The Alien Hero of the Underground (Ben 10 X Undertale)
This story follows the storyline of if Ben 10 travelled the Underground with Frisk. Feel free to notify me of any errors in the story. I hope you enjoy. (I do not take credit for any artwork I use throughout the story.) (Undertale and Ben 10 both belong to their respective creators.)Complete
Reunitedtale
This is an AU of Undertale, which belongs to Toby Fox. Basically, it's what would happen after a Genocide Route, and if Chara had feelings. Instead of quotation marks for dialogue, I used an asterisk, as in the game, and I went with the NarraChara theory, where Chara narrates for Frisk. Instead of different fonts for dialogue, as I could not use fonts, I used bold, italic, underlining, and so on. Because there were so many characters, each type might be used more than once.Complete

Murdertale
An Undertale AU i created... All the characters are overly aggressive(except Flowey) and try to kill every human they see. the last human to fall into the underground is Frisk, and they meet many monsters who initially try to kill them, until Frisk teaches them the benefits of being nice. this takes at the same time as Undertale, but is completely different. it is also similar to horrortale because that is the AU that inspired me. all the characters belong to toby fox The cover art was created by RenSabreComplete
Saving Them (an Undertale fanfiction)
The barrier is broken, monsters and humans are living in peace, everyone is happy except for one person. Frisk has been getting waking nightmares about not saving Asriel. They want to save him to erase all guilt and to be with their friend. But Asriel isn't the only one that needs to be saved. Something, someone lurks inside Frisk's soul. Someone deadly and has a hunger for power, and can kill anyone they want. A/N Frisk and Chara are both gender ambiguous in this story. Also there will be a little bit of Frisk x Asriel in this story, but this is not a Frisk x Asriel fanfiction. Credit to @karinacat59 for the cover. Undertale belongs to Toby Fox and none of the characters are mine.Complete
