Across the Timelines [an Undertale Fanfiction]

Experiment gone wrong

  "Hi Alphys, have you seen any good anime recently?" Frisk asked as he walked into her lab with some nice cream in his hands. "I brought you some nice cream."

Shaking her head no, Alphys smiled as she shyly said, "I-I can't. I'm trying to l-look good for Undyne... SHE'S SO COOL!"

Unsure of what else to do with it, Frisk shrugged and started to eat it, not wanting it to go to waste. "So, what am I helping you with today? What are you trying to do?"

"I want to try to create this. It's from my favorite anime," she said proudly as she held out a copy of Mew Mew: Kissy Cutie, pointing at something one of the characters was holding. "I-I want to make it as a present... For Undyne. Do you think that's weird?"

Frisk smiled as he shook his head no. "That looks cool. I think she'll like it," he answered, trying to reassure his friend. Ever since he met Alphys, he knew how shy she was. She lacked confidence in herself, and it was because of that that Frisk wanted to help her. After he delivered Undyne's letter to her, Alphys has never been happier.

Together, they started building. Actually, Frisk only handed her the tools as Toriel forbid him from doing something reckless in the lab. She didn't want Frisk to come home with any injuries like last time... As the time past by, the strange object was finished.

"Does it work? What does it do?" Frisk asked, not really sure. He never actually seen the anime because he was always out playing with monster kid, or Sans and Papyrus. He noticed there was like a little lens on it, making him think it was some sort of laser, or flash light. "Can we try it?"

"S-sure, let's try it." Alphys clicked a button that was supposed to start it and aimed at some dry noodles. When nothing happened, she became confused. "Huh, th-that's weird. I made it for her to help her cook without burning down her house, but i-it's not working." Examining it closely, Frisk watched as Alphys aimed the device towards him unknowingly. He didn't think much of it at first, thinking it was broken, until it suddenly fired.

A bright light filled the lab as Frisk suddenly felt something behind him. A human's arm had wrapped itself around him, grabbing at his heart. When the light was gone, he slowly turned to see a frightening face behind him. "Ah! Wh-who are you? Alphys, what happened?"

The strange boy looked around just as confused as Frisk was, but strangely satisfied by the turn of events. He picked up the knife he had dropped to the floor and answered, "I'm Chara. Who are you, and why are you hanging out with a monster?"

"F-Frisk, maybe you should get away from him," Alphys suggested. "Where are you from, Chara?"

Chara looked over at her once before smirking, "you were the one spying on me, aren't you? Man, I didn't think something like you lived this long. I guess that's why you live alone."

"Hey, that's not nice!" Frisk shouted, trying to push off Chara's arm. "Apologize to my friend now, or I'm going to tell Undyne on you!"

Chara smiled as he held Frisk tighter, almost as if challenging him. "She's alive, huh? Fine, go tell her, pipsqueak. Fatty here doesn't seem like she's going to be a lot of fun anyways."

"Frisk, i-it's okay. Really," she looked down at her feet as she wiped away some tears. "L-let's just try to figure out what happened... Oh, and please do me a favor. Don't tell Toriel about this. She made me promise not to let anything happen to you."

"That goat is still alive?!?!" Frustrated now, Chara pushed Frisk to the ground stepping away from them to look around. "Is everyone still alive? What did you do when you first went to the Underground?!"

Confused now, Frisk looked back at Alphys as she did some complicated looking work on her computer before shaking with fear. "Oh no, what did I do? Undyne is going to kill me."

"I can do it, if you want," Chara commented, playing with his knife. Frisk stepped away from him now, curious to know the problem.

Alphys simply looked at him as she said, "Frisk, I-I think that's you. I-it sounds crazy, but I think it's you from another time." Alphys noticed the dust on Chara's jumper and became afraid as she recognized it. "Y-you didn't... Kill anyone, did you, Chara?"

With his creepy smile, he answered, "maybe just a few. Toriel, Papyrus, Undyne, Mettaton, and was looking for that stupid comedian when I suddenly appeared here."

Horrified now, Frisk stood in front of his friend protectively. Not wanting Chara to step close to his friend, he shouted, "if you want to hurt Alphys, you have to get through me first!"

"Okay, not a problem. Do you really think a pipsqueak like you can beat me?" Holding up his knife, he charged, ready to kill Frisk before suddenly stopping. "What? What's going on?" he asked, confused as he tried to bring the knife across the other boy. "Why can't I kill you?"

Relieved now, Alphys let go of the breath she'd been holding. "Th-that's a relief. I do-don't know what I would have told Toriel if you got hurt, Frisk."

"What do we do? I think we need to tell mom, or maybe Undyne about him, Alphys. What if he tries to hurt someone?" Frisk asked, not taking his eyes off Chara. "Maybe Sans has an idea?"

With a sigh, she said, "o-okay. We'll tell them, but you n-need to be the one to watch him, okay? I don't think having any monsters watch him is a good idea..."

"Let me get this straight. The weakling is going to watch me? What is he going to do to stop me?" Chara questioned. In all honestly, he'd rather have someone like Undyne watch over him. Fighting her was a great challenge as she refused to die. If she were gone, Alphys would never receive word to evacuate everyone. On second thought, if he could "befriend" Frisk, maybe he could make Frisk destroy everyone alongside him. They could be partners, just like he and flowey used to be. "You know what, go nuts. Try to keep me out of trouble."

Frisk was filled with determination to protect his friends. Chara was determined to show the true power Frisk had hidden inside.

Alright, so I know that Frisk/Chara are gender neutral, but in this story, they're both boys. I hope I managed to do a decent Alphys and Chara. This story is going to be taking place in the Underground, but in a time after the barrier's gone. Everyone is free to leave the underground, but I guess just consider it home. Anyways, I hope you like this. Sorry for it being short, but I'll add another chapter, hopefully longer, soon.
