I get if you want them to adopt a kid in your story but if its just to insert yourself and be this OP character like no. While I'm at it the fnaf characters+ Aftons aren't gods they can be be beaten by so many fandom characters Personally I can't take the videos seriously when I see (Monika-me) 

Like i'm clicking off if I see that. Plus I don't see the purpose of why add yourself to a family that canonally crumbles and the final child suffers watching all his family die around him, possibly  also hated for the incident by society.
