I suck at descriptions, but here goes.

Sans sets himself the task to locate one of the greatest heroes, and one of the most powerful beings, of all time. Percy Jackson. Will the new team be able to work together and defeat the rising threat, gaining new assets along the way, or will Percy struggle to get over the (slightly altered) Second Giant War, and Annabeth's death, and the Timeline fall to ruin?

Broken || A Riordan Universe Story by bookfangirl04

||HIGHEST RANK: #1 in KaneChronicles|| ||#20 in HeroesOfOlympus|| ||PJO Watty Award Winner|| This is a Percy Jackson/Kane Chronicles/Magnus Chase Fanfiction. Set after Blood of Olympus. A COMPLETED STORY What happens after the second war? Will things go back to the way they were? Or are our demigod heroes too broken to be fixed? What happens when the biggest force they've ever faced comes to Camp? Will they be able to survive with the help of the Egyptian & Norse Universes? This is mainly focused on the seven plus Nico. Here is an excerpt: "It's been one day since Gaea was defeated. I thought I'd feel some sort of a big weight being lifted off of my chest. But it was the exact opposite. I feel like this isn't the end, that something terrible is going to happen. As a daughter of Athena I guess it was in my blood to be overly suspicious. I didn't tell the rest of the six yet. Everyone was grieving for all the casualties; including Leo Valdez. I could barely hold onto the concept that our annoyingly funny Latino elf was gone. Phoebe, Naomi, Celyn were just at the beginning of the list of casualties. We got very lucky, since that list didn't stretch for long. I got lucky, I was still alive. Leo would still be alive if it weren't for the cut on my leg. That. Dam. Cut. I was the reason Gaea woke up in the first place. The guilt was eating me up alive."

When Wand and Sword Collide || Percy Jackson/ Harry Potter by galaxiasgreen

Percy Jackson wakes at Hogwarts. Harry Potter wakes at Camp Half-Blood. Neither know who they are, where they are, or where they come from - but when the line between demigod and wizard blurs and a sinister prophecy arises, Harry and Percy must unite with Hermione, Ron, and Annabeth before it's too late. [WINTER 2023 UNDERGOING REVISIONS] --- Harry and Percy swap roles story, with an original plot and prophecy! Altered Timeline, taking place in 'modern day', after the war with Gaia assuming everyone survived (as this was written pre-HoH and BoO) with no canon from MCGA or ToA, and around the start of Harry's sixth year, where no events of HBP have occured (i.e. Snape is still Potions Master and Draco has not been chosen to kill Dumbledore). Percy and Harry are around the same age. Chapters alternate between 1POV for Percy and 3POV for Harry. [Luth art by Rowen Satell.]

You have been warned.'~ ((Unedited)) After Chara fell into the Underground, they met Asriel a monster inhabitant of the Underground. Soon after that, Chara joins a new family, but their ambition to keep everyone happy goes a little overboard and Chara is flung into a reality of destruction and hopeless wonder. Then many long years later they meet the beloved Frisk, who fell into the Underground, similar to themselves. Eventually everything Chara thought they knew correctly is turned upside down and they as a person are changed forever. ~'The game Undertale belongs to Toby Fox and some of the dialogue is ripped straight from the game itself, too.'~

Reset (Sans x Older!Frisk) by error-code-707

There are some things you just can't take back. No matter how many times you reset. After breaking free of Chara's grip, Frisk decides to do one final reset before defeating Sans or proceeding to the throne room. But some memories last longer than others, and broken trust isn't easy to repair. Female, aged-up Frisk. Starts out canon and then diverges. Eventual Sans x Frisk. Undertale was created by Toby Fox. I do not own Undertale, nor any of the characters. Some violent action scenes. Cover art is by amazing artists at http://www.zerochan.net/Undertale,Fanart and http://www.zerochan.net/Chara+(Undertale),Fanart

Undertale:Secrets by ItIsComic

Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great. Inspirations: The "Better Times" trilogy by: @ANinnyMouse42 "Royal Blue" by: @dealialestine Started: 24th May 2021 Finished: 29th December 2021 A full 7 months of great fun with this book!
