MEMORYTALE --- Your Best Friend (Undertale AU)

A scientist and her greatest achievement and her greatest mistake

"ALPHYS ALPHYS ALPHYS. WHAT ON EARTH ARE YOU DOING?" The egocentric robot/ghost thing asks his body's creator. Alphys fiddled with the bag of Determination and Dust in her hands.

"OH. I SEE, YOU FEEL LIKE ITS YOUR FAULT THAT UNDYNE DIED. DARLING, EVEN IF YOU TOLD HER NOT TO FIGHT THE HUMAN, SHE WOULD HAVE ANYWAYS. SHE'S UNDYNE," Mettaton said with a dramatic sigh.

"M-mettaton! y-y-you're not h-helping," Alphys said, her stutter worse than the usual.

"I'M JUST STATING THE FACTS DARLING. NOW, HOW IS MY NEW BODY COMING? I WANT TO GIVE THIS HUMAN A SHOW THEY'LL NEVER FORGET! DRAMA! ROMANCE! BLOODSHED! MOSTLY BLOODSHED!" Mettaton said with a flourish. Alphys pulled out a cube.

"I j-just need t-to install it. It h-has l-l-lower defence b-but I hope t-the HP m-makes up f-for it," The royal scientist said. Mettaton grabbed it gingerly.

"AND! A-and it l-looks w-way c-cooler then the o-original d-design," The lizard monster ending with a faint blush while pulling out a diagram of the design.

"I SEE WHAT YOU MEAN WHEN YOU SAID... DIFFERENT. IT LOOKS BETTER FOR STOPPING THE HUMAN THOUGH! IT NEEDS TO BE STOPPED! AND I LIKE THE WINGS, EVEN IF THEY WEREN'T MADE TO WORK," Mettaton concluded. "YOU SHOULD INSTALL IT SOON, AND THEN GET TO WORK EVACUATING," Mettaton would smile if his robotic features allowed it, "I'LL DISTRACT THE HUMAN. AFTER ALL, I WAS BUILT TO BE A HUMAN ERATICATION ROBOT FOR ASGORE!"

"Y-yeah..." Alphys grumbled.

"DO YOU HAVE A SAFE SPOT TO HIDE THE MONSTERS?" Mettaton asked.

"W-well I don't w-want to use it but... D-did you k-know there's a lab under t-t-this one?" Alphys said. She was talking about what was dubbed the TRUE LAB by herself. Its where she kept the amalgamates, but she had to let go of her fear if she wants monsterkind to live.

"PERFECT ALPHYS-DARLING! NOW INSTALL MY NEW FORM AND THEN WE'LL BE READY!" Mettaton cheered. Alphys sighed.

"W-well I'm g-going to h-ave to t-t-turn you o-off," She said. Mettaton winced.

"IF YOU HAVE TO, SO BE IT," He said with a small sigh. Alphys tugged on a few wires. The robot fell to the ground. She looked at the gap that originally she was going to put the EX form and sighed. She placed the NEO body there instead and hooked it up to a switch. Now all Mettaton had to do to change was flip the said switch. She smiled but her eyes didn't smile along with her mouth. She didn't know how much could go to hell in one day.

And she never got a chance to tell Undyne she loved her.

She turned Mettaton back on and told him about the switch.

"GOT IT ALPHYS. AND DARLING? GOOD LUCK," Mettaton said, in a moment of sincerity.

"ITS TIME TO GIVE THIS HUMAN A SHOW THEY'LL NEVER FORGET!"

Alphys found evacuation was somehow easy. She used a announcement system to tell all of the hotlands where to go and then boarded off the second floor with lasers. She would do the same with level three, but Muffit would refuse to leave, even when Alphys came in-person to tell her to move her and her spiders.

All in all that was a lot of work. She didn't regret asking Sans for help.

And now (what seemed to be in Alphys mind) the more important matter.

Undyne.

She walked over to her house, using some passages away from the human's gazing eyes, and placed her dust down. What would be her favourite thing? Her giant sword they made together? Her piano? That letter on the table..?

Alphys walked over to the letter and picked it up. It had a heart on the front and said To Alphys.

A letter? For her? Alphys couldn't help but open it up.

Dear Alphys,

I wrote this letter just to say how much I love your passion. Every moment I think of you, I just want to sigh. Watching human history together, spending time in the garbage dump, every moment spent with you is and ADVENTURE! FULL OF PASSION AND HARD WORKING!

So what I need to say is, I love you Doctor Alphys. Would you be mine?

-Undyne <3

Alphys cried.

And she kept crying.

Undyne loved her back.

And now it was too late.

Then she knew what Undyne would want.

She kept the dust close to her heart.

---

Mettaton was ready. It was showtime. He would do what Alphys made him to do.

Protect not only monsters, but humanity as well. Monsters stopped going to the lab a few minutes ago and he knew what time it was

ITS SHOWTIME DARLINGS!

He looked at pictures of the human a while ago, to reconise them, though he thinks that he'll know why that much dust was trailing after someone. He knew what he was getting into.

But he never got to with Blooky goodbye... And it was too late now.

---

The tiny golden flower ran out of snacks a long time ago, but with every LOAD that the human did, he got them back, so he didn't mind. He never got UNDYNE angry enough to do some weird anime transformation before, and this was INTERESTING. He thought that monsters couldn't hold that much Determination but oh gosh he was wrong. This was the most amusing thing that happened since CHARA came back. Too bad this wont last forever but its fun to watch right now.

And she melted to death? Awesome! And they're going back to the tem shop? Yay! he can stop hiding...

Wait no Doctor doofus is here. Oh gosh how did he hate his 'creator' he just wanted to rip her up into little shreds and laugh.

And laugh.

And laugh.

And keep laughing.

Its so funny.

He watched as she picked up Undyne the Dying's dust and cry. Oh he knew about her 'secret crush'. He used that against her oh so many time.

And he couldn't stop laughing, drowing away in his own tears.
