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)

"can even the worst person change?" "Yes... Yes I believe they can" After saving Sans from his lust for killing and collecting LOVE, Frisk resets the time line in anticipation of living a life of love with Sans in the Underground. However, when she resets, she finds herself and Sans on the surface...right in front of the UA Hero Academy. Due to the sudden change from the original storyline in the last time line, the Reset button broke, leaving Sans and Frisk in a broken timeline. Life is fine up in the surface, but things that don't belong in this world start appearing. Not completely accurate, but I don't plan on it being so. My fanfiction, my writing, but the storyline will stay generally the same. Hope you enjoy (^_^)

What if someone from our world was reborn as grillby as the original grillby? What if everything now happens more differently because grillby is now going to be more different? (Everything starts differently, gaster is still there cause grillby saved him, differently beginning, different middles, different ending, everything is different, personality included, I'll add more if i think of anything and grillby is going to be op and you won't change my blind anytime soon. Slow updates etc I'm thinking on what to do with this story because I don't think I read a story about becoming grillby before. If there is any, I would like to read them.

Nightmare is a god. Not only is he a god but a king as well. A fair and just king at that. Despite being the most feared being in the multiverse he is surprisingly the opposite of what most would believe. They believe he is a cruel tyrant when the king is actually rather caring. The only problem with the king is that he doesn't have a heir, not like he would need one. That would soon change however, all thanks to a goddess. The Goddess of Fate.

Error, God of Destruction, feared by all, did not think he would be a father, but called a mother, to six ship children. He had no idea how good of a father-mother he was, but he just couldn't leave the abandoned children in the cold. So he took them in and cared for them. Error didn't want ANYONE to know about this because...the children were one of his weaknesses. If anyone found out, he would probably die. Will Error be able to keep the secret? Or will someone find out? Read the book to figure it out! ------------- No characters belong to me, just their respective owners!
