Summary
Frisk's determination was a helpful, powerful gift... before it became a curse.
When a dangerous entity known as "The Player" takes over, Frisk is helplessly left at the mercy of a power much higher than theirs. One outside reality, guided only by an insatiable curiosity.
At first, The Player's control would muffle their feelings and force them back underground after they escaped. Very soon, the experiments and runs become much worse.
First it was death, then manipulation. There's always something new, unfound secrets to quench The Player's endless thirst for more.
Will it ever be over? We can only wait and see...

Summary
In the small town of Hometown, everything is almost normal. Most of the towns population is made up of monsters, except for one. Kris (Age 17), the adopted child of Toriel and Asgore Dreemurr. Their brother, Asriel, attends a good college far from Hometown, as Kris goes to a fairly small high school. In the school, Kris sits with 14 other students, they are mostly silent, only talking when necessary or when they feel comfortable, often sleeping in class and not calling any attention. Susie (Age 18) is one of the students, a troublemaker who had been held back one year, nobody knows much about her, and because of her reputation, nobody dared to find out. Everything seems as it should be, until fate puts Susie and Kris into an adventure that would forever change their lives. When the duo is put up against unknown forces and powerful enemies, they will have to call upon unlikely allies, venture into new worlds, and stand together as one to save the world from oblivion... or die trying.

Summary
You wake up. The last thing you remember was you tripping and falling down a hole in a mountain. You now find yourself laid in a bed of golden flowers. Confused and overall scared, you look up. You see the sunlight: "*It's not dark yet.", you think. You get up and notice there's a small corridor, with an entrance right after it. Since apparently there is no other way to go, you decide, despite your fears, to follow that corridor and into the door.

ECHOFALLS by RubyHobbit
Fandoms: Undertale (Video Game), Underfell - Fandom, Flowerfell (the original)

Summary
ECHOFALLS is an Undertale AU based off of UNDERFELL and the ORIGINAL FLOWERFELL. if you don't know FlowerFell is actually not a FRANS AU and was taken down because people didn't want to do all the work that I am doing and create a new AU with its own story and have its own ending and its own lesson to get what they want and instead decided to just change a little of the story and make Sans (someone in his 20s or 30s) date Frisks (who in the story was at most a teen but probably still 10). Why I don't know maybe they have a competition with Sans or something. I however feel that is horrible and wrong and I want the creator to know that their story is still theirs and hopefully bring the original back.
The ECHOFALLS AU is an AU where two twin girls fall down a Chasm and wake up in the underground at different times. Both of which change the underground forever. Every time either of them dies a blue echo flower grows on them and has an echo of the last thing that was said right before they died if someone interacts with them. We start with one but end with another, will they be free or will they remain underground in eternal silence and slumber forgotten by the Humans above. -
