon, enemy-to-enemy were pressed up against each other─── Knife against the blade of her spear. She was determined - she would protect this world!

"────That it, you little PUNK?!" A lioness casting her head to the sky, her roar was thrust through the space of the world ─── Threatening to destroy this human. Threatening to rip their very SOUL from their body.

Frisk charges forward, and Undyne follows suit with dead accuracy─── One swipe from tiny hands follows, cutting through scales and armour, but never holding enough time to unleash more than a papercut amongst the monster's body. Undyne's black eyes surged through the darkness ─── Her grin powering forward, her spear rocketing through the head of the child.

She would kill them again, and again, and again─── And never, would she give up!

There was blow after blow left upon her body─── But it was within the light, she was able to fight on. Able to sever this child's life from their world second, after second. The two predators danced along the darkness, and with repeated swipes of their knife, Undyne's hair slowly was disappearing to the wind every time she dodged.

Her HP was depleting, but even now─── She fought on. Their shadows cast along the walls of the cave as they attacked each other again and again without mercy; SWIPE, STAB, BLOW, BLOW, SWIPE.

Frisk charged forward with silence, and Undyne leapt back with prowess─── One wore nothing but a serious expression, the other was smiling as if it was their final bout before their time to die. Undyne danced with death, and she did it proudly ─ She stood as tall as she had to, to make sure that never again, would the Underground have to live in fear.

But Frisk fought on - mightier than the monster could ever hope,
Swipe after swipe, as little damage as they did to her - it was piece by piece, her body was slowly caving away. Undyne watched on as her body was being cut away, little by little, her hair once long and beautiful, now cut jagged and short──── She dodged, she flipped, they skid along the waters, circling, and circling, and circling.

Frisk would fight on, and so would she─── But her health was going away,
How much longer would the Undying stand?

The child leaps through the air, their muscles drawn to rubber- and their lungs burning with every breath. With one downward slice, their blade saws through the space between─── Water rockets around Undyne's feet, holding up her spear to block with all her might. Frisk pushed further down. Undyne pushed further back─── The water sprayed faster, and little by little, the heroine was being pushed back.

She would fight on!
And it's with a skid of her feet, and a throw up of her hands, the child is thrown behind─── Undyne recovers from the momentary slip, reaching out, and spears being thrust into the child's battered body.

Blood sprayed along the waters, tainting the waterfalls, and making the soil smell like rot ─ There was not much more they could do, as they died, and they died, and they died.

Again, they stand up─── And the black eyes of the hero stare down,
"────How much more.. do you have in you..?!"

They fight again, Frisk moving forward─── Undyne coming to block. Her own body was beginning to give, with less than 20HP left ─And being pushed back, again, and again, and again. Her spears charged through the earth, destroying the land ─── digging so far into the skin of the child that bone was visible.

They kept recovering─── They just wouldn't stop!

BUT SHE WOULD FIGHT ON─── SHE WOULD FIGHT───

[1134 DAMAGE TAKEN].

What happens to a man, when you long to fight on─── When you have something true, and pure to endure for,

But by the end of the road, your body betrays your spirit?

With all her wounds, with all her efforts── And her scars to prove,
The sorrow on her face shows how disappointed she had become.

"────Damn it," she's reached 0HP - living on,
With nothing more than the will to protect, "───So even with THAT power..."

Her beaten armour wipes the blood from her lips─── Skin ripped apart,
No longer herself,

"──It wasn't enough...?"

Her legs shook── She still,
With nothing left but her spirit, she still raised up her spear. Her body was dead── Her eyes were nothing. Her body was paling, the Undying was...

It's with a baited breath, she gives her enemy a smile,

"───If you think I'm about to give up hole - You're wrong."

Her body bled. Her heart no longer held a beat.

"'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,"

The expression amongst the killer's face finally changes─── The passive look of Frisk suddenly changes to.. enraged. This wasn't── This wasn't how things were meant to be, right?

"Evacuate everyone."

Her grin shines forward── Her faith in the monsters leading her through these vital moments,
"By now, she's called Asgore and told him to absorb the 6 human souls──"

And it's before she has the moments to die away; to reveal the last few words of her dialogue──
To melt away, and shout out to the void that this world would live on,

The child charges in their anger. Eyes struck wide, knife thrust through the space between───
Undyne's eyes widen as her breath is caught, having no energy to move - having no heart to keep her alive.

So she closes her eyes, and accepts her fate.

Like a guillotine, the blade swings down── Aiming for her head,

But in the last few seconds, something comes between. A manly bandana── Stretched out over Undyne's neck, catching the blow - and leaving Frisk to do nothing but fall to the ground, panting in their wrath.

You stood over the kneeling Undyne, fear in your eyes─── Taking your armour.. and giving it to her.

The Undying looks up to you, black eyes no longer holding the spark of life───
But the warmth of seeing.. an old friend she used to stand by.

"..Heh.." She couldn't help but smile─ You were shaking. There was no terror like this that she'd seen, but it was with your own fire in your eyes, she was given a chance to..

