undertale x creepypasta

so it's based off two stories.
one: Music shifter
Two: back again-Futuretale
So yeah.frisk gets pregnant and chara her secretly older male twin tries to kill the children inside her but spares them so frisk won't come back...if she does everyone cares for will die.frisk knows that won't happen because of her powers. There is a little fnaf in this...Frisk is secretly foxy so yeah. Well yeah well she is three years old because she died when she was three but her recent human body was 12. (In this fanfic most woman are suppose to be married or pregnant at the age of twelve, well on the surface more than the underground) so it's been 7 years. Her human body didn't actually change. Well so in that period of time:
1 year; had two children a male and female, but female had two be in an incubator because of bad health
2 year:started murdering, nor for fun but to satisfy something to take her anger of dying at the age of 3
3 year:someone saw her right eye, that there is only a eyesocket with a white Rose blooming in it causing her to go to the doctor
4 year:the female is still in the incubator still a newborn but slowly healing
5 year: murders started in the city
6 year:the monsters are released from the underground
7 year: female newborn almost done healing
