Undertale 2: The Dark Future

Undyne was standing against a wall with Frisk at her side. Undyne was wearing her usual outfit and frisk was also wearing his usual attire. "Man... How long does it take for Alphys to get ready? She texted me saying she would be here." Frisk Shrugs in confusion. They hear a noise from afar it sounds like a familiar noise. "What the heck was that?"

"Haha! I thought if you were the scientist of the monsters then I can use this on you first." Perry says with a crazed look in his face. "Nnn.... Please. Don't!" She tries to run away but the man Catches her and holds her in place forcefully. "You're not going anywhere, Yellow Scum." Alphys pauses in time to remember all the great things that happened in her life. She starts to remember why she was even going out in the first place and the thought of that made her start to cry... "Undyne.... Help me! Just like in Mew Me-" The man shoots the dart of the gene into her heart.

Undyne and Frisk flinch when they hear a large, painful and torturous scream from the distance... It goes on for a few seconds and it slowly dies down... "What was that?" Frisk Says... "That sounded like Alphys! ALPHYS!" Then from around the corner man was holding Alphys' almost empty and controlled body... "Y-YOU!" Undyne shakes her head and Run towards the man. The man tackles her down.

"Haha... She was so easy and such a great test subject..." He says and then laughs... "Well... I am going to develop more of this stuff... I guess I can leave her where she belongs... In the dump..." He runs away and by the time Undyne gets up he is gone.

"Hello, Undyne." Alphys moves towards Undyne in a robotic way. "He... Created the gene... He-H-Help..." Undyne wraps her arms around Alphys. "NO! I WILL FAIL." Alphys pushes Undynes arms off of her and she backs away from her. She has an empty but slightly frenetic facial expression. She is speechless. She has been completely emptied out and is now corrupted. "Haha..." The thing Controlling Alphys says. "Die."

Alphys runs up to Undyne and Swings a punch at Undyne. "No... This is not you. I refuse to fight." Undyne Blocks the punch and Alphys goes behind her and swings her arm into Undynes back. "NNNGH... I... Will not... FIGHT BACK!" Undyne backs from Alphys. They stare at each other. "Alphys... PLEASE! Remember me..." Undyne chokes a bit from crying... "Remember when I you would laugh when I did something funny or blush when I was close to you... holding your hand... But now... You are trying to attack me... Kill me..." She chokes again. "Wait... No you aren't... That stupid gene is... He is. It is making your innocent and harmless soul attack me..." but Alphys grabs a piece of Glass, runs towards Undyne and Swings it. Undyne grabs her hand to block the attack. "STOP IT ALPHYS! ITS ME! YOUR GIRLFRIEND!" Undyne Gets the weapon out of Alphys' Hand and Swings it at Alphys arm.

Again they are staring at each other but closer... "A-Alphys... Respond to me..." Undyne looks down, tearing up... "Is Anime real...? IS Mew Mew Kissy Cutie our favorite anime?..." She gets closer to Alphys... "I wish... You were acting the way you were at the beach 5 years ago... but you're acting cold and empty..." She says sadly...

Alphys goes up to her and tries to attack her but Undyne puts Alphys in a choke hold... "I'm sorry Alphys... Y-You can't get changed back... I have to put you out of your misery... I... Love you..." Undyne starts to choke Alphys weakly and with extreme regret.... She stops choking... "Undyne..." Alphys Says in her normal voice but weaker... "Don't be sorry... and Yes..." She pauses as she gets closer to Undynes face... "Anime... Is real..." Alphys Kisses Undyne weakly and she falls back in Undynes arms as the life of a friend escapes their body... "....ALPHYS!" she starts sobbing into Alphys lifeless and almost died body.

"N-NO!... This isn't happening...." She screams... Frisk starts crying and he get closer to Undyne. Undyne looks at frisk as she is hugging Alphys... "She was innocent... But... At least she died in my arms..." Silence fills the room... "Frisk I don't think I told you how we met... W-we were just tweens when we met... I was throwing some old junk away when looked over and saw her... She looked amazing... I then went up to her and talked with her. We became friends and then later I fell in love with her. So we started going out... Our first date was right where we were standing..." Undyne starts sobbing and reaches in her pocket... She pulls out a box and inside was an engagement ring... I... I was going to propose to her..."

"Last night when we were cuddling and watching TV I told her I had a surprise for her... this was going to be the surprise... The reason why I brought you along is because I wanted you to see it... you did save us from being trapped underground... Alphys and Undyne got even closer up here on the surface..." Undyne looks at Alphys' Outfit... "Look at her dress..." Undyne cries more... "It's the same one she wore on our first date...!" Undyne stops and looks at Frisk. "Wait... those words she spoke right before she died..." Undyne trembles... "She wasn't completely changed yet...!" she twitches and shakes her body sadly and violently "I AM A MURDERER! I WAS GOING TO ASK HER TO BE MY LOVELY WIFE.... for... life..."

Undyne sits on the ground holding Alphys close... "I want to be with Alphys..." She says... "B-Be nice to Papyrus... Teach him the things I taught you..." A cyan colored circle appears below them... "You are not only a loser with a big heart... You're the loser that brought Alphys and I closer... And now I must join her... Goodbye... Frisk..." Frisk tries to jump and save them but a large spear rises from the cyan colored spear around them and goes through them.

Frisk jumps back... He looks up and dust flies through the wind... The dust lands onto the ground but it shapes into two hearts... close to each other... Smiling... The thing Frisk just saw fills him with... Sadness.

But... You are determined to fight for Undyne and Alphys.