"We haven't.. had a chance to talk.. have we, kid..?" Her voice was so broken.

Frisk stands away, knife almost slipping from their hands─── But it's with a thick swallow, they charge forward again. Towards you standing over the defeated warrior, declairing in their head that they were to destroy you both───

They run at you, holding up their knife,
But it's as they come close, they're impaled.

Six spears through their midsection── Leaving their soul to die away once more.

Undyne doesn't have much left, does she?
But even now ─── She has it within her.. to fight.

You look down to her, and you see something has gone so very wrong. Her skin was giving── Her sweat was soon turning to her own matter.. her body was melting away before your very eyes, and it was within your desperation,

With your tiny arms, and you're raw adrenaline, you pick her up─── Running away before Frisk had a chance to respawn. You ran with tears in your eyes, feeling her arms run to liquid, and her muscles flow through your fingers───

Eventually you find refuge in a tunnel, placing her body against a cramped wall, and crying out.
Her head lulled lifelessly forward, everything that held her together was dying away───

───But even in this state, she smiled at you.

You pathetically sniffled, reaching up to grip her cheeks - to get her to look at you,
"────U-Undyne─ Y-Y'can't go yet,

This was m-meant to be my perfect run. This was meant to be where I fixed everything and.."

The dead creature lets out a hoarse laugh── Opening her eyes,
Staring right through you.

"───It's not.. like I have a choice, you brat.." even now, she wanted to appear tough to you── To make herself seem like even now, in this death,

She was so powerful, "Don't rub it in, heh..heh..

My body's melting away── I don't even think.. my organs are here anymore.
All I feel is liquid - the reminder that.. that I've.."

"───You haven't failed!" Your cry echoes throughout the tunnel, "You've done everything you could! You always have- You always───"

It was then, you feel something press against your cheek. Her hand, wiping at your tears── You could feel her bone starting to emerge from her skin, everything else.. dying away.

"You know..
You're always so scared of everythin'.. aren't you?"

Her smile shows through her tired eyes── Body sinking lower down the wall, as almost tenderly, that thumb brushes over, and over, and over your skin, "─I still remember what you were like when we first hung out.. you ran away from me.. didn'tcha..?"

A chuckle comes from her── Hearing her liquefied lungs bubble up against her throat, "──An' then I collapsed in Hotlands because I was so keen on chasing you.. I was so desperate to capture you.

You gave me some water to cool down─── You were..

..A big NERD!"

You keep crying── She wasn't getting better. She was dying away, piece by piece.

But it was then, that the same menu as before────
APPEARS AGAIN.

* [ACT]

It's with shivering hands, you reach up to hold her own. It felt so bad── Like mud slipping between your digits. Undyne continues on, "And when you came back - when you reset, I felt so..

So alone.

It was like my best friend in the whole wide world had come back─── Just to hurt me, y'know?
It.. It fuckin' hurt."

Your brows knit together── Skin wrinkling as the tears flowed faster.

* Undyne the Undying.

"──I thought I'd lost my friend for so long. I never remembered you after you reset, but I still..
..I still felt so sad; like there was somethin' I'd let go of one day that I could never get back."

You nod against her hand── Choked sobs being SQUEEZED against your throat.
She didn't even look like herself anymore.. But even now, she still smiled on.

❤ * Check

* Atone

"But then.. you came back.
From the first moment I saw ya ─ I knew.. I knew it was you.

My.. My first real.."

You couldn't even hear her laugh underneath all the liquid. She was sad - She was sad that she had to go away, when she was so close to.. making things alright again.

But she couldn't fight forever. She was the evidence that no matter how long you try to fight─── There comes a time where you have to put down your swords, and be told...

You squeeze your hand once more against her own── The bone itself run to mush, and your tears continuing on,
You didn't even know if she could hear you anymore, but even if she couldn't...

* Check

* Atone

...You wanted to try.

"───I'm s-sorry I did that to you, Undyne," be brave - be strong like her, "I'm sorry I made you put down your guard, and accept someone only for them t-to..

To kill you, and to kill you, and to kill you again," you remembered how it felt when you were in Frisk's position── Trying to kill her over, and over, and over again, only for the heroine to win every time.

But eventually, you toughened up─── You told yourself you were the enemy.

Your determination killed her, and it was from then on - you had betrayed.. your friend.

"──I'll.. I'll try my best to be brave now, Undyne," you choke as she holds on, "I'll try my best to make sure I never hurt any more friends ever again. I'll be strong for you── I'll protect..

I'll pr-protect.."

Her hand slips past you── Dragging to the ground in a puddle of liquid,

"..Knowing you," a voice comes from the waters── The very last few seconds of her existence, "It'll be a little frantic but..I think.. you'll do a great job, kid.

Be.. Be determined. You'll win this ─ I know.."

And it's within then, that her remains are left to dust. The waters rushing along the winds── Turning to the ashen grey marks, dancing around the lights of this beautiful, beautiful Waterfall.

"..I know you'll keep this world alive for me."
