Will have some bits of "Shadow of Mordor" and "Shadow of War" . Also will have a harem for Finn and a harem for an OC that belongs to my great friend and Co-writer, TME.

Treachery swirls around the King of Ooo, as the violent factions acting against his empire grow their power in secret. His brother's family becomes increasingly fractured, as Kim Kil Wan pursues his vengeance against the man he once called 'uncle'. Meanwhile, Minerva the Finn-mom and her team strive to repair the Ark's damaged control system before the massive colony falls on Ooo.

What happens a normal kid dies and finds themselves reincarnated in their favorite show as the brother of the future queen of vampires herself. A lot of stuff, some good some bad. But one thing is for sure, a lot will change. (SI-OC)

Betty and Marceline friendship Au. What if Betty never went completely solo in trying to save Simon?

After choosing life, Finn makes amends with Flame Princess.

Simon gets the power of the crown, but he doesn't lose his sanity or Betty. The war happens and Simon and Betty find Marceline and raise her as their own. The new family face many difficult challenges. A story in which a hero will rise and help defeat a great evil in the distant future. A different Ooo will rise and take shape. Also there will be many crossovers.

This new story of Finn's is much different from the others, look to a new Adventure Time with a new Finn in tow

A detailed fanfiction idea that I feel like I put a lot of heart into. I'm sending it off into the internet in case I ever lose it. FP/Finn's relationship starting on a much healthier note, meant to be wholesome, FP is more relaxed and happy because of Finn. **Chapter 1 Dialog Added**

While exploring a new dungeon, Finn is stuck in a time loop that resets every time he opens his eyes. Will he be able to escape this loop, or will he be forced to live in it with the god-like ability to reset time whenever he wants? Wait, is being in a time loop even a bad thing?

Maybe it was the way she looked at the falling snow with childlike wonder, or the way the white flakes looked beautiful before they melted in her hair; but in that moment, Bonnie knew everything was going to be okay. High school AU. (slow burn; reupload)
