Molten Fates [TFF!Molten Freddy X Fem!Reader]

[Story is Mature due to Graphic themes not meant for younger Readers or those easily disturbed. Story was made before the introduction of Bryan's parents in season 3 in halfway through season 2, so AU is not accurate to the series, cover art not mine]
You are Bryan's younger sister, your a bit strange, but people usually believe that for you being a Test Tube kid, making you adopted to Bryan's biological parents
You have some, rather strange anomalies with your DNA strands from this as people liked to mess with it before you were ever physically existent, almost like some characters from Resident Evil in a sense
Bryan called you one day in needing of help with an animatronic he needs help with for its virus, which was FunTime Foxy, and to help with the other animatronics as another may have it as well
You get more than what you were expecting really with the remaining enemy Twisted Animatronics after you now as well, GlitchTrap after you too, and more than what you could expect with a rather "Tunsdere" like animatronic by the name Molten Freddy
But despite all of this frustration and stress, will you be able to help your brother and his friends out in the end?
But will you fall for Molten though throughout it all despite how overprotective your brother is?
