(If you don't like either Undertale, or Steven Universe, you do know you could just ignore this right? I only made this because, SU is, my favorite show, and UT is my favorite game... Also, head cannon Frisk, and Chara genders, light gore at times, some swears, and spoilers for both of these things! You have been warned)
There are countless of universes... And in each universe contains their own unique worlds... But some day... Something happened to them... Something that made two certain universe switch places... Everyone in these universes are completely oblivious... Well expect two young kids... Can their two worlds ever be the same again? Maybe they'll just forget about it all... Or maybe... They'll make the wrong choice...
Huh? I got up and looked around... I seem to be in a dark room... I looked down... I saw a field of golden flowers... With these weird onion like things, in the middle of them... I looked at them for a few seconds...
"Golden Onion Flowers... They must've broken your fall." A voice said... I looked around for the voice but I saw nobody... It sounded so... Familiar... I felt really sore... I rubbed my joints... Wait... I looked down at myself and saw that I wasn't wearing my star shirt... This shirt was a blue sweater, with a few pink stripes... Weird...
"Hello?" I called out... I then got up, on my feet... I kind of groaned while doing so. "Garnet?" I called out... "Amethyst?" I yelled... "Pearl?" I cried... But nobody came... All I can do is proceed down a hallway... I gulped nervously... At the end of the hallway, I saw a large, purple door, with this weird, symbol... I looked through the door and saw... Onion? He had petals around his head. I stepped into the room...
"Howdy! I'm Onion! Onion the onion flower!" He said... I just looked at him, dumbfounded...Why was he here...? Where are the Crystal Gems... Wait a minute... ONION COULD SPEAK!? I've could've swore my jaw hit the floor... Onion looked awkward, then he cleared his throat... "You're to the Underground, arent'ca?" He asked. I nodded my head. "Golly! You must be so confused!" I nodded my head again... "Someone oughtta teach you how things work around here! I guess little ol' me will have to do!"
Everything turned black, expect, what looked like, was my gem... I kind of have a bad feeling about this... "See this gem?" Onion asked... I then started to move around... I then realized that I was see-though... I then jumped up... Wait... Like this, I can levitate? I then got down... If only my floaty powers were like this...
"This is your soul, the very center of your being..." I nodded my head... Okay... I think I'm getting this... "Your soul, starts out weak, but you could gain a lot of exp, to increase you LV." He explain... Oh, so this is like a video game?
"Does LV stand for level?" I asked Onion. He giggled... Ugh... So wrong...
"Of course not, silly!" He shouted, while smiling. "It stands for love, of course!" He said, seeing more cheerful with each word. "You want some love don't you?" He asked... I hold up my hands, and stilly shook my head...
"No thanks... I'm good..." I said, while smiling, nervously...
"Don't be like that! Come on!" He told me... Okay... I guess I don't have anything to lose? I know... Onion isn't the first person, who'd I call for help but... He wouldn't try to kill me would he? He then made some white pellets appear... "Up here, love is spread through little white... 'Friendliness Pellets...' You want some love, don't you?" He asked.
"I guess..." I told him... I took a deep breathe... He then stuck out his tongue, then winked...
"Okay then! Move around, and collect as many as you can!" He said, as the pellets headed my way... I ran into them, and-
"OOOOOOWWWW!" I screamed as they struck me... I fall to the ground, too weak to get up... It felt like something punch me, with fire... I look at a bar that was label hp... I only had one left... I looked down at myself, and saw a giant hole, in my shirt, and something that only seem to be burnt skin... I groaned in pain, as I put my hand on it... It felt wet... I look back at my hand to see it completely cover in blood... I then look back at Onion afraid, and weak... Who seemed to be laughing at my pain...
"YOOOOOOOU IDOIT!" He screamed as his face look liked a monster's... "IN THIS WORLD, IT'S KILL, OR BE KILLED! WHY WOULD ANYONE PASS UP AN OPPORTUNITY LIKE THIS!?" He then summoned more 'friendliness pellets' I gasp... They were circling me, so even if I wasn't too weak I'd died... I felt tears in the back of my eyes... "DIE!" He shouted, then laughed, as the pellets inched closer to me... I cuddle up into helpless ball... I cried into my hands, as I just laid there... Then.. All of a sudden... I felt like if the pain stopped...
I looked back at Onion, who seemed to be angry, and confused... Then, out of nowhere, a fire ball appear, knocking Onion away... Then... I couldn't believe my eyes...
"What a terrible creature, torturing a poor, innocent, youth!" Garnet said... Instead of wearing her normal clothes, she wore a purple rope,with long white sleeves, and the symbol of the door was on her chest, she was also missing visors, showing her three, different colored eyes... I don't care though! I ran up to her, and hugged her... She hugged my back, while rubbing my head... I buried my face into her rope, sobbing...
"There, there, young one..." She told me... After almost dying... I felt like I lost the ability to speak... "I'm Garnet, Caretaker, of the Ruins," she explained... Wait... What? I would have ask her what she meant, but I couldn't stop crying... "I pass through here everyday, to see if something new falls down here... You are the first hybrid, who has come here in awhile..." I looked at her confused..."G-g-ga... Garnet?" I asked her... I looked at her confused... She looked at me with a worried look on her face.
"Yes, little one, that's me... Is something wrong, child?" She asked... Does... She not know who I was...?
"I-I-it's just... I..." I said, as I was still sobbing, not much as before but still...
"It's okay, child... As long as you're with me, I won't let anyone hurt you... Come with me, small one... I'll show you the way, through these catacombs." Garnet said, as she grabbed my hand, and went through an other purple door, with the same symbol. I looked at her, about to ask if she remembers me but...
I woke up inside of a bed and I looked around... Huh? Wait... There were a bunch of shelfs filled with action figures, books, and junk... In front of the bed, there was a cheap T.V, with a Game cube on it... I looked to the saw, and I saw a living room on a lower level... I got up, and made my way downstairs...
"Toriel? Sans? Papyrus? Undyne? Alpyhs? Asgore?" I called out for my friends... But nobody came... I then looked around... Where am I even? I tried to check my stats, but nothing happened... I tried to reach my last and still... Nothing happened... I then gulped nervously... In my world... It was like I was in a video and now... I looked down at myself, to see I was wearing a reddish-pinkish shirt with a yellow star on it...
I've been reading some of Sans' old books and it suggested some, bat shit, insane theories like... They're multiple universes... And each one is different... Some even have the ability to Bree like games, and sometimes some universe could switch but... Was it actually true? I should probably asked Sans... He knows a lot about this stuff...
I sighed, and walked out of the house... I found myself at a beach... I looked up at the sky to see it was early morning... Hmm... Wait! If that book was true... And if my game was like a video game... Could that mean... That person could change the world... My world...? I finished a pacifist route, not so long ago... But could he still fuck up things for me, and ruin my home?
