Male Afton Reader X Security Breach

Y/N Afton is the oldest child of William and Claire (I think that's their name's, sorry for everyone who knows but if you can correct me then please do and I'll fix it) and an exact replica of William. He's the older brother to Michael Afton. At 16, he was killed by his father in front of Michael, who was 9 at the time. After that, he was stuffed into an Anamatronic that was given the name Nightmare by Michael. Slowly realizing the things that was happening, he figured out that he had 2 younger siblings named Chris and Elizabeth. Y/N watched from the shadows until he found out that William was favoring the younger ones while Michael was in anger and so was he. William never showed affection towards you or Michael when they were younger. Y/N and Michael tormented Chris. Michael during the day and Y/N at night until the day he died. Y/N felt no remorse and neither Michael but he needed to show that he was "traumatized" by his death. Let's see what happens next
