fnaf1

in the game over screen we see that you get stuffed, not new knowledge but due the placement of fnaf in (my) timeline enard would still be inside Michael so he would survive and if Michael was looking for his father then he would want to keep it open so can keep looking. deeming fnaf1 jumpscares possible canon.

fnaf2

getting jumpscared in by toy animatronic wouldn't be so bad as the very small amount of remanent has there facial recognition malfunction and that's it to the toy animatronics would probably restrain you and call 911 which would get the building fined. however getting killed by toy after night 5 (when the DCI happens) they would be more hostile stuffing you into a suit and calling the cops which would get the investigation that was already going to stay on longer possibly giving us a night8, getting jumpscared by mangle would get you killed and the marionette would stuff you the witherds would stuff and endo inside of you (like phone guy says) and due to the fnaf2 nightguards being human, you would die deeming all fnaf2 jumpscares non-cannon

fnaf3

springtraps jumpscare implies that you dont die making sense because wouldn't yoy be happy if you saw your son, a way to get out without fail? springtrap would force mike to unwind the springlocks getting zombie afton outside the suit and then afton would climb inside mike like enard.

fnaf4

if we are talking about BV-dreamer and/or mike-dreamer then you would just wake up but, if we are talking about the observation chambers from SL then we get something a bit different if it is BV in the test chamber than he would probably get injured and thats it but if mike was in the chamber then the animatronics would just kill of hospitalize him. deeming fnaf4 jumpscares canon depending on what you believe.

fnaf SL

if night3 of SL foxy jumpscares us and takes us to the springlock suit starting night4 so maybe its the same for all the other jumpscared or they just take you to the scooping room so, SL jumpscares (at least one) are canon.

fnaf6

in the salvage sections we are literally told that when we get jumpscared they get lose and run into your pizzeria, during the dayshift though they would just kill you shutting the down the building due to blood and a corpse being found in the manager's office. so fnaf6 jumpscares are non-canon.
