This is my first time writing a book so sorry if it's bad. [This book is being rewritten. Also, this story is cringe read at your own risk.][I swear to God, please stop reading. This book isn't good.]😂Y/n is just your average middle school kid except that she is a fish and has a dangerous quirk, because of this she is constantly being bullied by Katsuki Bakugo and his gang telling her she can't be a hero. But with the support of her childhood best friend Izuku Midorya she is DETERMINED to be a hero and serve justice to the villains. I do not own any characters of undertale, glitchtale or My hero academia, the images and music is not owned by me…

Underfell is a dark world with the major rule of kill or be killed. Even though children are suppose to be secluded from this rule, that doesn't stop monsters from hurting children.Undyne is a monster who lives in Waterfall. Under the care of Gerson. One day while out on a walk the fish monster stumbles across a baby. Though it wasn't any monster. It was a small little baby skeleton.(the cover is only temporary, until I'm able to make a cover for the story)…

Welp! Here you go ladies! Surprisingly people are actually enjoying the girlxgirl books. Well some. So heres an Undyne x female reader book!Your name is (Y/N) (L/N). You fell down Ebott when you we're 10 years old. Ever since then Toriel took care of you until you we're old enough to get your own house. You don't remember much on what happened back at the surface since you hit your head on the way down. Over the years you grew to know pretty much everyone. But, you also grew a crush. That crush was, Undyne, Captain Of The Royal Guard. Your scared to tell her. But once you finally admit your feelings to Undyne you two soon became a couple. Once you two started dating everything seems to be getting tougher. Until one day, Chara came and did something you will never forgive her for. Will this effect your and Undyne's relationship or will it make it stronger?…

Hey guys! Welcome to my very first story called OVERTALE. It's a story about Frisk and the gang once they reach the surface, so if you haven't played the game this story will make no sense. This story is also full of spoilers so watch out!!! Also keep in mind that YOU, yeah, YOU the reader are Frisk. I wanted you guys to feel involved in the story so I wrote it so it's like you are the main character. Hope you enjoy the story! Thanks for TOBY FOX for creating the game and all of the others that helped Toby along the way . START DATE: December 9, 2015…
