An Alternate Adventure Chapter 1: Prolouge, an undertale fanfic

Author's Note: I'm officially obsessed with this game. I'm also obsessed with this AU I found. Basically, for those of you who don't know, Underfell is the alternate universe in which Frisk and Flowey are the only nice people in the Underground, and everybody else is evil and mean. (And humans seem to only throw away clothes from Hot Topic for the monsters to find.) I could never find any fanfiction that explained all of it, so I decided to try it myself. If I get something wrong, that's because it isn't clear what's supposed to happen in the AU. This first part isn't too long, only like 1,500 words, but the chapters will get longer after this. Enjoy!

Long ago, two races ruled over Earth: HUMANS and MONSTERS.

One day, war broke out between the two races.

After a long battle, the humans were victorious.

They sealed the monsters underground with a magic spell.

Unfortunately, over time the monsters grew hateful, and swore vengeance upon all humans.

Many, many years later…

MT. EBOTT

You wake up in a bed of bright, golden flowers. You sit up and wonder how you survived your plummet down MT. Ebott. You assess your current situation. Your favorite blue and pink striped shirt is riddled with small holes and your worn out brown boots are scuffed in several places and on the verge of falling apart. Your pants are too far gone to be of any real protection. The torn jeans revealed the, still gooey, used bandage that you had wrapped around your leg earlier to stop the bleeding of a particularly nasty injury. The stick you picked up at the top of the mountain is still in an okay condition, although slightly shorter because the top of it had broken off. You look up above you and see a distant light casting a small glow in the dark cave below. You look ahead to a small corridor that must lead deeper into the cave. Even though this isn't what you planned for yourself when you trekked up the mountain, your curiosity gets the better of you and you stand up. Your leg still hurts, and you aren't feeling particularly determined to move forward, but you simply have to know what lies ahead. So you pick up your stick, readjust your bandage and move to the next room.

You are immediately greeted by a yellow flower with a smile on its face. You briefly wonder whether you actually are dead, and the afterlife has flowers with smiles. However, as quickly as the thought comes, it goes. Your leg hurts too much for you to be dead.

The flower starts speaking to you. "Howdy! I'm Flowey. Flowey the Flower!"

You immediately relax. Flowey is pretty adorable after all, and in your ten years of experience, cute things generally didn't tend to hurt you. You can tell that Flowey is a boy; you've grown good at identifying people over the years because you have such a specific identity yourself.

Flowey is still smiling at you. "Hmm. You're new to the UNDERGROUND, aren't cha?" The yellow flower chuckles at you, but as you inspect him a little more closely, you notice that Flowey's laugh is a little forced. Almost as if Flowey's done this a few times before... Flowey continues. "Golly, you must be so confused. Someone ought to t-teach you how things wo-work around here." You did not miss how Flowey seems to stumble over his words near the end of his sentence. He seems shaken up over something.

"I guess little old me will have to do." When Flowey finishes, he looks down for some unknown reason, seeming solemn. Flowey's sadness lingers on his face as he turns and looks back up at you with a bittersweet smile. "Ready? Here we go!"

You suddenly feel the odd sensation of your heart literally thumping right out of your chest. A small, glowing, floating, red heart appears before you. You can feel it resonating with a strange inner power, and beating in time with your heart beat. The heart is contained in some kind of box which Flowey is looking at. Below the box are some words and numbers. It reminds you a bit of an RPG, where there's something showing your stats. You are at LV 1, and you have 20/20 HP. An odd tune starts to play, like it should have been a happy melody, but for some reason it is slowed down and distorted into a melancholy song.

Flowey starts to speak again, this time with an underlying tone of sadness in his voice. "See that heart? That is your SOUL, the very culmination of your being." Flowey looks like he wants to be anywhere else but here. He isn't smiling anymore, he looks very sad. Flowey continues educating you about the Underground. "Down here, monsters l-like m-m-me will try and attack you and take your soul. They'll attack you with bullets like these:" A few sharp looking white pellets appear around Flowey. You decide that you don't like them at all. Flowey resumes his lesson. "You'll have to learn to dodge them if you want to stay alive in a fight." Flowey pauses for a second, as if having an internal argument with himself.

He looks back at you. "Are you ready?" You realize after a couple seconds, Flowey is actually asking you. You nod your head yes, and he nods back in response. "Move around! Dodge as many as you can!" The bullets head straight for your soul, so you maneuver around them without being hit. Flowey smiles at you a little bit. "Great job! You're a natural. Now, your soul starts off pretty weak: 0 ATK, 0 DEF, 0 INV, a mere 20 HP. But it can grow strong if you gain a lot of LV."

Confused, you quietly ask Flowey what LV stands for. He seems surprised to hear your voice for the first time. You're a little surprised you spoke too. "What's LV stand for? It actually stands for LOVE." You look at him incredulously, not believing that. Flowey sweat drops. "Well, LOVE is an acronym too, but I'll get into that later. Anyway, to gain LV, you have t-to… kill… monsters." Flowey's voice quiets down at the end. You don't like the idea of killing anything. You tell this to Flowey, but he doesn't seem to hear you.

Four rectangular orange buttons appear out of seemingly nowhere below your stats. The first button says FIGHT with a pixel art drawing of a sword in front of it. The next button says ACT with a picture of a few soundbars in front of it. The button after that reads ITEM with a drawing of… well, you're not exactly sure what it is. The final button says MERCY. The drawing in front of it is a simple X. You get the feeling that the MERCY button would be the one you use the most.

Flowey looks at you with a dark resignation in his beady eyes. "Well? What are you waiting for? Take a swing at me with your stick kid." Your soul appears at the FIGHT button. You hurriedly move your soul all the way to the MERCY option. You press it, and you have the option to Spare.

LV 1-HP 20/20
